How to Protect Your Home While It's Listed and Empty

Protect a vacant listing by locking down access with a coded lockbox and an alarm, shutting off or monitoring the water supply, keeping the lawn and utilities maintained, and visiting on a schedule you document. The order matters: access control and water first, because those two cause the fastest, most expensive damage.
Protecting a vacant listing means controlling who gets in, keeping water where it belongs, and making the house look occupied and cared for. Do those three things on a schedule and you avoid the expensive failures — burst supply lines, stripped copper, cancelled insurance, and a lawn that tells every buyer the seller stopped caring.
An empty house behaves differently from an occupied one. Nobody flushes a toilet, nobody notices a drip under the sink, nobody hears a window break. Everything that goes wrong in a vacant home goes wrong quietly, and by the time anyone sees it, the damage has had weeks to spread. The plan below is ordered by consequence, not by convenience.
Start With Access Control
Every vacant listing has an access problem: buyers, agents, inspectors, appraisers, cleaners, and contractors all need in, and each one is a chance for a key to be copied or a door to be left unlocked. Fix the system before you list, not after the first showing.
Use a coded lockbox with a unique code rather than a combination everyone shares, and change the code whenever a showing window closes or a contractor finishes. If your market uses a digital showing service, lean on it — it logs who entered and when, which matters enormously if something disappears. Skip the hide-a-key rock; they are the first thing anyone looks for.
Inside, an alarm system with glass-break and motion sensors is the single strongest deterrent you can install. Put a visible sign and window decals where a passerby can see them. Even in a quiet neighborhood, the difference between a house with signage and one without is significant, because most break-ins into vacant homes are opportunistic rather than targeted.
Also tighten the small things people forget: replace the strike plates on exterior doors with longer screws, check that every window latch actually engages, and lock the garage side door and any crawlspace or attic hatch. A house that looks difficult to enter gets skipped.
Shut Down or Watch the Water
Water is the most expensive thing that can happen to an empty house, and it is the most common. A supply line to an upstairs toilet or an ice maker can run for weeks before anyone opens the door. By then you are looking at soaked subfloor, swollen cabinets, and mold that has already colonized the drywall.
You have two reasonable strategies, and you should pick one deliberately.
- Full winterization or full shutoff. Turn the main supply off at the street or at the interior main valve, then open every faucet and hose bib to drain the lines. Add antifreeze to toilet bowls and sink traps if freezing is possible. This eliminates supply-line flooding entirely, at the cost of the house having no running water during showings.
- Keep water on but monitored. If showings need working plumbing, install a leak-detection sensor near the water heater, under every sink, and behind the washing machine, plus an automatic shutoff valve that closes the main when a sensor trips. Have someone walk the house weekly to look at ceilings, cabinet bases, and the water heater pan.
The water heater deserves its own check
An empty house draws almost no hot water, so a failing tank gives no warning — no lukewarm showers, no running out mid-shower. Look at the base of the tank for rust streaks and at the floor around it for staining. If the unit is past its expected service life, a proactive replacement is cheaper than a flood claim and a remediation crew.
While you are at it, clear the condensate drain line on the air conditioner. A blocked line in an empty house leaks into the ceiling and nobody notices until the paint bubbles.
Keep Utilities Running Enough to Prevent Damage
Sellers often cancel everything to save money, and that decision creates bigger problems than it solves. Electricity and gas should stay on in most cases, with the thermostat set to a moderate range year-round. In a hot climate, an unconditioned house turns into an oven: paint fails, caulk and grout crack, wood cabinets and doors dry out and shift, and adhesives let go. In a cold climate, the opposite happens and pipes burst.
Set the thermostat and leave it. Do not turn the system off entirely, and do not let a showing agent adjust it — a house that has been sitting at 95 degrees takes hours to recover before a showing, and buyers feel the heat the moment they step inside.
Keep the water heater on if you are keeping water on, since a cold tank in a cold house is a freeze risk. Keep exterior lighting on timers so the house is lit at dusk. If the home has a pool, spa, or water feature, the pump and filtration need to keep running — stagnant water grows algae fast, and a green pool reads as a neglected property no matter how good the interior is. Budget for these ongoing utility costs and treat them as part of selling the house, not as optional.
Make the House Look Lived In
A vacant house advertises its vacancy. Dark windows at night, mail stacking up, a flyer tube stuffed with old brochures, and an unmowed lawn all tell anyone watching that nobody is home. Reversing those signals is cheap and effective.
Arrange for mail to be forwarded or held, and stop delivery of newspapers and packages. Put interior lights on randomizing timers in two or three rooms rather than one, so the pattern does not repeat at the same time every night. Exterior lights on a dusk-to-dawn or timer schedule do most of the work.
Landscaping is the visible half of the problem. Mow on a schedule, edge the walks, pull weeds from the beds and driveway cracks, and trim shrubs away from windows and doors so nothing gives cover to someone at a window. If snow is part of your climate, have the driveway and walk cleared after every storm — an unshoveled drive is the clearest possible sign that no one is coming and going.
Inside, leave the house clean and uncluttered but not stripped bare. A few staged pieces, blinds set at the same height in every window, and a faint scent of clean rather than heavy air freshener all help. Take out the trash, run the disposal, and pour water down every drain so traps do not dry out and let sewer gas up into the house.
Handle Insurance Before You Need It
This is the step sellers skip, and it is the one that can cost them everything else. Many homeowner policies reduce coverage or exclude certain claims once a home has been vacant for a set number of days. If a pipe bursts in month three of an empty listing and the policy treats the home as vacant, the claim can be denied.
Call the insurer as soon as you know the house will be empty, tell them the actual timeline, and ask specifically what changes. You may need a vacancy or vacant-property endorsement, a higher deductible, or a policy that includes the kind of monitoring you have installed. Ask whether the insurer offers a discount for an alarm system and automatic water shutoff, and get whatever you agree to in writing.
Also confirm that liability coverage still applies to people who walk through during showings. If a buyer's agent slips on an icy walk or a stair rail gives way, you want that covered. Keep a written record of every maintenance visit, repair, and inspection — insurers ask for evidence of care after a loss, and a log is the easiest way to provide it.
Set a Visiting Schedule and Document It
Someone should physically walk the property on a regular cadence — weekly is a reasonable target for a vacant listing, and more often after a storm or a cold snap. A drive-by glance is not a visit. The person going in should open cabinets under sinks, look at ceilings for new stains, run water in every fixture, flush toilets, check the thermostat setting, test the alarm, and walk the exterior for broken windows, damaged trim, or signs someone has been around.
Write down what was checked and what was found, with dates. That log does three jobs: it catches small problems while they are still small, it satisfies an insurer after a claim, and it gives you a factual answer if a buyer asks how the house has been maintained. It also creates a paper trail if a contractor or showing agent damages something.
Between visits, use what you have. A monitored alarm, leak sensors tied to an automatic shutoff, and a couple of inexpensive cameras covering the front door, driveway, and rear entry give you eyes on the property without driving over. Check the camera feed after every showing window and after every contractor visit.
What to Do When Something Goes Wrong
Even with a good plan, things happen. What separates a nuisance from a disaster is how fast you respond and who you can call at 2 a.m.
- Water intrusion: shut off the main, remove standing water, and get drying equipment in within a day or two. Mold growth starts quickly, and the difference between a dried-out room and a gutted one is measured in hours.
- Break-in or vandalism: do not clean up before documenting. Photograph everything, file a police report, and notify the insurer before repairs begin.
- Storm damage: tarp or board up immediately to prevent further water entry, then file the claim. Documenting the initial damage matters more than a tidy-looking house.
- Theft of fixtures or copper: report it, then secure the openings. A house with an unsecured door or window will be entered again.
Line up your contacts before you need them — a plumber, a restoration company, a handyman, and a landscaper who will answer on short notice. Trying to find a plumber during an active leak is how a small repair becomes a large one.
A vacant listing is manageable, but it is not passive. It takes a lockbox system, a decision about water, utilities left on and set, a house that looks occupied, and a documented visiting routine.

Common questions
Should I turn off the water in an empty house that's for sale?
Turning the main supply off and draining the lines eliminates the most expensive risk in a vacant home, but it means no working plumbing during showings. If you need working water, keep it on but install leak sensors and an automatic shutoff valve, and have someone check the house weekly. Either approach is far better than leaving the water on with no monitoring.
Does homeowners insurance cover a vacant house?
Often not on a standard policy. Many policies reduce or exclude coverage once a home has been vacant for a certain number of days, so a burst pipe claim can be denied. Call your insurer as soon as you know the house will be empty, tell them the real timeline, and ask what endorsement or policy change is required.
How often should someone check a vacant listing?
Weekly is a reasonable baseline, with an extra visit after any storm, cold snap, or major contractor visit. The visit should include opening sink cabinets, checking ceilings for stains, running water in every fixture, flushing toilets, and walking the exterior. Keep a dated written log of what was checked.
How do I keep a vacant house from looking abandoned?
Forward or hold the mail, stop newspaper and package deliveries, and put interior lights on randomizing timers in two or three rooms instead of one. Keep the lawn mowed, weeds pulled, and shrubs trimmed back from windows, and clear snow promptly if your climate requires it. Those visible signs are what tell a passerby whether anyone is watching.
What's the biggest risk to an empty home on the market?
Water damage from a supply line or water heater failure, because it runs unnoticed for weeks and leads to structural damage and mold. Theft and vandalism are the second concern, and they're best addressed with a monitored alarm, visible signage, and controlled access through a coded lockbox.
