Common questions
How big is the 1 Bedroom ADU?
It has 480 sq ft of interior space — a private bedroom, an open kitchen, living and dining area, a full bathroom and a separate laundry room — plus a 96 sq ft covered deck. Outside it measures 24’ × 24’.
Who is the 1 Bedroom ADU for?
It suits long-term renters, aging parents or adult children who want their own door, and anyone who needs a separate bedroom rather than an open studio.
What's the difference from the Large Studio and the 2 Bedroom?
The Large Studio ADU is 320 sq ft with the bed in the main room. The 1 Bedroom ADU adds 160 sq ft and a private bedroom. The 2 Bedroom ADU is 640 sq ft with two bedrooms.
How much does it cost?
The 1 Bedroom ADU is $214,900 all in. That includes the foundation, permits, delivery, the crane, utility hook-ups and final inspection. Launch pricing (30% off our published home prices) runs through December 31, 2026.
How long does it take?
Four to six months from signing to keys. Your permit is under review while we're already building the home in our factory.
Can I rent it out?
Yes. Estimated rent for a unit this size is about $2,100 – $3,000 a month, based on HUD Fair Market Rents for major California metros. Actual rent depends on location and finishes.
Is it solar-ready?
Yes. It's all-electric with ENERGY STAR appliances and comes with a mounting frame designed for a solar array, so panels can be added now or later.
Is there a warranty?
Yes — a 2-year limited warranty against defects in materials and workmanship.
