Commercial Code Enforcement

The Commercial Enforcement Section is responsible for enforcing the building codes as they apply to all commercial businesses. New ordinances have been passed that impact Vacant Buildings.

Fire Code Violations

Existing buildings are inspected for compliance with fire codes and building safety codes. Many owners can avoid violations by learning what are the most commonly cited violations. Download our Common Fire Code Violation Brochure (DNS-149) for more information. 

There isn't a set amount for a single fire code violation. Under penalties or failure to comply (200-19), violations that are cited on a notice from our department an owner may be subjected to prosecution and to daily penalties of $150 to $10,000 in the manner provided in Section 200-19.

Occupancies with a high fire risk such as places of assembly and hazardous materials may require a Fire Prevention Permit.

Filling Stations

The City Clerk's Office issues annual operating licenses for all public filling stations: (414) 286-2238. However, the Milwaukee Health Department handles licenses and permits for food sales within filling stations: (414) 286-3521. Inspections are conducted in conjunction with the issuance of the license. The inspection encompasses fire safety, sanitation and the storage, handling and use of hazardous chemicals. A DNS-Commercial Section handled the inspections for the permits: (414) 286-3874.
