There is no prohibition against limiting the number of occupants provided the purpose is not to discriminate on a protected basis. Under the laws of Florida, and the United States, discrimination in housing on the basis of race, religion, or gender is strictly prohibited. Furthermore, under the Americans with Disabilities Act, landlords must not discriminate against renters on the basis of any physical disability. State and federal laws prohibit landlords from discriminating against families with children. Therefore, the number of occupants allowed in a unit may not be limited if the purpose is to discriminate against a family with children. Apart from this limitation, a landlord can generally establish the number of people he or she wants to rent to. The bottom line is who is listed in the rental agreement and it is up to the landlord to enforce rental agreement.
