Garage conversion rules in Lake County, FL — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Lake County's LDR has no stand-alone 'garage conversion' rule. Converting a garage into separate living quarters is treated as creating an Accessory Dwelling Unit — one per lot, owner-occupied, size-capped, and permitted under the Florida Building Code. A conversion into more of the main home simply needs a building permit.
There is no dedicated garage-conversion section in the Land Development Regulations. If the converted space becomes a self-contained dwelling with its own entrance, kitchen and bath, LDR Sec. 10.01.03 applies: it is an Accessory Dwelling Unit, limited to one per lot, subject to the recorded owner-occupancy covenant, size-capped at 1,200 sq ft or 70% of the home, and it triggers impact fees. The LDR also flags a separate utility meter, separate address, breezeway connection, or Florida Building Code dwelling status as factors that make added space an ADU. Any conversion requires a building permit and must meet Florida Building Code egress, electrical and ventilation standards. Inside incorporated cities, city zoning controls.
An unpermitted conversion, or one that creates a second dwelling without meeting ADU standards, is a building and LDR violation subject to Code Enforcement action under Chapter 8; penalties reach $500 or 60 days jail (Sec. 1-6).
