New York condo insurance requirements
Insurance is among the most volatile risks in a New York condo or co-op purchase, and the law leans on the governing documents rather than fixed dollar mandates. Under RPL § 339-bb the condo board must insure the building against fire and other hazards if the declaration, bylaws, or a majority of owners require it — and for qualified leasehold condominiums full replacement-cost coverage is mandatory and annually updated.

In practice nearly all condo bylaws, plus Fannie Mae and Freddie Mac requirements, drive a master replacement-cost policy. The market behind that requirement is stressed: 20%+ premium increases are routine, carriers have exited or curtailed the NYC multifamily market, underwriters now scrutinize open DOB and Local Law violations, and flood is generally excluded with post-Sandy exposure understated by legacy FEMA maps. For a buyer, the master policy is both a risk document and a financing document.
What RPL § 339-bb actually requires
Section 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 unit owners, and for qualified leasehold condominiums full replacement-cost insurance is mandatory and annually updated. Each unit owner keeps the right to insure their own unit through an HO-6. In practice the bylaws and lender (Fannie/Freddie) requirements drive coverage levels far more than the statute. Co-ops have no condo-style insurance statute — coverage flows from the proprietary lease and bylaws, and the corporation typically carries a master property, liability, D&O, and fidelity/crime policy, with shareholders carrying their own unit policies. Confirm the master policy is replacement cost and meets the bylaws' requirement.
The hard market
The NYC co-op/condo market is in a pronounced hard market through 2025–2026. Premium increases of 20%+ are now routine, and buildings leaving preferred programs have seen 50%–200% jumps. Several insurers have exited or curtailed the NYC multifamily market, and renewals are being declined for buildings with open issues or recent claims. Underwriters now scrutinize cracked sidewalks, deteriorating roof flashing, open DOB and Local Law violations, and water-damage claim history — so the building's compliance posture directly raises or lowers its insurance risk, linking the Local Law stack to the master policy. Ask whether the building was non-renewed or absorbed a major increase at its last renewal, and read the minutes for the discussion behind it.
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 maps that went unchanged for decades. 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, and updated maps now incorporate future sea-level rise. 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, and water damage from aging systems is already the leading loss driver in the older stock.
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 insurance 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. For co-ops, insurance costs flow into maintenance and interact with the underlying-mortgage lender's covenants; for condos they flow into common charges and special assessments.
