Help keep your workplace informed with the 2026 San Mateo County Labor Law Poster from Best Labor Law Posters. San Mateo County has local minimum wage requirements in addition to California and federal employment laws. Effective January 1, 2026, the County minimum wage is $17.95 per hour for employees covered by the County ordinance who work in the unincorporated areas. Covered employers must post the official minimum wage notice in a location where employees can easily read it and must provide employees with written information about their rights. The County notice explains the minimum wage, annual rate adjustments, employee protections, complaint options, and protection against retaliation. Tips cannot be counted toward the County minimum wage. Employers should also understand that the County minimum wage does not apply throughout every incorporated city in San Mateo County; cities such as Belmont, Burlingame, Foster City, Half Moon Bay, Menlo Park, Redwood City, San Mateo, and others may have separate local minimum wage requirements. Best Labor Law Posters offers local city and county, California state, federal, OSHA, and digital labor law poster solutions to help businesses manage workplace posting requirements. Employers should review the requirements applicable to each individual worksite and keep all required notices current.
