Licensed California general contractor
Calyx Builder is a licensed California general contractor. We plan, price and build new homes, renovations and commercial spaces — and the person leading your project is on this page.

Services
Houses, commercial space and the work that changes what is already standing.
New houses built to your drawings on your lot, from foundation to final inspection.
Ground-up commercial buildings and tenant improvements for offices, retail and light industrial space.
Kitchens, bathrooms and whole-house remodels, including the structural, electrical and plumbing work behind the finishes.
One person owns the schedule, the subcontractors, the inspections and the budget, and reports to you on all four.
Energy-efficient envelopes, all-electric systems and solar-ready roofs, specified at the drawing stage rather than added later.
Room additions and accessory dwelling units, permitted and built to tie into the existing house.

How we work

We walk the site with you, see what is there and hear what you want built. You find out early whether the project is practical and what it will involve.
We work from your architect’s drawings, or help you get them, and write down exactly what is in scope. Decisions get made on paper, where changing them is cheap.
An itemized estimate based on the site and the drawings, so you can see what each part of the work costs and what is not included.
One project lead runs the job, checks each phase before the next one starts, and is the person you call. The people who priced the work stay answerable for it.
Questions
Call (209) 597-4383 or send the form below. We arrange a site visit, look at what is there and what you want, and tell you what happens next.
Custom homes, commercial construction, renovations & remodels, sustainable building and additions & adus. We also manage projects from drawings to final inspection.
Calyx Builder holds California contractor license #1122449, Class B — General Building Contractor, issued by the Contractors State License Board. You can check its status yourself on the CSLB website.
Check the license on cslb.ca.govWe price after we have seen the site and the drawings — a number before that is a guess. The estimate is itemized, so you can see what each part of the work costs and what is not included.
Every change is written up as a change order with its cost and its effect on the schedule, and you sign it before the work changes. Nothing is added to the bill that you have not agreed to in writing.
We are based in Livermore and work across the Bay Area. If your project is outside that, ask — it depends on the size of the job.
