Stove & insert installation: is a credential required in District of Columbia?
#stove-installLICENSE- Credential
- No solid-fuel trade credential (the exam-tested gasfitter lane is gas-only, per Pass 1) — the capture is the contracting + permit stack: Home Improvement Contractor BBL from $300 (the $25k bond + $50k/$100k/$10k GL stack rides along, per Pass 4; no exam) plus a DOB permit under the 2017 DC Construction Codes (2015 IRC base — DCRC ch. 10 chimneys/fireplaces carries the listing/manufacturer-instruction rules; codes in force since 5/29/2020; next-cycle adoption status UNVERIFIED); trade permits issue only to licensed/bonded master trade professionals and homeowners cannot self-pull them — WHICH master license the DOB desk demands for a solid-fuel appliance (building permit vs mechanical trade permit) is UNVERIFIED; ROWHOUSE/PARTY-WALL ANGLE (task question answered): NO codified shared-flue/party-wall chimney provision found in the DCRC — party-wall chimneys are a construction-stock fact governed by common-law party-wall doctrine + standard IRC ch. 10 rules (absence is the finding); 16 DCMR § 899 excludes licensed plumber/gasfitter work from 'home improvement' (per Pass 1) but a solid-fuel install is not gasfitter work — the HIC BBL applies

Chimney flashing: is a credential required in District of Columbia?
#chimney-flashingLICENSE- Credential
- No roofing-specific license — flashing/leak repair on a residence is 'home improvement work' captured by the HIC BBL from $300 (the $25k bond + $50k/$100k/$10k GL stack, per Pass 4; no exam — the MD-MHIC pattern one river over) or by a General Contractor/Construction Manager BBL; PERMIT LAYER: DOB 'postcard permit' covers basic non-structural residential roofing repairs (flashing-scale work) while structural repairs/full replacements need a building permit; 16 DCMR § 899's plumber/gasfitter exclusion does not reach roofing — flashing stays inside home improvement; no trade exam anywhere in the lane (the bonded-but-competence-blind DC pattern from Pass 1 extends to the roof)

- Issuing body

What insurance does District of Columbia require of contractors?
#insurance- Regime
- license
- Liability minimum
- HIC endorsement: GL + property damage insurance for the FULL license period, minimums $50,000 bodily injury per person / $100,000 aggregate per accident / $10,000 property damage per accident, cancelable only on 30 days' notice to the Director (16 DCMR § 803.1–.2); self-insurance alternative: net worth ≥ $100,000 incl. a $5,000 claims reserve + a claims-handling employee, proven by CPA certificate + affidavit (§ 803.3–.4). CORRECTION to prior belief: insurance is NOT 'in lieu of' the bond — §§ 802 and 803 are two separate stacked requirements. Trade side: NO GL minimum located for plumber/gasfitter licensees — their instrument is the $5,000 bond only. TRAP: DCMR text verified from a 2017 mirror (see UNVERIFIED)
- Bond
- HIC: $25,000 surety bond running to the District, extending to third-party recovery, term = the 2-year license period (16 DCMR § 802.1); alternative to the BOND (not insurance): deposit with the D.C. Treasurer of $25,000 cash/certified check or US-government bonds with ≥ $26,000 maturity value (§ 802.4–.5); surety NOT liable for job completion — only homeowner financial loss from violations criminally prosecutable (§ 802.3). Plumber/gasfitter: $5,000 'Plumbing and Gas Fitting Bond' per licensee — separate bonds for the contractor entity AND the designated master — payable to the District and any aggrieved person, expires March 31 of even years (DLCP bond form, citing Act of Dec. 20, 1944, 58 Stat. 819). Both bond types are FILED WITH DLCP = STATE-VERIFIED at licensure/renewal; insurance evidence also furnished to the Director = STATE-VERIFIED at issuance (continuous-coverage policing between renewals is the weak point)
- Guaranty fund
- NONE — DC has no home-improvement guaranty/recovery fund; searches return only Maryland's MHIC Guaranty Fund and CT/MA funds (absence is the finding — and a confusion risk for DC customers who know the MD fund). DC substitutes: claims on the $25k HIC bond, the § 800.1 disgorgement rule, and CPPA treble/$1,500 damages
- Workers' comp threshold
- 1+ employees — 'if an employer has one (1) or more employees, the employer is required to have workers' compensation insurance coverage' (DOES OWC FAQ); D.C. Code § 32-1501 et seq., coverage § 32-1503; even domestic workers at 240+ hrs/quarter; self-insurance only with OWC approval; sole proprietor with zero employees owes no coverage for self; corporate-officer exemption mechanics NOT located (see UNVERIFIED)
- How to verify
- WC: PUBLIC ONLINE LOOKUP EXISTS — DOES links 'Employers' Workers' Compensation Insurance Coverage Verification' to https://www.ewccv.com/cvs/ (NCCI coverage-verification portal); not request-based-only. BBL/HIC: Scout https://scout.dcra.dc.gov (also branded scout.dlcp.dc.gov). Trade licenses: https://govservices.dcra.dc.gov/oplaportal. Bonds: filed with DLCP, not independently searchable — bond status is inferred from license being active

Before anyone goes on your roof
What should you ask a chimney company in District of Columbia?
- 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.
