Buying a Townhouse (Adosado) in Spain: What to Check

An adosado looks like a small standalone house, but legally it behaves more like an apartment with a garden — shared walls, a community of owners, and boundary questions a detached villa never raises.

The party wall changes things

Unlike a fully detached villa, an adosado shares at least one party wall (medianeria) with a neighbouring unit. Structural changes affecting that wall generally require at least formal notice to the neighbouring owner, and often their agreement, before you can proceed.

Almost always a community of owners

Adosados are typically part of an urbanizacion with shared amenities — pools, gardens, private roads — which brings a community of owners, monthly fees and a shared reserve fund into the picture, much like an apartment building but spread across a housing estate.

Boundaries and access are the specific risk here

Confirm the exact boundary lines with neighbouring units, and check that any shared driveway or access route is a properly registered easement — not an informal arrangement between the current owners that could be disputed once ownership changes.

What to check with the community before buying

Review the community statutes, the fee schedule, the reserve fund balance, and recent meeting minutes for any planned major works or ongoing disputes. This is typically where hidden future costs on an adosado surface first — long before they show up in the sale listing.

Frequently Asked Questions

Is an adosado legally different from a detached villa?

Yes, in one key respect — an adosado shares at least one party wall (medianeria) with a neighbouring unit, which means certain structural changes may require the neighbour’s consent or at least formal notice, unlike a fully detached villa.

Will I automatically be part of a community of owners?

Almost always — adosados are typically part of an urbanizacion with shared amenities like pools, gardens or private roads, which means a community of owners, monthly fees, and a shared reserve fund, similar to an apartment building but for a housing estate.

What boundary issues are specific to a townhouse?

Shared boundaries and access are the main risk — confirm the exact boundary lines with neighbouring units and check that any shared driveway or access route is a properly registered easement, not an informal arrangement that could be disputed later.

Can I make structural changes to a party wall without asking anyone?

Generally not freely — because the wall is shared, structural changes affecting it typically require at least formal notice to, and often the agreement of, the neighbouring owner, which is different from a standalone house.

What should I check with the community before buying?

The community statutes, the fee schedule, the reserve fund balance, and recent meeting minutes for any planned major works or disputes — this is where hidden future costs on an adosado usually surface first.
