When buying property in Spain, surveys are not legally mandatory in most cases. Unlike some countries, there is no requirement for a full structural survey.
However, “not mandatory” does not mean “not important.” Surveys and technical reports are key tools for risk management, especially for older, rural, or renovated properties.
Understanding the types of surveys, who prepares them, and when they are relevant can save buyers from costly surprises.
Types of Surveys You Can Expect
In Spain, surveys generally fall into three categories:
- Technical or Structural Survey
- Planning & Legal Conformity Checks
- Energy Performance Certification (EPC / Certificado Energético)
Each serves a distinct purpose and carries a different level of legal and practical weight.
1. Technical / Structural Survey
Purpose:
A detailed inspection of the physical condition of the property.
Prepared by:
A qualified architect (arquitecto) or technical architect (arquitecto técnico).
What it covers:
- Structural condition (walls, beams, foundations)
- Roofs, terraces, balconies
- Damp, cracks, subsidence, or other visible defects
- Plumbing, electrics, and installations (visual inspection)
- Estimated repair or maintenance costs
When it’s most relevant:
- Older properties
- Villas or rural homes
- Properties intended for renovation
- Properties showing visible defects
Key point:
This survey is optional but strongly recommended. Defects discovered after purchase are usually the buyer’s responsibility.
2. Planning & Conformity Surveys
Purpose:
Confirms that the property is legally compliant.
Also called:
- Certificate of Conformity
- Urban Planning Report
Prepared by:
Architects or engineers, sometimes submitted to the Town Hall.
What it checks:
- Property matches planning permissions
- Aligns with Cadastre and Land Registry records
- Can obtain a Licencia de Primera Ocupación (LPO) or AFO status
When it matters:
- Properties without an LPO
- Rural properties or land plots
- Extensions, alterations, or renovations
- Mortgage or resale planning
Key point:
This survey focuses on legal risk, not physical condition.
3. Energy Performance Certificate (EPC / Certificado Energético)
Purpose:
Measures the property’s energy efficiency.
Required by law:
- Mandatory for selling or renting property in Spain.
What it assesses:
- Energy efficiency rating (A–G)
- CO₂ emissions
- Insulation, windows, heating and cooling systems
Who issues it:
A certified technician registered with the regional authority.
Why it matters:
- Required before marketing the property
- Impacts ongoing running costs
- Increasingly relevant for future regulations and renovations
How Surveys Fit Into the Buying Process
- Surveys are typically conducted after the reserva (reservation agreement).
- They are used to verify legal compliance and identify physical issues before signing a private purchase contract.
- New-build properties usually include a 10-year structural guarantee, while older homes do not.
- Technical certificates for water and electricity (boletines / potencia) may also be required.
- Seasonal considerations: Buying in summer may hide winter-related problems (e.g., damp or heating issues) and vice versa.
- Future planning: Check for expansion possibilities (extensions, pool legality, community restrictions).
- Cross-check survey findings with the Nota Simple and Escritura to confirm what was actually built.
Summary & Key Takeaways
- Surveys are not legally mandatory in Spain, but strongly advised, particularly for older, rural, or renovation properties.
- Use a combination of technical/structural surveys, planning/conformity checks, and energy certificates to reduce risk.
- Always work with qualified professionals: architects, technical architects, or certified energy assessors.
- Check seasonal issues and verify documentation against official records.
- Ensure any new-build property has the LPO and 10-year structural insurance.
Properly conducted surveys protect your investment, reduce unforeseen costs, and provide peace of mind when buying property in Spain.
