Garage conversion rules in Orleans Parish, LA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Converting a garage into living space is a change of use regulated by the CZO. Converting it to a separate dwelling is treated as an accessory dwelling unit, so it must meet the accessory-structure standards and the ADU use standard, plus a building permit and off-street parking review.
New Orleans has no standalone garage-conversion ordinance; the CZO governs by treating the result as either added living area of the principal home or a new accessory dwelling unit. As a detached accessory structure, a converted garage in a required yard is limited to 14 feet in height and 3-foot lot-line setbacks under CZO 21.6. Converting to a rentable unit triggers the ADU use standard, minimum dwelling requirements, and off-street parking rules, and the work needs a building permit and inspections from Safety and Permits. Historic-district (VCC/HDLC) properties need additional design approval.
Unpermitted conversions are code violations subject to fines, red-tag orders, and required restoration or compliance through Safety and Permits.
