Living in Castelldefels, Barcelona (2026)

Castelldefels in numbers

What is it like to live in Castelldefels?

Castelldefels has five kilometres of wide beach, pine woods and streets of houses with gardens. It has moved from holiday homes to year-round living: families, airport and aviation workers, remote workers and a mixed international crowd, with the British School on the doorstep.

Who is Castelldefels for?

How much is rent in Castelldefels in 2026?

A one-bedroom flat in Castelldefels is advertised at about 910 to 1,120 EUR a month, and a three-bedroom at about 1,520 to 1,860 EUR. That is 16.9 EUR per square metre (idealista price report, June 2026) on a 60 m² and a 100 m² flat, plus or minus 10%.

The official figure is lower: the average rent on contracts actually signed in Castelldefels (281 contracts) was 1,142 EUR a month (Incasòl rental deposits (Generalitat de Catalunya), Q1 2026), the 11th highest of the 18 places we compare. It is lower than the asking price because it covers every new contract, including small flats, and because the rent cap holds many renewals down. Arriving now, budget against the asking price.

A room in a shared flat costs about 600 EUR a month across Barcelona (idealista room-rental report, Q2 2026).

Is rent capped in Castelldefels?

Yes. Castelldefels is a declared stressed housing market ("zona tensionada") since March 2024, so the rent on a new contract is capped under the state housing law, Ley 12/2023. In general a new rent cannot be higher than the previous tenant's rent, updated by the official index. Large landlords, and flats that have not been rented in the last five years, are capped at the official reference price index instead. The contract must state the previous rent, so ask to see it. Since January 2026 the same limits also cover seasonal and room rentals under the Catalan law 11/2025, which is under appeal at the Constitutional Court but in force.

How much does it cost to buy in Castelldefels?

Homes in Castelldefels are advertised at about 4,423 EUR per square metre (Fotocasa price index, September 2026), the 16th most expensive of the 18 places we compare. On the same benchmark sizes:

• One bedroom, 60 m²: 239,000 to 292,000 EUR
• Three bedrooms, 100 m²: 398,000 to 487,000 EUR

That figure covers the whole municipality. Can Bou, by the beach, is 7,045 EUR/m2 and Vista Alegre 2,589.

What do you pay on top of the price when buying in Castelldefels?

Buying a resale home in Catalonia carries a transfer tax, ITP, of 10% up to 600,000 EUR, 11% from 600,000 to 900,000, 12% to 1.5 million and 13% above, each rate applied only to its own slice of the price, under Decret llei 5/2025, in force since 27 June 2025 (Agència Tributària de Catalunya, October 2026). A reduced 5% rate exists for buyers aged 35 or under, large families, single parents and buyers with a disability, but only for a main home and with a household income below about 36,000 EUR, so most buyers on these pages pay the full rate. A new build pays no ITP: it pays IVA at 10% plus AJD at 1.5%. On top come notary, land registry, gestoría and a lawyer.

On a 443,000 EUR three-bedroom flat in Castelldefels, the middle of the band above:

• ITP: about 44,000 EUR
• Notary, registry, gestoría and a lawyer: roughly 2,350 to 6,300 EUR
• Buying outright: about 489,000 EUR in total
• With a non-resident mortgage at 70%: about 180,000 EUR of your own money

So the costs on top come to roughly 10.5% to 11.4% of the price. Non-resident lenders generally lend 60–70% of value.

The tax is self-assessed on form 600 with the Agència Tributària de Catalunya within one month of the deed. Many websites quote 30 working days, which is the national default, not the Catalan rule.
