Is a Double Wide Home Identical to a Modular? Decoding the Differences

Yes, double-wide and modular homes are both forms of prefabricated housing. However, there are several key differences that distinguish the two. The most notable difference between the two is the foundation upon which they are built. Here are some additional differences:
  • Construction: Double-wide homes are manufactured on a movable steel frame or chassis and are designed to be transported to the intended location. On the other hand, modular homes are made in sections, referred to as modules, in a factory, and are assembled at the home site.
  • Design: Double-wide homes generally come in box shapes due to building standards set by the Department of Housing and Urban Development (HUD). Modular houses, on the other hand, have a greater range of design options because they are built in distinct modules that can be arranged and combined in a variety of configurations to create a unique design.
  • Cost: Modular homes are typically more expensive than double-wide homes due to their higher-quality construction materials and design flexibility.
  • Resale Value: Modular homes have been shown to have a higher resale value than double-wide homes due to their consistent quality and lack of depreciation.
  • Customization: Since modular homes are built in sections and assembled on-site, they offer more customization options than double-wide homes. In conclusion, while both double-wide and modular homes fall under the category of prefabricated housing, there are several significant differences between the two that affect their design, construction, cost, resale value, and customization options. Ultimately, choosing the right type of prefabricated housing will depend on your individual needs and preferences.

    Is a Double Wide the Same as a Modular?


    The foundation is the primary difference between a double-wide and a modular home. Double-wide homes are traditionally constructed on steel frames or trailers while modular homes are constructed on a foundation built on-site. The key advantage to a foundation for a modular home is that it offers greater stability, durability and provides a better base for the home to be built on compared to a trailer frame. A foundation allows for a modular home to be treated like a traditional site-built home and provides greater resale value.


    The construction of double-wide and modular homes differs greatly. Double-wide homes are built in a factory in two separate halves, transported to the site, and then connected together. Modullar homes, on the other hand, are built in separate sections, known as modules, inside a factory and then transported to the site to be assembled. Modular homes are built to be more energy-efficient and have a more durable structure compared to double-wide homes. The construction of modular homes is precise, which can result in less waste and damage to the surrounding environment.


    Transportation is a significant difference between the two types of homes. Double-wide homes are typically transported as a single unit on a trailer with the two halves joined together at the delivery site. In contrast, modular homes are transported in multiple pieces or modules that can be assembled on-site, much like a large Lego set. Modular homes require specialized transportation and equipment to move them to the designated site, which can add to the overall cost of the home.

    Building Codes

    Both modular and double-wide homes must meet the strict building codes that are in place in the region where they are planned to be placed. Most of the time, the codes that apply to modular homes are more stringent due to their adherence to stricter building standards. Modular homes are also often built in compliance with additional codes that are in place to ensure greater energy efficiency. Double-wide homes, on the other hand, are less regulated in terms of their building standards and may not have the same energy-saving features as modular homes.


    Modular homes offer more customization options than double-wide homes. Modular homes can be designed to be extremely customizable, as they are built to fit the specific needs and preferences of each homeowner. Additionally, modular homes can have a range of unique features added on, such as fireplaces, balconies and other custom amenities. Double-wide homes are built in a far more strict and limited design capacity, which gives homeowners fewer options for customization.


    The overall cost of a modular home is usually higher than the cost of a double-wide home. Modular homes are more energy-efficient and constructed to higher standards, which means they cost more to build. On the other hand, double-wide homes have lower upfront costs because they are less expensive to build, but they are often less sturdy, durable and potentially less energy-efficient than modular homes. The costs of foundation, transportation, and site preparation must also be considered in the overall cost of both types of homes.

    In conclusion, although double-wide and modular homes are both prefabricated houses, they differ in their foundation, construction, transportation, building codes, customization options, and overall cost. Modular homes provide a better-quality foundation – a traditional site-built foundation – and a more precise method of construction that delivers higher building standards. Additionally, you have more options to customize modular homes. Meanwhile, double-wide homes may have a lower upfront cost, but they potentially offer less sturdiness and energy efficiency, which results in fewer options for customization.
