Buying land in Portugal: what to check before you pay
Many people who move to Portugal end up looking at a plot instead of a house: land with a view, a price that seems low and a plan to build. The price is often low for a reason. Whether you can build on a plot is decided by the municipality's plans, not by the seller or the listing.
Here is what to check, in this order, before you sign a promissory contract (CPCV) or pay a deposit.
1. Rústico or urbano: what the papers say
Every property in Portugal has a tax record, the caderneta predial, and a land-registry record. The caderneta says whether the plot is a rústico (rural) or an urbano property. For tax purposes, land for building (terreno para construção) is an urban property. A rústico plot is rural land: buying it gives you no right to build on it.
Two common surprises: a listing that says "building land" while the caderneta says rústico, and a rústico plot with an old ruin that the seller calls "approved for rebuilding" without a single document from the câmara to show for it.
How to read the tax record: the caderneta predial explained.
2. The land-registry certificate
Where: online through gov.pt (Predial Online) or at any land-registry office.
Cost online: €15. Valid for: 6 months.
You need: your NIF and the address of the property.
The certificate (certidão permanente) shows who is registered as the owner and what is registered against the plot, such as a mortgage (hipoteca) or an attachment (penhora). Check that the seller is the registered owner and that the area and description match the caderneta and what you see on the ground.
3. The municipal plan (PDM) and building capacity
Each municipality has a master plan, the PDM (Plano Diretor Municipal). It divides the land into zones and sets what may be built in each one: use, building index, height, distance to boundaries. Together this is the plot's building capacity (capacidade construtiva). Ask the câmara, or look on its website, for the PDM maps that cover your plot: the zoning map and the map of constraints.
4. RAN and REN: the two reserves that block building
RAN (Reserva Agrícola Nacional) protects farmland. By law, RAN land is for farming and is a no-build area. The law lists the exceptions: buildings for a working farm, a farmer's own permanent home, rural tourism linked to farming, and the owner's own home only when the owner proves economic hardship and owns no other home. Each exception needs a binding prior opinion from the regional RAN body.
REN (Reserva Ecológica Nacional) protects areas such as flood zones, steep slopes and coastal strips. In REN land, dividing into building lots, building and extending are banned, except for uses the law lists as compatible.
If any part of the plot is in RAN or REN, assume you cannot build there until the câmara tells you otherwise in writing.
5. Ask the câmara in writing: the PIP
The strongest check before buying is a request for prior information, the pedido de informação prévia (PIP). Anyone can file it, not only the owner. You ask the câmara whether a specific project is viable on that plot and under which conditions: constraints, building index, height, distances.
Answer due: 20 days, or 30 days for a detailed request (counted from the request, or from the last outside opinion when other bodies are consulted).
If favourable: it binds the câmara when it later decides on the building licence.
Not the owner? You identify the owner with a land-registry certificate, and the câmara informs the owner that you asked.
If the answer is unfavourable, the câmara has to say, where possible, how the project could be changed to comply. A favourable answer does not last forever, so ask the câmara how long it holds for your project.
A sensible order: the PIP first and the CPCV after, or a CPCV that makes the deal depend on a favourable PIP. Ask a lawyer to word that clause.
6. Taxes on buying land
IMT on a rústico plot: 5%.
IMT on a building plot (urban property): 6.5%.
Stamp duty (Imposto do Selo): 0.8%.
IMT is charged on the higher of the deed price and the property's tax value (VPT). The flat 7.5% IMT rate for non-resident buyers applies to urban property used only as housing, so a plot of land is taxed at the rates above. Estimate your full buying costs.
Checklist before you pay anything
- Caderneta predial: rústico or urbano, area, tax value.
- Land-registry certificate: registered owner, mortgages, attachments, matching area.
- PDM maps of the plot: zone, building index, constraints.
- RAN or REN on any part of the plot.
- A written PIP answer from the câmara, or a CPCV that depends on it.
- Road access, water, electricity and sewage: ask the câmara and the utility companies what connecting will cost.
- IMT of 5% or 6.5% plus 0.8% stamp duty in the budget.
