Housing fraud

Know what's going on behind the façade.

Is your property being illegally sublet? Are illegal activities taking place on your premises?

There is a significant housing shortage and subletting is a major problem. This means that others never get a fair chance at a property and often have to wait years until a property becomes available.

Do you suspect housing fraud? Passionate about what we do and equipped with high-quality technology, at PSG we have been solving housing fraud cases for real estate and housing corporations throughout the Netherlands for many years. PSG makes the difference!

Housing fraud

Housing fraud means all forms of unlawful occupation, unlawful reletting, unlawful use and over-occupancy of a property without the owner’s permission. It is actually a form of deception; the reality is different from what is recorded on paper or digitally.


If there is an indication of housing fraud, our specialists gather evidence that can serve as exhibits during the hearing. There are various detection methods available, and we consistently weigh up proportionality when selecting the method to use.

PSG Recherche uses the following detection methods:

  • Desk research; open and closed sources
  • Dynamic observation; tracking object/subject
  • Static observation; covert video recordings of rental or residence address.
  • Interviews; including neighbourhood investigations, witnesses, persons concerned

Video analysis software

PSG Recherche uses state-of-the-art video analysis software, which allows us to filter the images obtained for relevance using artificial intelligence, thus creating exponential value. This makes the use of a covert camera for a longer period both extremely effective, and also defensible with respect to privacy.


The report is the final product of the investigation and consists of a clear summary and substantiated conclusion. Naturally, our specialists’ findings are also part of this report and the evidence obtained will be made available to the client.

(Privacy) legislation

In order to determine whether there is housing fraud, PSG conducts targeted investigations on individuals and therefore processes personal data and material that can serve as evidence in legal proceedings. Under European privacy law, we are bound by legal obligations regarding the way in which this data is processed and the security of the data.

The main rules for the handling of personal data in the Netherlands are laid down in the General Data Protection Regulation (GDPR). PSG also acts within the applicable standards approved by the Dutch Data Protection Authority (AP) with regard to the ‘Privacy Code of Conduct sector private investigation agencies’ of the Security Sector Association of the Netherlands (NVB).
