Sewer Line Repair in South San Francisco, CA
The run from a building in South San Francisco out to the public main is the property owner’s responsibility, and in housing of this age it is the one material that cannot be ruled out by a date. There are 22,033 occupied homes here, and across all the housing the median build year is 1963 — the best single clue to what the pipe is made of and how it tends to fail.
In short
Bituminized fiber pipe — Orangeburg — went into the ground alongside clay across the years South San Francisco housing typically dates from, which is 1963. It deforms into an oval rather than cracking, so the pipe becomes the restriction and clearing it restores nothing.

What went in the ground around 1963
A lateral laid in South San Francisco in that period is most likely Orangeburg or cast iron, with clay still going in at some depths. Which of the three you have is not something the build year can settle on its own. More on Orangeburg pipe.
What a camera survey should settle here
Three materials were going in the ground at once in these years, so the survey is identifying the pipe before it diagnoses anything. The full picture on Orangeburg pipe.
South San Francisco is the 85th largest block of laterals we cover in California, carrying about 0.3% of the 6,643,412 homes on our CA list, and its housing runs older than 79% of the CA towns we route. Age concentration matters on a lateral: where a whole street went in one season, the failures arrive in one season too.
61% of homes here are owner-occupied — 8 points above the CA figure. That matters more on a lateral than on almost any other pipe in the house: the run from the building to the main is the property owner’s to repair, and a landlord and a resident owner do not find that out at the same speed.
Median household income across South San Francisco ZIP codes is $135,966 — context for a repair no homeowner can bill to anyone else.

Before anyone digs in South San Francisco, get the run on camera — and ask what the pipe is actually made of, because the build year cannot settle it at this age. What the recording should show you.
