What are setbacks and why are they key if you are going to buy a plot of land in Spain?
“Set… what?”
If you are thinking of buying a plot of land in Spain to build your home, there is an urban planning concept that you should be aware of from the beginning: setbacks (retranqueos in Spanish).
And no, it’s not a minor detail. Ignoring them can result in fines, construction being halted or even the obligation to demolish part of the building.
What is a setback?
A setback is the minimum mandatory distance that must exist between a building (house, swimming pool, storage room, garage, etc.) and:
- The plot boundary.
- The public thoroughfare (street, road or public right of way)
- Adjacent plots
In Spain, you do not own 100% of the buildable land: urban planning regulations limit where and how you can build.
Setbacks from public roads: much more than an aesthetic issue
Setbacks from streets or roads not only serve an aesthetic function, but are also essential for safety and urban coexistence:
- Better visibility at crossings and access points
- Space for firefighters to operate (ladder trucks that must be deployed in case of fire)
- Access for special vehicles such as ambulances, police cars and delivery vans.
- Risk prevention, avoiding the fall of objects onto public roads or the spread of fire
If these are not respected, the City Council may refuse to grant a building permit and impose financial penalties.
Which buildings must comply with setbacks?
International buyers are often surprised to discover that it is not only the main dwelling that must comply with these regulations.
The following must also comply with setbacks:
- Swimming pools (yes, even swimming pools)
- Storage rooms and warehouses
- Garages
- Subsequent extensions and renovations
Each municipality sets its own minimum distances according to the General Urban Development Plan (PGOU).
Setbacks between neighbours: avoid legal disputes
In addition to public roads, there are also setbacks between private plots. Their purpose is to:
- Ensure natural light and ventilation
- Respecting rights of light and views
- Reduce the risk of fire spreading
If these rules are not respected, the neighbouring owner may take legal action, for example if a new building has a direct view of their swimming pool or home.
Buying a plot and building in Spain: seek advice before you start
A mistake at this stage can be very costly. To ensure legal security and peace of mind:
- Seek legal advice to find out about planning regulations
- Always hire an architect to correctly define the setbacks
