Sewer lateral installations and drain connections that cross or are located within the County Right-of-Way in Los Angeles require encroachment permits. This article explains the basics of what you need to know before starting this type of project.
What Are Sewer Laterals?
A sewer lateral is the pipe that connects a private property's plumbing to the public sewer main located in the street or right-of-way. When a new sewer lateral is installed, modified, or repaired in the right-of-way section, it typically requires a permit from Los Angeles County.
When Permits Are Needed
Encroachment permits are needed for new sewer lateral connections to the public main, lateral repairs or replacements in the right-of-way, drain connections crossing County property, and any excavation in the right-of-way to access sewer or drainage infrastructure.
What the Permit Process Involves
The encroachment permit process typically involves submitting application materials showing the proposed work, identifying the connection point, providing insurance documentation, and paying applicable fees. Trench restoration requirements may also apply after work is completed.
Protecting Public Infrastructure
The permit process helps ensure sewer lateral work meets County standards and doesn't damage existing infrastructure. Properly permitted and inspected work protects both the property owner and the public sewer system from future problems.
