Why homeowners choose this

Attached ADUs done right.

Keep your yard

Attached ADUs add square footage without eating into outdoor space, so kids, pets, and gardens stay intact.

Lower cost than detached

Sharing a wall and utilities with the main house often makes attached ADUs more affordable per square foot.

Seamless connection

Perfect for aging parents or adult children who want proximity with the option for privacy.

Easier utilities

Power, water, and sewer ties are usually simpler because the unit connects to your existing home systems.
