What Insurance Do You Need to Live on Long Island in 2026?

Living on Long Island means insuring against things most of the country never thinks about: a hurricane deductible written as a percentage, a basement that floods from the street, a commute on the Long Island Expressway and a home worth more to rebuild than it was to buy. Whether you rent in Hicksville, own a Cape in Ronkonkoma or a bayfront house in Massapequa, this guide shows which policies your household needs and links to the deep-dive article for each.

What insurance does a Long Island household actually need?

Every Long Island household needs auto insurance for each registered car and a property policy matched to how it lives (homeowners, condo, co-op, renters or landlord), and most should also weigh flood and umbrella coverage.

Long Island is a big, mostly owner-occupied place. The U.S. Census Bureau's July 1, 2025 estimates put Nassau County at 1,398,939 residents and Suffolk County at 1,546,090, close to 2.95 million people combined (Census QuickFacts, Vintage 2025). The Census Bureau's 2020–2024 American Community Survey figures show 81.9% of Nassau homes and 82.2% of Suffolk homes are owner-occupied. The right mix depends on who's in the home and what they own; use the checklist below as a starting point.

How much car insurance do you need on Long Island?

New York requires 25/50/10 liability, $50,000 of no-fault (PIP) and uninsured motorist coverage on every registered car, but most Long Island households with a home or savings should carry far higher liability limits with matching SUM.

New York DFS lists the required minimums as $25,000 for bodily injury to one person, $50,000 for bodily injury to two or more people, $10,000 for damage to others' property and $50,000 for Personal Injury Protection, also called no-fault, with uninsured motorist protection subject to the same minimums (NY DFS). No-fault pays your own medical bills and lost wages regardless of who caused the crash; our plain-English guide to New York no-fault walks through what it pays and what it doesn't.

Those minimums are a floor. DFS's own auto guidance says drivers "should seriously consider purchasing higher limits of bodily injury liability coverage," gives $100,000/$300,000 as an example, and notes that the $10,000 property damage minimum may be too low because many cars cost far more to fix (NY DFS auto insurance). Our breakdown of what 25/50/10 really covers shows where the minimum runs out.

The other coverage we push for is SUM, Supplementary Uninsured/Underinsured Motorists. DFS explains that SUM applies when the at-fault driver is insured but carries lower limits than you, and that it can't exceed your own bodily injury limits.

Teen drivers on Long Island

Families with new drivers face Long Island-specific rules. Under DMV's graduated license law, junior license holders can drive in Nassau and Suffolk counties only under direct supervision by a parent, guardian, authorized adult or driving instructor who is at least 21, with limited exceptions such as driving directly between home and work (NY DMV). DFS notes drivers licensed less than three years can face an inexperienced operator surcharge. See our New York good student discount guide, and for any driver, the defensive driving course discount: DMV says completing an approved course reduces the base rate of your auto insurance by 10% each year for three years (NY DMV PIRP).

What should a Long Island homeowners policy include?

A Long Island homeowners policy should insure the house to its full replacement cost, show the hurricane deductible as a dollar figure you can afford, and add a sewer backup endorsement if you have a basement or sump pump.

Wind and hurricanes. New York DFS says some insurers apply hurricane deductibles in the five boroughs, Nassau, Suffolk and coastal Westchester, commonly 1% to 5% of the dwelling amount, and DFS requires insurers to show that deductible as a dollar amount on the declarations page (NY DFS storm preparedness) (NY DFS homeowners guide). For policies issued or renewed since February 2, 2026, under DFS Regulation 159 as amended in 2025, a hurricane deductible is triggered only when the National Weather Service determines a hurricane made landfall in New York State (NY DFS Regulation 159). On a $700,000 dwelling limit, a 2% deductible means the first $14,000 of covered hurricane wind damage is yours. Our guide to hurricane damage on Long Island covers wind versus storm surge.

Sewer backup. The standard ISO homeowners form many policies follow excludes water that backs up through sewers or drains or overflows from a sump pump (ISO HO-3 sample form, via III). DFS confirms some insurers sell a sewer backup endorsement, but it isn't standard. Read our sewer backup and sump pump guide.

Replacement cost. DFS explains that if you buy replacement cost coverage and insure the home for at least 80% of its replacement cost, a covered loss is generally settled at replacement cost; below 80%, you can be paid less. On Long Island, what it costs to rebuild often has little to do with what the house would sell for, as our replacement cost vs. market value explainer shows.

Non-renewal. New York insurers must give 45 to 60 days' notice before non-renewing a homeowners policy (NY DFS). If you get that letter, our Long Island non-renewal playbook explains what to do first. The flagship complete Long Island home insurance guide ties all of this together, and our home insurance page is the place to start a quote.

Fallen trees. Wind-driven tree damage to the house, garage or fence is generally a covered homeowners loss, but tree removal is often capped and a tree that falls without hitting anything usually isn't covered. Our guide to fallen tree damage on Long Island walks through neighbor trees, cars and dead-tree denials.

Your town. The same checklist plays out differently by address. A South Shore village like Patchogue on the Great South Bay weighs flood and wind most heavily, while an inland village like Lake Grove has no storm-surge zone but its own tree, cesspool and rental questions.

Do you need flood insurance on Long Island?

Flood insurance is required on Long Island if your home is in a FEMA Special Flood Hazard Area and you have a government-backed mortgage, and it's worth pricing for nearly everyone else, because homeowners, condo and renters policies exclude flood.

FloodSmart, FEMA's consumer site, says you're required to carry flood insurance if you own a home in a Special Flood Hazard Area and have a government-backed mortgage, and that some lenders require it even outside high-risk areas (FloodSmart eligibility). DFS states plainly that flood losses aren't covered in standard homeowners or unit policies.

Here's how Long Island looks in FEMA's own numbers, current to August 3, 2026:

Two details stand out. About 6.6% of Long Island's residential buildings sit in a mapped high-risk zone, yet roughly a third of the NFIP policies in force cover homes outside those zones, which suggests many owners outside those zones carry flood coverage even where it isn't federally required. Our explainer on Long Island flood zones AE, VE and X shows how to read your map.

NFIP residential policies top out at $250,000 for the building and $100,000 for contents, personal property kept in basements isn't covered, and new coverage generally starts 30 days after purchase, with exceptions such as buying at a mortgage closing (FloodSmart policy terms). Start with whether your Long Island home needs flood insurance, then see what flood insurance costs on Long Island.

What if no insurer will write your Long Island home?

If the regular market won't insure your Long Island home, the New York Property Insurance Underwriting Association (NYPIUA) offers fire and extended coverage as a last resort, and the Coastal Market Assistance Program (C-MAP) helps coastal owners find a regular insurer first.

DFS describes C-MAP as a voluntary network of insurers and producers that helps homeowners in coastal areas, for owner-occupied one-to-four family homes, apartment units and condo units in the Bronx, Brooklyn, Nassau, Queens, Staten Island, Suffolk and Westchester (NY DFS). NYPIUA is an association of all insurers that sell fire insurance in New York.

NYPIUA has real gaps. Its policies don't include liability, flood or theft coverage, are generally written on an actual cash value basis, and its one-to-four family dwelling limit is $600,000 for an occupied building; the Broad Form carries a 2% hurricane deductible in listed counties (NYPIUA product information). Anyone on NYPIUA needs liability and flood arranged separately.

What insurance do Long Island condo and co-op owners need?

Long Island condo owners need an HO-6 unit-owner policy and co-op shareholders need a co-op unit-owner policy, because the association's or cooperative's master policy covers the building, not your belongings, improvements or personal liability.

DFS says separately purchased condominium insurance covers the unit owner and is similar to renters insurance, and that cooperative policies insure the contents of a unit and provide personal liability coverage. The part owners miss is the line between the master policy and their own. Master policies vary in how much of the unit interior they cover, so upgrades you've made are often your responsibility.

Water is the claim we see most in multi-unit buildings, from a neighbor's failed supply line to a leak from the unit above. Our Long Island condo insurance guide, our guide to condo water damage claims and our co-op insurance guide explain how to read the bylaws or proprietary lease and size your coverage. Ready to price it? Our condo insurance page starts the quote.

Do Long Island renters and landlords need their own insurance?

Yes: Long Island renters need their own renters policy because a landlord's insurance doesn't cover a tenant's belongings, and Long Island landlords need a landlord (dwelling) policy because a homeowners policy isn't built for a rented home.

DFS is direct about it: "A landlord does not provide insurance for a tenant's personal property," and many uninsured renters wrongly assume otherwise. DFS's Homeowners and Tenants Insurance Guide (checked October 2026) puts a basic renters policy at about $300 a year for roughly $50,000 of property protection (NY DFS). See our Long Island renters insurance guide or our renters quote page.

If you own a two-family in Hempstead, rent out a basement apartment or have moved and kept the old house as a rental, the property needs a policy written for a landlord. Our Long Island landlord insurance guide explains the forms, and our second home guide covers beach houses rented a few weeks each summer. Quotes start on our landlord insurance page.

When does a Long Island household need umbrella insurance?

A Long Island household needs umbrella insurance when its home equity, savings and future income are worth more than the liability limits on its auto and home policies, which is common in Nassau and Suffolk.

The NAIC describes a personal umbrella as coverage for liability and legal defense costs that exceed what your primary policies pay, and notes it doesn't cover damage to your own home or vehicle (NAIC).

On Long Island, the triggers we watch for are a teen driver joining the policy, a pool or trampoline, a dog, a boat, a rental property, and simply a high-value home. Umbrella insurers usually require set underlying liability limits on your auto and home policies, so the umbrella and the policies beneath it have to be built together. Our Long Island umbrella insurance guide covers who needs one and how much to carry.

Do ATVs and boats on Long Island need separate insurance?

Yes, in most cases: New York requires liability insurance on an ATV ridden anywhere off the owner's land, and a standard homeowners policy sharply limits coverage for boats, so both usually need their own policy.

ATVs. New York Vehicle and Traffic Law §2407 requires an ATV operated off the owner's land to be covered by liability insurance (NY VTL §2407), and DMV says you need a valid New York registration to ride an ATV in the state, with narrow exceptions (NY DMV). Our New York ATV and off-road insurance guide covers UTVs, dirt bikes and snowmobiles too.

Boats. The standard ISO homeowners form limits watercraft, including trailers and motors, to $1,500 as personal property, and its liability section excludes owned outboard motors over 25 total horsepower unless the motor is declared to the insurer or reported within the form's deadline, with other limits for inboard and sailing vessels. Boaters also have a licensing rule to know: under Brianna's Law, a safe boating certificate has been required of all motorized boat operators, regardless of age, since January 1, 2025 (NY State Parks). Ask us to review your boat, its trailer and your umbrella together.

Jewelry, watches and collections are the other common add-on, since homeowners forms cap theft of those items; our jewelry and valuables guide explains scheduling them.

The bottom line on insurance for Long Island households

A Long Island household's insurance starts with two policies, auto and a property policy matched to how you live, and then closes the gaps that this island creates: higher auto liability with matching SUM, a hurricane deductible you can afford, sewer backup, replacement cost, flood, and an umbrella over all of it once you have something to protect.

Flood is always separate. About 56,800 Nassau and Suffolk residential buildings sit in FEMA high-risk zones, and thousands of owners outside them carry flood coverage anyway. If the regular market says no, NYPIUA is a fallback with real gaps, including no liability.
