Finland rental security deposits are intended to protect landlords against unpaid rent, damage to a property and certain other obligations under a tenancy agreement, but they are not a payment that landlords can automatically keep when a tenant moves out. For renters leaving an apartment, the difference between legitimate deductions and unjustified withholding can determine whether hundreds or even thousands of euros are returned.
The deposit is often one of the largest upfront costs of renting a home in Finland. A tenant moving into an apartment with monthly rent of EUR 900, for example, could be asked to provide EUR 1,800 as a two-month deposit. That money may remain tied up throughout the tenancy, making its return particularly important for people who need to finance another home, cover moving expenses or settle into a new city.
Finnish rental law places limits on the amount landlords can demand and recognises that tenants should not be held financially responsible for the ordinary deterioration that comes with living in a property. The Consumer Ombudsman and Consumer Advisory Services, operating under the Finnish Competition and Consumer Authority (KKV), provide guidance on rental disputes, including disagreements over security deposits. The precise rules can depend on the tenancy agreement and when it was concluded, so tenants should check the legislation applicable to their contract.
For most residential rentals, the security deposit cannot exceed the equivalent of three months’ rent. A landlord may request a smaller amount, and the deposit is commonly equivalent to one or two months’ rent. The legal ceiling is not a requirement to charge three months, nor does it give landlords an automatic right to retain the entire sum if a dispute arises.
The deposit may be paid into an account designated by the landlord or into a separate rental security account, depending on the arrangement. Other forms of security, such as a guarantee, may also be used. Whatever the arrangement, tenants should establish exactly what has been agreed before transferring money. The rental agreement should make clear the amount, how the security is provided, which obligations it covers and the conditions for its release.
This is especially important for people renting from private landlords for the first time. A tenant may be focused on securing a home, arranging electricity and internet contracts, and organising a move, but the terms governing the deposit deserve the same attention as the monthly rent. Keeping a signed copy of the agreement and proof of payment can prevent uncertainty later.
The most common disputes emerge when the tenancy ends. A landlord may have legitimate grounds to deduct money for unpaid rent, damage caused by the tenant or inadequate final cleaning where the tenant was responsible for leaving the property clean. Depending on the agreement and the circumstances, other unpaid obligations covered by the security may also be relevant. However, a landlord cannot simply treat the deposit as additional income or use it to pay ordinary expenses unrelated to a tenant’s responsibility.
Normal wear and tear is a particularly important distinction. Floors become worn through everyday use, surfaces age and minor signs of occupation accumulate over time. These changes do not automatically constitute damage for which a departing tenant must pay. A landlord must distinguish between ordinary deterioration and damage attributable to the tenant’s actions or negligence. A broken fixture caused by careless use, for example, is different from an ageing fixture that has reached the end of its useful life.
The age and condition of the property also matter when assessing a claim. A tenant should not automatically be expected to finance the replacement of an old surface or appliance at the full cost of a new one simply because it shows signs of use. The circumstances, the nature of the damage, the property’s previous condition and the reasonable cost of putting matters right can all affect whether a deduction is justified.
Cleaning is another frequent source of disagreement. Leaving an apartment dirty can result in a legitimate claim if the tenant was required to carry out the final cleaning and failed to do so. But the existence of a cleaning charge does not, by itself, prove that the entire deposit can be withheld. The landlord should be able to explain what was left undone, what work was necessary and how the amount charged was calculated.
Evidence gathered before and after the tenancy can make a substantial difference in these disputes. At move-in, tenants should photograph existing marks, damaged fittings, stained surfaces and any other defects. They should retain the inspection report, if one is provided, and notify the landlord in writing of problems that were not recorded. Photographs should be dated where possible and kept alongside correspondence and the rental agreement.
The same approach should be used when moving out. Photographs showing the apartment’s condition after cleaning, a record of returned keys and written confirmation of the handover can help establish what was left behind. Receipts for professional cleaning or repairs may also be useful. These records are not merely administrative details; they can help establish whether a later demand for payment reflects actual damage or a condition that existed before the tenant moved in.
Under the rules taking effect on 1 October 2026, the landlord must return or release the security without delay and no later than 14 days after the tenancy ends or the tenant gives up possession of the property. If a justified obstacle prevents the return, the deadline runs from when that obstacle ceases to exist, subject to the requirement to act without delay. The landlord must also provide written notice within the applicable deadline if the security is being withheld, explaining the basis of the claim and a reasonable estimate of its amount.
The timing matters for tenants moving out around the date the new rules take effect. The Finnish Competition and Consumer Authority’s guidance on security deposits specifically states that its information is based on legislation entering into force on 1 October 2026. Because the law has changed, renters should check which provisions apply to their individual tenancy rather than assume that every detail is identical for contracts made earlier.
When a landlord intends to deduct money, a vague message claiming that the apartment was not in satisfactory condition should not end the discussion. Tenants should ask for a sufficiently detailed explanation, including the reason for each deduction and supporting information about the work, materials or unpaid obligation involved. A cleaning invoice, repair estimate, photographs or other relevant records can help establish whether the amount is reasonable. Under the rules taking effect in October 2026, the landlord must explain the grounds for withholding the security and provide a reasonable estimate of the claim.
A disputed deduction does not necessarily mean that the tenant is entitled to every euro immediately, but neither does the landlord’s decision settle the matter. If only part of the deposit is genuinely in dispute, the tenant should ask for the undisputed balance to be returned rather than accept an unexplained hold on the entire amount. The applicable rules for withholding money while a claim is being assessed should be considered in light of the specific circumstances and the type of security arrangement.
One mistake tenants should avoid is withholding their final rent payment because the landlord already holds a deposit. The two obligations should not be treated as interchangeable. Rent remains payable according to the tenancy agreement, and a tenant who stops paying it without a proper legal basis may create the very arrears that the deposit is intended to cover. Anyone who believes that a landlord owes them money should pursue the deposit separately and keep rent payments up to date.
If the agreed return date passes without payment or a satisfactory explanation, the tenant should contact the landlord in writing. The message should identify the tenancy, state the amount of security paid, give the date the tenancy ended and request repayment by a reasonable deadline. If the landlord claims deductions, the tenant should ask for an itemised explanation and supporting evidence. Written communication creates a record of the dispute and makes it easier to show what was requested and how the other party responded.
Where the landlord refuses to resolve the issue, KKV’s Consumer Advisory Services can provide guidance on the next steps. There is an important distinction, however, between renting from a business and renting from a private individual. The Consumer Advisory Services cannot investigate or mediate a dispute against a private landlord in the same way it can handle consumer disputes involving businesses, although it can offer general advice. The Consumer Disputes Board can consider many rental disputes between private individuals, but its role and the available remedies differ from those of a court. Tenants should check the appropriate procedure for their circumstances and consider legal advice if the amount at stake is substantial.
The Finnish legal system also provides routes for pursuing a civil claim where necessary. Tenants should preserve the rental agreement, payment records, inspection documents, photographs, messages and any invoices or estimates relevant to the dispute. A clear file of evidence can be more persuasive than a long exchange of angry messages, particularly when the disagreement concerns the cost of repairs or the difference between normal wear and actual damage.
The practical lesson begins long before the moving van arrives. Tenants should read the security clause before signing, document the apartment’s condition at the start, report defects promptly, comply with their cleaning obligations and arrange a clear handover at the end. Landlords, in turn, should assess claims fairly, distinguish ordinary wear from tenant-caused damage and explain any deductions rather than relying on general allegations.
A rental deposit is a safeguard, not a penalty for leaving a property. For tenants in Finland, understanding that distinction can make the process of moving home less stressful and help prevent legitimate claims from becoming costly disputes. When the apartment has been returned in the agreed condition, rent and other covered obligations have been settled, and no justified deduction remains, the deposit should not become a prolonged argument. It is money provided as security, and its return should follow the agreement and the law.
