Private flood, read against the NFIP.
Private flood policies are written by insurance companies rather than the National Flood Insurance Program. Some carry higher limits or extras the NFIP doesn't; some are narrower. I compare each one with the federal policy before you switch.
Quick answer Private flood policies are written by insurance companies on their own forms rather than by the NFIP, whose standard policy terms are set by FEMA; some private policies carry higher limits or extras, and some are narrower.
- The NFIP's standard policy covers up to $250,000 for a home's structure and $100,000 for its contents, on terms set by FEMA.
- The NAIC notes private flood insurers tend to offer higher limits and optional coverages, and some don't require an elevation certificate.
- Some private flood policies are narrower than the NFIP, and a private insurer can cancel or non-renew with notice.
- Federal banking rules require federally supervised lenders to accept a private flood policy that meets the federal definition, which means coverage at least as broad as the NFIP's.
- Private flood is written outside the NFIP, so it can still be placed when FEMA can't sell new NFIP policies during a lapse in authorization.

Same peril, a different contract
The NFIP's standard policy is the benchmark: up to $250,000 for a home's structure and $100,000 for its contents, on terms set by FEMA. The program also depends on Congress, and if its authorization lapses, FEMA would stop selling and renewing policies. Private insurers write their own forms, and the NAIC notes they tend to offer higher limits and optional coverages, and that some don't require an elevation certificate.
Lenders were the old obstacle. The 2012 Biggert-Waters Act affirmed that lenders may accept private flood insurance, and federal banking rules now require them to accept a private policy that meets the federal definition, which means coverage at least as broad as the NFIP's. A policy that falls short of that can still be accepted at the lender's discretion. I check where a private quote stands before your closing or renewal, not after the lender's letter arrives.
- NFIP limitsUp to $250,000 on a home's structure and $100,000 on contents; up to $500,000 each for commercial buildings.
- Private limitsSet by each insurance company, and the NAIC says they tend to run higher, with optional coverages.
- Lender acceptanceRequired for policies meeting the federal definition; discretionary for others that protect the loan.
- NFIP authorizationCongress must keep reauthorizing the program; during a lapse FEMA would stop selling and renewing policies.
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.
- Property: address, building type and year built.
- Flood zone: from your lender's determination or FEMA's map.
- Current NFIP policy: declarations page with limits, deductible and renewal date.
- Elevation certificate: if you have one; some private insurers don't ask for it.
- Lender: the flood requirement letter and the mortgagee details.
- Values: rebuild cost of the building and value of the contents.
Before you leave the NFIP, know the way back
Leaving the NFIP for a private policy can be hard to undo if your NFIP policy carries a reduced rate that depends on continuous coverage. Before I move anyone, I check what they would give up if they ever came back.
The statute is short. Under 42 U.S.C. 4014(g)(1), FEMA may not offer rates below the risk premium rates estimated under 4014(a)(1) for any NFIP policy that has lapsed in coverage, unless the policyholder let it lapse because the property was no longer required to carry flood insurance. Time spent on a private policy is not listed as an exception.
FEMA describes the effect the same way. In Proposal 17, one of 17 NFIP reform proposals the Department of Homeland Security sent to the 118th Congress in April 2023, FEMA wrote that policyholders must maintain continuous NFIP coverage to keep certain reduced premiums, and that someone who moves to a private policy may not be eligible to regain those reduced premiums on returning to the NFIP. FEMA proposed adding a subsection (n) to 42 U.S.C. 4015 that would count time continuously covered by private flood insurance as continuous coverage. That is a proposal, not law: 4014(g)(1) still lists only the one exception, and the current text of 4015 contains no such provision.
What I look at before you switch
- Your NFIP declarations page. I confirm with the NFIP insurer whether any reduced rate on the policy depends on continuous coverage.
- Why you might return. If the private policy ends for any reason, your fallback may be a new NFIP policy without the reduced rate you had.
- Timing. Keep the NFIP policy in force until the private policy's effective date is confirmed in writing, so there is no gap for you or the lender.
None of this rules private flood out. It means the comparison has to cover more than this year's quote. Section 4014(g)(1) applies to any policy under the program, so the same check applies to buildings on commercial flood insurance.
When the lender buys flood for you
When you change carriers, the servicer has to see the new policy. If the lender or servicer finds the building is not covered, or is covered for less than the required amount, 42 U.S.C. 4012a(e) and the FDIC's rule for the institutions it supervises, 12 CFR 339.7(a), require it to notify you that you should obtain flood insurance at your own expense. If you don't within 45 days after that notice, the lender or servicer must buy it on your behalf and may charge you the premiums and fees, including for coverage starting on the date your coverage lapsed or fell short.
- A declarations page is enough. Under 339.7(b)(2), the lender or servicer must accept a declarations page that shows the existing policy number and the identity of, and contact information for, the insurer or agent.
- Overlap is refunded. Under 339.7(b)(1), within 30 days of receiving that confirmation, the lender or servicer must notify the insurer to terminate the force-placed policy and refund the premiums you paid for it, plus related fees, for any period when both policies were in effect.
Escrow follows the flood requirement
For residential loans made, increased, extended or renewed on or after January 1, 2016, 12 CFR 339.5(a) requires the lender or servicer to escrow all premiums and fees for the required flood insurance. The exceptions in 339.5(a)(2) are loans mainly for business, commercial or agricultural purposes; subordinate liens where the senior lien already has qualifying coverage; coverage paid by a condo, co-op or HOA as a common expense; home equity lines of credit; nonperforming loans 90 or more days past due; and loans with a term of 12 months or less. Section 339.5(c) also exempts certain smaller institutions. Under 339.5(a)(4), the servicer pays the insurer from escrow after it receives notice that premiums are due, so I send the new declarations page and billing to the mortgagee on your loan, not just to you.
Private flood insurance, answered
Is private flood insurance better than the NFIP?
Not automatically. Some private policies offer higher limits and optional coverages; others are narrower, and a private insurer can cancel or non-renew with notice. I lay the private form beside the NFIP's standard policy before you choose.
Will my mortgage lender accept a private flood policy?
Lenders supervised by the federal banking agencies must accept a private policy that meets the federal definition of private flood insurance and carries the required amount. If the policy or an endorsement says 'This policy meets the definition of private flood insurance contained in 42 U.S.C. 4012a(b)(7) and the corresponding regulation,' the lender can rely on it without further review.
What counts as 'private flood insurance' under the federal rule?
A policy from an insurer licensed or admitted in the property's state (or a surplus lines insurer, for certain blanket commercial policies) that covers at least as broadly as the NFIP's standard policy, including deductibles, exclusions and conditions. It must also give you and the lender 45 days' written notice before cancellation or non-renewal, tell you NFIP coverage is available, include a mortgage interest clause, and allow at least one year after a written claim denial to file suit.
Can a lender accept a policy that doesn't meet that definition?
Yes, at its discretion, if the policy provides the required amount, comes from an insurer licensed in the state (or a recognized surplus lines insurer for nonresidential commercial property), names both you and the lender as loss payees, and the lender documents in writing that it protects the loan.
How much flood coverage does my lender require?
At least the lesser of the outstanding loan balance or the most the NFIP makes available for that type of building. That's a floor for the loan, not a measure of what it costs to rebuild.
What happens if the NFIP's authorization lapses?
FEMA would stop selling and renewing NFIP policies but could still pay valid claims with available funds. FEMA's reauthorization page shows the current deadline.
Will a lender accept a mutual aid plan instead of flood insurance?
Only in limited cases. Under 12 CFR 339.3(c)(4), an FDIC-supervised lender may accept a mutual aid society plan if the FDIC has determined such plans qualify as flood insurance, the plan provides the required amount, it covers both borrower and lender as loss payees, and the lender documents in writing that it sufficiently protects the loan.
Do you offer private 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.
