Before you sign a listing agreement in Morgan Hill, ask a question that has nothing to do with your kitchen, your roof, or your lot size: what year was your house built?
That single number decides whether you owe the city two separate inspections before escrow can close, and it decides differently depending on which inspection you're talking about. Morgan Hill is one of the few cities in the South County and Silicon Valley corridor that requires a Private Sewer Lateral inspection and a plumbing fixture retrofit inspection at the point of sale, not at some vague future date, at sale. Most sellers find out about this from their agent or their title company partway through escrow. Some find out from a plumber standing in their front yard with a CCTV camera.
Here is what makes this genuinely tricky. The two ordinances that trigger these inspections don't use the same clock. One recalculates every year. The other has been frozen on a single date since before most of Silicon Valley's tech boom. A seller who assumes their home's status from three years ago still holds today can walk straight into a delay.
Two Ordinances, One Certificate, Two Different Logics
Both requirements came out of the same package, adopted by the city and effective June 1, 2022. Ordinance No. 2322 covers the Private Sewer Lateral, the pipe that carries wastewater from a house to the city's main line. Ordinance No. 2323 covers plumbing fixtures, meaning toilets, showerheads, and urinals. Both require a Certificate of Compliance before the city will turn on new water service for a buyer, which in practice means both have to be resolved before or during escrow.
Where they split is in how the trigger date behaves over time.
| Private Sewer Lateral (Ord. 2322) | Plumbing Fixtures (Ord. 2323) | |
|---|---|---|
| Applies to | Properties more than 15 years old | Properties built on or before January 1, 1994 |
| Threshold moves? | Yes, recalculated every year | No, fixed since the ordinance passed |
| Who inspects | NASSCO-certified contractor with a Morgan Hill business license | Any C-36 licensed plumber with a Morgan Hill business license |
| Certificate validity | 10 years | Not time-limited once fixtures are compliant |
That second row is the whole story.
The Clock That Moves Every January
The Private Sewer Lateral ordinance doesn't name a fixed construction year. It says a property is subject to inspection once it's "more than 15 years old," and the city recalculates what that means annually. Back in 2023, the cutoff was construction year 2008: anything built in 2008 or later was exempt, anything built in 2007 or earlier owed the inspection. As of this year, the city's own guidance places the cutoff at 2011, meaning homes built in 2011 or later are currently exempt.
Run that forward one year and the exemption disappears for an entire cohort of houses. A home built in 2011 is fine this year. Next year, once that home crosses the 15-year mark, it becomes subject to the same CCTV inspection as a house built in 1985, even though nothing about the plumbing changed. The house didn't get older in any way that matters structurally. The calendar just caught up to it.
If you own a home from the early-to-mid 2010s in a neighborhood like Madrone or one of Morgan Hill's newer subdivisions, that's the detail worth double-checking before you price a listing, not assuming last year's exemption status still applies.
For homes that do owe the inspection, the process is specific. A qualified contractor, meaning someone with a C-36 license, a City of Morgan Hill business license, and NASSCO certification, has to film the lateral from the clean-out closest to the house to the connection at the street. City staff reviews the footage and the report. If it passes, the Certificate of Compliance comes back in five business days, and it's good for ten years, so if your lateral was inspected any time in roughly the last decade, you may already be covered.
If it fails, the seller has two paths:
- Complete the repairs through any licensed plumbing contractor with a Morgan Hill business license (the NASSCO certification is only required for the inspection itself, not the repair), then schedule a second CCTV pass to confirm compliance.
- Negotiate a notarized Transfer of Responsibility with the buyer, which hands the repair obligation to them. If both parties agree to this, the buyer gets 180 days after utility activation to complete the work and submit a passing inspection. Miss that window and the city can apply penalties, including termination of water service.
That transfer option matters at negotiation time. A seller staring down a failed lateral inspection close to closing isn't necessarily stuck delaying the sale. They're stuck negotiating who pays for the fix and when.
The Date That Hasn't Moved Since 1994
The plumbing fixture ordinance works nothing like the one above. There's no rolling window here. The line is January 1, 1994, and it has stayed exactly there since the ordinance passed. If your house was built in 1993, it will owe a fixture retrofit at every future sale, permanently, regardless of what year that sale happens. If it was built in 1995, it never will, again permanently.
Two houses built a year apart, otherwise comparable, sit on opposite sides of a rule that will never reconsider itself. That's the trade-off in choosing a fixed date over a rolling one: it's predictable and simple to check, but it also means the gap between "exempt forever" and "obligated forever" is exactly one calendar year of construction, with no room to argue it either way.
For properties this rule catches, the retrofit is straightforward on paper: toilets, showerheads, and urinals manufactured in 1993 or earlier need to be swapped for EPA WaterSense-certified high-efficiency fixtures, verified by a licensed plumber, before the city issues a Water Conservation Certificate. One notable exemption sits inside the same form used for the sewer lateral inspection: a property connected to a private well, rather than city water, doesn't owe this inspection at all.
The Exemption Worth Reading Twice: Wells and Septic
That well exemption isn't a technicality for most of Morgan Hill's housing stock, but it matters a great deal on the rural fringe. Properties in areas like Paradise Valley, Holiday Lake Estates, and the South Coyote area routinely run on private wells and septic systems rather than city sewer and water, and both city ordinances carve out exemptions for exactly that situation. A property on a separate septic system, not connected to the city sewer main, doesn't owe the Private Sewer Lateral inspection. A property on a private well, not city water, doesn't owe the plumbing fixture retrofit either.
That doesn't mean rural South County sellers are free of paperwork. Private wells in Santa Clara County fall under the Santa Clara Valley Water District's own Well Ordinance 90-1, a separate regulatory track entirely, covering construction, destruction, and reconstruction of wells. Nearly all of the county's South County water supply comes from groundwater, which is why the district treats well permitting seriously enough to have just updated its fee schedule, effective January 1, 2026, the first increase since 2017. Starting February 1, 2026, the district also stopped accepting paper applications entirely, moving well permitting fully onto its CityWorks online portal. None of that touches a sale directly unless a well needs to be destroyed or reconstructed as part of the transaction, but it's the kind of detail that surfaces fast once escrow opens on a well-and-septic property.
What This Means If You're Listing Soon
The practical takeaway isn't complicated, but it does require checking rather than assuming. If your home was built before 2011, confirm whether you already hold a valid Certificate of Compliance from a past sale or inspection within the last ten years before you assume you need a new one. If your home was built in the early 2010s, don't rely on last year's exemption status, check where this year's rolling cutoff actually sits. If your home predates 1994, budget for the fixture retrofit as a known cost rather than a surprise. And if you're on a well or septic system outside city limits, the exemption paperwork still has to be filed, it's just a different form.
None of this is the kind of thing a general home-selling checklist covers, because none of it exists outside Morgan Hill's own municipal code. It's exactly the sort of local detail that turns into a delay when nobody flags it early, and exactly the sort of detail a team that closes deals in this specific city catches before it becomes a problem.

A few common questions:
Does every home sale in Morgan Hill require these inspections? No. New construction younger than the current rolling cutoff, homes already holding a valid Certificate of Compliance from within the last ten years, properties on septic or private well systems, and transfers that don't meet the city's legal definition of a "sale of property" can all qualify for an exemption, but the exemption has to be documented and filed, not assumed.
What if my lateral was inspected a few years ago for a different reason? If that inspection met city standards and happened within the last ten years, it likely still counts. Keep the paperwork. It's one of the few pieces of this process that doesn't reset every year.
Can I just let the buyer handle it after closing? Only with a notarized Transfer of Responsibility signed by both parties, and only if the buyer understands they'll have 180 days after utility activation to complete the repairs. Skipping that step, or missing that window, can put the buyer's water service at risk.
