Introduction to ADU Modular Homes

Accessory Dwelling Units (ADUs), often referred to as granny flats, in - law suites, or backyard cottages, are self - contained living units located on the same lot as a primary single - family home. Modular homes are constructed in sections (modules) in a factory and then transported to the building site for assembly. ADU modular homes combine these two concepts, offering a cost - effective, efficient, and sustainable way to add living space. They are pre - fabricated in a controlled factory environment, which allows for better quality control, faster construction times, and reduced waste compared to traditional on - site construction.
