OCPM “Form AL” and notifying Régie for a family member moving in

Hi everyone,

I rent an apartment in Geneva through a régie. My sibling (non-EU) has just been admitted to a university in Switzerland and will be moving in with me.

She is applying for her residence permit, and the OCPM has requested Form AL: Attestation du logeur – Entrée sous-locataire.

I also checked my rental contract and it doesn’t clearly say whether I must inform the régie in this situation.

If anyone has experience with or is familiar with this process, could you please advise

• Should I notify the régie when a family member moves in?
• For Form AL, can I sign it myself as the tenant, or does the régie/landlord need to sign?
• Any other practical considerations

Thanks in advance!
