The Massachusetts Fair Housing Law (M.G.L. c. 151B) prohibits discrimination in housing based on race, color, religion, sex, sexual orientation, gender identity, national origin, age, ancestry, veteran status, familial status, disability, or receipt of public assistance. Asking about a tenant’s place of birth could reveal information about national origin or ancestry, which are protected classes under both state and federal fair housing law.

By contrast, landlords and brokers are legally permitted to verify income and occupation to determine financial qualifications, and Massachusetts law also permits certain criminal history checks in compliance with state and federal guidelines. However, questioning applicants about their place of birth is directly discriminatory and unlawful.
