....nicht genau 21h00 aber 22h00 ist gut genug

====House rules & regulations ====A lease will also contain general rules which apply to you as a resident tenant. In many apartment blocks with numerous tenants, these rules are often summarized in a separate document ( Hausordnung/ règlement d’immeuble). Among other things, they can stipulate the following:

• No excessive noise between 22:00-06:00 and 13:00-14:00. Note that your Swiss neighbours will probably take this rule very seriously and will expect you to do likewise!
• No showers or baths between 22:00-06:00.
• Restrictions for children, i.e. no playing on the grass.
• A rule stating that you’re not allowed to leave your shoes in front of your door.
• Stipulations about the separation of different types of garbage.
• Rules for commonly used rooms such as the washing machine room.

Take into account these rules form part of your contract; breaking them can give your landlord the legal right to kick you out of the apartment. This can come as a bit of a shock to foreigners coming from less ‘regulated’ countries. So do not be surprised if your housewarming party causes complaints from your new (and now very angry) neighbours. A personal introduction on your move in can help here, though it’s not standard in Switzerland.
