Long Island Insurance Guide
Last reviewed: July 2026
TL;DR
Long Island homeowners face some of the most difficult insurance conditions in New York. Carriers have pulled back from coastal ZIP codes, premiums have climbed sharply, and a standard homeowners policy won't cover flood or storm surge. These guides explain what's happening and what to do about it.

What's happening on Long Island
The insurance market for Long Island homeowners has shifted significantly since 2019. Carriers that once wrote broadly across Nassau and Suffolk have tightened underwriting, raised deductibles, and in some cases stopped writing new business in coastal ZIP codes entirely.
The causes are straightforward: rising reinsurance costs driven by national catastrophe losses, construction cost inflation that has pushed replacement values above historical policy limits, and a concentration of coastal exposure that makes Long Island disproportionately risky for carriers with national books of business.
The result for homeowners is higher premiums, stricter roof-age requirements, larger hurricane deductibles, and in some cases non-renewal notices with little warning. The standard path of renewing with the same carrier no longer works for many properties near the water.

Force-placed insurance
The federal 45-day notice clock, why New York regulated this after a 2013 DFS investigation found 2-10x pricing abuse, and what to do if it happens to you.
Town-level guides
Insurance conditions vary block by block, not just town by town. These guides are built on live FEMA flood-layer queries, NFIP claims records, and Census housing data for each place.
Long Beach home insurance
The barrier island: AE and VE flood zones, 9,653 NFIP claims in ZIP 11561, pre-FIRM housing, and the whole-island C-MAP band.
Freeport home insurance
One village, two flood realities: high-risk zones toward the bay and canals, minimal-hazard blocks inland, and what Sandy changed on the Nautical Mile.
Babylon home insurance
Three ZIPs share the name, not the flood record: the village's bay blocks carry 2,714 NFIP claims against North Babylon's 53.
Southampton home insurance
A village where seasonal homes outnumber occupied ones, median value tops $2 million, and occupancy is the first underwriting question.
Huntington home insurance
Long Island's other shore: Long Island Sound exposure means 20x fewer NFIP claims than Long Beach or Freeport, but the same rules still apply.
Oyster Bay home insurance
The north shore is not one market: Bayville logs more than 12 times the NFIP claims of the Oyster Bay hamlet next door, on the same Sound.
Lindenhurst home insurance
One of Long Island's highest flood-claims ZIPs, yet only about 14% of the current FEMA map is a mandatory-purchase zone. The map and the claims don't match.
Massapequa home insurance
The highest average NFIP payout per claim of any town we've compared, even with fewer total claims than Long Beach or Freeport.
Bay Shore home insurance
One ZIP code, two flood markets: mainland Bay Shore and ferry-only Fire Island communities share a claims total, but a FEMA query found the barrier-beach side entirely mandatory-purchase.
East Hampton home insurance
Downtown Montauk was rebuilt after the 1938 hurricane on the same oceanfront the federal government now renourishes every few years, and the FEMA map still calls most of it mandatory-purchase.
More east end and north shore towns follow, two to three per week, each with real local data.
