Zoning Ordinance Text Amendment 
Z-TA-2-24-Y
September 30, 2024 
Application No. Z-TA-2-24-Y: Amend the Phoenix Zoning Ordinance Chapter 2, 
Section 202 (Definitions) to add new definitions and revise existing definitions regarding 
Accessory Dwelling Units and related residential terms; amend Chapter 6, Section 603 
(Suburban S-1 District—Ranch or Farm Residence) and Section 604 (Suburban S-2 
District—Ranch or Farm Commercial) to comply with HB 2720; amend Section 605 
(Residential Estate RE-43 District—One-Family Residence), Section 606 (Residential 
Estate RE-24 District—One-Family Residence), and Section 607 (Residential R1-14 
District—One-Family Residence) to comply with HB 2720 and increase permitted lot 
coverage; amend Section 608 (Residential Districts) to comply with HB 2720; amend 
Section 609 (RE-35 Single-Family Residence District) to increase permitted lot 
coverage; amend Chapter 7, Section 701.A.3 (Projections) to comply with HB 2720; 
amend Section 703.B (Landscaping and Open Areas In Multiple-Family Development) 
to differentiate the addition of ADUs from multi-family developments; and amend 
Section 706 (Accessory Uses and Structures) to clarify wordings and comply with HB 
2720. 
Staff recommendation: Staff recommends approval of Z-TA-2-24-Y as shown in the 
proposed text in Exhibit A. 
BACKGROUND AND PURPOSE 
This text amendment is a response to House Bill 2720, approved by the Fifty-Sixth 
Legislature, Second Session (2024) which modified the Arizona Revised Statutes to 
require municipalities to allow Accessory Dwelling Units (ADU) on single-family lots.  
The City of Phoenix currently complies with some of the provisions of HB 2720, but not 
all of them.  This text amendment will bring City of Phoenix zoning regulations in 
compliance with the new State regulations regarding ADUs.   
HB 2720 includes a clause which prohibits cities from regulating ADUs in any manner if 
regulations compliant with the bill are not adopted and effective by January 1, 2025.

PROPOSAL 
Staff recommend changes to existing sections of the zoning ordinance to comply with all 
provisions of HB 2720.  Staff also recommend increasing the permitted lot coverage in 
certain zoning districts, since the new State regulations require a minimum of two ADUs 
be permitted per lot with a single-family home.   
 
DESCRIPTION OF THE PROPOSED TEXT  
The proposed text amendment includes three main components: 1) new and revised 
definitions; 2) revision of existing City of Phoenix ADU regulations to comply with HB 
2720, and 3) revision of lot coverage permissions for certain districts in order to comply 
with HB 2720. 
 
1. New and Revised Definitions 
 
HB 2720 requires that the City allow a minimum of one attached and one detached 
Accessory Dwelling Unit per lot with a single-family home.  Definitions for the 
following have been added: 
 
• Accessory Dwelling Unit, Attached 
• Accessory Dwelling Unit, Detached 
 
The definition of “Accessory Dwelling Unit” has also been revised slightly to comply 
with HB 2720. 
 
2. Revision of Existing ADU Development Standards  
 
The following regulations have been revised to comply with the requirements of HB 
2720, as follows: 
 
• The number of ADUs permitted is being increased from one to two ADUs per 
lot having a single-family home. 
• A third ADU is also permitted per lot when the minimum lot size is one acre, 
and at least one of the ADUs is considered “Affordable Housing” (requiring a 
deed or other restrictions on the property).   
• Design review of ADUs no longer require that an ADU match the exterior 
design, roof pitch or finishing materials of the single-family dwelling. 
• Setbacks for both attached and detached ADUs have been reduced to 5 feet 
where adjacent to a side property line. 
 
Short-Term Rentals in ADUs 
 
This text amendment proposes to remove the current City prohibition of using an 
ADU as a Short-Term Rental (STR).  Arizona Revised Statutes §9-500.39.B 
provides a limited list of items related to STRs which municipalities are permitted to 
regulate, and prohibiting use of an ADU as an STR is not included.   Perhaps more

Staff Report: Z-TA-2-24 
 
September 30, 2024 
Page 3 
 
importantly, HB 2720 includes a new item specifically regarding how a municipality 
may require an owner to reside on the property if more than one ADU on a property 
is licensed for use as an STR.  This provision will be addressed separately as part of 
the licensing requirements outlined in City Code, Chapter 10, Article XVI – Short 
Term Vacation Rental to comply with HB 2720.  
 
3. Increase of Lot Coverage Permissions in the RE-43, RE-24, R1-14, and RE-35 
Zoning Districts 
 
In the City’s first amendment to allow ADUs in 2023 (Z-TA-5-23-Y), certain districts 
did not have lot coverage increases provided, since those districts had historically 
been allowed “guesthouses”.  However, with the new requirement to allow two ADUs 
per lot (and possibly three), the lot coverage maximums in the RE-43, RE-24, R1-14, 
and RE-35 districts have been proposed to be increased by 10%.  The one-story 
height limitation for all buildings on the lot, required to achieve increased lot 
coverage, remains in place.   The revised lot coverage permissions are as follows: 
 
• RE-43 lot coverage increases from 20%/30% if all structures one-story, to 
20%/40% if all structures are one-story. 
• RE-24 lot coverage increases from 25%/30% if all structures one-story, to 
25%/40% if all structures are one-story. 
• R1-14 lot coverage increases from 25%/30% if all structures one-story, to 
25%/40% if all structures are one-story. 
• RE-35 (Subdivision Option) lot coverage increases from 25%/30% if all 
structures one-story, to 25%/40% if all are structures one-story. 
 
CONCLUSION 
The proposed amendment to the Zoning Ordinance, provided in Exhibit A, will bring the 
City into compliance with the requirements of HB 2720.   
 
Staff recommends approval of the changes to the Zoning Ordinance as proposed in Exhibit 
A.

1. 
In zoning districts where accessory dwelling units are a permitted use, one 
ADU is permitted per lot when a single-family detached primary dwelling unit 
is also provided, unless otherwise permitted by the zoning district.  THIS 
SECTION APPLIES TO ACCESSORY DWELLING UNITS WHEN A LOT 
HAVING NO MORE THAN ONE SINGLE-FAMILY DWELLING UNIT IS 
PERMITTED ONE OR MORE ADUS PER THE UNDERLYING ZONING 
DISTRICT. 
2. 
An ADU is not permitted on a lot with a single-family attached dwelling unit, 
a duplex, triplex, or multifamily dwelling units, unless otherwise permitted by 
the zoning district. AN ADU MAY BE EITHER ATTACHED TO OR 
DETACHED FROM THE PRIMARY DWELLING UNIT, SUBJECT TO THE 
FOLLOWING: 
a. 
A MAXIMUM OF ONE ATTACHED ADU MAY BE PROVIDED PER 
LOT.   
b. 
A MAXIMUM OF ONE DETACHED ADU MAY BE CONNECTED TO 
THE PRIMARY DWELLING UNIT BY A PORCH, DECK, COVERED 
PATIO, CARPORT, BREEZEWAY, OR SIMILAR.  
 
3. 
An ADUS  may be either attached to or detached from the primary dwelling 
unit,  ARE subject to the following design guidelines: 
a. 
An attached ADU shall be integrated into the design of the primary 
dwelling unit so that it appears to be part of one single family home, 
rather than a duplex.  This guideline does not prohibit the provision of 
separate entry features. (P) 
b. 
A detached ADU, when visible from adjacent streets, shall be 
constructed with similar and/or complementary materials, design, and 
color(s) as the primary dwelling unit, SHOULD HAVE A 
RESIDENTIAL APPEARANCE IN NATURE AND DESIGN, or as may 
be approved by Historic Preservation for HP zoned or designated 
properties. (P) 
 
Rationale: ADUs are intended be subordinate to the primary single-family 
home and should visually appear as such.  An ADU which looks like a 
second duplex unit, or a second detached primary dwelling unit, does not 
meet this intent. MATERIALS MORE COMMONLY ASSOCIATED WITH 
COMMERCIAL STRUCTURES SHOULD BE AVOIDED.  HOWEVER, 
THESE DESIGN GUIDELINES DO NOT REQUIRE THAT AN ADU 
MATCHES THE EXTERIOR DESIGN, ROOF PITCH, OR FINISHING 
MATERIALS OF THE PRIMARY DWELLING UNIT.
