La Porte requires building permits for retaining walls over 4 feet in height. Walls over 4 feet must be designed by a licensed professional engineer. Drainage must be managed to prevent water from flowing onto adjacent properties.
The City of La Porte requires a building permit for retaining walls exceeding 4 feet in height measured from the bottom of the footing to the top of the wall. Retaining walls over 4 feet must be designed by a licensed professional engineer and submitted with engineering calculations and construction drawings as part of the permit application. Walls 4 feet or under in height generally do not require a permit but must still comply with setback requirements and property line restrictions. All retaining walls must include proper drainage provisions such as weep holes or drainage pipes to prevent hydrostatic pressure buildup and water damage to adjacent properties. Retaining walls must not redirect stormwater flow onto neighboring properties. Given La Porte's location near Galveston Bay and relatively flat terrain, soil conditions and water table levels should be evaluated during design. Contact the Building Department at (281) 471-5020 for retaining wall permit requirements.
Building a retaining wall over 4 feet without a permit and engineering plans may result in a stop-work order and requirement to obtain a retroactive permit. Non-compliant walls may need to be rebuilt or removed. Walls causing drainage damage to adjacent properties may result in additional enforcement action.
