What Are Housing Costs (KdU)?
Kosten der Unterkunft und Heizung -- commonly abbreviated as KdU -- refers to the housing costs that the Jobcenter covers as part of Bürgergeld benefits. This component typically makes up the larger share of total Bürgergeld payments, especially in expensive housing markets. KdU covers two main categories: the costs of accommodation (Unterkunft), which includes base rent (Kaltmiete) and cold operating costs (kalte Nebenkosten such as water, garbage collection, building insurance, and property tax), and heating costs (Heizung), which covers the actual cost of heating the apartment, whether through gas, oil, district heating, or other energy sources.
The Jobcenter pays KdU directly to the landlord in many cases, though it can also be paid to the benefit recipient who then forwards the rent. Direct payment to the landlord is increasingly common and preferred by both Jobcenter and landlords as it ensures timely rent payment and reduces the risk of eviction due to payment difficulties.
Appropriateness Limits (Angemessenheitsgrenzen)
The central concept in KdU is Angemessenheit (appropriateness). The Jobcenter does not cover unlimited housing costs -- only those considered appropriate for your household size and local housing market. Each district or municipality sets its own limits based on local rental data, typically derived from the Mietspiegel (rent index) or a specially commissioned housing market analysis.
As a general guideline, the appropriate living space is roughly 45 to 50 square meters for a single person, 60 square meters for two people, 75 square meters for three people, and 90 square meters for four people, with approximately 15 additional square meters per additional person. However, the actual criterion is usually the total Bruttokaltmiete (base rent plus cold utilities) rather than the square footage alone. A smaller apartment at a higher price per square meter may be acceptable if the total rent stays within the limit, while a large apartment at a low price per square meter might also be approved.
The limits vary dramatically across Germany. In a small town in Thuringia, the KdU limit for a single person might be 300 EUR per month, while in Munich it could be 700 EUR or more. This reflects the enormous differences in German housing markets. You can typically find your local limits on your Jobcenter's website or by asking your case worker directly.
The Grace Period (Karenzzeit)
For the first 12 months of receiving Bürgergeld, the Karenzzeit applies. During this period, the Jobcenter covers your actual housing costs regardless of whether they exceed the local appropriateness limit. This means if you were paying 800 EUR rent when you became unemployed and the local limit is 600 EUR, the Jobcenter pays the full 800 EUR during the first year.
The Karenzzeit was one of the most significant innovations of the Bürgergeld reform. Under the old Hartz IV system, people were often pressured to move to cheaper apartments almost immediately after losing their income, causing enormous stress on top of the already difficult unemployment situation. The grace period gives people twelve months to stabilize their finances before addressing housing costs.
The grace period resets after you have been off Bürgergeld for at least six consecutive months. If you find a job, leave the benefit system, and later need to return to Bürgergeld, you receive a fresh 12-month grace period.
The Cost Reduction Procedure (Kostensenkungsverfahren)
After the Karenzzeit ends, if your rent still exceeds the local appropriateness limit, the Jobcenter initiates a formal Kostensenkungsverfahren. This process begins with a written notice (Kostensenkungsaufforderung) informing you that your housing costs exceed the limit and asking you to take steps to reduce them within six months.
The Jobcenter must specify what it considers appropriate and provide concrete information about available housing alternatives. A vague demand to 'reduce costs' without specifics is legally insufficient and can be challenged. The six-month deadline gives you time to explore your options without immediate financial pressure.
Options for reducing housing costs include negotiating a rent reduction with your landlord (providing the Jobcenter's letter often helps), taking in a subtenant to share costs (with landlord permission), or moving to a more affordable apartment (the Jobcenter covers reasonable moving costs if the move is necessary to meet KdU limits). Only after the six-month period has passed will the Jobcenter reduce the housing component to the local limit.
Heating Costs
Heating costs are covered separately from base rent and cold utilities. The Jobcenter assesses heating costs against a Heizkostengrenze (heating cost limit) based on your apartment size, the energy source, and local energy prices. The relevant reference is often the nationwide heating cost index published by the Bundesweiter Heizspiegel.
In practice, heating costs rarely cause problems unless they are extremely high due to an inefficient heating system, poor insulation, or excessive energy use. If the Jobcenter considers your heating costs unreasonably high, it will typically ask you to reduce consumption rather than immediately cutting the benefit. Only in clear cases of waste (such as heating with windows open or maintaining tropical temperatures) will the Jobcenter refuse to cover the full amount.
Example Calculation
Consider a single person living in a mid-sized city in North Rhine-Westphalia. Their monthly housing costs are: Kaltmiete 420 EUR, Nebenkosten 80 EUR, Heizkosten 70 EUR, for a total Warmmiete of 570 EUR. The local KdU limit for a single person is Bruttokaltmiete of 450 EUR plus reasonable heating of up to 80 EUR. Their Bruttokaltmiete is 500 EUR (420 + 80), which is 50 EUR above the limit of 450 EUR.
During the Karenzzeit (first year), the Jobcenter covers the full 570 EUR. After the grace period, the Jobcenter sends a cost reduction notice. If the person cannot reduce costs within six months, the housing component is reduced to 450 EUR (appropriate Bruttokaltmiete) plus 70 EUR (heating, within limits) = 520 EUR. The person must cover the remaining 50 EUR from their Regelbedarf.
What to Do If Your Rent Is Too High
If you receive a Kostensenkungsaufforderung, do not panic. First, verify that the Jobcenter's appropriateness limits are current and correctly applied -- errors are not uncommon. Second, check whether any exceptions apply to your situation. People with disabilities, the elderly, families with school-age children (to avoid school changes), and those with strong social ties to their neighborhood may have grounds for a higher limit.
If you need to move, the Jobcenter must approve the new apartment's costs before you sign the lease (Zusicherung). The Jobcenter also covers reasonable moving costs, including a security deposit (provided as a loan), professional movers if you cannot move yourself, and renovation costs for the new apartment if required by the landlord. Keep all receipts and get Jobcenter approval in advance for any expenses.
If you believe the Jobcenter's decision is wrong, you have the right to file a Widerspruch (formal objection) within one month of receiving the notice. Many Kostensenkungsaufforderungen are successfully challenged, especially when the Jobcenter's housing market data is outdated or the appropriateness concept is not properly documented.
