Should You Get a Sewer Inspection Before Buying a House in San Jose?

Yes, for most South Bay homes, and especially for older ones. A general home inspection usually doesn’t run a camera through the sewer line, yet in San Jose the buyer becomes responsible for the whole sewer lateral, from the house to the City main in the street.

A camera inspection typically costs $300 to $600 here; replacing a lateral typically costs $6,000 to $15,000, so it’s worth knowing which one you’re buying before your contingency ends.

Most South Bay cities, San Jose included, have no point-of-sale sewer rule, so the inspection is up to you. Morgan Hill is the exception: it requires a camera inspection of the lateral before most homes are sold.

Do South Bay Cities Require a Sewer Inspection at Sale? (Checked October 2026)

Berkeley runs its own lateral program, and Fremont, served by Union Sanitary District, is outside EBMUD’s regional program.

Why Scope the Sewer Before You Buy?

• The lateral becomes yours. The City of San José puts “the entire lateral” on the property owner. In San Jose, the City clears and repairs the street section at no charge only once an approved property-line cleanout exists; without one, the buyer inherits all of it. See who is responsible for the sewer lateral in San Jose.
• A home inspection won’t see it. Most general inspections run water through the drains, which shows a slow drain but not a cracked pipe 30 feet out in the yard.
• Older South Bay laterals are often near the end of their life. Many homes built from the 1950s to the 1970s still have their original clay or cast-iron laterals, and mature street trees send roots into loose joints.
• The numbers are lopsided. In San Jose, a camera inspection typically costs $300 to $600, while a spot repair runs $2,000 to $5,000, a full lateral replacement $6,000 to $15,000, and long, deep or street work $15,000 to $20,000 or more.

What Does a Sewer Camera Find?

A plumber feeds a waterproof camera on a flexible cable through a cleanout and records the line out to the main. A transmitter in the camera head lets a locator above ground mark where and how deep a problem sits. The video shows:

• Root intrusion at joints, from a few hair roots to a pipe packed solid
• Cracks, breaks and holes, common in old clay and corroded cast iron
• Offset or separated joints, where soil movement has pulled sections apart
• Bellies (sags), low spots that hold water and debris
• Collapsed sections that need digging or pipe bursting
• Grease, scale and debris that cleaning can clear
• Pipe material changes and old repairs, which hint at the line’s history
• Cross bores, where a gas line was bored through the sewer pipe during utility work; EBMUD warns about them, and the camera can show one before anyone runs a cutter through the line

When and How Should a Buyer Schedule It?

1. Book it early in your inspection contingency, so there’s time to get repair prices and negotiate before the deadline.
2. Ask the seller’s agent about access. The plumber needs to get into the house or yard, and an accessible cleanout makes the inspection faster and less invasive. If there’s no cleanout, ask the plumber how the camera will get into the line; our free coupon inspection needs an accessible mainline cleanout.
3. Be there if you can. Watching the video with the plumber is the fastest way to understand what’s minor and what isn’t.
4. Ask before you book whether a copy of the video comes with the report. Our free coupon inspection doesn’t include one; if you’ll need footage for your agent or the seller, ask about it when you schedule.
5. Get findings in writing, with the distance from the cleanout to each problem, whether it’s on your lot or under the sidewalk or street, and a written price for the fix.

What If the Inspection Finds a Problem?

Talk to your agent about your options; buyers commonly ask the seller to repair, give a credit or lower the price. A written price for the specific repair makes that conversation concrete. We quote each repair as a fixed price before we start: cleaning or hydro jetting for roots and grease, a spot repair for one bad section, lining or bursting through small pits (trenchless sewer repair), or a full lateral replacement.

If the seller makes the repair, ask for the permit and the final inspection. In San José, repairing or replacing a building sewer or installing a property-line cleanout takes a plumbing permit, and the City requires a property-line cleanout whenever the building sewer is replaced or repaired at the property line.

Buying in Morgan Hill?

Morgan Hill’s private sewer lateral ordinance puts the inspection on the seller. The seller starts with the City’s online Kickoff Form and hires a Qualified Contractor from the City’s list, who records a CCTV inspection, typically from the cleanout nearest the building to the main. If the lateral passes, the City issues a Certificate of Compliance within five business days, valid for ten years. If it fails, the repairs can be made by any licensed plumbing contractor with a Morgan Hill business license, and a Qualified Contractor re-inspects. To keep the sale on schedule, buyer and seller can instead sign a Transfer of Responsibility: the buyer then has 180 days after utility service is turned on to finish the repairs, and the City can impose penalties or end water service if they aren’t done. Newer homes file an Exemption Form instead. CPI is not on the Qualified Contractor list, so we don’t perform these inspections; the City publishes the list. See sewer line replacement in Morgan Hill.

Buying in the East Bay?

In EBMUD’s regional program cities, the lateral needs a Compliance Certificate before title transfers, and buyer and seller negotiate who gets it. EBMUD issues it after witnessing an air or water verification test; its staff don’t review camera video, though most owners have the line scoped first to see what work is needed. If the work can’t be finished before closing, a Time Extension Certificate gives 180 days from its issue date, with a $4,500 refundable deposit.
