SAN FRANCISCO — It may soon get even harder for smokers to light up in San Francisco.
Under legislation introduced Tuesday, people won't be allowed to smoke near the doors, vents and operable windows of any building, including restaurants, shops, offices and housing complexes.
If the ordinance is approved, smoking would be banned at farmers' markets, lines for movie theaters, concerts and sporting events, near ATMs and cab stands, and at the outdoor tables of restaurants.
Supervisor Eric Mar, chief sponsor of the legislation, says the restriction are aimed at protecting San Francisco's most vulnerable residents from secondhand smoke.
The legislation was originally proposed last year, but it ran into fierce opposition from businesses. The new proposal addresses some of their biggest concerns.
