Milwaukee does not require owner-occupancy for ADU properties under Chapter 295. Property owners may build an ADU and rent both units to separate tenants. Wisconsin has no state preemption on owner-occupancy (unlike California's AB 671). Condominium and HOA covenants under Wisconsin Statutes Chapter 703 (Condominium Ownership Act) may impose owner-occupancy.
Milwaukee Chapter 295 Subchapter 5 does not condition ADU permits on owner residency. The city's 2019 zoning revisions deliberately omitted owner-occupancy requirements to maximize housing flexibility. Property owners may construct an ADU on rental property, sell with the ADU intact, and lease both units to separate tenants. Wisconsin has not enacted state-level ADU preemption legislation comparable to California, Oregon, or Washington. Private restrictions remain: condominium declarations under Wisconsin Statute 703 (Condominium Ownership Act) and homeowner association covenants under common law contract principles may impose owner-occupancy. Wisconsin courts uphold reasonable covenants in declarations. Most Milwaukee single-family neighborhoods (Bay View, Riverwest, Sherman Park, Washington Heights) are fee-simple without HOAs. Newer subdivisions and condominium conversions are more likely to have covenants.
No city enforcement of owner-occupancy. HOA/condo association violations result in declaration-based fines, typically $50-$500 per violation, with lien rights for unpaid assessments. Civil litigation in Milwaukee County Circuit Court is available for declaration enforcement.
