An insurance figure for a house and an appraisal of that house answer two different questions. Replacement cost, the amount it costs to replace lost or damaged property with new property of like kind and quality in the local market, is what a homeowners policy's dwelling limit is meant to track, and insurers and their broker-agents estimate it with their own formulas. Market value, the most probable price the whole property would bring in a competitive and open market, land included, is what a state-licensed or certified appraiser develops in an appraisal. One is a cost to rebuild the structure; the other is a price for the property, and neither number tells you the other.
What do people mean by an "insurance appraisal" for a home?
The phrase covers three different things.
- A replacement cost estimate. The figure an insurer or broker-agent uses for the dwelling limit. The California Department of Insurance residential insurance guide says each insurance company has its own formula, so different insurers may suggest or require different limits. It is not an appraisal.
- The appraisal clause in a policy. California's standard form fire policy, in Insurance Code section 2071, uses "appraisal" for a claims process: when the insured and the company fail to agree on the actual cash value or the amount of a loss, each selects a competent and disinterested appraiser, and the two select an umpire. It values a loss, not the market value of the house.
- An appraisal of market value. An independent opinion of market value as of an effective date, the date the opinion applies to, developed and reported under the Uniform Standards of Professional Appraisal Practice (USPAP). This is the kind of report the services on this site describe.
An insurance replacement cost estimate is not among the services on this site. How much dwelling coverage to carry is a question for your insurer, agent or broker; nothing here is insurance advice.

The Department of Insurance guide says the dwelling limit should be the amount it would cost to replace your home, and this may have nothing to do with the purchase price or the current market value, because homeowners insurance does not generally cover the land the dwelling sits on. It tells owners to consider the cost of labor and materials to rebuild, not fluctuations in the real estate market.
Market value, as the 2010 Interagency Appraisal and Evaluation Guidelines define it for lending, is the most probable price a property should bring in a competitive and open market under all conditions requisite to a fair sale. Nothing in it is about the cost of building; what is market value walks through each condition.
Why the two numbers part ways on real houses
Either can be the larger number. The reasons show up on houses around Claremont and Rancho Cucamonga.
- Location and land. Market value carries the lot, the view, the street and the buyer pool; a replacement cost estimate generally does not carry the land at all. A Claraboya or Padua Hills house that sells on view, grade and access, or an Alta Loma or Etiwanda horse-keeping lot, has a site buyers weigh heavily and a rebuild figure ignores.
- Age and condition. Market value reflects the house as it stands. Replacement cost is about rebuilding with new materials of like kind and quality.
- Original detail. A pre-1940 Craftsman or Spanish Colonial Revival house near the Village and the Colleges may carry millwork, plaster and raised foundations that cost a great deal to recreate. Buyers may or may not pay for that detail in proportion to its cost.
- Building codes. The Department of Insurance notes that cities and counties change building codes, and that some policies do not include building code upgrade coverage. A rebuild is built to current code; a sale price reflects the house as it stands.
The Claremont area page and the Rancho Cucamonga area page describe these pockets. Appraised value vs. market value covers what the appraisal's number is.
Does an appraisal ever estimate cost?
Sometimes, but as a step toward market value, not as an insurance figure. The Fannie Mae Selling Guide on the cost and income approaches describes the cost approach as measuring value as a cost of production, on the assumption that a buyer would consider building a substitute house with the same use. Fannie Mae does not require it except for manufactured homes, USPAP requires any approach necessary for credible results, and the Guide says appraisals that rely solely on the cost approach as an indicator of market value are not acceptable. The page sends UAD 3.6 lenders to a separate supplement.
So when a cost approach appears in an appraisal, its intended use, what the report will be used for, is still the opinion of market value. It is not written to set a policy limit. The Interagency Guidelines add that value opinions such as "value in use" or a special value to a specific property user may not be used as market value for federally related transactions.
What does California require of insurers on replacement cost?
The Department of Insurance guide says that if an insurer or broker-agent communicates a replacement cost estimate in connection with an application or renewal of a replacement cost policy, a copy must be provided to the person who agrees to buy coverage. Insurance Code section 10103.4 sets an insurer's duty to provide a rebuild estimate at renewal, on the schedule and with the exceptions the section states, and says it does not change the policyholder's duty to select coverage limits.
Questions about those estimates, the policy wording or a claim go to the insurer, the agent or broker, or the Department of Insurance. Under section 10103.4 the policyholder still selects coverage limits; an appraiser does not.
Which other numbers are not appraisals?
An automated estimate from a portal is not an appraisal; it is a statistical estimate from records and nearby sales. An agent's comparative market analysis, or CMA, a licensed agent's opinion of a likely list or sale price, is not an appraisal. The county assessment is not an appraisal; it is taxable value under California's assessment rules. A cash offer is not an appraisal; it is one buyer's price on stated terms. And an insurer's replacement cost estimate is not an appraisal either. The four different numbers guide compares the main ones, the fair market value vs. market value article compares the tax and lending definitions, and the whole cluster is in the value types knowledge center.
If you need market value documented for a lender, an estate, a trust, a divorce or a tax appeal, start with appraisal vs. estimate or call (909) 324-6122. Fees are set by the scope of the assignment, quoted before work begins, and do not depend on the value.

Frequently asked questions
Is an insurance replacement cost estimate the same as an appraisal?
No. A replacement cost estimate is the insurer's or broker-agent's figure for the cost of labor and materials to rebuild the dwelling with like kind and quality, made with the company's own formula. An appraisal is a state-licensed or certified appraiser's independent opinion of the market value of the whole property, land included, as of a stated date.
Why is my dwelling coverage different from what my house would sell for?
Because they measure different things. The California Department of Insurance says the dwelling limit should be the cost to replace the home, which may have nothing to do with the purchase price or current market value, since homeowners insurance does not generally cover the land. Market value includes the land, location and condition. Coverage questions belong with your insurer, agent or broker.
Who prepares a replacement cost estimate for homeowners insurance in California?
The insurer or the broker-agent, using the insurance company's formula. The Department of Insurance says that when an estimate is communicated in connection with an application or renewal of a replacement cost policy, a copy must be provided to the person who buys the coverage, and Insurance Code section 10103.4 sets renewal estimate duties for insurers.
Does a market value appraisal include a cost approach I can give my insurer?
An appraisal may include a cost approach when it is needed for credible results, but its intended use is still the opinion of market value. Fannie Mae says appraisals that rely solely on the cost approach as an indicator of market value are not acceptable. A cost approach in an appraisal is not written to set a policy limit, and the insurer applies its own formula.
What is the appraisal clause in a California property insurance policy?
Insurance Code section 2071 sets out a claims process called appraisal: when the insured and the company fail to agree on the actual cash value or the amount of a loss, each selects a competent and disinterested appraiser and the two select an umpire. It values a loss under the policy, not the market value of the house. Nothing here is legal or insurance advice.
