Dane County Permits: What the County Handles vs. Your City or Town

Direct Answer: In Dane County, who issues your permit depends entirely on which side of a municipal boundary your parcel sits on. Cities and villages — Madison, Fitchburg, Middleton, Verona, and the rest — run their own zoning and building permitting; the county has no role there. In unincorporated towns, Dane County Planning & Development is the zoning authority (with six named exceptions that zone themselves), while the town issues the building permit, and separately, Public Health Madison & Dane County issues septic permits and the Land & Water Resources Department issues erosion-control permits. A single rural building project can touch three or four different offices before it's done.

Key Takeaways

• Inside a city or village (Madison, Fitchburg, Middleton, Verona, Monona, Stoughton, and others), that municipality handles all zoning and building permitting — the county has no jurisdiction there (source).
• Dane County Planning & Development is the zoning authority for unincorporated towns — except six that opted out and zone themselves: Berry, Blue Mounds, Bristol, Springfield, Sun Prairie (town), and Westport (source).
• In most unincorporated towns, you need an approved county zoning permit before the town will issue a building permit — sequential, not interchangeable (source).
• Septic (POWTS) permits come from a third office entirely — Public Health Madison & Dane County, not Planning & Development (source).
• Zoning variances in unincorporated Dane County go to the county Board of Adjustment under Wis. Stat. §59.694, not a town or city board (source).
• Not sure if your parcel is incorporated? Check Access Dane or run a GovCodex permit check before assuming which office to call.

Who Handles What in Dane County?

Why Does a County Government Issue Building-Related Permits at All?

Wisconsin counties get zoning authority over unincorporated land from state statute, not municipal charters. Dane County adopted a general zoning ordinance (Chapter 10 of the Dane County Code) that individual town boards then formally adopted, town by town — not automatically countywide. Cities and villages are self-governing under their own municipal codes and never fall under the county's zoning ordinance (Dane County Planning & Development FAQ). Incorporated = the municipality runs permitting. Unincorporated town = the county runs zoning (mostly), and the town runs building permits.

Which Towns Are Under Dane County Zoning — and Which Aren't?

Most of Dane County's towns operate under the county's zoning ordinance. But a 2015 state law (2015 AB 563) gave Dane County towns the one-time-per-cycle option to withdraw from county zoning and adopt their own — first available in 2017, and revisitable every three years after that (Axley Law summary; Cap Times coverage).

As of the county's current published FAQ, six towns have exercised that option and now administer their own zoning instead of the county's: Berry, Blue Mounds, Bristol, Springfield, Sun Prairie (the town, not the city), and Westport (source). If your property is in one of those six, your first call for a zoning permit is the town office. In any other unincorporated town, the county is your zoning authority. Because towns can revisit this decision periodically, confirm current status with your town clerk rather than assuming based on an older source.

What Does Dane County Planning & Development Actually Administer?

For towns under county zoning, Dane County Planning & Development issues zoning permits for new structures, additions, decks, pools, structural repairs to nonconforming buildings, and even keeping domestic fowl or bees (source). It also administers shoreland and floodplain zoning under Chapter 11 of the county code, implementing the state's minimum standards in Wis. Admin. Code NR 115 (shoreland) and NR 116 (floodplain) — land within 300 feet of a river or stream, or 1,000 feet of a lake or pond, generally needs its own review (Dane County Code Ch. 11; Wisconsin DNR).

Land division is a Planning & Development function too: certified survey maps (fewer than five lots) go through the County Land Division Review Officer, and larger subdivision plats go to the Zoning and Land Regulation Committee — both also require town sign-off, plus sign-off from a nearby city or village if the parcel falls in its extraterritorial jurisdiction (source).

What Planning & Development does not handle: septic permits and erosion control, even in unincorporated towns. Private on-site wastewater treatment (POWTS) sanitary permits are issued by Public Health Madison & Dane County (source); erosion-control/stormwater permits for larger land-disturbing projects come from the county's Land and Water Resources Department (source). Budget time to coordinate with whichever office applies — they don't share one intake form.

Who Handles the Actual Building Permit and UDC Inspection in a Town?

This is the wrinkle that trips people up. Wisconsin's Uniform Dwelling Code (UDC, Wis. Admin. Code SPS 320–325) governs one- and two-family dwelling construction statewide, but enforcement is delegated locally — a municipality can use its own certified building inspector, contract with another municipality or the county, or (for new one- and two-family dwellings only) rely on state inspection. In unincorporated Dane County, towns generally handle their own building permit and UDC inspection separately from the county's zoning permit. The Town of Dane directs residents to its own Building Inspector for the building permit, after the Dane County zoning permit is approved (Town of Dane). The Town of Dunn works the same way: a Dane County zoning permit is required first, then the town's own Wisconsin-certified UDC inspector handles plan review and inspections (Town of Dunn).

That order — county zoning permit first, then town building permit and UDC inspection — is the general pattern, but the exact arrangement (in-house inspector vs. contracted vs. shared with a neighboring town) varies by town. Confirm with your specific town clerk or building department before scheduling work. For the mechanics of UDC review itself, see our guide to Wisconsin's Uniform Dwelling Code.

What About Variances in Unincorporated Areas?

If your project in an unincorporated town needs relief from a setback, height, or other dimensional requirement, the request goes to the Dane County Board of Adjustment — a five-member body appointed by the County Executive that hears variance petitions and administrative appeals under Wis. Stat. §59.694. Variances are "generally limited to setbacks or other dimensional requirements," and an applicant has to show a unique or unusual condition beyond their control, not just that compliance is inconvenient or costly. Administrative appeals of a zoning administrator's decision follow a similar public-hearing process and must be filed within 30 days (source; Wis. Stat. §59.694). Compare that to our Madison zoning variances guide, which covers the City of Madison's own board — a separate, city-only process that never touches the county board.

A Concrete Example: Town of Dunn vs. City of Madison

Say two homeowners each want to add a detached garage. One lives in the Town of Dunn (unincorporated, under Dane County zoning); the other lives in the City of Madison.

The Town of Dunn homeowner needs a Dane County zoning permit first, confirming the garage meets setback and lot-coverage rules under the county's zoning ordinance. Only after that's approved can they apply for a Town of Dunn building permit, reviewed by the town's own certified UDC inspector (Town of Dunn). Two offices, two applications, in sequence.

The Madison homeowner applies once, to the City of Madison, whose Building Inspection Division handles zoning compliance and the building permit together in-house — no county involvement. See our Madison building permit guide for that process. Same project type, same county, two entirely different paths.

How Do I Know If My Parcel Is Incorporated or Unincorporated?

If you're not sure whether your address is inside a city/village or an unincorporated town, look it up on Access Dane, the county's property and land-records search, by owner name, address, or parcel number, or check with your local assessor. Don't assume based on mailing address or ZIP code — a "Madison, WI" mailing address can still sit in an unincorporated town outside city limits, and vice versa.

Frequently Asked Questions

Do I need anything from Dane County if I live in Madison, Fitchburg, or another city?

No. Cities and villages handle all their own zoning and building permitting; the county's jurisdiction is limited to unincorporated towns (source).

My town is one of the six that opted out of county zoning — who do I call?

Your town's own zoning office for general zoning permits, not Dane County Planning & Development. Towns can revisit the opt-out decision periodically, so confirm current status with your town clerk before applying (source).

Can I get a town building permit without a county zoning permit first?

In towns under county zoning, generally no — published guidance from Dane County and individual towns (e.g., the Town of Dane and Town of Dunn) treats an approved county zoning permit as a prerequisite for the town building permit (source). Confirm the exact sequence with your specific town, since local practice can vary.

Who do I contact about a septic permit for a rural property?

Public Health Madison & Dane County, not Dane County Planning & Development — POWTS sanitary permits are a separate program run by a different agency (source).

Verify the Rules for Your Property

Permitting authority in Dane County depends on your exact parcel, and it can shift when a town's zoning status changes. Treat this article as a map, not a final answer. Check GovCodex's Dane County permit catalog for jurisdiction-specific requirements, or run a permit check against your address to see which office — county, town, or city — actually governs your project before you apply anywhere.
