Once the title is clean, the real question is what the council will let you rebuild. Land status, the building licence, the 10% VAT on works and the paperwork needed to switch on water and power.
Our guide to abandoned Spanish villages and ruins explains what is for sale and why unresolved inheritance blocks so many deals. Here is the next stage: once the title is clean, what the council will let you build, what the permit costs, how tax applies to the purchase and the works, and what you need before the water and electricity can be switched on. Figures are indicative and dated October 2026. Planning is regional and municipal in Spain, so use this as a checklist for questions to the town hall and a local architect.
First question: what is the land?
In Spain the same stone building can be treated very differently depending on its land classification: urban land, a rural nucleus, or open countryside (suelo rústico). That decides whether you may rebuild, what for and how much. Galicia shows how much the answer can vary. There, traditional buildings that predate a 1975 law can, according to Xunta reports citing the regional land law (article 40) and its regulation (article 63), be put to residential use in a rural nucleus, and reformed or rehabilitated, subject to the municipal heritage catalogue. A building classed as outside the plan (fuera de ordenación) can generally receive only conservation works and those needed to keep its existing use. If a house has no licence and is not traditional, the owner may have to prove how old it is; dated photos and historical cadastre records help. Other regions have their own land laws, so a neighbouring region's rules prove nothing. Ask the town hall for a written urban planning report on your exact plot before you sign.
Is it a ruin in the legal sense?
A building can be declared a ruin by the council after a formal procedure. Where repair cost exceeds a legal share of the building's value, the council may decline to allow rehabilitation, and the rule is set locally. A house that is only walls and a few partitions can therefore raise real doubts about whether an integral rehabilitation licence will be granted. Get the council's view, in writing, before you pay a deposit.
The licence: licencia de obra mayor
A rebuild or deep renovation needs a major works licence (licencia de obra mayor), which normally requires a technical project signed by an architect or qualified technician. The cost varies by municipality: portals put the municipal fee plus the construction tax (ICIO) at about 2% to 6% of the material execution budget (another source says 4% to 6%), with ICIO alone often 2% to 4%, and a waste-management bond of about 0.5% of the works. Some councils discount ICIO heavily for works of special municipal interest; the Balearics, for example, allow up to 95% off. These are portal summaries, so read the municipality's fiscal ordinance. The architect's project fee is a separate cost.
Cost per square metre
Portals put a full reform in Spain at EUR 600 to 1,100 per m² in mid-2026, a press article says EUR 850 to more than 1,200 is now common, and a home-improvement retailer gives EUR 700 to 1,500 depending on quality. None of these figures is for a stone village house, so treat them as a floor. Our own judgement, not a sourced figure: structure work on old stone walls, damp, a new roof and long transport distances usually push a village rebuild to the upper end or above. As an illustration, a 100 m² house at EUR 900 to 1,500 per m² means works of about EUR 90,000 to 150,000 before VAT, licence costs and architect fees. Get at least three quotes from builders who have restored stone houses in the same area.
Tax on the works: 10% VAT, if the structure is right
Rehabilitation works on buildings used mainly as housing can be taxed at the reduced 10% VAT rate instead of 21%. According to the Tax Agency and advisers, the main conditions are:
- the contract is signed directly between the owner (promoter) and the contractor, since the reduced rate does not apply to subcontractors;
- at least 50% of the built area is housing;
- more than 50% of the project cost goes to consolidating or treating structure, facades, roofs or similar elements.
Because these conditions are technical, ask your accountant to check the contract and the project before you sign with a builder.
Tax on the purchase
A second-hand home is normally taxed with the regional transfer tax (ITP), set by each region. In Galicia the general rate is 8%, with reduced rates for protected groups. In Castilla y León it is 8% up to EUR 250,000 and higher above that amount (sources differ on the exact bands). The applicable rate follows the date of the deed. Whether a ruin sold as land or as an uninhabitable building is taxed under ITP or under VAT is something we could not confirm, so ask the notary before signing the preliminary contract.
After the works: certificates and utilities
When works end, the architect issues a certificate of completion (certificado final de obra). Many regions then require a habitability certificate (cédula de habitabilidad) or a first-occupation licence, and in some regions the licence replaces the certificate. Utility companies can refuse to start supply without it, so the order matters: permits first, then connections. Electricity needs an installation certificate signed by an accredited installer; a house that never had power usually starts with a temporary construction supply and a connection file. For water, expect a request, inspection, municipal permits and payment for the new connection. Sources conflict on how long a habitability certificate stays valid (10, 15 or 25 years), so ask in your region.
A realistic timeline
These stages are planning assumptions, not statistics: a few months for purchase and checks, several months for the project and licence, then roughly one to two years of works for a full rebuild, with extra time if a heritage or environmental opinion is needed. Do not order the first material before the licence is granted, because building without one can lead to fines or a demolition order.
FAQ
Can I rebuild any ruin I buy? No. It depends on the land classification, whether the building is traditional and registered, and the municipal plan. Ask the town hall in writing before you buy.
Is VAT on renovation 10%? It can be, if the contract is directly with the contractor and the project meets the structural and housing conditions. Check with an accountant before signing.
How much is the licence? Portals suggest roughly 2% to 6% of the works budget including fees and ICIO, but each town sets its own rates and bonuses.
Do I need an architect? For a major works licence, normally yes: it requires a signed technical project.
When can I connect water and electricity? Usually after the completion certificate and the habitability certificate or first-occupation licence, which vary by region.
How we help
We help you check land status and the town hall's position before you commit, put you in touch with local architects, builders and accountants for written quotes, and flag the points that decide whether a ruin is worth rebuilding. Informational only, not legal, tax or investment advice. Planning and taxes differ by region and municipality and change; confirm current terms with the town hall and a qualified professional.
