Wood County adopted its zoning ordinance in 1934, and it remains in effect in all twenty-two towns within its jurisdiction. Because its scope is narrow, twelve of those towns have adopted their own zoning ordinances — and where they have, zoning administration and enforcement is the town's responsibility, not the county's.
The Planning and Zoning Office handles planning, land records management, code enforcement and economic development with a staff of seven, and is the county agency responsible for regulating and inspecting septic systems, issuing sanitary permits and enforcing the county's private sewage system ordinance.
This guide covers unincorporated Wood County. Wisconsin Rapids, Marshfield, Nekoosa and Pittsville permit their own construction; Marshfield and Wisconsin Rapids both hold special commercial plan review delegation.
Two zoning regimes, twenty-two towns. The county's 1934 ordinance still applies across all towns in its jurisdiction, but twelve of the twenty-two have adopted their own town zoning ordinances — and in those towns, zoning administration and enforcement belong to the town. The county directs all town zoning and land use questions to the respective town.
What requires a building permit in Wood 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), Wood County may not enforce different technical standards — local ordinances must strictly conform to the state codes.
Typically permit required
- County sanitary permits for installing, repairing or altering a septic system, holding tank or other domestic wastewater system
- Shoreland and floodplain approval before starting filling, grading, ponding, lagooning, dredging, excavating or any soil disturbance work
- Shoreland and floodplain approval for additions or alterations to existing structures, or reconstruction outside the current building footprint
- County zoning approval under the 1934 ordinance, in towns without their own
- Town zoning approval, in the twelve towns that adopted their own ordinances
- The municipal building permit
Often exempt
- County zoning administration in the twelve towns with their own ordinances — direct those questions to the town
- Anything inside a city or village, which permits independently
- 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. Wood County's own regulatory weight sits in the sanitary programme and the shoreland and floodplain review, since the 1934 general ordinance is narrow by modern standards — which is precisely why so many towns wrote their own.
Who handles permitting in Wood County?
The Planning and Zoning Office administers county zoning, shoreland and floodplain, and the sanitary programme, issuing sanitary permits and enforcing the private sewage system ordinance. State-licensed plumbing inspectors carry out sewage system inspections. Municipalities issue building permits.

Permit types
Residential permits
A rural house needs the county sanitary permit before the municipality can issue the building permit, plus shoreland or floodplain approval where applicable and zoning approval from whichever authority holds it for that town. Only licensed plumbers may install septic systems, and inspection requests must come from the plumber responsible for the installation, with at least twenty-four hours' notice.
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) Wood 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. Wood County licenses no trades, but only state-licensed plumbers may install septic systems, and state-licensed plumbing inspectors carry out the sewage system inspections.
Commercial permits
Commercial development follows the applicable zoning regime — county or town — plus the county's sanitary, shoreland and floodplain programmes. Building code plan review routes to the state or a delegated municipality; the county holds no commercial plan review 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. The county recommends obtaining and comparing detailed bids for septic work, and maintains a consumer complaint process alongside its inspection programme.
Wood County permit costs and fees
County fees cover the sanitary programme, with transfer and recording charges published alongside; municipal fees cover the building permit.
| Item | Fee or rule |
|---|---|
| Sanitary permit | Per the county schedule, through Planning and Zoning |
| Sanitary permit transfer | A published transfer fee applies |
| Recording fee | Charged for the one-sided recorded document |
| Building permit | Set by the municipality |
The sanitary permit unlocks the building permit. The county's own citizen guidance describes the sequence plainly: the sanitary permit issues first, and then the municipality can issue a building permit — the legal permission to begin construction, confirming approved plans for the new structure, addition or renovation.
Trade permits and who may pull them
Trades are state-credentialed and permitted municipally; septic installation is restricted to licensed plumbers under county administration.
Permit required
- Electrical, plumbing and HVAC — state credentials; municipal permits
- Septic system installation — licensed plumbers only, under a county sanitary permit
- Soil disturbance in shoreland or floodplain — county approval before starting
- One- and two-family general work — state Dwelling Contractor plus Qualifier
Typically exempt
- Zoning matters in the twelve towns with their own ordinances — handled by the town
- Work inside cities and villages
How to apply for a Wood County building permit
The 1934 county ordinance, a town ordinance, or both, depending on the town.
The municipality's building permit follows it.
Filling, grading, ponding, dredging and excavating all require it.
Only licensed plumbers may install systems.
Requests must come from the installing plumber, with at least twenty-four hours' notice.
Which approves the plans and permits construction.
Review, corrections and what actually causes delay
Wood County's split zoning history is the trap: assuming the county administers zoning in a town that adopted its own, or the reverse. Establish the regime first, then run the sanitary permit, which gates the building permit.
Inspections in Wood County
Sewage system inspections are performed by state-licensed plumbing inspectors to confirm the work matches the state plumbing code and the conditions of the sanitary permit. Building inspections are municipal.

Frequently asked questions
Does Wood County issue building permits?
No. The municipality issues the building permit; the county issues sanitary permits and administers zoning, shoreland and floodplain.
How old is the county zoning ordinance?
Wood County adopted its zoning ordinance in 1934, and it remains in effect in all twenty-two towns within its jurisdiction.
Why do towns have their own ordinances?
Because the county ordinance is narrow in scope, twelve of the twenty-two towns adopted their own — and there, zoning administration and enforcement is the town's responsibility.
What needs shoreland or floodplain approval?
Filling, grading, ponding, lagooning, dredging, excavating and any soil disturbance work, plus additions, alterations or reconstruction outside the existing building footprint.
Who can install a septic system?
Only licensed plumbers. Inspection requests must come from the plumber responsible for the installation, ideally at least twenty-four hours in advance.
What comes first, sanitary or building permit?
The sanitary permit. Once it is issued, the municipality can issue the building permit.
