What is the difference between Custom and Prefab ADUs?

Custom:
A Custom ADU is site-built on your property to meet your exact specifications. This option offers complete flexibility in design, materials, and layout to perfectly match your vision and the existing aesthetics of your property. Ideal for unique requirements and personalized finishes.

Prefab:
A Prefab ADU is a pre-designed, factory-built unit that is delivered fully assembled to your property. This option is typically faster and more cost-effective than custom builds, with a variety of design options to choose from. Perfect for those seeking a streamlined and efficient solution.
