On the Costa del Sol, with long, hot summers, air conditioning is one of the first questions that comes up when renting a home. Is the landlord required to install it? The short answer is that, as a rule, no; but there are important exceptions worth knowing, whether you are a landlord or a tenant.
As a rule, there is no obligation
Summer heat is treated as a matter of comfort, not habitability. Spain's Urban Tenancy Law (LAU) requires the landlord to keep the home in a condition fit to be lived in, but not to provide comfort upgrades. So the mere absence of air conditioning does not breach the landlord's obligations.
The exception: if A/C is in the contract
If the rental contract states that the home has air conditioning, the situation changes: the landlord must install it or repair it if it stops working. The reasoning is logical: the tenant chose to rent counting on that feature. In that case it is a necessary repair, not an improvement, and it falls to the landlord.
Improvement or repair: why the difference matters
The distinction is key because it determines who pays and whether the rent can rise:
- Repair: maintaining something that already exists (including A/C agreed in the contract). The landlord covers it, with no rent increase.
- Improvement: installing new A/C in a home that never had it. It can justify a rent increase, but with limits.
When it counts as an improvement, the LAU allows the increase to be passed on only after five years from the signing of the contract and capped at 20% of the current rent. Before that period, only with the tenant's express agreement.
What about cases of extreme heat?
Air conditioning is not an ordinary habitability requirement. However, in extreme situations - very high temperatures combined with serious structural defects, such as very poor insulation or hazardous materials - a home could be deemed uninhabitable on health-risk grounds. These are exceptional cases and must be assessed individually.
What to keep in mind on the Costa del Sol
In a climate like ours, air conditioning adds real value: it improves comfort and makes a home more appealing to rent or sell. For landlords it is a worthwhile investment in returns; for tenants, it is best to state clearly in the contract which equipment the home includes and who covers its upkeep. And remember: a tenant may only install A/C on their own with the landlord's consent and the building community's authorisation.
Conclusion
In short, the landlord is not required to provide air conditioning unless the contract includes it or exceptional habitability circumstances arise.
