Flood insurance, NFIP or private.
Homeowners policies exclude flood. I compare National Flood Insurance Program policies with private flood markets, including excess coverage for homes worth more than NFIP limits.
Quick answer You generally need flood insurance if your home is in a high-risk flood zone with a federally backed loan; elsewhere it isn't usually required, but homeowners policies exclude flood and flooding happens outside high-risk zones too.
- Standard homeowners, condo and renters policies exclude flood damage; flood coverage comes from the NFIP or from private flood insurers.
- Outside high-risk flood zones, flood insurance isn't usually required, but flooding happens there too and premiums there are often lower.
- Flooding can happen outside mapped high-risk zones, including from heavy rain and mudflow after wildfires.
- NFIP flood policies generally take effect 30 days after purchase, with some exceptions such as a loan closing.
- Beyond National Flood Insurance Program (NFIP) policies, private flood markets include excess coverage for homes worth more than NFIP limits.

Flood isn’t covered by your home policy
Standard homeowners, condo and renters policies exclude flood damage. Coverage comes from the NFIP or from private flood insurers.
Flood can happen outside mapped high-risk zones, including from heavy rain and mudflow after wildfires.
- NFIP limitsUp to $250,000 for a residential building and $100,000 for contents.
- Waiting periodNFIP policies generally take effect 30 days after purchase, with some exceptions such as a loan closing.
- Private floodCan offer higher limits, additional living expenses and different waiting periods, depending on the insurer.
- Excess floodCoverage above NFIP limits for higher-value homes.
What underwriters will ask
Having these ready means I can go to market on the first call. The quote form asks for the same things, and anything you don’t know yet can wait.
- The property: address and building type.
- Flood zone: from your lender or FEMA’s map, if you know it.
- Elevation certificate: if you have one.
- Foundation: slab, crawlspace, basement or raised.
- Values: building and contents.
- Deadline: loan closing or lender requirement date.
Excess flood: coverage above the NFIP caps
The NFIP's ceiling is set by federal statute, not by the insurance company. Under 42 U.S.C. 4013, the residential caps on this page apply to a building designed for one to four families. A nonresidential building, including a church, can carry up to $500,000 on the building, up to $500,000 on the owner's contents and up to $500,000 per unit on a tenant's contents. Damage beyond the limit you carry isn't paid by the NFIP policy.
Excess flood is a private policy written to respond after the NFIP limit is used up. I check how the two fit together:
- Which policy pays first. The NFIP Dwelling Form's Other Insurance clause says that when another flood policy states it is excess insurance, the NFIP policy is primary. Without that wording, the NFIP policy generally pays only its proportional share of the loss.
- No gap between layers. I confirm the excess quote starts exactly where the NFIP building limit you actually carry ends.
- How the NFIP layer settles. The Dwelling Form pays replacement cost only on a single-family principal residence insured to at least 80 percent of its full replacement cost, or to the NFIP maximum. Other dwellings settle at actual cash value, or a proportional amount if underinsured. Excess terms vary by insurer, so I read them.
- What the lender requires. The federal purchase requirement is the lesser of the outstanding loan balance or the maximum coverage available under the Act for that type of property. Anything above that is up to you and your loan documents.

Private flood and your lender: the acceptance rule
Since July 1, 2019, federally regulated lenders have had to accept private flood policies that meet the federal definition. The OCC, Federal Reserve, FDIC, Farm Credit Administration and NCUA issued the rule jointly; the OCC's version is 12 CFR Part 22 and the FDIC's is 12 CFR Part 339. It applies to "designated loans": loans secured by a building or mobile home in a special flood hazard area where NFIP coverage is available.
A lender must accept a private policy that carries the required amount and meets the definition, which includes:
- An insurer licensed, admitted or otherwise approved by the insurance regulator of the state where the property sits, or, for blanket-type policies on nonresidential commercial property, a surplus lines insurer that state recognizes or does not disapprove.
- Coverage at least as broad as the NFIP standard policy for the same type of property, counting deductibles, exclusions and conditions.
- 45 days' written notice to you and the lender before cancellation or non-renewal, and cancellation terms as restrictive as the NFIP policy's.
- Information about NFIP availability, a mortgage interest clause, and a one-year deadline to sue after a written claim denial.
If the policy or an endorsement states, "This policy meets the definition of private flood insurance contained in 42 U.S.C. 4012a(b)(7) and the corresponding regulation," the lender may accept it without further review. A lender may not reject a qualifying policy solely because that sentence is missing. Lenders may also accept, at their discretion, some policies outside the definition if they document in writing that the loan is sufficiently protected. A declarations page alone may not show enough, so I send lenders the full policy. More: private flood insurance.
Flood insurance, answered
Is flood covered by homeowners insurance?
No. Flood damage is excluded from standard homeowners, condo and renters policies.
How much coverage does the NFIP offer?
Up to $250,000 for a residential building and $100,000 for contents.
How soon does flood insurance start?
NFIP policies generally have a 30-day waiting period, with exceptions such as coverage required for a loan. Private flood waiting periods vary.
Do I need flood insurance outside a high-risk zone?
It isn’t usually required, but flooding happens outside high-risk zones too, and premiums there are often lower.
Does flood insurance pay lost rent on a rental property?
Not under the NFIP Dwelling Form, which excludes loss of revenue, loss of use and additional living expenses. Rent-loss protection has to come from a separate private policy where one offers it.
Does a tenant need their own flood insurance?
A landlord's NFIP contents coverage applies to property owned by the named insured or household family members, not tenants. FEMA issues the Dwelling Form to residential renters, so a tenant can buy their own contents policy.
Do you offer flood insurance outside California?
Yes. Clients across the country send the same quote form. Sam Alishahi is licensed in all 50 states and Washington, DC and places policies there directly. The shopping across carriers works the same way. Rules, minimums and markets differ by state — see insurance requirements by state or high-value home insurance by state.
