Strip-out in an apartment building: community of owners rules

What does the law say about works in a community building?

Most apartment buildings on the Costa del Sol are under propiedad horizontal, regulated by the Ley 49/1960 de Propiedad Horizontal. For a strip-out two rules from it matter most:

• before demolishing walls, structure or façade elements in the building, the community must be informed;
• works that affect common elements need the agreement of the owners' meeting (junta de propietarios).

The law gives the community a voice because a demolition inside one flat can affect everyone else: the structure, the shared pipes, the façade and the peace of the building. This is a separate track from the town hall procedure; a valid declaración responsable does not replace the community's agreement, and vice versa.

Private element or common element?

Your flat is the private element. The building's structure, façade, roof, shared installations, stairs, lift and entrance are common elements. The tricky part is everything in between. As a working guide:

If in doubt, ask the administrator in writing whether an element is common. The answer protects you if a neighbour later complains.

Who to contact and what to send

In practice the community acts through its president and, in most buildings, a professional administrator (administrador de fincas). Sending them a clear written notice usually avoids most problems. Include:

1. the flat number and the owner's contact details, plus a local contact if you live abroad;
2. a short description of the work: what will be removed and what will not be touched;
3. the planned start date and expected duration;
4. how rubble will leave the building and whether a skip or a chute is needed;
5. how common areas will be protected and cleaned;
6. the contractor's name and phone number for day-to-day questions.

If the job touches structure or common elements, the administrator will tell you when the next meeting is and what it needs: usually the técnico's documentation. Plan for that timing; it is often the slowest part of the whole project.

Protecting the lift, stairs and entrance

The common areas are where a strip-out becomes visible to everyone. On our interior demolition jobs in community buildings we organise the route before the first bag is filled:

• Lift: walls and floor of the cabin lined with protective boards, and agreed limits on load and times of use. Some communities do not allow rubble in the lift at all; then the stairs or an external solution are used.
• Stairs and landings: floor protection on the route, corner guards on walls and door frames.
• Entrance and doors: protection of the portal floor and of the main door, which takes most of the knocks.
• Cleaning: common areas cleaned at the end of every working day, not only at the end of the job.

Where the lift cannot be used, our guide on getting rubble out of an apartment without a lift covers the alternatives.

Noise, dust and working times

Neighbours tolerate noise much better when they know when it will happen. Allowed working hours depend on the municipal rules and on the community's own internal rules (to be verified for each building), so ask the administrator what applies before agreeing the programme.

Within those limits we plan the loud tasks – breaking tiles off screed, cutting, chasing walls – in concentrated blocks, and leave quieter tasks such as bagging, sorting and removing false ceilings for the edges of the day. Dust stays inside the flat with sealed doors and plastic screens, and the front door is kept closed. The details are in our guide on noise, dust and working hours.

Shared pipes, ducts and hidden asbestos

Kitchen and bathroom strip-outs often expose the building's shared installations: soil stacks, rainwater downpipes and supply risers running through a duct (patinillo). These are common installations and should not be cut or rerouted without the community's agreement.

In older buildings some of these downpipes and ducts are made of fibre cement, which may contain asbestos. If a suspect pipe appears, work on it stops: removal of asbestos-containing materials can only be done by a RERA-registered company under an approved work plan. That work is carried out by a RERA-registered company working as our subcontractor while we coordinate the rest of the strip-out. Our sister site explains asbestos removal in communities of owners, and our guide on hidden asbestos in interior renovations shows where it tends to appear.

Managing it from abroad

Many owners we work with live in the UK, Scandinavia or elsewhere and visit their flat a few times a year. A strip-out can still run smoothly if three things are settled before work starts:

• Keys and access: who opens the flat on day one and who holds keys for the duration, including the portal and any garage access for loading.
• One local contact for the community: the administrator should know whom to call if a neighbour raises something. That can be you by phone, your técnico or us for site matters.
• Photo updates: regular photos of progress, of the common areas and of the protection in place, so that you see what the neighbours see.

For identification in the municipal and tax procedures for the works, the owner uses their DNI, NIE or NIF. You can write to us in English throughout the job.

Where friction usually starts – and how to avoid it

Most community disputes during a strip-out have little to do with law and a lot to do with surprises. The same few triggers come up again and again:

• The first knock without warning. A neighbour who hears breakers at the start of the day without any prior notice will call the administrator before lunch. A note in the portal and a message from the administrator a few days ahead prevents most of this.
• Dust in the stairwell. Even a little dust on the landing looks worse than it is. Daily cleaning of the route matters more than any letter.
• Blocked lift or entrance. Loading rubble during the busiest times of the day irritates everyone; agreed loading windows solve it.
• Parking and the skip. A skip that blocks a garage door or appears without a public road permit is a frequent source of complaints, and it is easily avoided by agreeing the skip position with the administrator in advance.
• Water or cracks in the flat below. Floor removal can reveal old leaks or move loose finishes. Isolating water before stripping a bathroom and checking the ceiling of the flat below with its owner before the job, if they agree, avoids arguments later about what was already there.

Photographing the common areas and, where possible, the neighbouring ceilings before work starts is cheap insurance. The photos protect everyone, including the neighbours.

A checklist before the first day

Use this list before you confirm a start date for a kitchen or bathroom strip-out or a full flat strip-out:

1. Community informed in writing; meeting agreement obtained if structure, façade or shared installations are affected.
2. Town hall procedure confirmed by your técnico (declaración responsable or licence).
3. Permit for any skip or scaffolding on the public road.
4. Lift rules and rubble route agreed with the administrator.
5. Working times agreed and shared with neighbours via the administrator.
6. Water, gas and electricity isolated in the areas to be stripped by your installer.
7. Any load-bearing wall work designed by your architect or engineer; see our wall removal page for how we execute it.

When several companies work in the flat at the same time, health and safety rules also come into play: the promotor appoints a safety coordinator during execution. Your técnico will advise whether that applies to your project.
