East Baton Rouge Parish, LA Fence Regulations: Retaining Walls (2026)

East Baton Rouge Parish regulates retaining walls through Title 8, Building Regulations, the same chapter that governs the rest of the construction code; there is no separate retaining-wall ordinance. Sec. 8:500 sets the baseline: any owner or authorized agent who intends to construct, enlarge, alter or repair a structure must first apply to the building official and obtain a permit. Sec. 8:501(1)(c) then exempts one narrow category from that requirement: retaining walls that are not over four feet in height, measured from the bottom of the footing to the top of the wall.

That exemption disappears the moment the wall supports a surcharge, meaning it carries a load beyond its own retained soil, such as a driveway, structure or sloped fill above it, or if it impounds Class I, II or IIIA liquids, the fire code's flammable and combustible liquid classifications. A wall that crosses the four-foot threshold, or that falls into either exception, needs a permit and must be designed and built to the International Building Code and International Residential Code as adopted and amended by the Louisiana State Uniform Construction Code Council under Sec.

8:200, since neither code exempts retaining walls from its structural provisions once a permit is required. Sec. 8:501 also makes clear generally that an exemption from the permit itself never excuses noncompliance with the underlying building-code standards or any other ordinance. Once permitted, the same examination-of-documents and inspection framework used for the rest of Title 8 applies to the wall as built.
