Berlin Rental Deposit: The Four Dates That Decide When You Get It Back

You moved out in spring. The flat was empty, the keys went back, somebody said something vague about "after the Nebenkosten", and it is now September and your deposit is still sitting in a bank account with your landlord's name on it. Nobody has written to you. Nobody has taken anything off it. It is simply gone quiet.

That silence is the normal Berlin experience, and most people read it as a dead end. It is not. There are four dates hanging off the day you handed those keys back, each of them fixed by law, and each one kills a different reason your landlord has for holding on. Knowing where you are between them turns a vague wait into a letter you can write this week.

A Prussian-era apartment building on Christinenstrasse in Berlin Prenzlauer Berg, its pale ornamented facade running along the corner above ground floor shops

Christinenstraße in Prenzlauer Berg. Buildings like this one hold most of the deposits in the city, and the Berliner Mietspiegel 2026 covers around 1.6 million flats of exactly this kind.

What a Berlin rental deposit is allowed to be in the first place

Before the dates, the sum. German law caps a rental deposit at three times the monthly rent, and it says explicitly that the service-charge advances are left out of that calculation. The ceiling is three times the cold rent, and not three times what leaves your account every month.

That matters more in Berlin than people assume. The Berliner Mietspiegel 2026, published on 28 May 2026, puts the median net cold rent at 7.71 euro per square metre. On a 60 square metre flat at that median, the cold rent is 462.60 euro and the lawful deposit ceiling is 1,387.80 euro. If your contract asked for three times the warm rent, it asked for more than the law allows.

Three other things are baked into § 551 BGB and are worth knowing even years into a tenancy:

  • You were entitled to pay it in three monthly instalments. The first at the start of the tenancy, the other two with the next two rent payments. Almost nobody uses this, and almost every Berlin agent asks for the whole sum up front.

  • The money must sit separately from your landlord's own assets, at a bank, at the rate usual for savings with three months' notice. It earns interest, and the interest belongs to you. It is not a bonus at the end. It was yours the whole time.

  • Any clause that is worse for you than this is void. Not negotiable, not a grey area. Void.

There is a real lever in that second point. If you are still in the flat and you have never seen proof that the deposit sits in a separate, insolvency-proof account, you can ask for that proof, and the Federal Court of Justice has held you may hold back rent under § 273 BGB until it arrives. I would use that one carefully and in writing, but it exists.

Date one: the day the keys change hands

Everything is measured from the handover. Not from the end of the contract, and not from the day you stopped living there. The clock starts on the day the flat physically came back, which is often weeks after the notice period itself ran out.

On this day nothing is decided. Your landlord is allowed a reasonable window to look at the flat, look at the accounts and work out what they still want. Until they itemise something, the whole sum is simply under review.

Which is exactly why the handover is the only part of this you fully control. Walk the flat with them. Write the meter readings and every mark into a handover protocol. Both sign it. Photograph every room before you lock up, with the date on the file.

A signed protocol is not a legal requirement. It is just the piece of paper that decides the argument nine months later, when a claim appears for a scratch that was in the parquet when you moved in. I have seen that argument go both ways, and it always goes the way of whoever has the photograph.

A Charlottenburg Hinterhof on Knesebeckstraße. The flat stops being yours at the handover, and that is the moment the six month clock on damage claims starts running.

Date two: six months later, the damage claims die

This is the date almost nobody knows, and it is the strongest one you have.

§ 548 BGB says a landlord's claims for changes or deterioration to the flat are time-barred six months after the flat is returned. Six months, from the handover, full stop. After that date a scratched floor, a wall in the wrong colour, a hole where a shelf used to be, none of it can be taken out of your deposit, whatever the letter says when it finally arrives.

Courts also treat roughly this point as the outer edge of the normal review window. In its 2006 ruling on deposits (VIII ZR 71/05) the Federal Court of Justice said the reasonable period depends on the circumstances of the case and can run longer than six months, so it is a yardstick and not a hard stop. But it is a yardstick judges use.

So date two is where a polite question becomes a firm one. If six months have passed with no itemised deduction and no money, write once, name the date, and give a deadline about a fortnight out.

Date three: twelve months after your service-charge year ends

Here is the reason your landlord is genuinely allowed to sit on part of the money after month six.

The deposit does not only secure claims that already exist. In that same 2006 ruling the court held that it also covers a service-charge bill that has not been drawn up yet, and that the landlord may therefore keep back an appropriate part of the deposit until the settlement is due, where a back-payment is to be expected. The key word is appropriate. A reserve has to relate to what your own past statements actually came to, which is one more reason to read the Nebenkostenabrechnung line by line rather than filing it. It is not a licence to freeze the whole sum because the accounts are untidy.

And that reserve has an expiry date. § 556 (3) BGB gives the landlord twelve months after the end of the accounting period to send the statement. Most Berlin accounting periods run to 31 December, so a flat handed back in March 2026 falls in the 2026 period, which ends on 31 December 2026, which makes the statement due by 31 December 2027. Miss it, and no back-payment can be claimed from you at all, unless the delay genuinely was not the landlord's fault.

Once that window shuts, both standing reasons to hold your money are gone.

The ledger below plots all four dates from your own handover date, and lets you put in what is actually being kept back so you can see which of those claims each date removes.

A Mitte stairwell on Rosenthaler Straße. The service-charge statement that decides the last part of your deposit usually arrives through a letterbox in a hallway like this one, up to a year after you stopped living there.

Date four: your own clock, and it runs out too

The last date is not your landlord's. It is yours.

Your claim on the deposit is an ordinary claim, so it prescribes three years after the end of the year in which it fell due. A deposit that became payable in 2027 is chaseable until 31 December 2030, and then a court will not help you any more. The money is still morally yours. It is simply no longer collectable.

Berlin deposits die of drift, not of theft. Somebody moves cities, changes email, tells themselves it is only a few hundred euro and they will deal with it when the next thing calms down. Three years is a long time to think that, and it passes.

The mistake that costs the most

Every so often somebody works out a shortcut: stop paying the last two months' rent and let the deposit cover it. It feels neat. It is the single most expensive thing you can do in this whole sequence.

The deposit is security, not prepaid rent. Withholding the rent is simply rent arrears, and two months of arrears is a ground for termination without notice under § 543 (2) no. 3 BGB. You have handed your landlord a reason to end the tenancy, and you still owe the money. I would not do it for any amount.

If nothing comes back

Write first, and write with dates in it. Most Berlin landlords settle at this stage, because a letter like this makes clear you already know which claims are time-barred. Five lines is enough:

  • The handover date, and the fact that the six month limit on damage claims runs from it.

  • Which of the four dates have already passed on the day you are writing.

  • What you accept, itemised, so the argument narrows to what is actually in dispute.

  • Your bank details, so there is no procedural excuse for another month of silence.

  • A deadline, about two weeks out, written as a real date and not as "soon".

If it is ignored, a tenancy dispute has one correct address. § 29a (1) ZPO puts exclusive local jurisdiction with the court for the place where the flat is, so it is the Amtsgericht for that district and not the one near where you now live. For a typical deposit the sum is small enough that people do this themselves, and a membership at a Berlin tenants' association is worth more at this point than an afternoon of internet forums.

My move

Put the handover date in your calendar the day you hand the keys over, then put two more entries next to it: six months later, and twelve months after the end of that year's service-charge period. That is two minutes of work on the day you are already exhausted from moving, and it converts the whole thing from a feeling into two alarms.

When the first alarm goes off, write. Not angrily, just with the date in it. Most of the deposits I have watched come back came back because somebody wrote a short letter in month seven instead of waiting for a statement that was never coming.

If you are still in the flat and reading this early, the useful move is different: check what your contract actually charged you against the three-times-cold-rent ceiling, and check whether you have ever seen proof of a separate account. Both of those are easier to fix while you are still a tenant than after the keys are gone, in the same way that a rent increase letter is easier to answer in the month it lands.

None of this is advice on your own tenancy, and a contract can always have something odd in it. But the four dates are the same for everyone, and knowing where you stand between them is the difference between waiting and asking.
