El Masnou: a flat by the marina, the R1 and what is bought separately
A compact town with a 1,054-berth port and a commuter train along the shore. A marina flat versus a berth right, what the coastal law limits and what to check before the deposit.
El Masnou is a compact coastal town in the Maresme with its own sports harbour: 24,727 residents on 3.39 km² in 2025 (Idescat) and 1,054 berths for vessels up to 24 m long at Port Masnou. Buyers here mostly buy flats, and the main checks by the sea concern the noise of the R1 line, damp, the coastal law and the separate regime of the berth.
What kind of town El Masnou is in figures
This is a dense town of flats, not a settlement of villas on a hillside. By the 2021 census, 45% of El Masnou's main residences measure 61–90 m², and only 19% are larger than 120 m². 22.1% of households rent, almost the same as the Maresme average (21.2%). All figures come from the municipal profile on Idescat.
For a buyer this means there are more similar flats here to compare prices against than in the neighbouring hill towns, where the market consists of detached houses. Anyone who wants a house with a plot and quiet should look there and not by the marina.
How the railway by the sea affects the choice of flat
The R1 line runs along the whole Maresme coast (Rodalies), and on the L'Hospitalet – Mataró section a train runs every 6 minutes at weekday peak hours and every 10 the rest of the time. The convenience of getting to Barcelona without a car is real here.
The flip side: the tracks run between the town and the beach. A first-line flat gets a view of the sea and the marina together with the sound of trains. Noise is checked on site early in the morning and in the evening, with windows closed and open, and it is worth looking at what glazing the windows facing the tracks have.
What is bought with the flat and what separately
A flat by the port gives no right to a place in the port. A berth at Port Masnou is arranged separately, under a contract with the company that runs the port by administrative authorisation.
| Element | How it is arranged | What to check |
|---|---|---|
| Flat | Escritura (notarial deed) and entry in the Registro de la Propiedad (Land Registry) | Nota simple (land-registry extract), debts and minutes of the comunidad (owners' association) |
| Parking space in the building | May be part of the flat or a separate registration | Whether the space appears in the nota simple and how it is described |
| Berth | Right of use under a contract with the port operator | Term of the right, transfer procedure, debts to the port |
| Sea view | Not a right, but the situation today | What the urban plan allows to be built in front of the building |
Under the port regulations, the operator grants the right to use a berth for the term of its own administrative authorisation or a shorter one (art. 24 and 25). Transfer of the right between private persons goes through the operator and with prior notice, and the contract may give the operator a right of first refusal. In the published text the term of the authorisation is stated as running to 2 July 2026, so the current term and the conditions for renewal should be confirmed with the port before any transaction involving a berth.
What the coastal law limits
The Ley de Costas (Spain's Coastal Law) sets a protection zone 100 m wide from the inner edge of the ribera del mar (the shore zone), where buildings for housing are prohibited (art. 23 and 25 of Ley 22/1988). For land that was already urban in 1988, the width of the zone is 20 m, and existing buildings are kept (disposición transitoria tercera, the third transitional provision).
For a flat in an existing building this rarely gets in the way of living there, but it affects rebuilding, extension and repair of the facade on the sea side. Where the deslinde line (the official boundary of the coastal public domain) runs in relation to a particular building is checked by the abogado (lawyer). The house by the sea and the coastal regime are covered in more detail in the article Ley de Costas and a villa by the sea.
How to check a flat by the marina before making an offer
The order of checks runs from what cannot be fixed by refurbishment to what can.
- Noise. Listen to the trains and the port at different times of day, including a summer weekend evening.
- Damp and facade. By the sea, metal elements rust faster and plaster deteriorates. The signs of damp are covered in the article on damp.
- Owners' association. Request the minutes of meetings for several years: repairing the facade, balconies and garage in a building by the sea costs more. How to read them is described in the article on the comunidad.
- Parking and storage room. Check in the nota simple whether they are part of the flat or registered separately.
- The berth, if it is part of the deal. Obtain from the port a certificate of the right, its term and the absence of debts, and have the transfer contract drawn up through the operator.
- Price. Compare it with closed transactions in the same neighbourhood. The seller builds the marina view into the price, and the buyer checks how much was actually paid for it.
Who El Masnou does not suit
The town does not suit someone looking for quiet and a house with a garden: it has dense development, a train by the sea and a lively seafront in summer. Nor does it suit a buyer who expects to get a berth "included" with the flat: it is a separate right with its own term and rules.
More caution is needed from anyone planning to rebuild a first-line building: the coastal law and the urban plan may limit the works. How the Maresme and the Garraf look from the standpoint of an investor and a project is analysed in the review of the coast. DNPI checks the price of a specific flat against closed transactions as part of a property valuation.
Questions and answers
How do I get from El Masnou to central Barcelona?
By the R1 train, which runs along the coast and reaches the centre without a change. On the stretch to Mataró a train runs every 6 minutes at weekday peak hours.
Is the berth included in buying a flat by the port?
No. A berth at Port Masnou is arranged by a separate contract with the port operator, as a right of use for the term of its authorisation. Transfer of the right goes through the operator.
Can a first-line flat or house be extended?
It depends on its position relative to the Ley de Costas protection zone and on the urban plan. In the protection zone new buildings for housing are prohibited, existing ones are kept, and works are checked with an abogado and an architect.
Why are flats by the marina more expensive?
Sellers build the view and the closeness to the port into the price. Whether the premium is justified is checked against closed transactions in the same neighbourhood, not against listings.
What should be checked first in a building by the sea?
Train noise, the condition of the facade and balconies, the owners' association minutes on upcoming repairs and damp in the flat. It is cheaper to check this before the arras deposit than to fix it after the purchase.
