Frequently Asked Questions
Can I build an ADU near the UW-Madison campus?
Yes — and Madison makes it particularly easy in urban transect zones (TR-U1, TR-U2) near campus. In these zones, ADU approval is by-right (no discretionary review), no additional parking is required, and setbacks are minimal. Detached ADUs up to 1,000 sqft are permitted. Madison's ADU program is among the most progressive in the Midwest, designed in part to address the intense student rental housing demand around the University of Wisconsin campus.
What is Madison's transect zoning system?
Madison replaced traditional Euclidean zoning with a form-based transect code in 2013 under Chapter 28. The transect ranges from TR-C1 (countryside, lowest density) to TR-U2 (urban core, highest density). Each zone reflects an urban-to-rural intensity gradient — the higher the zone designation, the more urban the character and the more flexibility for mixed uses, reduced parking, and denser development. You can find your property's transect zone on the Madison zoning map at cityofmadison.com/dpced/planning/zoning.
Does Madison require parking for ADUs?
No — in Madison's urban transect zones (TR-U1 and TR-U2), no additional parking is required for an ADU. This is one of the most progressive ADU parking policies in the Midwest. In suburban transect zones (TR-C3, TR-C4), one parking space may be required. Madison has actively reduced parking requirements city-wide to encourage density and transit use.
What are the Dane County Farmers Market and cottage food rules in Madison?
The Dane County Farmers Market on Capitol Square is one of the nation's largest producers-only markets — vendors must grow or produce what they sell. Wisconsin Cottage Food Law (WI Stat. 97.29) allows home-based food production up to $20,000 annual revenue without a permit. In-person sales only — Wisconsin does not allow online cottage food sales.

My property is near Lake Mendota — are there extra restrictions?
Yes. Properties within 300 feet of Lake Mendota and other navigable waterways in Madison are subject to the Wisconsin DNR Shoreland Overlay regulations. These rules impose: minimum 75 ft shoreline setback for structures, impervious surface limits (typically 15-30% of the shoreland area), and vegetation preservation requirements within 35 ft of the ordinary high-water mark. These restrictions apply in addition to city zoning rules. Contact Madison Planning at (608) 266-4635 for a shoreland consultation before starting any project near the lakes.
