Do you need a permit to replace a roof in Lakeville, MN?

Adopted code

City of Lakeville, Minnesota - Building Inspections Division

Yes — a permit is required to replace a roof in Lakeville, MN, issued by City of Lakeville, Minnesota - Building Inspections Division. Lakeville accepts residential roofing (re-roof) permit applications online through the city's BS&A permitting system (homeowner and contractor portals) or via a signed paper Building Permit Application. Lakeville's own Residential Re-Roofing Guide (revised 9/30/16) sets out a permit checklist and general building code requirements for asphalt shingle re-roofs, and requires only a single final inspection ("to verify proper venting, flashing and installation"), scheduled by calling 952-985-4440 with at least 24-hour advance notice; access into the home is not required for the final inspection. An Inspection Record card must remain visible from the street until the final inspection is complete. A state-issued roofing contractor license is required for contractors performing the work; Lakeville does not impose an additional city-level roofing or building-contractor license.

Registration details
  • license: Minnesota has a statewide mandatory Residential Roofer (RR) license, per Minn. Stat. 326B.805, subdivision 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 with a $15,000 gross-annual-receipts exemption threshold (subd. 6, clause (5)) requiring an affirmative certificate of exemption from the commissioner. Administered by MN DLI, not the City of Lakeville. Lakeville's own Residential Re-Roofing Guide states directly, in its PERMIT CHECKLIST, that "state license is required for roofing contractors." Lakeville's own business-licensing page (Applications & Business Licensing) lists only Home Occupation, Massage Therapy Center, Massage Therapy, Mobile Food Unit, Liquor, and Tobacco Products as categories requiring a city license, and states: "The City of Lakeville requires licenses for only certain types of businesses. If your type of business is not listed, please work with the State of Minnesota to obtain proper business licensing." Roofing and general building contracting are not among Lakeville's own licensed categories, consistent with Lakeville imposing no additional city-level roofing-contractor registration on top of the state RR license.
Permit process note
Lakeville accepts residential roofing (re-roof) permit applications online through the city's BS&A permitting system (homeowner and contractor portals) or via a signed paper Building Permit Application. Lakeville's own Residential Re-Roofing Guide (revised 9/30/16) sets out a permit checklist and general building code requirements for asphalt shingle re-roofs, and requires only a single final inspection ("to verify proper venting, flashing and installation"), scheduled by calling 952-985-4440 with at least 24-hour advance notice; access into the home is not required for the final inspection. An Inspection Record card must remain visible from the street until the final inspection is complete. A state-issued roofing contractor license is required for contractors performing the work; Lakeville does not impose an additional city-level roofing or building-contractor license.
Adopted code
STATE-GOVERNED, NOT CITY-SET. Under Minn. Stat. 326B.121, subd. 1(a)-(b), "the State Building Code is the standard that applies statewide" and "supersedes the building code of any municipality," and subd. 2(c) bars a municipality from imposing building code provisions that differ from the State Building Code. That code is Minn. Rules ch. 1309, the "Minnesota Residential Code," which under Minn. R. 1309.0010, subpart 1 incorporates by reference the 2018 edition of the International Residential Code, "except as qualified by the applicable provisions in Minnesota Rules, chapter 1300, and as amended in this chapter." Lakeville's Building Inspections Division administers this code through its own permitting and inspection process (see roofing_permit_required). Lakeville's own local Building Code chapter (City Code, Title 9, Chapter 1, "City Building Code") is hosted at codelibrary.amlegal.com, which returned a Cloudflare bot-challenge to every fetch attempt this session (curl with a browser user agent, wget, curl with full Chromium client-hint headers, and the WebFetch tool all returned HTTP 403); no independent city-level code edition or amendment content is asserted here as a result.
Drip edge
Not required — STATE-GOVERNED, NOT CITY-SET. Minnesota Rules part 1309.0905, subpart 2 states in full: "IRC section R905.2.8.5. Section R905.2.8.5 is deleted in its entirety" -- the base IRC drip-edge requirement has no force anywhere in Minnesota, including Lakeville, and under Minn. Stat. 326B.121, subd. 2(c) Lakeville has no authority to reinstate a drip-edge requirement beyond this state baseline. Lakeville's own Residential Re-Roofing Guide illustrates drip-edge installation technique in its diagrams (eave and rake drip edge, shingle overhang) but its "GENERAL BUILDING CODE REQUIREMENTS" checklist -- the section that states the guide's actual mandates -- contains no bullet mandating drip-edge installation. About drip edge
Ice & water shield
Required — Lakeville's Residential Re-Roofing Guide states, under "GENERAL BUILDING CODE REQUIREMENTS": "Ice and water protection shall comply with ASTM D 1970 and be provided at the eves extending 24 inches inside the exterior wall line. Not required on detached unheated structures. Existing membrane may remain in place but must be covered with new." This mirrors the statewide requirement built into Minnesota Rules part 1309.0301, subpart 2 (amending IRC Table R301.2(1) to pre-fill "Yes" for ice barrier underlayment statewide). Lakeville's own document supplies the garage/outbuilding nuance: ice-and-water protection is not required on detached unheated structures. About ice & water barrier
Mid-roof inspection
Not required — Lakeville's Residential Re-Roofing Guide lists a single item under "REQUIRED INSPECTIONS": "Final inspection: When complete to verify proper venting, flashing and installation." No interim, mid-roof, or sheathing/underlayment inspection is listed anywhere in the two-page guide -- only the final inspection.
Impact-resistant roofing
Not required — Minn. Stat. 326B.121, subd. 1(a)-(b) makes the State Building Code the standard that applies statewide and supersedes the building code of any municipality, and subd. 2(c) bars a municipality from imposing building code provisions for a component or system that differ from the State Building Code. Minnesota Rules chapter 1309's table of parts (read in full) amends IRC Chapter 9 in exactly two places -- part 1309.0903 (kick-out flashing) and part 1309.0905 (asphalt-shingle sheathing and drip-edge deletion) -- neither of which addresses impact resistance, hail, UL 2218, or Class 4; no part exists amending IRC Section R902 (Fire Classification) either. Locally, Lakeville's own Residential Re-Roofing Guide (read in full, two pages) contains no mention of "UL 2218," "Class 4," "impact," or "hail" anywhere in its permit checklist or general building code requirements.
Repair permit threshold
NO MINIMUM-SIZE OR COST THRESHOLD FOUND. Lakeville's Residential Re-Roofing Guide states, under "PERMIT CHECKLIST": "Signed completed Building Permit Application or obtain permit online, state license is required for roofing contractors. Permits are required for re-roofs." No square-footage or dollar-value carve-out for small repairs appears anywhere in the two-page guide. Treat Lakeville as requiring a permit for re-roofing work of any size, and confirm any borderline small repair with Building Inspections at 952-985-4440.
Wind design criteria
STATE-GOVERNED, NOT CITY-SET -- applies identically in Lakeville as everywhere else in Minnesota because Lakeville administers, but does not independently set, the Minnesota State Building Code (Minn. Stat. 326B.121, subd. 1(a)-(b), 2(c)). Minnesota Rules part 1309.0301, subpart 2 amends IRC Table R301.2(1) ("Climatic and Geographic Design Criteria") to read, for the Wind Design column: ultimate design wind Speed 115 mph, Topographic effects "YES," and Seismic Design Category "A" -- uniform statewide values built into the table itself. The same table pre-fills "Yes" for "ICE BARRIER UNDERLAYMENT REQUIRED." Ground snow load, one of the few geographically-varying inputs on the table, is fixed by Minnesota Rules part 1303.1700: Dakota County (Lakeville) is not among that rule's enumerated 60-psf counties, so it falls under the rule's statewide default ground snow load of 50 pounds per square foot.
Roof layer limit / recover
Lakeville's Residential Re-Roofing Guide states, under "GENERAL BUILDING CODE REQUIREMENTS": "Existing roofing shall be torn off prior to installing the new roof where the existing roof has deteriorated to a point that the existing roof is not adequate as a base or there are two or more applications of any type of roof covering." In practice this limits a roof to two layers of covering before a full tear-off is required. Minnesota Rules chapter 1309's own table of parts amends IRC Chapter 9 in exactly two places (1309.0903 kick-out flashing and 1309.0905 sheathing/drip-edge) and contains no separate statewide layer-count rule, so this two-layer/tear-off standard rests on Lakeville's own guide rather than a numbered state rule.
Deck & sheathing requirements
Lakeville's Residential Re-Roofing Guide states, under "GENERAL BUILDING CODE REQUIREMENTS": "Decking for asphalt shingles shall be solidly sheathed or 1 inch thick nominal wood boards. Damaged or deteriorated decking shall be replaced." This matches Minnesota Rules part 1309.0905, subpart 1, which amends IRC Section R905.2.1 statewide to read: "Asphalt shingles shall be fastened to solidly sheathed decks or 1-inch thick nominal wood boards." Lakeville's guide adds a local instruction that damaged or deteriorated decking must be replaced.
Sales & use tax
8.125% combined rate for the City of Lakeville, per the Minnesota Department of Revenue's official "Local Sales and Use Tax Rate Guide" (effective 7/1/2026-9/30/2026), Dakota County table, "Lakeville" row: Other (Metro) Area Rate 1.00% -- the Metro Area Sales and Use Tax for Housing (0.25%) plus the Metro Area Transportation Sales and Use Tax (0.75%), which the guide states apply "to taxable sales and purchases made in the seven-county Twin Cities area: Anoka, Carver, Dakota, Hennepin, Ramsey, Scott, and Washington counties" -- plus a 0.25% Dakota County Transit Rate, plus the 6.875% State Rate, with no separate Lakeville city rate. Lakeville is inside the seven-county Minneapolis- Saint Paul metro area, so the Metro Area Sales and Use Tax applies here, unlike Rochester (Olmsted County, outside the metro).
