A regional real estate trade group published a chart in 2023 telling agents that San Jose does not require a sewer lateral inspection before a home sale. The City of San Jose's own inspection program had already been mandatory for a year by the time that chart went out. Both of those things are true at the same time, which is exactly the problem for anyone trying to sell a house in San Jose right now.
If you're listing a home built before 2007 anywhere in the city, you are very likely subject to the Private Sewer Lateral Pipe Inspection Program, known as PSLP, which has required a professional inspection and certification before closing on any residential sale since June 2022. Miss it, and the sale does not close. Assume it doesn't apply to you because a chart, a friend, or a five-year-old blog post said otherwise, and you find out the hard way, mid-escrow, with a buyer's lender waiting on paperwork nobody told you to get.
What the ordinance actually requires
PSLP is not a suggestion. Since June 2022, the City of San Jose has required that sewer laterals, the underground pipes connecting a house to the public sewer main, be professionally inspected and certified before most residential property sales can proceed. The inspection itself is a camera run through the line, checking for cracks, root intrusion, offset joints, and the kind of structural failure that isn't visible from the yard.
San Jose splits responsibility for the line in a way that matters once repairs come up. The homeowner is responsible for the upper lateral, running from the house to the property line. The city takes responsibility for the lower portion, from the property line to the main, but only once an approved property line cleanout has been installed. That cleanout is a four-inch access point within five feet of the sidewalk, and installing one requires its own permit and city inspection before backfill.
Not every plumber can sign off on this. Inspections of this kind typically require certification through the National Association of Sewer Service Companies, so a general handyman camera run doesn't satisfy the requirement.
Who's actually exempt
The exemption list is short, and it's built almost entirely around the age of the home, which is worth sitting with for a moment.
| Exemption | What it means |
|---|---|
| Home built after June 2007 | Falls within 15 years of the June 2022 mandate and is exempt |
| Not connected to city sewer | Septic systems are outside the program |
| Gift to immediate family | Non-sale transfers don't trigger the requirement |
| Refinance without ownership change | Title updates alone don't count as a sale |
| Valid certificate within 10 years | A prior passing inspection carries forward |
Look at that first line again. The exemption is tied directly to construction age. That single fact is the reason this ordinance lands so unevenly across San Jose, and it's the reason a seller in a newer subdivision can shrug this off while a seller three miles away cannot.
Why some blocks carry this and others don't
San Jose's oldest neighborhoods still run largely on the plumbing they were built with. Naglee Park, Willow Glen's historic core, the Rose Garden district near Naglee Avenue, and pockets of Cambrian Park were built between the 1920s and the 1950s with vitrified clay sewer laterals, a material that was standard through the mid-twentieth century because it resists corrosion but fails at the joints as soil shifts and roots find their way in. Clay pipe has an expected service life of 50 to 100 years, which means laterals in these neighborhoods are now at or past the point where a passing inspection is anything but guaranteed.
The mid-century tract belt tells a similar story with a different material. Homes built through the 1950s and 1970s in Almaden Valley and the broader Cambrian and Blossom Valley area often run on a mix of clay and cast iron, and some Santa Clara Valley homes from that era used Orangeburg pipe, a bituminous fiber material that was cheap to install during the postwar building boom but deforms and collapses with age.
A failed lateral is not a minor line item. Replacement typically runs $8,000 to $25,000 depending on length, depth, and access, according to local sewer contractors who work these neighborhoods regularly. That's the number a seller in an older section of town needs to have in their head before they price a listing, not after an inspection report shows up during escrow.
Not every South Bay city plays by the same rules
This is where the 2023 trade group chart becomes more than a curiosity. It listed San Jose alongside Los Gatos and Saratoga as cities that do not require sewer lateral inspections at time of sale. Multiple current sources, including licensed plumbing contractors who handle PSLP paperwork for a living, describe San Jose's program as mandatory and unambiguous since June 2022. One of those two things is outdated, and a seller who trusts the wrong one loses time they don't have once they're under contract.
Morgan Hill runs its own Private Sewer Lateral Ordinance, effective the same month as San Jose's, June 1, 2022, but with a meaningfully different rule. There is no split responsibility there. The homeowner is on the hook for the entire lateral, upper and lower portion alike, and only NASSCO-certified firms are permitted to perform the inspection.
"It's a big ticket item so it's important to get ahead of that."
That's the kind of advice that gets repeated across the industry, and it's correct. The problem is that knowing to get ahead of it requires knowing which ordinance applies to your specific address, not the city next door.
Properties inside the West Valley Sanitation District, which covers Campbell, Los Gatos, Saratoga, and Monte Sereno, follow a separate cleanout permit process through that district, with its own review and a $425 processing fee. That's a different requirement from San Jose's PSLP, and conflating the two is exactly how a seller ends up surprised.
What this means if you're listing this year
The fix here isn't complicated, but it has to happen before the property hits the market, not after an offer comes in.
- Confirm your home's construction date. If it was built after June 2007, you're likely exempt from PSLP outright.
- Check whether a valid inspection certificate already exists for the property. A certificate issued within the past 10 years carries forward and saves you the step entirely.
- If neither applies, schedule a NASSCO-certified camera inspection before you list, not after you're in contract. A passing result becomes part of your disclosure package. A failing result gives you time to price the repair into your strategy instead of negotiating it under deadline pressure.
- Confirm which jurisdiction actually governs your parcel. San Jose's PSLP, Morgan Hill's PSL ordinance, and West Valley Sanitation District's cleanout permit process are three different systems with three different triggers, and an address a few blocks apart can fall under a different one.
FAQ
Does PSLP apply if I'm not planning any repairs and just want to sell as-is? Yes. The inspection requirement is triggered by the sale itself, not by whether you intend to fix anything. A failing inspection typically needs to be resolved, or the responsibility for the repair explicitly negotiated with the buyer, before the city will issue clearance.
My home was built in 1965. Does the 15-year exemption help me at all? No. The exemption only covers homes built within 15 years of the June 2022 mandate, meaning construction after June 2007. A 1965 build falls well outside that window and should be assumed subject to PSLP unless a valid certificate already exists.
If my lateral fails inspection, can the buyer take on the repair instead of me? That's a negotiation point in escrow, not something the ordinance dictates. Some sellers credit the buyer at closing, others complete the repair before the sale finalizes. Either path requires the city's clearance before title transfers.
A sewer lateral inspection is not the kind of thing most sellers think about until it's already holding up their closing date. If you're weighing a sale in Willow Glen, Naglee Park, Cambrian, Almaden, or anywhere else in San Jose's older housing stock, get ahead of this one before it gets ahead of you.
