A home inspection and an appraisal look at the same house for different reasons. A home inspection is a condition report produced by a home inspector: it tests the systems and structure and contains no opinion of value. An appraisal is an independent opinion of market value as of a stated date, developed from closed comparable sales under the Uniform Standards of Professional Appraisal Practice (USPAP), the national standards for appraisal. The appraiser observes condition because it affects value, but does not test systems.
The rest of this article sets the two side by side, explains the one place they overlap, and shows how they divide the work on the older houses common in Claremont and Pomona.
What does a home inspector do?
A home inspector evaluates how the house works. The inspection runs the faucets, opens the electrical panel, checks outlets, runs the heating and cooling, looks at the roof covering and flashing, enters the attic and crawl space where they can, and reports defects and safety concerns. The result is a report of findings, often with photographs and recommendations to have a licensed trade look further.
The inspection does not say what the house is worth. It answers a different question: what is wrong with it, or likely to need attention soon.
What does an appraiser do?
An appraiser develops an opinion of market value. At the house, that means measuring the exterior to calculate gross living area, the finished space above grade, photographing each room, and recording quality, updating and visible condition. Away from the house, it means researching closed sales that buyers would have compared with this one and adjusting each sale for differences in size, lot, condition, location and features.
The appraiser notes that a water heater is old or a roof is near the end of its life, because buyers pay less for a house that needs those replaced. The appraiser does not turn on the furnace to see whether it works. The how it works page describes the full sequence, and what happens on appraisal inspection day in Claremont covers the visit itself.
How do the two compare?
Home inspection | Appraisal | |
|---|---|---|
Who does it | A home inspector | A licensed or certified appraiser |
What it produces | A condition report on systems and structure | An opinion of market value as of a stated date |
What is tested | Plumbing, electrical, heating and cooling, appliances, roof, attic, crawl space | Nothing is tested; condition is observed and recorded |
Standard it follows | The inspector's standards of practice | USPAP |
Who relies on it | The buyer, for repair requests and the decision to proceed | The intended users named in the report, such as a lender, court, trustee or homeowner |
When it is ordered | Usually by the buyer during the contingency period | By a lender for a loan, or directly by a homeowner, attorney, CPA or trustee |
The row that matters most is the one about reliance. Intended users, the people entitled to rely on the report, are named on the face of every appraisal, and the report is written for its intended use, what it will be used for.
Where do they overlap?
The one real overlap is government-insured lending. FHA and VA appraisals add minimum property condition requirements to the value opinion, so the appraiser on those assignments calls out specific items that must be repaired before the loan can close. The items that come up in older housing include peeling paint on pre-1978 homes, unstrapped water heaters, missing handrails at exterior steps, roof condition, exposed wiring, broken windows, inoperative heating, and missing access to the attic or crawl space.
Even there, the appraiser is not performing an inspection. The FHA or VA appraiser identifies visible conditions against a program checklist. A home inspector still tests what the appraiser only looks at, and a buyer on an FHA or VA loan still benefits from a separate inspection.
Why does a buyer usually want both?
Because each answers a question the other cannot.
The inspection tells a buyer what the house needs, which shapes repair requests and whether to proceed at all. The appraisal tells the lender, or the buyer directly, what closed sales support for this house as of a stated date. A house can pass inspection with minor findings and still appraise below the contract price. Another can appraise at the contract price and still carry a failing sewer line that only the inspector's camera finds.
Buyers paying cash sometimes skip the appraisal because no lender requires one. A pre-purchase appraisal fills that gap with an independent opinion of value built from closed sales, written to be reviewed rather than used as a negotiating instrument.
What about Zestimates, CMAs and assessments?
None of them is an appraisal, and none is an inspection. An automated estimate such as a Zestimate or other AVM is a computer model. An agent's CMA, a comparative market analysis, is a pricing opinion prepared to list or buy. The county's assessed value is a tax figure. A cash offer is what one buyer will pay. The differences are laid out on appraisal vs. estimate.
How do the two divide the work on an older Claremont or Pomona house?
Older houses are where the difference between recording and testing shows most clearly. Claremont's older stock includes Victorian, Colonial and Spanish Colonial Revival houses and bungalows, and Pomona's Lincoln Park Historic District is mostly single-family homes built from the 1890s through the 1940s. These are the kinds of items that come up in those files.
- Original wiring. The appraiser records the panel type and any visible knob-and-tube or ungrounded outlets, because buyers price in rewiring. The inspector tests the circuits and flags hazards.
- Raised foundations. The appraiser notes the foundation type and visible condition from the access point, and whether the house has been bolted or braced where that is apparent. The inspector enters the crawl space and reports on posts, piers, moisture and framing.
- Enclosed porches. The appraiser asks whether the enclosure was permitted and decides whether that space counts as gross living area or is treated separately. The inspector checks the framing, the windows and whether the space is safely heated and wired.
- Water heater strapping. The appraiser records whether the water heater is strapped and its approximate age. The inspector checks the strapping, the venting and the pressure relief valve.
In each case the appraiser is asking how the item affects what buyers pay, and the inspector is asking whether it works and whether it is safe. The Pomona area page describes the older neighborhoods where both questions come up most.

Frequently asked questions
Can an appraisal replace a home inspection?
No. An appraisal does not test systems, enter crawl spaces or diagnose defects. It records visible condition because condition affects value.
Can a home inspection replace an appraisal?
No. An inspection contains no opinion of value and is not built from comparable sales.
Which comes first?
Usually the inspection, during the buyer's contingency period, with the lender's appraisal ordered around the same time. A buyer paying cash can order an appraisal directly at any point before closing.
Will the appraiser read my inspection report?
It can be provided, and documented facts in it, such as a replaced roof or a known foundation issue, help the appraiser describe condition accurately. The appraiser still forms an independent opinion from the property and the comparable sales.
Does an FHA or VA appraisal count as an inspection?
No. Those appraisals add minimum property condition items to the value opinion, but they are not a substitute for a home inspection.
