Homes made from shipping containers are becoming increasingly popular thanks to their low cost, sustainability and quick build time. However, despite their innovative design, the legal and bureaucratic procedures are the same as for any traditional home. If you're planning to build a container home, here are the steps you'll need to follow to obtain planning permission in Spain.
1. Consult local planning regulations
Before purchasing a container or starting the design of your home, it’s essential to contact the town hall of the municipality where you plan to build. Each local authority has its own planning and building regulations, which dictate whether a property can be constructed on a particular plot of land and under what conditions. Key factors to consider include:
- Land classification (urban, rural, developable, etc.)
- Minimum setbacks and maximum occupancy
- Permitted heights
- Aesthetics or integration with the environment
Furthermore, some towns and cities do not yet specifically consider container homes, so it's a good idea to clarify this in writing.
2. Hire a competent technician
You’ll need a certified architect or technical architect to draw up the basic and final plans for the home. Although it's a container, it qualifies as a habitable structure and must comply with the Technical Building Code (CTE in Spanish), along with regulations concerning habitability, structural safety, thermal insulation and energy efficiency.
3. Apply for planning permission
Once you have the project approved, you’ll need to apply for planning permission or a major works permit from the relevant council. The application must include:
- Basic and detailed project
- Health and safety study
- Justification of compliance with the technical building code
- Payment of fees and taxes (such as ICIO, Tax on Construction, Installations and Works)
The time it takes for the building permit to be granted can vary, but it can range from a few weeks to several months.
4. Inspections during the construction
Once the permit is granted, construction can begin. The local council may carry out inspections during the works to ensure compliance with the approved plans. If any significant changes are made, a revised project must be submitted for approval.
5. Final works certificate and first occupancy permit
Once construction is complete, the architect will issue the final works certificate. With this document, you can apply for the first occupancy permit or certificate of habitation, which confirms that the property meets legal standards for occupancy. This certificate is essential for connecting utilities such as water, electricity and gas.
6. Register the home on the Land Registry
Finally, once all the necessary documentation is in place, you can register the property with the Land Registry and the Cadastre as a single-family dwelling. Even though it was built using a shipping container, the legalisation process is the same as for a conventional home.
