Rent reduction: these are the criteria for compensation for housing loss

The rent reduction and its amount depend on the interpretation of the law and general practices, which you should read to safeguard your rights in the event of a housing problem in a rented property.

Which housing difficulties entitle the tenant to a rent reduction, and what is the landlord's view on this? To what extent does the landlord determine the realisation and amount of the rent reduction? Do the recommendations of the Consumer Disputes Board have to be followed and is it worth taking legal action in case of disagreement?

A rent rebate is compensation for the period of housing damage, i.e. when the rented accommodation is not in the condition required by the contract or by law. It is the tenant's right under the law and the landlord's obligation to give it. However, the realisation and amount of the rent reduction is still a grey area, which it is essential to identify in order to protect your interests.

There are not many, even implicit, references to rent reduction in the law. Therefore, we interpreted the rent reduction in a clear form of application of the law and practice. We list the grounds for a rent reduction, and discuss the resolution of disputes between landlord and tenant, with examples from the Consumer Disputes Tribunal.

The law on rent reduction and the obligations of the parties

Act 481/1995 on the renting of residential apartments defines the tenant's right to a rent reduction. The landlord's obligation to grant a rent reduction and the amount of the reduction are mainly based on the law and the lease. The law and its interpretation are formulated in this section as either the landlord's or the tenant's obligations, in order to avoid, for example, repeating the landlord's obligations as tenant's rights. Landlord's obligations

In relation to the rent reduction, the landlord is obliged to:

  • (§ 26 to draw up the terms of the lease in such a way that they do not restrict the tenant's right to use the apartment or to require the agreed condition. Otherwise these conditions are null and void, which ensures that the tenant's rights, such as the right to a reduction in rent, are not unreasonably restricted.
  • (§ 20) maintain the accommodation in such a condition that the tenant can reasonably expect it to be of the agreed or legal standard. If the deficiencies are not due to the tenant's negligence, the landlord is obliged to grant a reduction in rent, a release from rent or even the possibility for the tenant to terminate the lease.
  • (§ 21): inform the tenant of the maintenance, repair or alteration work with a six-month warning. If it is necessary to carry out an operation essential for the maintenance of the dwelling, it may be done with at least 14 days' notice, provided that it does not cause the tenant significant inconvenience. It may also be carried out immediately if the work cannot be postponed without damaging the dwelling. Depending on the measure, it may entitle the tenant to a rent reduction. 

Article 23 on the obligations of the landlord is confusing for many as the only article that refers to a reduction or exemption from payment of rent when the dwelling is in a state of disrepair or even uninhabitable.

  • (§ 23) , the landlord is obliged to ensure that the repair or alteration work carried out by him or on his initiative (see § 21 and § 22) does not cause the tenant more harm than is necessary to carry out the work.
  • (§ 23) is interpreted as meaning that works carried out by the landlord in practice also include residential nuisances independent of the landlord, such as plumbing or façade renovations in a housing association(KKV).
  • (Article 23): the landlord is not obliged to reduce the rent if the deteriorated condition is due to the tenant's negligence or damage caused by him.
  • (§ 23): the landlord must ensure that the repair or alteration work carried out does not cause the tenant any greater inconvenience than necessary. For example, by not limiting the total duration of the renovation to a longer period than necessary, or to evenings when the tenant's daily life and rest would be more disturbed.

In summary: The landlord must keep the apartment in the agreed condition and ensure that no work causes unnecessary inconvenience to the tenant. He is obliged to give timely notice of planned works and to grant a reduction in rent for any substantial damage to the dwelling, unless it is due to the tenant's own negligence.

Tenant's obligations

The tenant's obligations include:

  • (§ 22) give the landlord access to the leased property to inspect its condition. If the loss of accommodation is due to the landlord's refusal to grant access, the tenant is not entitled to a rent reduction.
  • (§ 24) immediately inform the landlord of any defects or deficiencies in the apartment which he/she discovers and for which the landlord is responsible. The landlord has the right to try to remedy the situation from the moment of receipt of the notice of defect before being obliged to give a rent reduction.
  • (§ 25) use the apartment with care and comply with the terms of the lease. If the damage is caused by the tenant's actions, he is not entitled to claim a reduction of the rent for the period in question.
  • (not directly in the article, but in practice) must take care not to cause or contribute to damage contrary to the terms of the lease, as his or her failure to do so may result in the rent reduction right not being applicable for the period in question.
  • (not directly in the section, but in practice) for a rent reduction or other compensation, document the deficiencies in the apartment (e.g. with photographs or expert reports) to ensure that any claim for a rent reduction is based on verifiable facts.

In summary: The tenant must allow the landlord access to the property for inspection and must immediately report any defects and deficiencies and, if a rent reduction is required, document them. If the defects and deficiencies, or the failure to report them, result in a housing handicap, the tenant is not entitled to a rent reduction for the duration of the handicap.

Importance of the lease for rent reduction

The conditions agreed in the rental contract determine the condition of the dwelling, the level of equipment and other essential aspects at the start of the tenancy. Any subsequent defects or disturbances, i.e. housing problems, are compared with the conditions and the law.

If the dwelling's usability deteriorates significantly compared to what was agreed in the contract, the tenant has the right to demand that the rent be reduced to reflect the actual usability of the dwelling. For example, the tenancy agreement provides for a certain temperature, but there is a persistent, verifiably lower indoor temperature in the dwelling.

The grounds for rent reduction are called housing costs

Based on the legislation and a case-by-case analysis, a reasonable rent reduction is determined according to the extent to which the dwelling has become less usable.

The criteria for rent reduction can be divided into the following categories:

  • Major renovations: plumbing or façade renovation, during which the entire apartment is disrupted or cannot be occupied at all.
  • Health hazards: temperature too cold or hot, poor ventilation, mould, dust, radiation, noise pollution (other than from neighbours), or other health hazards that substantially affect the comfort of the dwelling.
  • Restrictions on use: premises, equipment or systems - often related to renovations, but also to damage to the home, such as water damage. If only a particular room, space or equipment such as a shower or toilet is unusable (e.g. kitchen or bathroom). Or e.g. continuous water or power cuts.

The landlord has the right to try to remedy the situation from the moment he receives the notice before he is obliged to give a rent reduction.

Extensive renovations in a housing company

Plumbing repairs typically cause the most damage to housing of all.

  • Reason: water and sewerage service interruptions, bathroom closures and possible additional problems such as damp damage.
  • Estimated rent reduction: 20-50% rent reduction (Consumer Disputes Board) for the period in question, if the renovation has led to a substantial deterioration in the usability of the dwelling.
  • Note: Full rent waivers may be possible if the property cannot be used at all.

Façade renovation is the most common type of external disturbance that affects the dwelling.

  • Reason: disturbances caused by scaffolding, noise and dust; for example, covering windows or blocking ventilation.
  • Estimated rent reduction: the reduction can be significant, but it is usually lower than the reduction due to interior renovations, for example 10-30% (Consumer Disputes Board)..

Elevator renovation is generally less inconvenient, but its impact is clear and therefore commonly replaced.

  • Rationale: Not directly affecting the internal usability of the dwelling, but always affecting the overall comfort, especially in the upper and middle floors of the building.
  • Estimated rent reduction: the rent reduction for elevator renovation is usually around 10% (Consumer Council)..

Room-specific renovations

Kitchen renovation: justified, as it directly affects everyday living comfort, especially cooking.

Bathroom renovation: justified if the use of the toilet or shower is restricted, not in the case of surface renovation

Balcony renovation: generally speaking, justified.

Temporary apartment for renovation

Full exemption from paying rent due to renovation is possible only if the property cannot be used at all. For example, in the event of water damage or extensive plumbing repairs, where the dwelling is completely unusable. The rent exemption depends on the duration of the renovation. A few days of inactivity entitle the tenant to an equivalent period of rent-free use

If repairs or other circumstances make the rental property uninhabitable, the landlord should try to arrange a replacement, in line with good tenancy practice. However, the law does not oblige them to provide replacement accommodation. This means that the situation is flexible: the landlord can offer a replacement dwelling, but the tenant can make his or her own decision whether to accept it.

There are a number of options for temporary accommodation, such as short-term rental accommodation, hotel rooms or other temporary accommodation that can be offered by the landlord or property management after negotiation. For example, if a plumbing repair is imminent and the use of the dwelling is significantly disrupted, the landlord may offer the tenant temporary accommodation.

Health hazards

Cold housing: if your home stays too cool, i.e. falls below 18°C, your comfort will be reduced and health risks may increase. Many tenancy guidelines stress that persistent coldness entitles the tenant to claim a rent reduction. As an example of the amount of the discount, in Helsinki city apartments the estimated discount percentage is 10-15% of the rent, depending on the duration of the disturbance and other conditions in the apartment.

A hot home: indoor temperatures above 32°C can also reduce the usability of your home and cause health problems, especially in summer. In this case, the tenant can claim a rent reduction for the days when the temperature in the dwelling is mostly above this limit. According to the Finnish Tenants' Association, the reduction percentage is around 10-20% of the rent.

The following also qualify for a rent reduction, but they must be measurably significant.

  • Mould problems: entitlements
  • Excessive humidity: justify
  • Indoor air pollutants (dust, allergens).
  • Noise nuisance not due to external disturbance: Entitles to

Proof of damage to housing

Ideally, the landlord and tenant will reach an agreement on the housing problem based on a brief explanation and/or a couple of pictures. Sometimes more thorough evidence is needed to establish that the housing disadvantage is sufficient to justify a rent reduction and the amount of the rent reduction requested.  

  • Testimonies: written or oral testimonies from residents or neighbours confirming, for example, persistent disturbances (e.g. excessive noise, ventilation problems or other environmental nuisance) and their impact on the use of the dwelling.
  • Photographic and audio recordings: visual or audio material that illustrates disturbances or structural defects - for example, repeated noise disturbances, water damage or other physical defects that prevent normal use of the dwelling.
  •  Expert reports and inspection reports: reports by a building, health or other expert stating that the condition or circumstances of the dwelling do not allow normal living conditions. Such reports can be particularly persuasive evidence.

Dispute resolution through the Consumer Disputes Board

If there is a dispute about a rent reduction even after proof has been provided, the parties can turn to the Consumer Disputes Board, whose role is well known. The panel will assess the reasonableness of the rent and the actual usability of the dwelling, and make recommendations on the rent at which the contractual relationship should continue in times of disturbance.

  • The Board's assessment emphasises the importance of evidence such as expert reports, photographs and witness statements in assessing the deterioration of the habitability of the dwelling. This ensures that claims are based on objective evidence.
  • The recommendations of the Consumer Disputes Board are not legally binding, but often provide a concrete starting point for negotiations between the parties. Negotiations can help to find a solution that reflects the actual condition of the dwelling and ensure that the tenant does not have to pay an unreasonably high rent during a period of disturbance.

The Consumer Disputes Board can therefore provide additional clarity and objective assessment in situations where negotiations between the parties do not lead to a common solution on the rent reduction. This process helps the parties to ensure that the rent remains reasonable in line with the actual utility of the dwelling.

Consumer Disputes Board and legal actions

If there is a dispute about the rent reduction even after the evidence has been presented, the parties can refer the matter to the Consumer Disputes Board. The panel will assess the reasonableness of the rent and the actual usability of the dwelling, and make recommendations on the rent at which the contractual relationship should continue during periods of disturbance.

Examples of Consumer Disputes Board decisions

Case 1: The tenant received a refusal decision

Landlord's bathroom renovation caused significant inconvenience to tenants, as the bathroom was completely unusable for about 1.5 months during the renovation. As a result, tenants had to store their belongings in the hallway, there was extra noise, temperatures rose considerably and the toilet/shower facilities provided in other rooms were very far away.

The tenants were refunded 70% of the rent for a short week due to the lack of a shower, 40% for about a week when an outside toilet and shower were used, and 5% for the entire renovation due to the fact that toiletries had to be stored in the hallway.

The tenants are demanding a refund of two months' rent for the entire renovation, as they claim that the previous refund of around €700 was not enough to cover the damage caused. 

However, the landlord had taken appropriate measures to minimise the situation: the tenants were offered a replacement apartment and temporary toilet/shower facilities were provided during the renovation. The Board considered that the landlord's actions were in accordance with the law and good building practice and no further compensation was required.

Case 2: The tenant received a positive decision

One room in the apartment was completely unusable due to a water leak in the roof, for which the tenant claimed an additional compensation of EUR 2 083,07 in the form of a rent reduction for that period. He had already reported the problem in May 2006, but the landlord did not take remedial action until February 2008, when it was discovered that the water leaks were causing persistent dampness, odours and allergic symptoms. The space could only be used for storage, which made it difficult to live there normally.

In addition, the calculation of the compensation was based on the fact that the rent for the 10 m2 area in question should be refunded because the usability of the apartment had been significantly impaired. The tenants argued that the compensation already granted by the landlord did not cover all the disadvantages suffered, as the space was subject to long-term occupancy problems and the tenants had to store their belongings in the hallway, which restricted their mobility.

The Board found that the right to rent reduction was determined by the extent to which the normal use of the dwelling was temporarily disrupted. Although the landlord attempted to minimise the inconvenience by providing a substitute accommodation and temporary toilet/shower facilities, it was found that these measures did not cover the long-term inconvenience experienced by the tenant. The claim for additional compensation was therefore considered justified.

Legal action as a last resort

If the landlord does not decide to give a rent reduction after the Consumer Disputes Board's decision, the tenant loses. So, in practice, the party who takes the dispute to court is always the tenant. If the Consumer Disputes Board has sided with the landlord, it is unlikely that the court will rule in favour of the tenant.

Remember that before taking legal action, the tenant must first have documented the problems in the home and reported them in writing to the landlord as soon as possible, and typically have already tried the help of a consumer dispute board. Ultimately, the tenant can take the matter to court, the claim should be brought in good time - before the tenancy ends. Once the tenancy ends, the right to claim a rent reduction usually lapses, and there is no ex post procedure.

Rent reduction checklist

  • The tenant's right to a rent reduction is based first on the law, then on the lease and finally on general practices regarding the deterioration of the dwelling.
  • In principle, the tenant's right to a rent reduction will automatically take effect if the use of the accommodation is restricted or if there is a significant disruption to the tenant's living conditions, as long as these are proven.
  • In practice, the realisation of a rent reduction depends on the clarity of the housing problem, the landlord and the tenant's willingness to resort to the Consumer Dispute Board or legal action.
  • The amount of the rent reduction varies widely, as it is decided on a case-by-case basis after negotiations between the tenant and the landlord. When negotiating, compare information from several sources to make the best decision for your interests.
  • Clear and quantifiable housing damage is easy for the tenant to prove, such as damage to specific rooms and equipment (kitchen renovation, lack of shower) or easily documented by the tenant (visible mould, damp damage). The most common and easiest method of calculation is the square metre affected by the housing loss.
  • The right to a rent reduction does not arise, at least if the cause of the deterioration is not due to the tenant's own negligence or other damage caused by him, such as water damage caused by a leak in a dishwasher fitting he installed himself.
  • Disputes can be settled by expert advice, if necessary by a consumer dispute panel and ultimately by legal action.

It is in the interest of both parties to find a joint solution that maintains the contractual relationship but changes the rent to reflect the actual occupancy of the dwelling for as long as the housing problem persists.
