Hidalgo County has no zoning and adopts no county building code, so it sets no county retaining-wall height or permit rule in unincorporated areas. Structural safety is governed by engineering practice and, in mapped floodplains, by county floodplain rules. Inside a city, that city's building code and permit apply.
Because Texas counties cannot adopt a general building code and have no zoning authority, Hidalgo County sets no retaining-wall height limit and requires no county permit for one in the unincorporated county. There is no county standard like a city's 'permit over 4 feet' rule. That does not remove the owner's duty to build a safe wall: tall walls, or walls holding a surcharge or slope, should be engineered, and a failing wall can create civil liability. A wall in a flood hazard area may require a county floodplain development permit for the fill or drainage, and subdivision covenants may govern grading. Inside a city, that city's building code typically requires a permit above a set height.
The county issues no retaining-wall citation in unincorporated areas because it has no wall code. Unpermitted floodplain fill or a wall altering drainage can violate county floodplain rules and require correction. City wall violations are enforced by that city.
