Our in-house design team is adept at tailoring plans to align seamlessly with your main residence, ensuring the exterior of the ADU blends with the property. From minor adjustments to bespoke guest house plans to stacked ADUs, we provide a spectrum of options to meet your unique needs for your ADU house plan.

For ADU construction, stick-built shines for those wanting customization, dealing with tricky lots or HOAs, or building multiple larger units. SnapADU specializes in design build with on-site traditional wood framed construction. We offer unmatched value for larger ADUs or multi-unit projects. Meanwhile, a prefab ADU could be a better option for a smaller build or on a spacious, flat lot. Choosing between prefab and a stick-built ADU contractor hinges on your site’s specifics, investment goals, and whether your project calls for a bespoke design. Read more in our guide to prefab ADUs.
