    {
      "category": "verification",
      "q": "How do I verify a contractor's license in Osaka?",
      "a": "Contractors in Osaka are regulated by MLIT 建設業許可. Use the official lookup at https://www.mlit.go.jp/sogoseisaku/1_6_hf_000039.html 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 Osaka contractors?",
      "a": "Osaka 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: 建設業許可 一般 or 特定. 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 Osaka?",
      "a": "Osaka 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 Osaka cost hub at /cost/osaka cites the current local median."
    },
    {
      "category": "deposits",
      "q": "What's a fair deposit for a Osaka renovation?",
      "a": "Most jurisdictions cap deposits at 10% of contract value or $1,000 (whichever is less) for licensed residential work. Osaka 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 Osaka homeowners watch for?",
      "a": "Common Osaka 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 Osaka?",
      "a": "Osaka 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 Osaka cost hub at /cost/osaka shows the current local price band by project scope. Labor in Osaka trends above or below national average depending on market density and trade availability."
    },
    {
      "category": "costs",
      "q": "How much does a bathroom remodel cost in Osaka?",
      "a": "Osaka 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 Osaka price bands are in AskBaily's cost hub at /cost/osaka. Expect premium-market Osaka neighborhoods to trend 20-40% above metro median."
    },
    {
      "category": "costs",
      "q": "How much does a whole-home renovation cost in Osaka?",
      "a": "Whole-home Osaka 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). Osaka's MLIT 建設業許可 may require specific permits for each scope component. AskBaily's Osaka cost hub breaks this out by scope tier."
    },
    {
      "category": "licensing",
      "q": "Is a contractor license required in Osaka?",
      "a": "Yes. Any residential renovation work in Osaka above a minimum contract threshold must be performed by a contractor licensed by MLIT 建設業許可. 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 Osaka?",
      "a": "Hiring unlicensed in Osaka 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 Osaka 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 Osaka?",
      "a": "MLIT 建設業許可 is the primary contractor regulator for Osaka. Their official site is https://www.mlit.go.jp/sogoseisaku/1_6_hf_000039.html. The board enforces license requirements, investigates complaints, maintains disciplinary records, and can suspend or revoke licenses for violations. For permit-specific matters, Osaka also has a municipal building department — consult your specific project address for overlay requirements."
    },
    {
      "category": "complaints",
      "q": "How do I check a Osaka contractor's complaint history?",
      "a": "MLIT 建設業許可 publishes complaint records for licensed contractors in Osaka. 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 Osaka?",
      "a": "In Osaka: \"Licensed\" means MLIT 建設業許可 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 Osaka work there?",
      "a": "A contractor from another jurisdiction can work in Osaka only if their license is recognized (via reciprocity) or they obtain a Osaka-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 Osaka-specific credentials before signing."
    },
    {
      "category": "contract",
      "q": "What must be in writing for a Osaka renovation contract?",
      "a": "A Osaka 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 Osaka contractor?",
      "a": "File a formal complaint with MLIT 建設業許可 via https://www.mlit.go.jp/sogoseisaku/1_6_hf_000039.html. 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 Osaka building department directly so inspectors can intervene."
    },
    {
      "category": "permits",
      "q": "What permits do I need for a Osaka renovation?",
      "a": "Permit requirements in Osaka 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 Osaka contractors?",
      "a": "At the moment we match you with a Osaka contractor, AskBaily queries MLIT 建設業許可 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 Osaka?",
      "a": "Angi broadcasts your Osaka 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 Osaka 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 Osaka contractor?",
      "a": "Osaka 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 Osaka contractor with matching specialty. Urgent scopes (insurance claim, fire/flood rebuild) are routed same-day when a qualified partner is online."
