Should I Get a Sewer Inspection Before Buying a Home in Pasadena?
Listed by May Kunka of Compass in Pasadena
I generally recommend considering a sewer inspection when buying a single-family home in Pasadena, particularly with an older property. A standard home inspection usually doesn't tell us what's happening throughout the underground sewer lateral. That's important because the City of Pasadena says the property owner is responsible for the lateral running from the home all the way to its connection with the city's sewer main.
You found a beautiful 1920s Pasadena house.
Original hardwood floors.
Built-ins.
Batchelder-style fireplace.
Beautiful backyard.
Then I tell you:
"I think we should inspect the sewer."
Not nearly as exciting.
But it may be one of the more useful inspections we order.
Sewer lines are a perfect example of something buyers don't really think about until there's a problem.
You can't see them.
They're underground.
Everything might appear to be draining normally.
And then a camera goes down the line and suddenly we're having a very different conversation.
What Is a Sewer Inspection?
A sewer inspection typically involves running a specialized camera through the property's sewer lateral so the inspector can see inside the pipe.
We're looking for things like:
Tree-root intrusion.
Cracks.
Breaks.
Corrosion.
Offsets between sections.
Deterioration.
Blockages.
Bellies or low areas.
Older pipe materials.
Previous repairs.
Other conditions that could affect how the line functions.
Instead of guessing about what's underground, we're actually taking a look.
Doesn't the Regular Home Inspector Check the Sewer?
A general home inspector will usually test plumbing fixtures and may identify visible drainage problems.
But that's different from running a camera through the underground sewer lateral.
The sinks can drain.
The toilets can flush.
The shower can appear perfectly normal.
That doesn't necessarily tell us what the line looks like 30 feet away from the house.
That's why I think of the sewer inspection as a separate investigation.
Who Is Responsible for the Sewer Line in Pasadena?
This is where the local part becomes important.
The City of Pasadena says it is responsible for the sewer main running through the street.
But the lateral from the home or business to its connection with that main is the property owner's responsibility.
So don't assume:
"If something goes wrong underground, the city fixes it."
That depends on where the problem is.
If it's your lateral, it may be your responsibility.
Why Do I Recommend Sewer Inspections on Older Pasadena Homes?
Pasadena has a lot of older homes.
And I love them.
But an older house can have an older sewer system too.
Maybe the kitchen has been remodeled.
Maybe the electrical panel has been replaced.
Maybe the roof is five years old.
Maybe the bathrooms look brand new.
None of that tells me when the sewer lateral was last replaced.
That's why I don't let a beautiful renovation distract me from investigating the less glamorous parts of the property.
What Can Go Wrong With a Sewer Lateral?
Quite a few things.
Tree Roots
This is a big one.
Pasadena is known for mature trees and beautiful landscaping.
Unfortunately, roots and sewer lines don't always make great neighbors.
Roots can find openings in older pipe joints and work their way into the line.
Sometimes there's minor intrusion.
Sometimes there's a lot.
The important question is what the inspector sees and what they recommend doing about it.
Cracked or Broken Pipe
A camera may reveal cracks or damaged sections.
The significance depends on the location, material, extent of the damage, and other factors.
This is when I may want a sewer contractor involved rather than trying to interpret everything ourselves.
Offset Joints
Sections of pipe may no longer line up correctly.
That can affect flow and potentially allow roots or debris into the line.
Again, severity matters.
Not every imperfection means:
"Replace the entire sewer immediately."
A Belly in the Line
A low spot can allow water or waste to collect rather than flowing properly.
How significant that is depends on the situation.
Older Materials
The material itself may tell us something about the age of the system and its expected condition.
An older sewer line isn't automatically defective.
But I want to know what we're buying.
What Happens During the Inspection?
The sewer inspector typically needs an appropriate access point.
Then a camera is run through the line while the inspector watches the footage.
Ideally, I want to know:
What material is the line?
What condition is it in?
Were roots found?
Any cracks?
Any offsets?
Any standing water?
Can the inspector see the connection to the main?
Are there areas they couldn't inspect?
Does anything require further evaluation?
And if there's a problem:
How significant is it?
What If the Inspector Finds Tree Roots?
Don't panic.
Tree roots don't automatically mean the house has a catastrophic sewer problem.
I want more information.
How much intrusion?
Where is it?
What material is the pipe?
Can it be cleaned?
Is this routine maintenance?
Is there evidence of damage?
Is replacement recommended?
This is why I don't love inspection reports being reduced to:
Good or Bad.
Most houses aren't that simple.
What If the Sewer Needs Repair?
Then we investigate further.
Depending on your contract and remaining contingencies, we may potentially:
Ask the seller to repair it.
Request a credit.
Ask for a price adjustment.
Obtain additional estimates.
Accept the condition.
Or reconsider whether you want to proceed.
Which approach makes sense depends on:
The severity of the issue.
The cost.
The property's price.
How competitive the purchase was.
What else we've discovered.
And how much you want the house.
Should I Ask the Seller to Replace an Old Sewer Just Because It's Old?
Not necessarily.
Old doesn't automatically mean failed.
This is something I remind buyers about with older homes in general.
A house built in 1925 is going to have components with age.
Our goal isn't to turn it into a brand-new 2026 house during inspections.
Our goal is to identify material problems, understand what you're buying, and determine whether there are repairs or costs you need to prepare for.
If the sewer is functioning and the inspector doesn't identify a significant defect, age alone doesn't necessarily mean the seller should replace it.
Can I Ask for a Sewer Credit Instead of a Repair?
Potentially.
Sometimes I prefer credits because they give the buyer control over the work after closing.
But there are several things we need to consider.
Will your lender allow the credit?
How much are your allowable closing costs?
How serious is the sewer issue?
Does the work need to happen before closing?
Is the seller willing to negotiate?
A $10,000 sewer problem doesn't automatically mean we can simply write:
"$10,000 credit."
We need to structure the request around the actual transaction.
What If the Seller Already Has a Sewer Inspection?
Great.
I want to see it.
When was it performed?
Who performed it?
Is there video?
Did the inspector reach the city connection?
Were repairs recommended?
Were those repairs completed?
Do we have invoices?
Depending on the age and quality of the report, you may still decide to obtain your own inspection.
Seller-provided reports are useful.
But I still want you making an informed decision about your own due diligence.
Should I Inspect the Sewer on a Newly Remodeled House?
I would still consider it.
A beautiful remodel tells me the house was remodeled.
It doesn't necessarily tell me what happened underground.
I've seen plenty of homes where buyers are focused on:
Quartz countertops.
New appliances.
New bathrooms.
New flooring.
Fresh paint.
Meanwhile, some of the most expensive potential issues aren't visible in the listing photos.
That's why inspections matter.
What If the House Has Never Had a Sewer Problem?
That's good information.
It isn't the same as an inspection.
A seller can honestly say:
"We've lived here for 25 years and never had a backup."
Great.
I'd be happy to hear that.
But that doesn't tell me exactly what the pipe looks like today.
Both pieces of information can be useful.
Can the City Tell Me the Condition of My Sewer Lateral?
Remember, Pasadena distinguishes between its sewer system and the privately maintained lateral.
The City says it maintains approximately 320 miles of sewer line and cleans city lines on a regular schedule, but the property owner is responsible for the lateral from the building to the city main.
So the fact that the city's sewer main is maintained doesn't tell us the condition of the private lateral serving the house you're buying.
That's the part we're investigating.
Is a Sewer Inspection Required to Buy a Pasadena Home?
A sewer inspection isn't something I would describe as universally required for every Pasadena purchase.
The question is whether it's a sensible part of your investigations.
For many single-family homes, particularly older ones, I think it's worth considering because the line is underground, its condition isn't obvious, and the private lateral is the owner's responsibility.
What If I'm Buying a Condo?
That's different.
With a condominium, we need to understand exactly what portions of the plumbing and sewer system are the individual owner's responsibility and what belongs to the HOA.
That can depend on the governing documents and the physical setup of the property.
I wouldn't automatically treat a Pasadena condo the same way I treat a detached single-family home.
How Much Does a Sewer Inspection Cost?
Pricing varies by company and the specifics of the property.
Rather than quoting a number that may not apply to your home, I prefer getting a current quote from the inspector we're considering.
The bigger question for me is:
Is the information worth the inspection cost?
When you're buying a Pasadena home that may cost well over $1 million, spending money on appropriate due diligence can be a very small part of the overall purchase.
Pasadena's median sale price was about $1.23 million over the three months ending August 2026.
I'd rather know what we're dealing with before closing.
Should I Skip the Sewer Inspection in a Multiple-Offer Situation?
Don't assume that making a competitive offer means you have to stop investigating the property.
Pasadena remains somewhat competitive. Redfin reports that 51.3% of homes sold above asking over the three months ending August 2026, and some homes continue to receive multiple offers.
But competition doesn't make an underground sewer problem cheaper.
If we're trying to make your offer more competitive, let's talk strategically about:
The inspection contingency.
Timing.
Seller-provided reports.
Pre-offer inspections where practical.
What risks you're comfortable accepting.
I don't want you casually giving up information just because there are other buyers.
What Other Inspections Should I Consider on an Older Pasadena Home?
It depends on the property and what the general inspection reveals.
We might consider specialists for:
Sewer.
Foundation.
Roof.
Chimney.
Electrical.
Plumbing.
HVAC.
Termites.
Drainage.
Pool or spa.
Other property-specific systems.
That doesn't mean we're ordering ten inspections on every house.
We look at the property first.
Then we decide what deserves a closer look.
Frequently Asked Questions
Should I get a sewer inspection before buying a home in Pasadena?
I generally recommend considering one, especially for an older single-family home.
A sewer camera inspection can reveal conditions inside the private lateral that aren't visible during a standard home inspection.
Who is responsible for the sewer lateral in Pasadena?
The City of Pasadena says the city is responsible for the sewer main, while the property owner is responsible for the lateral running from the home or business to its connection with the main.
Does a regular home inspection include a sewer camera?
Typically, a standard home inspection and a sewer camera inspection are separate services.
Ask your inspector exactly what's included.
What problems can a sewer inspection find?
A sewer camera may identify root intrusion, cracks, damaged or offset sections, standing water, blockages, deterioration, older materials, and other visible conditions within the line.
Should I buy a house with roots in the sewer line?
It depends on the extent of the intrusion and the condition of the pipe.
Roots may sometimes be manageable with maintenance, while more significant intrusion or damaged piping may require repair or replacement. Have the condition evaluated before deciding.
Can I ask the seller for a credit if the sewer has problems?
Potentially.
Your options depend on your purchase agreement, remaining contingencies, the severity of the problem, lender limitations, and what the seller is willing to negotiate.
Does the seller have to replace an old sewer line?
Age alone doesn't necessarily mean a sewer lateral needs replacement.
The more useful question is what condition it's in and whether a qualified professional recommends repair or replacement.
So What's the Next Step?
When I'm helping you buy an older Pasadena home, I don't want all of our attention going toward the things we can see.
The beautiful fireplace.
The original windows.
The hardwood floors.
The kitchen.
The backyard.
I also want to know what's happening with the less exciting stuff.
And yes, sometimes that means sticking a camera down the sewer.
The City of Pasadena makes the ownership responsibility pretty clear: the city takes care of its sewer main, while the lateral connecting your home to that main belongs to the property owner.
If we're buying the property, that responsibility is about to become yours.
That's why I want to know what we're inheriting.
Maybe the inspection comes back looking great.
Perfect.
Maybe there are some roots that need routine maintenance.
Good to know.
Maybe we discover a significant problem and need another estimate.
Also good to know.
The goal of inspections isn't to find a perfect house.
It's to make sure you understand the house you're buying.
After nearly 20 years helping buyers throughout Pasadena and the San Gabriel Valley, I've found that the least glamorous inspections can sometimes provide some of the most valuable information.
If you're thinking about buying a Pasadena home, I'd be happy to help you figure out which inspections make sense for the property, coordinate the investigation period, and make sure you have the information you need before moving forward.
