Roofing in Farmington, Michigan

Yes, a permit is required to replace a roof in Farmington, MI, issued by City of Farmington - Planning and Building Department. A reroof in Farmington is permit work: the department lists a dedicated Roofing Inspection Requirements sheet among its building forms, and the sheet says "All permit holders should schedule a rough inspection on the day the roof is to be started." It adds that "The inspector needs to inspect roof board or plywood replacement over 32 Sq Ft," that "Ice and Watershield or equivalent must be placed along the lowest portion of roof surfaces" to 24 inches inside the exterior wall line "in compliance with article 9 of the MRC," and that "Roof Venting must comply with the provisions of Article 8 of the MRC"; for the final inspection the roofer reports each attic area's square footage, whether ventilation is calculated at 1/150 or 1/300, the intake and exhaust vent area, and whether gable end vents exist and are closed off. The sheet still prints the City's older Liberty Street address. The City says "Anyone performing work requiring a building and/or trades permit must now apply online," through BS&A Online; contractors who are not registered email a contractor registration "AND a copy of your contractor's license." The building permit application asks for the "Value of Construction [(not cost) Contract Required]". The fee schedule prices "All Other Construction (Does not Include Plan Review Fees)" on the "Total Cost of Improvement": "To - $1,000" $50.00, then "$50.00 + $15 / $1,000 over $1,000". Inspections are booked online, and the department is open "Mon - Fri 8:30am - 4:30pm", phone 248-473-7250. This hub aggregates roofing permit and contractor-registration requirements for Farmington, Michigan, along with sourced roofing material references — every fact linked to its directory record.

Roofing permits & building code in Farmington

Roofing permit and contractor-licensing rules in Farmington are set locally by City of Farmington - Planning and 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." Locally, Section 7-1 of the Farmington Code of Ordinances designates the City's building inspectors as the enforcing agency and says "The city hereby assumes responsibility for the administration and enforcement of the Act throughout its corporate limits"; it names no code edition, and the City's Roofing Inspection Requirements sheet cites "the MRC".
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: Farmington registers contractors yearly: its fee schedule says "A current State License [PA 407 of 2016 or (equivalent- Detroit / Grand Rapids)] must be produced at time of registration / renewal", and its Contractor Registration form lists a $30.00 yearly building registration.
