House in Alella or Teià: slope, urbanización and fire strip

Buying a house in Alella or Teià means buying a plot on a slope, often in an urbanización (a private residential estate) next to the forest, not a flat by the sea. In the 2021 census, half of the main homes in Alella and 46% in Teià had more than 120 m² of usable floor area, against 18% on average across the Maresme (Idescat, Alella). So before the price, the road, the terrain, the fire-protection strip and the status of the urbanización are checked.

How Alella and Teià differ from the coastal Maresme

These are two small Maresme municipalities higher up the slope, where the market consists mostly of detached houses. The coastal towns are strung along the Rodalies R1 line, which runs along the shore (Rodalies, R1), while the centre of Alella sits at 90 m above sea level and Teià at 128 m. From here you usually have to drive to the train.

The figures for Teià come from the Idescat municipal profile. Two practical conclusions follow from the table. The houses are large, and upkeep of the plot, the roof and the systems falls on the owner. Fewer than one household in six rents, so the rental market is thin and there are few similar houses to compare with, which makes the price of a single house harder to verify than the price of a flat in the city.

What the forest-fire law requires of an urbanización

If an urbanización stands in a forest or within a 500 m belt around it, the Catalan Ley 5/2003 on forest-fire prevention in urbanizaciones applies to it (art. 1). Which urbanizaciones and houses fall under the law is decided by the ayuntamiento (town council) in a delimitation plan (art. 2).

The duties are listed in art. 3: a protection strip at least 25 m wide around the urbanización, free of dry vegetation and with thinned trees; the same condition for plots inside the strip; a self-protection plan; a network of hydrants and private roads kept clear of dry grass. Under art. 4 they are carried out by the urbanización's comunidad de propietarios (owners' association) or by the entidad urbanística colaboradora (a collaborating urban-planning body that maintains the estate). Where there is no such body, the plot owners are jointly liable. For a stand-alone house the duties rest with its owner, and if the work is not done, the municipality does it and may charge a fee.

For the buyer these are direct costs and a question for the seller: who clears the strip, what it cost last year, whether a self-protection plan exists. How fire risk and storm-fed rieras (seasonal watercourses) affect house insurance is covered in the article on villa risks.

Who maintains the roads and utilities of an urbanización

It depends on whether the town hall has taken the urbanización over. If the municipality has accepted the roads, lighting and sewers, it maintains them. If not, the residents pay through the dues of the entidad urbanística or the community, and future repairs fall on them too.

Old settlements that arose in 1956–1981 with unfinished urbanisation are under a special regime (disposición adicional vigesimoquinta Llei d'urbanisme). How dues and voting work in an entidad urbanística is described in the article on gated urbanizaciones. How the logic differs in the coastal towns, with their coastal law and rieras, is shown in the overview of the Maresme and Garraf coast.

How to check a house on a slope before you make an offer

The order of checks runs from what is most expensive to fix. Finishes can be changed; the slope, the road and the status of the urbanización cannot.

1. The road. Drive the route to work and school twice: on a weekday at rush hour and at the weekend. On the narrow, steep streets of an urbanización this is a daily routine, not a detail of the viewing.
2. The terrain. Inspect terraces and retaining walls: cracks, tilt, traces of water. After a downpour the water must leave the plot, not run into the garage or basement.
3. Documents versus reality. Match extensions, enclosed terraces and the pool against the licences and the description in the registry. What to do with a structure built without a licence is covered in a separate article.
4. Annual costs. Ask for 12 months of electricity, heating and water bills, the IBI (local property tax) receipt and the urbanización dues, including clearing the fire strip.
5. Technical report. The roof, facade, heating and systems of a private house are entirely the owner's, so the inspection is done by an arquitecto or an aparejador (a licensed architect or a building surveyor), not by the seller.
6. The price. There are few deals on similar houses, so the price is checked against closed transactions in Alella, Teià and neighbouring municipalities, adjusted for the plot and the works.

Who a house in Alella or Teià does not suit

These towns do not suit someone who wants to live without a car and commute to central Barcelona every day at rush hour. They also do not suit a buyer counting on a quick resale: the market is thin, each house differs in plot and condition, and the time to sell is hard to predict.

The logic is also weak for a buy-to-let: about 16% of households rent, and an income calculation rests on few comparable properties. And finally, someone not ready to maintain a garden, terraces and a protection strip is better off looking at a flat with a terrace in a coastal town.
