Entering a neighbour's home to fix a shared part of the building

Some repairs simply cannot be done from the stairwell. The building's main soil pipe runs through the bathroom on the third floor, the damp patch on the second-floor ceiling comes from a pipe in the flat above, the water supply crosses inside a kitchen. To reach that shared part of the building you have to go into a private home, and that is where many small communities get stuck.

The good news is that it almost always works out. The bad news is that, handled badly, a two-day job becomes months of tension between people who pass each other in the hallway every morning.

Why a neighbour has to let you in

The general principle in Spain is easy to grasp: the flat is private, but the building belongs to everyone. When a repair is needed to look after the building or its shared services, and there is no other reasonable way of doing it, the owner or tenant has to allow access.

In exchange, the community cannot walk in just because it feels like it: it has to give notice, explain what it is coming in for and cause as little disruption as possible. And if the work damages anything inside the home, such as chipped tiles or an opened-up false ceiling, the community is responsible for putting it back as it was.

Who pays for what

Sort this out on day one, because it is the biggest source of arguments:

• The repair of the shared element (the soil pipe, the main water pipe, the slab) is paid for by the community.
• The damage caused inside the home to reach that element is also down to the community: opening up, closing up and making good.
• Anything that is a fault of the flat itself (the waste pipe under their own basin) is paid for by the owner.
• Damage the leak has caused to furniture or belongings usually goes through insurance; report it early and let the insurers talk to each other.

Putting all this in writing before starting avoids the classic "nobody told me they were going to leave my bathroom like this".

How to ask properly

• Talk in person or by phone first. A cold written notice with no conversation behind it puts anyone on the defensive.
• Then send the notice in writing: what the fault is, why access through their home is needed, what will be touched, how long it should take and who is coming in (the name of the firm).
• Offer two or three alternative dates, including an early slot or a non-working day if the neighbour works away.
• Make it clear that the community will make good whatever is opened up and that the neighbour is not paying for the work.
• If the neighbour is a tenant, tell the owner too. A lot of refusals are simply fear of deciding something that is not theirs to decide.
• Keep the reply, whatever it says.

If they do not answer, or they refuse

First, rule out the obvious: plenty of people do not answer because they are away, because the notice sat in a letterbox nobody checks, or because the flat is rented and the message never reached the owner. Try another route and keep a record of each attempt.

If the refusal is clear, do not force anything and never go in without permission, however urgent the fault and however justified the annoyance. The sensible thing is to put in writing the attempts made, the damage building up meanwhile and the alternatives offered, and then take advice from a lawyer or the community's insurer, whose policy often includes legal advice. They will say what steps are available and in what timeframes, which is exactly the part you do not want to improvise.

How to keep it from ending badly

• Do not turn the repair into a public trial of your neighbour in the building's chat group. What gets written in the heat of the moment is remembered for years.
• Explain the work in detail: most of the fear comes from not knowing whether half the bathroom is coming down.
• Turn up on the day and time agreed. If the plumber is not going to make it, say so.
• When it is finished, go and see how it looks and close it off with the neighbour, not just the contractor.
• If a second visit is needed, say so before you leave.

Most of these conflicts do not come from bad faith, but from the feeling of having people walk into your home without an explanation. A clear notice, agreed dates and a promise to leave everything as it was solve nearly all of them.

And keep a record of everything: the notice, the dates offered, the neighbour's reply, photos before and after and the agreement on who pays for what. Having that story in one place everyone can look at, instead of in the memory of whoever happens to be president that year, is exactly what Dommiva is for on the day someone asks what was agreed.
