A cleaning contract can cover a personal residence, a business office or a large facility. Whatever the case, it should clearly define what cleaning tasks are to be performed, when and how often they should be done, who will be responsible for cleaning supplies, how the cleaners will enter the facility or home and how they will be compensated. Your contract should say which individuals in the cleaning business will have access to the premises and how the parties will handle matters such as cancellations or damage to the property.
