Marbella’s New General Municipal Development Plan: Key Impacts on Land and Housing

The Junta de Andalucía has officially approved Marbella’s New General Municipal Development Plan (PGOM). With the regional and environmental clearances complete, the Marbella municipal council gave the PGOM its final approval on 18 September 2026, in a plenary session. The plan passed with one party abstaining from the vote.Marbella is now the first municipality in Andalusia with a General Municipal Development Plan fully adapted to the LISTA law. This approval replaces the outdated urban planning rules the city has relied on for years and establishes a legally secure foundation for future development. Here is a breakdown of what the new PGOM means, how it classifies municipal land, and how it will impact the local real estate sector.

The Historical Context: Replacing the 1986 PGOU

To understand the importance of the new Plan General de Ordenación Municipal (PGOM), it is necessary to look at the legal framework under which Marbella has been operating.In 2015, the Spanish Supreme Court annulled Marbella’s 2010 urban masterplan. This legal decision forced the municipality to revert to its previous masterplan, the 1986 PGOU (Plan General de Ordenación Urbana).Operating under a planning document that was drafted in 1986 presented significant challenges. The old regulations did not account for Marbella’s current population size, modern environmental protection laws, or infrastructure needs. This created legal uncertainty for developers, property owners, and investors. The approval of the new PGOM officially retires the 1986 framework, replacing it with a modernised, legally compliant system.

The LISTA Law

With this regional approval, Marbella has become the first municipality in Andalusia to fully adapt its urban planning to the 2021 regional law known as LISTA (Ley de Impulso para la Sostenibilidad del Territorio de Andalucía).The LISTA law was introduced to simplify and speed up urban development across the region. It achieves this by splitting traditional, complex city plans into two separate documents:

• The PGOM (Plan General de Ordenación Municipal): This is the strategic document that has just been approved. It defines the macro-level layout of the city, classifies the land, and outlines major infrastructure and environmental protections.
• The POU (Plan de Ordenación Urbana): This is the detailed management document. It dictates specific micro-level zoning rules, such as building heights, neighbourhood street layouts, and technical construction standards.

The PGOM provides the overall strategy, while the POU (which is currently still being processed by the city) will provide the exact execution details.

Land Classification Breakdown

The PGOM maps out the entirety of Marbella’s municipal area, which totals 117 million square meters. The plan categorises this land to dictate exactly where and how development can occur.

1. Urban Land (53 million square meters)

This category covers the land that is already developed and consolidated. It includes existing residential neighbourhoods, commercial districts, and established city infrastructure. By officially classifying this land as “urban,” the PGOM provides immediate legal security to current property owners and businesses in these areas.

The new plan also addresses the roughly 18,000 homes left in legal limbo by decades of planning uncertainty, many built in good faith under plans that were later annulled. The council has said the PGOM gives these owners greater legal certainty in the future.

2. Rustic Land (64 million square meters)

This category covers the undeveloped land outside the consolidated city zones. Under the PGOM, rural land is carefully managed to prevent uncontrolled urban development.

The Rules for “Urban Transformation”

Out of the 64 million square meters of rural land, the PGOM identifies 30 million square meters as susceptible to “urban transformation.”This designation means the land can potentially be developed in the future, but it does not grant automatic building rights. Any future development on this land must strictly adhere to the sustainability, environmental, and infrastructure requirements laid out in the PGOM.One of the most significant requirements in the new PGOM addresses Marbella’s housing supply. Due to high demand in the luxury real estate sector, average property prices in Marbella have grown significantly, making it difficult for residents to secure housing. To counter this, the PGOM enforces a strict residential quota on new developments.

Here, the PGOM reserves 20% of new residential buildable area for affordable housing for people like teachers, healthcare and hospitality workers, etc.

Environmental Clearances and Sustainability

The favourable decision from the Junta de Andalucía means that the PGOM has officially passed all regional environmental evaluations.The document integrates modern environmental standards that were absent in the 1986 plan. Key sustainability features include:

• Strict borders to contain urban development
• The protection of designated natural areas, forests, and mountain zones.
• The establishment of green corridors connecting different parts of the municipality.
• Provisions for sustainable mobility and public transport infrastructure.

Real Estate Market Implications

For the Costa del Sol real estate market, the approval of the PGOM provides a vital resource: legal certainty. The previous reliance on the 1986 plan created a landscape of administrative delays and legal disputes over land classification. This deterred some institutional investors and complicated the permitting process for developers.The regional approval of the PGOM resolves this ambiguity. It offers clear, legally backed guidelines. For developers, financial institutions, and property buyers, this clarity significantly reduces investment risk and provides a reliable framework for long-term project planning.

Next Administrative Steps

With municipal ratification complete, one step remains: the POU is still being processed by the city and will set the detailed, street-level zoning rules like building heights, neighbourhood layouts, and technical construction standards that give the PGOM its practical effect.
Until the POU is finalised, the PGOM provides the legal framework, but some of the zoning detail buyers and developers will eventually need is still to come.

Conclusion

Marbella’s approval of its new PGOM marks a new era in the city’s urban planning. After decades under the 1986 framework, and following the annulment of the 2010 plan, the city now has a modern, legally secure masterplan aligned with current environmental standards and the LISTA law; the first of its kind in Andalusia.
The plan brings clarity to land classification, expands the urban land base by roughly 13 million square meters, and introduces housing quotas on both transformable rustic land and urban land to support balanced growth. It also offers greater legal certainty to the roughly 18,000 homes affected by decades of planning uncertainty.
For property owners, developers, and investors, this means a far more predictable framework for future projects. The remaining piece is the POU that will provide more detail over the coming months.
