Guide 01 · U-Permit basics

What is an Excavation U-Permit?

According to the Los Angeles Bureau of Engineering, Excavation “U” Permits are issued to public utilities and telecommunication companies regulated by the Public Utilities Commission of the State of California to install public utilities in the public right-of-way under the applicable LAMC provisions identified by BOE.

The BOE general-conditions page further states that U-Permits are issued to entities with authority to occupy the public right-of-way under a City or State Franchise Agreement, a Certificate of Public Convenience and Necessity from the State Public Utilities Commission, or other legal authority. In general, it says U-Permits are issued to utility and telecommunication companies only.

This describes a specialized permit context. It does not mean every utility project needs a U-Permit or that any person can apply.

Utility categories

Traditional/wet and telecommunication/dry utilities.

Utility

BOE examples include water, power, gas, and certain unstable substances defined by LAMC 62.00. The source includes examples of unstable substances; project classification should remain tied to the official requirements.

Telecommunication / dry

Telecommunication

BOE includes phone, video, internet, and data transmission cables, describing these as primarily low-voltage wire, cable, or fiber communications network companies.

Location matters

The public right-of-way is central to the U-Permit definition.

The official purpose statement addresses installation of public utilities in the public right-of-way. It should not be read as a general rule for work anywhere in Los Angeles.

Certain work on private property that is not in an easement dedicated to the City of Los Angeles is among the situations BOE lists where a U-Permit is not required. Work within Caltrans right-of-way is also listed as exempt from the City U-Permit context.

Location, authority, and work scope should be checked against current official requirements.

Guide 02 · Classification

U-Permit vs E-Permit

BOE describes two permit types for excavations in or under the surface of a public street or public place.

Excavation U-Permit

Public utility context

Issued to public utilities regulated by the Public Utilities Commission of the State of California.

Excavation E-Permit

Private construction and certain other contexts

Generally used for private construction such as footings, basements, building excavations, tunnels, and pipelines crossing streets, or by utility companies making infrequent installations. BOE states these permits typically require a cash or surety bond.

General orientation only. Review current BOE classification guidance rather than using this comparison as an automated permit determination.

Above Ground Facilities

AGF applications accompany related permit contexts.

BOE describes Above Ground Facility applications as utility or telecommunication applications that accompany an Excavation U or Excavation E and Revocable permits with above-ground components.

The official source says the specifications and procedures are described by LAMC 62.08, and that AGFs generally require supplemental power permits to power the facilities. It states those are permitted under the Excavation U-Permit once the AGF application is approved.

Verify the current AGF guidance

Conditional exclusions

When a U-Permit may not be required.

The official source identifies specific circumstances. Several are conditional, so the wording should not be reduced to absolute rules.

Location and work context

No substructure work
Certain private-property work outside a City easement
Work within Caltrans right-of-way
Certain pole installation, removal, and anchor situations in sidewalk areas

Other specified situations

Certain vacated streets
Potholes and soil borings under the permit contexts described by BOE
Monitoring wells, typically under an E-Permit, subject to the stated franchise circumstance
Maintenance-hole openings subject to specific ownership, representation, or licensing rules

Information should be verified against current City of Los Angeles Bureau of Engineering requirements.
