According to the U.S. Department of Housing and Urban Development (known as HUD), the difference between manufactured, modular, and mobile homes all comes down to differences in construction and safety.
Manufactured and mobile homes must be built according to HUD’s building codes while modular homes must follow local, state, and/or regional building codes.
Mobile, manufactured, and modular homes are considered “prefabricated homes.” Also known as prefab homes, these houses are actually manufactured and built separately at a factory, delivered to your property, and then assembled.
The concept of pre-built homes is not a new one; for centuries these movable structures have been discovered in many different areas of the world. In fact, in the early 1900’s, Sears Catalog Homes actually allowed consumers to purchase prefabricated homes via mail-in order.
Homes of this nature offer potential homebuyers an alternate route to traditional homeownership. Depending on the type of prefab home, they also offer you more flexibility in terms of cost.
So, what exactly are mobile homes? They’re homes built off-site that can be relocated with more ease than a traditional home. Mobile homes in the United States were built prior to June 15, 1976, when HUD developed new Manufactured Home Construction and Safety Standards.
- Construction – Mobile homes are often built on wheels for ease of relocation. Known as “trailers” or “caravans,” they are built using a variety of materials.
- Home Design Options – Mobile homes vary in their design and can be customized to fit anyone’s lifestyle.
- Safety – One of the major drivers of the 1976 policy development was safety. Mobile homes prior to this time were not regulated and therefore could be built according to a wide variety of standards (or lack thereof). Mobile homes do not follow current HUD regulations.
- Cost – While mobile homes were once a more affordable homeownership option for many Americans, these types of homes are no longer made due to HUD policy changes in 1976. They have since been replaced by manufactured homes.
According to HUD, manufactured homes are any pre-built homes built after June 15, 1976.
Mobile home vs manufactured home
The difference between a mobile and manufactured home is the date the home was built. Prior to the date mentioned above, they were known as mobile homes.
Manufactured homes can be easily relocated, typically cost less than homes built on site, and have a variety of design options. They’re also available in several sizes: single wide, double wide, and triple wide.
Single-wide homes are generally a single section and range 18 feet or less in width and 90 feet or less in length.
Double-wide homes are slightly wider, at 20 feet or more and the same length wide. However, they are generally built in two sections as opposed to single-wide homes. Similarly, triple-wide homes are built in three or more sections with varying widths and lengths.
Both double- and triple-wides are less narrow than single-wides and are more similar in floor plan and appearances to site-built homes.
- Construction – Constructed in a climate-controlled building facility away from the property location, these homes are assembled in a single piece before being delivered to the homebuyer. Electrical, storage such as closets, plumbing, and stairs are generally built at the facility.
- Home Design Options – Manufactured homes can be easily customized. For example, you can choose finishes, flooring, and the design of your manufactured home’s kitchen, bathroom, and more. Depending on the size home you choose, you can expand your house to include more rooms.
- Safety – Manufactured homes must follow strict safety regulations set by HUD. These regulations and standards mean homes must meet certain thresholds of structural strength and element resistance against wind, storms, and even corrosion, animals, and insects. Internal and external inspections are required during and after construction to ensure the house has safe living conditions.
- Cost – According to the U.S. Census Bureau, as of August 2020, the average manufactured home sells for around $88,000 USD, while an on-site home averages around $335,000 USD. While they tend to be less expensive than on-site homes, customizations, location, and materials can drive the price up. However, they do not appreciate the same way on-site built homes do.
Modular homes, like manufactured ones, are constructed in a climate-controlled off-site facility.
So, is a modular home the same as a manufactured home?
No, the difference between modular and manufactured homes is that modular homes are assembled in modules, or large sections. Once each section is completed, it’s transported to your property location and assembled on a foundation there.
Unlike manufactured ones, they don’t need to follow federal HUD regulations. Instead, construction of modular homes must adhere to local, state, and regional code requirements.
Another major difference between modular and manufactured homes is their ability to be relocated. Once modular homes are built, they cannot be moved.
- Construction – If you’re wondering how to tell if a home is modular, look at where and how they are built. Like on-site homes, they are built on a permanent foundation compared to on a chassis like manufactured/mobile homes. However, if it’s built off-site, it’s considered modular. Also, electrical, plumbing, foundation, and sewage aren’t included; these necessities must be built on-site.
- Home Design Options – Options for customization are endless with modular homes. You can choose a variety of add-ons including finishes and flooring. Modular homes can also be built to be more energy-efficient and environmentally-friendly.
- Safety – All modular homes, like on-site homes, must be inspected during and after the construction phase prior to delivery by third party inspectors to assess if they’re up to local, state, and regional code.
- Cost – Once built, modular homes are considered real estate and appreciate like on-site built homes. They can be more affordable than on-site options since there are built in factories, making construction faster, and aren’t subject to weather delays.
