What happens: standby crews respond to emergencies around the clock; they check the main and clear it if necessary, and clear a stoppage between an accessible property-line cleanout and the main as a courtesy
The City pays for part of this pipe. The owner cleans and maintains the whole lateral from the house to the main, but reconstruction and repair of the street portion - beyond the first joint after the property line - is the City's - but the code makes that duty "subject to compliance with" its cleanout section, so the fitting is what the City's share rests on. A street-side blockage will usually be cleared by City crews, though the City calls that a courtesy rather than a duty. Cupertino Sanitary District also names Los Altos among the communities it serves, and answers the same question its own way.
- Los Altos
- The reconstruction and repair of the street portion, conditionally, and no part of the cleaning. The code states that "the city shall be responsible for the reconstruction and repair of all lateral sewers subject to compliance with Section 10.04.250 of this article" - and 10.04.250 is the cleanout section, which requires a cleanout where the building sewer joins the lateral sewer, maintained watertight, under an approved box set flush with the ground. On its website the City puts the same split without the condition: it "is responsible for re-construction from the first joint after the property line to the main sewer line", and "is not responsible for any plumbing bills except when a street lateral requires reconstruction or repair". On a defect found during a blockage, "the City will repair it if the defect is beyond the first full section of pipe past the cleanout". Clearing a blockage is different: crews "will clear the stoppage as a courtesy if the blockage is between the property line cleanout (if accessible) and the main sewer line" - the City's own word is courtesy, so this is not a maintenance duty and should not be relied on as one.
- The property owner
- The cleaning and upkeep of all of it, and the reconstruction of the house side. The City states that "Los Altos residents are responsible for the maintenance of sewer laterals from their home to the main sewer line, which is typically in the street", and that the owner "is responsible for cleaning and maintaining the street and house lateral all the way to the main sewer, except for reconstruction and repair" - with reconstruction of the length "from the first joint after the property line to the home" also the owner's. Where a contractor cannot clear a stoppage because of a defect, the owner is responsible for the repair unless the defect lies beyond the first full section of pipe past the cleanout.

What to do: Ask Public Works whether the work you have in mind needs a written permit before booking a plumber, because the section is written broadly enough to reach work on private ground. If the property sits low, expect pumping to be the owner's cost, and expect the completed work to be water-tested with the superintendent present. First, though, confirm whether the address is on the City's sewer at all - Cupertino Sanitary District names Los Altos among the communities it serves and applies its own requirements where it collects, though its own service-area map draws its boundary along the city's southern edge rather than inside it.
Los Altos Municipal Code chapter 10.04, Sewer Service System GenerallyWhy this matters
The permit sentence has no threshold in it. No valuation, no length, and - unlike the permit rules in Burbank and Merced - no limit to the part in the street: it names any work on any lateral or building sewer. Read as written, that reaches a repair in your own garden. The low-house rule has no measurement in it: Milpitas, Burbank and Cupertino Sanitary District each publish a test you can check against a manhole rim, while Los Altos states the physics and leaves it to the superintendent - simpler to read, harder to plan against.
