In the City of Northville, building permits are applied for online: the Inspections & Online Permits page links "Apply for a permit online" to the city's BS&A Online portal and says "Inspection requests for the next business day must be scheduled by 3:30 pm."

Roofing permits & building code in Northville

Roofing permit and contractor-licensing rules in Northville are set locally by City of Northville - Building Division (Community Development). 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
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 Northville as its own building code enforcer. Northville's codified Code of Ordinances Sec. 14-186 (Ord. No. 6-18-01, § 6, 7-2-01; Ord. No. 02-17-09, § 1, 3-2-09) adopts "Michigan Residential Code, effective date July 31, 2001"; this directory has not read that text, and whether the codified reference has any effect today is not decided here. This record states the 2015 Michigan Residential Code, which the state construction code act applies throughout the state ("This act and the code apply throughout the state," MCL 125.1508a) and which LARA says remains in effect while the Court of Claims order of July 7, 2025 stands. Northville has published no statement naming the edition it enforces; its Community Development page, read October 12, 2026, says it enforces "the adopted Michigan Building Code and Michigan Residential Code". The same section adds "or as subsequently amended by the Michigan Bureau of Construction Codes", and Sec. 14-31 adopts a Michigan Building Code with the same July 31, 2001 effective date.
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 Inspections & Online Permits page asks contractors to register for the BS&A Online contractor inspection portal and link the account to the City of Northville with a pin sent in a contractor letter; the page describes no separate city contractor licence, and none was found in the Code of Ordinances chapters read.
