General Builders in Spain - What Expats Need to Know

What a general builder in Spain actually does and what they do not

The term general builder covers a wide range of competence and experience on the Costa del Sol. At one end of the spectrum are large registered construction companies with architects, project managers, and specialist subcontractors handling every aspect of a build. At the other end are individuals with a van, some tools, and the confidence to quote for anything regardless of whether they can deliver it.

Understanding what a general builder should and should not be doing on your project and what qualifications and registrations to look for is the starting point for hiring the right one.

What qualifications should a Spanish general builder hold

Spain does not have a single mandatory registration for general builders in the way that electricians and gas engineers must be registered with their regional industrial authority. However, for significant structural work, the project should involve a registered arquitecto técnico or aparejador overseeing the build. For any project requiring a licencia de obras mayor, a registered architect must produce the proyecto de obras before the ayuntamiento will accept the planning application.

What you should ask any general builder to provide:

• Company NIF - confirms they are registered as a legitimate business with the Agencia Tributaria. Search the NIF at agenciatributaria.gob.es to verify it is active.
• Seguro de responsabilidad civil - liability insurance covering damage to your property and neighbouring properties during the works. Ask for the certificate and check the expiry date.
• References from comparable projects - not just names but contacts you can actually speak to. Ask specifically about projects similar in scope to yours completed in the last twelve months.
• Details of subcontractors - a general builder who subcontracts electrical, plumbing, or gas work must use registered specialists for those trades. Ask who they use and verify the subcontractors hold the correct registrations independently.

What general builders cost in Spain

Day rates for general builders on the Costa del Sol in 2026 range from €150 to €280 per day depending on experience, specialisation, and location. Marbella and the western Costa del Sol sit at the higher end. The Axarquía and inland areas are generally more competitive.

For project-based pricing, the key benchmarks are:

• Reforma cosmética - cosmetic refresh of a two-bedroom apartment: €8,000 to €20,000
• Reforma parcial - partial renovation of a two-bedroom apartment: €20,000 to €60,000
• Reforma integral - full renovation: €600 to €1,200 per square metre depending on specification

Always get a minimum of three written quotes. Always confirm whether IVA at 21 percent is included. Always ask for labour and materials broken out separately.
