Roofing permits & building code in Bay City

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

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 City of Bay City as its own building code enforcer, and City Code Section 26-41 designates the city's building official as the enforcing agency under the Michigan Residential Code without naming an edition. City Code Chapter 26 (Buildings and Building Regulations) was read in full; its only residential code text supplies flood hazard content for Table R 301.2(1) of the Michigan Residential Code.
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: Bay City sets no roofing contractor licence of its own; the Building Department's Applications & Forms page lists a Contractor Registration form. City Code Chapter 26 (read in full) sets no roofing contractor licence.
