Developer Standard in Poland: What It Means and What Finishing Costs

In Poland, most new flats are handed over in stan deweloperski (developer standard): plastered walls, screed floors, windows, an entrance door and connection points for water, sewage and electricity, but no flooring, kitchen, bathroom fittings or interior doors. There is no single finishing cost per m², because the budget depends on the scope of work, the materials and who does the job, so it must be planned on top of the purchase price: the median price of a new flat in Białołęka in RCN notarial data was about 575,000 PLN (transactions registered from 2024-11-11 to 2025-12-19), and the fit-out comes after that.

What stan deweloperski means and why it is not a finished flat

Many expats come from markets where a new-build flat is sold with floors, a kitchen and a working bathroom. In Warsaw the default is different. A flat in stan deweloperski is technically complete: the installations are connected and you can carry out the odbiór techniczny (technical acceptance) and sign the final notarial deed. But you cannot live in it yet: there is no toilet, no shower, no kitchen sink and usually bare screed underfoot.

The term is not one fixed legal standard. Each developer describes what it delivers in the prospekt informacyjny (information prospectus) and in an attachment to the umowa deweloperska (developer agreement), and two developments in the same district can mean different things by the same words.

So the figure that matters is not the price per m² in the developer's price list but the total cost of a flat you can actually move into, plus the months of works during which you may still be paying rent.

What is included and what you will add yourself

Use this typical split as a checklist for a specific development, not as a promise of what every developer delivers.

Small details such as a skim coat, bathroom waterproofing or inside window sills move the final bill. The only binding description is the one attached to your agreement, so ask for it before you pay a reservation fee.

What the finishing cost depends on

There is no public register of fit-out prices comparable to RCN for flat prices, so any quote you see online is one contractor's offer, not a market benchmark. What you can control is the list of factors that drive the price.

• Scope. A basic finish (floors, paint, bathroom, interior doors) is a different project from a turnkey flat (pod klucz) with a fitted kitchen, built-in wardrobes and lighting.
• Materials. Tiles, flooring and bathroom fittings have the widest price spread, so the same layout can cost very different amounts.
• Wet rooms. A bathroom plus a separate WC adds more to the budget than a few extra square metres of living room.
• Kitchen. Made-to-measure furniture and built-in appliances cost more than modular units.
• Size of the flat. The kitchen and bathroom are almost fixed costs, so a smaller flat costs more per m² to finish. In RCN data the median new flat in Białołęka, Ursus, Bemowo, Włochy and Praga-Południe had about 44 to 48 m².
• Who does the work. Your own tradespeople, a general contractor or a ready package differ in price, guarantees and coordination effort; see how apartment fit-out packages are structured.
• Timing. Zmiany lokatorskie (tenant changes) ordered during construction, such as moving a wall or a water point, avoid demolition later, but developers set deadlines and may charge for them.

A price given only "per m²" without a list of materials says little. Compare offers on the same written specification.

Planning the full budget: purchase price plus fit-out

The table shows RCN medians for new flats (transactions registered from 2024-11-11 to 2025-12-19) and median asking prices from the NAWROCKI catalogue of developers' price lists, updated on 2026-11-10.

The catalogue lists 279 developments with 14,943 units on sale, and asking prices sit above transaction medians. NBP data for the second quarter of 2026 agree: the average asking price for new flats in Warsaw was 18,488 PLN per m², the average transaction price 16,783 PLN per m². That gap makes the price list a starting point for negotiating with a Warsaw developer.

On top of the price come the purchase costs. VAT of 8% is already included in the developer's price for usable area up to 150 m²; a parking space or storage unit sold as a separate unit is usually taxed at 23%. PCC of 2% is not charged on a purchase from a developer. The notary fee (taksa notarialna) has only a legal maximum, so it can be negotiated, and 23% VAT is added to it. Our full breakdown of buying costs and taxes in Poland covers each item. Then add finishing as a separate line, based on real quotes.

Paying for the finishing: own funds or mortgage

Finishing money is needed right after the keys are handed over, close to the last instalment to the developer, so plan cash flow for that moment.

With a typical mortgage rate of about 6% (rates as of 2026-11-01), a flat priced at 575,000 PLN with a 20% down payment of 115,000 PLN means a loan of 460,000 PLN, which over 25 years gives an equal monthly instalment of about 2,964 PLN. You can run your own numbers in the mortgage and affordability calculator.

Whether finishing can be financed by the same mortgage depends on the bank and on the valuation of the flat. Some banks accept a higher loan amount for the fit-out, others expect own funds, so ask before you sign the umowa deweloperska.

Under the Developer Act of 20 May 2021, payments to the developer go to a mieszkaniowy rachunek powierniczy (residential escrow account) and are protected by the Developer Guarantee Fund (DFG). Money paid to a finishing contractor has no such protection, so pay in stages against completed work.

Developer standard differs: what to read before you sign

Before reserving a flat, ask for the prospectus and the full standard description and check:

• Whether walls have a skim coat and the screed is ready for flooring.
• Whether the bathroom has waterproofing and where the ventilation is.
• Whether inside window sills, radiators and an intercom are included.
• How many sockets and lighting points there are and where.
• Which tenant changes are possible, until when and at what cost, and whether they affect the developer's warranty.
• Whether the developer offers its own fit-out package and on what terms.

A strong standard description is worth little if the company delays handovers or argues about defects, so verify the Polish developer before any payment.

Step by step: from reservation to moving in

1. Shortlist developments and compare the asking price per m² with RCN transaction prices in the district, for example RCN transaction prices in Białołęka.
2. Ask for the prospectus and the standard description before paying a reservation fee.
3. Decide on tenant changes early, while walls and installations can still be moved without demolition.
4. Set the finishing budget and its financing before signing the developer agreement.
5. Collect quotes from contractors on one written specification and check their contract terms and guarantees.
6. At the technical acceptance, list every defect in the protokół odbioru (acceptance report); the Developer Act sets deadlines for the developer to respond and fix them.
7. Sign the notarial deed and take the keys; start works only once the defects that affect them are fixed or documented.
8. Pay the contractor in stages and keep invoices and guarantee documents.
9. Check installations and finishes before moving in.

Mistakes that cost buyers money

The most common mistake is comparing price lists without comparing standards: a cheaper price per m² can disappear once you add what another developer includes. The second is starting finishing before the technical acceptance is closed, because once floors and tiles are laid it is harder to prove that a defect came from the developer.

Other costly errors:

• choosing a contractor by the lowest price per m² without a specification;
• paying a large advance before any work is done;
• planning sockets and lighting after the bathroom and kitchen are tiled;
• assuming that the bank will finance the fit-out without asking first.

How NAWROCKI Real Estate helps with a flat in developer standard

NAWROCKI Real Estate is a buyer's agent for new-build flats in Warsaw. We compare offers of many developers at once and check each developer's price per m² against real notarial transactions (RCN) in the district, so you see whether the price-list figure is reasonable before you budget for finishing. We read the umowa deweloperska and the information prospectus, including the description of what the developer standard covers, and point out what is missing.

We negotiate price and terms with developers, keep track of the payment schedule, and help with the technical acceptance of the flat (odbiór techniczny), so that defects are recorded before your fit-out begins. In most developments we work with, the developer pays our fee, so for the buyer the service is usually free; if not, we say so before starting.
