A New York homeowners policy that has been in force 60 days is protected for three years: it can be cancelled or non-renewed only for a short list of reasons, and a non-renewal needs written notice 45 to 60 days ahead with the specific reason. If the notice stands, I shop the standard market first, then the Coastal Market Assistance Program, then the state's FAIR Plan (NYPIUA) with a wraparound policy, then the excess line market. Flood and sewer backup are separate purchases every time.
Check the notice before you shop
New York Insurance Law section 3425 sets a three-year required policy period for homeowners policies. The Department of Financial Services (DFS) explains it this way: in the first 60 days an insurer can cancel if the notice states the specific reason. After that, for three years, it can cancel or refuse to renew only for the reasons the statute lists:
- NonpaymentDFS says paying within 15 days of the mailing of the cancellation notice stops the cancellation.
- Fraud or material misrepresentationIn obtaining the policy or presenting a claim.
- Acts that increase the hazardA criminal conviction for them, or willful or reckless acts or omissions.
- Physical changes to the propertyChanges after the policy was issued that make the home uninsurable under the insurer's own uniformly applied standards.
- A finding by the SuperintendentThat continuing the policy would violate the Insurance Law.
At the end of the three years the insurer may decline to renew, but it must mail written notice at least 45 and not more than 60 days before the policy ends, and the notice has to state the specific reason. So the first thing I read is the date the policy was first issued and the date on the letter. A notice that lands in the middle of the three-year period for a reason that is not on the list, or one mailed too late, is worth a complaint to DFS through its online consumer complaint form before you pay for a replacement. More detail is on the New York non-renewal rules page.
The same statute also slows insurers that want to leave. One that plans a material reduction in its homeowners policies must file a plan with the Superintendent at least sixty days ahead, and the law tells the Superintendent to weigh the effect on areas within one mile of a saltwater shoreline, canal or bay in Queens, Kings (Brooklyn), Richmond (Staten Island) and Bronx counties.
Two different floods: Sandy and Ida
Underwriters look at a New York City address through two storms. Sandy, in October 2012, was salt water. The National Hurricane Center's report puts the storm tide at the Battery at 14.06 feet above mean lower low water, more than four feet over the previous record in a gauge history going back to 1920. Water stood four to nine feet above ground on parts of Staten Island and Manhattan and three to six feet in Brooklyn and Queens. At least 21 people died on Staten Island from the surge, and a fire in Breezy Point on the Rockaway peninsula destroyed at least 100 homes while the streets were under water.
Ida, in September 2021, was rain. The Hurricane Center's report lists a storm total of 9.64 inches on Staten Island and 7.19 inches at Central Park, and says eleven people in New York drowned in their homes or apartments. Ida's water came up through streets, drains and basement doors, far from any beach.
The flood maps have not caught up with either storm. According to the City's flood maps site, FEMA issued preliminary maps in 2013 and 2015, the City appealed them in June 2015, and in October 2016 FEMA agreed to revise them. Until new maps are issued the 2007 effective maps remain the insurance maps, while the City's Building Code already makes new and substantially improved buildings use the preliminary ones. As of November 2026 that site still describes the revised maps as on the way. A house can sit outside the mapped high-risk zone and still be a house that flooded.
The hurricane deductible, and when it applies
DFS says some insurers require a hurricane deductible on homes in all five boroughs, commonly one to five percent of the dwelling amount. New York's rule on when it applies is narrow. Under the amended Insurance Regulation 159, adopted in July 2025, the deductible is triggered only when the National Weather Service determines that the hurricane made landfall in New York State, and it applies only to wind damage from 12 hours before that landfall until 12 hours after the last hurricane watch or warning for the state is cancelled. The percentage and the matching dollar figure have to appear on the declarations page.
Sandy shows how much the wording matters. After that storm DFS told insurers that hurricane deductibles should not be triggered, because Sandy did not have sustained hurricane-force winds when it reached New York. A separate windstorm deductible is a different thing: DFS describes it as optional and triggered by wind of any speed, so I check which of the two a quote carries. The longer explanation is on how hurricane deductibles work in New York.
C-MAP, then NYPIUA, then excess line
When the standard market says no, the next stop is the Coastal Market Assistance Program. DFS describes C-MAP as a voluntary network of insurers and producers, administered by the New York Property Insurance Underwriting Association (NYPIUA), for owner-occupied one- to four-family homes, apartments and condominium units near the shore. In Brooklyn, Queens and Staten Island that generally means within one mile of the water; in the Bronx, within 2,500 feet. You need a non-renewal, cancellation or conditional non-renewal notice for a reason other than nonpayment; on a purchase, the application has to identify the home's prior insurer.
NYPIUA is the state's FAIR Plan, an association of every insurer that sells fire insurance in New York. Its Basic form covers fire, wind including hurricane, hail, explosion, riot, aircraft, vehicles, smoke and vandalism. Its Broad form adds perils such as weight of ice and snow, freezing and accidental discharge of water. By its own description it does not offer liability, flood or theft coverage, it generally pays actual cash value, and it tops out at six hundred thousand dollars on a one- to four-family dwelling and two hundred fifty thousand on contents and living expense combined. It will not take a house with unsafe wiring or heating, unrepaired damage or open code violations. Broad form policies in the five boroughs carry a two percent hurricane deductible tied to a Category 2 or stronger landfall in the state.
The fix for those gaps is a wraparound: a standard insurer's policy endorsed to sit around the NYPIUA policy, adding liability, theft and personal property, and allowing replacement cost on the building. Past that is the excess line market, which DFS says is open only after three admitted insurers decline, and which is not backed by the state's security fund if the insurer fails. I say that in writing before anyone signs.
Basements, sewers and the gap between two policies
A finished basement or garden-level unit is where New York City claims go wrong. DFS explains that water backing up through a sewer or sump comes from below the foundation, so it is not flood, and it is not covered by a standard homeowners policy either unless you buy the backup endorsement, which pays up to a limit you choose. A flood policy, in turn, is unlikely to pay for a sump pump that failed because of a flood. Both pieces have to be bought on purpose.
The City's Department of Environmental Protection adds two things worth knowing. The pipe from the house to the sewer main in the street belongs to the owner, who pays to repair it. And an owner who believes a backup was the City's fault has 90 days to file a claim with the Comptroller. Report a backup to 311 first and keep the tracking number. See sewer backup coverage and flood insurance.
Brownstones, small multi-families, co-ops and condos
An owner-occupied two- to four-family house can usually stay on a homeowners form with the rental units disclosed; once the owner moves out it becomes a landlord policy. Attached brick and brownstone rowhouses are old buildings, so the questions are the roof, wiring, plumbing and heat, and whether the limit reflects what it costs to rebuild masonry on a narrow lot. In a co-op or condo the building's master policy covers the structure and common areas, and a unit-owner policy covers your improvements, belongings, liability and assessments. C-MAP takes condominium units as well as houses.
What I need to quote
The address, the non-renewal or cancellation letter, the current declarations page, year built, number of units and who lives in them, the age of the roof, wiring, plumbing and heating, whether the basement is finished, any claims in the last five years, and the date coverage has to start. If there is a lender or a closing, tell me the date and I work backward from it.
Common questions
Can my insurer drop my New York City home in the middle of the policy?
After the first 60 days, only for the reasons Insurance Law section 3425 lists, such as nonpayment, fraud or physical changes that make the home uninsurable. That protection runs for three years from when the policy was first issued or renewed.
How much notice do I get for a non-renewal in New York?
Written notice at least 45 and not more than 60 days before the policy ends, stating the specific reason. If you think the reason is unfair or the notice is late, you can file a complaint with the Department of Financial Services.
Who insures a house near the water in Brooklyn, Queens or Staten Island?
Standard insurers still write many of them. If they will not, the Coastal Market Assistance Program serves owner-occupied homes generally within one mile of the shore, and NYPIUA, the state FAIR Plan, writes fire and wind coverage behind it.
Does the New York FAIR Plan cover liability or flood?
No. NYPIUA says it does not offer liability, flood or theft coverage. A wraparound policy from a standard insurer adds liability and theft, and flood is a separate policy.
Did hurricane deductibles apply to Sandy in New York?
DFS told insurers in 2012 that they should not be triggered, because Sandy did not have sustained hurricane-force winds when it reached New York. Today's rule ties the deductible to a hurricane landfall in New York State.
Is basement flooding covered by my homeowners policy?
Flood is excluded and needs its own policy. Water backing up through a sewer or sump is not flood, and is covered only if you add the backup endorsement.
My house is not in a FEMA flood zone. Do I still need flood insurance?
A lender may not require it, but the City's maps are still being revised and Ida flooded homes far from the coast. A policy from the National Flood Insurance Program usually has a 30-day waiting period, so buy it before the forecast.
General information about home insurance in New York City as of November 2026, not legal advice. Cancellation and non-renewal rules are set by New York Insurance Law section 3425, hurricane deductibles by Insurance Regulation 159, and C-MAP and NYPIUA eligibility by those programs; all of them change. Storm figures are from National Hurricane Center reports. Coverage depends on the policy issued. Coverage depends on underwriting and the terms, conditions and exclusions of the policy actually issued.
