Repairs & upkeep (who pays what) 3 min read · published September 11, 2025
As a tenant in Spain, understanding who must pay a rent increase after improvements to the home is essential to protect your rights. Works can be minor maintenance or improvements that increase value; according to the Urban Leases Act and the contract, the cost may fall to the landlord, or part may be passed to the tenant if agreed. This article clearly explains what distinguishes renovation from repair, what procedures to follow before paying, how to document the works and when to claim against the landlord or the courts. You will find practical steps, deadlines and official resources for tenants in Spain, written in accessible language for non-experts.

Who pays for improvements?

In general, repairs necessary to maintain habitability are usually the landlord's responsibility, while improvements that raise the property's value can lead to discussion about who assumes the cost. The Urban Leases Act should be the first reference to interpret contractual obligations.[1]

Basic habitability is usually the landlord's responsibility.

Repair vs improvement

  • Repair: fixes necessary for habitability (heating, plumbing, leaks) and generally paid by the landlord.
  • Improvement: works that increase value or comfort; their cost can be negotiated and do not automatically justify a rent increase.
  • Minor maintenance: small conservation interventions that usually correspond to the landlord under the contract.
Always document works with photos and invoices.

Can the landlord raise the rent for improvements?

The landlord can only pass costs on to the tenant if there is a contractual agreement allowing it or if the increase is authorized under applicable law. In the absence of an agreement, a unilateral increase can be challenged in court. Claims related to leases are usually processed in the Court of First Instance.[2]

Do not pay an increase without requesting written justification.

What to do before paying

  • Keep invoices, estimates and photos of the works as proof of scope and cost.
  • Send a written notification requesting the cost breakdown and technical justification.
  • Do not agree to payment until you receive documentation and a signed agreement on who bears the cost.
  • If there is no agreement, seek advice and consider judicial action in the Court of First Instance.
Respond within legal deadlines to avoid losing rights.

Frequently Asked Questions

Which works can justify a rent increase?
Works that significantly increase the property's value or use can justify negotiation, but do not automatically trigger an increase if not agreed in the contract.[1]
If the landlord demands payment, what can I request?
You can request invoices, a cost breakdown, technical reports and timelines; without documentation, payment is not advisable.
Where do I file a claim if there is no agreement?
If the dispute cannot be resolved amicably, you can file a claim at the competent Court of First Instance or seek advice from municipal housing offices and free legal services.[2]

  2. Document the works with photographs, estimates and invoices.
