Keller, TX Fence Regulations: Retaining Walls (2026)

Under Keller Code Chapter 6 and the adopted 2021 International Residential Code, any retaining wall exceeding 4 feet measured from the bottom of the footing to the top of the wall requires a building permit from Keller Building Inspections. Structural drawings must be stamped by a Texas-registered professional engineer and submitted with a drainage plan showing how stormwater will be managed. Keller sits atop the Blackland Prairie and Grand Prairie soils transition, where expansive clays common across the northern DFW metroplex swell and shrink seasonally; engineered designs must account for lateral earth pressure, drainage behind the wall, and long-term seasonal movement. Walls shorter than 4 feet still require compliance with grading and drainage rules and cannot divert water onto adjacent properties or public rights-of-way. Retaining walls may not encroach on public utility easements without written consent from the utility provider. Terraced walls separated by less than the height of the lower wall are generally treated as a single taller wall for permit purposes. HOAs in newer Keller subdivisions often impose additional color and facing material requirements, and many prefer split-face block or natural stone veneers over poured concrete.
