Hancock County
As the county government, Hancock County is generally the likely starting point for building and zoning permits on property located in unincorporated areas — that is, land not within any incorporated city, village, or town boundary. This is a routing starting point, not a permit determination: incorporated municipalities within Hancock County typically issue their own permits independently, and a township or intergovernmental agreement may also affect who issues the permit.

Data sources
Confirm locally before you build
- A postal city or ZIP code does not establish legal jurisdiction — municipal and county boundaries can differ from mailing addresses.
- Intergovernmental agreements, delegated county permitting, or township building authority can change which office actually issues the permit.
- Separate permits may still be required for fire protection, septic/well or other health-department review, and driveway or road/right-of-way work.
