Sign with Confidence: The Spanish Rental Contract Checklist
Key clauses, red flags, and what to check before you sign.
The contract you sign matters more than you think
Spanish rental law is one of the most tenant-friendly frameworks in Europe, but those protections only kick in if your contract qualifies. The Ley de Arrendamientos Urbanos (LAU) guarantees a minimum five-year lease, caps your deposit, limits rent increases, and makes a long list of abusive clauses unenforceable.[1] The catch is that all of this depends on your contract being a standard residential lease (contrato de arrendamiento de vivienda habitual). If your landlord hands you a seasonal contract, a room-rental agreement, or something vaguely worded, you could lose most of those protections without realising it.
The landscape has shifted significantly since the Ley de Vivienda (Law 12/2023) came into force in May 2023. Agency fees are now the landlord's responsibility. Rent increases are capped by a purpose-built index rather than general inflation. Eviction procedures for vulnerable tenants have been strengthened, and tenants in stressed housing markets can request extraordinary lease extensions.[2] On top of that, Real Decreto 1312/2024 introduced a national register for rental contracts, adding a new layer of transparency to the system.[3] But none of these protections help if your contract sidesteps them from the start.
This guide walks you through every section of a Spanish rental contract, explains what the law actually says, and tells you exactly what to check before you put your name on it.
What to do:
Before signing anything, confirm the contract is titled "contrato de arrendamiento de vivienda habitual" (standard residential lease under the LAU). If it says "contrato de temporada" or "seasonal," ask why. That label strips most of your protections.
Request a full copy of the contract at least 48 hours before the signing date so you can review it without pressure.

Seasonal contracts: the biggest trap in Spanish renting
The single most important thing to check is the contract type. A standard residential lease (vivienda habitual) gives you the full protection of the LAU: minimum five-year duration, deposit caps, renewal rights, and limits on rent increases. A seasonal contract (contrato de temporada) gives you almost none of that.
Seasonal contracts exist for a legitimate reason. They cover genuine temporary stays: a university semester, a three-month work assignment, medical treatment in another city. The key distinction is not the duration but the purpose. A six-month contract can be a legitimate seasonal lease if you genuinely have a temporary reason for being there. But a twelve-month contract labelled "seasonal" when you are actually moving into your primary residence is not legitimate, regardless of what the landlord writes on the paper.[1]
This matters because Spanish courts look at the substance of the arrangement, not just the label. If you move into a property as your habitual home and the landlord has classified it as a seasonal rental, a court can reclassify the contract as a standard residential lease, restoring your full rights under the LAU. Several rulings from the Tribunal Supremo have confirmed this principle. The burden of proof falls on the landlord to demonstrate that the tenancy is genuinely temporary.[1]
The practical risk is that most tenants never challenge the classification. They accept reduced protections, pay higher deposits, and leave when the landlord says so, never realising they had the right to stay for five years. If a landlord is offering you a seasonal contract for what will clearly be your primary home, that is a red flag.
What to do:
Check the contract title and the clause describing the purpose of the lease. If it says "temporada" but you are renting the property as your habitual residence, raise this with the landlord before signing.
If the landlord insists on a seasonal contract without a genuine temporary reason, consider walking away. You would be signing away your right to a five-year minimum, deposit caps, and rent increase limits.
If you have already signed a seasonal contract that you believe should be a residential lease, you can challenge the classification. Keep evidence that the property is your primary residence: utility registrations, your empadronamiento (municipal registration), and any correspondence showing the arrangement is long-term.
Duration and renewal: your right to stay
One of the most misunderstood parts of Spanish rental law is how long your lease actually lasts. Contracts are commonly written for one year, which makes tenants think they need to renegotiate every twelve months. That is not how it works.
Under Articles 9 and 10 of the LAU, a standard residential lease automatically renews each year until it reaches a minimum of five years (seven if your landlord is a company).[1] Even if your contract says "one year," the law overrides that. You have the right to stay for the full five or seven years as long as you keep paying rent and meet your obligations. The landlord cannot refuse renewal during this period unless they need the property for personal use and meet specific legal conditions laid out in Article 9.3 of the LAU.
After the initial five or seven years, the contract enters a tacit renewal phase. If neither party gives notice at least four months (landlord) or two months (tenant) before expiry, it extends automatically in three-year blocks.[1] This means your landlord cannot simply let the contract lapse and ask you to leave. They must actively notify you, in writing, within the correct timeframe.
The Ley de Vivienda added another layer: in areas declared as "zonas tensionadas" (stressed housing markets), tenants whose contracts expire can request an extraordinary extension of up to three years under the same conditions.[2] As of mid-2025, Catalonia has been the most active region in declaring stressed zones, but other autonomous communities are following. To check whether your area qualifies, consult the official list published by the Ministerio de Vivienda y Agenda Urbana.[4]
What to do:
Check the contract duration. If it says less than one year, or if it is labelled as seasonal without a genuine seasonal reason, it may be an attempt to avoid the five-year minimum.
Note whether your landlord is a natural person (five-year minimum) or a company (seven-year minimum). This should be clear from the contract header.
Mark the renewal notice deadlines in your calendar: four months before expiry for the landlord, two months for you.
If your landlord claims they need the property back for personal use during the initial period, ask them to cite the specific LAU article. They must give you at least two months' notice and actually move in within three months, or you can reclaim the property.
Deposits: what is legal and what is not
The deposit (fianza) is one of the most common sources of conflict at the end of a tenancy, and the problems usually start at signing. Article 36 of the LAU is clear: for a residential lease, the legal deposit is exactly one month's rent.[1] Not two, not three. One.
On top of the legal deposit, your landlord can ask for additional guarantees (a bank guarantee, an extra cash deposit, or a personal guarantor) of up to two months' rent during the first five years of the lease.[1] That means the absolute maximum you should hand over at signing is three months' rent in total. If someone asks for more, they are breaking the law. After the first five years, the landlord can request additional guarantees beyond this limit, but during that initial protected period the cap is firm.
The deposit must be registered with your autonomous community's housing authority. In Catalonia, that is INCASOL (Institut Catala del Sol). In Madrid, it is the IVIMA (Instituto de la Vivienda de Madrid). In Andalusia, AVRA (Agencia de Vivienda y Rehabilitacion de Andalucia). This registration is not optional. It creates an official record of the amount paid, which protects you in any future dispute. If your landlord fails to register the deposit, they face financial penalties, and you have stronger ground if you need to challenge deductions later.[1]
When you leave, the landlord has exactly one month to return your deposit, minus any justified deductions.[1] "Justified" means actual damage beyond normal wear and tear, backed by invoices. Faded paint, scuffed floors, and minor marks from daily life are not deductible. If the landlord misses the one-month deadline, interest accrues automatically from that date. For a thorough guide on protecting your deposit from day one, see our deposit protection guide.
What to do:
Never pay more than one month's rent as the legal deposit. If the landlord asks for additional guarantees, confirm the total does not exceed three months' rent.
Ask for proof that the deposit has been registered with the regional housing authority. You are entitled to this confirmation.
Document the property's condition thoroughly at move-in: photographs of every room, close-ups of any existing damage, and a signed inventory listing appliances and furniture.
Keep all payment receipts. If you paid the deposit by bank transfer, save the confirmation. If you paid in cash, insist on a signed receipt specifying the amount and the concept.
Red flag clauses: what to reject
Not everything in a rental contract is enforceable. Spanish law is clear that any clause which contradicts the tenant protections in the LAU is automatically void, even if you signed it.[1] The problem is that most tenants do not know which clauses are void, so they comply with terms they could legally ignore. Knowing which clauses are unenforceable gives you real negotiating power before you sign.
Here are the most common illegal clauses found in Spanish rental contracts:
Waiving your renewal rights. A clause stating the contract is strictly for one year with no renewal contradicts Articles 9 and 10 of the LAU. You cannot sign away your right to the five-year minimum, even voluntarily.[1]
Requiring you to leave if the property is sold. A sale does not terminate your lease. The new owner inherits the contract and all its obligations under Article 14 of the LAU. Any clause suggesting otherwise is unenforceable.[1]
Charging you the agency fee. Since the Ley de Vivienda came into force in May 2023, estate agent fees for residential leases are the landlord's responsibility.[2] If your contract includes a clause making you pay the agent, it is void. For more on how this works in practice, see our guide to the agency gap in Spain.
Demanding more than one month's deposit. The fianza is one month. Any clause requiring two or three months as the legal deposit (not as additional guarantees, which have their own limit) contradicts Article 36.
Making you responsible for all repairs. Under Article 21 of the LAU, the landlord is responsible for maintaining the property in habitable condition.[1] A blanket clause shifting all repair costs to the tenant is void. You are only responsible for small repairs caused by ordinary wear and tear. For more on this, see our guide to small repairs and our full repairs and maintenance overview.
Allowing the landlord to enter without notice. Your right to privacy in your home is protected by Article 18 of the Spanish Constitution.[5] No contract clause can override a constitutional right.
What to do:
Read the full contract before signing. If you spot any of the clauses listed above, raise them with the landlord and ask for them to be removed or amended.
If the landlord refuses to remove an illegal clause, know that it is unenforceable regardless. But having it in writing that you objected gives you stronger footing if things go wrong later.
If you are unsure whether a clause is legal, Rent AI can review your contract and highlight clauses that conflict with the LAU or the Ley de Vivienda.
Keep a copy of the original contract and any amendments. If clauses are crossed out or modified by hand, make sure both parties initial the changes.
Rent increases: what your landlord can and cannot do
Your landlord cannot raise the rent by whatever amount they feel like. Since January 2025, annual rent increases for standard residential leases are governed by the IRAV (Indice de Referencia para la Actualizacion de Arrendamientos de Vivienda), a purpose-built index published monthly by Spain's national statistics office, the INE.[6]
The IRAV replaced the old system of tying rent increases to the CPI (consumer price index), which caused rents to spike during periods of high inflation. The new index is designed to be more stable: it takes the lowest value among headline CPI, core inflation, and a smoothed long-term rate.[6] As of March 2026, the latest published IRAV stands at 2.16%, well below the general CPI. During the 2022 energy crisis, CPI-linked increases had reached double digits, so the switch to the IRAV represents a meaningful cap on how fast your rent can rise.
This index applies to contracts signed after 25 May 2023 under the Ley de Vivienda. If your contract was signed before that date, the CPI still applies unless both parties agree to switch.[6] Either way, your landlord must give you proper notice before applying any increase, and the increase can only happen on the contract's anniversary date, not at any arbitrary point during the year. You can verify the current IRAV value using the official calculator provided by the Ministerio de Vivienda y Agenda Urbana.[4]
In stressed housing market zones (zonas tensionadas), additional restrictions apply. Large landlords (those classified as "grandes tenedores," owning ten or more urban properties, or five or more in a stressed zone) face even stricter caps on what they can charge new tenants.[2]
What to do:
Check your contract's rent review clause. It should reference either the IRAV (for contracts from May 2023 onwards) or the CPI (for older contracts). If it references a different index, or says the landlord can raise rent "at their discretion," that clause is void.
Verify any proposed increase against the official IRAV figure published by the INE. Your landlord cannot apply a higher rate.
Note when your contract anniversary falls. The increase can only take effect on that date, not before.
If your landlord proposes a rent increase that exceeds the legal cap, respond in writing citing the applicable index and its current value. Keep a copy of your response.
The inventory: your best protection at checkout
A signed inventory is not legally required in Spain, but not having one puts you at a serious disadvantage. Without a written record of the property's condition at move-in, any dispute about damage at checkout becomes your word against the landlord's. Courts tend to favour the party with better documentation, and that should be you.
A proper inventory lists every item in the property (furniture, appliances, fixtures), notes their condition, and is signed by both parties. Pair it with dated photographs and you have solid evidence if the landlord tries to make unfair deductions from your deposit. This is not just about protecting your money. A good inventory also clarifies which appliances came with the property (and therefore whose responsibility they are to maintain or replace) and establishes a baseline for normal wear and tear.
The inventory is also your first line of defence if something breaks during the tenancy. If the washing machine was already old and faulty when you moved in, and you documented that, the landlord cannot hold you responsible when it finally gives up. Without an inventory, they can claim it was working perfectly. For a more detailed look at how repair responsibilities work, see our tenant rights guide.
What to do:
Insist on a signed inventory before you hand over any money. Walk through every room with the landlord or their representative.
Photograph everything: walls, floors, appliances, windows, bathroom fixtures. Include close-ups of any existing damage.
Note serial numbers or model numbers of major appliances (washing machine, fridge, boiler). If one breaks, this proves it was the original unit.
Send the signed inventory and photos to the landlord by email so there is a timestamped digital record. For advice on how to communicate effectively with your landlord, see our communication guide.
Do the same process when you move out. Comparison photos taken at move-in and move-out are the strongest evidence in a deposit dispute.
Your contract is your safety net
Spanish rental law gives tenants more protection than most people realise, but those protections live and die in the contract you sign. The five-year minimum, the deposit cap, the IRAV rent limits, the void clauses: these exist because the law treats housing as something more than a market transaction. The question is whether you know about them before you sign, or only after something goes wrong. Take the time to read every clause, push back on anything that does not look right, and document everything from day one. If you want help making sense of your specific contract, Rent AI can walk you through it clause by clause.
