Roofing permits & building code in Rochester

Roofing permit and contractor-licensing rules in Rochester are set locally by City of Rochester - 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.

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." Locally, the City's Codes in Effect sheet lists "2015 Michigan Residential Code - Effective April 20, 2017" for residential work, and Section 10-33 of the Rochester Code of Ordinances adopts the state construction code "as all of the codes may be amended from time to time by the state"; neither names a different residential edition.
