Modular Homes

Modular and prefab homes in San Diego County. Built to the same code as site-built.

Modular homes are factory-built to California state building code, the same code that governs site-built construction, and they sit on a permanent stem-wall or basement foundation. There is no steel chassis. They are legally and structurally equivalent to a site-built home for financing and zoning purposes. That is the key distinction from a HUD-code manufactured home, and it matters for what lenders will finance and where local zoning will allow placement.

What buyers ask about Modular Homes

What is the difference between modular and manufactured?

A manufactured home is built to the federal HUD code and has a permanent steel chassis. It is titled through the California Department of Housing and Community Development, similar to a vehicle, unless it goes through the real-property conversion process. A modular home is built in a factory but to California Title 24 state building code, the same code that applies to houses built on-site. It has no steel chassis, sits on a permanent foundation, and is treated as real property from the start. Lenders and local zoning generally treat modular homes identically to site-built homes.

Are modular homes cheaper than site-built?

Usually yes, for the structure itself, because factory conditions reduce waste and speed up assembly. The savings on the unit can run 10 to 20 percent versus comparable site-built construction. Site work, foundation, utility connections, and permits cost roughly the same as a site-built home on the same lot. Total savings depend heavily on the site conditions.

Can a modular home be customized?

Yes, most modular builders offer significant customization: floor plans, exterior finishes, rooflines, window placement, kitchen and bath selections. The degree of customization varies by builder and price point. Some modular builders offer a fully custom design process; others work from a catalog of floor plans with finish selections. We connect you with builders who match your scope and budget.

Will a modular home appraise at the same value as site-built?

A modular home on a permanent foundation should appraise comparably to site-built homes of similar size and quality in the same area. The key is that the home must be on a permanent foundation and titled as real property. Appraiser familiarity varies, and in rural areas with few comparables you may encounter some friction, but the legal basis for equal treatment is solid.

Does a modular home need the same permits as a site-built home?

Yes. A modular home still requires a local building permit, a grading or site permit if there is significant earthwork, and inspections by the local building department at key stages. The factory portion of construction is inspected by a state-approved third-party inspection agency rather than your local inspector, but local inspections still happen at the foundation and final stages.

We had five acres of family land sitting empty for years. Land & Home SD walked us through every step: the dealer search, HCD permits, foundation requirements, and Section 6506 compliance. We closed on a three-bedroom home in four months. Never could have navigated that alone.

Land and Home Placement Ramona

We wanted to add a unit for my mother-in-law without a full construction project. Land & Home connected us with a dealer who had the right floor plan, explained the AB 1033 rules, and confirmed the permit path before we spent a dollar. The ADU is on the foundation and she moved in right on schedule.

Manufactured Home ADU Vista

I'd been renting for three years after my husband passed. The consultant helped me understand space-rent leases versus land-owned parks, and found me a well-maintained 55-plus community two miles from my daughter. I own my home now. That matters more than I can say.
