Semi-Detached in Spain 2026: Pareado vs Adosado Explained

Adosado is a terraced house: attached on both sides, in a row of eight to forty units built to one plan. An end unit is sold as adosado esquinero or final de hilera and asks roughly 8% to 15% more for its extra side wall and wider patio. Plots are small, often 90 m2 to 150 m2, with a parking bay at the front, a patio at the back and a roof solarium doing the work a garden does at home.

Pareado, listed as casa pareada or chalet pareado, is the semi-detached pair: two houses, one shared wall, mirrored floor plans. It is the nearest Spanish equivalent to a British semi, with one difference that changes the proposition. The plot is usually walled, 200 m2 to 400 m2, with room for a private pool of around 6 m by 3 m.

Chalet independiente, often just called a villa, is fully detached and touches nothing: four free walls, its own plot, its own gate. The PGOU sets a minimum parcel size for detached housing, commonly 400 m2 or 500 m2 in coastal urbanisation zones, which is why independientes are scarce inside the high-density estates of the boom years.

Dúplex is not a semi-detached house at all, and that is where British and Northern European buyers lose money on an assumption. Outside Spain the word suggests a building split into two homes. In Spain it means one dwelling on two floors inside an apartment block: internal staircase, block comunidad, communal pool, no plot. Bungalow carries the same trap here, where it usually means a ground-floor or upper-floor unit in a low terrace and is legally an apartment. We took the wider vocabulary apart in townhouse, duplex and adosado explained.

	Adosado	Pareado	Chalet independiente	Dúplex
English equivalent	Terraced house	Semi-detached house	Detached villa	Two-storey apartment
Shared walls	Two, or one at the end of a row	One	None	Floors and walls
Typical plot	90 to 150 m2	200 to 400 m2	400 to 900 m2	None
Pool	Communal	Private, small	Private	Communal
Comunidad	Almost always	Usually, often small	Only on a private estate	Always
Typical asking price	EUR 165,000 to 340,000	EUR 240,000 to 470,000	EUR 380,000 upwards	EUR 130,000 to 300,000
Rough annual running cost	EUR 1,650 to 2,850	EUR 1,550 to 3,900	EUR 3,000 to 6,300	Set by block fees

The ladder holds on almost every urbanisation: adosado cheapest, pareado in the middle, chalet independiente dearest. The dúplex undercuts all three because it carries no land.

The comunidad and the shared wall

Nearly every adosado and most pareados here sit inside a comunidad de propietarios. Where the estate is separate houses sharing roads, gates, gardens and a pool, it is constituted under article 24 of the Ley de Propiedad Horizontal as a complejo inmobiliario privado. Four consequences follow.

• Your quota is fixed by the coeficiente de participación in the escritura, not by how much you use the pool. A larger unit pays more even if it stands empty ten months a year.
• The junta can vote a derrama, an extraordinary levy, for road resurfacing, pool filtration or a new gate. Roughly EUR 400 to EUR 2,000 per house is ordinary.
• Under article 17.12 of the Ley de Propiedad Horizontal, reformed in 2025, three-fifths of owners can prohibit or condition tourist letting. Read the minutes of the last two juntas before you offer.
• Unpaid fees attach to the property for the current year plus the three previous ones. Ask for the certificado de estar al corriente de pagos, and check the reserve fund, which must be at least 10% of the annual budget.

The wall itself depends on the regime. Where the two houses are independent properties it is a medianería under articles 571 to 579 of the Código Civil, and repair or rebuilding falls on both owners in proportion to their right in it. Inside a horizontal property regime, article 396 of the Código Civil and article 10 of the Ley de Propiedad Horizontal make the structure and party walls common elements, so the comunidad orders the work and bills every owner.

Sound carries. DB-HR, the acoustic section of the Código Técnico de la Edificación, only became mandatory in 2009, and many Costa Blanca adosados went up between 1999 and 2007 with a single leaf of brick between dwellings. Visit at nine on a Saturday evening in August, not eleven on a Tuesday in February. Check the nota simple against the Catastro plan too, since undeclared pools and glazed-in terraces are common on attached houses.

What it costs to run, and who buys which

The adosado pays the biggest communal quota but the smallest IBI and insurance bill. The independiente pays no quota and carries every euro of pool, garden and insurance itself, so a pareado without a private pool can cost less to hold than an adosado. Those figures exclude mortgage payments, and non-resident owners add Modelo 210 on top. Fuller breakdown in villa versus apartment: the real annual cost.

The adosado suits a buyer who wants a house-shaped holiday base at apartment money, is happy with a communal pool and values locking up and leaving for eight months. The cost is neighbours on both sides and a resale market where nine near-identical units may be listed at once, so your exit price is set by the most impatient owner on the estate.

The pareado is the pragmatic middle: one neighbour instead of two, a real plot, usually a private pool, far fewer comparable units when you sell. Our north Costa Blanca stock reaches into this band, for instance WES-1930D Polop house, 3-bed 144 m2, EUR 470,000. Confirm the type on the nota simple before you fall for the photographs, because a pareado and an independiente carry different plots, pools and monthly fees.

The independiente needs a real budget and a tolerance for maintenance. Near the top of our present house range, WES-1411 3-bed house in Benidorm buys privacy and a pool nobody else swims in, and it will take longer to sell than anything attached. The attached-house belt on the southern Costa Blanca and Costa Cálida runs through Orihuela Costa, Ciudad Quesada, Torrevieja and Los Alcázares. Start with Orihuela Costa sale listings.

Frequently asked questions

Is a pareado the same as a British semi-detached house?

Structurally yes: one shared wall and a mirrored plan. The difference is the plot. A Spanish pareado usually sits on a walled parcel of 200 m2 to 400 m2 with a private pool and off-street parking, and it usually sits inside a comunidad de propietarios that charges a monthly quota and can vote on how you use it.

Does dúplex mean a semi-detached house in Spain?

No. In Spain a dúplex is a single apartment arranged over two floors inside a block, reached from a communal stairwell or lift: no plot, a communal pool, full apartment-block rules. The word for a semi-detached house is pareado. The terraced version, attached on both sides, is an adosado.

Who pays when the shared wall or the roof between two houses leaks?

Where the two houses are independent properties, the wall is a medianería, and articles 571 to 579 of the Código Civil split repair and rebuilding between both owners in proportion to their right in it. Inside a horizontal property regime the comunidad carries structural repairs and recovers the cost through a derrama.

Can the community stop me renting my adosado to tourists?

It can. Under article 17.12 of the Ley de Propiedad Horizontal, reformed in 2025, three-fifths of owners can prohibit or condition tourist letting. Read the minutes of recent juntas and the current statutes before you buy, and get the position in writing.
