City of Hudson - City Office (Building Permits)

Yes, a permit is required to replace a roof in Hudson, MI, issued by City of Hudson - City Office (Building Permits). The City of Hudson has published nothing that names roof work. Its Codes and Permits page, read October 15, 2026, links a Building Permit, Mechanical Permit, Electrical Permit and Plumbing Permit and says "All Building Permits must be pulled through the City Office". The Building/Zoning Permit Application asks for the owner, the job site address, the contractor, a builder's license number and expiration date, a liability insurance policy number, a "DESCRIPTION OF WORK:", an "ESTIMATED VALUATION OF ALTERATIONS OR IMPROVEMENTS:" and, for new buildings, lot and setback data, and says "The City reserves the right to require architectural or residential stamped blueprints for any proposed building." The application shows no fee. Section 5-27 of the Code of Ordinances (Chapter 5, codified through Ordinance No. 409-25) says fees "shall be established from time to time by resolution of the city council" and "This schedule shall be available to the public from the city clerk.", and no fee schedule is posted on the pages read, so ask the City Office for the current fee. The application directs questions to the Hillsdale County Inspection & Environmental Services Department at 33 McCollum St., Hillsdale, 517-437-4130, and the city's plumbing permit application says to call 517-437-4130 for inspections with 72 hours notice. The City Office is at 121 N. Church Street, Hudson, MI 49247, phone 517-448-8983, and the page gives no office hours. The City of Hudson's page names no code edition. The Township of Hudson in Lenawee County is a separate unit on the state's list and is not covered by this record.

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 City of Hudson publishes no contractor registration of its own. Its Building/Zoning Permit Application asks the contractor for a builder's license number and expiration date and a liability insurance policy number, and repeats Section 23a of the State Construction Code Act, which prohibits a person from conspiring to circumvent the licensing requirements of this state relating to persons who are to perform work on a residential building or a residential structure.
Permit process note
The City of Hudson has published nothing that names roof work. Its Codes and Permits page, read October 15, 2026, links a Building Permit, Mechanical Permit, Electrical Permit and Plumbing Permit and says "All Building Permits must be pulled through the City Office". The Building/Zoning Permit Application asks for the owner, the job site address, the contractor, a builder's license number and expiration date, a liability insurance policy number, a "DESCRIPTION OF WORK:", an "ESTIMATED VALUATION OF ALTERATIONS OR IMPROVEMENTS:" and, for new buildings, lot and setback data, and says "The City reserves the right to require architectural or residential stamped blueprints for any proposed building." The application shows no fee. Section 5-27 of the Code of Ordinances (Chapter 5, codified through Ordinance No. 409-25) says fees "shall be established from time to time by resolution of the city council" and "This schedule shall be available to the public from the city clerk.", and no fee schedule is posted on the pages read, so ask the City Office for the current fee. The application directs questions to the Hillsdale County Inspection & Environmental Services Department at 33 McCollum St., Hillsdale, 517-437-4130, and the city's plumbing permit application says to call 517-437-4130 for inspections with 72 hours notice. The City Office is at 121 N. Church Street, Hudson, MI 49247, phone 517-448-8983, and the page gives no office hours. The City of Hudson's page names no code edition. The Township of Hudson in Lenawee County is a separate unit on the state's list and is not covered by this record.
Adopted 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 Hudson as its own building code enforcer. Section 5-26 of the city's Code of Ordinances (codified through Ordinance No. 409-25, enacted July 15, 2025) adopts "The state construction code as established by Act No. 230 of the Public Acts of Michigan of 1972 (MCL 125.1501 et seq.), as amended" and names no edition, and Section 5-27 designates the building official as the enforcing agency. Article IV of the same chapter adopts the International Property Maintenance Code, also without a stated edition, which is not a dwelling code. The City Office page and permit forms name no code edition.
Drip edge
Required — Required on asphalt shingle roofs by state law. Michigan makes no amendment to the drip edge rule of the 2015 International Residential Code, Section R905.2.8.5, which applies as published: "A drip edge shall be provided at eaves and rake edges of shingle roofs." Segments overlap by at least 2 inches, the drip edge extends at least 1/4 inch below the roof sheathing and at least 2 inches back onto the deck, it is fastened at no more than 12 inches on center, and underlayment goes over it at the eaves and under it at the rakes. A reroof is held to the same rule, because "Materials and methods of application used for re-covering or replacing an existing roof covering shall comply with the requirements of Chapter 9" (R908.1). The City of Hudson Codes and Permits page, its Building/Zoning Permit Application and Chapter 5 of its Code of Ordinances were read for a local rule and state nothing further on drip edge. About drip edge
Ice & water shield
Required — Required everywhere in Michigan by state law. Michigan fills in the climatic design table of the 2015 code once for the whole state (Rule 516, Table R301.2(1)), and its ice barrier underlayment column reads Yes. The state footnote calls for Yes "for areas where the average daily temperature in January is 25 degrees Fahrenheit" or less, or where ice damming has caused damage. The base code then requires an ice barrier "for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate and slate-type shingles, wood shingles and wood shakes," running "from the lowest edges of all roof surfaces to a point not less than 24 inches (610 mm) inside the exterior wall line of the building" (R905.1.2). Detached accessory structures without conditioned floor area are exempt. On a tear-off, an existing ice barrier that is adhered to the deck may stay and be covered with an additional layer (R908.3, Exception). The City of Hudson Codes and Permits page, its Building/Zoning Permit Application and Chapter 5 of its Code of Ordinances were read for a local rule and state nothing further on ice barrier. About ice & water barrier
Impact-resistant roofing
Not required — No impact-resistance requirement under state law. The 2015 Michigan Residential Code was searched in full and has no hail or impact rating rule for roof coverings: the words hail, impact and UL 2218 do not appear in it, and none of them appears in the roof assemblies chapter of the base 2015 International Residential Code either. Michigan applies one code statewide ("This act and the code apply throughout the state."), and the act gives the power to amend it to the state director, who adopts the model codes "with amendments, additions, or deletions as the director determines appropriate." The City of Hudson Codes and Permits page, its Building/Zoning Permit Application and Chapter 5 of its Code of Ordinances were read for a local rule and state no impact rule.
Repair permit threshold
The City of Hudson publishes no size, area or cost threshold for roof work and nothing that names reroofing. Its Codes and Permits page lists a Building Permit, a Mechanical Permit, an Electrical Permit and a Plumbing Permit and says "All Building Permits must be pulled through the City Office". Its Building/Zoning Permit Application asks for a "DESCRIPTION OF WORK:" and an "ESTIMATED VALUATION OF ALTERATIONS OR IMPROVEMENTS:" and has no roofing item, and the city's building chapter (Chapter 5, Buildings and Building Regulations) adopts "The state construction code as established by Act No. 230 of the Public Acts of Michigan of 1972 (MCL 125.1501 et seq.), as amended" without naming roof work. The city has published nothing applying the state's ordinary-repairs relief to a reroof, so the state's general permit rule applies to one. Under state law, "A building permit is not required for ordinary repairs of a building or structure." (MCL 125.1510), without a definition of ordinary repairs. Ask the City Office (517-448-8983) before starting a roof job.
Roof layer limit / recover
Two layers at most, under state law. Michigan builds one- and two-family homes to the 2015 Michigan Residential Code, which adopts the 2015 International Residential Code and makes no amendment to its reroofing section, Section R908; the Michigan rule set was searched in full and R908 does not appear in it. The base section therefore applies as the International Code Council publishes it. Section R908.3.1.1 lists the conditions under which a new roof may not be laid over an existing one, and the third is "Where the existing roof has two or more applications of any type of roof covering." One existing layer may be covered once; a roof that already carries two layers is torn off to the deck. The same section also bars covering a roof that is water soaked or too deteriorated to serve as a base, and covering "slate, clay, cement or asbestos-cement tile." Locally, Chapter 5 of the City of Hudson Code of Ordinances (Buildings and Building Regulations), codified through Ordinance No. 409-25, was read in full on Municode: Article I In General, Article II Construction Code, Article III Dangerous Structures, Article IV Property Maintenance Code and Article V Inspection of Rental Property. It adopts the state construction code, designates the enforcing agency, sets fees by council resolution and adopts the International Property Maintenance Code with amendments; it has no reroofing provision and amends nothing in Section R908. The City Office page and permit forms state no layer rule.
Deck & sheathing requirements
State law, from the base code. Michigan makes no amendment to the roof sheathing section of the 2015 International Residential Code, Section R803, which does not appear in the Michigan rule set, so it applies as published. Lumber roof sheathing follows Table R803.1: over rafters or beams 24 inches apart it must be at least 5/8 inch net thick. Wood structural panels must be identified "for grade, bond classification and performance category by a grade mark or certificate of inspection issued by an approved agency," and their spans may not exceed "the values set forth in Table R503.2.1.1(1), or APA E30." For a shingle roof the base code adds that "Asphalt shingles shall be fastened to solidly sheathed decks" (R905.2.1), and on any reroof "The structural roof components shall be capable of supporting the roof covering system" (R908.2). The City of Hudson Codes and Permits page, its Building/Zoning Permit Application and Chapter 5 of its Code of Ordinances were read for a local rule and state nothing further on roof sheathing.
Sales & use tax
6%, statewide, with no local add-on. This is state law: the General Sales Tax Act sets the tax "equal to 6% of the gross proceeds of the business," the Use Tax Act sets "a total combined rate equal to 6%," and the Michigan Department of Treasury says "Michigan does not allow city or local units to impose sales tax." On a roofing job the roofer is the taxpayer on materials, because the Use Tax Act counts as a consumer "A person acquiring tangible personal property if engaged in the business of constructing, altering, repairing, or improving the real estate of others." Nothing on the City of Hudson Codes and Permits page changes this.
