Business Hours for the Moderately Priced Dwelling Unit (MPDU) Program are 8:30 AM to 5:00 PM Monday through Friday. Drop-ins are discouraged because the MPDU program does not have on-call staff available for unplanned visits. Someone stopping by without an appointment may have to wait to see a staff member. An appointment with an MPDU staff person can be requested by calling 311, or by sending an email to email@example.com stating the issue or specific questions. If the request for an appointment is about a specific MPDU, please provide the address of the MPDU.
