San Mateo's older sewer laterals
Pre-1980 housing here is 71%, above the California figure of 57%. That ranks 45th highest of the 151 California cities we profile. Clay pipe lets roots in at the joints, cast iron scales and cracks, and the line from the house to the street belongs to the homeowner in most places.
Only 41% of homes are single-family detached, so many sewer problems involve a shared building line. Check with your HOA or landlord before booking work.
In California: Seismic rules require water heaters to be strapped, and older homes often still have galvanized supply lines and cast iron or clay sewers.
Permits
Excavation in the yard or street needs a permit, and someone has to call 811 first to get utilities marked.
