Any work within a public right-of-way in unincorporated LA County requires an encroachment permit from the Department of Public Works. This includes utility connections, driveways, sidewalk modifications, and temporary construction activities.
LA County Department of Public Works requires encroachment permits for all work within public rights-of-way in unincorporated areas. This includes driveway construction or modification, utility connections (water, sewer, gas, electric), sidewalk repair or replacement, installation of signs or structures, temporary road closures for construction, scaffolding over sidewalks, and any excavation in the public way. Applications are submitted to the Public Works Permit Counter. Permits require a site plan, traffic control plan for road work, proof of insurance, and applicable fees based on the type and scope of work. All work must comply with County road standards and be inspected by Public Works before final approval. Bonds may be required for major encroachments to ensure proper restoration of public improvements.
Work without an encroachment permit: stop-work order and fines starting at $250. Damage to public improvements without a permit may result in repair costs charged to the responsible party plus penalties.
