Why a Vacant Home Is a Vulnerable Home

A house left empty for weeks or months faces risks that daily occupancy naturally prevents: slow leaks go undetected, pests find undisturbed entry points, and an unchanging exterior signals to opportunistic thieves that no one is home. According to the Insurance Information Institute, water damage and freezing are among the most common and costly homeowner insurance claims — risks that multiply when a property sits unoccupied.

Whether you are heading out for an extended vacation, a work assignment, or a season at another residence, the preparation steps below are organized to work through room by room and system by system. Complete them in the days before departure, not the morning you leave. If you are also preparing a vehicle for a long drive ahead of the trip, the pre-trip vehicle safety checklist covers that ground separately.

Vacancy Clauses Can Limit Your Insurance Coverage

Most standard homeowner insurance policies reduce or exclude certain coverages once a property has been vacant for 30 to 60 consecutive days. Damage from vandalism, water, and liability may be affected. Contact your insurance carrier before you leave to understand your policy's specific vacancy provisions and ask about a vacancy endorsement if your absence will be extended.

Tools and Resources You'll Need

Most of what you need is already in your home. Gather the items below before you start so you are not scrambling at the last minute.

Required

Water shutoff wrench or handle

Required to turn off the main water supply valve, which is often stiff or located in a crawlspace.

Required

Smart plug or lamp timer

Programs interior lights to switch on and off on varied schedules, maintaining an occupied appearance.

Optional

Battery-powered water leak detector

Placed near water heaters, washing machine connections, and under sinks to alert your emergency contact of any moisture.

Optional

Desiccant dehumidifier or electric dehumidifier

Controls humidity in basements and enclosed spaces to prevent mold growth during an unoccupied period.

Optional

Home security app or monitoring service

Enables remote visibility and alerts through connected cameras or a monitored alarm system.

Optional

Surge protector power strips

Protects electronics that must stay plugged in from voltage spikes while unattended.

The Full Preparation Checklist

Work through each group methodically. Mark items complete as you go so nothing is accidentally skipped. For a broader look at year-round home care, the seasonal home maintenance checklist provides a useful ongoing framework to pair with this departure routine.

Water and Plumbing

Shut off the main water supply valve to eliminate the risk of a burst pipe or slow leak flooding the home. Must
Drain faucets and flush toilets after shutoff to relieve residual pressure in the lines. Should
Pour a small amount of mineral oil into toilet bowls and rarely used drains to slow evaporation of the water seal and block sewer gas entry. Nice to have
Turn the water heater to its vacation or pilot setting to reduce energy use without allowing the tank to sit cold. Should

Heating, Cooling, and Air Quality

Set the thermostat no lower than 55°F in winter to prevent pipe freezing, or no higher than 85°F in summer to limit humidity buildup. Must
Replace HVAC filters before departure so the system runs cleanly on its reduced schedule. Should
Place moisture-absorbing products (such as desiccant packs or a dehumidifier set to run automatically) in basements and crawlspaces prone to dampness. Should
Check that exhaust fans in bathrooms and kitchens are clear of obstructions to discourage mold growth. Nice to have

Security and Access

Lock and physically test every exterior door, window, and sliding door before leaving. Must
Notify your home security or alarm monitoring company of your departure dates and provide an emergency contact. Must
Set interior lights on random-interval timers or smart plugs so the home does not appear uniformly dark. Should
Pause mail and package delivery through USPS Hold Mail and any regular delivery subscriptions to avoid accumulation at the door. Must
Arrange for lawn mowing or snow removal as appropriate for the season, so the exterior looks maintained. Should

Electrical and Appliances

Unplug non-essential electronics and appliances to eliminate phantom loads and reduce fire risk from power surges. Must
Test smoke and carbon monoxide detectors and replace any batteries showing a low indicator. Must
Empty, clean, and leave the refrigerator door slightly ajar if you plan to turn it off for an extended stay, or keep it running at its normal setting for shorter absences. Should
Confirm the stove, oven, and dryer are fully off — not just on standby — before departure. Must

Pests and Exterior

Seal visible gaps around pipe entry points, dryer vents, and foundation cracks with caulk or steel wool to discourage pest entry. Should
Remove all perishable food from counters, pantries, and the refrigerator, and take out all trash before leaving. Must
Cut back any tree branches or shrubs that touch the house, reducing both pest access and storm damage risk. Nice to have

If your home already has any unresolved issues — water stains, flickering circuits, foundation concerns — address them before you leave. The warning signs that need immediate attention article outlines which problems should never be deferred, especially before a long absence.

Never Leave Without a Local Emergency Contact

A checklist alone cannot respond to a burst pipe at 2 a.m. Identify a specific person — a neighbor, family member, or paid property-check service — who has a key, knows the utility shutoff locations, and is willing to act on your behalf. Provide them with contact numbers for a local plumber, HVAC technician, and your insurance carrier. This single step can be the difference between a minor incident and a catastrophic loss.

Arranging a Trusted Point of Contact

No checklist replaces a human set of eyes. Arrange for a trusted neighbor, friend, or professional property-check service to visit at least once a week. Give them a spare key, your emergency contact number, and the name of a local plumber and HVAC technician in case something fails. Leave a written note inside with utility shutoff locations — the water main, electrical panel, and gas shutoff — so they can act quickly if needed.

Notify your homeowner's insurance carrier of the extended vacancy before you leave. Many policies include clauses that limit or exclude coverage for damage that occurs after a property has been unoccupied beyond a defined period (often 30 or 60 days). Your agent can clarify your specific policy terms and suggest a vacancy endorsement if needed. This is general information — consult your insurance professional for advice specific to your policy and situation.
