VI.FAQ

ADU Construction — Frequently Asked Questions

Can I build an ADU on my lot?: Almost certainly, yes — California state law requires nearly all single-family lots to allow at least one ADU. The question is what size and configuration. We do a free feasibility walk and tell you exactly what's possible on your specific parcel.
How long does an ADU project take?: From design start to certificate of occupancy, a typical detached ADU runs 9–14 months: 2–3 months design and engineering, 2–4 months permitting, and 5–7 months construction. Conversions and JADUs are faster. We give you a documented timeline at proposal.
Do I have to live on the property to rent the ADU?: No. Owner-occupancy requirements were largely removed by AB 671 and follow-on legislation. You can build an ADU and rent both the primary house and the ADU separately, subject to local rent control rules where applicable.
What does an ADU typically cost in the South Bay?: South Bay ADU pricing has settled into roughly $400–$650 per square foot turnkey for detached new construction, depending on finishes and site conditions. Conversions of existing garages run lower per-square-foot but vary widely based on existing structure quality. We quote fixed-price after a complete design.
