Oneida County, Wisconsin Building Permit Guide

In Oneida County, the Planning and Zoning Department at the courthouse, 1 South Oneida Avenue in Rhinelander, with a branch office in Minocqua (715-369-6130), issues zoning, shoreland, sign and private septic permits for the unincorporated land of all 20 towns. The county holds no Uniform Dwelling Code delegation, so the building permit for a new home comes from the inspector each town contracts with, or from the City of Rhinelander inside the city. Under Resolution 6-2026, effective January 1, 2026, a zoning permit costs $0.22 per square foot off the water and $0.25 on waterfront lots, with a $100 minimum.

What requires a permit in Oneida County?

County zoning applies in the unincorporated areas of all 20 towns, with one exception: in the Towns of Enterprise, Monico and Sugar Camp it covers only land within 1,000 feet of a lake or 300 feet of a river or stream. The department says zoning permits are needed for most structures, from seasonal and year-round homes to garages, storage buildings and decks.

The county’s handout reminds owners that town, state and federal permits may also be needed: most towns require a driveway permit, driveways must be at least 5 feet from lot lines, and wetland fill, dredging and riprap can need DNR or U.S. Army Corps of Engineers approval. Private covenants that are stricter than county rules must be disclosed before a county permit is finished.

What the county decides and what the state holds

The county writes its own Zoning and Shoreland Protection Ordinance (Chapter 9), septic ordinance (Chapter 13), subdivision ordinance (Chapter 15), floodplain ordinance (Chapter 20) and nonmetallic mining rules (Chapter 22), and sets the fees for them. How houses are built is set by the state Uniform Dwelling Code, which, as the county’s handout puts it, every municipality has had to enforce since December 18, 2003; each town decides how it handles that enforcement.

Oneida County building department: who handles permitting

The Planning and Zoning Department, led by Director Karl Jennrich and overseen by the county board’s Planning and Development Committee, issues zoning permits in every town and handles the septic, subdivision and floodplain programs. Rural fire numbers come from the county’s Land Information Office (715-369-6179).

Who issues building permits in each community

The DSPS list of Uniform Dwelling Code delegated agents (current as of 9/24/2026) has no row for Oneida County, and lists the City of Rhinelander and all 20 towns as delegated in their own right. The county’s list of zoning and building code officials names the inspector each town uses.

Driveway permits on town roads come from each town; the county list gives the town clerk, chair or shop for each.

Oneida County permit types

All county applications and forms are posted on the department’s public documents page, and every fee is paid with the application. The page also posts a zoning map sheet for each town, showing the district for each section and lot, and the department’s page links to its Ascent Permit Management system.

Residential permits

• Zoning permit: priced by floor area for homes, additions, garages, decks, patios, walkways, retaining walls and lofts, counting each full story and basement; anything that cannot be measured that way, such as a fireplace, a fence or a roof pitch change, is a flat $100.
• Waterfront projects: charged the higher waterfront rate, including lots on flowages such as Lake Nokomis and the Rainbow Flowage; boathouses have their own fees, and shoreyard alterations, mitigation plans and impervious surface reviews add separate approvals.
• Sanitary permit: the county form or the state form, filed under the county’s submittal requirements by a certified soil tester and licensed plumber; existing systems may need an evaluation before a house is added to.
• Building permit: issued by the town’s UDC inspector after the zoning permit.

Commercial permits

Commercial buildings, including duplexes and apartment buildings, pay the commercial zoning rate, and a new, expanded or changed business use needs county approval, often as a conditional use ($750) or an administrative review permit ($500). Only commercial projects can buy an early start ($200). Construction plans for commercial buildings go through the state Commercial Building Code process, with DSPS plan approval for buildings of the sizes the state reviews.

For tenant improvements and new commercial builds, Alliance handles commercial permit applications through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Zoning district and setbacks: check the town’s zoning sheet; a structure that cannot meet setbacks always needs a permit and may need a variance from the Board of Adjustment.
• Septic: the sanitary permit for a new or replaced system.
• Land division: a subdivision or certified survey review for new lots.
• Floodplain: Chapter 20 applies in mapped flood areas.
• Driveway and address: the town or county highway driveway permit and a fire number.
• State and federal water permits for wetland fill, dredging, riprap and other shoreland work.

Oneida County permit costs and fees

Fees are set by Resolution 6-2026, effective January 1, 2026. Cents are rounded to the nearest dollar, after-the-fact applications cost triple, and county permits expire two years after issue and cannot be renewed. Septic fees can change if DSPS or the DNR raise state fees. Town building permit fees are set by each town and its inspector.

Worked example from the schedule: a 24 by 24 foot detached garage on an off-water lot is 576 square feet, so the zoning permit is 576 × $0.22, or $126.72, rounded to $127. The same garage on a waterfront lot is 576 × $0.25, or $144. A 10 by 12 foot shed (120 square feet) works out to $26.40 at the off-water rate and so pays the $100 minimum, if it needs a permit at all.

Trade permits and who may pull them

The county issues no electrical, plumbing or HVAC permits for buildings; those systems in a new home are inspected under the town’s Uniform Dwelling Code permit by its inspector. The county’s role in the trades is the private septic system.

• Septic design and installation: the county posts a list of certified soil testers and plumbers. Every sanitary permit submittal includes the original application and two copies with a plot plan; repairs and reconnections add the county’s existing system evaluation form, and pre-1980 systems need the original soil boring.
• Changes: changing plans or plumbers on an open sanitary permit costs $100; a permit may be transferred between owners for $50 and renewed once for $50.
• Maintenance: systems are tracked through the county’s maintenance program, billed at $5 a year on the tax roll, and the county posts a septic pumpers list.
• Dwelling contractors: the town inspector checks the state Dwelling Contractor certification and Qualifier for new homes; owner-occupants building their own homes are exempt.

How to apply for permits in Oneida County

Review, corrections and what causes delay

Conditional uses, ordinance amendments ($600 petition) and Board of Adjustment appeals go to public hearing; rescheduling an appeal costs $500, and contested appeals carry a $600 minimum plus costs. Waterfront projects can add mitigation and impervious surface reviews. The Minocqua branch is closed to the public Tuesday through Thursday, so northern applicants who need the counter should plan around Mondays and Fridays. Residents can sign up to receive notice of any proposed ordinance change that affects their land.

Inspections in Oneida County

County staff inspect septic installations and check zoning compliance; a staff site inspection requested by the public costs $300, with no credit toward a permit, and each return visit another $300. Additions and remodels on septic pay a $150 sewage system inspection fee. Construction inspections for a new home are made by the town’s UDC inspector, or by the City of Rhinelander inside the city, at the stages that inspector sets out with the permit.

Several of the inspectors on the county list take only new homes and cottages, so owners planning a large remodel in those towns should ask the town clerk who handles it.
