What is the rent reference index?

The rent reference index is an informational tool that some administrations use to guide limits on increases and practices in pressured areas; its application depends on regional and state regulations and the lease clause [1].

In most regions, the index guides rent increase policies.

How it affects initial rent and increases

The initial rent agreed by the parties is free unless a specific rule limits it in certain areas. The reference index can be used to assess whether a subsequent increase is abusive or outside criteria, but it does not replace the written lease. If the landlord proposes an increase, review the update clause and request receipts.

  • Review the contract and the rent update clause (rent).
  • Check whether the dwelling is declared a pressured area by the autonomous community.
  • Request receipts and proof from the landlord to compare the increase with the index (evidence).
  • Respond in writing within the indicated deadlines if you receive a requirement or proposed increase (within).
  • Consider legal advice, mediation or consultation at local consumer and housing services (contact).
Respond to judicial or administrative notifications within the indicated deadlines.

What documentation should you keep

Keep the lease, all payment receipts, written communications with the landlord, photos of the dwelling and any technical habitability reports. This documentation is crucial if you need to claim before consumer offices or court.

A folder with clear dates and evidence makes processes before authorities and courts easier.
