Wauwatosa's Home Business: The Rules That Matter

Every city handles home business a little differently. In Wauwatosa, Wisconsin, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Zoning & Home Occupation Permits

Wauwatosa allows home occupations as an accessory use to a residential dwelling under Wauwatosa Municipal Code § 24.10.020, but the business must stay subordinate to the home's residential character. The owner must live in the dwelling, all work and storage must happen inside a fully enclosed building, and no exterior alterations, signage, or window displays that look commercial are allowed.

Key details: Governing section: § 24.10.020. Owner residency: Must reside in the dwelling. Work location: Confined to a completely enclosed building. Signage/displays: No window or public merchandise display. Exempt uses: Home day cares, bed & breakfasts.

A home occupation that breaks these standards is a zoning violation under § 24.17.020: the zoning administrator can order the violation corrected within 10 days, then withhold or revoke building and business permits, issue a stop-work order, or seek a court injunction or abatement. Each day a violation continues after notice counts as a separate offense, and the property owner, tenant, and any assisting contractor can each be cited.

Customer Traffic Restrictions

Wauwatosa caps every home occupation at three people on site at once, including the resident owner. Under Wauwatosa Municipal Code § 24.10.020, up to two nonresident employees, associates or customers may be present at any time, and that cap applies to the whole property regardless of how many home businesses are being run there.

Key details: Max on-site persons: 3 total (owner plus 2). Cap applies: Per property, not per business. Delivery hours: 8:00 a.m. to 7:00 p.m.. Delivery vehicles: No semi-tractor trailers.

Exceeding the three-person limit or accepting deliveries outside the 8:00 a.m. to 7:00 p.m. window is a zoning violation of § 24.10.020, enforced by the zoning administrator under § 24.17.020. The city can issue a correction notice with 10 days to comply, then withhold or revoke permits, stop work, or seek a court injunction; each day the violation continues after notice is a separate offense.

Home Daycare

Wauwatosa allows a home-based day care serving up to 8 children or adults as a permitted, by-right accessory use in every residential zoning district, no conditional use permit needed. Care for more than 8 requires conditional use approval under Section 24.16.040, and the use is exempt from the city's separate home occupation rules.

Key details: Governing sections: Sec. 24.08.030 definition, Sec. 24.07.030 use table. Up to 8 people: Permitted by right in all residential districts. Over 8 people: Conditional use permit required, Sec. 24.16.040. Home occupation rules: Do not apply, exempted under Sec. 24.10.020. Last amended: Ord. O-25-25, effective 11/18/2025.

Operating a home-based day care for more than 8 children or adults without first obtaining a conditional use permit under Section 24.16.040 puts the operator out of compliance with the district's use table; the Zoning Administrator can require the operator to seek approval or cease operating the oversized use. A zoning violation is separate from, and does not excuse noncompliance with, the state day care licensing requirements Wisconsin administers outside the city code.

The Bottom Line

Wauwatosa's home business rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Wauwatosa is broadly strict or permissive.

These rules come from Wauwatosa's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
