Property due diligence in Poland: what buyers and sellers check in 2026

Poland commercial property due diligence has two structural issues that are unlike any other EU market: perpetual usufruct (użytkowanie wieczyste) affects a significant portion of Warsaw and major-city commercial land plots, and the Warsaw Decree (Dekret Bieruta, 1945) creates residual title risk in the Polish capital. Get these two right first; the rest of the diligence is standard EU commercial process.

Poland transfer costs for commercial property: Property Transfer Tax (Podatek od czynności cywilnoprawnych, PCC) at 2% of the declared property value applies to VAT-exempt transactions; if the sale is subject to VAT at 23% (new commercial within 2 years of first occupation, or seller opts for VAT on older commercial with buyer agreement): PCC does not apply - this is a fundamental structuring choice in Polish CRE. VAT-registered buyers recover the 23% VAT as input; the PCC-vs-VAT decision is made before signing and affects the net acquisition cost by the full PCC amount for non-VAT-recoverable buyers.

Poland's Land and Mortgage Register (Księga wieczysta, KW): maintained by district courts (sądy rejonowe) across Poland; publicly searchable at ekw.ms.gov.pl since 2010; each property has a KW number; four sections: Section I (property description and associated rights), Section II (ownership - właściciel or użytkownik wieczysty/perpetual usufruct right holder), Section III (rights, claims and restrictions including easements), Section IV (mortgages - hipoteki). All property transfers in Poland must be executed as a notarial deed (akt notarialny) by a Polish notary (notariusz); the notary submits the deed electronically for KW registration; registration takes weeks to months depending on court district workload.

Set up a real-estate data room before advisors engage. Load KW extracts, perpetual usufruct agreement and conversion status, building permit, occupancy certificate, MPZP zoning extract, and lease files.

Where Poland property deals actually go wrong

Not every check carries the same weight. The table below sorts them by deal impact - dealbreakers first, then what moves the price, then basic hygiene - so your Polish attorney and advisor know what to clear first.

Poland commercial property due diligence checklist

The table ranked risks by severity. This is the full checklist to work through, grouped by area.

KW Land Register search and title chain

• Day one: search ekw.ms.gov.pl for all KW numbers associated with the property; identify all cadastral parcels and KW numbers; request certified full extracts (pełny odpis KW) from the relevant district court for each KW number - online searches give current status but certified court extracts are the diligence standard
• Section II review: confirm the registered owner (właściciel) or perpetual usufruct holder (użytkownik wieczysty) matches the seller; for company sellers: exact legal name and KRS number match; note the basis of acquisition (how the current owner acquired the property)
• Section III review: list all encumbrances (obciążenia) - easements (służebności), registered claims (roszczenia), pre-emptive rights (prawa pierwokupu), injunctions (zakazy); any enforcement injunction (zakaz zbywania) registered in Section III prohibits transfer; any KW wzmianka (pending registration flag) requires full investigation
• Section IV review: list all mortgages (hipoteki) by amount, creditor, and priority; confirm the plan for discharge at or before closing; check the National Enforcement Register (KRZ at krz.ms.gov.pl) for enforcement proceedings against the seller entity

Give each advisor a scoped link in Ellty. Polish attorney sees KW extracts and perpetual usufruct agreement. Building inspector sees building permit and occupancy certificate. Environmental consultant sees GIOŚ records and Phase I ESA. Lender sees KW extract, valuation, and lease pack. Each party sees only their files.

Perpetual usufruct analysis

• Identify from Section II of the KW whether the property is held as full ownership (własność) or perpetual usufruct (użytkowanie wieczyste, UW); if UW: request the full perpetual usufruct agreement (umowa ustanowienia użytkowania wieczystego) from the seller; this agreement specifies: the term (typically 99 years from the original grant date with renewal rights), the annual fee (opłata roczna, typically 0.3% or 1% or 3% of assessed land value depending on use category), and the permitted use conditions
• Confirm the UW permitted use matches the current commercial use; the city or state can terminate a UW right if the permitted use conditions are materially breached; Warsaw has been active in reviewing UW permitted use compliance for high-value city center plots
• Confirm the annual fee (opłata roczna) is current with no arrears; the land owner (city/state) can initiate UW termination proceedings for fee non-payment; also model future opłata roczna levels - Polish municipalities update assessed land values periodically and the opłata roczna increases proportionally; Warsaw's annual opłata roczna updates have been significant for commercial plots in the city center
• Assess UW conversion to full ownership: conversion is available for commercial UW under Polish law (Act on Converting Perpetual Usufruct of Developed Land to Ownership); a conversion fee is payable (typically 20x the current annual opłata roczna for commercial); for UW near expiry or with significant opłata roczna exposure: model the conversion cost and consider negotiating it into the deal price

Load all files into Ellty. Polish attorney sees perpetual usufruct agreement, annual fee payment history, and conversion analysis. Lender sees UW term remaining and annual fee level. Track document reviews - perpetual usufruct analysis is where Warsaw deal questions concentrate.

Warsaw Decree check

• For any commercial property in Warsaw: check whether the land was privately owned before the 1939 Warsaw boundary limits; the Bieruta Decree nationalized all Warsaw land in 1945; confirm from the KW and prior ownership history whether the land was covered by the Decree and whether the former owners received the UW right they were entitled to (or were improperly denied it)
• Search Warsaw's administrative system (Biuro Mienia Miasta, successor to BASiO) for pending Decree-basis administrative proceedings on the parcel; some Warsaw parcels have pending claims filed by heirs of pre-war owners that are in administrative review or court litigation; these do not always appear in the KW Section III until a court decision is made
• The 2016 Reprivatization Act (ustawa reprywatyzacyjna, officially: ustawa o szczególnych zasadach usuwania skutków prawnych decyzji reprywatyzacyjnych) created a process to invalidate fraudulent reprivatization decisions but the Warsaw Decree issue extends beyond fraudulent cases; legitimate historical claims can still exist for parcels where the pre-war owner or heirs were improperly denied their UW right and never received compensation
• Engage a Polish attorney experienced in Warsaw Decree risk for any Warsaw commercial acquisition on historically private land; title insurance specifically covering Warsaw Decree risk has become available from certain insurers as the market has matured

Compare Czech Republic's commercial property due diligence process for Central European portfolio strategy. Poland and Czech Republic are the two largest Central European commercial markets and both EU members; key differences: Poland (PLN, one of Europe's largest logistics markets, perpetual usufruct, Warsaw Decree risk, PCC/VAT structuring) vs. Czech Republic (CZK, Prague-dominated office and retail, no RETT since 2020, church restitution risk for some assets, generally cleaner title structure); annual investment volumes: Poland typically EUR 4-6 billion vs. Czech Republic EUR 1.5-2.5 billion.

How due diligence works in Poland

Step 1 - KW search and perpetual usufruct analysis

Day one: pull KW extracts for all KW numbers from ekw.ms.gov.pl and district court. Section II: confirm owner/UW holder. Section III: map all encumbrances. Section IV: list all mortgages. KRZ: check enforcement proceedings against seller.

For Warsaw commercial on historically private land: commission Warsaw Decree search with Polish counsel immediately.

Step 2 - Building permits, MPZP, and environmental

Request building permit and occupancy certificate from seller. Verify with PINB building authority. Obtain MPZP planning certificate from municipality. For Upper Silesia or brownfield logistics: commission Phase I ESA with GIOŚ contaminated sites search.

For perpetual usufruct: request full UW agreement and current opłata roczna confirmation.

Step 3 - VAT/PCC structuring, leases, and AML

Confirm VAT/PCC treatment with Polish tax counsel before drafting the purchase agreement (the VAT election must be in place before signing). Abstract all commercial leases. Check lease registration status in KW Section III for leases over 10 years. Confirm tenant deposit instruments. Check CRBR for UBO. Confirm seller at KRS. Run OFAC and EU sanctions screens.

Step 4 - Notarial deed and KW registration

All commercial property transfers require a notarial deed (akt notarialny) executed before a Polish notary; the notary collects PCC (if applicable) and submits the deed electronically to the relevant KW court for registration; title becomes fully effective against third parties on KW registration; registration timelines vary from a few weeks to several months depending on the court district; a booking (wniosek) entered at submission creates a pending entry that protects buyer position during the registration gap.

Load closing documents into Ellty before the notarial appointment. Polish attorney sees signed akt notarialny and KW registration submission confirmation. Lender sees post-closing KW extract with buyer registered in Section II.

What makes Poland different

Perpetual usufruct (użytkowanie wieczyste) is the defining structural issue in Polish commercial real estate due diligence. It has no direct equivalent in most Western European legal systems and surprises buyers who haven't encountered it before. The concept originates from a solution to post-WWII urban reconstruction: rather than return land to private ownership immediately after nationalization, Polish law created a long-term right for private parties to use state or municipal land for 99-year terms (renewable) in exchange for an annual fee. For commercial property in Warsaw's central business district and other major Polish city centers where state or municipal land ownership is concentrated, the majority of commercial land plots are held under perpetual usufruct rather than full ownership. The practical consequences for due diligence are multiple: the permitted use condition in the UW agreement may differ from the actual current use and must be matched; the annual fee (opłata roczna) creates an ongoing cost obligation that should be checked for arrears and modeled for future increases (as municipalities update assessed land values and the fee scales accordingly); the UW right can in theory be terminated for breach of permitted use conditions, giving the land-owning municipality significant leverage; and the remaining UW term matters for leasehold financing since lenders require the UW term to substantially outlast the loan term and any primary lease term. The option to convert UW to full ownership (uwłaszczenie) has been available for residential since 2019 (automatic conversion at nominal cost) and for commercial by application with a conversion fee; the commercial conversion process is not automatic and requires negotiation with the relevant public entity. Institutional buyers have increasingly factored conversion into acquisition structures to eliminate UW uncertainty.

Poland's logistics and industrial commercial market has been one of Europe's most active since 2015, driven by e-commerce growth and nearshoring decisions by multinational manufacturers seeking supply chain proximity to European end-markets. Poland offers a combination of significantly lower labor costs than Western Europe, EU membership with integrated trade access, excellent highway infrastructure (motorway network largely completed in the 2010s), and large modern speculative logistics park development (with developers including Prologis, Panattoni, GLP, MLP, Hillwood operating in the market). The result for due diligence is that Poland's logistics CRE is relatively new stock (most modern warehouses built 2005-2024), with generally clean building permits and occupancy certificates, low environmental contamination risk for greenfield parks, and institutional-quality leases. However, brownfield logistics redevelopments in Upper Silesia and other former industrial zones introduce contamination risk, and the scale of speculative development has occasionally outpaced leasing demand in specific submarkets, creating tenant incentive structures (rent-free periods, fit-out contributions) that need to be carefully abstracted from lease agreements - headline rent and effective rent can differ significantly in post-2022 speculative logistics.

Warsaw's commercial property market is Central and Eastern Europe's largest and most actively institutionally traded market, but the combination of perpetual usufruct dominance in the center and Warsaw Decree title complexity creates a diligence burden that exceeds what a buyer of comparable assets in Prague, Vienna, or Berlin faces. The Warsaw Decree issue has been slowly resolving over 35 years of legal proceedings and administrative processes, but individual Warsaw commercial properties can still carry historical uncertainty about whether pre-war private owners' successors have fully waived or resolved their Decree-basis claims. Polish attorney firms with dedicated Warsaw Decree practice groups have developed specific methodologies for title searches that go beyond the KW extract to check Warsaw administrative records, court proceedings, and historical ownership documentation. For any Warsaw commercial in the central and inner city zones that were privately owned pre-1939: Warsaw Decree review by a specialized Polish attorney is not optional - it is a standard diligence step that should be commissioned before any deposit is paid.

Timeline and cost in Poland

Poland total buyer-side transaction costs: PCC at 2% of declared property value (VAT-exempt transactions) or VAT at 23% (new or seller-elected, recoverable for VAT buyers); notary fees (regulated fee schedule, typically 0.5-1% of transaction value for commercial); KW registration court fee (relatively modest); Polish attorney fees (0.5-1.5% of transaction value). Total effective buyer cost: 2.5-5% of transaction value for VAT-exempt PCC deals; potentially lower net cost for VAT-elected transactions where buyer recovers VAT.
