5 project guides · 4,713 permits in 12 months · New Orleans Department of Safety and Permits
In New Orleans, residential permits are issued by the New Orleans Department of Safety and Permits. Our counts use the city's NOLA Permits dataset. Short answers for each project we cover:
- Roof replacement: Yes (50%+). For one- and two-family homes, Ordinance 30,235 MCS requires a separate residential re-roofing permit when 50% or more of the roof is replaced. Replacing less than 50% is exempt unless other criteria require a permit. Historic districts (HDLC and VCC) need extra review.
- AC or furnace replacement: Yes. New Orleans requires a mechanical permit to install, repair, replace or alter air conditioning, electric or gas furnaces and heaters, or gas lines. An HVAC permit can only be pulled by a holder of a Class A City of New Orleans Mechanical A/C license.
- Solar panel installation: Yes. Rooftop solar in New Orleans is permitted as an electrical permit, which only a contractor with a Class A City of New Orleans electrical license can obtain. Since March 1, 2025, applications need an approved SolarAPP+ plan review.
- New fence: Often no. Fences up to 7 feet high that comply with the Comprehensive Zoning Ordinance don't need a building permit in New Orleans; masonry walls used as fences are exempt only up to 3 feet. Properties in historic districts may still need HDLC or VCC approval.
- New deck or porch: Usually yes. Only small freestanding decks are exempt in New Orleans: uncovered residential decks no larger than 200 sq ft, no higher than 30 inches above grade, not attached to the house and not serving an exit door. Replacing deteriorated unenclosed, uncovered porches and steps 5 feet or less above grade is also exempt.

How to Use These Louisiana Guides
Start with the city that issues permits for your address. If you live outside city limits, your county or township usually handles permits instead, and its rules can differ from the city pages here. Each project guide quotes the official rule, lists any fee the city publishes, and links to the source so you can confirm it before you start work. Permit counts show how often each kind of job is permitted locally, and median days to issue show how long a typical application took over the last 12 months. Rules and fees change, so treat the official source as final and call the permit office if your project is unusual.
