A standard rental agreement remains the most popular way to rent an apartment in Poland – and a document whose quality is only recognized during the first dispute. Rental law is outlined in two acts: the Civil Code (art. 659–692) and the Act on the Protection of Tenants' Rights, which acts as a protective overlay for apartments – and many "obvious" clauses found online simply cannot be effectively stipulated. This guide goes through the agreement element by element based on the full texts of both acts – from a perspective you won't find elsewhere: what to do when renting your Polish apartment while living in Chicago, London, or Oslo.
In short: a rental agreement requires four things: parties, premises, rent, and duration (art. 659 KC). For longer than one year – in writing, otherwise it acts as indefinite (art. 660 KC). Security deposit: a maximum of 12 times the rent, returned within a month of vacating the premises (art. 6 uopl). Rent increase: only with a written notice of the current rate with a 3-month notice period, no more frequently than every six months. The tenant is not responsible for normal wear and tear (art. 675 § 1 KC). Do not make photocopies of the tenant's ID – just record the data.
Four Necessary Elements – and a Form with a Trap
Art. 659 § 1 KC defines rental simply: the landlord gives the property for use for a specified or unspecified time, and the tenant pays the agreed rent. The agreement must therefore specify the parties, premises (address, possibly the land registry number), rent, and duration. The trap of form lies in art. 660 KC: a rental agreement for real estate for a period longer than one year should be in writing – without a written document, "the agreement is deemed to be concluded for an indefinite period". Thus, a two-year rental agreed upon by phone is not invalid – it is something worse: an indefinite rental with tenant protection against termination. In practice: always in writing, in two copies.
What to add beyond the minimum (everything in accordance with the law and worth its weight):
- Separation of rent from fees: rent is your compensation; utilities and independent fees should be settled according to bills or advances with settlement – art. 9 sec. 5 uopl allows the landlord to charge only independent fees not related to the owner (and only if the tenant does not have their own contracts with suppliers).
- Subletting prohibition: without this clause, the tenant can legally sublet the apartment – art. 668 § 1 KC allows for subletting or free use, "unless the agreement prohibits it." Want to maintain control (and avoid surprises with short-term rentals)? Include a requirement for written consent. Bonus: without the landlord's consent, subletting becomes a statutory ground for termination (art. 11 sec. 2 point 3 uopl).
- Indexation clause (e.g., annual based on GUS index) – because the statutory rent increase procedure is slow and formalized (below).
- Delivery and acceptance protocol as an attachment with meter readings and photos – provided for by art. 6c uopl, and without it, the presumption from art. 675 § 3 KC (the premises delivered "in good condition") resolves disputes instead of facts. We have a template and instructions in a separate guide.
- Termination rules – especially for fixed-term agreements (the entire second part is about this: Termination of the rental agreement).
Fixed or Indefinite Term?
| Fixed Term | Indefinite Term | |
|---|---|---|
| Early Termination | Only "in cases specified in the agreement" (art. 673 § 3 KC) – without a clause, both parties are bound until the end of the period | Termination with contractual or statutory notice periods (for apartments with monthly rent: 3 months to the end of the month – art. 688 KC) |
| For the Landlord | Predictability; remember that the grounds for termination from art. 11 uopl still apply | More flexibility, but tenant protection limits your actions |
| For the Tenant | Stability, but difficult to exit before the term (statutory exception: health-threatening defects – art. 682 KC) | Easy exit while observing the notice period |
| Technical Note | A rental agreement for longer than 10 years is treated as indefinite after that time (art. 661 KC) |
Security Deposit: Limits, Indexation, Return
- Limit: a maximum of 12 times the monthly rent according to the rate on the date of the agreement (art. 6 sec. 1 uopl). For occasional and institutional rentals – 6 times. Market practice usually charges 1–2 rents.
- Return: within one month of vacating the premises, after deducting the landlord's claims (art. 6 sec. 4). The deposit is subject to indexation to the current rent, but the return cannot be lower than the payment (art. 6 sec. 3).
- What can be deducted: arrears and documented damages beyond normal wear and tear – because the tenant "is not responsible for wear and tear resulting from proper use" (art. 675 § 1 KC). Worn flooring after three years is not damage; a hole in the door – yes.
- Minor repairs during the rental are the tenant's responsibility by law: painting walls, minor repairs to floors, doors, windows, and installations (art. 681 KC, art. 662 § 2). Major repairs and maintaining the premises in a usable condition – the landlord's obligation (art. 662 § 1).
Rent Increase: Slower Than You Think
You do not increase rent by email saying "from next month you pay more". The statutory procedure (art. 8a uopl): written – under penalty of nullity – notice of the current rent amount, with a notice period of 3 months to the end of the calendar month; no more frequently than every 6 months (art. 9 sec. 1b). If the increase exceeds 3% of the replacement value of the premises (the product of the area and the index published by the voivode) in a year, you must present a calculation upon written request from the tenant within 14 days – under penalty of nullity of the increase. The tenant has 2 months to challenge the increase in court or refuse to accept it (then the agreement terminates at the end of the notice). Therefore, an indexation clause in the agreement is not a whim – it is the only predictable mechanism for adjusting the rent.
Tenant Data and GDPR: Record, Do Not Copy
You can (and should) verify the tenant's identity: view their ID and record their name, surname, address, and PESEL – this data is objectively necessary for concluding the agreement and possibly pursuing claims (a lawsuit requires the defendant's PESEL number). What not to do: do not make photocopies or scans of the ID. UODO consistently penalizes the retention of identity documents without legal basis (a well-known penalty from March 2026: nearly 5.9 million PLN) and emphasizes that "copying or retaining identity documents should only be done in exceptional cases by specific and legally authorized entities" – landlords do not belong to them, and the principle of data minimization (art. 5 GDPR) works both ways. A mere photocopy is not a "replica of the document" under the Act on Public Documents (a replica must have authenticity features) – the problem is GDPR, not criminal law. Base income verification (employment certificate, bank statement) on voluntarily provided documents – for review.
Regular, Occasional, or Institutional?
| Feature | Regular Rental | Occasional | Institutional |
|---|---|---|---|
| Who Rents | Anyone | Individual not conducting rental business | Entrepreneur renting as part of business |
| Notarial Act of Tenant (submission to enforcement) | No | Yes + indication of substitute premises | Yes, without substitute premises |
| Tax Office Notification | No (you pay tax anyway) | Yes – 14 days (otherwise acts as regular) | No |
| Maximum Deposit | 12× rent | 6× | 6× |
| Recovery of Premises After Termination | Eviction lawsuit, judgment, protection period 1.11–31.03 | Request for vacating + clause for act → bailiff | Like occasional |

Tax: Only Flat Rate
Private rental is settled only with a flat rate on recorded income: 8.5% up to 100,000 PLN annual income and 12.5% on the excess (limit is shared for all your properties; spouses can declare the total under one of them after a statement). Annual declaration: PIT-28. The basis is income – you cannot deduct costs; therefore, structure independent fees (utilities paid by the tenant based on the agreement) so that they do not flow through your pocket as income. Details and traps (including settlement from abroad) – in the guide on renting inherited or gifted apartments.
Renting from Abroad? Checklist for the Expat Landlord
Proxy or Manager on Site
A standard rental agreement can be signed on your behalf by a proxy with a regular written power of attorney (art. 99 § 1 KC – rental does not require a special form under penalty of nullity). A professional rental manager typically costs around 8–15% of the monthly rent, depending on the scope (finding tenants, protocols, repairs, settlements) – for an owner across the ocean, this is usually the best money spent.
Tax Settled in Poland Regardless of Residency
Income from property located in Poland is always a Polish source – flat rate and PIT-28 also apply to non-residents. For non-residents, the appropriate tax office is designated in the province where the apartment is located (for Mazovia – Third US Warsaw-Center); how to arrange the entire tax situation while living abroad – in our guide on tax residency.
Utilities and Correspondence
Transfer utility meters to the tenant (supplier forms) or include in the agreement advance settlements based on bills; set up e-invoices and online access to community/cooperative settlements. An address for deliveries in Poland (proxy) will save you from notices waiting at the post office for 3 weeks.
Include Contact Channels in the Agreement
Record the email and phone numbers of both parties and stipulate that "technical" statements (repairs, readings) can be sent by email – but remember that terminations and increases require written form under penalty of nullity, so these must always go through the proxy or by mail.
Market Context (Otodom data, 2026): the average offered rent in the largest cities is around 3,500 PLN, in Warsaw about 3,900 PLN – with rates slightly decreasing since autumn 2025. When setting rent from abroad, base it on current offers from the same district and size, not on sentiment from years ago.
