Unoccupied home insurance in BC: the clause that voids water damage

What the clause actually says

Insurers do not ask you to be vaguely responsible. The condition is mechanical. It names a number of days, and then it names the ways out. Once a dwelling has been unoccupied beyond that number during the heating season, loss or damage caused by water escape, freezing or rupture is excluded, unless the owner has done one of the following:

Kept the heat on and arranged for a competent person to enter and check the home at a stated interval, usually daily or every three days, for the whole period.
Shut the water off at the main and drained the system, including the supply lines, the fixtures and often the appliances.
Fitted a monitored alarm that reports low temperature, and in many wordings water escape, to a monitoring station or to a device that is actually watched.

Those are not suggestions and they are not alternatives to reading your policy. They are the compliance options the wording gives you, and if you have taken none of them the insurer does not have to pay for the burst line.

Unoccupied and vacant are two different words in your policy, and only one of them is about a holiday.

Unoccupied is not the same as vacant

This trips up almost everyone, so it is worth being exact.

Unoccupied means the home is still furnished and you still intend to return, but nobody is living in it right now. A Kelowna house whose owners are in Calgary from November to April is unoccupied. This is the clause with the day counts below, and it mostly bites on water, freezing and escape of water.
Vacant means the furniture is gone, or you have moved out with no intention of coming back, or a newly bought home has never been moved into. Past roughly thirty days of vacancy most policies remove theft, vandalism, malicious damage and water entirely, not just narrow them. This is a much harsher clause, and it is generally not the one a seasonal owner is in.

If a home is genuinely vacant, that usually needs a specific vacancy permit endorsement from the insurer, arranged in advance and priced accordingly. If a home is merely unoccupied, you are in the day-count world below.

Trigger days, by insurer

The number varies a great deal, which is the part owners find surprising. Four days at one insurer, thirty at another, for the same house. The table below reflects wordings and public guidance available at the time of writing, and it is here to show you the shape of the problem, not to tell you what your own policy says.

Compiled from published insurer wordings and consumer guidance, August 2026. Insurers revise wordings, and brokers add endorsements that change all of this. Treat the table as a map of the terrain, then read your own policy, which is the only document that governs your claim.
Insurer	Trigger	Accepted ways to comply
Optimum	4 days	Heat maintained with checks, or water shut off and drained, or a monitored heating alarm
Wawanesa	4 days	Checks every 3 days, or water off and drained, or a monitored alarm
Portage Mutual	4 days	Daily checks by a competent person, or water off, or a monitored alarm
Aviva	8 days	Heat maintained, or water off and drained
SGI Canada	10 days	Daily checks, or water off, or electronic monitoring
Sandbox	10 days	Daily checks, or a monitored low-temperature alarm
Red River Mutual	14 days	Daily checks after day 14, or a monitored alarm, or drained

Intact	heating season	Water damage excluded where heat is intentionally off

How to find the clause in your own policy, in about four minutes

Open the PDF your broker sent at renewal. The one you have never opened. Search it for the words unoccupied, vacant and heating season.
Read the paragraph around each hit. You are looking for a number of consecutive days and a list of conditions joined by "unless".
Write down the number. That is your budget, in days, for leaving the house alone in winter.
Write down which of the three compliance options your wording accepts. Not all wordings accept all three.
Email your broker one sentence: "My home at [address] is unoccupied from [date] to [date]. Please confirm in writing what I need in place for water damage to remain covered." Keep the reply. That email is worth more at claim time than anything on this page.

If your broker asks for documented checks. Ask exactly what they want documented: the interval, whether photographs are required, and whether they need the record produced at claim time or on request. Then make sure whoever attends your home can actually produce that document. A neighbour with a key cannot. This is the single most common gap we see.

The honest comparison: an alarm versus a person

Look again at the right-hand column of the table. In most of those wordings, a monitored low-temperature alarm is full compliance on its own. A capable sensor kit is a few hundred dollars, once, and several insurers now hand them out free. If your only goal is to satisfy the clause, that is the cheapest correct answer and we will say so.

What a sensor cannot do is everything after the alert. It tells you the mechanical room is at 3 degrees while you are four provinces away. It does not close the main, get a plumber through a locked door before morning, move what is on the floor, or tell you whether the stain on the ceiling is old flashing or a live leak. That gap between knowing and it being handled is the entire reason this service exists.

So the sensible structure for an absentee owner is both, in that order: the alarm answers the insurer, and a person answers the alarm. That is how Brasskey is built. The monitored suite is installed and included in every tier rather than sold as an upsell, and a licensed builder is the one who drives over when it speaks.

A monitored alarm satisfies your insurer. It does not shut your water off at 2am.

What this costs to get wrong

A supply line that lets go behind a second-floor wall in January will run for as long as nobody is there. In a finished Okanagan custom home, that is routinely a six-figure restoration once you count the millwork, the flooring, the drywall, the mechanical and the months of it. The declined claim is not the worst part. The worst part is that the reason it was declined was a clause you agreed to and never read, and a fix that would have cost a few hundred dollars.

Questions owners ask us

Sometimes, and only if it is genuinely monitored. A thermostat that pushes a notification to a phone that is on airplane mode over the Pacific is not monitoring. Wordings that accept "electronic monitoring" usually mean a device reporting to a monitoring station or to a party who has undertaken to act on the alert. Ask your broker to confirm in writing that your specific device satisfies the condition, and keep the reply.

Shutting the main is not the same as draining the system. Most wordings that offer this option require both: the supply shut off and the lines and fixtures drained, sometimes including appliances and the hot water tank. Water sitting in a line behind a closed valve still freezes and still splits the pipe. If you go this route, have it done properly and record the date it was done.

Wordings rarely define it tightly, which cuts both ways. In practice an insurer is looking for someone who attended, who was capable of recognising a problem, and who can evidence both. A dated, timestamped, photographed record of each attendance is what turns an assertion into evidence. A neighbour who says they looked in most weeks is an assertion.

Yes, and it is in your interest. A material change in the risk that you did not disclose is a much worse conversation at claim time than a slightly higher premium or an endorsement now. Tell them the dates, ask what they require, and get the answer in writing.

No. Brasskey is an estate care company led by a licensed British Columbia residential builder, not an insurance broker or a law firm. Nothing here interprets your policy, and only the wording you actually hold governs your claim. What we can do is document a home to the standard a broker or an adjuster asks for, and speak to your broker directly about what they want on the record.
