On Friday 18 September 2026, Marbella's council gave final approval to its Plan General de Ordenación Municipal. The vote carried with PP, OSP and Vox in favour and PSOE abstaining. No councillor voted against. Marbella is now the first municipality in Andalucía with a general plan adapted to the LISTA land law, and the 1986 plan, which has governed every licence in the city for forty years through annulments, court rulings and a dissolved town hall, has a successor.
Our report of 15 September set out the approval as one of three clocks running against the buyer who waits. That clock has now struck. This report covers what the vote changes, what it leaves untouched, and where the repricing lands first.
The Numbers the Plenary Confirmed
Urban land classification rises from roughly 40 million to 53 million square metres, an increase of about a third. New developments on urban land must reserve 20% of their buildability for affordable housing. The plan fixes the structural systems: green corridors running from the sierra to the coast, road connections, cycling networks, parking, water, sewerage and energy networks, and a reserved alignment for the future coastal rail link.
The figure that made the headlines is the irregular housing stock. The mayor put it at approximately 18,000 homes lacking planning regularity. Our earlier report used 16,500, the figure in circulation during the drafting phase for homes built between 1991 and 2006 outside the old plan. The plenary number is the higher one and it is the one now on the record. At Marbella's twelve-month deed average of €4,665 per built square metre, 18,000 homes is a block of several billion euros of residential value that has been trading under a legal cloud for two decades.
What Changes the Day the Plan Is Published
The plan does not take effect on the day of the vote. It takes effect the day after the plenary agreement and the planning norms are published in the official bulletin. From that date, five things are law: the classification of every square metre as urban or rustic, the structural systems and growth areas, the environmental protections, the rustic land regime, and the transitional status of existing buildings.
Three transitional provisions matter to capital.
Provision five protects development schemes that already hold final approval. They keep their validity until fully executed. A licensed plot bought last year is a licensed plot today.
Provision six allows urban transformation projects on the new plan's terms to be delimited and ordered before the detailed plan exists, provided they meet the new standards for public facilities and open space. This is the fast lane for professional developers with land in the newly classified 13 million square metres.
Provision one sorts non-conforming buildings into two grades. Total incompatibility is reserved for buildings that sit on public facility land or block a road. Everything else is partial incompatibility, where repair, renovation, conservation and improvement are permitted so long as the non-conforming parameter is not made worse. For most owners of the 18,000 homes, that is the line between an asset that can be financed, insured and upgraded and one that cannot.
What Does Not Change
Heights, buildability, alignments and detailed uses remain under the 1986 ordinances until the Plan de Ordenación Urbana is approved. The POU advance was published in May 2024. The town hall speaks of spring 2027. The authors of the plan and most practitioners expect 2028 or 2029. Until then a buyer who wants to know what can be built on a given plot still reads the 1986 rules.
The second point needs to be stated plainly, because the headlines will blur it. The PGOM does not legalise 18,000 homes by decree. The identified irregular groupings pass into a regime assimilated to out-of-ordination status under the LISTA regulation, pending a special plan that will give them detailed ordering. A property with an annulled licence, an unlicensed extension or a boundary that ignores the cadastre has a route to regularisation that it did not have on Thursday. It does not have a clean file. Each asset still requires its own legal analysis, and the cost and timing of regularisation will differ street by street.
Third, a general plan can be challenged in the administrative courts after publication. The 2010 plan was annulled by the Supreme Court in 2015, which is how Marbella ended up back under the 1986 text. The 2026 plan was drafted with that history in mind. It carries more than sixty favourable sectoral reports, the Junta's sign-off of 22 February 2026, and the coastal authority's favourable report of 5 September. It passed without a single vote against, which removes the political motive for a challenge. The residual risk is low. It is not zero, and counsel should say so in every due diligence report written this year.
Where the Repricing Lands First
Planning certainty does not lift all values equally. It sorts them.
Clean assets reprice first. Homes with licence, first-occupation certificate and cadastral alignment in order are the benchmark against which the newly regularisable stock will be measured. They were already scarce. They are now the reference price.
Regularisable stock becomes a legal arbitrage. An asset in partial incompatibility, bought at the uncertainty discount and carried through the special plan to a clean file, captures the gap. This is work for buyers with specialist counsel and a three to five year horizon. It is not a trade for the casual purchaser, and the discount will narrow as each special plan advances.
Licensed plots in established urbanisations keep their monopoly. The new urban land is supply on paper. It needs the POU, a transformation project, urbanisation works and then licences before it delivers a single villa. Serviced plots with licences in hand in Marbella, Benahavís and neighbouring Mijas remain the only deliverable new-build product through at least 2028. Anything licensed now is also built to current NZEB compliance Spain standards, ahead of the next tightening of the Código Técnico, which is the definition of high-performance real estate with a rising replacement cost.
Sightlines are now a matter of public record. Every plot facing newly protected rustic land or a structural green corridor holds a permanent view. Every plot facing newly classified urban land will lose one. The map is published. Few buyers have read it.
The 20% affordable reserve lowers the free-market yield of every new sector. Developers will bid for the new land with that reserve in their numbers, which caps the volume of prime product the 13 million square metres can ever release. For holders of existing prime stock this is a structural support for Costa del Sol capital appreciation, not a threat to it.
The Trade From Here
The first quarter of 2026 saw Golden Triangle transactions fall 35.6% against the previous quarter while prices held flat. That was a market waiting for a decision. The decision is made. The buyers who held back through the spring have no remaining reason to wait, and they return to a market where sellers have not yet repriced for the news.
That gap between a settled legal framework and unadjusted asking prices is short-lived. It closes when the plan appears in the bulletin and the first post-approval deeds print, which on the normal lag means the spring of 2027. The fourth-quarter window described on 15 September is unchanged in timing and stronger in logic.
Two instructions for any acquisition in Marbella from this week. Commission a planning report against the new PGOM classification, not the 1986 plan alone, and have counsel state the property's transitional status in writing. Then check the sightline against the published structural map. Both steps cost little. Skipping either is how buyers overpay in a repricing market.
While the market data supports the investment, the acquisition of these specific assets is managed exclusively by our brokerage partner, Domus Venari. Current inventory is concentrated in clean-title Marbella resales, licensed plots in east Marbella and Mijas, and the Domus Venari EcoVillas portfolio, all of which sit on the right side of the new plan.
