Utilities and Infrastructure California 3 Minutes Read ยท published February 20, 2026 Flag of California

In Ontario, California, contractors working in the public right-of-way or on municipal infrastructure must meet city and state licensing, permitting, and restoration requirements before beginning work. This guide explains typical steps for contractors, the city departments that enforce rules, permit and bond expectations, inspection and close-out processes, and practical actions to avoid enforcement or delays.

Scope and Who Must Comply

Contractors performing excavation, paving, utility work, sidewalk or driveway repairs, or any work that affects city streets, sidewalks, medians, parkways, drainage, or other municipal infrastructure must obtain the applicable permits and meet restoration bond or surety requirements. State contractor licensure is required where applicable; the city also requires local permits and business registration.

Permits, Bonds and Typical Requirements

Before starting work in the public right-of-way contractors generally must obtain an encroachment or right-of-way permit and submit evidence of insurance and a restoration or performance bond when the work could affect city property. Bond amounts, durations, and accepted surety types are controlled by the permitting conditions set by the city public works or engineering division. Specific bond amounts and timelines are not specified on the cited municipal code landing page; see the municipal code and public works permit pages for the controlling requirements[1].

Obtain all permits before mobilizing to avoid stop-work orders.

Common permit types

  • Encroachment/right-of-way permit for work in streets and sidewalks
  • Grading or excavation permits when earthwork is required
  • Utility permits for water, sewer, gas, or communications connections
  • Restoration or performance bonds and fee deposits as required by permit conditions

Penalties & Enforcement

The City of Ontario enforces compliance through its Public Works/Engineering, Building & Safety, and Code Enforcement divisions. Specific fine amounts and per-day penalties for violations are not specified on the cited municipal code landing page; consult the cited official pages for fee schedules and penalty tables where published[1].
