- Who issues it:
- Town of Los Gatos
- What it covers:
- temporary use of the public right-of-way for private construction, naming sewers twice
The Town of Los Gatos requires an encroachment permit "whenever temporary use of public right-of-way is requested for private construction work", naming "laying or placing any pipes, conduits, sewers" and "connecting to or altering in any way any Town drainage system, sewer system, or piping system of any kind" among its examples. It asks for the cost of the work, the State Contractor's and Town Business License numbers, a site-specific sketch, a diversion plan, insurance and an Engineer's Estimate. It also publishes a coordination list of other agencies whose permits may be needed - police traffic control for "any work at or within 150 feet of a signalized intersection", Caltrans "when working on a Town street that is also a State Highway", plus VTA, Valley Water and County Fire - warning that "permits from other agencies may require a significant lead time".
- Who issues it:
- West Valley Sanitation District
- What it covers:
- connecting to the District's sanitary sewer system, which needs a sewer connection permit or a wastewater discharge permit
West Valley Sanitation District's ordinance code states that "it shall be unlawful for any person to discharge or deposit any substance or connect to the district's sanitary sewer system without a valid sewer connection permit and/or wastewater discharge permit issued by the district pursuant to this code". It also provides that "the requirement to install a property line cleanout shall be imposed by the district for any work requiring a district permit, or when in the district manager's opinion, the lower sewer lateral has experienced a high frequency or severity of blockages, or when an existing property line cleanout is deemed not to conform with district design standards". As amended by Ordinance 156 (9 September 2026), the code also provides an alternative: the cleanout, which the code calls the "PLCO", is required "unless the property owner files with the district a properly executed district release of liability for the maintenance, cleaning, and repair of the PLCO and lower lateral".

Who is responsible for which part
The District's ordinance code says "the lower sewer lateral is owned by the district" - the run from the property line cleanout to the sewer main in the street. On who maintains it, the code says more than one thing. It says the District "will maintain" the lower lateral and "is generally responsible for the maintenance, cleaning, inspection, repair, and replacement" of it. But for lower laterals and cleanouts installed before 1 November 2026, a further sentence reads "the district may continue to maintain, clean, inspect, and repair existing lower sewer laterals", on conditions, and the code does not say how these fit together. Where your side ends is not fixed either. The code's definition puts it at the cleanout, the cleanout included, "unless otherwise provided by district ordinance or policy", and another section names both the cleanout and the connection at the public sewer. Without an approved, accessible cleanout, the maintenance of the whole run to the main is yours. Confirm with the District where your side ends and whether it will maintain, repair or replace the rest before relying on it.

- The lower lateral: "the portion of a building sewer extending from the property line cleanout (PLCO) to the connection with the public sewer main", in the public right-of-way. The code says "the lower sewer lateral is owned by the district". Its provisions on maintaining it do not say the same thing. The lower-lateral definition says the District "is generally responsible for the maintenance, cleaning, inspection, repair, and replacement of the lower sewer lateral from the property line to the public sewer, subject to the provisions of this code". It then says that for lower laterals and PLCOs installed before 1 November 2026, "the district may continue to maintain, clean, inspect, and repair existing lower sewer laterals, provided such facilities were properly permitted, and installed in accordance with applicable standards in effect at the time of installation, and safely accessible". That sentence is a "may", and it leaves out replacement. The cleanout definition says "the district shall be responsible only for the maintenance, cleaning, inspection, and repair of the lower sewer lateral from the PLCO to the public sewer", and its copy of the sentence for existing laterals reads "shall may continue". Section 6.100 says the District "will maintain that part of each building sewer lying within a public right-of-way (lower sewer lateral) from PLCO to the public sewer". It also says that "if a properly installed, maintained, and accessible property line cleanout exists" the District will remove blockages, remove or treat roots, and carry out "repair or replacement of all, or a part of the lower sewer lateral" when "replacement becomes more economical than the maintenance being performed by the district". The other condition in that sentence, "when its condition is deemed, by the district manager", is left unfinished in the code. The code does not say how these provisions fit together, so ask the District what it will do for your lower lateral.
- The property owner
- The code's definition makes property owners responsible for "the upper sewer lateral from the building to the PLCO including the PLCO, unless otherwise provided by district ordinance or policy" - PLCO being its name for the property line cleanout. Section 6.100(C) adds "any PLCO installed in the public right of way" between the two halves. A new cleanout goes "approximately two (2) feet behind the property line", or, where the site makes that impractical, somewhere the District approves, such as behind the curb or in the sidewalk. Section 6.100(C) also states: "The owner's operation and maintenance responsibility is from the building to the connection at the sanitary public sewer, or the PLCO closest to the public sewer." That names a second end point, and the code does not say when each applies. Where no approved cleanout is in place and kept clear for the District's staff, "the maintenance obligation for the entire building sewer and any resultant backup or sanitary sewer overflow due to the lack of maintenance shall be the responsibility of the property-owner", and "responsibility for the repair or replacement of the lower lateral located within the public right-of-way shall be determined by the district manager on a case-by-case basis". Where the lateral connects to a public sewer in an easement, "the entire sewer lateral, including any cleanouts, shall be the responsibility of the property owner".

- Who issues it:
- Town of Los Gatos
- What it covers:
- temporary use of the public right-of-way for private construction, naming sewers twice
The Town of Los Gatos requires an encroachment permit "whenever temporary use of public right-of-way is requested for private construction work", naming "laying or placing any pipes, conduits, sewers" and "connecting to or altering in any way any Town drainage system, sewer system, or piping system of any kind" among its examples. It asks for the cost of the work, the State Contractor's and Town Business License numbers, a site-specific sketch, a diversion plan, insurance and an Engineer's Estimate. It also publishes a coordination list of other agencies whose permits may be needed - police traffic control for "any work at or within 150 feet of a signalized intersection", Caltrans "when working on a Town street that is also a State Highway", plus VTA, Valley Water and County Fire - warning that "permits from other agencies may require a significant lead time".
What to do: Before booking anyone, check two things with Parks and Public Works: how far your frontage sits from the nearest signalised intersection, and whether your street is a state highway. Either adds an agency and a wait. Ask your contractor to confirm they hold a Town business licence as well as a state licence, since the application asks for both numbers. The no-fee permit the Town offers is for sidewalk work only and will not cover a trench.
Town of Los Gatos, Parks and Public WorksWhy this matters
The Town tells you about the other agencies rather than leaving you to find them. Two on its list can reach an ordinary lateral repair. Work within 150 feet of a signalised intersection may need traffic control by Town police officers, which is a cost few would anticipate on a residential job and 150 feet is further than it sounds. The Town Code is blunter than the guidance about why somebody from the crew cannot simply wave cars past: section 15.20.020 provides that "no person other than a designee of the Director of the Parks and Public Works Department, an officer of the Police Department, or a person authorized by the Chief of Police, or person authorized by law, shall direct or attempt to direct traffic by voice, hand or other signal". Nor will your contractor's van be treated like a utility's. The parking and standing exemption in the next section reaches "any vehicle of a Town Department or public utility while necessarily in use for construction or repair work", and a private contractor repairing a private lateral is neither. And if your street doubles as a state highway, Caltrans issues its own encroachment permit on top of the Town's. The Town's own warning about lead time is the practical point: these are sequential, not parallel. West Valley Sanitation District's permit for the sewer work itself is separate again.
- Who issues it:
- West Valley Sanitation District
- What it covers:
- connecting to the District's sanitary sewer system, which needs a sewer connection permit or a wastewater discharge permit
West Valley Sanitation District's ordinance code states that "it shall be unlawful for any person to discharge or deposit any substance or connect to the district's sanitary sewer system without a valid sewer connection permit and/or wastewater discharge permit issued by the district pursuant to this code". It also provides that "the requirement to install a property line cleanout shall be imposed by the district for any work requiring a district permit, or when in the district manager's opinion, the lower sewer lateral has experienced a high frequency or severity of blockages, or when an existing property line cleanout is deemed not to conform with district design standards". As amended by Ordinance 156 (9 September 2026), the code also provides an alternative: the cleanout, which the code calls the "PLCO", is required "unless the property owner files with the district a properly executed district release of liability for the maintenance, cleaning, and repair of the PLCO and lower lateral".
What to do: If the District requires a cleanout, the code gives you "up to three hundred sixty-five (365) calendar days from the date of issuance" where the permit is mainly for other work, and "sixty (60) calendar days" where the permit is specifically for the cleanout. The installation must be done by a contractor registered with the District. Ask which deadline applies when the permit is issued, not later. The code's alternative to the cleanout is "a properly executed district release of liability for the maintenance, cleaning, and repair of the PLCO and lower lateral", and it says nothing more about that release. Ask the District what filing one would mean for the maintenance of your lower lateral before choosing it.
West Valley Sanitation District Ordinance CodeWhy this matters
That cleanout bears on where your side of the pipe ends. Without an approved one kept clear for the District's staff, the code puts "the maintenance obligation for the entire building sewer" on you, out to the main, and leaves the repair or replacement of the lower lateral under the street to the district manager, case by case. With one, the code's definition of the cleanout ends your side at it, the cleanout included, "unless otherwise provided by district ordinance or policy" - though another section names the connection at the public sewer as an end point too, without saying which applies when. Past the cleanout, the code says the District "will maintain" the lower lateral, but for one installed before 1 November 2026 another sentence says the District "may continue" to, and the code does not reconcile the two. So ask the District where your side ends and what it will do for yours. The code also warns that "if a blockage in the lower sewer lateral or receiving main sewer is found to be caused by the property-owner's maintenance activities, lack of maintenance activities, and/or FOG, all district repair, liability and or maintenance costs associated with removal of the blockage will be the responsibility of the property-owner" - clear your own line badly, leave it unmaintained, or send fats, oils and grease (FOG) down it, and the District's bill for clearing its own comes to you.
Assistance programmes
West Valley Sanitation District Private Lateral Replacement Program
A loan, secured on the house, and interest-free: "an interest-free five-year term loan as a lien against your property, maximum amount of $3,500, is available for you as a homeowner to assist in replacing your failing, or failed building upper sewer lateral". Repayment is collected on the property tax bill and the lien released when it is repaid. Against a five-figure lateral replacement, $3,500 is a contribution rather than a solution - but it is interest-free money and the District waives its own permit fees for work done under the programme. The order is the District's and runs one way: application and CCTV, then approval, then thirty days to sign a contractor, then ninety "calendar days from the letter date to complete all the scope of work identified in the construction contractor's bid".
Narrower than most, and the limits are worth reading before hoping. The District offers it "for homeowners with single family residential properties and limited to only one sewer lateral per property and one property per homeowner for the life of the District's Private Lateral Replacement Program (PLRP)" - so a landlord with several houses can use it once, and a flat or a duplex is outside it altogether. It is for a lateral already in trouble rather than one you want replaced before it fails: the loan assists in "replacing your failing, or failed building upper sewer lateral located on your property that connects to a District sewer main located in the public right-of-way". Money is not guaranteed by qualifying - "funding is available on a first-approved, first-served basis". There are deadlines once you are in: thirty calendar days from being notified of approval "to secure a contract with a construction contractor that meets the District requirements", and a CCTV inspection of the lateral is part of getting there.
