Madison, WI Home Business: Customer Traffic Restrictions (2026)

151's Home Occupation standards don't set a numeric cap on the number of customers who can visit, but they tightly constrain the kind of client-facing activity a home business can run, which is what actually limits foot traffic to a residential address. The occupation has to stay 'clearly incidental and secondary to the principal use of the dwelling for dwelling purposes,' protecting the residential character of the block. Only immediate family members residing on the premises, or other occupants of the dwelling, may work in the business unless the Plan Commission authorizes outside employees as a conditional use, a rule that limits staff, and by extension visitors and deliveries, arriving at the address.

The code bars a home occupation from doing on-site wholesaling, manufacturing or assembly, or running a limousine, towing, cartage or auto-service/repair business for any vehicle other than one registered to a resident, the businesses most likely to draw vehicle traffic. Retail sales are similarly restricted: no products may be kept or commodities sold other than those actually made on the premises, absent conditional use approval, and samples can be displayed but not sold. No more than 25% of one story's floor area may be devoted to the occupation, and the only exterior sign allowed is a non-illuminated nameplate no larger than two square feet, no larger sign to draw in walk-up customers. A home occupation run by a resident with a qualifying disability is exempt from several of these limits, including the sales and floor-area rules.
