Do I need a permit for interior remodeling in Katy?
Yes. In Texas, interior remodeling generally requires a permit, and Katy is no exception.
Cosmetic work such as paint and flooring is generally exempt, but moving walls, plumbing, or electrical requires a permit in most Texas cities, with separate trade permits for the affected systems. Exemptions are narrower than homeowners often assume and are set locally, so confirm scope with your city building department before starting. Katy's Permit and Building Services page says remodeling, and any work involving the addition or removal of walls, requires a building permit. Katy's fee schedule charges $15 for a single-family build-out that adds no square footage (Appendix A, Sec. A4.001(b)(2)(I)), and the city's application lists a remodel of an existing structure at $52.50 total with plan check and application fees. Katy's building permit application states that separate permits are required for electrical, plumbing, air conditioning and heating, flatwork and irrigation work.
