Full Breakdown

Dane County Chapter 10 addresses home occupations as an accessory use to residential dwellings. In residential-transitional (TR) districts, home occupations must be clearly secondary to the residential use, with limited external evidence of business activity. Agricultural districts are generally more permissive about on-farm businesses. A conditional use permit or home occupation approval may be required for businesses that could affect the residential character of the area.

Violations & Fines

Home occupations that violate zoning conditions are subject to Dane County zoning enforcement. Complaints are investigated by Dane County Planning.

Does a Dane County home occupation need a conditional use permit?
Sometimes. If the business could affect the residential character of the neighborhood, parking, traffic, signage, Chapter 10 may require a conditional use permit or home occupation approval.
