When a permit is required
Permit triggers and exempt work for Oakland County
Septic permits are required for new, replacement, alteration, and repair work described on the county page; general building permit requirements depend on the township or local enforcing agency serving the unincorporated parcel.
Note: No countywide general building exemption list was confirmed for all unincorporated Oakland County parcels because general building administration depends on the specific township or enforcing agency.
