Berlin short-term rental rules (ops stub)

Ban-unless-permitted: living space in Berlin may only be used for non-housing purposes (including short lets) with a district Zweckentfremdung permit — or a qualifying notification track for a limited Hauptwohnung share.

Nebenwohnung (second home): as a furnished vacation rental / guest lodging, generally at most 90 days per year, and only with a permit. If the applicant also has a Hauptwohnung or another Nebenwohnung in Berlin, a permit “shall not be granted” (per Senate guidance).

Hauptwohnung (main home): may be let during the occupant’s absence with a permit, provided the dwelling’s character as Hauptwohnung is not impaired. No separate numeric night cap is stated on the Service Berlin page for this track.

≤49% of Hauptwohnung floor area: no permit; prior Anzeige (notification) still required to receive a Registriernummer. Above 49%: permit required.

Registriernummer (live ops note): the 4th ZwVbG update implementing the EU short-let regulation entered into force 17 Jun 2026, but technical rollout is still in a test phase — no new registration numbers are being issued. Existing numbers remain usable on platforms for now. Federal SDEP: platforms to transmit activity data from 1 Sep 2026 (retroactive for Jul–Aug 2026).
