Do I need a permit for hvac replacement or installation in Willis?
Yes. In Texas, hvac replacement or installation generally requires a permit, and Willis is no exception.
Replacing or relocating HVAC equipment requires a mechanical permit in most Texas cities, and many issue same-day express permits for like-for-like changeouts. Changing equipment location or adding electrical or gas connections can add trade permits and inspections. Confirm the scope with your local building department. Willis permits are handled by the Willis Building Permits and Inspection Division, reachable on 936-856-4611 at https://www.ci.willis.tx.us/168/Building-Permits-Inspections. Its online permit portal is https://app.govwelltech.com/willis. Whether your address sits inside the Willis city limits matters more in Texas than in most states. Texas counties generally do not issue residential building permits, so for property in Montgomery County outside any city there is often no building permit to pull, and a builder follows a separate notice-and-inspection process instead. Confirm which office has jurisdiction over your address before you start. A change-out is normally a mechanical permit, and gas fired equipment usually adds a second permit and a pressure test.
