Frequently Asked
How long does it take to build an ADU in California?+
From design to completion, most Betters ADU projects take 4-6 months. Our factory-built modules significantly reduce on-site construction time compared to traditional builds.
Do I need to live on the property to build an ADU?+
No. Recent California legislation (SB 9 and AB 68) removed owner-occupancy requirements for ADUs in most jurisdictions, making it easier than ever to build for rental income.
What is the maximum size ADU I can build?+
In California, attached ADUs can be up to 50% of the primary dwelling's floor area (up to 1,200 SF), and detached ADUs can be up to 1,200 SF. Local regulations may vary.
Can I rent out my ADU for short-term stays (Airbnb)?+
Short-term rental rules vary by city. Many California cities restrict short-term rentals of ADUs, but long-term rentals (30+ days) are generally allowed statewide.
