New York insurance risk
Insurance is among the most volatile risks in New York condo and co-op documents today. The statutory requirement is modest — under RPL § 339-bb the condo board must insure the building if the declaration, bylaws, or a majority of owners require it, and in practice nearly all bylaws mandate a master replacement-cost policy.

The market behind that requirement is stressed: 20%+ premium increases are routine, several carriers have exited or curtailed the NYC multifamily market, and underwriters now scrutinize maintenance and open DOB violations in detail. Flood is generally excluded, and post-Sandy exposure is materially understated by legacy FEMA maps. For a New York buyer, the master policy is both a risk document and a financing document — its deductibles and coverage gaps can affect mortgage warrantability and what you need in your own HO-6.
What the statute requires (and what the bylaws really drive)
RPL § 339-bb is permissive at the floor: the board must insure the building against fire and other hazards if required by the declaration, bylaws, or a majority of owners, and for qualified leasehold condominiums full replacement-cost insurance is mandatory and annually updated. In practice the bylaws and lender (Fannie/Freddie) requirements drive coverage levels. Each unit owner retains the right to insure their own unit. Co-ops have no condo-style statute — insurance flows from the proprietary lease and bylaws, and the corporation typically carries a master, liability, D&O, and fidelity/crime policy.
The hard market
The NYC co-op/condo market is in a pronounced hard market through 2025–2026. Premium increases of 20%+ are routine, and buildings leaving preferred programs have seen 50%–200% jumps. Several insurers have exited or curtailed the market, and renewals are being declined for buildings with open issues or recent claims. Underwriters now scrutinize cracked sidewalks, roof flashing, open DOB and Local Law violations, and water-damage history — so the building's compliance posture directly raises or lowers its insurance risk, linking the Local Law stack to the master policy.
Flood: the peril that usually isn't covered
Standard master and unit policies generally exclude flood. After Hurricane Sandy, roughly 65% of the inundated area lay outside the legacy FEMA-mapped flood zone, so flood risk is materially understated by old maps. Coastal co-ops and condos in Lower Manhattan, the Rockaways, Coney Island, Red Hook, Staten Island's East Shore, and on Long Island are most exposed. Confirm the FEMA zone, check the NYC Flood Hazard Mapper, and verify whether the association carries flood coverage on common areas — NFIP or private flood is usually needed separately.
Financing linkage and your HO-6
Master-policy deductibles and coverage gaps can block conventional financing under Fannie Mae and Freddie Mac project standards — deductible caps and required fidelity coverage for larger projects, for example — and a non-warrantable posture can shrink the buyer pool and depress resale value. Because deductibles are high and flood is often excluded, your own HO-6 matters: pay attention to loss-assessment coverage (which pays your share when the association passes a deductible or uncovered loss to owners) and to flood coverage where the building is exposed.

- Read the master declarations: carrier, limits, deductibles, and any non-renewal notice

- Check whether the deductible could affect Fannie/Freddie warrantability and financing
- Confirm whether the building carries fidelity/crime and D&O coverage
- Determine the FEMA flood zone and check the NYC Flood Hazard Mapper
- Confirm whether the association carries flood coverage on common areas
- Review open DOB and Local Law violations that could raise insurance risk
- Review your own HO-6 loss-assessment limit against the master deductible
- Consider individual flood coverage for coastal or Sandy-exposed buildings
