La Crosse County administers zoning, sign, public works and telecommunications ordinances in every unincorporated town except Campbell and Burns, and administers floodplain and shoreland ordinances across all unincorporated areas — a wider reach than most Wisconsin counties of its size.
The department issues zoning occupancy permits and several other land use permits, maintains the county's farmland preservation programme under its zoning code, and operates a public parcel viewer for general property line reference.
This guide covers unincorporated La Crosse County. The county has no zoning authority within the cities of La Crosse or Onalaska or the villages of Bangor, Holmen and Rockland, and the towns of Campbell and Burns administer their own zoning.
The zoning permit comes last, not first. The county states that your zoning permit cannot be issued until all other applicable permits are in place — the reverse of the sequence in most Wisconsin counties. Applications are processed in the order received, typically taking one to two weeks.
What requires a building permit in La Crosse 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), La Crosse County may not enforce different technical standards — local ordinances must strictly conform to the state codes.
Typically permit required
- Zoning occupancy permits for development in the towns under county zoning
- Floodplain and shoreland approvals across all unincorporated areas of the county
- Sanitary permits, with county applications used for reconnections, repairs and non-plumbing sanitation systems, and the state application for all other system types
- Land division and subdivision approvals under the county's platting chapter
- Sign, public works and telecommunications approvals under the county ordinances
- The town building permit
Often exempt
- Projects that do not involve a structural alteration to the three-dimensional footprint of the building
- Anything inside La Crosse, Onalaska, Bangor, Holmen or Rockland, and the towns of Campbell and Burns for general zoning
- 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
Building standards are statewide. La Crosse County's layer is comprehensive land use over most of the rural county, plus floodplain and shoreland everywhere unincorporated. The county does not require a contractor's license for many types of work, though state or town codes may.
Who handles permitting in La Crosse County?
The Zoning, Planning and Land Information Department issues zoning occupancy permits and administers the county's land use ordinances. Town building inspectors issue building permits. Landowners in unincorporated areas may request notice of proposed ordinance changes affecting their property under state statute.

Permit types
Residential permits
A rural house needs the county zoning occupancy permit — submitted with a site map, construction plans, other attachments and the fee — and the town's building permit under the Uniform Dwelling Code with state Dwelling Contractor credentials. New residential or manufactured home construction carries a published county permit fee of two hundred fifty dollars; residential additions, alterations, accessory buildings and signs are one hundred twenty-five dollars.
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) La Crosse 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. La Crosse County does not require a contractor's license for many types of work, though state or town codes may impose their own requirements.
Commercial permits
Commercial development under county zoning needs the county's approvals before the town's building permit. Building code plan review routes to the state or a delegated municipality; the county holds no commercial plan review delegation, and the City of La Crosse itself holds only small-commercial delegation.
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. Applications for work within the floodplain or shoreland may also require review or certifications from an engineer.
La Crosse County permit costs and fees
County permit fees are published by category, and the sequencing rule means the county fee is typically the last one paid rather than the first.
| Item | Fee or rule |
|---|---|
| New residential or manufactured home construction | Two hundred fifty dollars |
| Residential additions, alterations, accessory buildings and signs | One hundred twenty-five dollars |
| Manufactured home community additions, alterations and access | One hundred dollars |
| Building permit | Set by the town |
Unrecorded land divisions block permits. Under the county's subdivision and platting chapter, no sanitary permit or zoning occupancy permit may be issued authorising building on a subdivision or replat within its jurisdiction that is not of record, until the chapter's requirements are fully met.
Trade permits and who may pull them
Trades are state-credentialed and permitted at town level; the county handles zoning, sanitary and land division.
Permit required
- Electrical, plumbing and HVAC — state credentials; town permits
- Sanitary systems — county application for reconnections, repairs and non-plumbing systems; state application for other system types
- Floodplain or shoreland work — county approval, possibly with engineer certification
- One- and two-family general work — state Dwelling Contractor plus Qualifier
Typically exempt
- Projects with no structural alteration to the building's three-dimensional footprint
- Work inside the cities and villages, or in Campbell and Burns for general zoning
How to apply for a La Crosse County building permit
County zoning covers all unincorporated towns except Campbell and Burns; the cities and villages are outside it entirely.
These apply across all unincorporated areas regardless of general zoning.
The county will not issue the zoning permit until the others are in place.
With site map, construction plans, attachments and fee; one to two weeks in the order received.
County forms for reconnections, repairs and non-plumbing systems; state forms otherwise.
The town issues and inspects under the state code.
Review, corrections and what actually causes delay
The sequencing rule is the whole planning problem here. Because the county zoning permit waits on everything else, a single outstanding approval — sanitary, access, engineering certification — holds the entire file, and the one-to-two-week clock does not start until the rest is done.
Inspections in La Crosse County
Building inspections are the town's. County involvement covers zoning compliance, floodplain and shoreland, and sanitary systems.
