Roofing permits & building code in Ypsilanti

Roofing permit and contractor-licensing rules in Ypsilanti are set locally by City of Ypsilanti - Building Department. Michigan licenses residential roofers at the state level — the Occupational Code’s residential maintenance and alteration contractor licence names roofing among its trades, with exemptions that include a job whose whole contract price is under $600 — and some cities add a local contractor registration on top, while the Michigan Residential Code applies throughout the state, so a city, village, township or county enforces the state code rather than writing its own roofing rules — always confirm the current requirements with the authority before starting work.

Required
Adopted building code
2015 Michigan Residential Code. This is state law and it is the same in every Michigan city, village, township and county: the state construction code act says "This act and the code apply throughout the state," and the Michigan Residential Code rule adopts "the international residential code, 2015 edition" with the state amendments in R 408.30500 to R 408.30547g. A 2021 edition was filed with the secretary of state in 2025 but has not taken effect. On July 7, 2025 the Michigan Court of Claims entered a stipulated order in Home Builders Assoc et al. v LARA et al., and the Michigan Department of Licensing and Regulatory Affairs (LARA) says that while that order remains in place "the 2015 versions of the IRC and residential provisions of the IECC standards currently adopted, in part, by each rule set will remain valid and in effect." The City of Ypsilanti's Code of Ordinances, Section 18-51, designates the building inspector and designees as the building official and says "The city hereby assumes responsibility for the administration and enforcement of the state building code, the state plumbing code and the state mechanical code throughout its corporate limits." The Building Department's Work Exempt from Permits sheet reprints Section R105 of the "2015 Michigan Residential Code". Chapter 18 of the Code of Ordinances (Buildings and Building Regulations, Articles I to VI, Sections 18-1 to 18-228, read in full in Municode Supplement 16, codified through Ordinance No. 1456, December 9, 2025) adopts no residential code edition of its own; it adopts the "International Property Maintenance Code, 2018 edition" (Section 18-91) and repeals the city's earlier adoption of a National Electrical Code edition (Section 18-71).
Registration details
  • state_level: Michigan licenses residential maintenance and alteration contractors under the Occupational Code, and that licence "includes the following crafts and trades" among which it names roofing (MCL 339.2404(3)); "A person shall not engage in or attempt to engage in the practice of an occupation regulated under this act" without the licence (MCL 339.601(1)). MCL 339.2403 lists who may work without one, including a project whose "aggregate contract price for the labor, material, and any other items for the undertaking or project is less than $600.00". This record does not decide whether a given roofer falls inside an exemption.
  • city_level: The city's Contractor Registration Form says it "is to be completed by state-licensed contractors, architects, engineers, and design professionals prior to applying for permits", asks for the contractor's licence number and expiration date, workers' compensation carrier, federal ID and MESC employer number, and says "A COPY OF YOUR STATE ISSUED CONTRACTOR AND DRIVER'S LICENSE/PHOTO I.D. MUST BE SUBMITTED WITH THIS APPLICATION." The pages read for this record name no separate city contractor licence or bond for roofers.
