Permits & licenses in Williamson County.
Williamson County sits inside Tennessee's two-layer arrangement: the State Fire Marshal's Office holds building code plans review and inspection everywhere it has not delegated them, and here it has — the local codes department issues the permit and runs the inspections. State-owned buildings, schools and licensed daycare facilities stay with the state either way.
- The Williamson County Building Codes Department in Franklin administers the adopted International Codes for the unincorporated county, with building permits and plan review running through the county's Electronic Plan Review System.
- Electrical permits for projects in the unincorporated county come from the State of Tennessee.
- Franklin, Brentwood and Spring Hill are separately approved exempt jurisdictions under the State Fire Marshal's Office, each running its own plans review and inspections.

How it moves
Your package is reviewed against the current Williamson County submission requirements before it's filed — forms, editions, scales, signatures. Then it's tracked in the queue and carried through comments. A resubmittal means the back of the line; the pre-filing review is there to help keep you out of it. The habit comes from volume: the team has processed 400+ permits annually across Maryland, D.C., and Virginia counters.
