Do I need a permit for kitchen remodel in Dallas County (Unincorporated)?

It depends. Whether kitchen remodel needs a permit in Dallas County (Unincorporated) comes down to the details of your project.

Texas Occupations Code 1301.551 requires every city of more than 5,000 people to require a permit before plumbing work. Replacing a kitchen faucet or a garbage disposal is a listed exception, but moving a sink or adding a fixture is not. Texas defines plumbing to include piping that supplies gas (Occupations Code 1301.002), so moving or adding a gas line for a range is plumbing work that needs a licensed plumber unless the homeowner does it in their own homestead. Cabinets, countertops, and similar finish work are exempt under Section R105.2 of the 2012 International Residential Code that Texas adopts. New appliance circuits are electrical work that requires a TDLR-licensed electrician unless an exemption in Occupations Code 1305.003 applies. This remodel moves walls, plumbing or gas lines, or adds electrical circuits. Replacing cabinets, counters and appliances in place is the part of a kitchen remodel most often exempt; layout and trade work are not. Each trade normally needs its own permit and rough-in inspection before walls are closed, and removing a load bearing wall usually needs a beam detail or engineering. Gas line changes are work many places restrict to licensed gas fitters or plumbers, and a pressure test is commonly part of the inspection.
