Before You Build in New Orleans, LA: Permit & Rule Checklist (2026)

New Orleans typically requires a permit from the Department of Safety and Permits before installing or replacing a fence, especially when the work involves structural foundations, masonry walls, or any installation in a historic district. Even simple wood or chain-link fences may require a zoning verification to confirm height, location, and material compliance. Historic districts under HDLC and the Vieux Carre Commission require design review on top of the building permit.

Louisiana follows a civil-law tradition rather than common law, and Louisiana Civil Code Articles 673 through 688 govern boundary walls, common fences, and shared enclosures. A wall built on the boundary line is presumed common (jointly owned), and either neighbor can demand contribution to maintenance costs. New Orleans property owners should understand these civil-code presumptions before building, replacing, or repairing a boundary fence, since they differ markedly from common-law rules in most other states.

The New Orleans Comprehensive Zoning Ordinance limits fence heights based on yard location and zoning district. Front-yard fences in most residential districts are typically capped at three to four feet, while side and rear yard fences may rise to six to seven feet. Historic districts impose stricter design review through the Historic District Landmarks Commission and the Vieux Carre Commission, where materials, openness, and historic character all factor into approvals.

All residential swimming pools deeper than 24 inches must be enclosed by a barrier at least 48 inches high with self-closing, self-latching gates that open outward away from the pool. Requirements come from the Louisiana State Uniform Construction Code, which adopts the International Swimming Pool and Spa Code (ISPSC). Permits are issued by the Department of Safety and Permits.

Retaining walls over 4 feet in height (measured from bottom of footing to top of wall) require a building permit and engineered drawings sealed by a Louisiana-licensed professional engineer. Permits are issued by the Department of Safety and Permits. Walls in drainage servitudes or near the levee system face additional review by the Sewerage and Water Board and the Orleans Levee District.

Above-ground pools in New Orleans need a building permit when water depth exceeds 24 inches and must meet the same IRC Appendix G barrier rules as in-ground pools. The Comprehensive Zoning Ordinance restricts pools to rear yards in most residential districts, and HDLC or Vieux Carre review can limit installations in historic neighborhoods.

Hot tubs and spas in New Orleans are regulated as pools when water depth exceeds 24 inches, requiring building and electrical permits, GFCI protection, and IRC Appendix G barrier compliance. Lockable ASTM F1346 covers are the most common way to satisfy the safety barrier requirement for portable units.

New Orleans pool barriers must comply with the International Swimming Pool and Spa Code as adopted statewide: a 48-inch minimum barrier fully enclosing the pool, with self-closing self-latching gates opening outward. Historic districts require HDLC or VCC review of fence design and materials, often limiting modern picket or chain link in favor of traditional wrought iron or wood.

New Orleans residential swimming pools must comply with the Louisiana State Uniform Construction Code, which adopts the International Residential Code (IRC) Appendix G barrier requirements. The City Department of Safety and Permits enforces fencing, gate, and alarm rules through the building permit process, and Vieux Carre or HDLC review applies to historic neighborhoods.

All in-ground and permanent above-ground swimming pools in New Orleans require a building permit from the Department of Safety and Permits. Pools must comply with the Louisiana State Uniform Construction Code, which incorporates the International Swimming Pool and Spa Code. Historic district properties require HDLC or VCC review, and high flood zones impose additional design constraints.

Converting a garage into living space in New Orleans requires building, electrical, plumbing, and mechanical permits and must meet ADU standards if the new space is a separate dwelling unit. Historic district approval and FEMA flood elevation rules often apply, particularly for the city's many traditional carriage houses.

New Orleans permits accessory dwelling units, called auxiliary or accessory dwelling units, under the 2015 Comprehensive Zoning Ordinance. ADUs are allowed in most single- and two-family districts subject to size, height, and design standards, and historic district commissions add architectural review.

Sheds in New Orleans up to 200 square feet and one story generally do not require a building permit but must still meet zoning setbacks and historic district review where applicable. Larger sheds or those with electrical or plumbing connections need permits from the Department of Safety and Permits.

New Orleans does not have a dedicated tiny home ordinance, so small dwellings on permanent foundations are regulated as either single-family homes or accessory dwelling units under the CZO. Tiny homes on wheels are treated as recreational vehicles and may not be used as permanent residences in residential zones.

Carports in New Orleans are accessory structures regulated by the Comprehensive Zoning Ordinance and require building permits when attached to the dwelling or exceeding 200 square feet. Setback, height, and lot coverage rules apply, and historic district commissions strictly limit visible front-yard carports.

Open burning of trash, leaves, brush, and construction debris is generally prohibited within Orleans Parish under both city ordinance and Louisiana Department of Environmental Quality air-quality regulations. Limited exceptions exist for small recreational fires, outdoor cooking, and ceremonial fires, but residential leaf or yard-waste burning is not allowed in the urbanized parish. Violations can trigger fire department response, citations, and LDEQ enforcement.

Recreational fires in New Orleans are regulated under Ch. 26 Fire Prevention and the Louisiana State Fire Marshal's adoption of the International Fire Code, requiring distance from structures, supervision, and immediate extinguishment when ordered.

Heritage live oaks (Quercus virginiana) and other significant trees on public property and in many historic districts are protected under the New Orleans Comprehensive Zoning Ordinance Article 23 and Department of Parks and Parkways rules. Trimming a heritage live oak generally requires a permit from Parks and Parkways. Routine trimming of private trees that are not designated heritage specimens is allowed without a permit.

New Orleans does not impose routine outdoor watering restrictions because the Sewerage and Water Board draws from the Mississippi River, an effectively unlimited supply. Restrictions appear only during emergencies such as boil-water advisories or major main breaks. Stormwater concerns dominate local water policy, not drought.

Removal of any tree on the public right-of-way (including the neutral ground and the strip between sidewalk and curb) requires a permit from the New Orleans Department of Parks and Parkways. Heritage live oaks and protected trees on private property in certain districts also require permits. Unauthorized removal can trigger fines and a replacement obligation calculated from the appraised value of the lost tree.
