Residential leases in the Czech Republic are governed by the Civil Code (sections 2235 to 2301), and the rules favour the tenant. A landlord needs to know five of them: the deposit can be at most three months' rent, you can give notice only for reasons listed in the law, a fixed-term lease can renew itself, rent increases follow a set procedure, and utility charges must be settled within four months after the billing period ends. This article reflects the law as of October 2026.
For each rule we also describe the mistake we see landlords make most often. Many owners of Prague flats live abroad, so we also point out where that makes a difference.
One principle sits behind all five rules. A lease can add to the law, but it cannot take protection away from the tenant. Under section 2235, any clause that cuts the tenant's statutory rights is simply disregarded, as if it were not in the contract at all. A clause you copied from a lease in your home country may therefore have no effect here.
What changed in 2026, and what didn't
A larger reform of Czech rental law was discussed in 2023 and 2024. Among other things it would have limited back-to-back short fixed-term leases. It never passed before the parliamentary term ended in October 2025, and as of October 2026 no new bill on residential leases is in parliament. There is still no limit on how long you can keep renewing fixed-term leases with the same tenant.
Three smaller changes took effect on 1 January 2026:
- A faster eviction order. If a lease has ended and the former tenant stays, a court can now issue an eviction order (rozkaz k vyklizení) without a hearing. The tenant has 15 days to move out or to object. You must attach a written request to vacate that you sent the tenant at least 14 days before filing. Courts are now expected to decide lease-termination disputes within six months as a rule.
- Higher limits for minor repairs. The tenant pays for minor repairs up to CZK 1,500 per repair (previously CZK 1,000), up to a yearly total of CZK 150 per square metre of floor area (previously CZK 100). The tradesperson's travel costs are paid by the tenant on top and do not count toward the limits.
- Delivery by data box. The law now presumes that a clause agreeing to deliver documents through the Czech government's electronic mailbox system (datová schránka) is reasonable. If both you and the tenant have a data box, it is the most practical way for an owner abroad to deliver a notice with proof that it arrived.
1. The deposit: at most three months' rent, including any penalty
The deposit, called jistota in Czech law, can be at most three times the monthly rent. A contractual penalty, allowed in residential leases since 1 July 2020, counts toward the same cap. The deposit and any penalty together cannot exceed three months' rent. The prevailing reading is that the cap is calculated from the rent alone, without the monthly utility advances.
In practice the cap rarely gets in the way. Deposits in the Czech market usually range from one to three months' rent, depending on the type of flat and its location.
The tenant is entitled to interest on the deposit from the day it was paid, at least at the statutory rate. The law does not say which rate that is, and the courts have not settled the question either. The best approach is to set the interest in the lease itself, although even that does not guarantee how a dispute would end under the current state of the law.
You return the deposit when the lease ends. Before returning it, you can deduct what the tenant owes you under the lease, typically unpaid rent or compensation for damage to the flat. The law sets no fixed deadline in days. Whether you may hold back part of the deposit until the annual utility settlement is not clearly settled.
The mistake we see most often: no handover protocol. Without photos, meter readings and a written description of the flat on the day the tenant moves in, you will struggle to prove the tenant caused any damage, and you end up returning the whole deposit.
2. Lease term: one year, and watch the end date
A Czech lease is either for a fixed term (na dobu určitou) or for an indefinite term (na dobu neurčitou), and the difference matters a great deal to a landlord. An indefinite lease can only be ended by notice, and only for the reasons listed in section 2288. A fixed-term lease ends on its own on the agreed date, with no notice and no reason needed.
We recommend a fixed-term lease for one year. In our experience that protects the landlord well enough. If the tenancy works, you agree with the tenant at the end of the year to continue, possibly at a new rent. If it doesn't, the lease ends and you need neither a legal reason nor a court.
A fixed-term lease can, however, renew itself. Under section 2285, if the tenant keeps living in the flat for three months after the lease has ended and you do not ask them in writing to leave during that time, the lease is renewed for the same term, up to a maximum of two years. The safest moment to deliver the request is soon after the end date, not at the end of the three-month window. If you have already filed an eviction lawsuit by then, the lawsuit takes the place of the request (Supreme Court, 26 Cdo 1082/2017).
If you want to continue with the tenant, sign a new lease or an extension before the current one ends.
The mistake we see most often: nobody tracks the end date. The tenant stays, three months pass, the lease renews for another year at the same rent, and the landlord loses a year in which they could have changed the terms or ended the tenancy. For owners abroad this happens more easily, because nobody is around to notice that the date has passed.
3. Notice: only for statutory reasons, and with the right wording
A landlord can give notice with a three-month notice period only for the reasons in section 2288. For both fixed-term and indefinite leases these are:
- the tenant seriously breaches their obligations,
- the tenant has been convicted of an intentional crime against the landlord, a member of the landlord's household, someone living in the building, or property in the building,
- the flat has to be vacated in the public interest,
- another reason of similar seriousness.
For an indefinite lease, you can also give notice if you need the flat for yourself, for a spouse leaving the household during or after a divorce, or for a close relative (parents, children, grandparents, grandchildren or siblings, yours or your spouse's). If you do not start using the flat that way within one month after the tenant leaves, without a serious reason, you must offer it back to the tenant or pay them damages.
The notice must be in writing, must reach the tenant and must state the reason. It must also tell the tenant that they have the right to object and to ask a court to review whether the notice is justified. A notice without this statement is invalid. The three months start on the first day of the month after the notice is delivered. The tenant has two months from delivery to ask the court for a review.
Notice without a notice period (section 2291) is possible only for a particularly serious breach. Typical examples are rent and utilities unpaid for at least three months, serious damage to the flat or building, serious nuisance to neighbours, or using the flat in a way or for a purpose that was not agreed. Before giving this notice, you must ask the tenant, preferably in writing, to remedy the breach within a reasonable time. Without that request the notice is disregarded. The tenant must then hand over the flat without undue delay, at the latest within one month after the lease ends.
The mistake we see most often: a notice without the statement about the tenant's right to object, or an immediate notice over unpaid rent without the prior request to pay. Either way the notice is invalid, and the landlord starts over, usually several months of rent poorer.
4. Rent increases: either a clause in the lease or section 2249, never both
There are two ways to raise the rent during a lease. The first is a clause in the lease under section 2248, typically an inflation clause or a pre-agreed stepped rent. The second is a unilateral proposal under section 2249, which applies only if the lease says nothing about rent increases.
The section 2249 procedure has fixed rules:
- The proposal must be in writing, and the new rent can be at most the comparable rent in the area.
- Increases over the last three years cannot add up to more than 20%.
- You must prove the comparable rent, either with an expert valuation or with at least three lease contracts for comparable flats. The Supreme Court has held that a proposal without this proof is invalid (26 Cdo 1650/2023).
- You cannot make a proposal earlier than 12 months after the last increase.
- If the tenant agrees, the new rent applies from the third month after the proposal was delivered. If the tenant does not confirm agreement in writing within two months, you have a further three months to go to court.
Our overview of average rents in Prague in 2026 shows what flats typically rent for by layout and district. It is a good orientation, but it is not proof for section 2249: the court wants a valuation or actual contracts.
An inflation clause looks like the easy answer, but it has a downside. In judgment 26 Cdo 1670/2018 of 22 May 2019, the Supreme Court held that an inflation clause is an agreement on rent increases, so the landlord can no longer use the section 2249 procedure. The only exception is a substantial change of circumstances that the parties could not have foreseen when they signed. Normal market movements, or market rents simply outgrowing the contract rent, do not count. In an indefinite lease, an inflation clause can tie the rent to inflation for years, even while market rents rise faster.
Our take: with a one-year lease you need neither an inflation clause nor section 2249. You set the rent again at every renewal by agreement with the tenant, and that agreement is not bound by the 20% cap or by comparable rents. Before you put an inflation clause in the lease, ask whether it will limit you more than it helps.
The mistake we see most often: an inflation clause in an indefinite lease, with the landlord counting on section 2249 once the rent falls behind the market. It will not be available.
5. Utilities: settle within four months, or pay CZK 50 a day
The monthly utility advances (water, heating, waste collection, the lift, cleaning of common areas and similar) are not your income. Once per billing period, which can be at most 12 months, you must settle them with the tenant against the actual costs. The rules are in Act No. 67/2013:
- You must deliver the settlement to the tenant within four months after the billing period ends. For a calendar year, that means by 30 April.
- Overpayments and underpayments are due within the period agreed in the lease, at the latest four months after the settlement is delivered.
- The tenant can ask for supporting documents and raise objections within 30 days of delivery. You must deal with them within 30 days.
- For every started day of delay with the settlement, the tenant can claim a penalty of CZK 50, unless your lease sets a different amount. The same penalty applies to a tenant who fails to tell you in time about a change in the number of people living in the flat.
You can change the advances during the year with a written notice that gives the reason. The new amount applies from the month after the notice is delivered.
The mistake we see most often: advances set too low to make the advertised rent look cheaper. A year later a large underpayment arrives, the tenant can't or won't pay it, and a dispute over a few thousand crowns spoils an otherwise good tenancy. If the flat is in a building run by an owners' association (SVJ), the association's statement to you falls under the same four-month rule, so it often arrives shortly before your own deadline. Owners abroad should plan for that.
Why a lease template from the internet is a risk
Free lease templates are written generically, and they often contain clauses that do not work for a Czech residential lease, such as a deposit above three months' rent, notice without a reason, or a shorter notice period. Clauses that worsen the tenant's position are disregarded, so they will not help you in a dispute. At the same time, templates usually leave out what actually protects a landlord: a handover protocol, delivery by data box, or the landlord's consent before other people move in. Translated templates from other countries are even riskier, because they follow a different legal system. We recommend having the lease checked by someone who knows Czech rental law before you sign. If it ever goes to court, the proceedings will be in Czech, so a bilingual lease with a clear rule on which version prevails saves trouble later.
Our take
Czech rental law leans toward the tenant, but it is predictable. A landlord who signs one-year leases, keeps a signed handover protocol, stays within the deposit cap and watches two dates a year, the end of the lease and the utility settlement deadline, rarely needs a court.
The 2026 eviction order shortens the road when a tenancy goes wrong, but it still means months without rent. That is why we think it pays to decide deliberately every year whether to continue with the tenant, rather than letting the lease run on by itself.
