Groningen Is the Only Dutch Student City Adding Rooms Faster Than It Loses Them — Here's Why

CBRE's twelve-city forecast is brutal: nearly 38,000 private student rooms will disappear by 2034, against roughly 16,000 built. In Amsterdam alone, the deficit nearly doubles to 11,000.

That ratio — more than two rooms lost for every one added — is the number I keep coming back to. The Dutch government has announced tens of millions of euros for new student housing, and it still won't be enough. You can pour water into a bathtub all day, but if the drain is open, the level doesn't rise.

Most cities are doing exactly that. They subsidise construction, announce plans, cut ribbons. Meanwhile the private rental stock — the rooms above shops, the shared houses in the Oud-West, the converted family homes near the station — quietly leaves the market. Landlords sell to owner-occupiers. Buildings get converted into studios that house fewer people at higher rents.

Groningen is the one city where the level is holding. Not because it's building more. Because it closed the drain.

Uitponden is the Dutch term for splitting a rental property out of the rental market and selling it as owner-occupied. A landlord with a student house in Groningen can, in principle, sell it unit by unit. The building stays. The rooms don't — not as rental rooms, anyway.

Since 2022, the Purchase Protection Act (Opkoopbescherming) has allowed municipalities to restrict this. Buy a property below a certain value cap and you can't rent it out for four years, except to immediate family. The point is to stop investors from buying up affordable housing and flipping it.

Groningen enforces it strictly. The city has also stopped granting permits to convert classic student houses into studios — a practice that typically means fewer residents per building and higher rents per head. Instead, permits go to new shared student houses.

That's the whole mechanism. Not glamorous. Not a subsidy. Just a rule that says: if it's rental housing, it stays rental housing.

Between 2024 and 2025, Groningen lost 695 student rooms. That sounds bad until you put it next to the Randstad. Cities like Amsterdam, Rotterdam, Utrecht and Delft have seen their student room supply shrink by 30 to 44% in just a few years.

Groningen's supply has stayed roughly stable, even grown slightly. It's the only major Dutch university city where additions are outpacing losses.

And the rents tell the same story. Student rooms in Groningen run roughly €350 to €650 a month. Amsterdam is well above €900. Utrecht sits at €700 to €950. If you're an international student comparing cities on cost alone, that gap isn't a rounding error — it's the difference between working twenty hours a week and not.

The city is building too. Zernike Campus is planned to add 1,500 homes. But that's a fraction of the total stock. The preservation is what's doing the work.

I've watched a lot of renters chase a lot of listings. The pattern is consistent: cities announce new builds, and the new builds get absorbed instantly — because the private stock is disappearing at the same time.

Groningen's approach works because it's coherent. Most Dutch municipalities have a patchwork of rules: one department encourages shared housing, another restricts it, permit requirements contradict each other. Groningen has a single priority — keep affordable student housing in the rental pool — and the rules point the same direction.

There's a political dimension too. Local and regional politicians in Groningen know the student housing issue is strategically important. They've been willing to intervene in the market in ways other cities haven't. That willingness is the prerequisite. Without it, the policy doesn't get enforced.

The flip side: Groningen is still vulnerable. Over 77% of its student housing supply is privately owned. If the sell-off resumes, the city could tip back into shortage quickly. The ban is holding the line, not winning the war.

Before you sign a lease, look at the city's uitponding stance. It's not usually in the brochure. It should be.

The cities that let landlords sell up are the ones where room supply is evaporating. That means tighter competition, higher rents, and more of the scams we hear about — deposits vanishing, viewings that turn out to be bait, landlords demanding three months upfront without a contract.

Groningen isn't paradise. It lost 695 rooms in a year. You still need a BSN, you still need to move fast, and the good listings still go in hours. But the structural trend is on your side in a way it isn't in Amsterdam or Utrecht.

If you're applying to multiple cities, this is a real factor. Not the only one — programme, campus, language, cost of living all matter. But the city's housing policy is part of your quality of life for the next three or four years.

The Dutch student housing crisis is usually framed as a construction problem. Build more. Subsidise more. Cut the waiting lists.

Groningen suggests the framing is wrong. The crisis is a preservation problem. For every room built, more than two disappear from the private market. You can't out-build that.

Other cities could adopt similar policies. The Opkoopbescherming already exists nationally. What's missing is enforcement and the political will to use it. Groningen has shown it's possible. That's the uncomfortable part — the solution isn't new money, it's a rule that some landlords won't like.

If you're hunting in a city that hasn't figured this out, plan accordingly. Move earlier than you think you need to. Have your documents ready. Watch listings obsessively, or let something watch them for you. The structural trend won't wait for you to catch up.
