Garage conversion rules in Huntington Beach, CA β sometimes called garage-to-ADU or accessory living unit conversions β govern permits, ceiling height, egress, and parking replacement.
Garage conversions in Huntington Beach require a building permit. California's ADU law streamlined garage-to-ADU conversions, which may not require additional parking replacement.
Converting a garage to living space in Huntington Beach requires a building permit. If converting to an ADU, California state law (Government Code 65852.2) prohibits the city from requiring replacement parking for the converted garage space. The converted space must meet building code habitability standards including egress, ventilation, insulation, and fire separation. Junior ADUs (up to 500 sq ft within existing structures including garages) are also allowed with an efficiency kitchen. Non-ADU conversions must still address parking requirements.
Unpermitted conversions may result in fines, required reversal, or forced compliance with current codes.
