The Montgomery County Council voted unanimously to raise its minimum wage to $15 an hour over a period of years.
Council members voted Tuesday on an amended bill that would force large employers to adopt the $15 hourly wage by 2022.
Small employers would need to pay the higher wage by 2024.
The county raised the minimum wage in 2013 by phasing it in over several years. It has incrementally risen to $11.50 an hour, where it is currently set.
