Marbella’s New PGOM: What It Actually Changes for Buyers, Owners and Developers

Marbella's planning story has been unusually messy for a town this wealthy. For a decade, one of Europe's most valuable property markets operated under a masterplan approved in 1986, after the more modern 2010 plan was struck down by Spain's Supreme Court in 2015. That left buyers, owners and developers navigating a patchwork of transitional rules rather than a single, coherent framework.

That has now changed. On 18 September 2026, at an extraordinary plenary session, Marbella's council gave definitive approval to its new Plan General de Ordenación Municipal. It is the first general plan in Andalucía to be approved under the region's LISTA law, and it replaces, in its general planning determinations, the framework the city had operated under since 1986.

This article sets out exactly what has been approved, what is still pending, and what any of it concretely means if you own or are considering buying property in Marbella. The short version is that the headline is real and the caveat is also real: the strategic framework is now settled, and the detailed rules that govern what you can build on a specific plot are not.

Two acronyms come up throughout, so a quick note on what they stand for. PGOM stands for Plan General de Ordenación Municipal, a municipality's general urban plan: the strategic, town wide document that sets out how Marbella can develop overall. POU stands for Plan de Ordenación Urbana, the urban execution plan: the separate, far more detailed document that sets the specific rules for individual plots and streets. The distinction between the two is exactly what most coverage muddles.

Marbella approved a new masterplan in 2010, only for Spain's Supreme Court to annul it in 2015 over procedural defects, a ruling that forced the town back onto its 1986 plan by default. An urban plan drafted in 1986 predates Marbella's modern population size, its current environmental protections and decades of infrastructure growth, so operating under it created exactly the kind of legal uncertainty that discourages serious long term investment: unclear building rights, inconsistent rulings on renovations and extensions, and periodic legal challenges to individual permits.

The fix came through regional legislation. In 2021, Andalucía passed the LISTA law, the Ley de Impulso para la Sostenibilidad del Territorio de Andalucía, replacing the previous planning law and introducing a faster, more structured process for municipalities to approve general plans. Marbella has now become the first municipality in Andalucía to complete its planning process under that law, which is why both regional officials and the mayor have described it as a genuine milestone rather than routine administrative news.

The definitive approval came at an extraordinary plenary session on Friday 18 September 2026.

The vote carried with the governing PP group, OSP and VOX in favour, and the PSOE abstaining. That breakdown is worth noting, because it tells you something about how the plan is regarded politically. VOX supported it while making clear that a favourable vote did not mean endorsing every determination in the document, and criticised the absence of new growth areas. The PSOE abstained, with its spokesperson describing a new plan as essential while warning that the PGOM cannot be judged separately from the decisions the council takes next, and pointing out that the plan does not by itself determine the detailed fate of individual plots.

On that last point, the opposition and this article agree entirely, and it is the single most important thing for a buyer to understand.

The planning councillor framed the approval as the culmination of years of technical work and at the same time the beginning of a new stage for the city. That is a fair description of where things now stand.

The headline figures, now confirmed rather than projected:

Urban land rises from roughly 40 million m² to 53 million m². That is the central change, and it reflects a municipality whose real extent had long outgrown the land its 1986 plan recognised as urban.

Twenty percent of buildable area is reserved for affordable housing in actuations proposed on urban land. This is the plan's principal housing measure and it applies going forward rather than retroactively.

Land is reserved for infrastructure, including new road connections, an expansion of the Hospital Universitario Costa del Sol, a future Ciudad de la Justicia, and, notably, reservations for a future rail connection. The rail reservation is a long term provision rather than a funded project, but reserving the land is the step that makes it possible at all.

Provision is made for new development, public housing, facilities, green space and land for economic activity, which is the standard content of a general plan and the part that the POU will translate into specific rules.

This is the part of the approval most relevant to existing owners, and the part most likely to be misreported, so it deserves care.

The mayor stated that around 18,000 homes in Marbella had fallen outside planning regularity as a consequence of the municipality's complicated planning history, and described the new framework as a guarantee for good faith third parties and for the families connected to those properties. In plain terms: over decades of annulled plans, annulled licences and shifting rules, a great many perfectly ordinary homes ended up in an irregular position through no fault of their current owners.

The PGOM provides a regulatory basis from which those situations can be addressed. That is genuinely significant and it is the reason the approval matters to owners as much as to developers.

What it does not do is regularise any individual property automatically. Approving a new general plan does not by itself resolve inherited legal situations such as annulled licences or buildings in a fuera de ordenación position. Those continue to be assessed case by case, and the new land classifications change the framework within which they are assessed rather than curing the underlying defect.

If you own, or are buying, a property whose status is uncertain, the practical advice has not changed: have your own lawyer establish the specific position of that specific property. What has changed is that the framework they are working within is now a modern one rather than a plan from 1986.

Here is the distinction that matters most for anyone buying with renovation or development in mind, and it survives the approval intact.

The PGOM is the strategic document. It classifies land across the municipality and sets the overall growth model and the reserved areas for major public infrastructure. What it does not do is set the detailed, plot level rules, building heights, buildable ratios, setbacks and street level technical standards, that a lawyer or architect actually needs to assess a specific property.

That level of detail comes from the POU, which Marbella Town Hall is developing in parallel and which remains in process. Initial approval has been expected during 2026, with final approval realistically in 2027 to 2028.

In practical terms: the PGOM lays the legal foundation and removes the underlying uncertainty of operating under a 1986 plan, which is genuinely significant. But the specific rules determining what you can build, renovate or extend on a given plot are still being finalised and will not be fully settled for at least another year or two.

Two things, in order.

Publication and entry into force. The approved plan is published in the official bulletin, and from that point new licence applications are processed under the PGOM's parameters. Until publication is complete, confirm the position with your lawyer rather than assuming the new framework already governs your application.

The POU. The plan of record for individual plots. Initial approval during 2026 and definitive approval expected in 2027 or 2028. This is the document to watch if your plans depend on a specific building right, and it is where the practical consequences of the PGOM will actually land.

For most buyers of finished, existing homes, this changes little day to day. The effect is the removal of long term legal uncertainty at the municipal level, a background factor that supports market confidence rather than something that touches an individual transaction.

For owners of property with an irregular planning history, the approval is more meaningful, because it creates the framework from which those situations can be resolved. It does not resolve them by itself, and anyone in that position should take advice on their specific property rather than reading the headline as a solution.

For anyone buying with renovation, extension, demolition and rebuild or new development in mind, the honest position is this: the general direction of travel is now settled rather than merely likely, which is a real improvement, but the specific plot level rules may still change as the POU is finalised. Any purchase decision that depends on a specific building right, an extra floor, a larger buildable footprint, a change of use, should have that right confirmed in writing against the current rules rather than assumed from the PGOM headlines.

For developers and larger investors, the additional urban land and the reserved infrastructure zones are now confirmed rather than proposed, which makes them worth studying properly. Areas newly classified as urban, or positioned near the reserved infrastructure, are the natural candidates for the next development cycle.

The PGOM's effects will land unevenly across Marbella, and the areas we work in most illustrate why.

Sierra Blanca and the Golden Mile are already largely built out, so the relevance here is less about new land and more about the POU's eventual rules on demolition and rebuild projects, height and buildable ratio on existing plots, exactly the kind of project much of Sierra Blanca's current market is built around. See our Sierra Blanca guide for the area in detail.

Nueva Andalucía, with its mix of established and still evolving development, is one of the areas most likely to see practical change once the POU's zone by zone rules are published, particularly around any land newly classified as urban.

East Marbella, Elviria and Hacienda Las Chapas still has genuine building plots coming to market, which makes the detailed buildability rules in the POU especially relevant: what a specific plot can support will matter more to value here than almost anywhere else on our patch. See our Hacienda Las Chapas guide.

La Zagaleta and Benahavís, being a separate municipality with its own long standing, low density planning regime, are unaffected by Marbella's PGOM directly, though the regional shift toward LISTA based plans may eventually reach Benahavís too.

• The current planning status of the specific property, confirmed with an independent lawyer or architect, not assumed from the PGOM's approval.
• Whether the plan has been formally published and is therefore in force for licence applications.
• The POU's progress on the specific zone your property sits in, since detailed plot level rules will phase in over the coming one to two years rather than all at once.
• Any existing building licence or planning permission, and whether it remains valid and unaffected by the transition between frameworks.
• The specific position of any property with an irregular history, which the PGOM makes addressable but does not resolve automatically.
• Reserved land and infrastructure plans nearby, which can materially affect a property's setting, access or future value, for better or worse.

Has Marbella's new PGOM been approved?

Yes. Marbella's council gave it definitive approval at an extraordinary plenary session on 18 September 2026, with the governing PP group, OSP and VOX voting in favour and the PSOE abstaining. It is the first general plan in Andalucía approved under the LISTA law.

Does that mean the 1986 plan is gone?

In its general planning determinations, yes. The PGOM replaces the framework Marbella had operated under since 1986. The detailed rules for individual plots still come from the POU, which is not yet finalised.

What is the difference between the PGOM and the POU?

The PGOM is the strategic, municipality wide plan: it classifies land and sets the overall growth model. The POU is the detailed execution document that sets the specific rules, building heights, buildable ratios and setbacks, for each zone. The POU remains in process, with definitive approval expected in 2027 or 2028.

Does the new PGOM mean I can build more on my plot?

Possibly, but not automatically. The PGOM increases the overall amount of land classified as urban and sets a modern general framework, but the specific buildable rights for an individual plot depend on the detailed rules still being finalised in the POU. Confirm your specific situation with a lawyer or architect rather than assuming a general entitlement.

Does the PGOM regularise the 18,000 homes that were outside planning regularity?

Not by itself. The town hall describes the plan as providing a guarantee for good faith third parties and a regulatory basis from which those situations can be addressed. But approving a general plan does not automatically cure an annulled licence or a property in a fuera de ordenación position. Those are still assessed case by case, and anyone affected should take advice on their specific property.

How much urban land does the plan classify?

Around 53 million m², up from roughly 40 million m² under the 1986 framework.

What does the plan do about housing affordability?

Actuations proposed on urban land will reserve 20% of buildable area for affordable housing. The plan also makes provision for public housing more broadly.

Why did Marbella need a new plan at all?

Marbella had operated under a 1986 plan since 2015, when the Supreme Court annulled the town's more modern 2010 masterplan. That left the municipality without an up to date legal framework for building rights, environmental standards or infrastructure planning for roughly a decade.

When we first published this article in July, our caution was that "Marbella enters a new era" made a better headline than "Marbella is partway through a multi year planning transition." The first half of that has now happened, and it deserves to be recognised properly. Ending a decade of legal limbo, and doing it as the first municipality in Andalucía under a new regional law, is not a small achievement.

The second half of the caution stands unchanged. What you can actually build on a specific plot, and under what rules, depends on the POU, which is still a year or more from being finalised. The uncertainty has not disappeared. It has moved from "when will Marbella get a modern plan" to "what will the specific rules for my zone say." One of those questions is now answered. The other is not.

The 18,000 homes point deserves the same treatment. It is the most consequential thing in the announcement for ordinary owners, and it is also the thing most likely to be read as more than it is. A framework from which irregular situations can be resolved is a real and welcome change. It is not the same as those situations being resolved. If that description fits your property, this is the moment to get proper advice, not the moment to assume the problem has gone away.

The details that matter most to a specific property will emerge as the POU is finalised over the next year or two. If you are considering a purchase where future building rights matter, whether a renovation project in an established area or land in a newly classified zone, our guides to buying property in Marbella and to new build and off plan homes cover the wider process in detail, and our Marbella property market report sets out the current picture.
