Types of Building Permits in Spain

From simple notifications to full planning permission—understand which type you need for your project.

Comunicación Previa

Prior Communication

Simple notification to the town hall for very minor works. Allows work to begin immediately after submission.

Examples:

Internal paintingLike-for-like fixture replacementsMinor garden work
Immediate (after filing)
€20-100

Declaración Responsable

Responsible Declaration

Self-declaration that work complies with regulations. More formal than comunicación but faster than full permits.

Examples:

Solar panel installation <10kWAC unit installationWindow/door replacement (same size)
Immediate to 1 week
€50-200

Licencia de Obra Menor

Minor Works Permit

Required for interior renovations that don't affect structure. Most common permit for home improvements.

Examples:

Bathroom renovationKitchen refitNon-structural internal wallsFlooring replacement
1-4 weeks
€150-500 + ~4% ICIO tax

Licencia de Obra Mayor

Major Works Permit

Full planning permission for structural works. Requires architect/engineer plans and formal approval.

Examples:

ExtensionsNew buildsStructural changesPool constructionRoof changes
2-6+ months
€500-5,000+ + ICIO tax

Important: ICIO Tax

Most permit types require payment of ICIO (Impuesto sobre Construcciones, Instalaciones y Obras)—typically 3-4% of the declared project budget. This is a local construction tax paid to your municipality, separate from the permit fee itself. Factor this into your renovation budget.

Pro Tip: Use a Gestor

A gestor (administrative agent) can handle permit applications on your behalf for €150-500. They know local procedures, can expedite processing, and ensure paperwork is correct first time.

FAQs

Frequently Asked Questions

Common questions about building permits and certificates in Spain

A Boletín Eléctrico (or Certificado de Instalación Eléctrica - CIE) is an official certificate issued by a registered electrician confirming your electrical installation meets Spanish safety standards. It's legally required for new installations, major modifications, connecting utilities, and selling or renting property. The certificate is valid for 20 years and costs €180-360.
Yes, usually an Obra Menor (minor works permit) is required for bathroom renovations in Spain. This applies even if you're not moving plumbing or making structural changes. The permit involves notifying your local town hall and paying a small tax (typically 4% of the project budget). Processing takes 1-4 weeks depending on your municipality.
Obra Mayor (major works) covers structural modifications, extensions, new builds, and significant alterations requiring architectural plans and formal approval—typically 2-6+ months to obtain. Obra Menor (minor works) covers non-structural interior changes like bathroom/kitchen refits, typically requiring only notification and costing less, with 1-4 week processing times.
For Obra Menor (minor works): 1-4 weeks on average, though some municipalities have express services within days. For Obra Mayor (major works): 2-6 months or longer, depending on complexity and municipality backlog. Marbella and popular coastal towns may have longer wait times due to volume.
No, this is risky and potentially illegal. Starting without permits can result in stop-work orders, fines (up to 10x the permit cost), demolition orders for unauthorized construction, difficulty selling the property, and insurance invalidation. Some minor works have declaración responsable (self-declaration) allowing immediate start, but verify with your town hall first.
The Licencia de Primera Ocupación (LPO) or Cédula de Habitabilidad certifies a property is safe and legal to occupy. It's required for new builds and major renovations. Without it, you cannot legally connect utilities or register residents. The process involves final inspections and costs €500-2,000+.
Yes, but the process has been simplified. For self-consumption installations under 10kW, most municipalities require only a comunicación previa or declaración responsable (self-declaration) rather than a full permit. Larger installations or grid-connected systems may need more extensive approval. Legalisation with the electricity company is also required.
