Roofing permits & building code in Trowbridge Township (Allegan County)

Roofing permit and contractor-licensing rules in Trowbridge Township (Allegan County) are set locally by Township of Trowbridge - Building Permits. 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.

Roofing permit
Required
Contractor registration
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." LARA's Statewide Jurisdiction List names the Township of Trowbridge as its own building code enforcer. Township Ordinance No. 2018-2 (adopted 6/7/18) says "the Township of Trowbridge has assumed responsibility for the administration and enforcement of the State Construction Code" and designates violations of it as municipal civil infractions; it names no code edition, and neither the township's Forms & Permits page nor the permit office's requirements sheet and application names a residential code edition.
