How to Add a Name to a Mobile Home Title in California

To add a name to a mobile home title in California, file the Department of Housing and Community Development’s Multi-Purpose Transfer Form (HCD RT 476.6G) along with the original Certificate of Title, a $35 fee, any lienholder’s written consent, and — for homes on the local property tax roll — a current Tax Clearance Certificate from the county tax collector. The paperwork itself is manageable. The decisions behind it, especially the form of co-ownership and the tax consequences, deserve more attention than the form does.

What to Gather and File

The core document is HCD’s Multi-Purpose Transfer Form (HCD RT 476.6G), available from the HCD website or by mail.¹ Depending on the circumstances of the transfer, you may also need a Statement of Facts (HCD RT 476.6A). Both ask for:

Full legal names and addresses of every current and new owner.
The HCD decal number, printed on a small metal plate attached to the outside of the home, in a format of three letters followed by four numbers.²
Serial numbers for every section of the unit.
The situs address, meaning the physical location where the home sits.

You’ll also need the original Certificate of Title. If it’s lost, apply to HCD for a duplicate before starting the name change.

For mobile homes subject to local property tax (most homes originally sold new on or after July 1, 1980), you must include a Tax Clearance Certificate from the county tax collector where the home is located. It confirms property taxes are current, and HCD will not process the title change without it.³ The certificate is valid for 60 days from the date it’s issued.⁴

The fee is $35 to add, remove, or change a registered owner’s name.⁵ Pay by check or money order to the Department of Housing and Community Development. Don’t send cash. Mail the packet to HCD’s Registration and Titling processing center at the address listed on HCD’s website.⁶ Some HCD offices also accept in-person submissions. Once the application is approved, a new Certificate of Title reflecting the updated ownership will be mailed to you.

Choose How the New Owners Will Hold Title

Adding a name means declaring how the owners hold the property together. That choice controls what happens if one owner dies, whether the survivor has to go through probate, and how the property tax rules treat the transfer.

Joint tenancy with right of survivorship. Each owner has an equal share. When one owner dies, the survivor automatically receives the deceased owner’s interest without probate. This is the common choice for family members who want a simple transfer at death.
Tenants in common. Each owner holds a distinct share that can be unequal. A deceased owner’s share does not pass automatically to the co-owner; it goes to whoever the deceased named in a will or, absent a will, through California’s intestacy rules. This works better when co-owners want independent control of their respective shares.
Community property with right of survivorship. Available only to married couples and registered domestic partners. Like joint tenancy, the surviving spouse automatically inherits. Its distinctive advantage is a full stepped-up tax basis at death for both halves of the property, which can reduce capital gains taxes if the survivor later sells.

Consider a Transfer-on-Death Beneficiary Instead

If your real goal is inheritance planning rather than shared ownership during your lifetime, HCD allows you to name a transfer-on-death beneficiary who receives the home after your death without ever appearing on the title while you’re alive.¹ A TOD beneficiary has no ownership rights until the owner dies, which sidesteps gift tax exposure, property tax reassessment, and complications with government benefits. Adding someone to the title now and using a TOD designation are two different tools for two different situations.

If There’s a Loan on the Home

Any lienholder recorded on the Certificate of Title must give written authorization before HCD will process the name change. Contact your lender, explain that you want to add a co-owner, and ask what they require. Some lenders will issue a simple written consent; others run a credit check on the new owner or ask for a formal application. HCD’s transfer forms include a section for lienholder signatures, and an incomplete form will be rejected. Don’t skip this step.

Due-on-Sale Protections

Federal law limits when a lender can call a loan due after a title change. The Garn-St. Germain Act applies to loans secured by residential manufactured homes and prohibits a lender from calling the loan due when you add a spouse or child to the title.⁷ The same protection covers transfers into a living trust where you remain the beneficiary and transfers resulting from divorce or legal separation.

If you’re adding anyone else, Garn-St. Germain doesn’t apply, and the lender could technically exercise the due-on-sale clause. In practice, most lenders won’t call a loan due as long as payments continue, but get that in writing before you file.⁷

Whether the Transfer Triggers a Property Tax Reassessment

Mobile homes originally sold new on or after July 1, 1980, are subject to local property taxes.³ Whether adding a co-owner counts as a reassessable “change in ownership” depends on the form of co-ownership and the relationship between the owners.

California law excludes several transfers from that definition. Creating a joint tenancy where you (the original owner) remain one of the joint tenants is generally not treated as a change in ownership. Transfers between spouses or registered domestic partners are also excluded, as are transfers into a revocable trust where the transferor remains the beneficiary.⁸

The trouble usually shows up when someone adds a non-spouse as a tenant in common. That transfer creates a separate ownership interest and can trigger reassessment of the transferred portion, raising the annual tax bill. If you’re adding an unrelated person, the distinction between joint tenancy and tenancy in common is worth understanding before you fill out the form.

Homes purchased new before July 1, 1980, are subject to an annual vehicle license fee rather than property tax, unless the owner voluntarily converted to the property tax system. For those homes, the reassessment question doesn’t apply.³

Federal Gift Tax

Adding a non-spouse to the title without receiving payment in return can be treated by the IRS as a taxable gift. For 2026, the annual gift tax exclusion is $19,000 per recipient.⁹ If the value of the interest you transfer exceeds $19,000, you’ll need to file IRS Form 709. Married couples who elect gift-splitting can combine their exclusions, allowing up to $38,000 to one recipient without a filing requirement.

Filing the return doesn’t necessarily mean you’ll owe tax. It reduces your lifetime gift and estate tax exemption, which most people never exhaust. Failing to file when required, though, can create penalties later. Transfers between spouses are completely exempt from gift tax regardless of value.

Capital Gains: The Consequence Most People Miss

When you add someone to your title as a gift, the new co-owner inherits your original cost basis in the property, not the home’s current fair market value.¹⁰ This is called a carryover basis. If you bought the home for $40,000 and it’s now worth $120,000, the new co-owner’s basis for their share is calculated from your $40,000 purchase price.

Compare that to inheritance. An heir who inherits property receives a stepped-up basis equal to the fair market value on the date of death, which essentially erases the accumulated gain. If the same home is worth $120,000 when you die, the heir’s basis would be $120,000. Selling at that price means zero capital gains tax, rather than tax on $80,000 of gain.

Adding someone to the title now, rather than letting them inherit through joint tenancy survivorship or a TOD designation, can create a larger capital gains bill when they eventually sell.¹⁰ For a modest mobile home the gap may be small, but it should factor into the decision.

Effect on SSI and Medi-Cal

Adding someone to your title, or being added to someone else’s, can affect eligibility for means-tested programs.

SSI

SSI resource limits in 2026 are $2,000 for individuals and $3,000 for married couples.¹¹ Your primary home is normally excluded from countable resources regardless of value. Giving away a partial interest by adding a co-owner, however, could be treated as disposing of a resource. If you receive SSI, talk to your local SSA office before making any title changes.

Medi-Cal Long-Term Care

Medi-Cal examines recent asset transfers when someone applies for nursing home or long-term care coverage. California has been phasing in a look-back period under recent legislation, and the length of that look-back varies by the month you apply in 2026.¹² Gifting a partial interest in your mobile home during that window can produce a penalty period during which Medi-Cal won’t cover long-term care costs. If Medi-Cal coverage may be needed by you or the person you’re adding, an elder law attorney’s advice before the transfer is well worth the cost.
