Flood insurance for condos: the RCBAP, unit policies, and the gap between them

Condominium flood insurance is split between two policies by design: the association insures the building under a Residential Condominium Building Association Policy (RCBAP), and each unit owner can insure their own contents — and their walls-in building interest — under an individual dwelling-form policy. The RCBAP’s maximum building coverage is the number of units multiplied by $250,000, or the building’s replacement cost, whichever is less. Whether the association actually buys near that ceiling is the fact a unit owner most needs to know, because the RCBAP carries a coinsurance penalty and unit owners absorb shortfalls through assessments.

The association’s policy: RCBAP

The RCBAP is a distinct federal form for residential condo associations in NFIP communities. Its structure:

What it covers. The entire building, including units and their standard fixtures (the form reaches into units for originally installed items like cabinets and plumbing), plus association-owned contents in common areas.
The ceiling. Building coverage up to the lesser of replacement cost or units × $250,000; association contents up to $100,000 per building.
The coinsurance clause — the RCBAP’s sharpest edge. If the association insures the building for less than 80% of its replacement cost (and less than the maximum), claims are penalized proportionally: the policy pays only the insured-to-required ratio of each loss. An association carrying half the required amount collects roughly half of a partial loss — a mechanism unit owners rarely see until after the water.
Eligibility. The building must be residential (in the main); mixed-use and non-residential condominium buildings use the General Property form with lower limits — see flood insurance for businesses.

The unit owner’s policy

An individual condo unit owner can buy a dwelling-form policy covering:

Contents up to $100,000 — furniture, clothing, electronics — at actual cash value, with the same basement limitations as any NFIP policy.
Building coverage up to $250,000 on the owner’s building interest — improvements within the unit, and importantly, excess building coverage that can sit above the RCBAP for the owner’s unit share when the association’s coverage falls short.

NFIP rules coordinate the two layers: the RCBAP is primary for building losses; a unit owner’s building coverage responds for what the association’s policy did not cover on that unit, subject to its own limit.

The gap: assessments

When flood damage exceeds the RCBAP’s payment — through the coinsurance penalty, underinsured limits, or the deductible — associations levy special assessments on owners. The NFIP dwelling form’s loss-assessment coverage is narrow: it can respond to assessments for building damage within specific conditions, and does not respond where the assessment exists because the association carried too little coverage relative to the coinsurance requirement. Homeowners (HO-6) loss-assessment endorsements generally exclude flood entirely. In practice, an assessment after an underinsured flood lands substantially uninsured — which is why the association’s declarations page and replacement-cost appraisal are the documents that matter most in condo flood diligence.

Lenders and condos

A mortgage on a unit in a Special Flood Hazard Area triggers the mandatory purchase rule. Lenders evaluate the RCBAP first: coverage at replacement cost or units × $250,000 typically satisfies the unit’s requirement; a shortfall pushes the lender to require unit-owner building coverage on top. The 30-day waiting period and loan-closing exception apply to unit policies as usual.

Frequently asked questions

Does a condo association have to buy flood insurance?

Federal law does not require it directly; lender requirements on units, state condo statutes, and the association’s bylaws are what compel coverage in practice. In SFHA buildings with mortgaged units, an absent or thin RCBAP shifts requirements onto every borrowing owner.

What does the RCBAP not cover for a unit owner?

The owner’s contents, improvements beyond originally installed items, additional living expenses (nothing in the NFIP covers those), and assessment exposure from association underinsurance. The first two are insurable on a unit policy; the last one largely is not.

How much unit coverage makes sense given a strong RCBAP?

That is a coverage-structure question this site describes but does not answer for any individual: the mechanics above — RCBAP limit versus replacement cost, coinsurance status, deductible size, contents value — are the inputs a comparison weighs. Premium context for the covered states is in how much is flood insurance?

Is a townhouse a condo for flood insurance?

The legal form of ownership controls, not the architecture. Fee-simple townhouses insure as single-family dwellings; condominium-regime townhouses fall under association/unit structures. The declarations and deed answer it.

Do these rules apply to private flood insurance on condos?

No — private insurers write their own condo forms, some with association terms differing sharply from the RCBAP (no coinsurance clause, or different unit coordination). The NFIP vs. private comparison covers the structural differences.
