Most Wisconsin counties tell you the town issues the building permit. Eau Claire County does not: its Land Use Controls Division administers and enforces building and construction regulations, the shoreland protection overlay district and the zoning code for the unincorporated county — and issues the building permits itself, through a county building inspector.
The division operates from the Government Center Courthouse on Oxford Avenue, handling building permits alongside airport zoning, conditional use permits, land divisions, land use permits, non-metallic mining, shoreland regulations, rezoning and variances and appeals.
This guide covers unincorporated Eau Claire County. The City of Eau Claire and the City of Altoona permit their own construction — Eau Claire under a small-commercial delegation granted in March 2025 — and the county publishes a permitting authority lookup tool because most properties are not under county authority.
The county is the building department here. Unlike its neighbours, Eau Claire County issues building permits directly for unincorporated areas through the Land Use Controls Division, with a county building inspector handling inspections. The county's own first step is nonetheless to verify authority: most properties sit in a city, village or town rather than under county jurisdiction, and the county publishes a lookup tool for exactly that.
What requires a building permit in Eau Claire County?
Wisconsin splits construction into two statewide instruments, and neither one is a city invention. One- and two-family homes run on the Wisconsin Uniform Dwelling Code (SPS 320 to 325), a code Wisconsin wrote for itself — the state never adopted the International Residential Code, so IRC chapter references from other states simply do not apply here. Everything that is a public building or a place of employment, including any residential building of three or more units, runs on the Wisconsin Commercial Building Code (SPS 361 to 366), which moved to the 2021 I-codes effective September 1, 2025; plans submitted on or after November 1, 2025 must comply with the 2021 editions. Under Wis. Stat. 101.65(1c) and 101.02(7r)(a), Eau Claire County may not enforce different technical standards — local ordinances must strictly conform to the state codes.
Typically permit required
- Building permits from the county for new one- and two-family dwellings, including decks serving an exit
- Additions that increase the physical dimensions of a dwelling, including decks serving an exit
- Alterations to the dwelling structure or to its plumbing, heating or electrical systems
- New or re-wired electrical services for one- and two-family dwellings, and electrical wiring in detached residential, commercial or agricultural buildings
- Land use, shoreland, conditional use, rezoning and land division permits
- Erosion control, stormwater management and sanitary permits under the county's programmes
Often exempt
- Re-siding, reroofing, window and door replacement, finishing interior surfaces, cabinetry installation, and non-structural repairs deemed minor by the building inspector
- Major equipment replacements such as furnace, water heater or air conditioner
- Normal repairs of HVAC, plumbing and electrical equipment — replacing switches, receptacles, light fixtures and dimmers
- Buildings used for farming — exempt from the state code under Wis. Stat. 101.05(5), with farming defined by DSPS rule; a produce stand stays exempt only while the farmer raised substantially all of what it sells
- Primitive rural hunting cabins — carved out of municipal jurisdiction by Wis. Stat. 101.65(1g)
- Bed-and-breakfast establishments as defined by statute (Wis. Stat. 101.05(2))
What is actually local, and what is not
The technical standards are the statewide Uniform Dwelling Code and Commercial Building Code, as everywhere in Wisconsin. What is unusual is administrative: the county holds the building code enforcement role that towns hold elsewhere, so plan review, permit issuance and inspection all sit at the courthouse rather than a town hall.
Who handles permitting in Eau Claire County?
The Land Use Controls Division administers and enforces building and construction regulations, shoreland protection and zoning for unincorporated Eau Claire County, with a Land Use Manager serving as Zoning Administrator and a county building inspector conducting inspections. Conditional use permits are granted by the Planning and Development Committee after a public hearing with town board input.

Permit types
Residential permits
For one- and two-family dwellings and additions including decks, submit legible scaled drawings with enough detail for construction, including exterior views showing doors, windows, roof, chimneys, grade, footings, foundation walls and materials. The county reviews, issues and inspects, with driveway access permits obtained from the town first where applicable.
How Wisconsin contractor licensing works
Wisconsin has no state general contractor license for commercial work — the city's own forms note that 2013 Wisconsin Act 20 ended state building-contractor registration on July 2, 2013. For one- and two-family work the state requires a Dwelling Contractor certification on the business and a Dwelling Contractor Qualifier on an individual, and under Wis. Stat. 101.65(1m) Eau Claire County may not issue a building permit to a contractor who cannot produce them; owner-occupants are exempt. Electricians and plumbers are licensed statewide by DSPS. HVAC contractors only register with the state — there is no state HVAC license — which is exactly where local rules step in. Eau Claire County licenses no trades; state credentials govern, and the county building inspector verifies them at permit issuance.
Commercial permits
Commercial building code plan review routes to the state or a delegated municipality — the county holds no commercial plan review delegation, and the City of Eau Claire's own delegation is capped below fifty thousand cubic feet. County conditional use permits for commercial land uses are granted by the Planning and Development Committee after a public hearing, with applications due by noon three weeks before the hearing.
Mechanical work, and where the state reviews directly
Commercial plan review in Wisconsin is a two-step: under Wis. Stat. 101.12(3)(h) the plan approval comes first and the local permit cannot issue without it. The state review trigger is 25,000 cubic feet, plus categorical triggers at any size for schools, high-hazard occupancies and residential buildings of three or more units. At 50,000 cubic feet plans must be prepared, signed and sealed by a Wisconsin-registered design professional, with a supervising professional retained for construction observation. Commercial plumbing plans go to review at sixteen or more fixtures. Property owners within six hundred sixty feet of a proposed conditional use are notified, and a public notice is published before the hearing.
Eau Claire County permit costs and fees
County permit fees are published with the application forms. The planning figure that matters is the review window and, for conditional uses, the three-week filing deadline before a hearing.
| Item | Fee or rule |
|---|---|
| Building and electrical permit | Per the county fee schedule, applied for through Land Use Controls |
| Application review | Up to ten business days once all forms, plans and documents are complete |
| Conditional use permit | Application due by noon three weeks before the Planning and Development Committee hearing |
| Land use, shoreland and erosion control permits | Per the county schedule |
Verify authority before anything else. The county's own first step is to check who issues the permit — most properties are in a city, village or town rather than under county authority — and it publishes a permitting authority lookup tool for the purpose.
Trade permits and who may pull them
Trades are state-credentialed. Because the county holds the building code role, electrical permits for dwellings and detached buildings come from the county as well.
Permit required
- Electrical — state credentials; county permit for new or re-wired services and wiring in detached buildings
- Plumbing and HVAC — state credentials; county permits for system alterations
- Private onsite wastewater systems — county sanitary permitting
- One- and two-family general work — state Dwelling Contractor plus Qualifier
Typically exempt
- Major equipment replacements and normal repairs of HVAC, plumbing and electrical equipment
- Non-structural repairs deemed minor by the building inspector
How to apply for a Eau Claire County building permit
The county's lookup tool settles it; most parcels are municipal, not county.
Some towns require it before the building permit can issue.
Including exterior elevations with footings, foundation walls and materials.
Third floor, Suite 3344, weekdays 8:00 a.m. to 4:30 p.m.
The clock runs once the file is complete.
Rather than a town inspector, as elsewhere in the state.
Review, corrections and what actually causes delay
The county's stated review window is up to ten business days once everything is in, so completeness is the whole game. Conditional uses run on the committee calendar instead, with applications due three weeks ahead of the hearing.
Inspections in Eau Claire County
