Carrollton TX window replacement permit rules
City of Carrollton Building Inspections does not typically require a permit for window replacement when the window fits within the existing rough opening and no structural modifications are made. A permit is required when the rough opening is enlarged, the wall structure is modified, or the window change affects an egress opening. Apply via carrolltontx.gov. Texas requires no GC license. Call (972) 466-3060 to confirm for your specific scope.
Carrollton's CZ2A climate makes window selection an energy efficiency decision as much as a comfort decision. U-factor of 0.30 or better is recommended for code compliance and energy performance in CZ2A. Solar Heat Gain Coefficient (SHGC) of 0.25 or lower is recommended for Carrollton's intense cooling season — lower SHGC reduces solar heat gain through south- and west-facing windows, directly reducing air conditioning load. ENERGY STAR certified windows for the Southern Climate zone meet these specifications.
