Updated August 3, 2026. Quick answer: a house that sits empty for months is a different risk from one lived in year-round, and policies commonly say so. The two gaps that catch people are a vacancy or unoccupancy clause that can suspend cover after a stated period, and water damage from freezing excluded unless the property was prepared or monitored.
Vacant is not the same as unoccupied
Insurers commonly distinguish them, and the distinction decides claims. Unoccupied generally means nobody is living there but the contents remain. Vacant generally means empty of people and belongings. Policies frequently treat vacancy far more harshly, and many suspend or restrict cover once a stated number of consecutive days has passed.
A seasonal cabin can drift into the definition without anyone deciding anything. Nobody sets out to leave a property vacant; a season simply ends and the clock runs.
The freezing exclusion
Water damage from burst pipes is one of the commonest large claims on a seasonal property, and it is the one most likely to be excluded. Policies commonly require, during the period the dwelling is unoccupied, either that the heat be maintained or that the water supply be shut off and the system drained.
Read your own wording on this before the first cold season, and do what it says rather than what seems sensible. “I left the heat on low” is not the same as the policy’s requirement if the policy asked for the system to be drained.
The other gaps worth checking
- Flood is excluded, as always. Waterfront property is exactly where this bites — and a new flood policy normally takes 30 days, so it cannot be bought when a storm is forecast.
- Letting it out changes the risk class. Even occasional paid use can move the property outside a standard policy. Tell the insurer; discovering it at claim time is worse than the higher premium.
- Family use is not always covered as you expect — check who counts as an insured when relatives use it alone.
- Ownership changes break things. If the property has moved into an entity for succession reasons, the policy does not follow the deed automatically.
- Rebuild cost is higher in remote places. Materials and labour cost more where access is hard, and a limit set from a mainland estimate can be well short.
What to do before the season ends
- Find the vacancy or unoccupancy clause and note the day count.
- Do exactly what the freezing condition requires, and keep evidence you did it.
- Tell the insurer how the property is actually used — months empty, occasional family use, any paid use.
- Check the dwelling limit against a current local rebuild estimate.
- Ask what monitoring they will accept — a temperature or leak sensor sometimes satisfies a condition and sometimes earns a discount.
