The transformation of commercial premises into residential housing has become a growing trend in Barcelona, driven by the need to expand the housing supply and revitalize underused urban spaces.
This process, known as the change of use from commercial premises to housing, involves a series of technical, legal, and economic considerations that must be carefully evaluated.
Why Consider Changing a Commercial Premises into Housing in Barcelona?
Barcelona is a dynamic city with high housing demand, especially in central areas. Converting disused commercial premises into residential spaces offers a practical solution to increase housing availability without expanding the city’s urban boundaries.
Additionally, this practice contributes to neighborhood revitalization, improves safety, and promotes local economic activity.
Technical and Legal Aspects to Consider
Transforming a commercial property into a dwelling requires compliance with several requirements set out in urban planning regulations and the Código Técnico de la Edificación (CTE – Spanish Building Code). The key aspects are as follows:
1. Land Classification
It is essential that the property is located on urban land and that local regulations allow residential use in that area. Each municipality has its own planning rules, so consulting local ordinances is a must.
2. Authorization from the Homeowners’ Association
If the property is part of a community building, it is necessary to verify whether the community bylaws allow the change of use. Although formal approval is not always mandatory, it is highly recommended to avoid potential disputes.
3. Compliance with the Spanish Building Code (CTE)
The converted dwelling must meet the habitability and safety standards established by the CTE, including:
- Minimum surface area: The home must have sufficient usable area to ensure adequate living space.
- Ceiling height: A minimum height of 2.5 meters is required in at least 70% of the habitable area.
- Natural ventilation and lighting: Main rooms must have adequate ventilation and natural light.
- Acoustic and thermal insulation: Proper insulation is crucial to ensure comfort for future residents.
4. Housing Density Limitations
Certain areas have maximum housing density limits (number of dwellings per hectare). It is essential to ensure that the conversion does not exceed the limits established by local urban planning regulations.
5. Obtaining the Occupancy Certificate
The Occupancy Certificate certifies that the dwelling meets the minimum habitability standards. It is indispensable for legalizing the conversion and for using the property as a residence.
Costs Associated with the Change of Use
The budget required to convert a commercial property into housing can vary greatly depending on several factors such as location, current condition of the premises, and the extent of the renovation work.
1. Municipal Licenses and Fees
Obtaining the necessary permits involves paying municipal fees that typically range between €400 and €1,500, depending on the municipality and project specifics.
2. Technical Project and Professional Fees
The cost of hiring an architect to draft the technical project usually ranges between €1,500 and €2,500, depending on the complexity of the renovation and total surface area.
3. Renovation Costs
Renovation expenses generally range from €400 to €900 per square meter, depending on material quality and the scale of the work required.
4. Taxes and Other Administrative Expenses
It is important to consider the Construction, Installations, and Works Tax (ICIO), which is calculated as a percentage of the material execution budget. Additionally, notary and land registry costs must be included for updating the property deed and registration.
Steps to Carry Out the Change of Use
Here are the key stages for converting a commercial property into a residential dwelling:
1. Feasibility Study
Before beginning any formal process, it is essential to conduct a feasibility study to evaluate whether the premises can be converted into a home. This includes urban, technical, and financial analyses.
2. Preparation of the Technical Project
An architect must prepare a detailed project that includes all necessary modifications to ensure the new home complies with current building and habitability regulations.
3. Application for Licenses and Permits
Once the project is ready, the next step is to apply for the required building and change-of-use licenses at the corresponding city council.
Processing time varies by municipality but generally takes 3 to 4 months.
