Waukesha, WI Home Business: Zoning & Home Occupation Permits (2026)

Home-based businesses in Waukesha are governed by Sec. 58(5) of the zoning code, which classifies a home occupation or professional home office as a permitted accessory use in every residential district, meaning no conditional use permit or Plan Commission hearing is required if the standards are met. The use has to stay clearly incidental and subordinate to the home's residential character and cannot take up more than 25 percent of the floor area of a single floor. It cannot be run out of a garage, shed or other accessory structure; it has to operate from inside the dwelling itself, with an entrance from within the home.

Staffing is limited to people who actually live in the house: no employee or contractor from outside the household may work on site. The Code lists examples of what qualifies, including babysitting, canning, crafts, desktop publishing, dressmaking, piano teaching, telephone marketing and word processing, and it separately lists occupations that never qualify regardless of scale, among them auto body or engine repair, firearm sales or repair, ammunition sales, barbering, beauty shops, construction trades, dance studios, firewood sales and processing, insurance agencies, pet sales and grooming, photographic studios and real estate brokerages.

Outdoor storage of equipment or product is prohibited, and no stock in trade may be kept or sold except goods made on the premises. A single unlit sign of no more than one square foot, mounted flat against the building, is the only signage allowed.
