WGs and Subletting (Zwischenmiete): Shared Living in Munich
How shared living works in Munich: joining a WG, the Hauptmieter vs Untermieter setup, why subletting needs landlord permission, and how Zwischenmiete works.
Key Takeaways
- A WG room is the fastest, cheapest route to a Munich address and is usually furnished with bills included.
- Confirm subletting is permitted (Paragraphs 540 and 553 BGB) and know whether you are the Hauptmieter or an Untermieter.
- Insist on a written Untermietvertrag and a Wohnungsgeberbestätigung before paying, so you can complete your Anmeldung.
For many newcomers the quickest and cheapest way into Munich is not a flat of your own but a room in a shared one — a WG-Zimmer (a room in a Wohngemeinschaft, or flatshare). It costs a fraction of a solo apartment, often comes furnished, and can get you a Munich address in weeks rather than months. But shared living has its own rules, especially around who is legally on the lease, and getting those right protects both your money and your right to register. Here is what to know.
Why a WG works for newcomers
A room rents for far less than a whole flat, the search moves faster, and you arrive into a ready-made social circle — all valuable when you are new in town. Most WG rooms are advertised on WG-Gesucht, covered in our portals guide. Many are furnished and bills-included, which removes a lot of setup hassle in your first months.
Hauptmieter versus Untermieter
The key question in any WG is who holds the head lease. The Hauptmieter (main tenant) signs the contract with the landlord; everyone else is usually an Untermieter (subtenant) whose contract — the Untermietvertrag — is with the main tenant, not the owner. That distinction decides who you pay, who returns your deposit, and what happens if the head tenant moves out, so always know which role you are taking.
Subletting needs the landlord's permission
Under German law (Paragraphs 540 and 553 of the BGB), a main tenant generally needs the landlord's consent to sublet. A properly run WG has that permission; an informal arrangement that does not can leave your tenancy on shaky ground. Ask directly whether subletting is approved, and be wary of any room where the answer is vague — your security depends on it.
How Zwischenmiete works
A Zwischenmiete (interim sublet) is a temporary let, classically when the main tenant goes abroad for a semester or a work stint and rents their room out for a fixed period. It is ideal for newcomers needing a soft landing, but confirm three things in writing: the exact end date, how the deposit is held and returned, and — crucially — whether you can register your address there.
Register and protect yourself
To complete your Anmeldung (address registration), you need a Wohnungsgeberbestätigung (the landlord's or main tenant's written confirmation that you live there). Insist on a written Untermietvertrag and that confirmation before you pay anything, and clarify how the shared running costs, the Nebenkosten from our listing guide, are split among flatmates.
Expect a casting
WGs usually choose new flatmates by meeting them — a friendly interview often called a "casting" — rather than purely on paperwork. Be personable, honest about your habits, and treat it as getting to know future housemates, because in a WG the fit between people matters as much as the documents.
Money, deposits and moving on
In a WG the financial details are worth nailing down up front. Establish exactly how rent and the Nebenkosten are divided — sometimes equally per person, sometimes weighted by room size — and whether you pay the main tenant, who then settles with the landlord. Your deposit usually goes to the Hauptmieter rather than the owner, so get a written receipt and keep it, because if that person disappears your money can be hard to chase. Notice periods in a sublet are often shorter and more flexible than in a standard lease, especially for furnished rooms, which cuts both ways: easy to leave, but also easier to be asked to leave. Finally, ask what happens when the main tenant moves out — sometimes a subtenant can take over the head lease (a Mietübernahme) with the landlord's agreement, turning a temporary room into a permanent home, and it is worth knowing whether that door is open before you move in.
Shared living is one of the most forgiving ways to start your Munich life: cheaper, faster, and social. Just treat the legal side seriously — confirm the sublet is permitted, get a written contract and a registration confirmation, and agree how bills are shared — and a WG room becomes a genuinely smart first base while you decide where in the city you really want to be.
