Lewisville TX fence permit rules
In most Lewisville residential zones, fences up to 6 feet in rear and side yards can be built without a permit. Front-yard fences and fences over 6 feet typically require a permit. Call (972) 219-3630 with your address and proposed height to confirm before purchasing materials. Texas has no state GC license requirement.
Texas has no state GC license requirement — any contractor can manage residential projects. TSBPE-licensed plumbers and TDLR TECL-licensed electricians are required for permitted trade work. DFW sits on Blackland Prairie expansive clay soil that swells when wet and shrinks when dry, causing slab movement. All DFW homes are slab-on-grade — no basements. Oncor is the TDU (Transmission and Distribution Utility) in ERCOT's deregulated market for most of the DFW metro; homeowners choose their retail electricity provider. Atmos Energy serves natural gas.
Lewisville is a Lake Lewisville area suburb — some lakefront or waterfront-adjacent properties should check FEMA flood zone status at msc.fema.gov before exterior projects.
DFW's Blackland Prairie clay soil — locally called "black gumbo" — is the dominant fence post engineering factor in Lewisville. The clay swells dramatically when wet (after rain) and contracts hard when dry (summer drought), cycling through significant volume changes across seasons. This movement heaves and tilts fence posts just as reliably as frost heave in northern markets. Posts in concrete at 36–42 inches depth — anchoring through and below the active clay zone — is the standard Lewisville practice. Concrete-set posts at 18–24 inches that might work in moderate climates will rock and lean in DFW clay within a few seasons. Call 811 at least 3 business days before any post-hole excavation.
