What size ADU do you want to build?(Required)

The first choice to make is the size of the dwelling you want to build. Rather than think in terms of square footage, we find it more useful to think about the number of bedrooms you want to have and how many people you'd like to be able to host at the property. We've listed a base price range for each option.

Studio (Sleeps 1-2)

Base Price: $80K - $119K

1 Bedroom (Sleeps 2-4)

Base Price: $120K - $149K

2+ Bedrooms (Sleeps 5+)

Base Price: $150k +

Flooring(Required)

We offer three standard flooring options. While some options, such as hardwood flooring, are more expensive than others, each of these choices is a high-quality, long-lasting option for your ADU's floors.
