Declares the nationwide shortage of deeply affordable rental housing a national emergency and urges federal, state, and local governments, together with private and nonprofit partners, to expand and preserve affordable rental supply, strengthen rental assistance programs, and protect tenants. It frames the problem (rising rents, stagnant incomes, aging subsidized housing, and insufficient federal help) and calls for coordinated policy, investment, and community-based solutions rather than authorizing new spending or creating new programs.
