Building a House in Andalucía | Plot, Licence and Cost in Three Towns

Building a house in Andalucía means taking on the role the law calls the autopromotor, the owner who buys the plot, appoints the architect, applies for the licence and contracts the builder directly. Idealista set out the national picture on 29 October, with building taxes of 3% to 5% of the budget, 10% IVA on a direct build contract and self-build mortgages of up to 80%. On this stretch of coast the numbers are more precise than that, because Marbella, Estepona and Benahavís each set their own rates, and the regional planning law sets the timetable.

The appetite is there. The Colegio de Arquitectos de Málaga approved 386 detached and semi detached houses in 190 separate projects across the province in the third quarter of 2026, with a combined budget of over €111 million, according to figures reported by El Español on 27 October. Marbella completed 102 houses in the same quarter, more than any other town in the province, and Estepona approved 42.

That is barely two houses per project, which points to private owners and small builders rather than large schemes, and most of the buyers we speak to who want a detached villa in our three towns weigh buying a finished home against building one at some point. Both routes end in a new villa, and the numbers on the plot, the build and the resale value decide which is better for a given buyer.

Building a house in Andalucía instead of buying one

The case for building a house in Andalucía rests on control and on margin. An owner who builds chooses the orientation, the layout, the glazing, the materials and the energy standard, and pays no developer profit on top. On a coast where the most sought after homes are modern detached villas with sea views, and where the best finished examples sell quickly, building can be the only way to get exactly the house a buyer has in mind in the location they want.

James Evans, Managing Partner of JUST, made the point about value in a negotiation earlier this year. “If the market ran on a uniform price per metre, neither development nor renovation would be a profession. In every consolidated market a recently completed, high-quality renovation commands a premium, not least because the buyer avoids the cost, the build time, the licensing and the risk of carrying it out themselves.”

The same logic runs the other way for anyone building a house in Andalucía. The self builder takes on that cost, time and risk, and in return captures the premium a finished new house commands.

Demand supports that premium. Writing in September about a group of buyers looking between Guadalmina and the Golden Mile, James noted that “detached villas are the predominant requirement”, and that pattern holds across Marbella, Benahavís and the eastern edge of Estepona. Well located plots with a licence or an approved project are scarce for exactly that reason, and they tend to sell to builders and private buyers alike.

Choosing a plot for building a house in Andalucía

Building a house in Andalucía starts with the land. A plot classified as urban, and in particular one already recognised as a solar with roads, water, power and drainage reaching it, can take a house under the general plan. Rustic land is a different matter. The LISTA, Andalucía’s planning law of 2021, does allow a detached house on suelo rústico as an extraordinary use, but its regulation requires at least 2.5 hectares, at least 100 metres to any other dwelling, a footprint of no more than 1% of the plot and a compensation payment of 15% of the construction budget.

In practice, building a house in Andalucía on the coast means an urban plot inside an established urbanisation. In Benahavís that might be La Zagaleta, El Madroñal, Los Arqueros or the hills above La Quinta. In Marbella it is Sierra Blanca, Nagüeles, Cascada de Camoján, Los Monteros and the urbanisations along the eastern coast. In Estepona it is El Paraíso, Atalaya, Valle Romano and the New Golden Mile hillsides. Each has its own buildability, height limits and setbacks under the general plan, and occasionally its own private rules on top.

Slope matters more to building a house in Andalucía’s coastal hills than almost anywhere in Spain. The national building code treats ground with a gradient above 15 degrees as unfavourable, which means more investigation and usually more concrete in the foundations and retaining walls. A hillside plot in Benahavís with a view over the coast will cost more to build on than a flat plot in Nueva Andalucía of the same size, and the price of the land should reflect that. Our guide to Benahavís sets out where the main urbanisations sit.

We hold the planning parameters, cadastral data and sold prices for plots across all three municipalities, built up over years of work on this coast. Before an offer goes in, we can tell you what the plan allows on a given plot, what the slope will mean for the build and what comparable plots have actually sold for.

The planning framework for building a house in Andalucía’s three western towns

Marbella approved its new general plan, the PGOM, at an extraordinary council meeting on 18 September 2026, and it is the first plan in Andalucía adapted to the LISTA. It takes effect once published in the provincial bulletin, and a detailed ordinance plan follows. Our post on the PGOM approval covers what changes, and the council’s January 2026 instruction on licences, covered in our post on the Marbella building licence threshold, has already removed the need for prior permission on small works.

Benahavís still works from the revision of its general plan approved by the Junta in 1997 and republished in the regional bulletin in 2022, with a new plan at an early stage. Estepona’s general plan also dates from the 1990s, with later partial adaptations. Neither fact stops anyone building a house, but it does mean the detail of what a plot allows sits in older documents and later amendments, and reading them correctly is specialist work.

The licence, the timetable and first occupation

Building a house in Andalucía always needs a full building licence, the licencia de obra mayor, supported by an architect’s project approved by the Colegio de Arquitectos and a geotechnical study carried out at the start of the design. Under article 140 of the LISTA the council has three months to decide once the file is complete. For new buildings, though, silence does not mean consent, because state law requires an express decision, so the clock is a target for the council rather than a guarantee for the owner.

Once granted, the licence gives one year to start the works and three to finish them, and extensions are available for up to the same periods. At the end, first occupation in Andalucía is now handled by a declaración responsable rather than a separate licence, filed with the final works certificate signed by the architect and site engineer. The new build deed is then signed before a notary, registered in the Registro de la Propiedad and the house is added to the Catastro.

Marbella’s mayor set a target of four months for an average licence back in 2019, down from as long as a year and a half. Building a house in Andalucía with a complete, well prepared file is the single biggest thing that keeps the timetable short.

Taxes and fees on building a house in Andalucía

Three municipal charges fall on anyone building a house in Andalucía’s coastal towns. The ICIO, the tax on construction works, is 4% of the budget in Marbella, 3.5% in Estepona and 2.4% in Benahavís, according to each council’s published ordinance. The licence fee is 0.719% of the cost of the works in Marbella, 1.1% in Estepona and 0.7% in Benahavís. There is then a smaller fee for first occupation, of 0.308%, 1.1% and 0.2% respectively.

Councils do not simply accept the owner’s budget as the tax base. Marbella, for example, sets a minimum base using the construction values published each year by the Colegio de Arquitectos de Málaga, which for 2026 put an average quality detached house at €1,341 per square metre, with adjustments of minus 20% to plus 50% for specification. On a 400 square metre house at that module, the three municipal charges come to roughly €27,000 in Marbella, €30,600 in Estepona and €17,700 in Benahavís.

Building a house in Andalucía also carries IVA at 10% on the construction contract when the owner contracts the builder directly, and on fitted kitchens and wardrobes supplied under the same contract. Architects, engineers and project managers charge 21%. The new build deed pays stamp duty, the AJD, at 1.2% in Andalucía on the cost of the works, and the same 1.2% rate applies to a mortgage deed, although since November 2018 the bank, not the borrower, pays the AJD on a mortgage.

The plot has its own tax treatment when building a house in Andalucía. A building plot sold by a company or developer carries 21% IVA plus 1.2% AJD, while one sold by a private owner pays transfer tax, the ITP, at a flat 7% in Andalucía. On a €2 million plot that difference is significant, and it is one of the first things we establish when a plot comes up.

Insurance, finance and the budget for building a house in Andalucía

The ten year structural insurance, the seguro decenal, is compulsory for developers but not for an individual building a single house for their own use. If the owner sells within ten years, though, the buyer must either be covered for the remaining years or expressly release the seller before a notary, so most owners take it out from the start. Idealista puts the cost at 0.55% to 1.5% of the material budget, and banks financing a build usually insist on it along with all risk construction cover.

For building a house in Andalucía with finance, a self build mortgage is released in stages as an appraiser certifies progress on site, and Spanish banks typically lend up to 80% of the lower of the construction budget and the final valuation, over a maximum of 30 years. The loan covers the build, not the plot. Our post on the Andalucía mortgage market covers where rates stand, and many of our buyers fund the land in cash and borrow only against the construction.

The Colegio module is a tax reference, not a market price. A high specification villa in Marbella or Benahavís, with basements, a pool, large glazing, home automation and landscaped terraces, costs well above it. We know what comparable houses on this coast have cost to build and what they have sold for once finished, and setting a project against those numbers is the surest way to budget properly before the plot is bought.

Selling a plot with a project, or a finished house

Not every owner who sets out on building a house in Andalucía finishes the job, and a plot with a licensed project is a product in its own right. When an owner asked us this October to market a plot in Benahavís with a project attached, James set out what buyers look for. “What will matter most to buyers is the project itself, so the status of the building licence, the architect’s plans and any topographical or geotechnical surveys.” A licence in hand can take a year or more off a buyer’s timetable, and it is priced accordingly.

At the other end, a newly completed house sells against the finished stock in each area, and our Marbella property market report, Benahavís report and Estepona report show what new villas are achieving. The valuation calculator is the quickest way to see where a plot or a house sits today, and our buyers guide covers the purchase side, from the NIE to completion.
