Before a manufactured home can be appraised like a house, the report has to settle what is being valued. If the home has been affixed to land it owns, or holds on a qualifying lease, through the steps in California Health and Safety Code section 18551, it is real property and can be valued with its land from comparable sales. If it is still registered with the state as a movable home, it is personal property, often sitting on rented space, and that is a different question with different evidence.
The pillar guide to condo and manufactured home appraisals covers the condo side, and the condominiums and manufactured homes hub lists the series.
Real property and personal property, in plain words
Real property is land and whatever is permanently attached to it: a house, a garage, a foundation. Personal property is movable property: furniture, a car, and in California a manufactured home that has not been permanently attached. The difference is legal and recorded, so the appraiser asks for papers before measuring a room.
The status changes the market. A home that is real property sells with its land; a home that is personal property on rented space sells without land, subject to the space terms, to a different pool of buyers.
How a manufactured home becomes real property in California
Section 18551 lets a manufactured home be installed on a foundation system in one of two ways: as a fixture or improvement to the real property, or as a chattel, which is movable personal property. To become real property, the statute requires a sequence:
- The owner or a licensed contractor obtains a building permit from the local enforcement agency, showing that the home's owner owns or is buying the land, or holds a transferable lease of the kind the statute describes.
- The permit file includes foundation plans and the manufacturer's installation instructions, or plans signed by a California-licensed architect or engineer, plus evidence that the home carries no liens or that any lienholder consents.
- After the certificate of occupancy issues, the enforcement agency records a document with the county recorder stating that the home has been affixed to that land by installation on a foundation system. The recorded document gives notice to anyone later dealing with the property.
- The certificate of title and registration are surrendered to the Department of Housing and Community Development (HCD) under its rules for canceling the registration.
Once installed this way, the statute says, the home is "deemed a fixture and a real property improvement," and it cannot be removed without the consent of everyone holding an interest in the land. Revenue and Taxation Code section 5801 adds that a home that has become real property under section 18551 is taxed as all other real property is taxed.
The appraiser does not decide any of this and gives no opinion on title. The recorded document, the canceled registration and the title report show the status; a title company or attorney confirms it. Nothing here is legal advice.
What the report records once the status is known
Two federal marks identify the home. The data plate is a paper document inside the home that lists, among other things, the manufacturer's name and trade or model number and the equipment installed at the factory. The certification label, sometimes called a HUD seal or tag, is a metal plate on the exterior of each section of the home. Either one is the evidence that the home was built to the federal Manufactured Home Construction and Safety Standards. Fannie Mae requires the appraiser to provide photos of the data plate or the certification labels on an existing home. If neither survives, the lender must obtain a label verification letter or a duplicate data plate from the Institute for Building Technology and Safety instead.
The inspection documents:
- Whether the home sits on a permanent foundation system, and how it is attached.
- Whether the towing hitch, wheels and axles have been removed.
- Whether it is permanently connected to a septic tank or sewer and to other utilities.
- What additions or modifications have been made, such as decks, rooms or porches, and whether permits exist for them.
- Living area, measured under the same ANSI standard Fannie Mae applies to other single-family dwellings, including manufactured homes.
What a lender looks for
For loans sold to Fannie Mae, the home must be a one-unit dwelling legally classified as real property. It must sit on a permanent foundation system, be built to the federal standards, never have been installed or occupied at another site except as a new unit, and meet minimum width and finished-area requirements. Those are eligibility rules, and the lender applies them.
Fannie Mae requires a market-based valuation, at least two comparable sales that are manufactured homes, and a detailed and supported cost approach. The value must be based solely on the real property and cannot include any non-realty items.
For reports submitted to Fannie Mae and Freddie Mac on or after November 2, 2026, when UAD 3.6 became mandatory, the Form 1004C is retired; Freddie Mac lists it among the legacy forms replaced by the redesigned Uniform Residential Appraisal Report. Freddie Mac says the purpose of the URAR has not changed, and its condition and quality ratings apply to manufactured homes too. The explainer on the 1073 and the move to one report covers the change for condos.
A home on rented space in a La Verne park
La Verne has mobile home parks whose space rents the city reviews under Municipal Code Chapter 9.16, its Mobile Home Rent Review process. A home in one of those parks usually sits on space the owner rents, not land the owner holds. It is never valued as if it owned its land, or compared with a detached house on its own lot. Its market is other homes in similar parks, read with the space terms and park rules.
Not every manufactured-home type is a residential real property assignment. A home that is personal property on rented space raises different questions, and assignments in the parks are considered case by case, with the report stating the ownership, space terms and condition it relied on. Nothing here is legal advice on park rent rules. The La Verne area page describes the city's other markets.
A home on its own lot
A manufactured home that is real property on owned land, in Chino, Pomona or elsewhere in the two counties, is appraised with its site and compared with other manufactured homes on owned land. Site-built houses nearby may show what the land is worth, but they are not substitutes for the home.
What to gather first
- Where the data plate is, and whether the exterior labels are still attached.
- Any HCD title or registration papers, and the recorded foundation document if the home was affixed.
- Building permits and the certificate of occupancy for the installation, and permits for any additions or porches.
- In a park, the space lease and the park's rules.
A lender orders the appraisal for a loan. Private assignments, such as an estate or a trust, can be ordered directly once the property status is clear. Fees are set by the scope of the assignment and quoted before work begins, and they do not depend on the value. See residential appraisals for lending and refinance, or call (909) 324-6122.

Frequently asked questions
Is a manufactured home real property or personal property in California?
It starts as personal property registered with HCD. It becomes real property when it is installed on a foundation system as a fixture under Health and Safety Code section 18551: a building permit, a certificate of occupancy, a document recorded with the county recorder, and the HCD title and registration surrendered and canceled. A title company or attorney confirms the status.
Does the appraiser decide whether my manufactured home is real property?
No. The appraiser gives no opinion on title. The appraiser asks for the recorded document and registration papers, records the data plate, labels and foundation, and reports the status the documents show.
What are the HUD data plate and certification label?
The data plate is a paper document inside the home listing, among other things, the manufacturer's name, the trade or model number and the factory-installed equipment. The certification label, sometimes called a HUD seal or tag, is a metal plate on the exterior of each section. Either shows the home was built to the federal standards, and Fannie Mae requires photos of one or the other.
Can a manufactured home in a La Verne park be valued like a house?
No. A home on rented park space does not own its land, so it is never valued as if it did or compared with a detached house on its own lot. Assignments in the parks are considered case by case, and the report states the ownership, space terms and condition it relied on.
