Make workplace posting compliance easier with the 2026 San Mateo County Labor Law Poster. This local labor law poster includes the San Mateo County minimum wage notice reflecting the $17.95 hourly minimum wage effective January 1, 2026. The County requirement applies to covered work performed in unincorporated San Mateo County, including work by full-time, part-time, temporary, and seasonal employees. Employers must display the notice where employees can easily see and read it. Because cities within San Mateo County may have their own minimum wage requirements, businesses should confirm the location-specific rules that apply to each workplace and maintain all required California and federal labor law posters as well.
