McCain Homes: Prefab Accessory Dwelling Units
McCain Homes is a line of prefabricated accessory dwelling units (ADUs) designed to address a growing need for affordable and environmentally conscious housing options. As an ADU builder, McCain Homes offers an alternative to traditional construction methods, with units that cost approximately 20 percent less than a conventional build and can be completed in roughly one-third of the time.
The homes are constructed using sustainable, modular wall systems made from over 90 percent recyclable metals. This approach replaces the standard drywall and framing method with prefinished components that can be assembled in hours rather than weeks, making McCain Homes a notable option in the accessory dwelling unit builder space.
ADU Models and Floor Plans
McCain Homes offers a range of models to suit different needs and lot configurations. Their available series includes:
- Studio Unit – A customizable 400-square-foot unit that homeowners can expand over time based on their requirements.
- 500 Series – A 490-square-foot model featuring a combined living and kitchen area, a bathroom with shower and washer/dryer space, and a bedroom sized for a queen bed.
- 700L Series
- 700L2 Series
- 700 Series
- 1K Series
These units are suited for a variety of uses, including primary residences, rental properties, in-law suites, granny flats, home offices, or personal hobby spaces. The modular nature of the construction allows for flexibility in both design and application.
