Last October, a friend of mine — let’s call her Marta — came home to her flat in Vinohrady after a long day at work and found a letter taped to her door. Not from the postman. From her landlord. The rent was going up by 6,000 CZK a month, effective next month. No discussion, no negotiation, just a number on a piece of paper and an implied “take it or leave it.”

Marta had been living in Prague for five years. She spoke decent Czech, had a stable job, paid rent on time every single month. And yet, standing in her hallway reading that letter, she had no idea whether what her landlord was doing was even legal.

She’s not alone. If you’re an expat renting in Czechia right now, chances are you’ve either been in Marta’s shoes or you know someone who has. The rental market here is tight, prices keep climbing, and most of us signed our first lease without fully understanding what Czech law actually says about our rights as tenants.

So let’s fix that.

The Prague rent squeeze: what the numbers say

Before we get into your legal toolkit, it helps to understand what’s driving the madness. Prague’s average rent has climbed to around 475 CZK per square meter, and year-over-year growth across Czechia is running somewhere between 6% and 9%. Vinohrady, Letná, and Staré Město are the priciest neighborhoods, but even traditionally “affordable” areas are creeping up fast.

The vacancy rate in Prague sits at a brutal 1–2.5%. That means for every decent flat that hits the market, there are dozens of people scrambling to get it — and landlords know it. A typical listing lasts just 15 to 25 days before someone snaps it up.

Why is this happening? A few things at once. Wages are recovering, which means more people can pay higher rents — so landlords raise them. Home prices remain sky-high, trapping people in the rental market who might otherwise buy. And Prague keeps attracting a steady stream of workers, students, and digital nomads from all over the world, all competing for the same pool of apartments.

But here’s the thing most expats don’t realize: Czech law is not as landlord-friendly as it feels when you’re the one getting the rent hike letter.

What your landlord can (and can’t) do

Let’s start with the big one, because it’s what keeps most renters up at night: rent increases.

Under Czech civil law, your landlord cannot just decide to jack up your rent whenever they feel like it. If you’re on an indefinite-term lease, the total increase over any three-year period is capped at 20%. That’s it. If your landlord tries to push beyond that, you have legal grounds to push back.

Now, there’s a catch — and it’s an important one. If you’re on a fixed-term lease (which many expats are, typically for one year), the rules are different. When that lease expires, your landlord can propose essentially whatever rent they want for the new term. You can negotiate, of course, but they hold the cards. This is why plenty of landlords in Prague prefer short-term contracts: it gives them a reset button on pricing every twelve months.

That quote matters more than you might think. Some expats assume — or get told by less-than-honest landlords — that their rights are somehow diminished because they’re not Czech. That’s false. The Czech Civil Code makes no distinction based on nationality. If you’re a tenant in Czechia, you have the same legal protections as anyone else.

The deposit trap (and how to avoid it)

Deposits are another area where things get messy. The law caps your deposit at three months’ rent. If your landlord is asking for more, that’s illegal — full stop. You’re also entitled to annual interest on the deposit while the landlord holds it, something almost nobody claims but everyone is owed.

When you move out, the landlord has one month to return your deposit after you hand back the apartment. If they start dragging their feet, or try to deduct dubious “damages” they can’t document, you have the right to challenge it. And in 2026, the rules around minor repairs have been updated: tenants are now responsible for repairs up to 1,500 CZK per incident, with the annual total capped at 150 CZK per square meter. Anything above that is on the landlord.

The Airbnb effect: why your next-door flat might suddenly be available

Here’s where things get interesting — and potentially good for long-term renters. Czechia is cracking down hard on short-term rentals, and the ripple effects could reshape the rental market in your favor.

The new e-Turista system, which is becoming mandatory in 2026, requires every short-term accommodation provider — every Airbnb host, every Booking.com listing — to register in a central electronic system and display a unique registration number on all their listings. Fail to register? Fines of up to 100,000 CZK.

And here’s the kicker: an estimated 70% of short-term rental providers on these platforms were previously operating without any registration at all. That’s thousands of apartments in Prague alone that existed in a regulatory grey zone, paying no tourism taxes, dodging all oversight.

That’s changing fast. The Czech government is also preparing legislation that would give municipalities the power to cap the number of days per year a flat can be used for short-term rentals, restrict when and where Airbnbs can operate, and set minimum space requirements per guest. Prague’s historic center could see the most aggressive restrictions.

What does this mean for you as a long-term renter? Potentially, a lot. If hosts find it harder and more expensive to run short-term rentals, some of those apartments will shift back into the long-term market. More supply means less pressure on rents — or at least a slower rate of increase. It won’t happen overnight, but the direction is clear.

The Housing Support Act — a quiet revolution

One of the less-talked-about changes this year is the Housing Support Act, which came into effect in January 2026. It created 115 new “Housing Contact Points” across Czechia — essentially free advice centers where tenants can get legal help, mediation with landlords, and guidance on their rights.

It also introduced something called “guaranteed housing,” where the state provides financial guarantees to private landlords who rent to vulnerable tenants. If you’re an expat who’s struggled to secure a lease because landlords are skittish about renting to foreigners — and let’s be honest, that’s a real and common problem — this program could eventually make a difference, though it’s still in its early stages.

Back to Marta. After a few panicked Google searches and a call to one of those newly opened Housing Contact Points, she discovered something that changed the whole dynamic: her lease was indefinite-term. The landlord’s proposed increase — nearly 30% in a single jump — was flatly illegal. She wrote him a letter citing the relevant section of the Civil Code, and within a week, they’d negotiated a much more reasonable adjustment.

She told me afterward that the thing that bothered her most wasn’t the attempted rent hike itself. It was that she’d lived in Prague for five years and never known she had any rights at all.

Don’t be Marta. Know your rights before you need them.
