Frequently Asked Questions
Have a question we didn't answer? Text us and we'll get right back to you.
Why does your permitting process go faster than other Palo Alto builders?
We draft plans against the City of Palo Alto's own plan-check checklist before submittal, so most of our packages clear in the first review cycle instead of bouncing back for corrections. That single change is usually what separates a 2-month approval from a 6-month one.
What does a detached or garage-conversion ADU cost in Palo Alto?
Detached backyard builds typically land between $180,000 and $400,000+ depending on size and finish level; garage conversions and JADUs start lower, around $65,000 to $95,000. Text us for a site visit and we'll return a firm, itemized number fast.
How fast can construction actually start once my permit is approved?
Because we schedule crews and materials ahead of approval, most of our Palo Alto clients see groundbreaking within days of getting their stamped permit back — there's no separate wait to line up a construction slot.
Which ADU types can you build?
Detached backyard homes, garage conversion ADUs, Junior ADUs (JADUs), attached additions, and prefab/modular installs — plus standalone design and permitting if you just need the paperwork moved quickly.
Can a finished ADU be rented out?
Yes — a completed, permitted ADU can generally be rented long-term under California and Palo Alto rules. Short-term rental restrictions vary by city, and we'll walk you through the current ones for your address.
Is design, permitting, and construction handled under one contract?
Yes. One team runs plans, structural engineering, City of Palo Alto permit tracking, and the build through final inspection — a single point of contact keeps every phase moving without hand-off delays.
