A rental agreement in Czechia comes in two forms: nájem — a direct contract with the property owner, which gives the tenant strong protection under the civil code, and podnájem — a sublease arranged through the primary tenant, where protection is minimal. Before signing, check the owner in the cadastre, the size of the deposit (kauce — no more than three months' rent), the rules for rent increases and termination periods, and draw up a protokol when the keys are handed over.
The difference between nájem and podnájem isn't a technicality — it determines a genuinely different scope of rights: how much notice you can be given to move out, whether your deposit will be returned, and whether you'll receive a document proving housing for your residence permit renewal. Here's what a 2026 rental agreement must contain, which clauses are void, and what to check before you sign.
A nájemní smlouva is signed directly with the owner (pronajímatel). The civil code (občanský zákoník, § 2235 et seq.) protects the tenant as the weaker party: clauses that curtail their statutory rights simply don't apply, even if you signed them. A tenant can only be evicted for reasons explicitly listed in the law, generally with three months' notice.
A podnájemní smlouva is signed not with the owner but with the tenant who is themselves renting the flat. This is a derivative right: if the underlying nájem ends, the podnájem terminates automatically — regardless of what your sublease agreement says. The civil code's protective provisions for residential leases don't extend to podnájem: termination conditions and rent increases are governed primarily by the text of the contract itself.
| Parameter | Nájem | Podnájem |
|---|---|---|
| Contract is with | the owner | the flat's tenant |
| Civil code protection | full — unfavorable clauses are void | minimal — whatever the contract says applies |
| Eviction | only for legal reasons, usually 3 months' notice | per contract terms; ends together with the underlying nájem |
| Rent increases | limited by law | as stated in the contract |
| Housing document for residence permit | the contract itself | owner's confirmation often required |
If the tenant themselves permanently lives in the flat and only rents you a room, the owner's consent isn't required. If they rent out the whole flat and don't live there themselves, written consent from the owner is mandatory. The request must be submitted in writing; if the owner doesn't respond within a month, consent is deemed granted — but this rule doesn't apply if the underlying contract explicitly prohibits subletting (§ 2275). Podnájem without the required consent is a serious breach of contract: the owner is entitled to terminate the underlying nájem, leaving you without housing. So before signing a sublease, always ask to see the underlying contract and the owner's written consent.
A residential lease must be in writing. Make sure the text includes:
Under § 2254, the deposit (kauce, referred to as jistota in the code) cannot exceed three times the monthly rent, excluding services. Contractual penalties (smluvní pokuty) count toward the same cap: combined, kauce and penalties cannot exceed three months' rent. The law doesn't specify an exact deadline for returning the deposit after move-out — spell it out in the contract, typically up to one month. The tenant is also entitled to interest on the deposit amount at no less than the statutory rate.

If the contract has an inflation clause (inflační doložka), rent rises once a year according to the agreed index — usually the ČSÚ inflation rate. If the contract says nothing about increases, § 2249 applies: the owner may propose in writing to raise rent to the level of comparable rentals in the area, but no more than once every 12 months and by no more than 20 percent cumulatively over the last three years. You have two months to agree in writing; without your consent, the owner can only go to court — they have three more months to do so, and cannot unilaterally rewrite the price. If rent is eating into a big chunk of your budget, check whether you're eligible for the housing allowance příspěvek na bydlení.
The tenant is responsible for routine upkeep (běžná údržba) and minor repairs (drobné opravy) under government regulation č. 308/2015 Sb. From January 1, 2026, the limits have been raised: a repair counts as minor up to 1,500 Kč per instance (previously 1,000 Kč), and the annual cap is 150 Kč per square meter of floor area (previously 100 Kč). For a 60 m² flat, that's a maximum of 9,000 Kč a year; anything above the limits is paid by the owner. Another change for 2026: travel and callout costs for a repair technician are billed to the tenant separately and don't count toward the annual cap. Major breakdowns — the boiler, wiring, risers — are always the owner's responsibility: report them in writing and keep the correspondence.
Advances for water, heating, and waste collection are listed as separate line items and reconciled once a year against actual usage. Electricity and gas are more often transferred directly into the tenant's name — see our guide on utility bills and energy for how that works.
| Situation | Notice period |
|---|---|
| Tenant, indefinite-term contract | 3 months, no reason required |
| Tenant, doba určitá | early termination — only for a substantial change in circumstances or by mutual agreement |
| Owner — legal grounds (flat needed for their family, serious breach of contract) | 3 months, in writing and with a stated reason |
| Particularly serious breach (rent/service arrears of 3 months or more) | no notice period — must move out within a month |
The notice period runs from the first day of the month following delivery of the notice. The owner's výpověď must be in writing, state the reason, and explain your rights: you have two months from receipt to challenge it in court. Useful detail: if you keep living in the flat for three months after a doba určitá ends and the owner hasn't demanded in writing that you leave, the contract is automatically extended for the same term, up to a maximum of two years.
A contract for years ahead, unusual penalties, or pressure to "sign today" are all reasons to have the text reviewed by a specialist before signing: lawyers can help in a single consultation. And if you're still searching for a place, start with our guide on where to look for a flat in Prague.
The předávací protokol is an attachment to the contract that records the flat's condition at move-in and move-out: electricity, gas, and water meter readings, an inventory of furniture and appliances, defects, and the number of keys. Photograph everything, including small scratches and stains, and insist that any issues be noted before you sign. Without a protokol, it's nearly impossible to prove damage existed before you moved in — and that's exactly what owners cite when withholding the kauce at move-out.
Only by agreement with the owner or in the event of a substantial, unforeseeable change in circumstances — for example, relocating for a job that couldn't have been anticipated. A practical solution is to arrange a replacement: you find a new tenant, and the parties sign a termination agreement (dohoda o ukončení nájmu).
No. A clause banning registration of your residence address is void. With a direct nájem, the contract itself serves as proof of housing; with podnájem, check with OAMP in advance about what document you'll need from the owner.
No. For the duration of the lease, the flat is for your exclusive use; an inspection is only possible with reasonable advance notice. The owner changing the locks or visiting unannounced is a breach that can be challenged.
The owner can't invoke the lack of a written contract against the tenant — meaning they can't kick you out "because there's no paperwork." But without a document you won't be able to prove housing for your residence permit or the agreed terms — always insist on a written contract.
Nájem transfers to the new owner along with the flat: the parties' rights and obligations remain unchanged, and the sale itself is not grounds for eviction. When the owner changes, ask for written confirmation that the kauce has been transferred to the new owner along with the flat.
No — unilaterally offsetting the kauce against rent is a breach of contract: the deposit is settled after the flat is handed over and its condition is checked against the protokol. If you're worried about getting your deposit back, document the flat's condition with photos and a protokol — that leaves the owner no grounds to withhold the money.
Always nájem: full protection under the code, predictable timelines, and documents for immigration procedures. Podnájem is acceptable for a room or a short stay, but check the chain of consents — otherwise your housing depends on someone else's contract.
