Garage conversion rules in Jefferson Parish, LA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Converting a garage in unincorporated Jefferson Parish is a zoning and building matter under Chapter 40. Turning an accessory garage into separate living quarters requires the district to allow an additional dwelling unit; converting an attached garage into living space needs permits and must keep required off-street parking.
Jefferson Parish's Comprehensive Zoning Ordinance (Ch. 40) treats a private garage as accessory to the dwelling (Sec. 40-743). Enclosing or converting it changes the building's habitable area, so you need building permits and continued compliance with the district's required off-street parking, floor-area, setback and lot-coverage rules. A detached garage cannot become an independent rental unit unless the district permits a second dwelling. Work in incorporated cities (Kenner, Gretna, Harahan) follows that city's code instead.
Unpermitted conversions and loss of required parking are zoning/building violations; the parish may order restoration, deny occupancy and impose fines.
