Building Permits and Urban Planning Liability in Spain: TRLSRU and Urban Law (2026)

Building Permit Regime in Spain

Urban planning licences (licencias urbanísticas) are municipal administrative authorisations required for construction, extension, modification or demolition works. Their legal framework is governed by:

• Royal Legislative Decree 7/2015 (TRLSRU): national legislation on land use and urban regeneration
• Regional legislation: LOUA (Andalusia), LSCVK (Basque Country), LUCyL (Castile and León), etc.
• PGOU (General Urban Development Plan) and municipal planning instruments: permitted uses, buildability ratios, height limits, building lines

Types of Municipal Intervention

1. Major Works Permit (Licencia de Obras Mayor): Prior Authorisation

Major works (new construction, structural extensions, demolition, change of use) require prior authorisation. Administrative silence is negative (Art. 24.1 LPAC: Law on Common Administrative Procedure): planning permission cannot be obtained through positive administrative silence.

Documentation required for a major works permit: technical project signed by a licensed architect with professional visa (visado colegial), descriptive report, material execution budget (presupuesto de ejecución material, PEM), health and safety study.

Resolution period: typically 3 months (varies by Autonomous Community). The local authority may suspend the process pending correction of deficiencies by the developer.

2. Prior Notification and Responsible Declaration (Comunicación Previa and Declaración Responsable) (Law 2/2011 + 2013 Reform)

Law 20/2013 on Guaranteeing Market Unity (Ley de Garantía de la Unidad de Mercado) promoted the replacement of formal permits with prior notification (comunicación previa) or a responsible declaration (declaración responsable) for minor works (small-scale refurbishments with no structural impact) and certain activities. Effect: works may commence immediately without awaiting a formal decisión, under the declarant's own responsibility. The local authority retains the power to carry out subsequent inspections.

3. Works Carried Out Without a Permit or Notification

Works carried out without any enabling title are unlawful and subject to proceedings for restoration of planning legality (expediente de restablecimiento de la legalidad).

Planning Infringements and Sanctioning Regime

Types of Infringements (TRLSRU + Regional Legislation)

• Very serious: unlawful plot subdivision on protected non-developable land, works in specially protected areas, failure to comply with demolition orders
• Serious: works without a permit on non-developable land, breach of building regulations regarding structure or volume
• Minor: non-compliance with permit conditions without substantial alteration

Limitation periods for infringements (TRLSRU Art. 36.1 and regional legislation):

• Very serious: 4 years
• Serious: 2 years (or 4 years in protected areas)
• Minor: 1 year
• Works on non-developable rural land: some Autonomous Communities provide for imprescriptibility (Andalusia, Art. 185 LOUA for non-developable land)

Sanctions

Fines vary by Autonomous Community. The Andalusian LOUA provides for fines of up to 100% of the value of the unlawful works for very serious infringements, plus mandatory demolition.

Restoration of Planning Legality

Independently of any sanction, the local authority may (and must) order restoration of legality:

1. Suspensión of works in progress
2. Demolition of unlawfully constructed elements (where the works cannot be regularised)
3. Regularisation (legalización) where the works are compatible with applicable planning regulations (the developer applies for retrospective authorisation)

Time limit for restoration action:

• Urban land: 4 years from completion of the works (TRLSRU Art. 36.2) ( once this period has elapsed, the works acquire out-of-compliance status (situación de fuera de ordenación) ) demolition can no longer be ordered, but extensions and certain types of rehabilitation are also prohibited
• Protected non-developable land: imprescriptible in many Autonomous Communities (Andalusia, Madrid, Valencia)

Out-of-compliance status (fuera de ordenación, Art. 34 TRLSRU): existing buildings that pre-date new planning instruments which render them non-compliant retain their consolidated status but may not be extended or granted a change of use.

Criminal Liability in Planning Matters (Arts. 319–320 of the Criminal Code)

The Código Penal (Spanish Criminal Code) specifically criminalises planning offences:

Art. 319 CP: Unlawful Works

• Art. 319.1 CP: Construction on specially protected non-developable land, green spaces, drovers' roads (vías pecuarias), protected coastline or protected natural areas, 1 to 3 years' imprisonment, a fine of 12 to 24 monthly payments, and demolition
• Art. 319.2 CP: Construction without a permit on ordinary non-developable land, or where the applicable regulatory requirements are wholly or substantially disregarded, 6 months to 3 years' imprisonment plus a fine

Court-ordered demolition: The Second Chamber of the Supreme Court (Sala 2ª del Tribunal Supremo, STS 363/2006) established that a criminal conviction must as a general rule include a demolition order, unless this would be disproportionate having regard to the circumstances of the case.

Art. 320 CP: Public Official Issuing Favourable Reports or Granting Unlawful Permits

A civil servant or public authority who issues favourable reports or grants permits in breach of planning regulations is liable to 1 to 3 years' imprisonment and special disqualification for 7 to 10 years. This is the most serious offence applicable to municipal technical staff.

Conclusion

A planning lawyer must be conversant with both administrative sanctioning law (limitation periods, restoration proceedings, regularisation) and the criminal implications of Art. 319 CP. The key defensive strategy in restoration proceedings is to demonstrate that the works are time-barred or capable of regularisation. In criminal proceedings, the primary defence is absence of a criminal offence (atipicidad), that is, arguing the works were carried out on developable land and constitute a mere administrative infringement.
