Summary
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.
Detached accessory structures shall be located a minimum of three (3) feet from any lot line, unless otherwise permitted or limited by this Ordinance.
Full Breakdown
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.
Violations & Fines
Unpermitted conversions are code violations subject to fines, red-tag orders, and required restoration or compliance through Safety and Permits.
