Why Choose A Modular ADU?
Choosing a modular ADU (Accessory Dwelling Unit) offers several advantages that make it an attractive option for homeowners in the Bay Area. Here are some key reasons to consider a modular ADU.
Quality Control
Modular ADUs undergo rigorous quality control measures during the manufacturing process. The controlled environment of the modular ADU Bay Area factory allows for precise construction techniques, adherence to building codes, and consistent craftsmanship.
Minimal Site Disruption
This type of ADU requires less on-site construction time and labor than traditional ADUs. The result? Less disruption to your main property during the installation process. The off-site construction also minimizes noise, dust, and inconveniences from construction.
Customization
Despite being factory-built, prefab ADUs offer a range of options to fit your needs and preferences. From layout configurations and interior finishes to exterior design elements, you can work with the modular ADU experts to personalize your unit.
