Carrollton TX electrical permit rules
Carrollton's building department requires electrical permits for circuit additions, panel upgrades, service capacity changes, and new wiring. Apply via carrolltontx.gov. TDLR TECL-licensed electricians (tdlr.texas.gov) must perform permitted electrical work. Texas has no state GC license requirement. Call (972) 466-3060.
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.
Carrollton straddles Dallas, Denton, and Collin counties — confirm your address's county for permit jurisdiction if near a county boundary.
In ERCOT's deregulated market, the Oncor TDU owns the delivery infrastructure — poles, wires, meters. For service-entrance work, capacity upgrades, or solar interconnection, Oncor (1-888-313-4747 / oncor.com) is the correct contact regardless of which retail provider bills you. Start Oncor contact the same day as the city permit application. Atmos Energy handles natural gas separately (1-888-286-6700).
Panel capacity is an increasingly relevant issue across DFW as EV chargers and heat pumps get added. Many DFW suburban homes were built with 150–200A panels, but homes built before 2000 may have 100A service. A TECL electrician should assess panel capacity before adding high-draw circuits.
