Costa Mesa Street Light & Excavation Permits

Costa Mesa, California requires permits and standards for work that affects public street lighting and any excavation in the public right-of-way. This guide explains when a city encroachment or street-light permit is required, who enforces the rules, how to apply, and what penalties and appeals exist. It is written for contractors, property owners, and residents planning street-light upgrades, energy-efficiency retrofits, or trenching and utility work within city streets and sidewalks.

Overview

Most modifications to street lights, installation of new fixtures, or any excavation that disturbs pavement, sidewalks, or the public right-of-way in Costa Mesa must be permitted by the city. The Engineering or Public Works division issues encroachment permits and coordinates restoration, traffic control, and inspection requirements. For official application details and submittal requirements, see the City encroachment permit guidance and application pages Encroachment Permits^[1]. For code provisions on streets, sidewalks, and public works, consult the Costa Mesa Municipal Code Costa Mesa Municipal Code^[2].

When a Permit Is Required

• Any excavation, trenching, or backfill within the public right-of-way.
• Installation, relocation, or major modification of street lighting equipment or poles.
• Work that requires traffic control, lane closures, or sidewalk closures.
• Restoration of pavement, gutters, or landscaping after underground work.

Street-light energy-efficiency retrofits may still require notification, approved equipment lists, and an inspection to ensure compliance with safety and photometric standards. Utility-owned streetlights may also involve coordination with the utility provider; contact the city for required approvals and utility contacts Streets & Signals^[3].
