Yes, all vendor equipment and leased equipment is included in this credit. That said, for multi-tenant buildings, up to 10% of the floor area may be exempted from almost any credit if the area is not under management control. If you do not control the cleaning in more than 10% of your building, you will have to work closely with your tenants in order to achieve this credit.
Question
In a multi-tenant building, some tenants have their own cleaning contractor. Does their equipment need to be included in the calculations for this credit?
