Garage conversion rules in Phoenix, AZ — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Garage conversions in Phoenix require building permits and must meet residential building code standards for habitable space. Converted garages may qualify as ADUs under HB 2720. The conversion must include proper insulation, egress windows, electrical, ventilation, and plumbing (if applicable). No additional replacement parking is required under state ADU law.
Phoenix allows garage conversions to livable space under the Phoenix Zoning Ordinance (Chapter 6), but the converted area must meet residential building code requirements including proper egress windows, insulation to handle extreme desert heat, and ventilation standards. A building permit from the City of Phoenix Planning and Development Department is required before any conversion work begins, and inspections must be passed for electrical, plumbing, and structural modifications. Converting a garage eliminates required off-street parking, so the property must still meet the minimum parking requirements for the zoning district—typically two covered spaces for single-family homes. Contact the Planning and Development Department at (602) 262-7811 for permit applications and zoning verification before starting a garage conversion project.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Phoenix code enforcement directly for current fines, enforcement procedures, and hearing options.
