Start with the county, then confirm the parcel’s actual jurisdiction.

This directory is organized around county-equivalent authorities, but a county record does not automatically mean the county issues every permit. Incorporated cities, townships, boroughs, tribal authorities, fire districts, and state agencies may control portions of the approval path. Open the county profile, review the jurisdiction status, and call the listed agency when the property sits near a municipal boundary or has a specialized occupancy.
