This Huntington Beach project on Quill Cir is a ground-up 320 sq ft new construction ADU — proof that a compact footprint can still deliver a complete, comfortable living space.
Every inch works: a full kitchen, bathroom, and living/sleeping space in a unit that's efficient to build and to maintain.
Compact ADUs like this are ideal where lot coverage or setbacks limit what can be built, and they still generate meaningful rental income in a coastal market like Huntington Beach.
Watch the video walkthrough to see the finished unit. Vision ADU handled the build from foundation through final inspection.
