Hamptons home insurance: HO-3 vs HO-5, jewelry, and umbrella sizing

A Hamptons house is usually the most underinsured thing its owner has. Not because the coverage limit looks small — a $3 million dwelling limit sounds like plenty — but because the policy underneath it was often written the same way you’d write a policy for a colonial in Nassau County, and the East End does not price like Nassau County.

Here’s how we think about the three decisions that matter: the policy form, the jewelry and valuables schedule, and the umbrella on top.

Why East End replacement cost is its own number

Rebuilding in Southampton, East Hampton, or Sag Harbor runs roughly 25–40% above comparable construction elsewhere on Long Island. Every trade is more expensive out east: contractors are seasonal and booked, materials get trucked in, and the finishes in these homes — cedar shake roofs, custom millwork, imported stone — don’t rebuild at tract-home rates. Add coastal wind-load code requirements and, for many parcels south of the highway, flood-zone construction standards, and the per-square-foot number climbs fast.

The practical consequence: if your dwelling limit was set from a purchase price or a Zestimate, it’s probably wrong. Market value in the Hamptons is mostly land. A $6 million property might carry $2.5 million of actual structure — or a $4 million property might have a structure that costs $3.5 million to rebuild to spec. The only honest way to set the limit is a replacement-cost estimate built from the home’s actual construction details, updated every few years. This is the kind of pricing problem Kelly’s actuarial background makes her allergic to guessing at: the inputs are knowable, so use them.

Two endorsements matter here. Extended replacement cost (typically 25–50% above the dwelling limit) absorbs the cost spike that follows any regional storm event, when every contractor on the East End is booked and pricing accordingly. Ordinance or law coverage pays the cost of rebuilding to current wind and flood code rather than to the code your 1978 house was built under — and after a major loss, the town will not let you rebuild to 1978 code.

HO-3 vs HO-5: what the upgrade actually buys

An HO-3 covers the structure on an open-perils basis but your contents on a named-perils basis — if the cause of loss isn’t on the list, contents aren’t covered. An HO-5 covers both structure and contents open-perils, and typically pays contents at replacement cost rather than depreciated actual cash value.

For a starter apartment, the difference is academic. For a Hamptons house, it isn’t. These homes hold serious contents — art, wine, instruments, furniture that was made, not bought — and the loss scenarios that hit second homes (mysterious disappearance, accidental damage during the eight months you’re not there, water events discovered late) are exactly the ones named-perils forms handle worst. If the home qualifies for HO-5, the premium difference is usually modest relative to the dwelling premium, and it’s the correct form for this class of house.

One New York-specific wrinkle: nearly every carrier writing coastal Suffolk County attaches a separate hurricane or windstorm deductible, usually 2–5% of the dwelling limit rather than a flat dollar amount. On a $3 million dwelling limit, a 5% hurricane deductible is $150,000 out of pocket before the policy pays. That deductible is negotiable at placement — carriers offer buy-down options — and it’s worth real money to know your number before storm season instead of after. And remember that no HO-3 or HO-5 covers flood; south of Montauk Highway, a separate flood policy (NFIP plus excess, or private) is part of the package, not an optional extra.

Jewelry and valuables: the sublimit is smaller than you think

Standard homeowners forms cap theft of jewelry at $1,500 to $2,500 total — not per item. Furs, watches, silverware, and firearms carry similar sublimits. If there’s an engagement ring in the house, that sublimit is exhausted before you get to the second piece.

The fix is scheduling: each significant item listed on the policy with an appraised value, covered for essentially all risk including mysterious disappearance, with no deductible. Insist on agreed-value scheduling, where the carrier commits to the appraised figure up front, rather than leaving the payout to a post-loss valuation argument. Keep appraisals current — every three to five years — because a schedule based on a 2015 appraisal pays 2015 prices.

For art and wine collections beyond what a schedule handles gracefully, a valuable-articles floater or standalone collections policy is the right structure. Blanket coverage with per-item caps works for the mid-tier; individually scheduled coverage for the significant pieces.

The umbrella is not optional at this asset level

Liability is the exposure that scales fastest with a Hamptons property. A pool, a dock, seasonal staff, houseguests all summer, teenage drivers, maybe a short-term rental week or two — each is a liability multiplier, and New York juries are not famous for small verdicts.

Here’s what most agencies miss: they’ll write the $2 million umbrella and stop, without checking the underlying policies it sits on. An umbrella has attachment points — it typically requires $250,000/$500,000 or $300,000 on the underlying auto and homeowners liability. If your auto policy is still carrying $100,000/$300,000 limits, there’s a gap between where your auto policy stops and where the umbrella starts, and that gap is yours. The umbrella, the home, and the autos have to be checked against each other as a system, every renewal, not sold as three separate line items.

Sizing is a net-worth exercise: the umbrella should roughly cover what a plaintiff could reach — total assets plus a measure of future income. For most Hamptons owners that’s $5 million and up, and the pricing is favorable: umbrella coverage is among the cheapest insurance per dollar of protection you can buy, often a few hundred dollars per additional million. If any staff work at the property — housekeeper, caretaker, seasonal landscaper on your payroll — New York requires workers’ compensation coverage for domestic employees working 40 or more hours a week for you, and that’s a separate policy, not something the homeowners form absorbs.

One system, reviewed together

The pattern in everything above: a high-value home isn’t one policy, it’s a stack — dwelling with extended replacement cost and ordinance coverage, HO-5 contents, a managed hurricane deductible, flood, a current valuables schedule, an umbrella with verified attachment points, and workers’ comp if there’s staff. The failures happen at the seams between policies, which is why the stack needs to be reviewed as one system by one agent who can see all of it.

If your East End home is insured off a purchase price and a default form, it’s worth an hour to re-underwrite it properly — before storm season, not after. Call (718) 865-8458 or request a quote.
