Build an ADU that earns its keep
Add living space, rental income, and property value with a smart, code-compliant accessory dwelling unit. Cobi Construction handles end-to-end delivery—feasibility, design, engineering, permits, utility coordination, inspections, and finishes—so you get a turnkey backyard home, guest suite, office, or multigenerational unit without the headaches. We optimize layouts for comfort and privacy, plan efficient MEP runs to reduce cost, and manage city communication to keep your submittal moving. Expect durable materials, clean details, and energy-efficient systems that lower monthly bills and boost long-term ROI. Need accessibility, sound control, or home-office wiring? We spec it in from day one. You focus on how you'll use the new square footage; we handle everything else through final occupancy.
ADU types we deliver
Detached backyard cottages (studio–2BR, often up to 1,200 sq ft depending on local code). Attached additions that blend seamlessly with your main house. Garage conversions and JADUs (typically up to 500 sq ft) that reuse the footprint for speed and savings. Above-garage suites and basement conversions where structure allows. Options include full kitchens and baths, laundry, built-ins, skylights, and private patios. We design for solar readiness and Title-24 energy compliance, specify quiet heat-pump HVAC and water heating, upgrade panels/subpanels, and address fire separation and egress requirements. Universal-design features, acoustic insulation, EV-ready circuits, and smart-home wiring are available in every package.
From permit to keys: our process
Feasibility & budgeting → site walk, setbacks, height/lot coverage check, utility mapping, preliminary schedule, and an itemized estimate with allowances. Design & engineering → as-builts, architectural plans, structural calcs, Title-24, finish schedules, and value-engineering to keep scope aligned to budget. Permitting → submissions, plan-check responses, corrections, and coordination on parking (often exempt near transit; local rules vary). Build → site prep, foundations, framing, MEP rough-ins, insulation, windows/doors, drywall, tile/millwork, fixtures, HERS testing, and final inspections. You get clear milestones, weekly progress updates, and one point of contact—from demo to punch list to close-out manuals and warranty.
Costs, timeline, next steps
We price transparently with detailed scopes and finish allowances, then lock schedule and cost before we mobilize. After a quick feasibility review, we share typical ranges for your lot and preferred spec, plus options for phased upgrades. Common financing paths include HELOC, construction loan, and cash-out refi; we can coordinate lender docs and draws. Timelines run in two stages: design/permitting (jurisdiction-dependent) and a focused build window measured in weeks with predictable inspections. To get started, request a free feasibility consult—send your address/APN, a couple of site photos, any survey or lot map, preferred size/bed count, and your goal (rental, family, office). We'll confirm what fits by-right, flag constraints early, and map the fastest path from permit to keys.
