Modular vs. Manufactured Homes in Hemet, CA

11/9/2026

If you're looking at factory-built homes in Hemet or the San Jacinto Valley, you'll hear two words used almost interchangeably: modular and manufactured. They are not the same thing in California. Each is built in a factory, but they are built and regulated under different rules, and that can affect how your home is titled, inspected and installed. Here's what Hemet and Riverside County buyers should know, from Williams Manufactured Home Solutions, a family business that has been helping people find homes since 1959.

Both are built indoors, under different rulebooks

A manufactured home is built in a plant to a single federal standard, the HUD Code. HUD's Office of Manufactured Housing Programs administers that code under the National Manufactured Housing Construction and Safety Standards Act of 1974, and a certification label goes on each section of a compliant home.

In California, the category that matches what many people call a modular home is factory-built housing. The California Department of Housing and Community Development (HCD) describes factory-built housing as "a factory-constructed version of a site-built residential building" that is built and then transported to its permanent location. HCD regulates the manufacturing of factory-built housing and building components made for sale in California. An HCD information bulletin says new factory-built housing plans submitted on or after January 1, 2023 must be designed and built to the 2022 California Building Standards Code (Title 24) and HCD regulations, and that factory-built housing does not include a manufactured home or mobilehome. So the short version: manufactured homes follow the federal HUD Code, while factory-built homes follow California's own building code.

How the home is titled and registered

This is one of the biggest practical differences for California buyers. HCD's Registration and Titling program issues registration and title documents for new and resold manufactured homes and handles renewals, tax clearances and title transfers.

That changes when a manufactured home is permanently installed. According to HCD, once a manufactured home is installed on a foundation system, it is no longer registered by HCD, and the department has a separate process for canceling the registration. In other words, how and where you install a manufactured home affects how it is documented, which may matter to lenders and insurers. A factory-built (modular) home is built as a version of a site-built building, so ask your dealer and your local building department how it will be permitted and recorded for your property.

Foundations, permits and your lot

Whether you're placing a home on your own lot in Hemet or in a community, the installation plan matters as much as the floor plan. Before you choose a home type, check with the City of Hemet or Riverside County about what your property allows, and ask your dealer who handles permits. Williams MHS says that from permitting to delivery and setup, the owner handles the details for his buyers.

Financing and appraisal

The home type and how it's installed can affect which loans are available and how a home is appraised. Williams MHS says it works with several lenders who specialize in manufactured home financing, including FHA, VA and chattel loans. Because each lender has its own rules for each home type, talk to lenders before you commit to a specific home. You can start on the Williams financing page.

Which is right for you?

There's no single answer. A few questions to settle first:

• Will the home go on land you own, on a lot you're buying, or in a community?
• Do you want a permanent foundation, and does your lot allow it?
• Which loan types are you likely to use, and what do those lenders require?
• What size and layout do you need, and what's your budget?

Once you know those, comparing specific floor plans gets much easier.
