Manufactured vs. Modular vs. Mobile Homes

The short version: manufactured homes are built to the federal HUD Code on a steel chassis; modular homes are built to the same local (IRC) codes as site-built houses and set on a permanent foundation; and “mobile home” technically means a factory-built home made before June 15, 1976. All three are built in a factory — the differences are in code, foundation, and financing.

All new homes we sell are manufactured or modular — built to current HUD or IRC codes.

Manufactured Homes (HUD Code)

Manufactured homes are built entirely in a factory to the federal HUD Code and transported to your site on a permanent steel chassis. They come as single wides, double wides, and triple wides, and they’re the most affordable path to new home ownership. Placed on owned land with a permanent foundation, they hold value well and are commonly financed with chattel or land-home loans.

Modular Homes (IRC Code)

Modular homes are built in sections to the same state and local (IRC) building codes as site-built houses, then assembled on a permanent foundation. Because they meet the same codes and sit on a permanent foundation, modular homes are appraised, financed, and titled like site-built homes and appreciate similarly — with the speed, precision, and savings of factory construction.

Mobile Homes (Pre-1976)

“Mobile home” is the legal term for factory-built homes made before the HUD Code took effect on June 15, 1976. Anything built after that date is a manufactured home. People still say “mobile home” out of habit, but if you’re buying new today, you’re choosing between a manufactured or a modular home.

Common Questions

Manufactured, modular, and mobile homes

A manufactured home is built to the federal HUD Code on a permanent steel chassis and delivered ready to place. A modular home is built to the same state and local (IRC) building codes as a site-built house, delivered in sections, and set on a permanent foundation. Modular homes are financed and appraised like site-built homes; manufactured homes are often financed with chattel loans.
Legally, "mobile home" refers to factory-built homes made before June 15, 1976, when the federal HUD Code took effect. Homes built after that date are called manufactured homes. Most people still use "mobile home" casually, but if you're buying new, you're buying a manufactured or modular home.
Modular homes generally appreciate similarly to site-built homes because they use the same building codes and sit on permanent foundations. Manufactured homes hold value well too — especially on owned land with a permanent foundation — though appreciation depends on location, foundation type, and upkeep.
Usually, yes. Modular homes are built to IRC codes with heavier materials and permanent foundations, so they typically cost more than a comparable manufactured home — but still far less than site-built construction. Manufactured homes are the most affordable factory-built option.
Often you can't. Modern manufactured and modular homes offer the same finishes, layouts, and curb appeal as site-built homes. The differences are mostly in the building code, foundation, and how the home is financed and titled — not in how it looks or feels to live in.
