This rule requires each public housing agency (PHA) administering public housing to implement a smoke-free policy. Specifically, no later than 18 months from the effective date of the rule, each PHA must implement a "smoke-free" policy banning the use of prohibited tobacco products in all public housing living units, indoor common areas in public housing, and in PHA administrative office buildings. The smoke-free policy must also extend to all outdoor areas up to 25 feet from the public housing and administrative office buildings. This rule improves indoor air quality in the housing; benefits the health of public housing residents, visitors, and PHA staff; reduces the risk of catastrophic fires; and lowers overall maintenance costs.
