Garage conversion rules in Glendale, AZ — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Converting a garage to living space in Glendale requires a building permit and must comply with the International Residential Code as adopted by the city. The conversion must meet habitable room standards including egress windows, insulation, electrical, and plumbing. Replacement off-street parking may be required depending on the zoning district. Garage conversions may also be subject to ADU regulations if the space becomes a separate dwelling unit.
Glendale's building code (Chapter 9) and Unified Development Code (Chapter 35) govern garage conversions. A building permit and plan review are required before any conversion work begins. The converted space must meet all habitable room requirements under the International Residential Code, including proper egress, ventilation, ceiling height (minimum 7 feet), and electrical outlets. If the conversion eliminates required off-street parking spaces, the property must provide replacement parking elsewhere on the lot in compliance with zoning requirements. If the garage is being converted into a separate dwelling unit, ADU regulations apply (max 1,200 sq ft, same setbacks as primary dwelling). The city's Development Services division reviews all garage conversion applications.
Unpermitted garage conversions may result in code enforcement citations, fines, and orders to restore the garage to its original condition or obtain proper permits.
