No. Standard homeowners policies exclude flood, which in insurance means external water rising and affecting two or more acres or two or more properties. It is covered separately through the National Flood Insurance Program or a private flood policy, with a thirty day waiting period. Water escaping from a pipe inside your house is a different peril and is generally covered. Building limit $250,000 Contents limit $100,000 Waiting period 30 days ## The short version - Flood is excluded from standard homeowners policies. This is near-universal, not carrier-specific. - NFIP covers building up to $250,000 and contents up to $100,000, bought separately. - There is a thirty day waiting period, with four narrow exceptions. - A burst pipe is not flood, and is generally covered under your existing policy. ## The definition, in full # Link to this section Most summaries drop the first clause, and the first clause is the part that decides cases: A general and temporary condition of partial or complete inundation of two or more acres of normally dry land area or of two or more properties (at least one of which is your property) from: overflow of inland or tidal waters; unusual and rapid accumulation or runoff of surface waters from any source; mudflow; or collapse or subsidence of land along the shore of a lake or similar body of water. Read that first line twice. A flood has to affect two or more acres or two or more properties. Water that entered only your house, from a source inside it, cannot meet the definition regardless of volume. ## If it is not flood, what is it? # Link to this section Once external water is ruled out, the question becomes what the water is , and that is a category question rather than a coverage one. Category 1 is clean supply water — a burst line, a water heater feed. Category 2 is significantly contaminated, such as appliance discharge. Category 3 is grossly contaminated: sewage, or rising external water, which is the overlap point where a flood loss and a biohazard loss are the same event. That matters because the category decides whether porous material is dried in place or removed, and it degrades with time . Floodwater is Category 3 from the moment it arrives, which is why flood losses so often involve tear-out rather than drying. ## What NFIP costs you in limits and time # Link to this section Building coverage up to $250,000 Contents coverage up to $100,000 , bought separately Waiting period 30 days from purchase If your home would cost more than $250,000 to rebuild , excess flood coverage is a separate private product. Contents are not automatic — a building-only policy leaves everything inside uncovered. ## The four exceptions to the waiting period # Link to this section These are the only ways to have coverage sooner than thirty days: - Buying while making, increasing, extending or renewing a mortgage — no wait. - Changing coverage at policy renewal — no wait. - Property newly designated in a high-risk flood zone, bought within 12 months of the map update — one day. - Flooding caused or worsened by wildfire on federal land, bought within 60 days of containment — one day. Outside those, buying as a storm approaches does not work. That is the entire purpose of the waiting period. ## What this means for your claim The practical consequence is that the answer depends entirely on where the water came from , and that question gets settled in the first phone call. Water that entered from outside and rose is flood, and your homeowners policy will not respond. Water that escaped from a system inside the building is not flood, and generally will. Rain that came through an opening the storm itself created is a third case, usually handled as wind-driven rain under the homeowners policy. Describe what happened precisely and let the adjuster classify it. Reaching for the word "flood" to mean "a lot of water" is how internal losses get evaluated under an exclusion that never applied to them. This depends on your state Insurance regulation, assignment-of-benefits rules, mold and biohazard requirements, and licensing are all set by state. This page reflects state department of insurance guidance as of 2026-08-22. Verify with your state department of insurance before you rely on it. ## Common mistakes - Assuming a homeowners policy covers flood because it covers water damage. They are different perils with different policies. - Buying flood coverage as a storm approaches. The thirty day waiting period exists precisely to prevent that. - Assuming NFIP treats a basement like the rest of the house. It does not — coverage below the lowest elevated floor is narrower. - Forgetting that NFIP contents coverage is bought separately from building coverage. ## Common follow-up questions ### Is a sewage backup a flood? No. A backup comes from the drainage system, not from external water rising, so it does not meet the NFIP definition. It is usually covered by a separate sewer and drain backup endorsement, which is frequently not included by default. ### Does NFIP cover my basement? Only narrowly. NFIP treats basements and areas below the lowest elevated floor differently from the rest of the dwelling, with limited coverage for contents and finishes. Check the current program terms before assuming. ## Related questions - The first hour after any loss - Water categories and what must be removed - Mold, the drying window, and testing - What your policy actually covers - Mold coverage is capped - What to photograph and log ## Sources Every source cited on this page - T2 ANSI/IICRC S500 Standard for Professional Water Damage Restoration — IICRC (accessed 2026-08-22) - T1 A Brief Guide to Mold, Moisture and Your Home — US EPA (accessed 2026-08-22) - T1 Mold Cleanup in Your Home — US EPA (accessed 2026-08-22) - T1 About Mold and Health — CDC (accessed 2026-08-22) - T1 Policy Terms and Coverage — FEMA / NFIP (accessed 2026-08-22) Written by: PLACEHOLDER — Claims Reviewer Reviewed by: PLACEHOLDER — Claims Reviewer Last reviewed: 2026-08-22 ## Also asked as Is water damage covered by homeowners insurance? · What water damage is covered by homeowners insurance? · Is water heater damage covered by homeowners insurance?
