Do you need a permit to replace a roof in Mount Vernon, IL?

Adopted code

City of Mt. Vernon Engineering and Inspections Office

Building permits in the City of Mt. Vernon, Illinois, in Jefferson County, are handled by the City's Engineering and Inspections Office at 1100 Main Street. The Illinois Capital Development Board says "The State has not adopted a building code for repairs to existing single family residences," so Mt. Vernon's roofing rules are its own. The City's own pages differ on the residential code: its building permit application names the 2021 International Residential Code, while its Building Codes page omits that code and says one- and two-family homes do not need to follow the codes it lists. This listing covers the office's contact details, the City's own statements on code and permits, and the rules state law sets for every Illinois roofer.

Registration details
  • state_level: Illinois licenses roofing contractors statewide with no dollar threshold. 225 ILCS 335/9(2): "No work involving the construction, reconstruction, alteration, maintenance, or repair of any kind of roofing or waterproofing may be done except by a roofing contractor or a qualifying party licensed or credentialed under this Act." Under 225 ILCS 335/5(a-3), "A municipality or a county that requires a building permit may not issue a building permit to a roofing contractor unless that contractor has provided sufficient proof of current licensure as a roofing contractor by the State," and a holder of a limited license is restricted to permits for work on residential properties of 8 units or less. The Illinois Department of Financial and Professional Regulation lists "Roofing Contractor, Licensed" among the professions it licenses.
Permit process note
The City's Building Permits page says "Many small repairs don’t need a building permit, but bigger projects often do" and that "All permitted work must be inspected." Its list of projects that need a permit names carports, garages, pools, storage buildings, new houses, mobile homes, new commercial construction and "Porches and decks that are over 30 inches high or have a roof," and adds "This is not a full list. If you are not sure whether your project needs a permit, contact the Engineering and Inspections Office for help." The page does not name roof replacement either way, so this listing does not state a yes or no answer for a re-roof. The City's building permit application has lines for a "Roofer" and "Roofer Address," and the page says permit fees "are based on the cost of the project."
Adopted code
THE CITY'S OWN PAGES CONFLICT ON THE RESIDENTIAL CODE. The City's Application for Building Permit has the applicant agree to build "in strict compliance with all provisions of the International Building Code, 2021 Edition; International Existing Building Code, 2021 Edition; International Residential Code for One and Two Dwellings, 2021 Edition," and says "Copies of the above Codes and Ordinances adopted by the City of Mt. Vernon are on file in the Office of the City Clerk." The City's Building Codes page, under "What Codes Do We Follow?," lists the "International Building Code (IBC) - 2021 Edition" and "International Existing Building code (IEBC) - 2021 Edition" but no residential code, and says "Exception: One- and two-family homes do not need to follow these codes." Chapter 150 of the City Code, Buildings, is hosted on American Legal Publishing and was not read for this listing, so it does not resolve which statement governs a house or whether the City has amended the IRC's roof provisions.
Sales & use tax
Illinois taxes the roofer, not the job, and the operative rate is not keyed to the Mt. Vernon job address. Under 86 Ill. Adm. Code 130.1940(c), a construction contractor "does not incur Retailers' Occupation Tax liability as to receipts from labor furnished and tangible personal property (materials and fixtures) incorporated into a structure," but "incurs Use Tax on the cost price of the tangible personal property that is incorporated into real estate," with "roofing materials" named in the rule's own list of examples. Repair and replacement are taxed identically: 130.1940(a)(3) defines "construct" to include "repair, renovate or remodel." The Illinois Department of Revenue states the Use Tax rate as "6.25% of the purchase price or fair market value, whichever is greater." Where the contractor buys for resale, the local tax follows "the place of business at or from which the contractor or builder handles the transaction" (130.2075(b)(3)), so the combined rate on materials is the supply house's or the contractor's, which this record does not pin down. The authoritative lookup is the Illinois Department of Revenue's MyTax Illinois Tax Rate Finder.
