rental housing; income source discrimination.

HB 2538 prohibits Arizona landlords from discriminating against tenants based on their income source, such as government benefits (e.g., Section 8 vouchers, Social Security, veterans' benefits) or private assistance. It requires landlords to count rent vouchers or subsidies toward income requirements when evaluating tenants and bans them from refusing rentals, evicting, or charging more because of a tenant’s income source. The law also prevents landlords from advertising preferences against tenants using such assistance. Violations are treated as unlawful under existing housing laws, with enforcement by the attorney general. This directly affects renters using public assistance and landlords managing rental properties.
