Stove & insert installation: is a credential required in Idaho?
#stove-installLICENSE- Credential
- SOLID FUEL IS INSIDE THE HVAC ACT — the task question ('does the hearth-named scope cover solid fuel or gas only?') resolves SOLID FUEL YES: § 54-5003(3) defines the licensed HVAC contractor as one who installs warm air heating systems 'complete with warm air appliances including, but not limited to, boilers, pool heaters, space heaters, DECORATIVE GAS AND SOLID FUEL-BURNING APPLIANCES', and the LP-only specialty limited heating class EXPRESSLY EXCLUDES 'solid fuel and electric fueled systems' (§ 54-5003(10)) — a wood/pellet stove or insert install is licensed HVAC work (contractor certificate = exam + $2,000 compliance bond; journeyman layer under it); the Specialty Journeyman 'hearth appliances' lane (IDAPA 24.39.70.100.04.a) is NOT fuel-limited in the current rule text and reads on wood/pellet hearth appliances too (its 60-hr education alternative is fuel-gas-code coursework — gas-oriented but not gas-exclusive; board guidance UNVERIFIED); PERMIT NAMED: the statewide HVAC permit fee schedule lists 'free-standing solid-fuel stove' BY NAME (Rule 500.02.a) and DOPL itself issues the permit where no local program exists — the permit trail reaches unincorporated Idaho; CODE: Idaho Mechanical Code (Rule 600) = 2018 IMC + 2018 IFGC + 2018 IRC Parts V-VI, so the listing/manufacturer-instruction rules ride the HVAC permit statewide independent of local building depts (building side: Idaho Residential Code 2020 ed. = 2018 IRC Parts I-III/IX); NFI: voluntary — current 3/28/2023 rule does not name NFI (Pass 1 correction); WOOD-SMOKE OVERLAY: West Silver Valley PM2.5 nonattainment area (Pinehurst/Kellogg/Smelterville/Kingston/Enaville) + Sandpoint Ord. 1258 (EPA-certified stoves REQUIRED in new construction; mandatory curtailment on yellow/red advisories) — device standards and burn bans, no installer credential

Gas fireplace service: is a credential required in Idaho?
#gas-fireplace-serviceLICENSE- Credential
- Dual-layer DOPL HVAC credential with a HEARTH-NAMED lane: HVAC contractor certificate of competency (Board exam + $2,000 compliance bond, IDAPA 24.39.70.100.03) employing certified journeymen — and the Specialty Journeyman certificate (IDAPA 24.39.70.100.04) whose permitted scope IS the hearth trade: 'install hearth appliances, and non-duct connected oil furnaces, the associated fuel gas piping, and venting dedicated exclusively thereto' (2,000 hrs specialty experience + Board exam OR 60 hrs of fuel-gas-code/piping education; earlier rule versions named the National Fireplace Institute program as approved training — the current 3/28/2023 rule text does not name NFI); HVAC permits are required statewide and the fee schedule names 'decorative gas-fired appliance' and 'factory-built gas fireplace' BY NAME (Rule 500.02.a), with DOPL itself issuing permits where no local program exists; LP SPLIT AT THE SECOND-STAGE REGULATOR: the Idaho LPG Public Safety Act governs outdoor LPG tank setting + outdoor piping through the second-stage regulator 'notwithstanding' HVAC/plumbing law (§ 54-5302(4)) via DOPL LPG Safety Board dealer/facility licenses, while indoor LP piping + the appliance connection stay HVAC; chimney/masonry work needs only the exam-free contractor registration (Title 54 ch. 52) — and § 54-5213 bans local licensing, so nowhere in Idaho is chimney competence ever tested
- Issuing body
- Idaho DOPL — HVAC Board (Title 54 ch. 50); Idaho LPG Safety Board (Title 54 ch. 53, tank-to-second-stage lane)
- Statute
- Idaho Code Title 54 ch. 50 (§§ 54-5008, 54-5009, 54-5015); IDAPA 24.39.70.100, .300, .500; Idaho Code §§ 54-5302(4), 54-5303(9)
- Dollar threshold
- none ($0 — certification + permit from the first gas appliance; contrast: general contractor registration exempt under $2,000 aggregate, § 54-5205(2)(f))
- Exam
- y (HVAC contractor + journeyman exams; specialty journeyman may substitute the 60-hr fuel-gas education for the exam; LPG dealer exam § 54-5307(4))
- Local overlay
- n — § 54-5015 gives the state exclusive HVAC jurisdiction (locals may not require additional licenses/fees) and § 54-5213 bans local contractor registration outright; local building depts handle only building-side permits

Gas log installation: is a credential required in Idaho?
#gas-log-installLICENSE- Credential
- LP lane tracked separately: a propane log-set job SPLITS at the second-stage regulator — outdoor tank setting + outdoor piping through the second-stage regulator is LPG-DEALER-licensed work (§ 54-5302(4) makes the LPG chapter govern that zone 'notwithstanding any other provisions of law pertaining to the installation of plumbing and heating, ventilation, and air conditioning systems'; 'LPG dealer practice' includes 'installation or maintenance of systems, equipment, pipes or containers for the use or storage of LPG', § 54-5303(9); unlicensed LPG practice = misdemeanor, $1,000/6 months, § 54-5316; dealer license = board-approved training + experience + exam, § 54-5307), while the indoor piping, appliance connection and venting stay with the DOPL HVAC credential incl. the hearth-scoped Specialty Journeyman; LPG FACILITY licenses (fixed selling/filling locations) require a $1,000,000 single-limit GL certificate filed with the board (§ 54-5308(1)(j)) — the only state-filed $1M instrument in Idaho contracting; NG log sets ride the HVAC lane alone
- Issuing body
- Idaho LPG Safety Board (DOPL) + DOPL HVAC Board
- Statute
- Idaho Code §§ 54-5302(4), 54-5303(8)-(9), 54-5304, 54-5307, 54-5308, 54-5316; IDAPA 24.39.70.100.04

What insurance does Idaho require of contractors?
#insurance- Regime
- registration (Contractor Registration Act, Title 54 ch. 52 — no exam, no bond) + exam-based trade licenses (HVAC/plumbing/electrical); chimney work = registration-only
- Liability minimum
- $300,000 single-limit GL required of EVERY registered contractor — proof of the policy submitted with the application made under oath (Idaho Code § 54-5210(1)) — the registration IS an insurance attestation-plus-document regime: DOPL sees evidence at registration/renewal ($150/yr cap) but no continuous-monitoring/lapse-suspension mechanism was found (medium — treat as document-verified at renewal, request carrier-direct COI for currency); LPG FACILITY licenses: $1,000,000 single-limit GL certificate FILED with the LPG Safety Board (§ 54-5308(1)(j)) = state-held; no GL attaches to the HVAC license itself
- Bond
- NO registration bond and no consumer-restitution surety at any tier; the HVAC contractor certificate requires a $2,000 COMPLIANCE bond effective for the certificate period (IDAPA 24.39.70.100.03) — a code-compliance instrument, not consumer money; no LPG dealer bond found (absence, medium)
- Guaranty fund
- NONE — no recovery/guaranty fund in Title 54 ch. 52 (registration), ch. 50 (HVAC) or ch. 53 (LPG) (absence verified from chapter texts); the $300k GL policy + ICPA remedies (§ 48-608 incl. elderly $15k/treble) are the consumer instruments; unregistered contractors can't sue and waive lien rights (§§ 54-5217(2), 54-5208)
- Workers' comp threshold
- 1 employee (Idaho Code § 72-301); sole proprietor exempt for self (§ 72-212 — 'owner of a sole proprietorship' excluded); family-member employees of sole props auto-exempt while residing with the owner (§ 72-212(4)), non-household family members file the IC53 election with the Industrial Commission (§ 72-212(5)); registration application requires WC proof OR a written exemption statement (§ 54-5210) — registration implies WC-or-statement on file
- How to verify
- DOPL Verify-a-License (dopl.idaho.gov) covers contractor registration + HVAC/plumbing/electrical + LPG credentials in ONE portal = AUTOMATED (deep lookup URL still unpinned per rights file); GL = registration implies a $300k policy existed at last renewal — carrier-direct COI for currency = DESK; WC = Idaho Industrial Commission Employer Compliance Division (public coverage lookup UNVERIFIED) + IC53 exemption paper = DESK

Before anyone goes on your roof
What should you ask a chimney company in Idaho?
- Is your company a member of the National Chimney Sweep Guild (NCSG)?
- Does the technician coming to my home hold an individual NCSG certification, and which one?
- Does the technician hold a National Fireplace Institute (NFI) certification — and for which fuel: wood, gas, or pellet?
- What other certifications does the technician hold (for example, CSIA), and can I check them on the issuer's own roster?
- What state or local license or registration covers this work here, and what is the number?
- Will you send a certificate of insurance, dated and naming your company, before work starts?
- Which NFPA 211 inspection level — Level 1, 2, or 3 — are you performing, and why that level?
- Will you show me what you found — photos or video of the flue — in writing?
We take no fee from any certification body, guild, or contractor, and are not paid to mention anyone named.
