Gretna, LA Building Safety: Building Inspections (2026)

Section 10-45 lays out the city's building-inspection framework in Chapter 10, Article II, Division 2. Before a building permit issues, the building official can examine any building or service system named in an application to install, enlarge, alter, repair, move, demolish, or change occupancy, and can periodically re-inspect buildings and service systems required to stay in compliance. When materials or assemblies are manufactured outside the city, the building official can inspect them at the point of fabrication, with the cost borne by the party wanting to use the materials here; the building official can also accept certification from an approved third-party testing agency instead.

Every job that receives a permit or filing gets periodic inspection, and every building, structure, or service system gets a final inspection once work is complete, before a certificate of completion issues. No one starts permitted work until the permit is issued and the building permit placard, protected from weather and kept in good condition, is conspicuously posted where the building official can observe it; that posting authorizes the building official onto the premises to perform required duties, and it stays up until the certificate of completion is issued.

Residential home improvement contractors can post a job-site sign between two feet by two feet and two feet by three feet. For every new building, a certified form elevation certificate and a certified site plan showing all building setbacks go to the building section before the slab inspection is scheduled; no foundation inspection happens until the building official certifies the elevation and setbacks match the code, and a certified slab elevation certificate is due within 21 days of the concrete pour. S. 24 with the Louisiana Uniform Construction Code Council and the city, per § 10-39(d), can perform some construction inspections the city accepts, though the city is never required to accept them in place of its own building department inspections.
