Summary Title: ADU Ordinance Revisions
Title: PUBLIC HEARING: Recommendation of an Ordinance to the
City Council Amending Palo Alto Municipal Code Section
18.42.040 Pertaining to Accessory and Junior Dwelling Units.
The Proposed Ordinance is Exempt from the California
Environmental Quality Act (CEQA) Pursuant to Public
Resources Code Section 21080.17 and CEQA Guidelines Section
15061(b)(3). For More Information, Please Contact Clare
Campbell at clare.campbell@cityofpaloalto.org.
From: Hillary Gitelman
Recommendation
Staff recommends that the Planning and Transportation Commission (PTC) take the following
action(s):
1. Find the proposed draft ordinance exempt from the provision of CEQA pursuant to
Public Resources Code Section 21080.17 and CEQA Guidelines Section 15061(b)(3);
and
2. Recommend to the City Council adoption of an Ordinance (Attachment A) amending
Palo Alto Municipal Code Section 18.42.040, Accessory and Junior Accessory
Dwelling Units.
Report Summary
On May 8, 2017, City Council adopted Ordinance No. 5412 amending Title 18 (Zoning) of the
Palo Alto Municipal Code to implement the new State requirements related to Accessory
Dwelling Units (ADU) and Junior Accessory Dwelling Units (JADU). These new regulations have
eased the development requirements for ADUs for property owners and support the creation
of additional, more affordable, housing units. With the implementation of the new regulations,
the City has seen a significant increase in the number of ADU permits filed. In 2017, 31 ADU
applications were submitted for review, whereas in previous years, the City had an average of 4
ADUs reviewed each year.
City of Palo Alto
Planning & Community Environment Department Page 2
Although the local regulations have only been in effect for nine months, staff has encountered
some challenges implementing the current code and has prepared proposed revisions to try to
address these concerns. This report also discusses Council direction to make ADUs available to
low and moderate income households and options to address illegally established ADUs. The
following is a list of the proposed ADU code revisions:
1. Clarify that ADUs may be established in all zoning districts that permit single-family use
2. Clarify that the setbacks for detached ADUs apply to the basement level
3. Clarify the bonus lot coverage and floor area to apply to existing homes constructed as
of January 1, 2017
4. Clarify that detached ADUs are not subject to the maximum 50% rear yard coverage
5. Reduce the height limit for detached ADUs located within identified Eichler tracts
6. Clarify that the replacement parking provisions also apply to JADUs
7. Allow replacement parking to be located within driveways located in a street-side
setback
8. Allow existing driveways to be expanded to accommodate replacement parking
9. Clarify when accessory structures may be rebuilt to comply with technical building codes
when converting to a new ADU
Additionally, there are a few other minor clarifications to correct references and improve
readability.
Background
In October 2015, the City Council approved a Colleagues Memo that directed the PTC to review
the Palo Alto Municipal Code (PAMC) related to ADUs and recommend strategies to increase
production of these units. Following this, the PTC conducted two Study Sessions in January and
July 2016 (reports #6462 & #6944), just prior to the State of California adopting ADU and JADU1
legislation in September 2016. In response to the new state ADU regulations, the City prepared
a draft ordinance to incorporate the mandatory state requirements and some optional
provisions with the existing local regulations. The PTC reviewed the ordinance on November 30,
2016 (report #7368) and made recommendations. In March 2017, the City Council held its first
public hearing on ADUs (report #7517) and discussed in-depth the ordinance, making
substantial revisions. On April 17, 2017, the Council adopted the ADU ordinance with further
refinements (reports #7921 & #8048), which became effective on June 8, 2017. The City Council
also directed staff to provide a quarterly report on ADU permits and to conduct a Study Session
with the PTC to analyze the results of the ordinance, which was done on December 13, 2017
(meeting minutes) and January 10, 2018 (report #8773 & meeting minutes).
1 The establishment of Junior Accessory Dwelling Units (JADU) as a permitted use was not required by state law
and was left to the discretion of the local jurisdiction. With the local adoption of the ADU regulations in April 2017,
the City Council allowed for these JADU units in Palo Alto.
City of Palo Alto
Planning & Community Environment Department Page 3
Prior to the implementation of the City’s ADU ordinance, the State regulations that became
effective on January 1, 2017 governed all ADU permit applications submitted for review in the
City. Once the City’s ordinance became effective on June 8, 2017, all ADU permit applications
not already approved were subject to the new local regulations.
In total, the City has reviewed 38 ADU applications since the State and local regulations were
implemented. In 2017, the City received 31 permits to establish ADUs, which is far beyond the
average of four units per year that the City has historically been getting. We can see that the
new ADU regulations have been very successful in encouraging development of this housing
type.
As part of the ADU code update process, staff has set up a project webpage
(http://cityofpaloalto.org/gov/depts/pln/advance/accessory_dwelling_units_regulations_updat
e.asp ) to provide current information to the public.
Updated State Regulations Effective January 2018
In 2017, the City adopted comprehensive regulations related to ADUs to conform to state law
that became effective on January 1, 2017. Subsequently, the state Legislature passed two
additional bills AB 494 and SB 229, signed by the Governor in September 2017, clarifying the
previously adopted ADU legislation. On February 26, 2018, the City Council adopted Ordinance
#5430 that included modifications to remain consistent with state law and minor clarifications.
The changes are summarized below:
State law was revised to clarify that an ADU may be constructed on sites with either an
existing or proposed single-family dwelling.
With respect to ADUs established through conversions of space within an existing single-
family home or an existing accessory structure, the state legislation required that such
conversions be allowed in any zoning district where single-family residential is an
allowed use.
The changes above were previously reviewed by the PTC and adopted by the City Council by
Ordinance #5430. The draft ordinance included with this report reflects those changes.
Staff is aware that other ADU-related amendments are being considered by the State
legislature in another pending bill SB-831
(https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=201720180SB831). Staff will
address those changes if they are approved.
Discussion
Staff has reviewed over 30 applications and has had many more conversations with property
owners regarding ADUs and it is from this experience that staff is recommended the attached
ordinance. It should be noted that the local ADU regulations have been in place for a short
City of Palo Alto
Planning & Community Environment Department Page 4
time, and as more time passes and more projects are reviewed, staff will be able to provide
additional feedback and analysis of the ADU provisions, but it is clear that recent changes have
increased the interest and production of ADUs locally.
Proposed Amendments
Many of the proposed code clarifications identified below were considered by the PTC in two
recent Study Sessions in January 2018 and December 2017. There are some discussion items
from the Study Sessions that have not been included in the draft ordinance, including:
refining the definition of ADUs;
removing the owner-occupancy requirements;
adding an opt-out provision; and,
prohibiting the siting of ADUs in front of the home.
These items have been removed from consideration because staff does not believe, based on
public and commissioner comments, that there is not a compelling need for a change.
Since the PTC reviewed conceptual changes to the ADU regulations, the make-up of the
commission has changed and many of the comments received offered different perspectives on
how to address the identified issues. There was a suggestion for an ad hoc committee to
participate in the drafting of a new ordinance, but one was not ultimately formed. Based on the
foregoing, staff sought to advance language that would help address some administrative
challenges and improve the effectiveness of the ordinance. Prior PTC comments are available
and previously linked in this report. The section below summarizes the issue and how it is
addressed in the ordinance.
1. Clarify that ADUs May be Established in All Zone Districts that Permit Single-family Use
The current regulations are not as clear as they can be with regards to identifying which zoning
districts allow for development of ADUs and JADUs. The code generally refers to allowing these
units in zones that permit single-family uses for attached and detached ADUs and for JADUs. To
eliminate ambiguity, staff proposes adding language that identifies all the applicable zones that
allow single-family development, and therefore, allows for ADUs and JADUs when a single-
family use is established.
2. Clarify Setbacks Requirements for Detached ADUs Basements
Detached ADUs may be permitted in required rear and interior side yards. ADUs may also have
basements. It has been unclear, however, based on other basement zoning restrictions in the
code, whether or to what extent a detached ADU basement may encroach into a required yard.
The proposed amendment clarifies that a basement may be located under the building
footprint of the detached ADU structure and must maintain the minimum setbacks that apply
to the detached ADU (i.e., maintain six feet clear from all interior and side property lines).
City of Palo Alto
Planning & Community Environment Department Page 5
3. Clarify Bonus Lot Coverage and Floor Area Provisions Apply to Existing Homes Constructed
prior to January 1, 2017.
The general intent of providing bonus lot coverage and floor area is to give some development
flexibility for existing developed sites that may be at or near the related maximums allowed.
With these bonus provisions, the additional lot coverage needed for an attached or detached
ADU would be 100% exempt for many properties, and up to an additional 175 sq. ft. of floor
area would be allowed. Below is the existing language from the code:
18.42.040(a)(4) Lot Coverage/FAR
A. An accessory dwelling unit shall be included in the lot coverage and FAR
requirements applicable to the parcel.
B. Exceptions:
i. Lot Coverage. When the development of an accessory dwelling unit on a parcel
with an existing single family residence would result in the parcel exceeding the lot
coverage requirement, the accessory dwelling unit shall not be included in the
calculation of lot coverage applicable to the property, so long as the parcel meets the
underlying zoning district's minimum lot size requirement or is substandard by no more
than ten percent (10%) of the underlying zoning district's minimum lot size requirement.
ii. Basement FAR. In the R-1 district and all R-1 subdistricts, basement space used
as an accessory dwelling unit, or portion thereof, shall not be included in the calculation
of floor area for the entire site, providing the measurement from first finished floor to
grade around the perimeter of the building is no more than three (3) feet.
iii. FAR. When the development of a new one-story accessory dwelling unit on a
parcel with an existing single family residence would result in the parcel exceeding the
maximum floor area, an additional 175 square feet of floor area above the maximum
amount of floor area otherwise permitted by the underlying zoning district shall be
allowed. This additional area shall be permitted only to accommodate the development
of the accessory dwelling unit.
The code specifically states that these bonuses are given when development of an ADU is on a
site “with an existing single-family residence.” Staff believes this takes into consideration that
existing developed lots that previously were unable to establish an ADU, but now can, may
have insufficient area to accommodate the accessory unit. The bonus allows flexibility for
existing conditions to promote this housing alternative. New construction has a variety of
options to plan for and design an ADU on the lot and is not as constrained by existing
improvements, floor plans, or other accessory structures that may be located on a lot.
The scenario that staff has encountered is that property owners who are building completely
new homes also want to take advantage of these bonuses. Many new homes maximize
permitted floor area and the interest for additional floor area sets forth a two-step process
whereby someone can build a new home and receive final approve, thus becoming an ‘existing
home’, and then file plans for an ADU and an additional 175 square feet. Clearly this is a policy
discussion that requires balancing the need for housing while preserving neighborhood
City of Palo Alto
Planning & Community Environment Department Page 6
character. By establishing a clear date by which existing homes can take advantage of these
bonus is one approach toward clarifying what is understood to be the Council’s intent when
drafting the language and eliminates a time consuming and bureaucratic two-step process to
achieve additional floor area.
PTC Study Session Comments: Three commissioners were in favor of applying the bonuses to
existing and proposed homes and two commissioners were in favor of only allowing it for
existing homes (where ‘existing’ would need to be defined). There was also a suggestion to
eliminate the bonus altogether (01/10/2018).
4. Clarify that Detached ADUs are Not Considered Accessory Structures Subject to the
Maximum 50% Rear Yard Coverage
The R-1, R-2, RE, and RMD development standards require that no more than 50% of a required
rear yard be covered by accessory structures [e.g. PAMC 18.12.080(b)(6)]. There has been some
debate as to whether ADUs are subject to this provision, which if it were, could be problematic
for some property owners. Existing (and retained) garages along with other accessory
structures located on a parcel could restrict a new detached ADU from being established on
some properties. Since ADUs are not accessory structures, but rather accessory dwelling units,
staff has not applied this 50% cover restriction. The proposed code amendment reinforces this
perspective and makes clear the standard does not apply for ADUs.
5. Reduce the Height Limit for Detached ADUs Located Within Identified Eichler Tracts
On January 18, 2018, at a community meeting regarding the draft Eichler Guidelines, staff
received input regarding reducing the height of ADUs in Eichler tracts. The current ADU height
limit for a detached unit is 17 feet and one story. The eaves of a one-story Eichler home are low
due to the slab-on-grade construction that was used; typical one-story Eichler homes are nine
to 11 or 12 feet tall. Limited follow up discussion took place with the Historic Resources Board
(HRB) in meetings on January 25 and February 22, 2018, which resulted in a recommendation
that ADUs should not exceed the height of the primary home on the lot. There are 31 identified
single family Eichler Tracts that contain approximately 2,700 properties. The proposed
ordinance includes new height restrictions of 12 feet for detached ADUs and that attached
ADUs be no taller than the primary residence at the area of attachment. The intent of the lower
height limit is to reflect the size and type of construction typical of these properties, respect
neighborhood character and preserve the sense of openness and privacy enjoyed by residents
in these tracts.
6. Clarify that the Replacement Parking Provisions Also Apply to JADU Development
A JADU is only permitted within the existing building envelope of the primary dwelling unit, and
must, at a minimum, utilize one existing bedroom. It could be possible that a JADU incorporates
a portion of a garage for the new living unit. In this circumstance, the current provisions are not
clear about the requirements for replacement parking for the primary residence if all or a
City of Palo Alto
Planning & Community Environment Department Page 7
portion of the garage was utilized for the JADU. To address this, staff recommends that the
replacement parking provisions for ADUs also be applied to JADUs. Specifically, this approach
requires any required covered parking be re-established on site, but, consistent with State law,
gives the owner flexibility as to how to provide that required parking space in terms of location
and whether it is covered or uncovered. Similar to the city’s local provision for ADUs, JADUs by
State law do not require any parking.
7. Allow Replacement Parking to be Located Within Driveways Located in a Street-side Setback
State law specifies that required replacement parking (i.e. for the primary home) may be
“located in any configuration” on the subject property. The existing regulations allow
replacement parking to be located in the front yard setback on an existing driveway as an
uncovered space. In the case of corner lots, the code is silent on allowing parking in the street
side setback. Many corner lots have just the one driveway located on the street side and
allowing replacement parking in this location on a driveway would be a reasonable
accommodation for these types of lots. Staff suggests that replacement uncovered parking be
allowed in the street side setback similar to what has been permitted for the front yard setback.
8. Allow Existing Driveways to be Expanded to Accommodate Replacement Parking
As mentioned above, the current provisions allow required replacement parking for the primary
dwelling unit to be located within an existing driveway located within the front yard setback. In
the review of ADU permits, the issue of allowing existing driveways to be expanded to
accommodate replacement parking has been raised. In the R-1 district, the code allows
driveways (and walkways) to be established providing the front yard remains 60% permeable. It
is staff’s recommendation that existing driveways in the front yard, and not street side yards,
be allowed to expand to accommodate replacement parking only, when done in association
with the establishment of an ADU or JADU.
9. Clarify when accessory structures may be rebuilt to comply with technical building codes
when converting to a new ADU
Staff has encountered ADU proposals that included the conversion of existing non-habitable
space (e.g. garage, accessory building, etc.) that had a legal non-complying element, such as a
setback encroachment; and these types of conversions are permitted with the ADU regulations.
The issue that has emerged is that during the permit review process, it comes to light that the
legal non-complying structure is not structurally sound and cannot be converted to an ADU, as-
is. To be building code compliant, the non-complying structure must be demolished and rebuilt.
The general zoning rule is that once a legal non-complying structure is removed, all new
construction must be code compliant (Section 18.70.100(b) Noncomplying facility –
Replacement).
City of Palo Alto
Planning & Community Environment Department Page 8
The general intent of the ADU code was to allow the conversion of existing structures to create
living units, including the conversion of legal non-complying structures. But, the circumstance
of requiring existing non-complying structures to be rebuilt (retaining the non-compliance) to
accommodate the new units was not fully considered. At the PTC Study Session, the options
discussed initially were at the opposite ends of the spectrum, where at one end all new
rebuilds, regardless of circumstance, should be fully zoning compliant, and at the opposite end,
allow reconstruction of non-complying structures, or portions thereof, to be rebuilt retaining
the non-complying condition.
Where the need to rebuild existing accessory structures has been presented to staff, a decision
was made to allow reconstruction. The proposed ordinance continues to advance this concept
but also includes some specific parameters to ensure there is no enlargement to the degree of
any non-conforming standard and requires a minimum three-foot setback from interior side
and rear property lines.
City Council Follow-up Discussion Items
At the March 7, 2017 Council meeting regarding the ADU regulations, Council directed staff to
return in 2018 with additional information regarding the two issues below. These issues were
briefly discussed at the PTC Study Session.
Options to Make ADUs Available to Moderate or Low Income Residents
City Council directed staff to explore further the possible options to make ADUs accessible to
moderate or low income residents, seniors, people with disabilities, or public employees. This
type of program reflects the larger concern regarding the lack of affordable housing in Palo Alto
and the greater Bay Area. Staff continues to seek PTC feedback for options on how best to
implement such a policy.
One consistent comment staff hears from interested parties is that the development impact
fees to establish an ADU are too high, nearly $10,000 per unit. These fees have been a concern
for many wanting to construct ADUs, but are assessed to support city services, parks, libraries
and other programs that benefit the community, including residents of an ADU. For some
property owners, it may be worthwhile to deed restrict their ADU as affordable housing for a
period of time (for example 10 years) in exchange for reduced or waived impact fees. In such
circumstances, a property owner may be less interested in generating rental income and more
interested in providing independent living facilities for a relative with disabilities or aging
parents. For others, reducing or waiving the impact fees would not likely be a sufficient
motivator to deed restrict the ADU to a certain income level. The City of Pasadena recently
implemented this kind of a program.
Another possible approach would be to partner with an organization that can provide financing
in exchange for affordability. As an example, Housing Trust Silicon Valley, a local non-profit
organization based in San Jose, is currently developing a pilot program that would provide low-
cost flexible loans to homeowners for the purpose of constructing an ADU in exchange for their
agreement to rent the units at affordable costs to low- and middle-income earners. The
City of Palo Alto
Planning & Community Environment Department Page 9
Housing Trust’s funding “will be used to make capital loans to homeowners — who can easily
spend $100,000 or $200,000 on ground-up construction of an ADU. But the Housing Trust also
intends to create an educational outreach program — involving classes, workshops and
technical assistance — to help homeowners navigate the ADU process.”2 The partnership
option ideally would place responsibility of the program management on the agreeable non-
profit organization.
Given sufficient staff and financial support, the City could also offer technical and educational
assistance. For example, the city could develop prototype designs for ADUs that can be readily
utilized for the permit process and can be approved more expeditiously.
Strategies for Legalizing Illegally Constructed ADUs
As with the item above, on March 7, 2017 Council directed staff to return in 2018 with options
and discussion of mechanisms to bring existing unpermitted ADUs into compliance, including
when existing ADUs do not meet the new standards.
There are a few cities in the bay area that have implemented protocols to legalize illegal ADUs.
These cities include San Francisco, Santa Cruz, and Oakland. Generally, the units are required to
be building code compliant for all health and safety concerns, and then special consideration
was given to other non-complying development standards (e.g. setbacks, height, lot coverage,
etc.).
Staff has considered what could be an appropriate method to review and support the
legalization of unpermitted ADUs. The City currently has a Home Improvement Exception (HIE)
process that could be utilized for this legalization purpose. The City would require that the unit
be compliant with all life safety standards as required by the building codes and then, on a
case-by-case basis, review the existing zoning conditions to determine what is appropriate for
the project. Other than the size limitation, the Director would have the discretion to waive
development standards using the HIE review process to accommodate legalization of the unit,
providing it is deemed safe for habitation. The overall objective would be to allow an ADU that
is safe for habitation and would not be considered a nuisance.
Such programs, however, can create other challenges and should be considered carefully.
Illegal units that cannot meet building codes or are not approved through a city process would
have to be removed and existing tenants would be displaced. It may be that illegally established
ADUs may cost too much to be structurally upgraded resulting in further displacement. Then
there is the question of how to implement a program. The Council would need to consider
whether these units are addressed on a case by case basis when brought to the city’s attention,
or if there is a brief amnesty period where owners of illegal units could seek permits to legalize
these units. Again, not all units would likely be approved. And, the administrative time

establishing and following through on such a program would be significant. Presumably,
building permit and HIE review fees would cover the cost of staff time, but this would take time
away from processing other applications.
Staff welcomes other feedback from the PTC to forward to the City Council on both of these
policy issues above.
Environmental Review
The proposed code amendments have been assessed in accordance with the authority and
criteria contained in the California Environmental Quality Act (CEQA), the State CEQA
Guidelines, and the environmental regulations of the City. Specifically, the proposed
amendments have been determined to be exempt from further environmental review pursuant
to CEQA Guidelines Section 15061(b)(3) (Review for Exemption) because the activity is covered
by the general rule that CEQA applies only to projects which have the potential for causing a
significant effect on the environment, and it can be seen with certainty that there is no
possibility that the activity in question may have a significantly effect on the environment. The
ordinance is also exempt under Public Resources Code Section 21080.17 that applies to local
ordinances implementing State regulations related to accessory dwelling units.
Public Notification, Outreach & Comments
The Palo Alto Municipal Code requires notice of this public hearing be published in a local paper
at least ten day in advance. Notice of a public hearing for this project was published in the Palo
Alto Weekly on March 16, 2018.
For the discussion in this report, staff did send out a notification email to an established group
of interested parties and the meeting was noted on the City’s ADU project webpage.
Next Steps
Upon recommendation from the PTC, staff will forward the staff recommended ordinance with
agreed upon changes to City Council for review. In instances where a majority of the PTC has a
different recommendation from staff, that viewpoint will be represented in the staff report
along with implementing language for the Council’s consideration. Only one ordinance,
however, will be presented to the Council, which is anticipated to occur in June.
Alternative Actions
In addition to the recommended action, the Planning and Transportation Commission may:
1. Recommend adoption of the draft ordinance to the City Council with modifications.
2. Continue the discussion to a future PTC hearing with the expectation that a
recommendation to the City Council would be forwarded that time.

units, in order to provide for variety to the city's housing stock and additional
affordable housing opportunities. Accessory Dwelling Units shall be separate, self-
contained living units, with separate entrances from the main residence, whether
attached or detached. The standards below are provided to minimize the impacts of
accessory dwelling units on nearby residents and throughout the city, and to assure
that the size and location of such dwellings is compatible with the existing or
proposed residence on the site and with other structures in the area.
(2) Applicable Zoning Districts
The establishment of an accessory dwelling unit is permitted in the following zoning
districts when single family residential is a permitted land use: Single-Family (R-1),
including subdistricts; Two Family Residential (R-2); Residential Estate (RE); Two Unit
Multiple Family Residential (RMD); Open Space (OS); Multiple Family Residential (RM);
and Planned Community (PC).
(2)(3) Minimum Lot Sizes
A. In the R-1 district and all R-1 subdistricts, RE district, R-2 district, and RMD
district, and properties zoned Planned Community (PC) where single-family
residential is an allowed use, the minimum lot size for the development
establishment of an accessory dwelling unit is 5,000 square feet.
B. In the OS District, the minimum lot size for the development establishment of
an accessory dwelling unit is 10 acres.

A. An accessory dwelling unit shall be included in the lot coverage and floor area
ratio FAR requirements applicable to the parcel.
B. Exceptions:
i. Lot Coverage. When the development establishment of an accessory
dwelling unit on a parcel with an existing single family residence, which was
legally permitted and existing as of January 1, 2017, would result in the
parcel exceeding the lot coverage requirement, the accessory dwelling unit
shall not be included in the calculation of lot coverage applicable to the
property, so long as the parcel meets the underlying zoning district’s
minimum lot size requirement or is substandard by no more than ten
percent (10%) of the underlying zoning district’s minimum lot size
requirement.
ii. Basements FAR. In the R-1 district and all R-1 subdistricts, basement space
used as an accessory dwelling unit, or portion thereof, shall not be included
in the calculation of floor area for the entire site, providing the
measurement from first finished floor to grade around the perimeter of the
building is no more than three (3) feet.
iii. Additional Floor AreaR. When the development of a new one-story accessory
dwelling unit on a parcel with an existing single family residence, which was
legally permitted and existing as of January 1, 2017, would result in the
parcel exceeding the maximum floor area ratio, an additional 175 square feet
of floor area above the maximum amount of floor area otherwise permitted
by the underlying zoning district shall be allowed. This additional floor area
shall be permitted only to accommodate the development of the accessory
dwelling unit and shall not be applied to the primary residence.

unit or junior accessory dwelling unit may be located on any lot subject to
this sectionConversion of an accessory structure to an accessory dwelling
unit may require rebuilding or substantial renovation to comply with the
California Code of Regulations Title 24, as adopted by the City of Palo Alto. In
such instances, and where the existing accessory structure does not comply
with applicable accessory dwelling unit development standards in the zoning
district, the structure may be renovated or rebuilt, provided that:
A. If the existing structure does not comply with the applicable
development standards for accessory dwelling units in the zoning
district, the renovated or rebuilt structure shall not increase the
degree of non-compliance, such as increased height or size, or
further intrusion into required setbacks;
B. The renovated or rebuilt structure provides a minimum three foot
setback from any interior side and rear lot lines, and 16 foot
setback from any street side property line, if applicable; and

(1011) Parking
A. No additional parking shall be required for accessory dwelling units.
B. If an accessory dwelling unit replaces existing required covered parking,
replacement spaces shall be provided. When a garage, carport, or covered
parking structure is demolished in conjunction with the construction of an
accessory dwelling unit, any required replacement spaces may be located in
any configuration on the same lot as the accessory dwelling unit. To comply
with this requirement, uncovered or tandem spaces may be provided on
existing driveways within the required front and street side yards; and covered
parking and mechanical automobile parking lifts may be located in required
side and rear yard setbacks in compliance with Section 18.40.050. , including,
but not limited to, within the front setback if on an existing driveway, as
covered spaces, uncovered spaces, or tandem spaces, or by the use of
mechanical automobile parking lifts. All new parking spaces and structures
shall comply with development standards of the underlying zoning and the
applicable parking design standards in Chapter 18.54, except as provided
below:.
i. The Director shall have the authority to modify required
replacement parking spaces by one foot in width and length upon
finding that the reduction is not detrimental to public health, safety
or the general welfare.
ii Existing front and street side yard driveways may be enlarged to
the minimum extent necessary to comply with the replacement
parking requirement above. Existing curb cuts shall not be altered
except when necessary to promote public health, safety or the
general welfare.
(b) Junior Accessory Dwelling Units
(1) Purposes:
This Section provides standards for the establishment of junior accessory dwelling units,
an alternative to the standard accessory dwelling unit. Junior accessory dwelling units
will typically be smaller than an accessory dwelling unit, will be constructed within the
walls of an existing single family structure and requires owner occupancy in the single
family residence where the unit is located.
(2) Development Standards. Junior accessory dwelling units shall comply with the following
standards:
A. Number of Units Allowed: Either one accessory dwelling unit or one junior
accessory dwelling unit, may be located on any residentially zoned lot that
permits a single-family dwelling except as otherwise regulated or restricted by
an adopted Coordinated Area Plan or Specific Plan. A junior accessory dwelling
8
March 2018
unit shall only be located on a lot which already contains one legal single-
family dwelling.
B. Size: A junior accessory dwelling unit shall not exceed 500 square feet in size.
C. Lot Coverage/Floor Area Ratio:
i. A junior accessory dwelling unit shall be included in the calculation of lot
coverage and FAR floor area ratio applicable to the property.
ii. A primary residence lot with a junior accessory dwelling unit shall be
permitted to develop an additional 50 square feet of floor area above the
maximum amount of floor area otherwise permitted by the underlying
zoning district. This additional area shall be permitted to accommodate
the junior accessory dwelling unit.
D. Owner Occupancy: The owner of a parcel proposed for a junior accessory
dwelling unit shall occupy as a principal primary residence either the primary
dwelling or the junior accessory dwelling. Owner-occupancy is not required if
the owner is a governmental agency, land trust, or housing organization.
E. Sale Prohibited: A junior accessory dwelling unit shall not be sold
independently of the primary dwelling on the parcel.
F. Short term rentals: The junior accessory dwelling unit shall not be rented for
periods of less than 30 days.
G. Location of Junior Accessory Dwelling Unit: A junior accessory dwelling unit
shall be created within the existing walls of an existing primary dwelling, and
shall include, at a minimum, the conversion of an existing bedroom.
H. Separate Entry Required: A separate exterior entry shall be provided to serve a
junior accessory dwelling unit, with an interior entry to the main living area. A
junior accessory dwelling may include a second interior doorway for sound
attenuation.
I. Kitchen Requirements: The junior accessory dwelling unit shall include an
efficiency kitchen, requiring and limited to the following components:
i. A sink with a maximum waste line diameter of one-and-a-half (1.5) inches,
ii. A cooking facility or appliance which does not require electrical service
greater than one hundred and twenty (120) volts, or natural or propane
gas, and
iii. A food preparation counter and storage cabinets that are of reasonable
size in relation to the size of the junior accessory dwelling unit.
9
March 2018
J. Parking. No additional parking is required beyond that required at the time the
existing primary dwelling was constructed. Any required parking displaced
with the establishment of a junior accessory dwelling unit shall be restored in
compliance with Section 18.42.040(a)(11)(B).
K. Fire Protection; Utility Service. For the purposes of any fire or life protection
ordinance or regulation or for the purposes of providing service for water,
sewer, or power, a junior accessory dwelling unit shall not be considered a
separate or new unit.
L. Deed Restriction. Prior to the issuance of a building permit for a junior
accessory dwelling unit, the owner shall record a deed restriction in a form
approved by the city that includes a prohibition on the sale of the junior
accessory dwelling unit separate from the sale of the single-family residence,
requires owner-occupancy consistent with subsection (b)(2)(ivD) above, does
not permit short-term rentals, and restricts the size and attributes of the
junior dwelling unit to those that conform with this section.
SECTION 2. Any provision of the Palo Alto Municipal Code or appendices thereto inconsistent with
the provisions of this Ordinance, to the extent of such inconsistencies and no further, is hereby
repealed or modified to that extent necessary to effect the provisions of this Ordinance.
SECTION 3. If any section, subsection, sentence, clause, or phrase of this Ordinance is for any
reason held to be invalid or unconstitutional by a decision of any court of competent jurisdiction,
such decision shall not affect the validity of the remaining portions of this Ordinance. The City
Council hereby declares that it would have passed this Ordinance and each and every section,
subsection, sentence, clause, or phrase not declared invalid or unconstitutional without regard to
whether any portion of the ordinance would be subsequently declared invalid or
unconstitutional.
SECTION 4. The Council finds that the adoption of this Ordinance is exempt from the provisions
of the California Environmental Quality Act (CEQA) pursuant to Public Resources Code Section
21080.17 and CEQA Guidelines sections 15061(b), 15301, 15302 and 15305 because constitute
minor adjustments to the City’s zoning ordinance to implement State law requirements related to
accessory dwelling units as established in Government Code Section 65852.2, and these changes
are also likely to result in few additional dwelling units dispersed throughout the City. As such, it
can be seen with certainty that the proposed action will not have the potential for causing a
significant effect on the environment.
SECTION 5. This ordinance shall be effective on the thirty-first date after the date of its adoption.
