Buying a Manufactured Home on Its Own Land in Snohomish or King County (2026)

Short answer: You can buy a manufactured home that sits on its own land in Snohomish or King County the same way you’d buy a site-built house, but only if the home’s vehicle-style title has been eliminated and the home is legally part of the land. If the title still exists, the home is treated as personal property under the vehicle title law, which changes how it’s transferred and financed. Find out which one you’re dealing with before you write an offer, then check permits for any alterations and the condition of the installation.

This is general information, not legal or tax advice. A title company, your lender and a Washington real estate attorney can tell you how the rules apply to a particular property.

Title first: is the home part of the land?

Washington handles this in chapter 65.20 RCW. The key rule is in RCW 65.20.030: for a manufactured home sold on or after March 1, 1990, the home is real property only if its title has been eliminated under that chapter. Otherwise, ownership is determined under chapter 46.12 RCW, the same law used for vehicle titles.

• Title eliminated. The Department of Licensing records the approved application with the county auditor, and the title is deemed eliminated on the recording date (RCW 65.20.050). From then on, the home is conveyed by deed, lease or real estate contract and only together with the land (RCW 65.20.060). A loan is secured as part of the real property, through a mortgage, deed of trust or real estate contract.
• Title still active. The home is personal property for ownership and security purposes. A lender’s interest is perfected on the title under chapter 46.12 RCW, and the home is transferred like a titled vehicle even though it’s sitting on land you’re buying.

A few definitions in RCW 65.20.020 matter here. "Affixed" means installed according to the state’s installation standards. "Owner" of the land includes someone holding a lease of 35 years or more. And "manufactured home" means a home built under the federal HUD code, not a modular home. The section was last amended in 2025, effective October 15, 2025.

Your preliminary title commitment is the place to see whether the elimination was recorded. If the seller is still working on it, the application needs an affidavit, the title or manufacturer’s statement of origin with any lender’s release, a local government certification that the home is affixed, and payment of fees and taxes due (RCW 65.20.040). A lender doesn’t have to consent unless its contract requires it, and it may charge a reasonable fee for processing the request (RCW 65.20.060). Build that time into your closing process.

Titled vs. title eliminated

Based on: RCW 65.20.020, 65.20.030, 65.20.040, 65.20.050, 65.20.060 and 65.20.070, Washington State Legislature.

Alterations, permits and the seller disclosure

Manufactured homes have their own permit rules, separate from the city or county building permit for a site-built house. Under WAC 296-150M-0300, a permit from the Department of Labor and Industries (L&I) must be bought before altering a manufactured home, and the person doing the work buys it. A homeowner can’t buy a permit for a contractor. Alterations made without approval and an alteration insignia bring in the sale rules in WAC 296-150M-0049 (WAC 296-150M-0310). Alterations must meet the federal standards in 24 CFR Part 3280, and WAC 296-150M-0306 also requires carbon monoxide alarms under RCW 19.27.530.

Under WAC 296-150M-0049, before selling an installed manufactured home, the homeowner must:

• Give the buyer a completed seller disclosure statement (Form 17) under chapter 64.06 RCW, unless the seller is exempt or the buyer waives it.
• Have all the L&I insignia the chapter requires, or at least the insignia for alterations made during their own ownership, and list in the disclosure all alterations known to have been made by previous owners or occupants.

The same rule allows a conditional sale, where the purchase depends on the seller meeting conditions the buyer sets, such as getting alterations approved. The homeowner, the buyer or the lender can ask L&I to inspect. If L&I decides an alteration may be a hazard, it notifies the parties in writing within 30 days of the inspection.

Form 17’s Section 8 asks three questions when the property includes a manufactured or mobile home: did you make alterations (8A), did any previous owner (8B), and were permits or variances obtained (8C). A "yes" with no permit is the same kind of issue we cover in our guide to unpermitted work. RCW 64.06.020 currently has two versions on the Legislature’s site: one marked effective until January 1, 2027, and one effective January 1, 2027. The questions quoted here appear in both. If your sale runs across the new year, check which form is being used.

Installation counts too. Under WAC 296-150I-0200, a certified manufactured home installer must be on site for each phase of an installation. Ask the seller for installation paperwork along with the permits.

What to check before your inspection deadline

Data from: chapter 65.20 RCW, RCW 43.22.432, RCW 19.27.530, RCW 64.06.020 (Form 17) and WAC 296-150M and 296-150I, Washington State Legislature.

The rest of the purchase

A manufactured home on its own lot often comes with the same land questions as any rural property: septic systems, private wells, access and boundaries. A general home inspector will look at the home itself; read what a standard home inspection covers and ask whether the inspector is comfortable with manufactured homes, including the installation and the skirting. Schedule the title and permit questions inside your inspection contingency period so you still have options if the answers aren’t what you expected.

Financing depends on the title status and your lender’s rules, so talk to your lender as soon as you know whether the title has been eliminated. Questions about property tax treatment belong with the county assessor or a CPA.

FAQ

Is a manufactured home real property or personal property in Washington?

It depends on the title. Under RCW 65.20.030, a manufactured home sold on or after March 1, 1990 is real property only if its title has been eliminated under chapter 65.20 RCW. If the home still has a title, ownership is handled under chapter 46.12 RCW, the vehicle title law, and a loan on it is a personal property security interest.

How do I find out whether the title was eliminated?

Ask the seller and the title company early. When the Department of Licensing approves an application to eliminate the title, it has the application recorded with the county auditor where the land is, and the title is deemed eliminated on the recording date (RCW 65.20.050). That recorded document should show up in the title search.

What does it take to eliminate a manufactured home title?

Under RCW 65.20.040, the homeowner applies to the Department of Licensing with an affidavit (owners, legal description, model year, make, size, VIN, secured parties, and a statement that the owner owns the land), the title or manufacturer’s statement of origin with any lender releasing its interest, a local government certification that the home is affixed to the land, and payment of fees and taxes due. A lender doesn’t have to consent unless its contract says so, and it may charge a reasonable fee.

Does it matter if a previous owner remodeled the home?

Yes. Alterations to a manufactured home generally need an L&I permit and an alteration insignia (WAC 296-150M-0300 and -0310). Before selling, the owner must have the required insignia for alterations made during their ownership and disclose known alterations by earlier owners (WAC 296-150M-0049). Form 17 asks about this in Section 8. The buyer or lender can also request an L&I inspection.

Is a modular home the same as a manufactured home?

Not under chapter 65.20 RCW. Its definition of manufactured home is a home built under the federal HUD code and specifically excludes modular homes (RCW 65.20.020). Modular homes are built to the state building code instead, so ask the seller and your agent which kind you’re looking at.
