24 C.F.R. § 990.275
PBM is the provision of property-based management services that is tailored to the unique needs of each property, given the resources available to that property. These property management services include, but are not limited to, marketing, leasing, resident services, routine and preventive maintenance, lease enforcement, protective services, and other tasks associated with the day-to-day operation of rental housing at the project level. Under PBM, these property management services are arranged, coordinated, or overseen by management personnel who have been assigned responsibility for the day-to-day operation of that property and who are charged with direct oversight of operations of that property. Property management services may be arranged or provided centrally; however, in those cases in which property management services are arranged or provided centrally, the arrangement or provision of these services must be done in the best interests of the property, considering such factors as cost and responsiveness.
