How Detroit Handles Home Business: A Practical Guide
Detroit maintains 197 local ordinances across all categories, and 6 of those deal specifically with home business. Here is a breakdown of what the city actually requires, what is prohibited, and where Detroit falls on the strict-to-permissive spectrum compared to other cities.
Zoning Restrictions
Detroit allows home occupations as a permitted accessory use in residential zoning districts under Detroit City Code Chapter 50 (Zoning), Article XII (Use Regulations), Division 5 (Accessory Uses). Approval is administered by the BSEED Zoning and Special Land Use Division and requires the occupation to be clearly incidental and subordinate to the dwelling's residential use, conducted entirely within the dwelling by members of the household, generating no external evidence of the business (no outside storage, no commercial signage beyond a small permitted nameplate, no significant customer or vehicular traffic, and no on-premises sales of stock). Certain uses (e.g., auto repair, kennels, restaurants, medical or dental offices serving the public, and manufacturing) are categorically prohibited as home occupations regardless of conditions.
Key details: Code Chapter: Detroit City Code Chapter 50 (Zoning). Article / Division: Article XII (Use Regulations), Division 5 (Accessory Uses). Use Classification: Accessory to permitted residential use; clearly incidental and subordinate. Where Conducted: Entirely within the dwelling unit, by household members. External Evidence: Prohibited - no commercial signage beyond small nameplate, no outside storage.
Operating a non-compliant home occupation in a residential district is a Chapter 50 zoning violation enforceable by BSEED Zoning and Special Land Use Division through notices of violation, administrative adjudication at the Department of Administrative Hearings, and civil fines. The City may also pursue injunctive relief in Wayne County Circuit Court to abate persistent commercial operations from a residential dwelling. Categorically prohibited uses (auto repair, on-premises restaurant operation, commercial kennels, etc.) cannot be cured by application; they must cease. Where the operation also lacks the required City of Detroit business license, the Office of the City Clerk and the Law Department may pursue parallel enforcement. Where the operation produces noise, traffic, or other off-site impacts, neighbors may file complaints with BSEED that build into a compliance file used for enforcement and any future zoning grant or variance application.
