Why Morgan Hill's Sewer Lateral Rule Doesn't Apply Anywhere Else in Santa Clara County

A buyer under contract on a 1962 ranch in Morgan Hill gets a call from escrow three weeks before closing: the sewer lateral failed inspection, and repairs have to happen before the deed can transfer. A few miles north, a buyer closing on a nearly identical 1962 ranch in Los Gatos never hears the word "lateral" once. Same county, same era of pipe, same odds that the clay line under the slab has cracked somewhere along its run. Only one of those two transactions has a rule forcing the question into daylight.

Most people assume sewer lateral requirements are either a countywide thing or not a thing at all. Neither is true in Santa Clara County, and the gap between the two outcomes above is not about the house. It is about which side of a city line the house happens to sit on.

The rule everyone assumes is countywide

Santa Clara County does not have a single, unified point-of-sale sewer lateral ordinance. Instead, each city sets its own policy, and the policies split the county roughly into two camps: one city that mandates inspection and repair before a sale can close, and several others, including the county's largest city, that leave it entirely to the buyer's own due diligence.

Here is what the record actually shows, city by city:

That table is the whole story in miniature. Morgan Hill stands alone. Everywhere else on this list, including San Jose, a home can pass through escrow without a single sewer camera ever running through the line.

What Morgan Hill actually requires

Morgan Hill's Water Conservation Ordinance and its Private Sewer Lateral Ordinance both took effect on June 1, 2022, and both attach to a home sale. Sellers are required to have the lateral inspected and any needed repairs completed before the transaction closes. The Santa Clara County Association of REALTORS® has since consolidated the paperwork into a single Inspection Report Form that covers both requirements, which is worth requesting from your escrow officer the day a Morgan Hill listing goes under contract rather than the week before closing.

The homeowner in Morgan Hill also carries the full lateral, not just the portion closest to the house. Unlike San Jose or Palo Alto, where the city takes responsibility for the segment running through the public right-of-way, Morgan Hill puts the entire pipe, from the foundation to the main, on the seller's side of the ledger.

What the rest of the county doesn't require, and why that's not the same as safe

San Jose's sewer code draws a boundary at the property line. The homeowner owns and maintains the upper lateral; the city is responsible for the lower segment once it crosses into the right-of-way. That split matters for repair cost, but it does not create a mandatory inspection at the time of sale. A seller in San Jose can list, sell, and close without ever running a camera through the line, and plenty do.

Los Gatos and Saratoga go further in the other direction. Neither city has adopted any sewer lateral ordinance tied to a sale, according to the compliance chart maintained by HomeGuard and cited by the Silicon Valley Association of REALTORS®. There is no form, no trigger, no compliance deadline. Whatever is happening underground on the day of closing stays exactly as unknown as it was the day before.

Mountain View and Palo Alto sit in a middle position. Neither requires an inspection to sell a home, but both require one the moment a homeowner pulls a permit for a major remodel or an accessory dwelling unit. Palo Alto also splits ownership the same way San Jose does, owner to the property line, city beyond it, according to reporting in Palo Alto Online. That means a Palo Alto or Mountain View seller who has never added a room or built an ADU may genuinely have no idea what condition the lateral is in, because nothing in their ownership history ever forced the question.

Where the rule came from

These ordinances did not appear out of an abundance of caution. Pacifica, on the San Mateo County side of the Peninsula, was the first Bay Area city to require lateral repairs at the point of sale after aging pipes were found discharging untreated sewage into groundwater and eventually the Pacific Ocean, according to Discount Plumbing Rooter's Joel Page in that same Palo Alto Online report. Cities that followed, including Morgan Hill, were responding to the same underlying problem: neighborhoods built 50 to 100 years ago often ran their laterals in clay or a fiber material called Orangeburg, both of which degrade with age regardless of whether anyone ever notices.

That history is worth knowing because it explains why the rule tracks with old housing stock rather than with price point. A newer build in any of these cities is far less likely to trip a repair requirement than a mid-century home, ordinance or no ordinance.

The number that matters more than the ordinance

The pipe's age is the real variable, and the ordinance only determines whether anyone is forced to look at it before money changes hands. Estimates for the work itself vary depending on scope. A straightforward camera inspection typically runs $300 to $750. Repairs range from a simple spot fix in the low thousands up to $25,000 or more for a full trenchless replacement on a long run, with trenchless methods commonly priced between $80 and $250 per foot. Most full Bay Area lateral replacements land somewhere between $8,000 and $18,000, though the spread across sources is wide enough that a seller should treat any single number as a starting estimate, not a quote.

A lateral that would fail an inspection today does not become safer to ignore just because your city does not require you to look at it.

That is the practical takeaway buried in the ordinance gap. The absence of a rule in San Jose, Los Gatos, Saratoga, Mountain View, or Palo Alto is not evidence that the pipes there are in better shape. It just means nobody is required to find out before the sale closes.

What this means if you're comparing two cities right now

Santa Clara County's median home sale price sat at $1.6 million over the three months ending in May 2026, down 4.9 percent from the same period a year earlier, with homes typically going under contract in about 15 days. In a market that still moves that fast, a sewer surprise discovered mid-escrow is one of the few things capable of derailing a closing date that both sides thought was locked in.

If you are weighing a home in Morgan Hill against a similar one in San Jose or Los Gatos, the ordinance difference is not a reason to avoid either city. It is a reason to budget your own inspection into the timeline regardless of what the local rule requires. In Morgan Hill, the seller has already done that work for you and the report should be part of your disclosure package. Everywhere else on this list, ordering your own camera inspection during the contingency period is the only way to know what you are actually buying, since no city agency is going to hand you that answer.

If you're selling this season

Sellers in Morgan Hill should treat the lateral inspection as a pre-listing task, not a closing-week scramble. A failed test discovered with three weeks left on the calendar turns a plannable repair into a rush job, and rush pricing on excavation work is real. Sellers everywhere else in the county have more flexibility, but flexibility is not the same as immunity. A buyer's inspector in San Jose or Palo Alto can still request their own lateral camera pass, and a seller who has one ready before it's asked for tends to keep more control over the repair conversation than one who is caught flat-footed in week two of escrow.

Frequently asked questions

Does a clean home inspection mean the sewer lateral is fine? Not necessarily. A standard general home inspection typically does not include a sewer lateral camera pass unless it is specifically requested or required by local ordinance. In cities without a point-of-sale rule, that inspection has to be ordered separately.

If my city doesn't require it, can I still ask the seller to inspect before I write an offer? Yes. Requesting a lateral inspection as part of your contingency period is standard practice regardless of whether the city mandates one, and it is a reasonable ask in any Santa Clara County transaction involving an older home.

Does the ordinance follow the house or the current owner? The requirement is tied to the transaction itself. In Morgan Hill, it activates whenever a sale closes, regardless of how long the current owner has held the property.

Ordinance gaps like this one are exactly the kind of detail that shows up nowhere on a listing sheet and everywhere in a closing timeline.
