Understanding Mobile, Manufactured, and Modular Housing


The terms mobile home, manufactured home, and modular home are often used interchangeably, but they actually refer to three distinct housing types. Each has unique characteristics and construction standards, and understanding their differences can be important for homeowners, buyers, and real estate professionals alike.

Mobile Homes

Mobile homes, also known as trailers or manufactured homes, are prefabricated housing first introduced in the 1920s. They were designed to be affordable, easily transportable, and often used as temporary housing for workers on construction sites or in rural areas.

Mobile homes are built on a steel chassis with wheels, which allows them to be transported to different locations. They range in size from single-wide units, less than 16 feet wide and 90 feet long, to double-wide or triple-wide units, which can be up to 32 feet wide and 90 feet long. Mobile homes are also typically less expensive than other housing types, with prices ranging from $50,000 to over $100,000 for newly built. Used mobile homes are sold for less.

However, mobile homes are less sturdy and durable than other housing types and are not built to the same construction standards. They are also subject to federal regulations requiring them to meet certain safety and energy efficiency standards. This means that mobile homes must be built with specific materials and construction techniques and must meet certain insulation, ventilation, and other requirements.

Manufactured Homes

Manufactured homes are similar to mobile homes in prefabricated housing units transported to a site and assembled on a permanent foundation. However, manufactured homes are built to stricter construction standards than mobile homes and are subject to more stringent federal regulations.

Manufactured homes are built in a factory and transported to the site in one or more sections. They are then assembled on a permanent foundation and may be connected to water, electricity, and sewage. Manufactured homes can be single-wide, double-wide, or triple-wide and range in size from 500 square feet to over 2,000 square feet.

One of the main advantages of manufactured homes is that they are built to the same construction standards as site-built homes and are subject to the same safety and energy efficiency regulations. This means that manufactured homes are typically more durable and energy efficient than mobile homes and may have higher resale values. However, manufactured homes are also more expensive than mobile homes, with prices ranging from $70,000 to $150,000.

Modular Homes

Modular homes are prefabricated housing built in sections, or modules, in a factory and transported to a site for assembly. Unlike mobile homes and manufactured homes, modular homes are built to the same construction standards as site-built homes and are subject to the same building codes and regulations.

Modular homes are typically built in sections up to 14 feet wide and 60 feet long and can be combined to create homes of various sizes and configurations. They are built with the same materials and construction techniques as site-built homes and are designed to be energy efficient and durable.

One of the main advantages of modular homes is that they can be customized to meet a wide range of design and style preferences. They can also be built quicker than site-built homes since the modules are constructed in a factory and transported to the site for assembly. However, modular homes are typically more expensive than mobile homes and manufactured homes, with prices ranging from $80,000 to $300,000 or more.


Choosing the right type of housing is a crucial decision, and understanding the differences between mobile, manufactured, and modular homes can help make that decision easier. Each type of housing offers its own unique advantages and disadvantages, and it is important to consider factors such as cost, durability, energy efficiency, and design flexibility when making a decision. By weighing these factors and considering your individual needs and preferences, you can find the perfect home that meets your requirements.
