Marathon County's Conservation, Planning and Zoning Department puts a note on its own permit page that settles the most common question: it does not provide information about building permits under the Uniform Dwelling Code, and directs enquirers to the building code officials for their location.
The department's Regulatory Programs division administers the county's zoning, shoreland, floodplain, airport, private onsite wastewater and mining ordinances. These are enforced county-wide with one exception — comprehensive zoning, which must be adopted by each town before it takes effect there.
This guide covers unincorporated Marathon County. Wausau, Schofield, Rib Mountain, Mosinee and the county's other cities and villages permit their own construction; Wausau holds all-size commercial delegation as a second-class city.
18 towns in, 21 out — but shoreland covers all 39. 18 of the county's towns participate in the county zoning programme, which applies the same districts for regulatory consistency; the rest administer their own general zoning. Shoreland overlay applies in every one of the 39 towns regardless: 1,000 feet from navigable ponds, lakes and flowages, and 300 feet from any navigable stream or river.

What is actually local, and what is not
Construction standards are statewide, and the county disclaims any role in them. Its layer is land: zoning districts where towns have adopted the county programme, shoreland and floodplain overlays everywhere, wellhead protection that can impose greater restrictions than the state agricultural code, and the private sewage programme.
Wisconsin's Uniform Dwelling Code covers one- and two-family homes. Its Commercial Building Code covers public buildings, workplaces and buildings of three or more units. Local ordinances must conform to both. Wisconsin rules

Permit types
Residential permits
A rural house is permitted by the town's building code official under the Uniform Dwelling Code, with state Dwelling Contractor credentials. County work comes first where it applies: a zoning permit in the 18 participating towns, shoreland approval anywhere near navigable water, and a private sewage permit where there is no public sewer.
How Wisconsin contractor licensing works
Wisconsin certifies dwelling contractors and licenses electricians and plumbers at state level (see Wisconsin rules). Marathon County licenses no trades; state credentials govern and the town's building code official verifies them.
Commercial permits
Commercial development in county zoning jurisdiction needs county land-use approval, with rezonings running two to three months through the Environmental Resources Committee and County Board. Building code plan review routes to the state or a delegated municipality — Wausau reviews at all sizes as a second-class city; the county holds no delegation.

Call 1-855-478-4290 →Mechanical work, and where the state reviews directly
Commercial plans above set sizes go to the state for review first (see Wisconsin rules). Wellhead Protection District rules may impose greater restrictions than the state agricultural code where municipal water supplies are involved.
Marathon County permit costs and fees
County fees cover the zoning, sanitary and regulatory programmes and are separate from the town's building permit fee. Time, rather than fee level, is the planning constraint on rezonings.
| Item | Fee or rule |
|---|---|
| County zoning permit | In the 18 participating towns, per the county schedule |
| Rezoning petition | Heard by the Environmental Resources Committee; generally two to three months |
| Private sewage permit | Under the county sanitary ordinance |
| Building permit | Set by the town's building code official |
Shoreland maps are a guide, not a determination. The county cautions that the shoreland overlay maps should be used as a guide, and that navigability determinations may be needed to verify whether shoreland regulations actually apply to a given parcel.
Trade permits and who may pull them
Trades are state-credentialed and permitted at town level; the county's regulatory reach is land, water and wastewater.

Review, corrections and what actually causes delay
The county's own disclaimer is the practical guidance: do not call the county about a building permit. Time risk sits in rezonings, which run two to three months, and in navigability questions on shoreland parcels.
