Bay Area ADUs,
design to keys.
We've built detached ADUs, attached units, and garage conversions across San Francisco, Contra Costa, Alameda, and the Peninsula. Local permitting, in-house design, and a single project manager from initial sketch through final inspection.
We know the permits.
We've built the units.
ADUs in California are a tangle of state laws (SB 9, AB 68, AB 881), local zoning, setback rules, and utility hookup requirements that change city by city. Walnut Creek isn't the same as Concord. Concord isn't the same as Lafayette. Going it alone usually means expensive redesigns and major hold-ups.
Our team has handled ADU and JADU work across the Bay Area for over a decade. We know which setbacks the planning department actually enforces, which utility coordination conversations need to happen first, and what plans the city expects to see. You get a unit that's code-compliant, well-built, and ready to rent or move family into.
Six steps from idea to occupancy.
Initial Consultation
We sit down at your property, talk through your goals, timeline, and budget bands. We walk the site, look at setbacks and utility runs, and give you an honest read on what's feasible.
Design & Site Evaluation
Our in-house architects measure the lot, evaluate access, and produce design options. Detached, attached, or garage conversion — we lay out the trade-offs in plain English.
Permits & Approvals
We pull permits, handle plan-check revisions, and coordinate with the city or county directly. California, Contra Costa, Alameda, and San Francisco are all part of our regular workflow.
Foundation & Framing
Site prep, foundation pour, framing, roofing — your project manager runs a weekly walkthrough so you know exactly where we are.
Mechanical & Finishes
Plumbing, electrical, HVAC, insulation, drywall, paint, flooring, fixtures. We sequence subs tightly so the site keeps moving.
Final Inspection & Handoff
Final inspection passed, certificate of occupancy in hand, punch list cleared. We hand you the keys with warranty paperwork and a follow-up call scheduled.
From the foundation up.
