What you can build on your plot: planning law in plain English

You own a plot — inherited, bought years ago or one you're thinking of buying — and the big question is: what can I build here? The answer isn't in what the neighbour tells you nor in what "has always been done": it's in your municipality's urban planning. We translate the three concepts that decide everything.

Important note: planning is decided by each town hall and changes with each plan. This is a general, educational explanation; before buying land or commissioning a project, consult the cédula urbanística (the urban planning certificate) and a technician.

1. Clasificación: what type of land it is

This is the first question and the most decisive. Land is classified, broadly, as:

• Suelo urbano (urban land): the consolidated town centres, with streets, electricity, water and drainage. This is where you can normally build.
• Suelo urbanizable (land earmarked for development): today it's countryside, but the plan foresees it one day becoming town. Building here depends on the sector being developed: it can take years.
• Suelo no urbanizable (non-developable, rustic land): protected for its agricultural, forestry or landscape values, or simply because the plan doesn't want it to grow. Building here is very limited: in general, only constructions tied to farming use and with demanding authorisations.

Much disappointment comes from here: a cheap plot on rustic land isn't a bargain if what you want is a house. The low price is usually the warning.

Urban land isn't all the same either

Even within urban land there are nuances. A building plot on a consolidated street, with pavements and services passing the door, isn't the same as a plot in a half-developed sector where the streets are half finished. In the second case, there may be pending urbanisation charges: costs of finishing the streets, lighting or drainage passed on to owners. Always ask how far the urbanisation has got and whether there are pending levies: they're part of the plot's real price, even if they don't appear in the advert.

What to ask at the town hall

Before committing, a visit (or a call) to the planning department with the referencia catastral (the cadastral reference) in hand resolves most doubts. Ask:

• What clasificación (land classification) and calificación (permitted use) does this plot have?
• Is there any plan in the pipeline that could change its situation?
• Does the plot have a pending licence or file, or any recorded infringement?
• Do the services (water, electricity, drainage, access) reach it?

Note down the names of who serves you and, whenever you can, ask for it to be given to you in writing: verbally everyone is optimistic. The document that sums all this up is the cédula urbanística.

2. Calificación: what it can be used for

Within urban land, each block has an assigned use: residential, commercial, industrial, facilities (schools, parks)... You can't put up a home where the plan only allows industry, nor a block of flats where only detached houses fit.

3. The parameters: how much and how

Even if the use fits, the plan puts numbers on the construction:

• Edificabilidad (total buildable floor area): how many square metres you can build in total on your plot.
• Ocupación (site coverage): what part of the plot the building can stand on (the rest stays free: garden, patio).
• Height and storeys: how many floors upwards.
• Setbacks and boundaries: how far from the edges and the street the house has to sit.

Two neighbouring plots of the same size can allow very different houses according to these parameters. That's why "my plot is 800 m²" says almost nothing on its own.

Where it's checked (don't trust word of mouth)

All this is written in your town hall's Plan General (the municipal master plan — each municipality has its own, with its own name). But nobody expects you to read a thousand-page plan: that's what the cédula urbanística is for, a municipal document that sums up the planning situation of a specific plot. Request it before buying land: it's cheap and avoids expensive grief.

The classic mistakes

1. Buying because "everyone's built here". What was done without a licence decades ago gives you no rights today; on the contrary, it can bring you a file.
2. Confusing plot metres with buildable metres. See point 3.
3. Not checking whether there's a plan in the pipeline. A new plan can change your land's classification, for better or worse.
4. Commissioning the project before checking the planning. First what can be done; then, how.

Golden rule: in land, cheap without checking the planning comes expensive. The cédula urbanística first; the dream, after.
