Report to the Planning and Zoning Commission
Prepared by the Maricopa County Planning and Development Department
Case:
TA250001 – Maricopa County Zoning Ordinance Update
Date:
June 12, 2025
Supervisor Districts:
All
Applicant:
Staff-initiated
Request:
Update the Maricopa County Zoning Ordinance 
 
Support/Opposition:
None known
Recommendation:
Initiate and Approve 
Proposed Amendment:
This item is being processed through the County’s Enhanced Regulatory 
Outreach Program (EROP).  The Maricopa County Zoning Ordinance was 
originally adopted by the Board of Supervisors in 1969.  It serves as the 
primary regulatory instrument to manage growth and development in the 
unincorporated parts of the County.   The Zoning Ordinance is an essential 
tool to implement the broader land use goals of the Maricopa County 
Comprehensive Plan.   
Although the ordinance has been amended multiple times over the years, 
the County is embarking on a comprehensive update and modernization of 
the Ordinance to better serve current and future citizens.  When completed, 
a new reformatted ordinance will focus on clarity, accessibility and user 
friendliness. Duplicative, conflicting or confusing language will be 
removed; and illustrations, graphs, and charts will be added to clarify 
standards and procedures. Additionally, changes to the Zoning Ordinance 
will include new standards and incentives that advance housing 
opportunities for the County. Upon adoption by the Board of Supervisors, 
the updated Zoning Ordinance will be a more useful and effective tool for 
directing future growth and development in unincorporated areas of the 
County. 
Staff introduced the update at the May 22, 2025 ZIPPOR meeting. The 
Commission is now being asked to formally initialize the Zoning Ordinance 
update in anticipation of future hearings at the end of the year.  
Discussion
1.
Throughout 2023 and 2024, Planning staff conducted an internal review of all chapters of the 
Zoning Ordinance.  The review was provided to Matrix Design Group, a consultant hired in early 
2025 to assist the County with developing a new and reformatted Zoning Ordinance

In fulfillment of EROP, public stakeholder meetings are scheduled for June 5, 2025, and August 
28, 2025, at which time the public will have opportunities to comment on future changes to the 
ordinance.  Staff is presenting a summary of the first stakeholder meeting at the June 12 P&Z 
meeting.  
3.
A Task Force met with staff and consultants at two meetings in May to consider new ideas and 
approaches in the interest of modernizing and improving the Zoning Ordinance.   The Task Force 
will meet again this month, July and possibly in August before a new Zoning Ordinance draft is 
presented.
4.
The public may comment and sign up for updates to the Zoning Ordinance Update by accessing 
the County’s webpage MCZO Update, or by submitting public comments on the County’s EROP 
web page Regulatory Process.
Next Steps: 
5.
Staff recommends the Commission adopt a motion to initiate and approve TA250001 for 
consideration at a future Planning and Zoning Commission hearing.
