Converting a commercial space into a residential property in Barcelona is entirely possible as long as urban planning regulations and habitability requirements are met. The process requires the involvement of an architect, obtaining permits from the City Council, and carrying out adaptation works.

At Kaitek Arquitectura, architects in Barcelona, we specialize in projects converting commercial spaces into residential properties, offering a comprehensive service from feasibility studies to final registration at the Property Registry while complying with all legal requirements.

Why convert a commercial space into a residence?

More and more people are looking for housing alternatives in central areas of Barcelona, where the supply of apartments is limited and expensive.

Converting a commercial space into a residence is not only a more affordable option but also allows for designing unique and modern spaces tailored to your needs. Additionally, it is an attractive investment in a constantly moving real estate market.

Steps to convert a commercial space into a residential property in Barcelona

The conversion process involves a series of technical and legal procedures that must be professionally managed. The main steps are:

1.Urban planning consultation

First, verify that the Barcelona Urban Plan allows the change of use in your area. Without this step, the project cannot begin.

2.Feasibility study and technical project

An architect analyzes the space to determine if it meets habitability requirements: lighting, ventilation, accessibility, minimum area, etc.
At Kaitek Arquitectura, we develop a complete technical project, including plans and the layout of the future residence.

3. Building permit

The project is submitted to the City Council to obtain the corresponding permit. If the building is heritage-protected, a favorable report from the Heritage
Department must be obtained first.

4. Adaptation works

In this phase, the necessary interventions are carried out:

  • Thermal and acoustic insulation
  • Water, sanitation, and electrical installations
  • Ventilation and natural lighting
  • Smoke outlets for kitchen and bathroom
  • Radon protection if the space is on the ground floor

5. First occupancy permit

Once the works are completed, the City Council issues the permit that allows the property to be inhabited.

6. Registering the change of use

The final step is to go to a notary to formalize the change of use and register the property at the Property Registry. The land registry can also be updated accordingly.

Key technical requirements

For a commercial space to be converted into a residence, it must meet certain minimum conditions:

  • Exterior façade: must comply with the minimum façade requirements established by the habitability decree and municipal regulations

  • Usable area: must meet the minimum required by law

  • Natural lighting: windows must represent at least 1/8 of the usable area of each room

  • Accessibility and safety: compliance with fire and architectural barrier regulations
