Garage conversion rules in Duval County, FL β sometimes called garage-to-ADU or accessory living unit conversions β govern permits, ceiling height, egress, and parking replacement.
Garage conversions in Duval County require a building permit and must retain required off-street parking. Converted space often regulated as ADU under Β§656 and FL Β§163.31771.
Converting a garage to habitable living space requires full building permit review: structural upgrades to slab/walls, insulation to FBC energy code, egress windows, smoke/CO alarms, HVAC extension, and electrical upgrades. Off-street parking requirements (typically 2 spaces for single-family) must still be met β either via driveway/carport or new parking area. If the converted space functions as a separate unit with its own kitchen and bathroom, it is an ADU and must meet ADU standards. Jacksonville Building Inspection Division issues permits; multiple trade inspections required.
Unpermitted conversion: must restore garage or obtain after-the-fact permit at 2x fee. Potential insurance and resale complications.
