Summary
A retaining wall in unincorporated Rapides Parish needs a building permit under Sec. 6½-3, and Sec. 24-14(3) waives a separate grading permit only when the wall's excavation is authorized by that valid building permit. Any wall project, permitted or not, still owes ongoing erosion and sediment control under Secs. 24-16 and 24-20.

Full Breakdown
A retaining wall is a "structure" under Rapides Parish's adopted building code, so Sec. 6½-3 requires a building permit from the parish building official before you build, alter or repair one, the same as any other structure regulated under the 2006 International Building and Residential Codes adopted in Sec. 6½-2. The parish's separate grading-permit system treats a permitted wall differently from an unpermitted one: Sec. 24-14(3) exempts "excavation in connection with a building, swimming pool, retaining wall, or other structure authorized by a valid building permit" from needing its own grading permit.
If a wall isn't covered by a building permit, and the excavation for it disturbs an acre or more or is part of a larger site plan, it falls under the grading-permit process in Sec. 24-15, run by the Rapides Area Planning Commission, and the site plan required by Sec. " Whichever track applies, Sec. 24-16 makes clear that a grading-permit exception "does not relieve the owner, developer, contractor, or other legal representative of the responsibility of installing and properly maintaining the proper erosion/sedimentation control measures" tied to the wall's construction, and Sec.
24-20 backs that up with a parishwide duty to keep erosion and sediment from crossing onto an adjoining property, right-of-way or stream. Where a grading permit is required, Sec. 00 for each additional acre, valid for one year under Sec. 24-18.
Violations & Fines
Constructing a retaining wall without the required building permit is a misdemeanor under Sec. 6½-8, fined between $100 and $500 per offense, and the building official may seek an injunction under Sec. 6½-6. If the wall instead falls under the grading-permit track and causes erosion or sediment to cross onto a neighboring lot, right-of-way or stream, that breaches Secs. 24-16 and 24-20 and exposes the responsible party to Chapter 24's $250-per-day first-offense fine under Sec. 24-25.
