Rental laws define permissible tenant service charges

Regulations regarding service charges and operating costs in rental agreements emphasize that tenants are only responsible for costs explicitly defined in their lease. Under German law, operating costs must be ongoing expenses related to the regular use of a building; one-time expenses for property value increases or maintenance are generally the landlord's responsibility.

Specific restrictions have been implemented in Germany, such as the cessation of passing on cable TV fees and the requirement for landlords to bear certain CO2 pricing costs. In Switzerland, legal precedents dictate that vague clauses, such as referring broadly to ‘general conditions’ or stating ‘all costs are borne by the tenant,’ are insufficient to mandate separate service charge payments.

Commonly permissible costs include water, drainage, heating, cleaning, and general electricity. Tenants often pay these via ‘Akonto’ (advance) payments, which are reconciled annually to determine if a balance is owed or if a refund is due.
