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