Encroachment Permits - Online Applications

The City of San Mateo allows you to check the status of Encroachment Permits online from anywhere, any time, using any online-connected device. 

At the The Citizen Self-Service (CSS) Portal you can look up business tax records, track permits, planning applications, code enforcement cases, and request inspections for current permits. You no longer need to call or come into City Hall during business hours to request inspections or look up current and past records. The CSS is accessible 24 hours a day, every day of the week.
