What is a Prefab ADU

With the high cost of housing, a new model of housing has emerged – the Prefab ADU. These small, highly customized homes are taking backyards across the US by storm, enabling homeowners to build homes on their land that can be lived in by their children or parents, or rented out to tenants.

What is a prefab ADU

An Prefab ADU (Accessory Dwelling Unit) is a second dwelling unit with complete independent living facilities for one or more persons. They are also known as prefab guest houses, casitas, in-law suites, or backyard houses. As the name suggests, ADUs are smaller than existing homes, ranging in size from 500 to 1,000 square feet (approximately 46.5-93 square meters). Similar to a standard home, Prefab ADUs have all the space and amenities tenants need to live comfortably, including a kitchen, bathrooms, living/sleeping space, and a completely separate entrance from the main unit for privacy.

Advantages of Prefab ADU

Prefab ADUs have many advantages such as low cost, short build times, flexible customized designs and sustainability.

Cost-effectiveness

Prefab ADUs are much cheaper to build than traditional homes and often require less labor. They also have lower maintenance costs and can increase the value of the property. Since ADUs are purchased according to the menu of the Prefab ADU manufacturer, and the raw materials of these prefabricated components are purchased and produced collectively, the cost is much lower. According to Solidhome’s estimates, prefab ADUs can cost as low as $80,000, while stick-built ADUs can range from $150,000 to $300,000.

Streamlined construction timeline

As prefab ADUs are manufactured in mass production in component factories and assembled on-site in a model. Then the assembly time on site will be greatly reduced, so the construction time on site will be shortened. Prefab ADUs can be installed in as little as a few weeks, while stick-built ADUs can take several months to complete. They require less site preparation and disruption than building an ADU from the ground up. They also avoid weather delays and material shortages that can affect conventional construction.

Flexible and customizable design

Generally prefab ADU manufacturers will have a variety of sizes, styles and floor plans in which customers can choose their favorite type. Of course customers can make their own requests and Prefab ADU manufacturers make custom production to meet different needs and preferences. They can also be customized with features such as skylights, decks or smart home systems, solar power systems and more.

Sustainability

Prefab ADUs are environmentally friendly and sustainable by design. They use less materials and energy than traditional homes and produce less waste and emissions. They also feature energy-efficient appliances, insulation, and windows that reduce the utility bills and carbon footprint. Some prefab ADUs even have solar panels, rainwater harvesting, and composting systems that make them more self-reliant and eco-friendly.

Prefab ADU homes are a popular option for homeowners who want to maximize their living space and create a versatile and comfortable backyard home. However, before building a prefab ADU home, it is important to check the local zoning laws and regulations, as they may vary depending on the location, size, and type of ADU.
