Nebenkosten in Germany: What Your Rent Does and Does Not Include

In German rental language, Nebenkosten are the extra recurring housing costs that sit alongside the base rent. The legal term you will often see in the law and in formal statements is Betriebskosten.

The important point is not to memorize every possible cost. It is to understand which costs your contract says you pay, whether you pay a flat amount or advances, and whether you later receive an annual statement.

Quick answer

Under § 556 BGB, landlord and tenant can agree that the tenant bears operating costs. These are recurring costs connected with ownership or the normal use of the building, facilities and property. The Betriebskostenverordnung defines the categories in more detail.

Administration costs and maintenance/repair costs are not Betriebskosten under § 1 BetrKV.

If the contract uses Vorauszahlungen for operating costs, the landlord must generally account for them annually. The statement must normally reach the tenant no later than twelve months after the end of the accounting period. The tenant generally has twelve months after receiving the statement to raise objections, and can request access to the supporting documents.

1. Start with the base rent

The Nettokaltmiete or Kaltmiete is the base rent for the home itself.

Your contract may then add operating costs, heating and other agreed items. Berlin’s newcomer guidance uses common terms such as Nettokaltmiete, Bruttokaltmiete and Bruttowarmmiete to explain how different rent totals are built. The exact contract wording matters.

Do not use “Warmmiete” as shorthand for “everything in my life is included.” Household electricity, internet and mobile service are commonly separate contracts. Our electricity guide covers that separately.

2. What can count as Betriebskosten?

The Betriebskostenverordnung lists recurring categories that can count as operating costs. Examples include:

• property tax
• water supply and drainage
• heating and hot-water operating costs
• lift operation
• street cleaning and waste disposal
• building cleaning and pest control
• garden maintenance
• lighting of shared areas
• chimney sweeping where applicable
• certain building insurance costs
• caretaker costs to the extent they are operating costs
• certain shared facilities

This is not a menu from which a landlord can automatically charge every tenant every item. The tenancy agreement and the legal rules still determine what can be passed on in the specific case.

3. What is not Betriebskosten?

Two exclusions are especially useful to know.

Under § 1(2) BetrKV, administration costs are not Betriebskosten.

The same provision excludes maintenance and repair costs needed to remedy wear, ageing, weather damage or defects.

That means “the building needed a repair” is not the same thing as “this is a normal recurring operating cost.”

If an annual statement contains a position you do not understand, ask what the cost is and how it was allocated rather than assuming every building expense belongs in Nebenkosten.

4. Vorauszahlung and Pauschale are different

A Vorauszahlung is an advance payment. You pay an estimated amount each month, and later the landlord compares those advances with the actual allocable costs.

A Pauschale is a flat amount. The handling is different because it is not simply an advance that is later balanced in the same way.

§ 556 BGB allows operating costs to be agreed as a flat amount or as advance payments. Advance payments must be set at an appropriate level.

Berlin’s official tenant guidance explains that when cold operating costs are agreed as a flat amount, there is no normal annual settlement of those flat costs.

So when you read your rental contract, find the exact word: Vorauszahlung or Pauschale.

5. How the annual Nebenkostenabrechnung works

If you paid Betriebskostenvorauszahlungen, you normally receive a yearly Betriebskostenabrechnung / Nebenkostenabrechnung.

At a basic level, the statement should let you understand:

1. the accounting period
2. the total cost categories
3. how those costs were allocated
4. your share
5. the advance payments you already made
6. whether there is a Nachzahlung or Guthaben

Under § 556(3) BGB, the landlord must normally send the statement within twelve months after the end of the accounting period. A later additional claim is generally excluded if the landlord is responsible for the delay.

6. You also have a deadline for objections

The twelve-month period works in both directions.

Under § 556(3) BGB, tenants generally have twelve months after receiving the statement to raise objections. After that, objections can be excluded unless the late objection was not the tenant’s fault.

Do not leave a statement unopened because the amount looks small. If you want to question it, note the date you received it.

7. You can ask to see the supporting documents

§ 556(4) BGB gives the tenant the right, on request, to inspect the documents on which the operating-cost statement is based. The landlord may also provide the documents electronically.

Useful phrase: „Ich möchte die Belege zur Betriebskostenabrechnung einsehen.“

This does not mean every disagreement is automatically a billing error. It means you can ask to see the basis of the calculation.

8. Heating and hot water have special allocation rules

Heating and hot-water costs are not simply divided however the landlord prefers.

Under the Heizkostenverordnung, in standard central-heating situations at least 50% and at most 70% of heating costs are generally allocated according to measured consumption, with the remaining share allocated using area or another permitted basis. Similar 50–70% consumption rules apply to central hot-water costs.

There are exceptions and special building situations, so do not use the 50–70 rule to judge a complicated statement without checking the details.

9. Berlin comparison values are orientation, not a legal limit

Berlin publishes a Berliner Betriebskostenübersicht to make operating costs more transparent. The 2026 overview is based on 2024 operating-cost statements and explicitly says the figures are for orientation and are not legally binding.

This is useful context if you live in Berlin, but a city average does not prove that your own bill is right or wrong.

Common mistakes to avoid

• Assuming every “extra” cost is legally a Betriebskosten item.
• Confusing a Pauschale with a Vorauszahlung.
• Treating repairs or administration as normal operating costs without checking the legal category.
• Missing the date when an annual statement arrived.
• Ignoring the allocation key or your advance payments.
• Assuming your own household electricity is automatically part of Nebenkosten.

Frequently asked questions

Are Nebenkosten and Betriebskosten the same thing?

In everyday rental language, the words are often used closely together. The legal rules use Betriebskosten for recurring operating costs defined in § 556 BGB and the Betriebskostenverordnung. Always check the wording of your own contract.

Are repairs part of Nebenkosten?

Maintenance and repair costs are not Betriebskosten under § 1(2) BetrKV. A specific invoice can still require detailed review if different types of work are mixed together.

What is the difference between a Vorauszahlung and a Pauschale?

A Vorauszahlung is an advance that is later compared with actual allocable costs through an annual statement. A Pauschale is a flat amount and is not handled in the same way.

How long do I have to object to a Nebenkostenabrechnung?

Under § 556(3) BGB, tenants generally have twelve months after receiving the statement to notify the landlord of objections, subject to exceptions when a late objection was not the tenant’s fault.

Can I ask to see invoices or other supporting documents?

Yes. § 556(4) BGB gives tenants a right, on request, to inspect the documents underlying the statement; the landlord may provide them electronically.

Are heating costs always split 50/50?

No. In standard cases covered by the Heizkostenverordnung, between 50% and 70% of central heating and hot-water costs are generally allocated by measured consumption, with the remaining share allocated on an allowed basis such as area. Exceptions exist.
