The real monthly cost of renting a flat in Warsaw

Updated 23 September 2026 · By Yahor Kuliashou (RentalAgent, Warsaw) · Sources

The full monthly cost of a Warsaw rental is usually three things: czynsz najmu (rent to the landlord), czynsz administracyjny (the building's service charge, if the lease passes it to you) and media (utilities, billed by usage). When you move in you also pay, once, a kaucja (deposit) and sometimes a prowizja (agency fee). The price in a listing's headline often shows only the first of these.

This guide explains each term, what Polish law says about it, walks through an example with invented numbers, and gives you the questions to ask before a viewing. The Polish words stay in Polish, because that's what you'll see in the listing and the contract.

The five lines that make up the price

A simple habit helps: mark every line as known (there's a figure in the listing or the lease), estimated (someone said "about") or unknown. Every unknown line is one question for the landlord. That's how RentalAgent, the service we're building, is meant to count cost too.

Czynsz najmu vs czynsz administracyjny: what's the difference?

Czynsz najmu is the rent you pay the landlord. The Polish Civil Code defines a lease this way: the landlord hands over a thing for use, and the tenant pays the agreed czynsz (art. 659 §1 KC).

Czynsz administracyjny is the everyday name for what the flat's owner pays to the owners' association (wspólnota mieszkaniowa) or the co-operative (spółdzielnia). Under the Act on Ownership of Premises, an owner shares the costs of managing the building's common property (art. 13(1)) and pays advances towards them as current monthly charges (art. 15(1)). Rental listings often show it separately because the landlord passes it on to the tenant.

One thing surprises people. The Tenants' Protection Act (ustawa o ochronie praw lokatorów) says that in a lease, besides the czynsz, the landlord may charge only "fees independent of the owner": energy, gas, water, sewage and waste collection (art. 9(5) read with art. 2(1)(8)). So the split into "rent" and "admin" is market practice, and how exactly a contract should word it is a question for a lawyer. What matters for you is the total that leaves your account each month and what it covers.

What does czynsz administracyjny cover?

The Act lists what the costs of managing the common property include (art. 14, Act on Ownership of Premises):

• repairs and routine maintenance;
• electricity, heat, gas and water for the common parts, the shared aerial and the lift;
• insurance, taxes and other public charges (unless owners pay them directly);
• cleaning;
• pay for the management board or the managing agent.

In practice, what an owner pays the association or co-op can also include advances for the flat's own heating, water or waste. It depends on the building. So "czynsz administracyjny 600 zł" tells you little until you know what's inside it. Ask: Co wchodzi w czynsz administracyjny? ("What does the admin fee include?")

Is czynsz administracyjny paid every month?

Yes. Owners pay the advances in advance, by the 10th of each month (art. 15(1), Act on Ownership of Premises). That's the owner's duty to the association. When and to whom you hand the money over is set by your lease.

Rent works in a similar way: you pay on the date in the lease. If the lease sets no date and runs for longer than a month, rent is paid monthly in advance, by the tenth day of the month (art. 669 KC).

Media: electricity, gas, internet and annual settlements

This is where most of the unknowns sit, because utilities depend on usage and on whose name the supply contracts are in.

• Prąd and gaz (electricity and gas) may stay on the landlord's contract, in which case they forward you the bills, or be transferred to you.
• Water and heating often go through the association or co-op as advances, and once a year there's a settlement: a refund or an extra payment (dopłata).
• Internet is usually a separate contract.
• Waste (odpady): ask whether it's inside the admin fee or charged separately.

One rule from the law: the landlord may charge you "fees independent of the owner" only if you don't have a direct contract with the supplier (art. 9(6), Tenants' Protection Act). And if they raise those fees, they must give you a written breakdown with the reason for the increase (art. 9(2)).

The single most useful question: Ile wyniosły media w zeszłym roku zimą? ("How much were the utilities last winter?") Winter adds heating, so this answer tells you more than "about X on average".

Kaucja: how much, at most, and when you get it back

The deposit secures whatever you owe the landlord on the day you move out. The legal caps:

• standard lease: the deposit can't exceed twelve times the monthly czynsz, at the rate on the day the lease is signed (art. 6(1), Tenants' Protection Act);
• najem okazjonalny ("occasional lease": the owner is a private individual who doesn't run a rental business, fixed term of up to 10 years): no more than six times the monthly czynsz (art. 19a(1) and (4)).

In both cases the deposit is returned within a month of the flat being vacated, minus what you owe the landlord (art. 6(4), art. 19a(5)).

These are ceilings, not typical amounts. The deposit for a particular flat is agreed with the landlord. Write down in the lease which amount it was calculated from.

Prowizja: the agency fee

If an agency lets the flat, it may charge a fee. Brokerage in real estate includes arranging lease agreements (art. 179b(3), Real Estate Management Act). The brokerage agreement must be in written or electronic form, or it's void (art. 180(3)). The agent must hold civil-liability insurance (OC), and a copy of the policy is attached to the agreement (art. 181(3) and (3a)).

The Act doesn't set the size of the fee. So ask before the viewing, not after: Czy jest prowizja? Ile wynosi? ("Is there a commission? How much?") It's worth confirming a "bez prowizji" (no commission) note by phone too.

Worked example: pricing one listing

The listing says: "2 pokoje, 3000 zł + opłaty". After a phone call you know more:

Every month: 3000 + 600 + 150 + 60 = 3810 zł, not the 3000 zł in the headline. To move in (first month of rent and admin fee, deposit, agency fee; utilities are billed later): 3000 + 600 + 3000 + 1500 = 8100 zł.

One line stays an estimate: electricity. If the heating is electric, winter can look very different. Ask about it before you sign.

How to read a listing

• "3000 zł + opłaty" or "+ czynsz": the headline is rent only. At least one line is missing.
• "3000 zł (w tym czynsz administracyjny)" (admin fee included): ask whether utilities are included too, or only the building charge.
• "media wg zużycia" (utilities by usage): the amount is unknown. Ask for last winter's bills.
• "bez prowizji": check there's no separate "contract preparation" fee or similar.
• No mention of kaucja: that doesn't mean there's no deposit.

Questions to ask before the viewing

The Polish question first, then the English. You can ask by phone or send them as a message.

1. Ile wynosi czynsz administracyjny i co w nim jest? — How much is the admin fee and what does it include?
2. Czy media są w cenie, czy płacę według zużycia? — Are utilities included, or do I pay by usage?
3. Czy umowy na prąd i gaz są na właściciela? — Are the electricity and gas contracts in the owner's name?
4. Jaka jest kaucja i od jakiej kwoty jest liczona? — How much is the deposit, and what amount is it based on?
5. Czy jest prowizja? Ile? — Is there an agency fee? How much?
6. Czy to zwykła umowa, czy najem okazjonalny? Na jak długo? — Is it a standard lease or najem okazjonalny? For how long?
7. Kiedy ostatnio zmieniał się czynsz? — When did the rent last change?

If phoning in Polish feels daunting, our script for calling a landlord in Polish gives you the order of the conversation. And if anyone asks for money before you've seen the flat, read the rental scam checklist first.

When the cost can change

Rent and other charges for using the flat, apart from the "fees independent of the owner", can't be raised more often than every 6 months (art. 9(1b), Tenants' Protection Act). Utilities move with settlements and supplier tariffs. So ask not only "how much now" but "when did it last change".

This cost breakdown is what we're building into RentalAgent, an AI assistant for finding a rental in Warsaw. It's meant to separate known costs from estimates and, when you explicitly ask it to, call landlords in Polish to get the missing figures. For now we're collecting sign-ups for early access.
