This is general guidance, not a reading of your policy. Wind deductibles, vacancy clauses, and endorsement availability vary by carrier and by property. Read your own policy and talk to your agent.
Plenty of off-Cape owners assume their homeowners policy follows them home: that the house in Wellfleet or Chatham stays insured the same way whether they're sitting in it or not. That isn't always true. Standard homeowners forms contain conditions that change what's covered once a house sits empty, and they contain a separate rule about frozen pipes that applies whether you've been gone a week or a season.
This isn't a scare piece. It's the conversation more second-home owners should have with their broker before they close up, because the fixes are mostly procedural.
The 60-day vacancy rule in the standard HO-3 form
Pull out your policy and look for the words "vacant" and "unoccupied." The widely used ISO Homeowners 3 Special Form (HO 00 03 05 11) is a useful reference point. In that form, two specific coverages stop applying to the residence premises if the dwelling has been vacant for more than 60 consecutive days immediately before the loss:
- Vandalism and malicious mischief, and any ensuing loss caused by the vandalism
- Glass or safety glazing breakage
The form also says a dwelling being constructed is not considered vacant (ISO HO 00 03 05 11, filed copy at maine.gov).
Two things matter here. First, the clock is consecutive days, so how your carrier treats a brief visit matters; ask. Second, your carrier may use its own form or Massachusetts-specific endorsements with different wording, triggers, or perils. Only your own policy's language controls.
"Vacant" vs "Unoccupied": read the actual word
These two words are not always interchangeable in an insurance contract, and the difference can decide a claim.
- Unoccupied generally means no one is living there, but personal property is still inside. Furniture, dishes, clothes in drawers. A closed Truro cottage in January is typically unoccupied.
- Vacant generally means the dwelling is empty of both people and the property needed to live there. A house mid-renovation between owners may be vacant.
Many owners hear "vacancy clause" and assume it can't apply because the house is still full of stuff. That's only safe if your policy's clause uses the word vacant and defines it that way. If a condition in your policy is written around unoccupied, it can apply to a closed-up, furnished house. Read the actual word, and read the definition if there is one.

The frozen-pipe rule that has nothing to do with vacancy
Separate from any vacancy clause, the HO-3 form excludes damage caused by freezing of a plumbing, heating, air conditioning or sprinkler system or household appliance, unless you used reasonable care to:
- Maintain heat in the building, or
- Shut off the water supply and drain all systems and appliances of water
(ISO HO 00 03 05 11). If the building has an automatic fire sprinkler system, the form requires you to keep the water supply on and maintain heat for coverage to apply.
That means a house with water in the lines and the heat turned too low, or a boiler that quits, is exactly the scenario this exclusion is written for. The Massachusetts Division of Insurance recommends that a house unoccupied at times during winter with hot water heat keep the thermostat no lower than 60 degrees, add a low-heat alarm, add a low-oil alarm if oil-heated, and be checked once a week (mass.gov/info-details/understanding-home-insurance). For a house not occupied at all during the winter, the DOI recommends shutting off the water service in the street, draining all water and heating lines, fixtures, boilers and water heaters, shutting off gas at the meter, and having the house checked weekly (mass.gov DOI).
If you're going the drain-down route, common among Outer Cape owners who shut down completely for winter, keep documentation. A dated plumber's invoice for the drain-down is the kind of record that helps at claim time. Get a written quote for the drain-down and for the spring re-pressurization.
Wind and flood: separate deductibles, separate policies
If your house is near the coast, check whether your policy carries a separate wind or named-storm deductible. The Massachusetts Division of Insurance says these deductibles are usually a percentage of the home's value, generally ranging from 1% to 5%, and can also be a fixed dollar amount (mass.gov DOI hurricane advisory). On a percentage deductible, the math gets large fast, so know your number before nor'easter season. Ask too whether it applies per event, per season, or per calendar year (mass.gov DOI).
Also ask how your policy settles roof claims (replacement cost or actual cash value) and whether roof age affects that. Carriers differ.
Flood is a separate problem. The DOI notes that flood damage is not included in a standard home insurance policy (mass.gov DOI), and the National Flood Insurance Program says water damage from burst pipes isn't covered by NFIP flood insurance, though it may be covered under a homeowners policy (agents.floodsmart.gov). Flood and freeze are separate problems with separate paperwork.
What to actually do before you close up
The fix isn't expensive; it's procedural.
- Call your broker in early October and ask: Do I have a vacancy or unoccupancy condition, and what's the trigger? What do I need to do to keep freeze coverage? Do I need to notify you when I leave?
- Install a freeze-monitoring sensor that alerts you when the interior temperature drops. The DOI specifically recommends a low-heat alarm for unoccupied homes with hot water heat (mass.gov DOI). Ask your carrier whether it requires or credits monitoring.
- If you'll be away for an extended stretch, price the vacancy or unoccupancy endorsement. Compare its cost to the gap it closes.
- Document the drain-down or the heat-on. Keep the plumber's invoice, alarm records, and dated photos of the thermostat and shut-off valves.
- Have someone check the house weekly, as the DOI recommends (mass.gov DOI). Keep the caretaker's visit log. Ask your carrier whether any inspection requirement applies to your policy.
Two don't-miss warnings
Don't assume short-term winter rental bookings keep the house "occupied." How a carrier treats rentals for occupancy purposes is a policy-specific question, and many homeowners policies restrict or exclude rental activity. If you rent short-term in winter, ask your agent whether you need a rental endorsement or a different policy type before you take the booking.
Don't let your policy be switched to a basic dwelling form without understanding what you're giving up. Dwelling fire policies come in different forms, and the basic ones cover fewer, named perils than an HO-3. That can be a legitimate product for a genuinely vacant house, but for a closed-but-furnished second home it may be a meaningful downgrade. Ask explicitly which form you're being moved to, which perils it covers, and why.
The carriers aren't trying to trick anyone, but the boilerplate doesn't tell you what it means for your house in February. A short call with your broker in early October, a freeze sensor, and a weekly check are the difference between a covered winter and a denied claim.

Frequently asked questions
Does homeowners insurance cover a house left empty all winter?
Not always in full. The standard HO-3 form stops covering vandalism and glass breakage once a home has been vacant for more than a set number of consecutive days, and your carrier may use different wording or triggers. Call your broker before you close up to understand exactly what your policy requires.
Will homeowners insurance pay for burst pipes if no one is home?
The standard HO-3 form excludes freeze damage unless you either kept the heat on or shut off the water and drained all systems. The Massachusetts DOI recommends a minimum thermostat level for homes unoccupied in winter, a low-heat alarm, and weekly checks — confirm the exact requirements with your own carrier.
What's the difference between vacant and unoccupied on a homeowners policy?
Unoccupied generally means no one is living there but personal property remains inside, while vacant typically means the home is empty of both people and the belongings needed to live there. The distinction matters because some policy conditions are written around "unoccupied," meaning a furnished but closed-up seasonal home can still trigger them.
Do I have a separate deductible for storm or hurricane damage on a coastal house?
Many coastal policies carry a separate wind or named-storm deductible calculated as a percentage of the home's value rather than a flat dollar amount, which can make it much larger than a standard deductible. Ask your carrier how yours is calculated and whether it applies per storm event or per calendar year.
Does renting my house out in winter count as it being occupied for insurance?
Not necessarily — how a carrier treats short-term rentals for occupancy purposes is policy-specific, and many homeowners policies restrict or exclude rental activity altogether. Ask your agent whether you need a rental endorsement or a different policy type before taking any winter bookings.
