Roofing permits & building code in Plymouth

Roofing permit and contractor-licensing rules in Plymouth are set locally by City of Plymouth, Minnesota - Building Inspection Division. Minnesota requires a state Residential Roofer (RR) license from the Department of Labor and Industry to contract residential roofing work — roofing is expressly excluded from the single-special-skill exemption other trades can use, and the only relief is an affirmative Certificate of Exemption for small operators — and the Minnesota State Building Code applies statewide, so a city cannot adopt different roofing-code provisions, only its own permit administration and fees — always confirm the current requirements with the authority before starting work.

Adopted building code
STATE-GOVERNED, NOT CITY-SET. Plymouth has no authority to adopt a different building code from the Minnesota State Building Code: Minn. Stat. § 326B.121, subd. 1(a)-(b) makes the State Building Code "the standard that applies statewide" and states it "supersedes the building code of any municipality," and subd. 2(c) bars a municipality from requiring "building code provisions regulating components or systems of any structure that are different from any provision of the State Building Code" by ordinance. The residential chapter is Minnesota Rules, Chapter 1309 ("Minnesota Residential Code"), which incorporates the 2018 International Residential Code (IRC) by reference "except as qualified by the applicable provisions in Minnesota Rules, chapter 1300, and as amended in this chapter" (Minn. R. 1309.0010, subpart 1), effective as the "2020 Minnesota Residential Code" published 2020-03-31. Plymouth, as a metro-area municipality that adopted the State Building Code before 2008, is required under Minn. Stat. § 326B.121, subd. 2(a) to continue administering and enforcing this same statewide code -- it has no local variance authority over code content. A Minnesota DLI consumer guidance sheet hosted on Plymouth's own website corroborates directly: "The 2020 Minnesota Residential Code adopts the 2018 International Residential Code (IRC)... The Minnesota State Building [Code] is the standard of construction for the entire state (Minnesota Statute 326B.121)." Per this repo's MN state-lever research (staging/burn-wave/MN_STATE_LEVER.md), cited here rather than re-derived.
Registration details
  • license: Minnesota has a statewide mandatory Residential Roofer (RR) license, per Minn. Stat. § 326B.805, subd. 1: "A person who meets the definition of a residential roofer as defined in section 326B.802, subdivision 14, must be licensed by the commissioner as a residential roofer, residential building contractor, or residential remodeler," enforced statewide (subd. 3) with a $15,000 gross-annual-receipts exemption threshold (subd. 6(5)) requiring an affirmative Certificate of Exemption. Roofing is explicitly excluded from the general single-special-skill exemption that applies to other trades (subd. 6(8)). Administered by MN DLI, not the City of Plymouth. Plymouth's own Residential Building Permit page states: "A permit is required to reroof a residence. Permits may be obtained by either the homeowner or a contractor who is licensed by the State of Minnesota, Department of Labor and Industry," and separately links out to "state residential contractor licensing information" rather than describing any city-specific license -- consistent with Plymouth imposing NO additional city-level contractor registration on top of the state RR license, but this is an inference from absence rather than an affirmative "no local license" statement, so flagged MODERATE-CONFIDENCE rather than fully confirmed.
