Our agency is the service provider working hand-in-glove with a landlord that is also a not-for-profit agency interested in supporting persons with disabilities in permanent, affordable housing. They maintain a large single-site building, while we provide on-site services. We routinely disclose phi to the landlord because specific units in the building are set aside for people with disabilities, and, at a minimum, the landlord needs to see that a person is eligible. Do we need a consent/authorization to release phi to the landlord? Do we need a business associate agreement?
