Full Breakdown
' A wall over four feet, or any wall that carries a surcharge, falls outside the exemption and requires a permit under the general rule in § 3½-123(a), which obligates an owner or authorized agent to apply to the building official and obtain a permit before constructing a structure regulated by the parish's adopted codes. ' A retaining wall requiring a permit must go through the application process in § 3½-123(c), including construction documents, and the building official may require documents from a registered design professional under § 3½-124(a) where special conditions exist. This rule applies only within the unincorporated parish; Monroe, West Monroe, and Sterlington set their own retaining-wall standards inside city limits.
Violations & Fines
Building a retaining wall over four feet, or one that supports a surcharge, without a permit is a misdemeanor under § 3½-111, punishable by a fine of not less than one hundred dollars and not more than five hundred dollars for each offense, and the building official may seek to enjoin the unpermitted work under § 3½-109.
