Phoenix Zoning & Land Use Guide
Key Zoning Facts
Phoenix Zoning Overview
Phoenix, the fifth-largest city in the United States, administers its zoning through the Planning and Development Department. The city's zoning ordinance is contained in Chapter 6 of the Phoenix City Code, establishing a comprehensive framework of residential, commercial, and industrial districts. Phoenix's rapid growth has made land use planning a critical function, with the General Plan 2015 (updated periodically) providing long-range guidance.
The city's land use reflects its Sunbelt character: expansive low-density residential development, automobile-oriented commercial corridors, and emerging mixed-use nodes along the Valley Metro light rail line. Phoenix has been transitioning toward more transit-oriented development and infill strategies to reduce sprawl and make efficient use of existing infrastructure.
The desert environment presents unique land use challenges including extreme heat, flash flood management, and water conservation. Phoenix's zoning includes provisions for desert-sensitive design, shade requirements, and water-efficient landscaping standards.
Key Zoning Districts
Phoenix uses a detailed zoning system with single-family residential districts (R1-6, R1-8, R1-10, R1-14, R1-18), multi-family districts (R-2 through R-5), commercial districts (C-1 through C-3), and industrial districts. The city has also adopted transit-oriented and walkable urban zoning districts to support light rail development.
ADU Regulations
Phoenix adopted ordinances permitting ADUs in single-family residential zones, making it one of the more progressive Arizona cities on accessory dwelling units. Arizona has no statewide ADU law, so Phoenix's local provisions govern ADU development. ADUs must meet size, height, and setback standards, and one off-street parking space is required.
Development Process
Building permits are processed through the Planning and Development Department. Phoenix offers online permitting services for many project types. The Zoning Administrator handles administrative approvals, while the Board of Adjustment reviews variances and the Planning Commission considers rezoning applications.
