Encroachment Permits

Work in or over the public right-of-way usually requires an encroachment permit from the City of San Mateo Engineering/Permits office. Construction, excavation, utility work, sidewalks, and temporary lane closures commonly need permits. See the city's encroachment permit page for application steps and requirements. Encroachment permits[2]

  • When required: any work that occupies or alters the public right-of-way.
  • Typical conditions: traffic control plans, bonds, restoration of pavement, insurance.
  • Fees and deposits: fee schedules and bond amounts are provided by the Engineering division or noted on permit forms; specific amounts are not specified on the cited page.

Applications & Forms

The city publishes an encroachment permit application and submittal checklist on the Engineering/Permits page. If fees or form numbers are not listed there, contact Engineering for the current fee schedule and submittal instructions.

Apply early and include traffic control plans to avoid delays.

Emissions & Air Quality

Local emissions enforcement for stationary and mobile sources in the Bay Area is carried out by the Bay Area Air Quality Management District (BAAQMD); the City of San Mateo refers larger or regulated emissions matters to BAAQMD. For nuisance odors, construction dust control, and vehicle idling complaints, local Public Works and Code Enforcement coordinate with regional agencies. See the regional enforcement overview.

  • Typical triggers: visible smoke, dust from construction, excessive idling, and regulated industrial emissions.
  • How to complain: contact city Code Enforcement or file a report with BAAQMD for regulated sources.
