You just landed in the Netherlands. You check your to-do-list and see the following: “Get that super important BSN number!”. You and your new housemates head down to the gemeente (city hall), lease in hand, ready to become official residents.
But then the person behind the counter gives you that look.
“Sorry,” they say, “only two of you can register at this address.”
Wait… what? It’s a three-bedroom apartment! How can that be?
Welcome to one of the most confusing rules for expats and students in the Netherlands. This rule often is a huge headache and the reason so many rental ads on sites like Renthunter say “max 2 people” or “no sharers.”
So, let’s dive in and read what it’s about.
🤯 The big misconception: there is no ‘one’ rule
Here’s the first thing you need to know: there is no single, national law that says “only X people can live in a house.”
This rule is not set by the Dutch government in The Hague. this isn’t some single, national rule from the government in The Hague. It’s actually set by your local gemeente (that’s the city council). This means the rules in Amsterdam can be totally different from the rules in Utrecht, and really different from a small village somewhere in Limburg.
The city’s biggest concern is safety and what they call overbewoning (overcrowding). They don’t want ten people living on top of each other in a tiny one-bedroom, that’s a fire hazard waiting to happen. So they set rules based on things like how many square meters the place consists of.
💡But… the gemeente’s rule is almost never the one that stops you. The real problem is usually the landlord.
🔑 The landlord’s secret: the ‘room rental permit’
Here’s the real reason you keep seeing “max 2 people” or “no house-sharers” on rental ads.
If a landlord wants to rent their property to 3 or more unrelated adults, they are officially renting out rooms (even if it’s one contract). To do this legally, they need a special, very expensive, and very hard-to-get permit called a kamerverhuurvergunning (room rental permit).
Most private landlords don’t have this permit.
Why?
- It costs a lot of money to apply for.
- The property also has to meet strict fire-safety and sound-insulation requirements.
- And on top of that, many municipalities use quota systems, once a neighborhood hits its limit, they simply stop issuing new permits.
🕵️♂️ The three sets of rules (and who cares about what)
Three different parties are involved here, and each one focuses on something different.
| Who’s Making the Rule? | Their Main Concern | What They’re Really Saying |
|---|---|---|
| The Gemeente (City Hall) | Safety & Overcrowding | “We don’t want 10 people in a tiny studio. We have safety rules based on m².” |
| The Landlord | Permits & Fines | “The gemeente will fine ME €20,000 if I don’t have a permit for 3+ sharers. So… max 2 people.” |
| The VvE (Owner’s Association) | Nuisance & Quiet | “We don’t want to turn our building into a party house. Our building rules say ‘no room rentals’.” |
As you can see, the landlord’s rule is almost always the strictest, because they have the most to lose.
👨👩👧👦 So what is the ‘magic number’?
There are two main ‘households’ in the eyes of the law:
- A Family / Couple: A family (parents and kids) or a couple in a relationship counts as one household. They can live anywhere. A landlord will never have a permit issue renting to a family of four.
- Unrelated Sharers: This is you and your friends. As soon as you are 3 or more unrelated adults, you are “room-sharing” and the landlord needs that special permit.
This is why the unofficial ‘magic number’ for most landlords is two.
Renting to two unrelated friends or colleagues is fine. It doesn’t require a special permit. But the second a third friend joins, it’s a legal and financial headache for the landlord.
