Why buyers get caught out
An attractive finca is often several buildings from different decades. If the guest house or the pool was never licensed, the buyer inherits the risk, the limits on renovation and the problems with insurance, finance and resale. Price and contract should reflect that before signing, not after.
What we review
- Land classification and category under the municipal plan and the island plan.
- Licences for the original house and every later extension, pool, annex and terrace.
- Infringement proceedings and whether enforcement has expired.
- Habitability certificates and legal residential use.
- Coastal law, natural areas, heritage catalogues and roads.
- Access, wells, water rights, septic systems and boundaries, with an architect.
Rustic land on each island
| Island | Main instrument | Typical issue |
|---|---|---|
| Mallorca | Mallorca Territorial Plan and municipal plans | Unlicensed annexes, Tramuntana protection |
| Menorca | Menorca Territorial Plan | Very limited extension rights |
| Ibiza | Ibiza Territorial Plan | Villas extended over decades, water supply |
| Formentera | Formentera Territorial Plan | Minimal new construction, strict tourism limits |
Legalisation
A building that complies with today's rules can be legalised with a licence after the fact. One that does not comply may still be safe from demolition once the enforcement period has expired, except on protected land, but it remains "out of planning" with limited works permitted. The extraordinary procedure created by Decree-law 3/2024 and Law 7/2024 can help some rural buildings where enforcement has expired, within a three-year window that each island council or municipality opens separately. We assess which route applies and what it costs.
Renovation and building projects
Before you buy a property to renovate, we check with an architect what the licence will allow: extensions, new openings, pools, change of use or works on a listed building. For plots, we confirm buildability and the conditions to obtain a licence. Read our guides to rural property in Mallorca, rural fincas in Ibiza and Sóller and the Tramuntana.
Working with architects
Planning questions are legal and technical at the same time. We work with independent architects and surveyors on every island and combine their findings with ours in one report. We are part of the Castell group in Palma; for other legal matters in English, see Castell.law.
Before you pay a deposit, ask a lawyer
Send us the listing or the document you have been asked to sign. An English-speaking property lawyer will tell you what needs checking and what it could cost you not to.
Questions about planning and rural property
Can I buy a villa with an unlicensed pool?
Yes, but you should know whether it can be legalised, whether the authorities can still act and how it affects value, finance and rental.
How long before an illegal building is safe in the Balearics?
Under the Balearic planning law the general period is eight years, but it does not run on protected rustic land and some special zones.
Can I build a new house on rustic land?
Only exceptionally, in some categories and with large minimum plots. On protected land, generally no.
Do you handle legalisation applications?
Yes, together with the architect who prepares the technical documentation.
