When you need a Garage permit
Building a new attached garage requires building and electrical permits. Attached garages require fire-rated separation from the dwelling (1-hour fire-rated wall and self-closing door per CBC), proper ventilation, and compliance with zoning setbacks and lot coverage limits.
Building a new detached garage requires building and electrical permits. Detached garages are subject to accessory structure requirements, zoning setbacks, and lot coverage limitations. Fire-rated construction may be required if within 5 feet of property lines.
Carports require a building permit as they are considered new structures. Carports must comply with zoning setbacks and may have different requirements than fully enclosed garages. Open sides may be required to qualify as a carport rather than a garage for zoning purposes.
Converting a garage to living space requires building, electrical, plumbing, and mechanical permits. California AB 68 and SB 13 have streamlined garage-to-ADU conversions, eliminating parking replacement requirements and reducing fees. The conversion must meet habitable space requirements including insulation, egress windows, and ceiling height.
