Urban Information System Madrid 2026: what changes for developers and urban planners

Key data

Real estate developers and urban planners operating in Madrid have had access since April 28, 2026 to a more complete and up-to-date urban planning database. The General Directorate of Housing and Land has published the collaboration agreement with the Community of Madrid for the development of the Urban Information System (SIU), a national system that centralizes land and planning data.

The agreement, contained in the Resolution of April 17, 2026 published in the BOE, does not impose direct obligations on private companies nor establish sanctions, but does open a path to access official information that until now was more fragmented between administrations.

What does this regulation establish?

The agreement formalizes collaboration between the General Administration of the State, through the General Directorate of Housing and Land, and the Community of Madrid for the joint development of the Urban Information System (SIU).

The specific elements of the agreement are as follows:

• Exchange of cartographic information between both administrations on Madrid's territory.
• Exchange of statistical data related to land and urban development.
• Exchange of urban planning information: land classification, current planning and urban uses in Madrid.
• Centralization in the SIU: all this data is integrated into the national urban information system to improve territorial planning.
• Strengthening of administrative transparency in territorial planning matters.

The SIU is the Ministry of Housing platform that aggregates urban planning data from across the national territory. This agreement extends its coverage and data quality for the Community of Madrid, one of the regions with the highest real estate and urban planning activity in the country.

Economic and operational impact

This agreement does not generate direct costs for private companies nor establish new fees or sanctions. Its impact is fundamentally operational: it improves the quality and availability of official urban planning information for those working in the sector.

The most relevant practical implications are:

• Reduction of uncertainty in investment decisions: having updated official data on land classification and planning reduces the risk of errors in land valuation or project feasibility assessment.
• Streamlining of procedures: centralized access to planning data can facilitate the preparation of license applications and urban management procedures with the Madrid administration.
• Better basis for real estate due diligence: developers and investment funds acquiring land in Madrid will be able to verify classifications and uses against more complete and updated official data.
• More precise territorial planning: for urban planning and architecture firms, having integrated official cartography and statistical information reduces the time spent on preliminary project analysis.

No data is available on system implementation costs or budget allocated to the agreement, as the regulation does not specify them.

Who does it affect?

• Real estate developers developing projects in the Community of Madrid: better access to land classification and planning data to evaluate land and project feasibility.
• Urban planners and architects working on planning or urban projects in Madrid: access to more up-to-date official cartography and statistical information.
• License managers and urban processing specialists: data centralization can facilitate application preparation and verification.
• Investment funds and family offices with real estate assets in Madrid: better database for due diligence on land and urban assets.
• Law firms specializing in urban planning: more direct access to official information on current planning to advise clients.
• Local public administrations of the Community of Madrid: integration of their urban planning data into the national system.
• Madrid citizens who need to consult information on land classification or planning in their municipality.

Practical example

A real estate development company is evaluating the acquisition of a plot in a municipality of the Community of Madrid to develop a residential project. Before this agreement, the technical team had to separately consult municipal planning, cadastral data, cartography from the Community of Madrid and records from the Ministry of Housing to obtain a complete picture of land classification and permitted uses.

With the agreement in force, the Urban Information System (SIU) integrates cartographic, statistical and urban planning information from the Community of Madrid into a single official access platform. The developer's team can verify land classification, current planning and urban uses directly from the SIU, reducing preliminary analysis time and minimizing the risk of working with outdated or contradictory data from different sources.

This centralized access is especially relevant in land operations where urban classification directly determines asset value and project feasibility.

What should companies do now?

1. Identify if the SIU is relevant for your projects in Madrid: if your activity involves land analysis, planning or license management in the Community of Madrid, the Urban Information System is an official source that should be incorporated into your workflows.
2. Review available data in the SIU for ongoing projects: verify the land classification and planning of the assets or land you are analyzing against the updated data now integrated into the system following the agreement.
3. Update due diligence procedures: if you acquire land or real estate assets in Madrid, incorporate consultation with the SIU as a standard step in the urban verification process.
4. Inform technical teams: urban planners, architects and license managers in your organization should be aware of the availability of these updated official data to optimize their analysis and procedures.
5. Monitor the implementation of the agreement: given that the operational entry into force date is not specified, it is advisable to monitor SIU updates and communications from the General Directorate of Housing and Land to know when Madrid's data is fully integrated.
