Roofing in Sylvan Township (Washtenaw County), Michigan

Yes, a permit is required to replace a roof in Sylvan Township (Washtenaw County), MI, issued by Chelsea Area Construction Agency - Building Permits for Sylvan Township. In Sylvan Township the building permit comes from the Chelsea Area Construction Agency, not from the township: the township's Planning & Zoning page says "Upon receiving zoning permit approvals from Sylvan Township, it is essential to collaborate with CACA to obtain a building permit", and the Agency's FAQ answers "Do I need a building permit for a roofing job, siding replacement, or a window replacement?" with "Yes, after contacting your township, print out an Instant Building Permit App and submit it." The township's Planning & Zoning page lists "Projects that do not require a Zoning Permit" include "Roofing or siding replacement that does not expand the building envelope", which is a zoning permit statement and leaves the building permit to the Agency, so a roofer should ask the township whether a zoning permit is needed and apply to the Agency for the building permit. The Agency's FAQ says "Under normal circumstances, the permit can be issued the next business day" and that the inspector can usually do an inspection "the next business day"; its fee schedule (2.24.2025) lists an application fee of $30.00 and says "In the event that construction activities have begun prior to the issuance of a permit, the applicant is subject to working without a permit fee of $100.00 Residential/$130.00 Commercial." The Agency's home page shows building inspections Monday through Friday, 8:30 to 11:30, by calling 734-475-4420, and office hours of Monday through Thursday 7:00 AM to 3:30 PM and Friday 7:00 AM to 1:00 PM. The Agency's FAQ says it accepts cash or check, while its home page says credit and debit cards are now accepted. Separate applications are needed for plumbing, mechanical and electrical work. The Agency also covers the City of Chelsea and Dexter, Lima and Lyndon Townships. Sylvan Township's offices are at 18027 Old US 12, Chelsea, MI 48118, 734-475-8890.

Roofing permits & building code in Sylvan Township (Washtenaw County)

Roofing permit and contractor-licensing rules in Sylvan Township (Washtenaw County) are set locally by Chelsea Area Construction Agency - Building Permits for Sylvan Township. 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." The State of Michigan's Statewide Jurisdiction List names the Township of Sylvan (Washtenaw County) as its own building code enforcer. Section 8-19 of the township's Code of Ordinances (codified through Ord. No. 24-04, adopted August 13, 2024) designates the building official as the enforcing agency "Pursuant to the provisions of the state construction code" and names no edition, with an editor's note in the posted code reading "The state construction code is currently being enforced by CACA." The Agency's home page says its members "have adopted the Michigan Building Codes" without naming an edition. None of the township or Agency instruments read names an older dwelling code edition.
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 Agency's building permit application asks for the contractor's "BUILDERS LICENSE NUMBER", and neither the Agency's pages nor Chapter 8 of the Sylvan Township Code of Ordinances publish a contractor registration or licence of their own. This record does not decide whether a given roofer falls inside a state exemption.
