The Supreme Court brings to mind when the Administration’s financial liability for reduction in buildable area arises

Changes to urban planning that reduce land use give rise to a large number of financial liability claims by affected owners, who consider their economic expectations to have been harmed by the loss of profitability resulting from the new urban planning regime.

Recently, the Supreme Court, from its Contentious-Administrative Chamber, in its judgment of 5 February 2026 (appeal 3646/2023), analysed this issue in relation to a specific modification of the Barcelona Metropolitan General Plan, which allocated certain land to public housing, with the consequent reduction in its profitability. The claimant owner argued, on the basis of Article 48 of Royal Legislative Decree 7/2015 of 30 October, which approves the revised text of the Land and Urban Rehabilitation Law (TRLSRU, its Spanish acronym), that the new zoning had caused him compensable economic damage, insofar as such limitation was not susceptible to equitable distribution.

In its judgment, the Supreme Court rejected the appellant’s argument and established as a decisive criterion that “compensation for damages is only applicable when the right limited by the zoning is not a mere expectation, but has materially affected the owner’s assets”.

This criterion is based on Article 11.2 TRLSRU, relating to the urban planning regime for land ownership rights, which establishes the following: “The provision of buildability by land use and urban planning regulations does not, in itself, form part of the content of land ownership rights. The patrimonialisation of buildability occurs only with its effective realisation and is in any case conditional upon the fulfilment of the duties and the lifting of the burdens inherent in the corresponding regime, under the terms provided for by the legislation on land use and urban planning”.

The Supreme Court also emphasises that its doctrine is unequivocal on this point and cites numerous rulings, including its judgment of 17 May 2012 (appeal 1178/2010), in which it maintains the same criterion, establishing that “there is no basis for compensation because it is only possible to speak of compensable deprivation when the restriction affects rights or contents that have already been capitalised”.

Consequently, as long as the urban development has not been effectively incorporated into the owner’s assets – through compliance with the applicable urban planning obligations and duties – the reduction in buildable area remains in the realm of expectations and does not constitute compensable damage.

The judgment thus reaffirms, once again, that, in urban planning matters, financial liability is not based on expectations, but only on established legal realities.
