Advice on renting

Do you want to know your rights and obligations as a tenant? Or as a property owner? You will find all the information about housing regulations here.

Rights and obligations for rented accommodation

Housing discipline is a relatively new concept that appeared with the 2007 Right to Housing Act. This Act provides a clear framework concerning the rights and obligations of the different parties that interact in the property market.

Within this framework, the concept of slum and difficult-to-access housing, for example, can be easily determined, and associated with certain fines to be paid. The framework, which did not exist 10 years ago, allows citizens to claim their rights while also establishing rights and obligations for the administration

Do you want to know about the rights and obligations associated with your rental contract?

You will find the most relevant advice concerning your rental contract here, with information about the rights and obligations of each and every party involved.

The state of the flat must be taken into consideration

Before renting a flat, it is a good idea to make a thorough inspection, to make sure that the property meets your needs.

You should consider a series of factors that directly affect the quality of people's lives. Natural light, low levels of noise pollution, thermal protection and the cleanliness of the environment are key factors for the comfort of a home.

In the case of furnished flats, you should check that the washing machine, fridge, cooker and water heater are in working order. It is important to check the water, gas and electricity installations and, in older buildings, make sure the bathroom has adequate water pressure. It is also a good idea to ask for a gas-inspection certificate.

You should consider the dwelling's surroundings

A property's surroundings and neighbourhood services and facilities can also be key factors when making your choice. Some of the variables that influence the decision are proximity to public transport, place of work, shops and markets, and the existence of schools, leisure areas, green areas, etc.

In addition to all of that, you should check if there are any projects planned or under development that may change the area, such as an urban-development project. If this is the case, the City Council can provide information on the projects to help you assess if they are beneficial or disadvantageous.

Certificate of Occupancy

It is important to check that your chosen flat has the corresponding Certificate of Occupancy. This document guarantees that the dwelling is fit to live in, and it is essential for obtaining water, gas and electricity services.

You need this document to let accommodation. It must be certified by a qualified technician, architect or quantity surveyor, and it is issued by the Generalitat of Catalonia.

Rental contract

Before signing a rental contract, you should check that the person letting the flat is really the owner, who is able to rent the flat, and that the person is who they claim to be. In cases where the person letting the flat is acting on behalf of the owner, make sure that they have sufficient power of attorney to do so.

The contract must be formalised in writing and each and every clause it contains must be analysed. If in doubt about something, ask what it means. If something remains unclear, you should not sign. To sum up, it is of prime importance to analyse all the contract's conditions before signing it, because once you have signed, it is too late.

If several people want to rent the flat, it is highly recommendable that they all sign the contract, because they will then be listed as occupants.

Rental agreements signed after 1 January 1995 are regulated by the Urban Rental Act (LAU, Act 29/1994) (CAT). The modifications introduced by Act 4/2013, concerning flexibilisation measures and fostering the rental market (ESP) should also be taken into consideration.  

Since Act 4/2013 came into force, rental agreements have been regulated, firstly, by the wishes of the parties involved, Chapter 2, and, additionally, by the Civil Code.

When formalising a rental contract, the rent and the duration of the contract are what the signing parties have agreed. However, it should be remembered that if the duration of the contract is open, the LAU establishes that where a duration of less than three years is agreed, the contract may be extended to three years, something which is optional for the tenant and obligatory for the owner. 

Basic services

Once you have chosen your dwelling (either purchased or rental), you have to get connected to the basic services of electricity, gas, water and telephone. Contracting these services is the responsibility of the tenant, in the case of rented accommodation, or the owner in the case of purchased properties.

Electricity, gas, and telephone services can be contracted with any company, given that the market has been deregulated. 


An insurance contract must always be formalised in writing. The insurance company is obliged to give the insured person a policy, a document in which the insurance company must identify itself, the insurance broker and exactly what is being insured. The types of risk covered, the objects that are being insured, the amount insured and the cost of the insurance premium must all be specified. 

Advertising, information and offer

In rental accommodation offers, the consumer must be provided with sufficient information concerning the dwelling's basic conditions, as well as the basic conditions of the contract. This information must be given before the receipt of any payment on account. The minimum information about an offer must include the following:

A description and physical conditions of the dwelling, indicating the useful surface area and the services, installations and utilities (occupancy certificate or definitive qualification for HPO social housing).

The total price of the rent, with a breakdown and details of services, and other amounts that will be assumed by the tenants, stating the periodicity of payment, the rental period, and the means of updating the price throughout the duration of the rental contract.

If a company selling a list of available rental accommodation is contracted, you must first ensure the seriousness and credibility of those professionals, in order to avoid unpleasant surprises (flats already rented, flats that the seller does not want to rent out, etc.). You should read the contract's conditions before signing it, and pay special attention to the conditions, the services offered, the price and the duration of the contract. If you are in any doubt, you can ask for a copy of the contract so that you can study it carefully before signing it.

Pay careful attention to advertisements offering rental accommodation, to make sure that they are not misleading and that the offer really corresponds to the advertisement.

If the situation is irregular, you can make an official complaint to the Generalitat of Catalonia.
