Garage conversion rules in Collier County, FL — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Converting a garage into living space in unincorporated Collier County needs a building permit, and adding a kitchen can turn the space into a separate dwelling unit. That is barred in single-family zoning, and renting a converted garage as a second unit is a code violation.
Collier County has no by-right accessory-dwelling ordinance, so a garage conversion is treated as an addition or a guesthouse. Under LDC 4.01.02, a room counts as a kitchen when it has a range, a food-prep sink and counter, or an unexplained 220-volt outlet, any of which can reclassify a conversion as a second dwelling unit. Single-family districts allow only one dwelling unit, and LDC 5.03.03 makes leasing a guest accommodation a violation. You'll need a building permit; if the garage is enclosed, replacement off-street parking must still meet LDC 4.05 requirements. City rules govern inside Naples, Marco Island, and Everglades City.
An unpermitted conversion or an illegal second rental unit is enforced by Collier County Code Enforcement, which can require restoration, deny occupancy, and impose daily fines under Florida Statutes Chapter 162.
