Hello! If not all OCCUPANT AREAs are occupied how should costs for building maintenance be divided? Should they be relocated among existing occupants to cover them in full size or these costs are divided in the same ratio as RENTABLE AREA. For example, I pay 5 USD maintainance cost per square meter of RENTABLE AREA and my RENTABLE AREA is 200 square meters, thus I pay 1000 USD for maintanence cost. Some OFFICE AREAs are vacant but maintenace cost for building is fixed. Should these costs be relocated among existing tenants (for instance I will pay 1200 USD instead of 1000). Maintenance cost is separate from rent cost.
