Almost every right you have as a renter in Spain comes from one law: the Ley de Arrendamientos Urbanos. Here it is decoded into plain English — what it covers, the protection it gives, and how the 2019 and 2023 reforms changed the picture.
The Ley de Arrendamientos Urbanos — usually shortened to the LAU — is the Spanish statute that governs the renting of urban property. It was passed in 1994 (as Law 29/1994) and has been amended several times since, most significantly in 2019 and again by the 2023 Housing Law. If you rent a flat or house in a town or city in Spain, the LAU is the framework that decides how long you can stay, how much deposit you can be asked for, how and when the rent can change, who is responsible for repairs, and how a tenancy can lawfully be brought to an end.
For a foreign tenant, the single most useful thing to understand is this: the LAU sets a floor of rights that a contract cannot take away. Many of its protections are mandatory — they apply to a residential tenancy whether or not the contract mentions them, and a clause that tries to reduce them below the legal minimum is simply not enforceable. That is why a Spanish lease can look one-sided on paper and yet give you far more protection than it appears to. The catch is the reverse, too: those strong protections attach mainly to a long-term home, and contracts are sometimes structured to fall outside that category. Knowing where the line sits is the whole game.
Which category your contract falls into decides almost everything else.
A lease whose primary purpose is to meet the tenant's permanent need for housing — your main home. This is the category the LAU protects most strongly: security of tenure of up to five or seven years, a capped deposit, controlled rent, and protection from arbitrary eviction. If Spain is where you live, this is the lease you should have.
Everything else — including seasonal or temporary lets (arrendamiento de temporada), commercial premises, and second-residence arrangements. These are governed far more by what the parties agree and far less by mandatory protection. A "seasonal" home is the most common trap: it sits in this weaker category by design.
This is the LAU's flagship protection, and the one foreign tenants most often lose without realising. For a lease of a dwelling, the law gives the tenant the right to remain for a minimum protected period through what is called the prórroga obligatoria — the compulsory extension. Even if your written contract says one year, it renews automatically, year by year, up to the protected minimum, as long as you meet your obligations. Since the 2019 reform, that minimum is five years where the landlord is an individual, and seven years where the landlord is a company or other legal entity.
At the end of that protected term, the law adds a further cushion: if neither party gives notice in time, the contract enters the prórroga tácita — a tacit extension, currently of up to three further years, one year at a time. To stop the automatic renewal at the end of the mandatory term, the landlord generally has to give you several months' written notice (four months under the current rules); a tenant who wants to leave at that point gives shorter notice (two months). The practical effect is that a residential tenant in Spain enjoys a level of stability that surprises many people from countries where year-to-year renting is the norm.
The way this is most often defeated is by pushing the contract into category B above. A genuine seasonal contract does not carry the prórroga obligatoria, so a landlord who labels a permanent home as "seasonal" is, in effect, contracting you out of years of security. That is exactly why the first question in any contract review is which category the lease really belongs to.
The LAU sets the deposit precisely. For a lease of a dwelling the fianza is one month's rent; for a lease for use other than a dwelling it is two months. The landlord is legally required to lodge the fianza with the housing body of the relevant autonomous community — it is not meant to sit in the landlord's pocket. At the end of the tenancy it must be returned, and any delay beyond a reasonable period can attract interest in the tenant's favour.
The law also allows the parties to agree an additional guarantee (garantía adicional) on top of the fianza — for example, extra cash or a bank guarantee. For a residential lease within the mandatory term, this additional guarantee is capped at the equivalent of two months' rent. So the most a landlord can normally require at the start of a standard residential tenancy is one month's fianza plus up to two months' additional guarantee. Demands well beyond that fall outside the usual framework and are worth questioning before you pay. If a deposit is later withheld without proper justification, the LAU is firmly on the tenant's side — see deposit disputes.
Under the LAU the rent is freely agreed at the outset, but once set it can only change as the law and the contract allow. The rent can be reviewed (usually annually) only if the contract provides for it, and the increase is tied to an official reference index rather than left to the landlord's discretion. Historically that index was the Consumer Price Index (IPC); more recent reforms have moved toward a dedicated rental reference index and introduced temporary caps on annual increases. Because the precise figures have changed from year to year, the safe rule for a tenant is simple: an increase must follow the contract and the prevailing legal index, and a clause that lets the landlord raise the rent "at will" or "by any amount" is not valid.
The 2023 Housing Law added a further layer in areas formally designated as zonas tensionadas — stressed markets where rents are high relative to incomes. In those areas additional limits apply to how much rent can be set and increased, including specific constraints on large landlords. Whether a particular town or district is designated is a regional decision, so it varies across Spain and over time. We check the current position for your specific location as part of any advice.
The LAU does not give a residential tenant a free hand to sublet. A partial sublet — letting out a room while you remain — is generally only permitted with the landlord's written consent, and the sublet rent cannot exceed the rent you pay. Assigning the contract entirely to someone else likewise needs the landlord's agreement unless the law provides otherwise. Informal arrangements — quietly taking in a paying flatmate, or handing your room to a friend when you leave — can breach the contract and, in the worst case, give the landlord grounds to end the tenancy. If you are sharing or planning to move someone in, it is worth getting the position checked first.
The law does, however, protect certain people connected to the tenant. In defined circumstances a spouse or partner who has been living in the home, or family members, may be able to continue the tenancy if the named tenant leaves or dies during the term. These subrogation rights are technical and depend on the facts, but they exist precisely to stop a household being put out simply because the person who signed is no longer there.
Two recent waves of change reshaped the balance between landlord and tenant.
Royal Decree-Law 7/2019 strengthened tenant protection: it lengthened the mandatory term to five years for private landlords and seven for company landlords, extended the tacit-renewal period, capped the additional guarantee at two months, and increased the notice landlords must give. For most residential tenants today, the 2019 settlement is the baseline.
Law 12/2023 (the "right to housing" law) introduced stressed-area rent controls (zonas tensionadas), placed the cost of letting-agency fees on the landlord rather than the tenant, defined "large holders" (grandes tenedores) with extra obligations, and brought in temporary caps on annual rent increases. How much of it applies depends on the region and on official designations.
Two practical takeaways for tenants flow from these reforms. First, you should not be charged the agency's fee on a residential let — that cost now sits with the landlord. If you are asked to pay a month's rent "for the agency" to secure a long-term home, question it. Second, rent increases are more tightly controlled than many landlords admit, especially in designated areas. Because the detail shifts as regulations are updated, the value of advice is in pinning down the rule that applies to your contract, in your region, right now.
The LAU treats the two sides very differently when it comes to ending a tenancy, and the asymmetry is deliberately protective of the tenant. You, as the tenant, may withdraw from a residential lease once you have been in the property for at least six months, giving the landlord at least 30 days' written notice. The contract can provide for limited, proportionate compensation if that was agreed in writing — typically linked to the unexpired term — but it cannot impose a penalty that makes you forfeit far more than the law allows.
The landlord, by contrast, cannot simply end a residential tenancy within the protected term. They need a lawful ground. The most common is a genuine need to recover the property as a home for themselves or a close family member, and even that is only available where it was reserved in the contract and proper notice is given, and generally not in the very first year. Otherwise the landlord must wait until the end of the mandatory term and give the required notice, or rely on a serious breach by the tenant — most often non-payment of rent — pursued through the courts. A landlord can never lawfully evict by changing the locks, removing belongings or cutting off utilities; eviction in Spain is a court process. If you are facing one, read our guide to eviction defence and act quickly.
Understanding what the LAU does not protect is as important as knowing what it does, because the gaps are exactly where foreign tenants get caught. Several common arrangements sit wholly or partly outside the residential regime described above:
The recurring theme is that the protection follows the nature of the arrangement, not its label. A landlord cannot escape the residential regime simply by writing "tourist" or "seasonal" at the top of a contract for what is genuinely your home — but they will often try, and untangling that requires looking at the substance. That is precisely the judgment a contract review provides.
A statute is only as useful as your ability to invoke it at the right moment. In practice, the LAU does its most valuable work at three points in a tenancy. The first is before you sign, when the contract can still be shaped — this is when establishing the correct category, the term, the deposit and the cost-sharing actually changes your position, rather than just describing it. The second is during the tenancy, when questions arise over repairs, a proposed rent increase, or a landlord's behaviour, and knowing the legal default lets you push back with confidence. The third is at the end, over the deposit or a notice to leave, when the asymmetry the law builds in — strong tenant protection, narrow landlord grounds — comes into its own.
At each of those points the same principle applies: the LAU gives you the rights, but you have to assert them, and a landlord is far more likely to respect them once they see that you understand the law and have advice behind you. For a foreign tenant, that combination — the statute plus someone who can apply it in your language and act on it in Spanish — is what converts a paper right into a real one. Whether you need a lease checked, a deposit recovered, or an eviction defended, the starting point is always the same: what does the LAU actually say about your situation, and how do we use it.
LAU stands for the Ley de Arrendamientos Urbanos — the Law of Urban Leases. It is the Spanish statute (Law 29/1994) that governs the renting of homes and premises in towns and cities, and it has been reformed several times, most notably in 2019 and 2023.
If you are renting an urban property — a flat or house in a town or city — then yes, the LAU applies. It distinguishes between leases of a dwelling (your main home, strongly protected) and leases for other uses such as seasonal or commercial lets (less protected). Agricultural land and tourist lets fall under separate rules.
For a primary residence, the compulsory extension (prórroga obligatoria) lets you stay up to five years if the landlord is an individual, or seven years if the landlord is a company — even if the written contract is shorter. After that, a tacit extension of up to three further years can apply if neither party gives notice in time.
Under the LAU the fianza is one month's rent for a dwelling (two months for other uses), and it must be lodged with the regional housing authority. A landlord may agree an additional guarantee on top, but for a residential lease within the protected term this is capped at two months' rent.
Many of the LAU's residential protections are mandatory, meaning a clause that tries to reduce them below the legal minimum is not enforceable. That is why a residential tenant often has more protection than a one-sided contract suggests. The main way rights are lost is not by clause but by category — a home wrongly let as a "seasonal" property falls outside the strongest protections.
Royal Decree-Law 7/2019 strengthened tenant protection — extending the mandatory term to five years (seven for company landlords), lengthening the tacit-renewal period, capping the additional guarantee at two months, and increasing the notice landlords must give. It is the baseline for most residential tenancies signed since.
Law 12/2023 introduced rent controls in officially designated stressed areas (zonas tensionadas), shifted letting-agency fees onto the landlord, defined "large holders" with extra obligations, and brought in temporary caps on annual rent increases. How much applies depends on the region and on official designations, which change over time.
Under the 2023 reform, the cost of letting-agency services on a residential lease falls on the landlord, not the tenant. If you are asked to pay a substantial agency fee to secure a long-term home, that is worth questioning.
Only with limits. A partial sublet — renting out a room while you remain — generally needs the landlord's written consent, and the sublet rent cannot exceed your own. Subletting or assigning without consent can breach the contract, so check the position before taking in a paying flatmate.
Yes. The LAU does not distinguish by nationality or immigration status. A foreign tenant has exactly the same rights as a Spanish tenant on an equivalent lease. The difference is awareness, not entitlement — which is why independent advice is valuable.
It depends on the arrangement. Renting a room in a property where the landlord also lives is often treated as outside the standard residential lease, with your protection depending heavily on the written terms. Renting a room within a tenancy you hold (a sublet) is subject to the LAU's sublet rules and usually needs the landlord's written consent. Because room rentals sit in a greyer area, they are worth having checked before money changes hands.
As a general rule the IBI property tax, community fees and building insurance are the landlord's responsibility. The LAU does allow some costs to be passed to the tenant where this is clearly and lawfully agreed in the contract, but blanket clauses dumping all of the landlord's ownership costs onto the tenant are often unenforceable. We check exactly what your contract says against what the law permits.
We advise English-speaking tenants across Spain on how the LAU applies to their specific contract and circumstances — from reviewing a lease before signing to recovering a deposit or defending an eviction. Because the rules vary by region and have changed with recent reforms, advice on your exact situation is worth more than a general summary.
