Approval Timeline
Simple trade permits and minor residential repairs may be issued the same day to 5 business days if complete.

Commercial tenant build-outs and new commercial buildings often take 4 to 10+ weeks depending on fire, accessibility, mechanical, life-safety, and zoning complexity. Incomplete plans, HDLC/VCC review, variances, or flood elevation issues can extend the timeline.

New construction, substantial improvements, and projects in flood hazard areas often require an elevation certificate. Commercial projects usually require code analysis, occupancy classification, occupant load, egress plans, accessibility details, fire-rated assembly details, and sprinkler/fire alarm information where applicable.
Zoning Information
New Orleans uses a Comprehensive Zoning Ordinance with base zoning districts, overlays, use standards, dimensional standards, parking rules, and design standards. Residential, commercial, mixed-use, industrial, neighborhood business, historic, and special purpose districts can significantly affect what may be built. Historic districts, local landmarks, the French Quarter, neighborhood conservation districts, short-term rental rules, and conditional uses may trigger separate approvals before a building permit can be issued.

Small residential repair permits may be roughly $60 to $250. Larger renovations commonly range from a few hundred dollars to $1,500+. New homes and major additions may run about $1,000 to $4,000+ depending on valuation and required reviews. Commercial permits can range from several hundred dollars to many thousands of dollars for larger projects.
Engineering Requirements
