Barcelona is famous for its historic architecture, characterful apartments and buildings that reflect the city’s unique identity. High ceilings, original mosaic floors, balconies and traditional Catalan features can make older properties especially attractive to buyers.
However, buying an older apartment in Barcelona requires more than simply evaluating the apartment itself. The condition of the entire building, potential renovation costs, technical inspections and community expenses can all affect the real cost of your investment.
Before making a decision, here are some of the most important things to check.
1. Check the ITE of the Building
One of the first documents worth reviewing when buying an older apartment in Barcelona is the building’s ITE (Inspecció Tècnica de l’Edifici).
The ITE is a technical inspection designed to assess the general condition of certain residential buildings. It can identify issues affecting elements such as the façade, roof, structure and communal areas.
For a potential buyer, the ITE can provide useful information about the condition of the building and whether repairs have been identified.
If problems appear in the inspection, it is important to understand:
- What deficiencies were identified?
- Have the necessary repairs already been completed?
- Are additional works planned?
- Could owners face additional costs?
Checking this information before purchasing can help you understand potential future expenses.
2. Ask About Upcoming Building Renovations
An apartment may look perfectly renovated inside while the building itself requires significant work.
Older Barcelona buildings can require maintenance or renovation of façades, roofs, lifts, staircases, plumbing or other communal elements.
Before purchasing, ask whether the community of owners has approved or discussed any major works.
This is particularly important because large building renovations can result in additional payments for property owners.
3. Find Out Whether There Are Any Derramas
A derrama is an extraordinary payment agreed by the community of owners to cover expenses that cannot be sufficiently covered by the regular community budget.
For example, a derrama could be introduced to finance repairs to a façade, roof, lift or another communal part of the building.
When considering a property, ask whether there are any existing or recently approved derramas and clarify how they are being paid.
This can make a significant difference when calculating the actual cost of purchasing the property.

4. Review the Community Fees
Regular community fees are another expense buyers should consider.
These contributions are used to maintain the communal areas and services of the building. The amount can vary depending on factors such as whether the property has a lift, concierge, communal spaces or other shared services.
Before buying, check the current community fee and what it covers.
It is also useful to review recent decisions made by the community of owners, as these may reveal planned improvements or expenses that could affect future costs.
5. Check the Energy Performance Certificate
The Energy Performance Certificate (EPC) provides information about a property’s energy efficiency.
Properties are rated on a scale from A to G, with A representing higher energy efficiency and G representing lower efficiency.
Older properties may have less efficient windows, insulation or heating and cooling systems. However, the age of a building alone does not determine its energy performance, particularly if the apartment or building has already undergone improvements.
Reviewing the EPC can give buyers a clearer idea of the property’s current energy performance and possible areas for improvement.
6. Inspect the Property Beyond Its Appearance
Original details are often part of the appeal of Barcelona’s older apartments, but buyers should also consider the condition of the less visible elements.
Pay attention to:
- Electrical installations
- Plumbing
- Windows and insulation
- Signs of humidity or water damage
- Heating and air-conditioning systems
- Walls, ceilings and flooring
If you are considering a property that requires substantial renovation, obtaining professional technical advice before completing the purchase can provide a clearer understanding of the work that may be required.
7. Understand the Renovation Possibilities
Older apartments often offer excellent opportunities for renovation, especially properties with large rooms and flexible layouts.
However, not every modification is necessarily possible.
Structural walls, protected architectural elements, building regulations and community rules can affect what can be changed.
If your purchase depends on a specific renovation — such as creating an additional bedroom, opening the kitchen or changing the internal distribution — it is worth checking whether the project is technically and legally feasible before committing to the property.
8. Review the Building Documentation
The apartment itself is only part of the purchase.
Relevant documentation relating to the property and building can help provide a more complete picture of what you are buying.
Depending on the property, buyers may want to review documents relating to:
- ITE and building condition
- Community fees
- Approved or pending derramas
- Energy certification
- Previous or planned building works
- Community decisions relevant to the property
Understanding these documents can help reduce unexpected surprises after the purchase.
9. Consider the Building as Part of Your Investment
When buying an older apartment in Barcelona, it is easy to focus on the interior: the layout, natural light, balcony, original floors or renovation potential.
But the condition and management of the building are equally important.
A beautiful apartment inside a building requiring extensive communal repairs could involve expenses that are not immediately obvious during a viewing.
For this reason, evaluating both the apartment and the building as a whole is an important part of the buying process.
Final Thoughts
Older apartments are an important part of Barcelona’s real estate market and can offer character, distinctive architecture and excellent renovation potential.
At the same time, purchasing one requires careful research.
Checking the ITE, community fees, derramas, energy certificate, building condition and renovation possibilities can give you a much clearer understanding of the property before making your decision.
