Additions can trigger a lateral video
Santa Barbara property owners are responsible for the sewer lateral from the building up to and including the tap at the city main. The Sewer Lateral Inspection Program can require a video inspection by a certified plumbing inspector after a sewage spill from the property, when city cameras find a defect at the connection, or with a building permit that adds 400 or more square feet or two or more plumbing fixtures.
