The tenant has moved out prematurely without notice, and I can't reach them — they haven't shown up for anything. What do I do when they don't respond and don't attend the move-out inspection?

Since you rent out more than one residential apartment, you must inspect the apartment no later than 2 weeks after you become aware that the move-out has taken place, according to § 187, subsection 3, and notify the departing tenant in writing with at least 1 week's notice.

It is important that the notification can actually be documented as written and sent in good time — SMS alone can be difficult to document if you have been blocked, so make sure that the email (which you have already sent) is the main evidence, and possibly keep a receipt for sending.

If the tenant does not show up, you can conduct the inspection alone. According to § 187, subsection 4, you must prepare a move-out report, which is either delivered at the inspection or sent to the tenant no later than 2 weeks after the inspection if the tenant was not present or refuses to acknowledge receipt.

Be aware of § 187, subsection 5: If you do not comply with the deadlines in subsections 3 and 4 (2 weeks for the inspection, timely written notification, timely move-out report), your right to demand repairs lapses. So it is in your own interest to have the inspection carried out and documented on time, even if the tenant does not respond.
