    {
      "category": "verification",
      "q": "How do I verify a contractor's license in Boston?",
      "a": "Contractors in Boston are regulated by Massachusetts Construction Supervisor License (CSL). Use the official lookup at https://www.mass.gov/construction-supervisor-license with the license number. Confirm the status reads \"Active\" (not Expired, Suspended, or Revoked), the expiration date is in the future, and there are no open disciplinary actions. AskBaily's free multi-jurisdiction tool at /tools/license-lookup deep-links you to the right regulator in one click."
    },
    {
      "category": "insurance",
      "q": "What are the minimum insurance requirements for Boston contractors?",
      "a": "Boston contractors working on residential renovation must carry general liability insurance and workers' compensation for any employees. Minimums vary by license class — the required class here is: Unrestricted CSL for buildings over 35,000 cubic feet; Restricted CSL for 1-2 family residential. Ask for a Certificate of Insurance (COI) listing you as additional insured before work starts."
    },
    {
      "category": "permits",
      "q": "How long does a renovation permit take in Boston?",
      "a": "Boston permit timelines depend on scope and jurisdiction. Simple interior remodels with no structural, electrical panel, or plumbing-fixture-count changes often go through over-the-counter or express review in 2-6 weeks. Scope touching structure, egress, seismic/wind, or historic review extends to 8-20 weeks. AskBaily's Boston cost hub at /cost/boston cites the current local median."
    },
    {
      "category": "deposits",
      "q": "What's a fair deposit for a Boston renovation?",
      "a": "Most jurisdictions cap deposits at 10% of contract value or $1,000 (whichever is less) for licensed residential work. Boston contractors who request 30%+ cash up front are signaling a fraud pattern — walk away. A proper deposit goes against scheduled progress payments tied to milestones (permit issuance, rough-in, drywall, completion), not into the contractor's general operating account."
    },
    {
      "category": "fraud",
      "q": "What contractor-fraud red flags should Boston homeowners watch for?",
      "a": "Common Boston fraud patterns: door-to-door solicitation after a storm, wildfire, or earthquake; pressure to skip permits; refusal to put the license number in writing; demand for cash or wire-transfer deposits >20%; offer to use \"their supplier\" for materials at inflated prices; no written contract or scope document. Any one of these is immediate walk-away."
    },
    {
      "category": "costs",
      "q": "How much does a kitchen remodel cost in Boston?",
      "a": "Boston kitchen remodel costs vary by scope. Light refresh (cabinet reface, counter swap, appliance upgrade) runs toward the lower end; full gut (new layout, plumbing relocation, permit work) runs 3-5x higher. AskBaily's Boston cost hub at /cost/boston shows the current local price band by project scope. Labor in Boston trends above or below national average depending on market density and trade availability."
    },
    {
      "category": "costs",
      "q": "How much does a bathroom remodel cost in Boston?",
      "a": "Boston bathroom remodel cost depends on fixture count (single-vanity vs double), whether plumbing is relocated, and whether the scope is a primary suite. Permit fees are typically bundled into the GC's invoice. Current Boston price bands are in AskBaily's cost hub at /cost/boston. Expect premium-market Boston neighborhoods to trend 20-40% above metro median."
    },
    {
      "category": "costs",
      "q": "How much does a whole-home renovation cost in Boston?",
      "a": "Whole-home Boston renovations scale with square footage, mechanical replacement scope, and permit class. A cosmetic refresh (paint, floors, appliances, no structural) is fundamentally different from a gut renovation (down to studs, new MEP, new plan). Boston's Massachusetts Construction Supervisor License (CSL) may require specific permits for each scope component. AskBaily's Boston cost hub breaks this out by scope tier."
    },
    {
      "category": "licensing",
      "q": "Is a contractor license required in Boston?",
      "a": "Yes. Any residential renovation work in Boston above a minimum contract threshold must be performed by a contractor licensed by Massachusetts Construction Supervisor License (CSL). Unlicensed work voids most homeowner warranties, prevents inspection pass, and shifts liability to the homeowner for any injury or property damage that occurs. Check license status before signing."
    },
    {
      "category": "licensing",
      "q": "What happens if I hire an unlicensed contractor in Boston?",
      "a": "Hiring unlicensed in Boston exposes you to: (1) no statutory protection if work is defective — you can't sue under the licensing-board framework; (2) personal liability if a worker is injured on your property and there's no workers' comp; (3) failed building inspections because Boston AHJs won't certify work by an unlicensed contractor; (4) invalidated homeowners' insurance claims related to the renovation. Always verify first."
    },
    {
      "category": "regulators",
      "q": "Who regulates contractors in Boston?",
      "a": "Massachusetts Construction Supervisor License (CSL) is the primary contractor regulator for Boston. Their official site is https://www.mass.gov/construction-supervisor-license. The board enforces license requirements, investigates complaints, maintains disciplinary records, and can suspend or revoke licenses for violations. For permit-specific matters, Boston also has a municipal building department — consult your specific project address for overlay requirements."
    },
    {
      "category": "complaints",
      "q": "How do I check a Boston contractor's complaint history?",
      "a": "Massachusetts Construction Supervisor License (CSL) publishes complaint records for licensed contractors in Boston. Search the business name and the responsible licensee's name at the regulator's lookup page. One older complaint that was resolved is normal. Multiple open complaints or any suspension history is a warning sign — ask the contractor directly about them before signing."
    },
    {
      "category": "insurance",
      "q": "What's the difference between licensed, bonded, and insured in Boston?",
      "a": "In Boston: \"Licensed\" means Massachusetts Construction Supervisor License (CSL) issued a current license. \"Bonded\" means the contractor has posted a surety bond that can be claimed against if they fail to complete work or abandon the project. \"Insured\" means they carry general liability insurance covering property damage caused during work plus workers' compensation for their employees. You want all three — a contractor missing any one is a risk."
    },
    {
      "category": "cross-jurisdiction",
      "q": "Can a contractor from outside Boston work there?",
      "a": "A contractor from another jurisdiction can work in Boston only if their license is recognized (via reciprocity) or they obtain a Boston-specific license. Many out-of-area contractors partner with a locally-licensed GC who holds the prime contract and permit. If someone pitches you as an out-of-area contractor without a local licensing partnership, verify their Boston-specific credentials before signing."
    },
    {
      "category": "contract",
      "q": "What must be in writing for a Boston renovation contract?",
      "a": "A Boston renovation contract must include: scope of work with specific materials and finishes; total contract price; progress-payment schedule tied to milestones; start and substantial-completion dates; change-order process (written, priced, signed before work); warranty on workmanship; dispute-resolution mechanism; contractor license number and insurance carrier. Any verbal promise not in the contract is unenforceable."
    },
    {
      "category": "complaints",
      "q": "How do I file a complaint against a Boston contractor?",
      "a": "File a formal complaint with Massachusetts Construction Supervisor License (CSL) via https://www.mass.gov/construction-supervisor-license. Include: contract, payment records, dated photos of defective work, correspondence, and any inspection reports. The board investigates and can impose fines, require restitution, or suspend/revoke the license. For urgent safety issues (gas, structural, electrical hazards), also notify the Boston building department directly so inspectors can intervene."
    },
    {
      "category": "permits",
      "q": "What permits do I need for a Boston renovation?",
      "a": "Permit requirements in Boston depend on scope. Structural changes, electrical panel work, plumbing modifications (especially relocating fixtures), window/door modifications, roofing, HVAC replacement, and additions all require permits. Cosmetic-only work (paint, flooring, fixture swap same location) usually does not. Your contractor should pull permits in their name, not yours — never agree to \"pull it yourself\" as a cost-saving, which shifts liability to you."
    },
    {
      "category": "askbaily",
      "q": "What's AskBaily's verification process for Boston contractors?",
      "a": "At the moment we match you with a Boston contractor, AskBaily queries Massachusetts Construction Supervisor License (CSL) in real time to confirm the license is Active, not Suspended, and in good standing. We also verify current insurance coverage. If any check fails, the match does not happen. This is live verification at match time — not a one-time onboarding check that goes stale after six months. See /methodology for the full workflow."
    },
    {
      "category": "askbaily",
      "q": "Why use AskBaily instead of Angi in Boston?",
      "a": "Angi broadcasts your Boston inquiry to 3-8 contractors and charges each $30-80 as a lead fee — costs that end up in your quote. AskBaily scopes your project with AI first, then introduces ONE verified Boston contractor. No lead fees. No broadcast. Live license verification at match time (Angi relies on self-reported contractor profiles updated at signup). See /vs/angi for the full contrast."
    },
    {
      "category": "timing",
      "q": "How quickly can AskBaily match me with a Boston contractor?",
      "a": "Boston metros in AskBaily's active partner program match within 2-4 business days of scope completion for standard residential scopes. Ramping metros (where we're still recruiting the first 2-3 founding partners) may take 1-2 weeks while we qualify a verified Boston contractor with matching specialty. Urgent scopes (insurance claim, fire/flood rebuild) are routed same-day when a qualified partner is online."
