Before you buy · Mallorca

Checking a house before you buy on Mallorca,
building fabric, permits and renovation costs.

Before you buy a finca, a townhouse or an apartment on Mallorca, we look at the property as architects. We check the building fabric and permit status, for fincas also the rules for rustic land, and whether your plans are possible there at all. Before the notary appointment you also receive a first cost framework for the renovation. This is a technical and planning check and does not replace legal advice. Ownership, charges and the purchase contract are for your lawyer and the notary.

What the listing does not show

Does the building match the paperwork?

What buyers of a finca most often find out afterwards is that the building does not match its documents. Stables became bedrooms, a terrace was roofed over, an outbuilding appeared, and not all of it is recorded. That decides what you are allowed to renovate at all.

So bring a planner to the viewing before you are committed. We compare what is built with what is registered and licensed, and tell you clearly what the property allows, even if you do not like the answer. This conversation costs less before a purchase than after it.

Our check

Three things we check before you buy.

Each of these points can be clarified before you buy. Found out afterwards, it usually costs more.

i.

Building fabric

We look at the structure, roof and timbers, rising damp in walls without a damp-proof course, pipework and wiring. For fincas we add water, power and wastewater, which are often off-grid, and the access. Where a finding calls for it, we advise a more detailed investigation before you commit.

ii.

Permit status and planning rules

Does what is built match what is registered and licensed? Rustic land comes with tight limits, and a legal house on a plot below the minimum size cannot be extended. In Palma’s old town we read the building’s catalogue file.

Building permits and rustic land
iii.

Your plans and a first cost framework

We assess whether your plans can be carried out here and what they would cost. Most of our residential projects on Mallorca come to €1,200 to €2,500 per square metre, and in Palma a building permit adds 6.61 percent in tax and fee. Where your property sits in that range, we tell you after the viewing.

What a finca renovation costs
What we often find

Typical findings,
and what they mean.

Most findings are no reason to walk away. But they belong in your sums and your timeline before the notary appointment.

  • i.

    Extensions without a permit

    Many old fincas have them. Whether they can be legalised partly decides what you may renovate later. A house legalised this way may also not be let to tourists.

  • ii.

    Damp on the ground floor

    Rubble walls often sit on the ground without a damp-proof course. Signs of this are salt deposits in the plaster and timber giving way at floor level.

  • iii.

    Roof and timber structure

    Both are often in worse condition than a viewing suggests. We look at what is accessible and tell you openly where uncertainty remains.

  • iv.

    Rural utilities

    Well or cistern, solar power with storage, wastewater treated on the plot: this equipment costs real money and has to match the use you are planning.

  • v.

    An apartment in an older building

    In Palma every building needs a technical inspection at 50 years, then every ten years. The community’s report shows which works on shared parts are due and partly yours to pay. Ask for it before you buy.

  • vi.

    Plans for alterations or a terrace

    In an apartment, the owners’ meeting decides on work to the structure and façade and on enclosing a terrace. What you want to change after buying should fit with that.

Arabic Loft.

A loft in the heart of Palma, in a historic townhouse with ceilings almost five metres high. Stone walls, arches and ceiling beams shape the rooms. We designed the entire interior.

FAQ

Questions before you buy.

We check whether the built state matches the registered state and how additions are recorded. We also look at structure, roof, damp, water, power, wastewater and access. Finally we assess whether your plans are possible on this plot and give you a first cost framework.
No. We check, from a technical and planning point of view, whether the building suits your plans and what it would take. Ownership, charges and the purchase contract belong with your lawyer and the notary. Ideally both run in parallel and finish before the notary appointment.
They help decide what you may renovate or extend later. Unpermitted extensions cannot always be legalised, and when they can, it comes at a price: the extraordinary procedure under Law 7/2024 has been open since February 2025 for three years and costs 10, 12.5 or 15 percent of the construction cost depending on the year of application. A challenge against it is pending before the Constitutional Court.
Before you commit contractually, at the latest before the notary appointment, and ideally while you are still choosing between properties. Send us the listing, photos and any drawings, and we agree the approach in the Project Check.
A fraction of the purchase price. We agree scope and fee after the first conversation, depending on the property and how deep the check needs to go. The Project Check itself is without obligation.
Let's talk

Your home on Mallorca deserves this.

"Tell us about your property, your timeline, what you are hoping for. We will come to you, listen, and present a concept and a realistic cost estimate, before you commit to anything."
