Renovating a house you don't live in changes five practical things, and insurance is the one that can ruin you. Standard homeowner policies restrict or void coverage when a property sits unoccupied past 30–60 days — renovation on top of vacancy usually needs a vacant-dwelling or builder's risk policy, arranged before work starts. The rest is discipline: a written access list and key protocol, one local person doing a weekly walk-through who isn't the contractor, deliveries timed to installation so materials don't sit in an empty house, utilities kept on (and heat kept above 12°C / 55°F in winter), and neighbors treated as infrastructure — they are the ones who will call you about water under the door.
Tell your insurer before work starts
Most homeowner policies carry a vacancy or unoccupancy clause: if the property is empty beyond a stated period — commonly 30 or 60 consecutive days — coverage for vandalism, water damage, glass breakage, and sometimes theft is reduced or void. A renovation makes it worse, because many policies also exclude damage arising from construction unless the insurer was notified. An absent owner who starts a renovation without telling the insurer can end up uncovered on both counts at once.
The fixes, in ascending order of project size: a vacancy permit or endorsement added to the existing policy (small cosmetic projects), a vacant-dwelling policy (unoccupied property, modest works), or builder's risk coverage (structural work, additions, anything opening the envelope). Ask the contractor for their certificate of insurance as well — their general liability covers damage they cause, but it does not cover your building against a storm, a freeze, or a thief while it stands empty.
The one-line rule Notify your insurer in writing before demolition starts, and get the response in writing. An email thread costs nothing; a denied six-figure water claim costs everything.
Access without you there
Someone has to open the door dozens of times over a renovation — trades, deliveries, inspectors, the person doing your weekly check. Decide the mechanism deliberately. A coded lockbox is the norm and works fine if you change the code between contractors. A smart lock is better where there's connectivity: per-person codes, an entry log, and remote revocation the day the project ends.
Keep a written access list: every person and company with a code or key, added and removed by date.
Give the general contractor one code, not one per subcontractor — their subs are their responsibility.
Change all codes at substantial completion. It's a 10-minute task that closes the project's single biggest lingering exposure.
If there's an alarm, create a temporary contractor profile rather than handing over your own code.
Eyes on the ground that are not the contractor
The contractor sends you photos of their own work. That is useful and you should require it — daily during active phases — but it is not verification. An empty house needs one local person who walks the property weekly and reports to you, not to the contractor: a trusted neighbor, a paid property checker, a property manager, or a friend with a spare hour. Their job is small and specific — is the site locked, is anything sitting in water, does the work visible to a layperson match what the contractor said happened this week.
Keep the two streams separate. When the contractor knows an independent pair of eyes visits weekly, reporting discipline improves on its own. And when something looks off, you hear it from someone with no stake in the answer.
Job-site security in an empty house
Renovation sites get robbed for materials, tools, and appliances — copper pipe, wire spools, boxed fixtures waiting for install. An occupied house has natural deterrence; an empty one advertises itself: a skip outside, no car in the drive, no lights at night. Three cheap countermeasures do most of the work. Time deliveries to installation, so appliances and fixtures arrive the week they go in rather than sitting boxed for a month. Put interior lights on randomized timers and leave one camera facing the main entry — a €60 camera that texts you on motion is enough. And ask the contractor to lock tools in a jobsite box rather than leaving them spread out, which most will do unprompted for their own sake.
Utilities and the boring logistics
Power and water stay on — trades need both, and shutting water off entirely between work phases is only right for winter gaps with no heating. In heating season, keep the thermostat at 12°C / 55°F minimum so pipes, plaster, and new joinery survive. Forward the mail; an overflowing letterbox is both a vacancy signal and how you miss a permit notice. Arrange grass cutting or snow clearing in long gaps for the same reason. None of this is renovation work, and all of it lands on the absent owner unless it's explicitly assigned.
Neighbors are infrastructure
For a house you don't live in, the neighbors are your smoke detector, your leak sensor, and your security system, whether or not you've asked them to be. Renovations strain exactly that relationship: noise, dust, parked vans, a skip blocking the lane. Get ahead of it. Tell the adjacent neighbors before work starts — dates, what's being done, your phone number, and the contractor's. Ask the contractor to keep the street clean and the radio reasonable. A neighbor who was warned and given a direct line calls you about the small thing at week two; a neighbor who wasn't calls the town hall about the skip at week six.
Frequently asked
Does homeowner insurance cover a house that sits empty during renovation?
Often not fully. Most policies limit or void parts of the coverage after 30–60 consecutive days of vacancy, and many exclude construction-related damage unless the insurer was notified. Before work starts, ask your insurer in writing whether you need a vacancy endorsement, a vacant-dwelling policy, or builder's risk coverage, and keep the answer.
How often should someone physically check the house?
Weekly during active work, and after any storm or freeze event. The check is 15 minutes: locked, dry, heated, and the visible work roughly matches what was reported. During long idle stretches between phases, every two weeks is acceptable if remote sensors cover water and temperature.
Should the contractor be the one doing the weekly check?
No. The contractor documents their own work — require that too — but the weekly walk-through should be someone independent: a neighbor, a paid checker, or a property manager. Verification and reporting are different jobs, and the difference matters most exactly when something has gone wrong.
Do I need to be on site at any point?
For most projects, three moments justify presence: the scoping visit before contracts, a mid-project walk when the walls are still open, and the final punch-list walk. Everything else — decisions, payments, progress review — works remotely if photo discipline and a decision log are in place from day one.
