Sawyer County, Wisconsin Building Permit Guide

In Sawyer County, the Zoning & Conservation Department at the courthouse, 10610 Main Street, Suite 49, Hayward (715-634-8288), issues land use permits under the county zoning ordinance, sanitary (septic) permits, grading permits and fire numbers. It does not issue building permits: the county says the City of Hayward and the towns and villages enforce the Uniform Dwelling Code through their own inspectors. Under the fee schedule effective January 1, 2026, a house’s land use permit starts at $300 and a septic permit is $450.

What requires a permit in Sawyer County?

Section 9.2 of the Sawyer County Zoning Ordinance requires a land use permit (LUP) for any new or replacement structure built, assembled or placed on land, whether it is meant to stay or is temporary. A structure escapes the requirement only if all four of these are true: it is an accessory structure not used for human habitation, the lot already has a dwelling, it is not within 300 feet of shoreland, and it is no larger than 100 square feet.

The county’s accessory building rules add a vacant-lot exception: one storage shed of up to 144 square feet and under 14 feet tall on a parcel of at least 20,000 square feet outside a platted subdivision, with a fire number, still under a land use permit. Otherwise the county will not issue a permit for an accessory building unless a dwelling or principal use exists or is built at the same time. A dwelling must be at least 20 feet by 20 feet with 500 square feet of habitable living area.

What the county decides and what the state holds

The county writes its zoning ordinance (Appendix D), floodplain (Appendix A), shoreland-wetland protection (Appendix B, effective April 19, 2017 and amended January 17, 2019) and subdivision rules, and the private sewage ordinance (#1-2011). These apply in the unincorporated towns with one exception: the county tells Town of Spider Lake owners to get land use permits and zoning information from the town’s own Zoning Administrator (zoning@townofspiderlakewi.gov), while the county still issues their sanitary permits and 911 numbers. The City of Hayward and the villages are separate municipalities. The building code is the state’s. The county is not a UDC delegated agent on DSPS’s list (current as of September 24, 2026), and no Sawyer County municipality appears on DSPS’s commercial plan review or commercial electrical delegation lists, so commercial plans and commercial electrical permits go to DSPS. Septic systems that need state plan approval are also reviewed by DSPS.

Sawyer County building department: who handles permitting

Zoning & Conservation issues the county permits and schedules public hearings for the Zoning Committee and the Board of Appeals. The county sanitarian reviews septic designs and inspects installations. Building permits are a separate layer: the county’s permit sheet says plainly that land use permits and building permits are not the same thing, and that towns may require their own building permits and fees.

Towns, villages and Hayward: who permits a new home

The county states that the City of Hayward and all towns and villages enforce the UDC. DSPS’s delegation list (September 24, 2026) shows delegations for Hayward, the Village of Radisson and 14 of the 16 towns; it does not list the villages of Couderay, Exeland and Winter or the towns of Meteor and Weirgor, where DSPS’s Inspector Lookup Tool shows the state-appointed UDC inspector unless the municipality says otherwise. Populations are Census estimates.

Sawyer County permit types and application documents

A land use permit application must include a plot plan showing where the structure goes (it can be drawn on Beacon satellite imagery), the measured setbacks, an estimated cost, the fee, and for a dwelling or a building with mixed uses a semi-detailed interior layout. The owner or an authorized agent signs it, though a contractor may fill it out. On shoreland, the impervious surface share of the lot must be calculated; above 15%, a shoreland mitigation agreement must be notarized and recorded.

Residential permits

• Sanitary permit. A certified soil tester evaluates the site, and only a Wisconsin licensed plumber may design the system and apply. The permit must be in the office before the county will process a land use permit, and it is valid for 2 years. Privy permits can be issued to the owner.
• Connection or reconnection permit ($100). Needed when a foundation is changed or moved, or new plumbing such as a garage toilet connects to an existing system; a post-1994 soil test must be on file.
• Land use permit. Priced by habitable area for homes and by size for accessory buildings; within 12 months of issue every structure on it must be fully enclosed, with one 6-month extension if requested in time.
• Fire number. Required for any land with human occupancy, including camping or a shed on vacant land; bunkhouses and temporary guest quarters get a yellow sign.

Commercial permits

New commercial and industrial structures need a county land use permit ($250 plus $5 per $1,000 of construction cost), and a new business moving into an existing building needs one priced by employees and floor area. State plan approval, commercial electrical permits and commercial septic plans that need state approval come from DSPS.

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

What comes before the building permit

• Zoning district and setbacks. Check the district’s permitted and conditional uses. Setbacks: 75 feet from the ordinary high-water mark; road setbacks of 130 feet from the centerline of state highways, 75 from county highways and 63 from town roads; dwellings 10 feet from one side line with 40 feet in total, 30 from the front and 40 from the rear.
• Floodplain. Floodways allow few structures; flood fringe building must meet lowest-floor elevation, floodproofing and dry-land access standards.
• Driveway. From the road’s owner: the town, the County Highway Department or WisDOT.
• Conditional use, rezoning or variance. Public hearings before the Zoning Committee or Board of Appeals.

Sawyer County zoning and sanitary permit costs

These figures come from the Sawyer County Zoning Administration Fee Schedule effective January 1, 2026. Payment is by cash or check only, and the schedule says all fees can be up to triple for work done before a permit is issued. Town building permit fees are separate.

Worked example from the schedule: a new 1,800-square-foot home (habitable area) on a lot that needs a septic system and a fire number pays $400 for the land use permit, $450 for the sanitary permit, $50 for the soil test review and $125 for the fire number sign, $1,025 to the county before the town’s UDC permit. A detached garage of 600 square feet adds $150. Certified survey map review is $100 per map plus $50 per lot, and a property inspection is $75.

Trade permits and who may pull them

The county issues no electrical, plumbing or HVAC permits; for a house that work is inspected under the municipality’s UDC permit. Septic work is the county’s trade rule: homeowners may not install, inspect or repair their own system unless they are licensed plumbers, because only Wisconsin licensed plumbers may work on private onsite wastewater systems. The county posts lists of certified soil testers, licensed plumbers, septic pumpers, surveyors and wetland delineators known to work in the area.

For new homes and additions, the state requires the builder to hold a Dwelling Contractor certification with a Dwelling Contractor Qualifier unless the owner who will live there does the work, and the town’s inspector cannot issue the UDC permit without it. DSPS licenses electricians and plumbers and registers HVAC contractors; commercial electrical permits come from DSPS because no Sawyer County municipality is delegated for them.

How to apply for a Sawyer County permit

Review, corrections and what causes delay

The county will not begin reviewing a land use permit until the sanitary permit is in the office. Shoreland lots that exceed 15% impervious surface need a recorded mitigation agreement, and hearing items can be delayed by republication, which carries a $150 refiling fee. Structures must be enclosed within 12 months of the permit.

Inspections and final approval in Sawyer County

For septic systems, the plumber schedules the installation inspection with the county sanitarian after the permit is issued, and the plumber receives a state or county placard for the job. County zoning staff may inspect properties for land use compliance; a requested property inspection is $75. Construction inspections of a new home are done by the town’s or municipality’s UDC inspector, following the UDC stages: footings and foundation, rough framing and trades, insulation, and a final before occupancy. Under the land use permit, the structure must be completely enclosed within 12 months of issue.

Does Sawyer County issue building permits?

No. The county issues land use, sanitary, grading and fire number permits; the UDC building permit for a home comes from the town, village or the City of Hayward.

Do I need a permit for a small shed?

Not from the county if it is 100 square feet or less, not lived in, on a lot that already has a house and more than 300 feet from shoreland. Otherwise a land use permit is required, even for a structure on skids.

How much is a septic permit?

$450 ($100 state and $350 county), plus $50 to review the soil test. A licensed plumber must design the system and apply.

Can I install my own septic system?

No, unless you are a Wisconsin licensed plumber. A privy permit, however, can be issued to the property owner.

How long do I have to finish?

Structures on a land use permit must be completely enclosed within 12 months, with one 6-month extension if you ask before the deadline. Sanitary permits last 2 years.

What happens if I build before getting a permit?

County fees can be up to three times the normal amount for work done before the permit is issued.
