Manufactured Homes vs. Modular Homes

What Is a Manufactured Home and How Does It Differ From a Modular Home?

Manufactured and modular homes are both constructed in a controlled factory environment, but they are not the same type of housing. The primary differences involve how the home is constructed, the building standards that apply, and how the completed home is transported and installed.

Understanding the distinction can be important when buying, selling, refinancing, or obtaining an appraisal of a manufactured or modular property.

What Is a Manufactured Home?

A manufactured home is a factory-built dwelling constructed in accordance with the Federal Manufactured Home Construction and Safety Standards, commonly known as the HUD Code.

The HUD Code became effective on June 15, 1976, and established federal construction and safety standards specifically for manufactured housing.

Manufactured homes are typically constructed on a permanent chassis and transported to the property site. Depending on the design, they may consist of one or more sections that are assembled and installed on the site.

Once installed, a manufactured home may be placed on a permanent foundation and can have features such as additions, garages, porches, decks, and other site improvements.

For appraisal purposes, the characteristics of the home, its foundation, installation, site, condition, quality, ownership, and comparable sales can all be relevant to the valuation.

What Is a Modular Home?

A modular home is also constructed in a factory, but it is generally built to comply with the state and local building codes applicable to the property's location, rather than the federal HUD Code for manufactured housing.

Modular homes are constructed in sections or modules and transported to the building site, where they are assembled and permanently installed on a foundation.

Depending on the design, a modular home may have one or more stories and can be constructed in a wide variety of architectural styles and configurations.

Once completed and installed, a modular home can be very similar in appearance and functionality to a site-built home.

Why the Difference Matters in Real Estate Appraisal

The distinction between manufactured and modular construction can be important when determining the appropriate comparable properties and analyzing market value.

An appraiser considers the property's actual characteristics and how the local market recognizes those characteristics. The analysis may include the home's age, quality, condition, size, design, foundation, site, location, amenities, and other factors that influence marketability and value.

It is also important to identify the property correctly in public records, MLS data, and other sources. Misidentification of a manufactured home as a modular or site-built property—or vice versa—can affect the selection and analysis of comparable sales.
