Published Los Angeles prices put a sewer camera inspection at about $250 to $500, a backflow assembly test at about $75 to $150 and a plumber's general inspection visit somewhere in the low hundreds, often credited toward repairs. City permit inspections are charged inside the permit fee. All of these are guides, and the plumber we arrange gives a written quote after seeing the job. For the rules behind the work, see our overview of permits, codes and inspections.
What is a plumbing inspection?
The term covers two different things. A permit inspection is the city checking that new or changed plumbing meets code, and a plumber's inspection is a visit to look over a home's pipes, fixtures and water heater, often before a purchase or a remodel. A camera inspection is a third kind that looks inside a drain.
Permit inspection. LADBS requires a plumbing permit for installation or modification of drainage systems, fuel gas piping, and potable water piping, and inspections happen at stages such as rough plumbing, before walls close, and final. A city inspector does these, and the cost sits in the permit.
Plumber's inspection. A plumber checks supply and drain lines, fixtures, shutoffs, the water heater, pressure and visible leaks, and reports what needs attention. It suits a home you are buying or a house you suspect has old pipe.
Camera inspection. A small camera on a cable goes into a drain or sewer line to show cracks, roots, bellies and blockages, with video as a record. It is the only way to see inside buried pipe without digging.
What are typical plumber prices in Los Angeles for inspections?
Published prices from Los Angeles-area businesses put a standard sewer camera inspection at about $250 to $500, a backflow assembly test at about $75 to $150, and a general plumbing inspection visit at a few hundred dollars. National aggregator figures run higher, so test a quote against local ones.
| Service | Typical Los Angeles range | Notes |
|---|---|---|
| Sewer camera inspection | $250 to $500 | Often cheaper when bundled with drain cleaning |
| Pre-purchase sewer scope | $300 to $500 | A flat fee is common |
| Backflow assembly test | $75 to $150 | Wider range of about $50 to $250 |
| Backflow certification of a new assembly | From about $150 | Published by one Los Angeles tester |
| General plumbing inspection | Low hundreds | Quoted by scope, ask what the report includes |
A few of those figures come from a single business and national guides disagree, so use them as a check, not a rule. One aggregator lists a Los Angeles average far above local quotes, which suggests its averages include much larger jobs.
What pushes the price up or down?
Access, the length of the line, the number of fixtures, the age of the home and what you want in the report move the price. Getting into a sewer through a toilet instead of a cleanout adds cost, and a long line or a hard-to-reach assembly takes longer. Bundling two jobs on one visit often lowers the combined cost.
Other factors:
- Report and video. A written report with video and photographs costs more than a verbal summary. Ask for what you will actually use.
- Same-day or after-hours. Faster service often carries a premium.
- Credits. Some plumbers credit an inspection fee against repair work. Ask before you book.
- Findings. An inspection that finds a problem leads to a repair quote, which is separate.
Do not pick an inspector on price alone. A very low fee can mean no report, a short look or a plan to make money on repairs. Ask what is included and who does the work.
When is a plumbing permit required in Los Angeles?
LADBS requires a plumbing permit for any installation or modification of drainage systems, fuel gas piping, potable water piping and rainwater piping. Like-for-like repairs, such as swapping a faucet, are generally treated differently from new or altered piping, so ask LADBS or the plumber before starting. Gas piping always needs a closer look.
LADBS says a permit is needed for installing any gas piping, with a narrow exception for very short connections between an existing outlet and an appliance in the same room. LADBS says larger systems need plan check first. Which path applies depends on the job, and the plumber we arrange tells you at the quote stage.
A permit is not a one-time cost. LADBS says inspections are needed at each phase before moving to the next, and that regular inspections are requested a day ahead. Its FAQ also says a permit is good for two years from fee payment, with an inspection needed at least every 12 months so it does not expire.
Can a homeowner pull a plumbing permit?
Yes, in some cases. LADBS's homeowner page says owners of single-family homes may apply for plumbing among other permits, and must complete an Owner-Builder Declaration. Contractors need the C-36 plumbing classification. An owner who pulls a permit takes responsibility for the work, and gas work deserves caution.
Ask yourself honestly if you can do the work to code and pass inspection. A failed inspection leads to rework. For many homeowners, hiring a plumber who pulls the permit is simpler. If you hire, California requires a state contractor license for jobs of $1,000 or more, and you can verify it on the CSLB website.
You may see permit pages for other cities, such as county or city portals elsewhere. They do not apply to a property in the City of Los Angeles, which uses LADBS. A property outside the city limits may use the county or another city, so check which jurisdiction you are in.
How much does a backflow test cost?
Published Los Angeles prices for a residential or irrigation backflow test run about $75 to $150 per assembly, with a wider range of roughly $50 to $250. LADWP's Rule 16-D requires annual testing of required assemblies by a tester licensed by Los Angeles County. Repairs and parts are billed on top.
Cost tends to rise with reduced pressure assemblies, locked gates, buried devices, travel and after-hours calls. See the page on backflow testing services for who may test, what a failed test means and how to book one.
Common questions
How long does a plumbing inspection take?
A plumber's visual inspection of a house often takes one to a few hours, depending on size and findings. A sewer camera run usually takes under an hour once access is open. A permit inspection from the city is a short visit at a stage in the job. Ask each provider how long they expect to be on site.
What should I ask before I hire someone for a plumbing inspection?
Ask what the price covers, whether you receive a written report and video, whether the fee is credited against repairs, how they access the sewer line and whether they check pressure and the water heater. Get the scope in writing. For work of $1,000 or more, check the contractor's state license on the CSLB website.
Does someone need to be at the property?
Plan to be there at the start or have someone who can give access to every room, the garage, the water heater, the meter and any cleanouts. Someone who knows the house helps the inspector find shutoffs. For a permit inspection, an adult needs to give the inspector access, and the contractor often attends.
How much is a sewer camera inspection before buying a house?
Published Los Angeles prices for a pre-purchase sewer scope run about $250 to $500, and one inspector lists a $275 add-on rate when booked with a home inspection. The scope shows cracks, roots and bellies in the line before you commit. Repairs found are quoted separately, and sewer repairs can be costly, so many buyers consider it worthwhile.
How long is a plumbing permit good for?
LADBS's FAQ says a permit is valid for two years from fee payment, and you must call for an inspection at least every 12 months or it can expire. Confirm the current rule with LADBS, since details can change, and ask your plumber to schedule inspections as the work reaches each stage.
