Second homes that sit empty for months: the unoccupancy clause that voids your cover

Part of our complete guide to holiday-home & short-term rental insurance in Portugal — read the pillar for landlord liability, unoccupancy and villa cover.

A second home in Portugal often sits quiet between family visits, winter closures or rental seasons. That is exactly when small problems become large claims: a burst pipe runs for days, a storm breaks a shutter, or a burglary is discovered long after it happened.

Many owners only discover the unoccupancy condition when they claim. The policy may say the home cannot be left unoccupied beyond a certain number of consecutive days, or that theft, escape of water and malicious damage are restricted after that period.

What the clause actually says

The wording varies by insurer, but the architecture is consistent. The policy defines a property as unoccupied — desabitada or não habitada permanentemente — after a stated period without being lived in, commonly 30, 60 or 90 consecutive days. Once that threshold is passed:

• Theft cover is typically suspended entirely. Not reduced — suspended.
• Water damage is restricted or excluded, on the reasoning that a leak in an occupied house is noticed in minutes and in an empty one in months.
• Glass breakage and malicious damage may also fall away.
• The fire and lightning base normally continues, as does liability.

Read that list again. The policy stops covering the two most likely events and continues covering the least likely one, at precisely the point when nobody is there to notice a problem developing. That is not an insurer being unreasonable; it is a rational response to a genuinely different risk. But it is the opposite of what most owners assume they have bought.

Who this catches

• Second-home owners who visit at Easter and in August and leave the property empty from September to March.
• Owners who have listed a property for sale and moved out.
• Anyone whose property is empty during a renovation — a case many retail insurers exclude outright rather than merely restrict.
• Owners between long-term tenants for more than a couple of months.
• People who spend the winter in their home country and treat the Portuguese property as the second one for half the year.

That last group is the largest and the least aware, because they think of the Portuguese house as their home. The policy thinks in consecutive days of occupation.

Why insurers care about empty months

• No one notices leaks, electrical faults, forced entry or storm damage quickly.
• Gardens, pools and terraces can signal that the home is unattended.
• Security systems may be switched off, unmonitored or without maintenance logs.
• Water, gas and electricity may remain connected during long absences.

What to check before you leave

Ask for the exact number of days allowed, whether the count resets after a short visit, and what proof the insurer expects if there is a claim. A neighbour checking the post is useful, but it may not satisfy the policy if it requires documented inspections.

How to make the cover work

• Declare realistic occupancy, including winter closures and gaps between guests.
• Keep records of property checks, alarm maintenance, pool visits and keyholders.
• Confirm whether water must be turned off during long absences.
• Review sums insured for contents that remain in the property year-round.

The point is not to make the home look occupied. It is to make the insurance wording match how the home is actually used.

A worked example

An apartment in Tavira, owned by a family in the Netherlands, was used at Easter and for three weeks in August. Between those visits nobody attended it. In February a supply pipe to the washing machine failed. The water ran, by the insurer’s estimate, for most of a week, and reached the apartment below.

The policy suspended water-damage cover after 90 consecutive days of unoccupancy. The gap between the August departure and the February discovery was 148 days. The neighbour’s damage was paid, because third parties are protected; roughly €14,000 of the owner’s own damage was not. Written correctly as a seasonal property with a key-holder, the same policy would have cost about €45 a year more.

Finding your own number

The clause is on the condições particulares, usually under desabitação or as a condition attached to the theft and water sections. It states a number of consecutive days — most commonly 30, 60 or 90 — after which specified cover is suspended or restricted. Three things worth knowing about that number: it counts consecutive days, so a single visit resets it; it is a condition rather than an exclusion, which means it can usually be varied; and the insurer will establish the date of the last visit from flight records, utility consumption and key-holder logs if a claim depends on it.

What the insurer asks at underwriting

• How many weeks a year the property is occupied, and in which months.
• The longest continuous period it stands empty.
• Whether a key-holder, neighbour or management company attends, and how often.
• Whether there is an alarm, whether it is monitored, and whether it is actually armed when you leave.
• Whether the water supply is turned off at the mains between visits.
• Whether the property is let at any point — which changes the analysis entirely.

The three mistakes we see repeatedly

• Insuring a second home as a permanent residence. It is the single most common error in the Algarve second-home market, and it removes cover for the two perils most likely to occur while you are away.
• Not naming a key-holder. Most insurers will extend or remove the restriction where somebody can attend. It is the cheapest fix available.
• Leaving the water on. A closed stopcock costs nothing and eliminates most of the exposure the clause exists to price.

What to do

Find the number on your schedule, count the days between your visits, and if the second figure is larger than the first, send us the policy. If the property is also let at any point in the year, the analysis changes again — that is covered in our guide to holiday-home and short-term rental insurance in Portugal.

What it costs to close the gap

Writing a property correctly as a seasonal second home rather than a permanent residence usually adds €30 to €80 a year on an apartment and €60 to €150 on a villa. Extending or removing the unoccupancy restriction, where the insurer will do it, is often free once a key-holder is named and an alarm is in place; where it carries a loading, it is typically under €100.

Compare that with the exposure. The two perils the clause suspends — theft and escape of water — are the two most likely to occur in an empty property and the two most expensive when they run undetected. A leak found in week one is a plumber’s bill. The same leak found in month five is a rebuild of the ground floor and a claim from the neighbour below.
