Connecting to Santa Clara's sewer needs a written permit and the fees paid first: "no person whose premises are not now connected with the sewer system shall connect any premises or cause any premises to be connected with the sewer system without first obtaining a written permit to do so from the City and paying the established connection fees". There is also a deadline attached to availability rather than to notice - a property within 200 feet of a possible connection "shall be required to connect such premises to the sewer system within sixty (60) days from the date when a main sewer or lateral sewer located within the distance specified in this section is completed and available for connection". And each building needs its own: "there shall be a separate connection to the sewer system for each building or structure served", unless the Director permits otherwise in writing.

Who is responsible for which part

The whole pipe is yours, all the way to the City main, and the code says so in its definition: "each sewer lateral is owned by the entity that owns the property". No cleanout changes that. What a cleanout does change is what the City will do for you - with one at the property line, a City crew will check and clear the lower half at no charge; without one, the City says it "will not be able to assess the condition of the lower lateral to the main".

Santa Clara: The clearing of the lower lateral where there is a property line cleanout, and none of its repair. The City's sewer system management plan states that "the City will clear blockages from the property line clean out to the City sewer main", "as a service to the public; provided a property line cleanout exists and the City is made aware of any problems or backups", and that "Overall lateral maintenance and repair is sole responsibility of property owner". Its response procedure says the same in practice: where the stoppage is in the lower lateral, "The City will run a drain auger out to the city main in attempt to clear the blockage".
The property owner: Everything from the building to the City main. Section 13.10.020 defines a sewer lateral as "the sewer connection piping used to convey sewage from a building or facility on a parcel (private or public property) to the City-owned sewer main", and says that "each sewer lateral is owned by the entity that owns the property or facility from which that sewer lateral serves to convey sewage". Section 13.10.040 turns that into a duty: "each user shall keep his/her sewer connections and sewer lateral(s) in good order at his/her own expense and shall be liable for all damages resulting from failure to do so", and must keep it "free from displaced joints, open joints, root intrusions, substantial deterioration of pipe material, cracks, leaks, inflow or infiltration of extraneous water, grease and sediment deposits".

What else is worth knowing

Nothing splits the ownership or the repair of the pipe. The word "clean" does not appear anywhere in chapter 13.10, and no section of it gives the City a share of a lateral; the City's clearing comes from its management plan, not its code. What the cleanout at your property line changes is not who owns or repairs the pipe but what the City will come out and do. Its Sewer Problem page offers a free crew visit that includes a lower sewer lateral check from the property line to the sewer main through that cleanout, where one is available and accessible, and says that without one the City will not be able to assess the condition of the lower lateral. Two things follow for a reader. If you have a cleanout, ring the City before you ring a plumber, because the visit costs nothing and may end the problem. And if you do not have one, the City will install one for a published fee - but understand what you are buying, which is access and a free call-out rather than any share of the repair. That is the opposite of Roseville and Palo Alto, where a cleanout moves the responsibility itself. The City states all of this itself, in the sewer system management plan its Council adopted, under a heading reading "Lateral Responsibility": "property owners own the entire length of their laterals", "city employees do not work on the customer's upper lateral under any circumstances", and - the sentence worth reading twice if your house has just flooded - "the City is not responsible for damages due to blockages in these laterals". The plan also says what the cleanout buys you: "city employees will check the lower lateral provided that there is a property line cleanout", and if the stoppage is there, "the City will run a drain auger out to the city main in attempt to clear the blockage". A free clearing, not a share of the repair. The City adds that it "has been offering inexpensive clean out installations and to date has installed over 9,600", so if you do not have one, ask what it costs.

What the rules say

Most relevant if you are remodelling or adding a unit

Any timePermit
Connecting to Santa Clara's sewer needs a written permit and the fees paid first: "no person whose premises are not now connected with the sewer system shall connect any premises or cause any premises to be connected with the sewer system without first obtaining a written permit to do so from the City and paying the established connection fees". There is also a deadline attached to availability rather than to notice - a property within 200 feet of a possible connection "shall be required to connect such premises to the sewer system within sixty (60) days from the date when a main sewer or lateral sewer located within the distance specified in this section is completed and available for connection". And each building needs its own: "there shall be a separate connection to the sewer system for each building or structure served", unless the Director permits otherwise in writing.
What to do: Ring the Department of Public Works on 408-615-3000 before anything is designed and ask for the Sewer Connection Permit application and the current fee schedule. If the project is an ADU or a second structure, ask in the same call whether it can share the existing connection - that needs a written permit from the Director and the answer changes the budget. If your property is still on a septic system, ask whether a sewer is already available within 200 feet, because the sixty days may already be running.
Why this matters
Two of these three are the kind of requirement people meet late. The sixty days run from the day the sewer is available, not from the day anyone tells you, so a property on a septic system when a main goes in down the street is on a clock it may not know about. And the one-connection-per-building rule is what an accessory dwelling unit project runs into: sharing an existing connection needs the Director's written permit, and not sharing it means a second connection with its own fees. The City prices a City-laid lateral at $46,993 excluding the cleanout, a cleanout at the right-of-way line at $2,632 for 4-inch, and a treatment plant capacity fee of $1,187 a dwelling or $747 for an ADU. Worth knowing that the pipe you pay to install is then yours to the main for the life of the property.

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 main; your water line stops being yours at the meter.
