  • When you remodel · Inspection

    San Carlos Municipal Code 13.05.040(B)(2) requires that all sewer laterals "shall be inspected ... upon the occurrence of any of the following, unless a valid certificate of sewer lateral compliance is on file with the City": a new connection; "application for a building permit for a building improvement"; work on the sewer main the lateral connects to; smoke testing of that main; or after "a sanitary sewer overflow resulting from blockage in a lower lateral". Inspection is by CCTV or three-dimensional photography and "shall not commence without a valid permit issued by the City".

Who is responsible for which part

It depends on one fitting. Put in an approved cleanout at your property line and get it accepted, and the City takes over the length from there out to the main - the part under the road, wye included. Without one, the whole lateral is yours.

San Carlos
The lower lateral, once there is an approved cleanout at the property line. The City states it plainly in its account of the wastewater system: "The property owner is responsible for the sewer lateral, but if an approved property line clean out is installed, the City assumes responsibility for the maintenance and repair of the lower portion of the laterals located within the public right-of-way." Its standard detail for that cleanout draws the same line: the sheet brackets the run either side of the cleanout, marking the main side the City's responsibility "upon approval and acceptance of installation" and the house side the property owner's, with the wye branch at the main falling on the City's side.
The property owner
Everything from the building to the cleanout - and, if you have no approved cleanout, everything to the main including the run under the road. The City states that "the property owner is responsible for the maintenance, repair, and replacement of their private sewer lateral", and its code defines a sewer lateral as "the sewer line beginning at the foundation wall of any building and terminating at the sewer main", including "the upper lateral and lower lateral together" - the lower lateral being "the portion of a sewer lateral lying within a public street connecting an upper lateral to the sewer main". Note that the code says who is responsible and never says who owns the pipe.

What decides which applies

The cleanout is the whole question here, and it is worth money. A cleanout at or near your property line, installed to the City's standard detail and accepted by the City, moves the length from there to the main onto the City. No cleanout, and that length stays yours. The detail puts it no more than five feet from "property line or back of walk whichever is closer to sewer main", and specifies the materials and the box. If you are having lateral work done anyway, this is the thing to ask your contractor to include and the City to accept. Two further points from the code. It treats a pressure lateral differently: "the maintenance responsibility for a private pressure lateral to the City sewer main shall always remain with the property owner", with no cleanout exception. And for a gravity lower lateral the Director of Public Works "shall have the sole discretion to determine whether the private gravity lower lateral is acceptable" - so acceptance is a decision somebody makes, not something that follows automatically from installing the fitting. Ask what the City needs to see before you pay for the work.

  • When you remodelInspection

    San Carlos Municipal Code 13.05.040(B)(2) requires that all sewer laterals "shall be inspected ... upon the occurrence of any of the following, unless a valid certificate of sewer lateral compliance is on file with the City": a new connection; "application for a building permit for a building improvement"; work on the sewer main the lateral connects to; smoke testing of that main; or after "a sanitary sewer overflow resulting from blockage in a lower lateral". Inspection is by CCTV or three-dimensional photography and "shall not commence without a valid permit issued by the City".

    What to do: Ask the City whether a valid certificate of sewer lateral compliance is already on file for the property - the whole chapter turns on that, and a certificate already filed removes the obligation at every trigger. If you are applying for a building permit, expect the lateral inspection to be a condition of it.

    Why this matters

    Two of the five triggers are not the owner's doing. The City repairing its own main, or smoke-testing it, starts an inspection obligation on the private lateral beside it - so the bill can arrive because of the City's maintenance schedule rather than anything the owner planned. And a sale is not among the five: neighbouring San Mateo, San Bruno and Millbrae each require a certificate when a property changes hands, and this chapter does not name a sale at all. That is a fact about this chapter, not a promise that nothing anywhere requires it.

Your other pipe: the water service line

The drinking water line coming into your property is a separate pipe, run by a separate authority, and who is responsible for it is decided separately. Your sewer lateral is yours to the cleanout; your water line stops being yours at the meter.
