Kaucja przy najmie — zasady i zwrot

The deposit is one of the basic mechanisms protecting the landlord. It is a financial buffer in case the tenant damages the flat, fails to pay rent or leaves behind unpaid bills. Well-drafted deposit provisions, however, also protect the tenant against unjustified deductions.

In this article we explain how to set the deposit amount, how to settle it correctly and by what deadline it must be returned. We also suggest how a protocol and documentation help avoid conflicts at move-out.

Key takeaways
  • The deposit is security for the landlord's claims under the lease contract, for example overdue rent or damage that goes beyond normal wear and tear.
  • In an occasional lease the law limits the deposit to a maximum of six times the monthly rent; in an ordinary lease the parties agree it freely.
  • The deposit is returned after the lease ends, after deducting any amounts due, usually within the deadline set in the contract.
  • The handover protocol is key to a fair settlement of the deposit and to avoiding disputes over the condition of the flat.

What a deposit is and what it secures

The deposit is a sum paid by the tenant to secure the landlord's claims arising from the lease contract. It may cover overdue rent, unpaid utilities, the cost of repairing damage that exceeds normal wear and tear of the premises, and also cleaning when the flat is handed back in a grossly poor condition. It is neither an advance towards rent nor an additional fee for the landlord.

It is important to describe precisely in the contract what the deposit may be used for. Clear rules limit later disputes and give both parties a sense of predictability.

How much the deposit is

In an ordinary lease, the regulations do not impose a rigid limit, so the amount of the deposit is a matter of negotiation. In market practice it most often equals one or two months' rent. Too high a deposit can be a barrier for tenants and lengthens the search for one.

It looks different in an occasional lease, where the law limits the deposit to a maximum of six times the monthly rent. When setting the amount, it is worth taking into account the standard of the flat's fittings — the more expensive the equipment and finish, the more justified a higher security.

How to settle the deposit correctly

The basis for a fair settlement is a handover protocol drawn up when the tenant moves in and when they move out. Comparing the two protocols allows you to establish which damage arose during the lease and which existed earlier. Photographic documentation is very helpful here.

The landlord may deduct from the deposit only real, documented costs. You must not charge the tenant for so-called normal wear and tear, that is, natural traces of use, such as minor scratches on the floor or wear on the walls after years of living there. It is worth presenting the settlement in writing with an itemisation of individual items.

Deadline and method of refund

The deposit is refunded after the lease ends and the premises are handed over, after deducting any amounts due. It is best to specify the refund deadline directly in the contract, for example by indicating the number of days from the handover of the flat. If the contract is silent, general rules apply, and the tenant may demand a refund without undue delay.

The refund should take place in the same form in which the deposit was paid, most often by bank transfer. It is worth keeping the transfer confirmation and the signed settlement in order to close the matter beyond doubt.

The most common deposit disputes

Conflicts most often concern the assessment of what is normal wear and tear and what is damage. Another source of disputes can be the lack of a protocol at move-in, which makes it hard to establish the flat's initial condition. It also happens that the landlord delays the refund or deducts costs without an itemisation.

To limit the risk, draw up detailed protocols, document the state of the premises with photos and always present the settlement in writing. Transparency of action protects both parties and is usually enough to avoid the court route.

Summary: how to handle the deposit safely

The deposit is an effective security, provided it is described correctly in the contract and settled on the basis of reliable documentation. Set its amount appropriately to the standard of the flat, clearly indicate what it may cover, and remember the protocols at every handover of the premises. A timely, documented refund builds trust and closes the lease without conflict, which is beneficial for both landlord and tenant.

Frequently asked questions

Can the landlord keep the entire deposit?
Only when documented amounts due and repair costs exhaust its value. The owner may not keep the deposit without grounds or charge the tenant for normal wear and tear. They should present the settlement in writing with an itemisation.
How much is the deposit for renting a flat usually?
In an ordinary lease it is most often the equivalent of one or two months' rent, agreed through negotiation. In an occasional lease the regulations limit it to a maximum of six times the monthly rent.
Can the deposit be used for the last month's rent?
Not without the landlord's consent. The deposit is security, not an advance towards rent, so the tenant should not unilaterally decide to use it for the last month. Settlement takes place only after the lease ends and the premises are handed over.
By what deadline must the deposit be returned?
Best within the deadline written into the contract, for example a few to several days from handing over the flat. If the contract does not specify a deadline, the refund should take place without undue delay after settling any deductions.
What if there was no protocol at move-in?
It is then harder to show that the damage arose during the lease. The burden of establishing the condition falls mainly on the landlord, and doubts work in the tenant's favour. That is why a protocol and photos at every handover of the premises are so important.
