Zoning & ADU Rules in Phoenix
Phoenix is one of the most ADU-accessible cities in the US following HB 2720. The city’s dedicated ADU program launched in 2026 streamlines applications with pre-approved plan types — reducing permitting timelines significantly versus a custom permit submission.

| Setbacks | 5 ft minimum from side and rear property lines. 5 ft separation from any other structure on the same lot. Front setback matches primary home. |
| ADU permits | Phoenix Development Services Dept. Phoenix launched a dedicated ADU program in 2026 with pre-approved plan types to accelerate permitting. Online portal available. |
| THOW placement | THOWs classified as RVs in Phoenix city limits — must be in a licensed RV park or manufactured home community. Cannot be parked on a standard residential lot as a primary dwelling. |
| Park model ADU | HB 2579 allows RVIA park models (<400 sq ft) as ADUs when placed on a foundation and meeting setback rules — eligible for standard ADU permit. |
