Mansfield, TX Fence Regulations: Height Limits (2026)

The Mansfield Unified Development Code regulates fence heights across residential and commercial zoning districts. Single-family residential front-yard fences are capped at 4 feet in height to preserve streetscape visibility along major corridors like US-287 Business, Broad Street, Main Street, and Matlock Road, and in interior subdivision streets. Side-yard and rear-yard fences may reach up to 8 feet. On corner lots, the side yard that faces the street is treated as a front yard, meaning the street-facing side is limited to 4 feet so that sight lines at intersections are preserved. Visibility triangles at driveways and street corners must remain clear of solid fencing or vegetation over 3 feet. Fences exceeding 8 feet, masonry fences, brick columns over 4 feet, and retaining walls over 4 feet measured from grade to top require engineered designs stamped by a Texas-registered professional engineer and a building permit from Mansfield Building Services. Fence height is measured from the higher side grade. HOA covenants in Walnut Creek, Mira Lagos, South Pointe, and M3 Ranch routinely tighten the city rules and dictate style, stain, and finished side placement.
