Sewer Line Permit Requirements
The on-line permit is available for properties in Sunnyvale with a residential zoning district.
Zoning district information is available on-line by clicking on E-Zoning.
This permit will allow replacement of the existing sewer line between the building and the City
clean out. Following are the minimum requirements that must be met based on the 2007 California Plumbing Code:
-
The new sewer line materials shall be cast iron, copper, vitrified clay pipe,
Schedule 40 ABS or PVC plastic pipe. (CPC 701.1)
-
The new sewer line must be buried a minimum of 12" below finish grade. (CPC 718.3)
-
A cleanout must be placed within 2 ft. of the building and another cleanout must be installed at
the property line. (CPC 707.5 and 719)
-
The sewer line must be installed with a minimum 2% slope or ΒΌ" to the foot. (CPC 708)
The Sewer Line Permit is NOT available on-line if you are:
- If it is part of a larger remodel project.
- Replacing or repairing a septic tank or system.
- Installing a new connection to the City sewer main.
|
If any of the above conditions apply, the permit shall be issued at the One-Stop
Permit Center, City Hall, 456 W Olive Avenue. Specific process information
is available at the
Building Division web site.

Inspections
- Two inspections are required for sewer line replacements, a rough and a final. The rough inspection should be scheduled when the new sewer line is installed (but before it is connected to the City connection) and filled with water to check for any leaks. The final inspection should be scheduled when all work is completed.
