What an inspection looks at and what the report should contain
B&P 7195 defines a home inspection as a non-invasive physical examination, done for a fee in connection with a transfer, of the mechanical, electrical and plumbing systems or the structural and essential components of a dwelling of one to four units, to identify material defects. A material defect is one that significantly affects value, desirability, habitability or safety.
Ask for a written report that says what was looked at, what couldn't be reached and what repair, if any, it recommends and why. Get it before you request a single quote.
What a foundation inspection costs in California: estimates, not quotes
Our estimate for a foundation inspection is $400 to $860 per inspection. It's a model and not a quote, adjusted by the California civil engineer wage ratio, and it doesn't rest on a counted California company price.
Estimated range, not a quote: $400 to $860 per inspection. Built from 2 national published ranges, adjusted by the California civil engineer wage ratio (1.15). Two California foundation companies publish prices (Quartz Construction in San Jose, a range table; Avalon Structural near San Jose, inspection fees); that is too few to anchor a California range, so no company price moves the estimate. Basis: no state company sample (no counted California company price for this job), national estimate only.
Estimated range. Built from national published ranges (2 sources), adjusted by California's civil engineer wage ratio to the US (1.15, BLS May 2025). Not a quote. Only two of the 18 California foundation companies we looked at publish a price we could count, so no company price anchors the estimates. We have no counted California company price for this job, so the range is our national estimate alone. Full method. Prices as of Oct 23, 2026.
Who may inspect, and what California doesn't say
The sources we have don't say whether California licenses home inspectors or what credential an inspector of a foundation must hold, so ask the person for the license or registration they work under and check it with the issuing body. If the inspector is a contractor, check that license on CSLB's Check a License page.
Engineers enter the picture when soil is the question: state law requires a preliminary soil report by a state-registered civil engineer for subdivisions, and a liquefaction zone is where the stability of foundation soils must be investigated. Whether your single-house repair needs the same is for your building department to answer.
Why the report writer should have nothing to install
The company that inspects a foundation often sells the repair, so the report writer should be someone with nothing to install.
Ask any free inspector who writes the report, whether the firm does the repair, and whether anything is owed if the answer is that nothing needs doing.
Inspections and disclosures when you buy
A buyer receives the seller's Natural Hazard Disclosure Statement, which says whether the lot is in a FEMA flood area, a fault zone or a liquefaction or landslide zone. For a one-to-four-unit light-frame house built before 1960, the seller must also deliver the Homeowner's Guide to Earthquake Safety and complete the earthquake hazards disclosure, and a seller with a water heater must certify that it is braced. Read those first, then decide what an inspector should look at.
Foundation signs that can't wait for an appointment
- A wall is moving, leaning or bulging now.
- A floor dropped or a door jammed overnight.
- Water is entering near the electrical panel or outlets, so stay out of it.
- A hairline crack that looks the same as it did months ago.
- A damp spot after a storm that dries within a day.
Before you book an inspection
- Take dated photos of each crack with a coin or ruler for scale.
- Pencil a mark at each end of every crack and write the date beside it.
- Ask any company offering a free inspection who writes the report and whether it also sells the repair.
Permits: the inspection and the repair after it
None of the sources we have list an inspection as permit work. The repair that follows is different, because the state code asks for a permit before a building is altered or repaired, so the office for your address decides.
Ask for the contractor's license number and check it with your state licensing agency before you sign anything.
Questions people ask
Does California require an engineer for a foundation inspection?
The sources we have don't say whether an ordinary foundation repair needs an engineer in California. For a structural question, a written assessment from someone who will not do the repair keeps the diagnosis separate from the sale.
What is a home inspection under California law?
B&P 7195 limits the term to a non-invasive physical examination of a one-to-four-unit dwelling's systems or structural and essential components, done in connection with a transfer, to identify material defects. A material defect significantly affects value, desirability, habitability or safety.
What does a foundation inspection run in California?
Our estimate is $400 to $860 per inspection, adjusted by California's civil engineer wage ratio, and it rests on no counted California company price. Ask what the visit fee is and whether it is credited to a repair.
Can you trust a free inspection offered by a repair company?
The company that inspects often sells the fix, so we recommend a second, independent read. Ask who writes the report and whether the firm does the repair.
What does a California seller have to disclose about the ground?
The Natural Hazard Disclosure Statement covers FEMA flood areas, dam-failure inundation areas, fire hazard zones, earthquake fault zones and seismic hazard zones. The earthquake hazards disclosure and the Homeowner's Guide apply to pre-1960 light-frame homes.
