Transportation Permits

Transportation Permits Section is responsible for issuing permits for work within the County Maintain Roadway System (CMRS). Any work within CMRS requires a permit from Transportation Permits Section.  

A map of CMRS can be found here, which identifies if a specific road is maintained by the County or a different agency. Roads highlighted in yellow indicate County maintained roads.

Permtis Frequently Asked Questions (FAQ)

Permit review times vary by permit type. Moving permits are typically issued within 1-3 days. All others have a typical review period of 1-3 weeks. 

Please refer to the permit Fee Schedule for permit fees.

Any work within County Maintained Road System requires a permit.

While the work or project may be located within the County, Public Works only requires a permit for work within the unincorporated area of San Bernardino County. Please refer to the linked map to determine if the work is within the unincorporated part of the County, or maintained by a neighboring agency. 

In most cases, a permit from Public Works is not required. Work within private property may require a permit from Land Use Services. A permit from Public Works may be required if work encroaches public right-of-way, such as the installation of a sidewalk, curb/gutter, or an installation or modification of a driveway or carport.

Work that breaks ground and requires digging of any kind to form an excavation, trench, well, or hole requires an excavation permit.

If work required removal and replacement of existing pole, an encroachment permit will be needed. If the work requires the installation of a new pole, an excavation permit will be required.
