Corpus Christi requires building permits for retaining walls over 4 feet in height or those that support a surcharge load. Engineered plans from a Texas-registered professional engineer are required for permitted walls.
Retaining walls in Corpus Christi are regulated under the adopted 2021 International Building Code with local amendments effective August 2023. Walls retaining earth that exceed 4 feet in height measured from the bottom of the footing to the top of the wall require a building permit with engineered structural plans. Walls supporting a surcharge such as a driveway, building, or additional soil load also require permits regardless of height. The engineer must be registered in Texas. Retaining walls that also serve as fence structures must meet both the retaining wall structural requirements and the fence height and material standards. Drainage is a significant consideration in Corpus Christi due to the flat coastal terrain and hurricane-season rainfall -- walls must include proper drainage provisions to prevent hydrostatic pressure buildup. The Development Services Department reviews structural plans for compliance. Contact (361) 826-3240 for permit applications.
Unpermitted retaining wall: fines up to $500 per day. Failed structural wall: mandatory engineering evaluation at owner expense. Removal or reconstruction may be ordered.
