Essential checklist for buying a house to renovate in Barcelona

Buying a house to renovate in Barcelona can be an excellent opportunity to personalize your home, start your business or get a good investment. But this type of operation requires a very detailed and clear vision from the beginning. Many premises and properties look attractive at first glance, but hide problems that only an expert eye can detect.

If you are considering this option and you are a buyer with no experience in renovations or in the Barcelona market, here is a practical guide with the key points to review before buying.

1. General structural condition

Start with the basics: check if the structure of the property is in good condition. Cracks, persistent dampness, cracked ceilings or uneven floors can be signs of major problems. It is advisable to have a professional technical inspection to detect these issues before signing any commitments.

Real feasibility of reform

Not everything you imagine can be executed. Some walls may be load-bearing, or there may be limitations due to regulations or community bylaws. Before assuming that you will be able to redistribute spaces, open a kitchen or join rooms, you need to confirm if it is technically and legally feasible.

3. Facilities and energy efficiency

Many older properties retain obsolete electrical, plumbing or HVAC systems. Renovating them is necessary both for safety and to comply with current regulations. It is also advisable to check the thermal and acoustic insulation, as this has a direct impact on the comfort and energy consumption of the future home.

4. Legal Documentation

Before you buy, be sure to check:

  • Nota simple registral (to verify ownership and encumbrances)

  • Certificate of occupancy (in case of dwellings)

  • Energy certificate

  • Tax situation (IBI up to date, possible debts)

In the case of a building with the idea of a change of use, there are more requirements to be analyzed with a technician.

5. Approximate renovation budget

Although the purchase price may seem attractive, the renovation can considerably increase the total investment. It is essential to have a professional estimate adjusted to the state of the property and the type of renovation you wish to carry out, before closing the transaction.

6. Community and environment

Check if there are any pending assessments, approved works or limitations by the community. It is also important to assess the urban environment: are there green areas, public transportation, is it a growing area?

Conclusion: informed decision, secure investment

Buying to renovate is a smart option, but only if it is rigorously analyzed. A property with a good location but poor structural conditions or legal limitations can become a source of problems. The key is be well informed before you buy, not after.
