Rent Increase – When It’s Allowed and How to Defend Yourself
Imagine finding a letter from your landlord in your mailbox one day: “From next month, your rent will increase by CZK 3,000.” You might immediately think – they can’t just do that! And you’d be right: the law sets clear rules for when and how rent can be increased. If the landlord fails to follow the proper procedure, you have a strong position to challenge it.

Clients often ask me: “Can my landlord raise my rent just because they think I’m paying too little?” or “Do I have to agree if I get a letter about a rent increase?” In practice, I see landlords frequently acting incorrectly – and tenants end up paying more than they should. I’m writing this article so you know your rights and can stop any unlawful increase before it affects your budget.
What you’ll learn in this article
The legal rules for rent increases.
The maximum allowed rent increase.
The procedures for increasing rent.
How to defend yourself if your landlord breaks the law.
How rent can be increased under the law
The Czech Civil Code recognises several possibilities:
Mutual agreement – possible at any time if both tenant and landlord agree.
Unilateral increase – only if the following conditions are met:
a maximum of 20% over three years,
a written proposal stating the new amount and reasons,
proper delivery to the tenant.
Inflation clause – if included in the rental agreement.
Maximum rent increase
Without your consent, the landlord may only propose an increase up to the locally usual rent and no more than 20% over the past three years.
How to defend yourself
Don’t sign immediately – have the proposal reviewed first.
Refusal – if you disagree, the landlord can ask the court to determine the rent.
Check the reasons – verify whether the landlord has provided evidence, such as a comparison with locally usual rents.
Example from practice
A tenant in Prague received a proposal to increase rent by 30% citing “inflation.” There was no inflation clause in the agreement, and the landlord provided no comparison with locally usual rents. After a legal notice was sent, the landlord withdrew the proposal.
Lawyer’s recommendation
Do not ignore a rent increase notice – strict deadlines apply to your response. The right reply, backed by legal reasoning, can save you thousands of crowns every year.
