Help keep your San Mateo workplace informed with the 2026 San Mateo Labor Law Poster from Best Labor Law Posters. The City of San Mateo maintains a local minimum wage requirement in addition to California and federal wage and employment laws. Effective January 1, 2026, the City minimum wage is $18.60 per hour. Covered employers generally include businesses subject to the City’s Business License Tax or employers maintaining a facility in San Mateo, and the ordinance covers employees who work two or more hours per week within the City. The requirement includes adult, minor, temporary, and part-time employees. Employers must prominently post the official notice where employees can see it, and the City also requires written notification of employee rights at the time of hire. Tips do not count toward the local hourly minimum wage. Workers are protected against retaliation for exercising their rights, and potential violations may be reported to the San Mateo County Office of Labor Standards and Enforcement. The City minimum wage is specific to the geographic boundaries of San Mateo and should not be confused with the separate minimum wage requirements that may apply elsewhere in San Mateo County. Best Labor Law Posters offers city, county, California state, federal, OSHA, and digital labor law poster solutions to help businesses manage workplace posting requirements.
