Housing and Building Standards Michigan 3 Minutes Read · published March 08, 2026 Flag of Michigan

Troy, Michigan regulates accessory dwelling units (ADUs), elevator safety, lead hazards and energy-code compliance through its Building Division, Planning and Code Enforcement teams and applicable state rules. This guide explains typical permit paths, inspection and complaint routes, where to find official forms, and what to expect for enforcement and appeals in Troy.

ADU Permits and Zoning

ADUs and accessory structures usually require zoning review and building permits. In Troy this begins with the Community Development/Building Division for plan review and the Planning Division for zoning confirmation. Before applying, confirm lot and use standards in the Troy Zoning Ordinance and the Building Division submittal checklist.

Check zoning and lot standards with Planning before preparing construction drawings.

Elevator Safety and Inspections

Elevator installations, periodic inspections and equipment registration follow the Michigan elevator and conveyance statutes and are enforced locally by the Building Division coordinated with state inspectors when required. Property owners must keep certificates of inspection and arrange required tests before placing equipment into service.

Lead, Renovation and Hazard Rules

Lead-based paint hazards, renovations in pre-1978 housing, and tenant-protection obligations are addressed by federal and state rules; local enforcement is coordinated through Troy's health and building contacts. Contractors performing renovation, repair or painting may need to follow certification or notification requirements under federal/state programs.

Energy Code and Efficiency Requirements

New construction and major alterations must meet applicable state energy codes adopted by Michigan; Troy enforces those requirements during plan review and inspections through the Building Division.

Penalties & Enforcement

Enforcement for building, zoning, elevator, lead or energy-code violations is handled by the City of Troy Building Division, Planning/Code Enforcement and related offices. Complaints are processed through the City's permit and code enforcement workflow and may result in administrative orders, re-inspections, withheld certificates of occupancy or legal action.
