What is the Mieterverband (Swiss tenant association)?

The Mieterinnen- und Mieterverband (MV) is the tenants' association of Switzerland, called ASLOCA in French-speaking and ASI in Italian-speaking Switzerland. The yearly fee depends on the section (fee tables on mieterverband.ch and asloca.ch). Members get free legal advice on rental disputes, letter templates for rent challenges and notices, representation at the conciliation authority and access to specialised lawyers. With more than 230,000 members, according to the association, it is the main tenant defence organisation. It protects you once you are in a flat. aptari helps you get there: the listings of Homegate, ImmoScout24, Flatfox and about 800 cooperative websites in one feed, and a Tenant Passport you build once.

Three names, one organisation

  • Mieterinnen- und Mieterverband (MV) · German-speaking Switzerland
  • ASLOCA · French-speaking Switzerland
  • ASI (Associazione Svizzera Inquilini) · Italian-speaking Switzerland

All three are part of the same Swiss Tenant Federation but operate locally.

What membership gets you

Free legal advice

  • Phone consultation with rental lawyers
  • In-person consultations at cantonal offices
  • Email Q&A for simple questions

Letter templates

  • Rent challenge (Mietzinsanfechtung)
  • Termination notice
  • Defect notice (Mängelrüge)
  • Deposit return demand

Schlichtungsbehörde representation

  • They represent you at the conciliation hearing
  • Free for members
  • Many disputes are settled here without going to court

Specialised lawyers

  • When conciliation fails, member rate at partner law firms
  • Often cheaper than going alone

Further services and websites

  • Review of a lease before you sign
  • Legal protection insurance for disputes with the landlord, depending on the section
  • Political representation of tenants
  • Websites: mieterverband.ch (German), asloca.ch (French), asi-infoalloggio.ch (Italian)

Cost-benefit

The yearly fee is small compared with:

  • Paying a lawyer yourself for a case at the conciliation authority (Schlichtungsbehörde)
  • A successful rent reduction, which lowers your rent every month for as long as you stay
  • Avoiding a termination you could have challenged

Most Swiss tenants don't join until they have a problem. Joining BEFORE you have a dispute is recommended.

And before any of that: finding the flat

The Mieterverband protects you inside a tenancy. aptari helps you get into one: one open feed of listings from Homegate, ImmoScout24, Flatfox and cooperative websites and a Tenant Passport you fill once, so on listings from aptari partner agencies you apply with one click instead of re-sending the same dossier. One-click apply starts as soon as partner agencies list on aptari; none have yet.
