Does a real estate developer in Poland have to have a website? [2025 Act]

Many real estate developers still ask:
do I really need to have a website if everything is already listed on property portals?

Let’s be clear – yes, you do.
And not because “it’s good to have one.”
Starting October 11, 2025, not having your own website with specific data is a legal violation.

In this post, I show exactly what your website must include, how to automate the data upload, and why this is no longer just about marketing – it’s about compliance.

2025 Real Estate Developer Act Amendment – what changed?

It came into effect on July 11, 2025.
Developers had 2 months to implement the changes.
That period is now over – October 8, 2025, was the deadline.

From now on:

1. every real estate developer must have their own website,
2. must publish detailed property investment information on it,
3. must update the data the same day any change occurs,
4. and every advertisement or listing must include the link to that website.

What exactly must be on the website?

This is not a list of “best practices.” These are legal requirements.

You must publish, among others:

1. the general part of the property investment prospectus,
2. developer information: headquarters, contact, sales office,
3. exact location of the property investment,
4. gross prices (units, additional rooms),
5. all additional costs (e.g. parking space),
6. price change history with dates,
7. data updated on the same day the change occurs,
8. link to the website in every ad – without it, the ad violates the Act.

What if you don’t have a website or don’t update data?

Simple: it’s a breach of the law.

You risk:

1. claims from clients (e.g. demanding an earlier advertised price),
2. UOKiK intervention,
3. accusations of violating consumer rights,
4. reputational damage,
5. lack of legal compliance = problems during audits and legal disputes.

How to manage this without chaos?

Running several property investments? Prices change frequently?
Manually managing the website and documents is a recipe for failure today.

The solution?

PanelDlaDewelopera.pl – a tool that automates:

1. publishing data in compliance with the Act,
2. generating price history,
3. real-time updates,
4. sending data to the ministry – without manual clicks.

If you want peace of mind, this is one of the few tools combining automation, law, and UX.
