Efforts to restrict smoking in Boston are moving from bars and office-buildings to private homes.

Mayor Thomas Menino is scheduled to launch Boston’s first smoke-free housing registry on Tuesday. The initiative seeks to resolve a problem posed by secondhand smoke in multiunit housing, where toxic fumes can seep from one apartment to another and bother other residents.

Under program, residents of Boston’s smoke-free buildings are protected by a written no-smoking policy that prohibits smoking anywhere inside the building as well as outdoor areas where smoke may contaminate indoor air.

City officials are also set to unveil a public awareness campaign to encourage landlords to list their smoke-free properties and tenants to use it to find housing.

Officials are also expected to discuss other citywide efforts to reduce smoking. (AP)
