Cambridge Housing Authority’s (CHA) Family and Elderly Housing Program consists of apartment complexes (also known as developments) and individual apartments in which the subsidy is property-based (attached to the apartment, and not mobile (attached to the tenant). Within the Family and Elderly Housing Program, there are different types of sub-programs, with slightly different rules, with the biggest difference being the income eligibility requirement for admission into the respective programs. In order to be admitted into a particular program, the applicant household must not exceed the maximum income limit for that housing program.
