Flood insurance on a coastal condo: master policy, RCBAP gap and unit-owner coverage
A unit in a Special Flood Hazard Area is a designated loan whatever the occupancy: the lender measures the association’s RCBAP against your balance and insurable share, requires a unit policy for any shortfall, and the escrow exemption depends on the master policy.
The requirement follows the building, not the occupancy
When the condo building sits in a Special Flood Hazard Area of a community that participates in the National Flood Insurance Program, the lender must require flood coverage for the life of the loan, and nothing in the statute exempts a second home or a seasonal unit. Required coverage is the lesser of the outstanding principal balance, the insurable value of the building portion securing the loan, or the NFIP maximum of $250,000 for a residential building. You will see a flood determination fee on the Loan Estimate and receive notice of the flood status before closing; the determination can be challenged with an elevation certificate and a letter of map amendment when the structure is above the base flood elevation.
How the association’s policy is counted
Most coastal associations carry a Residential Condominium Building Association Policy, which insures the whole building up to the lesser of its replacement cost or $250,000 multiplied by the number of units. The lender allocates your unit’s share — typically the building’s coverage divided by the unit count — and compares it with the required amount. If the RCBAP covers the building at full replacement cost, the unit is usually satisfied with no separate policy. If the association bought less, whether to save on premiums or because the building was undervalued, the lender must require you to close the gap with an individual NFIP dwelling policy or an acceptable private policy. That gap is the classic post-contract surprise in beachfront projects, and it can cost more than the HO-6. Note that the RCBAP carries an 80% coinsurance clause: an underinsured building also pays reduced claims, which feeds special assessments after a storm.
Escrow, force-placement and premiums on a non-primary unit
The 2014 reforms require lenders to escrow flood premiums on most loans made or renewed after January 1, 2016, but a unit whose flood insurance comes from the association’s master policy and is paid through dues is exempt from that escrow; any supplemental unit policy you buy yourself may still be escrowed. If coverage lapses or proves inadequate, the lender sends a 45-day notice and then force-places a policy at your cost, refunding overlap if you prove coverage. NFIP pricing under Risk Rating 2.0 is building-specific, with most annual increases capped at 18% — higher for some older non-primary residences — and the annual surcharge is $250 on a non-primary residence against $25 on a primary one. NFIP authorization has lapsed for short periods in the past, which can freeze new policies and stall closings; ask the lender what its contingency is if the program is in lapse on your closing date.
Questions for the association before you lock
Request the RCBAP declarations page, the building’s replacement cost estimate, the deductible, recent claims history and the last elevation certificate. Compare the coverage per unit with your loan amount. A unit-level policy covers your interior improvements and contents, up to $100,000 for contents, and a standard HO-6 excludes flood entirely.
What to check
- Get the RCBAP declarations page and divide building coverage by the number of units; compare it with your loan balance before the appraisal is ordered.
- Budget a unit-level NFIP or private flood policy if the master policy is below replacement cost, and ask the lender how it calculates the gap.
- Confirm whether your flood premium will be escrowed; the exemption applies only when the association pays it through dues.
- Ask whether the building has had flood claims and whether the 80% coinsurance clause is met, since underinsurance lands on owners as assessments.
Frequently asked questions
Is flood insurance required on a second home in a flood zone?
Yes. The Flood Disaster Protection Act applies to any loan secured by a building in a Special Flood Hazard Area in a participating community, regardless of occupancy. For a condo unit the lender checks the association’s RCBAP against your loan balance and insurable share, and requires a unit policy for any shortfall. Coverage must be maintained for the life of the loan.
Does my HO-6 condo policy cover flood damage?
No. A standard HO-6 policy excludes flood. Building coverage for flooding comes from the association’s RCBAP, and anything the master policy does not reach — interior improvements beyond its scope, contents, or a coverage gap — requires a separate NFIP dwelling policy for the unit or a private flood policy that meets the regulatory definition.
