WBS Extension: Avoid Errors for Tenants in Germany

Social Housing & Housing Entitlement Certificate 3 min read · published September 07, 2025

As a student holding a WBS, you can use state-subsidized social housing, but extending the housing entitlement certificate often has pitfalls for tenants in Germany. Deadlines are missed, documents are submitted incomplete, or changes in living circumstances are not reported. This guide clearly explains which documents are needed, how to check deadlines, which forms the responsible authorities require, and how to avoid common rejection reasons. The aim is to practically support students and tenants so that the WBS extension proceeds smoothly and housing security remains. At the end you will find concrete action steps and official contact points for quick help. I describe common mistakes when filling out applications, which extension deadlines apply and how to quickly submit missing evidence. I also list official forms and contact points so you as a tenant can respond in time.

What are common mistakes?

  • Missing deadlines (deadline): Documents are submitted too late or the municipality's deadline is not observed.
  • Incomplete evidence (document): Important proofs such as income statements or enrollment certificates are missing.
  • Not reporting changes in living situation (form): A move, household changes or study status are not reported.
  • Incorrect income calculations (rent): Monthly amounts are reported incorrectly or supporting documents are not properly compiled.
  • Not reporting a move in time (move-out): Address changes are not communicated to the responsible office.
Keep copies of all supporting documents and application papers.

Which documents do you need?

The exact list can vary by municipality. Typical documents you should submit completely and legibly include:

  • Valid ID card or registration certificate (document) as proof of identity.
  • Tenancy agreement and the completed WBS application (form), if your municipality requires a form.
  • Income statements for recent months (rent), e.g. pay slips or BAföG notices.
  • Enrollment certificate from your university for students (document) to confirm student status.
In many municipalities the enrollment certificate is mandatory for students.

How to submit documents?

Submit documents electronically via your city portal or in person at the citizens' office. Pay attention to confirmations of receipt and deadlines. Some municipalities only accept originals or certified copies; ask the office. Legal basics on housing entitlement and housing promotion are set out in housing promotion law[2], and core tenancy rules are in the BGB[1].

Respond to authority letters promptly, otherwise an application can be rejected.

Practical steps

  • Gather all required original documents and copies (document).
  • Check deadlines of the municipality and set reminders (deadline).
  • Complete forms fully and sign where required (form).
  • Keep confirmations of receipt and records for tracking (document).
  • Contact the hotline or citizens' office with questions before deadlines pass (call).
Thorough documentation increases your chances of resolving queries quickly.

Frequently Asked Questions

Students and other eligible tenants who still meet the requirements for social housing can apply for extension. Specific requirements are set by housing promotion law and local regulations.[2]
