Roofing permits & building code in Bloomington

Roofing permit and contractor-licensing rules in Bloomington are set locally by City of Bloomington, Minnesota - Building and Inspections 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. Bloomington 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. Bloomington, 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. 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)) that still requires an affirmative Certificate of Exemption from the state, not an automatic pass. Roofing is explicitly excluded from the general single-special-skill exemption that applies to other trades (subd. 6(8)). This is administered by MN DLI, not the City of Bloomington. CITY LAYER -- CONFIRMED, NO ADDITIONAL ROOFING LICENSE: Bloomington's own "Contractor licensing and testing" page (fetched directly) states the city's local licensing/testing regime is scoped to MECHANICAL TRADES ONLY: "The Building and Inspection Division licenses mechanical trade contractors annually and conducts quarterly trade testing," and lists the covered trades as Gas Installer Class A, HVAC, Hot Water/Steam, Oil Burner, and Refrigeration -- roofing is not among them. Bloomington's FAQ page separately confirms: "most residential building contractors, re-modelers, roofers and manufactured home installers obtain state licenses" (through MN DLI), while only "mechanical, HVAC, and gas-related work in Bloomington must obtain a contractor license through the Building and Inspections division." Bloomington therefore imposes NO additional city-level roofing contractor license on top of the state RR license.
