The Sonoma County Board of Supervisors has voted to increase the county’s living wage for the first time since 2015, raising it 11.6 percent from $15 to $16.75 an hour.

Effective Jan. 1, the increase applies for all county government employees and those in private companies and nonprofits that are contracted for the county.

The pay increase will apply to all private companies with more than six employees and if they supply at least $25,000 in contract services. It will also apply to nonprofit organizations with more than 25 employees if they provide $50,000 in services.

The county’s Department of General Services estimates an additional $542,000 in costs for paying more for the following contracted services: janitorial services, fleet repairs, auto care, sanitation, strategic grazing, security and veteran building care. Other county departments have yet to estimate annual costs.

“This conversation fundamentally is about economic dignity. We are trying to invest in the kind of society that we want to live in,” said Lynda Hopkins, chair of the Board of Supervisors, in a statement. “We are united and going in the right direction.”
