In May 2026, The San Mateo Main Library was certified as an Age-Friendly Business. This is part of the City of San Mateo’s commitment to becoming an Age-Friendly City. The program aims to recognize and promote San Mateo businesses and organizations that demonstrate a commitment to meeting the needs of older adults. To be certified, businesses are rated on their exterior environment, interior environment, marketing and communication, service, and other practices.

If you, or someone you know, operates a business in San Mateo and are interested in becoming certified, you can find more information at the Age-Friendly Business Certification page.
