New Orleans's Building Setbacks & Zoning: The Rules That Matter
Every city handles building setbacks & zoning a little differently. In New Orleans, Louisiana, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Structure Height Limits
Maximum building height is set per district in the CZO. In the Historic Urban Neighborhood Two-Family (HU-RD2) district, the maximum building height is 35 feet. Detached accessory structures in a required yard are capped at 14 feet.
Key details: Set by: CZO district bulk tables. HU-RD2 max height: 35 feet. Accessory in yard: 14 feet maximum. Historic overlay: May further limit height. Relief: Board of Zoning Adjustments.
Exceeding the district height limit requires a variance from the Board of Zoning Adjustments; unpermitted over-height construction faces stop-work orders, fines, and removal.
Lot Coverage Limits
The CZO controls buildout through required open space and impervious-surface limits rather than a single lot-coverage cap. In HU-RD2, front-yard impervious surface is capped at 40%, and detached accessory structures may cover no more than 40% of the required rear yard.
Key details: Control method: Open space + impervious limits. HU-RD2 front impervious: 40% maximum. Rear-yard accessories: 40% of rear yard max. Open space: Planted or permeable hardscape. Basis: CZO Art. 11 & Sec. 21.6.A.
Exceeding impervious-surface or open-space limits is a CZO violation reviewed by the Department of Safety and Permits; relief requires a variance, and non-compliant paving or structures may be ordered removed.
Setback Rules
Required yards (setbacks) are set per zoning district in the CZO. In a Historic Urban Neighborhood two-family district (HU-RD2), the interior side yard for single/two-family homes is 3 feet and the rear yard is 20% of lot depth or 15 feet, whichever is less.
Key details: Set by: CZO district bulk tables. HU-RD2 side yard: 3 feet (SF/2F/3-4 unit). HU-RD2 rear yard: 20% depth or 15 ft, lesser. Front yard: Per build-to line rule. Variances: Board of Zoning Adjustments.
Encroaching into a required yard without a variance from the Board of Zoning Adjustments is a CZO violation; the structure may be denied a permit or ordered removed.
The Bottom Line
New Orleans's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming New Orleans is broadly strict or permissive.
Keep in mind that New Orleans can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
