Building Permits
Inside Granbury City Limits, Every Trade Needs Its Own Permit
The line between city and county really matters here. Out in unincorporated Hood County there's no general home-building permit, but the moment a project sits inside the City of Granbury, you're under city rules run out of the inspections office at 116 W. Bridge St. Permits, document uploads, inspection requests, and status tracking all go through the city's OpenGov portal rather than a paper window.
Granbury doesn't lump the trades together: the mechanical, electrical, and plumbing subcontractors each apply for their own individual permit, and only contractors and subs already registered with the city can pull one at all. Even a new driveway approach or a stretch of city sidewalk needs a registered, permitted, inspected contractor. It's not a do-it-yourself afternoon.
Sort the registration out before anyone shows up with tools. If you're not sure whether your lot is inside the city or out in the county, the inspections office at 817-573-1114 can tell you which set of rules you're actually under.
