North Dakota: some chimney work needs a state license. Here's what that means.

North Dakota is a cold-belt outlier that partly BREAKS the master correlation. It has a genuine statewide contractor license — but the "license" is a dollar-threshold insurance-and-paperwork credential — no exam, no bond, and on the other axis its seller disclosure is comparatively weak: broker-triggered, opt-outable in the offer, and without a named "chimney" line. So ND lands as a state with a real (if shallow) credential AND a soft disclosure — the same "strong-license / weak-disclosure" pairing the correlation predicts, which is why I read it as CONFIRMING rather than breaking. The oddity worth the page: the $4,000 gate means a chimney sweep or small repair is completely unlicensed here, while a rebuild is licensed — the licensing line runs straight through the trade.

North Dakota is the rare cold-belt state with a statewide contractor license — but it is a registration keyed to project dollars, not a trade-competency exam. Under N.D.C.C. § 43-07-02, a person may not act as a contractor "when the cost, value, or price per job exceeds the sum of four thousand dollars" without a contractor's license issued by the Secretary of State (STATE LAW); unlicensed contracting is a class A misdemeanor (§ 43-07-02). The license comes in four classes by maximum single-project value (§ 43-07-07): Class D (up to $100,000), Class C (up to $300,000), Class B (up to $500,000), Class A (no limit) — chimney rebuild, reline, or a solid-fuel appliance install over $4,000 falls squarely inside this. To get it, an applicant files (§ 43-07-04) an application under oath with a statement of experience and qualifications, a certificate of liability insurance, and a Workforce Safety & Insurance coverage statement. There is no surety bond — the former contractor's-bond section, § 43-07-11, was repealed by S.L. 1995, ch. 397, § 9 — and no examination: the word does not appear anywhere in ch. 43-07, and the Secretary of State's contractor page lists no exam or bond. Application fees run $100 (Class D) to $450 (Class A). Renewed annually on or before March 1 (§ 43-07-10). Public lookup: firststop.sos.nd.gov/search/contractor. A routine chimney sweep of $4,000 or less needs no state license at all — sweeping and small repair fall below the money-gate; only larger repair/rebuild work triggers it.

Wide, and unusually explicit here. The ND license attests that you carry liability insurance and workers'-comp coverage and filed a sworn experience statement — not that you can diagnose a flue. Chapter 43-07 contains no competency exam and no bond requirement (verified on the ndlegis statute text, Sep 2026). The license is a dollar-class credential, so individual certs (NCSG CCP/CCR; CSIA CCS, C-DET) remain the only real competence signal, and any job of $4,000 or less is entirely uncredentialed.

North Dakota's seller disclosure lives in N.D.C.C. § 47-10-02.1 but is narrower than most: the mandatory-form duty is triggered when a real estate broker/salesperson represents or assists a party to the sale of a 1–4-unit residential dwelling — a true FSBO with no agent can fall outside the form requirement (STATE LAW). The seller must disclose known material defects across structural, mechanical, heating, and environmental systems on an actual-knowledge, good-faith basis; fireplace/heating condition is captured in the mechanical/heating items, but "chimney" is not called out as its own named line on the standard ND Realtors form (confirm the exact wording before publish). Disclosure is also before final acceptance and "except as otherwise provided in the offer to purchase" — so it can be modified by agreement. No inspection is mandated at transfer; NFPA 211 Level 2 stays a NATIONAL STANDARD.

Two instruments. (1) The Unlawful Sales or Advertising Practices Act — N.D.C.C. ch. 51-15 — bars any "deceptive act or practice, fraud, false pretense, false promise, or misrepresentation" in a sale; enforced by the Attorney General's Consumer Protection Division, with a private right of action under § 51-15-09: if the defendant acted knowingly, the court may award up to three times actual damages and must award costs and actual reasonable attorney's fees; the AG may also seek a civil penalty of up to $5,000 per violation (§ 51-15-11, which also covers ch. 51-18 violations). (2) Home-solicitation sales — N.D.C.C. ch. 51-18 — give a 3-business-day right to cancel a door-to-door sale, and notably 15 business days for buyers 65 or older on purchases over $50, the exact fact pattern of a chimney door-knock scare-sale. Complaints: attorneygeneral.nd.gov.

The AG's Consumer Protection Division pursues home-repair and door-to-door abuses, and the ch. 51-18 elder 15-day window signals ND's specific concern with senior-targeted door-knock sales — the textbook "we noticed your chimney" pitch. Specific ND chimney-sweep enforcement actions: NOT CONFIRMED — re-run search before publish.

The North Dakota State Building Code was updated to the 2024 IBC, IRC, IMC and IFGC (plus 2024 IECC and IEBC), adopted Sept. 11, 2025 and effective Jan 1, 2026 (NATIONAL STANDARD via state adoption; replaces the 2023 code based on the 2021 I-codes). Local adoption is optional, but a jurisdiction that elects to enforce a building code must adopt the State Building Code (it may amend it). IRC Chapter 10 governs chimneys and fireplaces. Chimney relines, rebuilds, crowns, and solid-fuel appliance installs are generally permit work where a building department exists. The catch is reach: many rural ND counties have no local code enforcement, so a permit may simply not exist there — municipalities enforce and may amend the state code locally (LOCAL). Fargo, Bismarck, and Grand Forks run active building departments; unincorporated areas often do not.

No statewide burn-ban or wood-stove emission regime. Very high wood/pellet heat in a severe-cold plains climate, but no ND-specific stove rule — not a material content section.

North Dakota's CO-alarm requirement is code-based, not a freestanding statute — it flows from the adopted IRC (2024 edition from Jan 1, 2026) and the State Fire Marshal rule N.D.A.C. 24.1-06-01-40, which requires CO alarms in dwelling units with fuel-fired appliances or an attached garage — outside each sleeping area, on every habitable level, and in any bedroom containing a fuel-fired appliance, interconnected where more than one is required (STATE RULE + NATIONAL STANDARD via code adoption). There is no statewide mandatory pre-sale CO certificate. A permitted chimney or stove job is the natural moment to verify alarms.
