Amsterdam's Subletting Crackdown Is Fining the Wrong People

Amsterdam's fines for illegal subletting can reach €20,750 for repeat offenses. Rotterdam is stepping up enforcement too. The messaging from municipalities is clear: we're cracking down on housing fraud and protecting the integrity of the rental market.

But here's what actually happens. An international renter finds a room on Kamernet or a Facebook housing group. The listing looks normal — maybe a bit cheap, maybe missing some details. They sign something, pay a deposit, move in. Weeks or months later, there's a knock on the door from the municipality. The sublet is illegal. The main tenant didn't have written permission. And now the person sleeping on that mattress on the floor is the one facing fines and eviction.

The primary tenant might get fined too. But the landlord? The one who owns the property, who may have tacitly allowed this arrangement to continue, who benefits from continuous rent payments while the bureaucracy sorts itself out? Almost never.

Dutch tenancy law places the onus of compliance on the tenant. The landlord's legal obligation is essentially to ensure the property isn't being used for illegal activities — but in practice, enforcement agencies prioritize tenant violations. Landlords rarely face penalties unless they're directly involved in large-scale housing fraud or repeated violations.

This creates a perverse incentive structure. A landlord in Amsterdam or Utrecht can turn a blind eye to subletting because it guarantees continuous rent payments and avoids vacancy. Some landlords tacitly encourage it to avoid empty periods or to extract higher rents from desperate tenants. When the sublet is exposed, the landlord simply terminates the tenancy on contractual grounds and re-lets the property — often at a higher price, often to another international renter who'll be in the same precarious position six months later.

The landlord walks away clean. The main tenant loses their lease. The subtenant loses their home. Nobody upstream is held accountable.

International renters don't choose illegal sublets because they're careless. They choose them because they often don't have another option.

The barriers are stacked from day one. Language barriers mean many internationals can't read Dutch rental contracts or understand legal terminology. Discrimination in the formal rental market makes it harder for them to secure standard leases — some landlords simply prefer not to rent to people without a Dutch guarantor or a long local rental history. Limited supply and high demand mean that by the time an international renter finds anything available, they're in no position to demand written subletting permission or question whether registration is possible.

Here's the tell: if a listing says registration isn't possible, it's almost certainly an illegal sublet. But if you've just arrived from abroad, you don't have a BSN yet, you need an address, and the only person responding to your messages on Pararius is someone offering a room in their apartment — you might not know that "no registration" is a red flag. You might think it's normal. You might think it's just how things work here.

Subletting a room typically yields between €300 and €700 per month for the main tenant, with higher amounts in Amsterdam and Rotterdam. That's not nothing — but it's a fraction of what the property owner is collecting in rent. The person at the bottom of this chain is paying the most for the least security.

Dutch law does offer a theoretical lifeline. Article 7:269 of the Dutch Civil Code says that if the main tenancy ends, the subtenant may automatically become the direct tenant of the property owner — provided certain conditions are met.

In practice, almost no international subtenant can invoke this. The protection doesn't apply to room rentals or cases where the subtenant lacks a housing permit (woonvergunning). Many subtenants don't have written contracts or proof of payment. They don't know their rights. And the prospect of navigating the huurcommissie or Dutch legal proceedings in a foreign language is intimidating enough that most people just leave.

Landlords know this. They exploit procedural delays and legal loopholes to regain possession before subtenants can assert any rights. The law exists on paper, but the power dynamics make it functionally inaccessible to the people who need it most.

None of this means subletting enforcement is wrong. Unregistered subletting does distort an already squeezed housing market. But cracking down on the weakest link in the chain — while ignoring everyone upstream — isn't enforcement. It's scapegoating.

If Amsterdam and Rotterdam actually wanted to address ongeregistreerde onderhuur, they'd start with the landlords who enable it. Fine property owners who repeatedly allow unregistered subletting on their premises. Require landlords to provide written confirmation of subletting permissions to both tenants and subtenants. Mandate transparency in rental contracts — clear clauses on subletting and registration, in multiple languages, so the next international renter doesn't discover their contract is illegal when the municipality shows up.

The housing shortage is the root cause. International renters turn to subletting because they can't access affordable, formal housing — and because discrimination in the rental market narrows their options further. Until that structural problem is addressed, enforcement will keep punishing symptoms while the disease spreads.

At House Hunter, we see the fallout of this constantly. International renters come to us after losing a sublet, desperate for something legal and fast. The system that just fined them didn't offer them a legal alternative. It just told them to leave.
