ADU designs can come in a wide range of styles often determined by several factors: primary and future uses; construction method; permitting restrictions; characteristics of the main house and neighborhood; and climate & geography.

Being strong proponents of ADUs for the many benefits that they can provide property owners, we find it encouraging to discover the range of designs being built. Here are just a few favorite examples for your viewing pleasure!
