A Phoenix ADU requires site-planning approval and residential plan review; current zoning can allow multiple ADUs on some single-family lots, but each project remains site-specific.
Phoenix identifies electrical updates, rewiring and additions as permit work, so a residential panel or service upgrade requires an electrical permit and inspection.
Phoenix directs residential fence and wall projects through a fence permit process; fences above seven feet require structural design, while zoning, right-of-way and retaining-wall rules apply at lower heights too.
Phoenix lists an air-conditioner repair or replacement as permit-exempt only when size, capacity and location do not change; other HVAC scopes require permit review.
A like-for-like Phoenix roof repair without new structural components can be permit-exempt; framing, sheathing or other structural changes require permit review.
Phoenix residential rooftop solar requires City permitting; eligible projects may use SolarAPP+ but still need a Phoenix permit, supporting documents, inspection and a separate Fire permit.
Phoenix treats a water-heater replacement by a licensed contractor as permit-exempt, while DIY electric replacement, relocation, gas, venting or system changes can require permits.
