Retaining walls over 4 feet in height (measured bottom of footing to top) require a permit and engineered plans in North Richland Hills, per the adopted International Building Code.
North Richland Hills follows the 2021 International Residential Code (IRC) Section R404, which requires engineered design and a permit for any retaining wall exceeding 4 feet from the bottom of the footing to the top of the wall, or any wall supporting a surcharge such as a driveway or pool. Smaller walls under 4 feet can be built without a permit but must still comply with drainage, setback, and fence rules if combined with a fence above them. NRH Planning and Inspections reviews wall plans through the eTRAKiT portal; engineered submittals need a Texas-licensed professional engineer's seal. Walls on steep lots near Walker Branch and Big Fossil Creek need special drainage analysis because of FEMA floodplain mapping. Rockery and boulder walls, block walls, and poured concrete are all acceptable if engineered. Failure to obtain a permit can result in stop-work orders and removal. Call (817) 427-6300 for pre-application review.
