When a permit is required

Permit triggers and exempt work for Hamilton County

The reviewed county sources support permit or approval requirements for septic/OSSF matters, subdivision plats, and county-road culvert or entry work. The culvert policy states no culvert may be installed in a Hamilton County roadway, road drainage ditch, or right-of-way without a permit. No clearly documented countywide general building permit requirement for ordinary vertical construction was found.

Note: Important caveat: Even where no general county building permit is documented, a project can still trigger septic or OSSF review, subdivision plat approval, or a county-road culvert or entry permit. Do not assume either a countywide permit requirement or exemption list without confirming directly with county.
