ADU Permit Requirements in Wabeno, WI
Wabeno is an unincorporated town (pop. ~1,167) in Forest County, far northern Wisconsin (Nicolet National Forest, Wolf River area). Wisconsin uses a split AHJ model for small towns: Forest County Zoning & Sanitary issues land use (zoning), shoreland, floodplain, and POWTS (septic) permits and administers the county's sanitary, shoreland, and zoning ordinances. UDC (1-2 family dwelling) building permits and inspections are required under Wisconsin Uniform Dwelling Code (SPS 320-325) and must be performed by a state-certified UDC inspector contracted by the Town. The Town of Wabeno Clerk (715-850-1127, 4473 North Branch St, Wabeno, WI 54566, Tu/Wed/Thu, hours vary) issues local permit applications and can provide the current UDC inspector contact (verify before each project; Forest County is not on the DSPS commercial inspection delegation list as of May 2026). Commercial inspections in this area default to Wisconsin DSPS (608-266-2112). Climate considerations: ASCE 7 ground snow load ~60 psf (highest in WI), Climate Zone 7, frost depth 50+ inches, WI DNR shoreland zoning NR 115 applies within 1,000 ft of lakes or 300 ft of rivers/streams, floodplain NR 116, navigable waters review for any work near Wolf River or area lakes.
