The Risk of a Change to the Urban Plan: How to Assess It
Catalan law gives no right to compensation merely because a plan changes. Protection builds up stage by stage: approved plan, urbanisation projects, licence. The risk has to be measured by stage.
The risk of a plan change cannot be removed, but it can be measured. It depends on the stage a plot has reached and on whether there is a licence. Catalan law states directly that urban zoning in itself gives no right to compensation. The right arises at later stages: with an approved derived plan, urbanisation and reparcelación projects, or an issued licence.
What the law says about compensation
Urban zoning of plots only defines the content of the property right, so it gives no right to claim compensation, except in cases the law names expressly (art. 6 Llei d'urbanisme, the Catalan Urban Planning Law). The national law adds the second half: permitted floor area becomes part of the property right only when it has actually been built, and provided the obligations have been met (art. 11.2 RDLeg 7/2015).
In practice this means a plot with an area "permitted by the plan" does not yet own that area.
The law names compensation in the cases listed in art. 48 RDLeg 7/2015. They include: a change to the urbanisation conditions before the planned deadlines expire, a change to or termination of a licence because of a later change of plan, revocation of a licence, and unjustified delay or refusal.
How protection grows by stage
| Stage of the plot | Position on compensation | Rule |
|---|---|---|
| Land merely classified by the plan | No right to claim compensation | Art. 6 Llei d'urbanisme |
| A plan exists, but no urbanisation and reparcelación projects | No compensation for the lost right to take part in urbanisation | Art. 115.3 Llei d'urbanisme |
| Plan and urbanisation and reparcelación projects approved | Compensation possible if the planned deadlines have not yet passed | Art. 48 RDLeg 7/2015, art. 115.3 |
| Licence issued, then the plan changed | Compensation for the change or termination of the licence | Art. 48 RDLeg 7/2015 |
| Building built, then found to be outside the plan | The status of fuera de ordenación (out of planning) is not compensated, but the impossibility of using the building may be | Art. 48 RDLeg 7/2015 |
Compensation covers the loss and does not restore the project. Its amount is determined under the land law, and disputes are settled by the courts.
How a plan change reaches a plot
A plan change begins with its first approval (aprobación inicial), and from that moment the ayuntamiento must suspend the issuing of licences in the areas where the new rules change the regime (art. 73.2 Llei d'urbanisme). The suspension lasts no more than a year, or no more than two years where grounds accumulate (art. 74.1). It can be repeated for the same area with the same purpose no sooner than three years after it ends (art. 74.2).
This gives you a signal. The decision to suspend is published in the official gazette and tied to an area on a map (art. 73.3). If commissioned projects have become useless because of the provisions of a finally adopted plan, compensation for the cost of the projects and a refund of fees can be requested (art. 115.7). A licence that has already been issued and extended by law is not affected by the suspension (art. 189.4).
Example: the rules for housing changed
Since 1 January 2026, under art. 57.3 Llei d'urbanisme as amended by Llei 11/2025, the mandatory share of protected housing increased: in sòl urbanitzable (developable land) from 40% to 50% of the residential floor area of the development, in sòl urbà no consolidat (non-consolidated urban land) from 30% to 40%. General plans approved provisionalmente (provisionally) before 1 January 2026 and plan amendments approved inicialmente (initially) before that date do not apply the new shares for two years (Associació Catalana de Municipis overview). A buyer who had calculated the area on the old share ended up with a different model. A similar topic for Barcelona is in the article on the 30% quota.
What this does to the price: a worked example
The price of a plot is a residual: revenue minus costs minus profit. So it falls together with the permitted floor area. Worked example, not a forecast: we take the model from the article on development economics (20% margin on cost, a plot of about 1.2 M€ at 1,000 m²). The calculation: the plot price equals revenue divided by 1.2, minus the other costs, including ITP and the notary; the project and insurance (250,000 €) do not depend on the area, and the other items are proportional to it.
| Permitted floor area | Residual plot price | Change |
|---|---|---|
| 100% | about 1.2 M€ | 0% |
| 90% | about 1.059 M€ | −12% |
| 75% | about 847,000 € | −29% |
| 50% | about 491,000 € | −59% |
Cutting the area by a quarter takes away more than a quarter of the price. Fixed costs (project, licences) do not shrink with the area.
How to assess the risk before buying
- Determine the plot's stage using the table above.
- Check whether there is an aprobación inicial of new rules or a suspension decision in the plot's area. Plans are public, and the ayuntamiento issues a certificate of the plot's planning regime within a month of the request (art. 103 Llei d'urbanisme).
- Ask an abogado (lawyer) and an arquitecto what part of the price depends on parameters that could change.
- Calculate a scenario with a reduced area, as in the table above.
- Put the risk into the contract: a condition on the licence or the plan in an option to buy. How to check the plan before an offer is explained in the article on the planning check.
Who this approach does not suit
It does not suit anyone who wants to be fully protected against the risk: no stage gives full protection, and compensation covers the loss but not the project. It does not suit someone unwilling to read plan documents either: the assessment of the stage rests on them. An investor in that position is better off with a plot that has a licence, as in the article on the price difference. The assumptions behind the calculations are described in the methodology.
Questions and answers
Can the ayuntamiento change the plan after I have bought a plot?
Yes. A plan can be changed, and the law gives no right to compensation merely because of that (art. 6 Llei d'urbanisme). Compensation depends on the plot's stage.
When is compensation due for a plan change?
For example, when the change alters the urbanisation conditions before the planned deadlines expire or ends the effect of an issued licence (art. 48 RDLeg 7/2015). A specific case is assessed by an abogado.
How can I tell that a plan is about to change?
Decisions to suspend the issuing of licences are published in the official gazette with a map of the area (art. 73.3 Llei d'urbanisme), and plans are public and available in the Registre urbanístic de Catalunya (art. 103).
Does a suspension affect a licence already issued?
A licence extended by law is not affected by a suspension (art. 189.4). If the plan changes after a licence is issued, compensation under art. 48 RDLeg 7/2015 may be possible.
