The West Hollywood City Council approved an ordinance Monday night to ban plastic bags at store checkouts, the latest in a series of California cities to do so.
The law prohibits grocery and other retail stores from distributing plastic bags, the Los Angeles Times says.
Larger retailers must stop using plastic bags within six months. Smaller stores have a year to comply, while farmers markets and restaurants are excluded.
The ban is intended to reduce landfill waste and to encourage residents to shop with reusable bags or paper bags made with recycled materials.
Unincorporated areas of Los Angeles County and other California cities, including San Francisco, Los Angeles, Santa Monica, Long Beach and Pasadena, already have plastic bag bans.
