Stove & insert installation: is a credential required in Mississippi?

#stove-installNONE

Credential: Nothing for a direct-to-homeowner install below $10,000 (MSBOC residential remodeling threshold, per Pass 1) — with no state plumbing/HVAC/mechanical license, the NG-side vacuum extends to solid fuel; EDGES: (1) installs >= $10,000 (rare) = MSBOC residential remodeler license; (2) the 2022 any-dollar SUBCONTRACTOR rule (§ 73-59-3(1)(d), per Pass 1) reaches 'mechanical' and 'HVAC' residential subs at any price — whether a stove-installing sub is doing 'mechanical work' is undefined (gray, flagged); CODE: opt-out state — Miss. Code § 17-2-4 requires non-opted-out counties/municipalities to adopt one of the last three IRC editions; opted-out swaths (roughly a third of municipalities, half of counties as of 2015) have no code and no permits at all (MID keeps the adoption list)
Issuing body: MS State Board of Contractors (>= $10k); local permits where codes adopted
Statute: Miss. Code § 73-59-3 (per Pass 1); Miss. Code § 17-2-4
Dollar threshold: $10,000 (residential remodeling)
Exam: y (MSBOC exams, at threshold)
Local overlay: y — Jackson locally registered trade professionals; opt-out map decides everything

Chimney flashing: is a credential required in Mississippi?

#chimney-flashingLICENSE

Credential: MSBOC residential license with ROOFING named at the $10,000 threshold — residential roofing (like remodeling) requires the MSBOC residential license >$10,000 (per Pass 1, msboc.us), i.e., Mississippi names roofing in its threshold structure but the floor is high enough that most standalone flashing/leak repairs are unregulated; commercial >$50,000 with roofing classification; the 2022 any-dollar residential-sub rule does NOT list roofing (electrical/plumbing/mechanical/HVAC only — per Pass 1), so a flashing sub keeps the $10k floor
Issuing body: MS State Board of Contractors
Statute: Miss. Code § 73-59-1 et seq. (residential roofing >$10,000, per Pass 1/MSBOC)
Dollar threshold: $10,000 (residential); $50,000 (commercial)
Exam: y (MSBOC exams, at threshold)
Local overlay: y — Jackson local registration

Gas fireplace service: is a credential required in Mississippi?

#gas-fireplace-serviceLICENSE (LP; MSBOC AS SUBCONTRACTOR) / NONE (NG DIRECT-TO-HOMEOWNER <$10K)

Credential: NG: NO statewide plumbing/HVAC/gas-fitter license exists — direct-to-homeowner NG gas-fireplace/gas-log/appliance work under the $10,000 remodeler threshold needs no state credential (local permits only, e.g., Jackson trade permits); BUT since 7/1/2022 any SUBCONTRACTOR of any tier performing electrical, plumbing, mechanical, or HVAC work on ANY residential construction or improvement project must hold an MSBOC license 'no matter the dollar amount' (§ 73-59-3(1)(d)) — the prime-vs-sub distinction decides licensure; LP: fully regulated at any dollar amount by the Liquefied Compressed Gas Division (MS Insurance Dept./State Fire Marshal) — CLASS 7 permit = sell/install/alter/change/repair LC-gas APPLIANCES only (piping + appliances downstream of tank outlet valve) = the gas-log class; certified qualified training required (Classes 3,7,8,9,10); LP installations must pass LC-Gas inspector approval before containers are filled (§ 75-57-47); MISMATCH: LP side licensed+insured from $0 while the NG side mirrors the chimney vacuum. FLAG: MS GC regime researched in this batch (no rights file yet) — MSBOC commercial >$50k, residential new >$50k, remodeling/roofing >$10k
Issuing body: MS State Board of Contractors (MSBOC — trade classifications); MS Insurance Dept. / State Fire Marshal, Liquefied Compressed Gas Division (LP)
Statute: Miss. Code § 73-59-3(1)(d) (2022 subcontractor rule); § 73-59-1 et seq., § 31-3-1 et seq. (MSBOC); Miss. Code Title 75 ch. 57 — §§ 75-57-47, 75-57-109 (LC-gas permits/insurance/training authority)
Dollar threshold: $10,000 residential remodeling / $50,000 new+commercial (MSBOC); $0 for residential E/P/M/HVAC SUBS since 2022; $0 for LP permits
Exam: y (MSBOC Law & Business + trade exams; LP = certified training, exam UNVERIFIED)

Gas log installation: is a credential required in Mississippi?

#gas-log-installLICENSE

Issuing body: MS Insurance Dept. / State Fire Marshal, Liquefied Compressed Gas Division
Statute: Miss. Code § 75-57-109 (permit authority); MID permit-class instructions (Classes 1–10)

What insurance does Mississippi require of contractors?

#insurance

Regime: license (MSBOC: commercial >$50k, residential new >$50k, remodeling >$10k, residential E/P/M/HVAC subs at ANY amount since 7/1/2022; LC-gas permits $0) — FLAG: GC regime researched this batch, no rights file yet
Liability minimum: MSBOC RESIDENTIAL license: GL proof REQUIRED but with NO minimum amount, and MSBOC must be LISTED ON THE POLICY to receive cancellation notification = state-verified-without-a-floor (unique structure — 'insured' is checkable but means an unknown amount); MSBOC COMMERCIAL: COI showing $300,000/occurrence + $600,000 aggregate; LC-GAS permits (MID instructions): Classes 1–6 $1,000,000/$1,000,000 public liability AND $1,000,000/$1,000,000 products (+ auto $500k/$1M/$1M for placarded vehicles); Classes 7–10 (incl. Class 7 appliance installers) $100,000/$300,000 public + $100,000/$300,000 products — ACORD COI naming the MID LC Gas Division at application AND every policy renewal = STATE-VERIFIED
Bond: NONE for MSBOC licensure (application materials list fee/exam/COI/financials — no bond; medium-high); LC-Gas Board is AUTHORIZED to set bonding (§ 75-57-109) but the current application requires insurance, not a bond; bid/performance bonds are per-project public-work instruments only
Guaranty fund: NONE — MSBOC FAQ states its complaint process 'does not guarantee restitution' and complainants 'should pursue the matter through the court system'; no fund in Title 73 ch. 59 or Title 31 ch. 3
Workers' comp threshold: 5+ workmen regularly in service (§ 71-3-5); sole props/partners and corporate officers owning >=15% of stock may exempt themselves and are EXCLUDED from the 5-count (medium); MSBOC residential licensees must submit proof of WC (if required by law) to get/renew the license (§ 73-59-3(2)(a)); prime-contractor statutory-employer rule believed yes (§ 71-3-7) — UNVERIFIED
How to verify: insurance: active MSBOC residential license = GL exists but amount unknown (badge wording: 'insurance on file with the state, amount not state-set'); commercial license = $300k/$600k; LP Class 7 = $100k/$300k state-verified; license lookup msboc.us (AUTOMATED); WC: MWCC Proof of Coverage Inquiry (mwcc.ms.gov)

Before anyone goes on your roof

What should you ask a chimney company in Mississippi?

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.
