Hiring a General Contractor in Danville
A general contractor is the licensed party who signs the building contract and carries legal responsibility for the work. On a Danville project that means holding the permit with the Town’s Permit Center, sequencing the trades, calling inspections at the right stage, and answering for anything that fails one.
Where homeowners usually get caught out is the gap between design and construction. In the traditional setup you hire an architect, get drawings, then take those drawings to general contractors. If a structural condition turns up that the drawings did not anticipate, or the design turns out not to be buildable as drawn, you are the one standing between two companies who each point at the other.
We work as a design-build general contractor. One company and one contract cover the design, the engineering, the permit, and the build. Constructability gets checked while the design is still on paper instead of after the walls are open, and when something needs to change mid-project it changes in one place. See everything we build on our services page.
Taragano Design and Build holds California contractor license #1143420 and is bonded and insured.
Already have an architect and permitted drawings? Bring them. We are glad to work as your general contractor and build from your plans. If you want us to design it, we handle that too.
Planning a Home Renovation in Danville
Most projects that go badly went wrong on paper, months before anyone picked up a hammer. Here is the order we work in and what each stage is actually for.
Feasibility Comes Before Design
Before drawing anything we look at what the property will allow: setbacks, lot coverage, height limits, where the sewer lateral runs, whether the panel has capacity, and what the existing framing can carry. Danville sits in a narrow part of the San Ramon Valley, and hillside lots on the Las Trampas and Mount Diablo sides carry grading and drainage constraints that flat valley-floor lots do not. Finding that out first is cheaper than redesigning later.
Design and Engineering
Floor plans come first, then elevations, then structural engineering. We check constructability as the drawings develop rather than after they are stamped, which is the main practical advantage of keeping design and construction in one company.
Permits Through the Town of Danville
Danville incorporated in 1982 and runs its own planning and building review. Projects inside town limits go through the Town of Danville. Projects in Blackhawk, Diablo, Alamo, and the Camino Tassajara area sit outside town limits and are permitted by Contra Costa County instead, and gated and HOA communities usually add an architectural review step on top of that. The path is different depending on which side of the line your address falls on, and it changes the schedule.
Construction and Sequencing
Demolition, then structural, then rough mechanical, electrical, and plumbing, then inspection, then insulation and drywall, then finishes. Trades that arrive out of order create rework, so the schedule is built backward from the inspection dates rather than forward from the start date.
Home Additions in Danville
Danville’s larger lots are ideal for additions, and we match the new space to your home so it looks original. See our home additions page.
Master Suites & Primary Suites
A private retreat with a spa bath and walk-in closet. Our most requested addition, and the one that pays back most at resale.
Second-Story Additions
When the lot is full, we build up and save the yard. Going up needs structural work, and we handle it.
Kitchen & Great-Room Expansions
Push out the back wall and open the kitchen to a great room full of light.
Complete Home Renovations and Makeovers in Danville
Great bones but a dated feel? A whole-house renovation takes a Danville home down to the studs and rebuilds it modern. See our whole-house remodeling page.
Down-to-the-Studs Remodels
We rebuild the whole home: new layout, new systems, new finishes, one clear vision.
New Systems & Layout
Old wiring and plumbing out, modern and safe in. The home lives better and lasts longer.
Complete Home Makeovers
A full interior renovation without moving walls or structure. New kitchen, baths, flooring, millwork, and lighting throughout.
ADU Construction in Danville
Danville has done more than most towns to make an ADU straightforward, including a permit-ready plan program. See our ADU page, or read the Town’s own guidance on accessory dwelling units.
Detached ADU & Backyard Cottages
A self-contained backyard home with its own kitchen, bath, and entrance, sited to keep the main house’s yard usable.
Garage Conversions
Turning existing space into a real living space is often the fastest ADU path, since the shell already exists.
Garden Cottage Program
Danville’s Garden Cottage Program offers free permit-ready plans that have already been plan checked, so they qualify for expedited review and reduced permit fees. Detached units only. We build from a Garden Cottage plan or design a custom unit.

Tear-Down & Rebuild

Kitchen Remodeling in Danville
The kitchen is the room you use most, and layout decides whether it works long before any finish does. We plan around workflow, zones, lighting, storage, and ergonomics. See our kitchen remodeling page.
Layout & Workflow
Where the sink, range, and refrigerator sit relative to each other, and whether an island helps or blocks. In a Greenbrook or Sycamore ranch home this usually means removing a wall, which makes it a structural question too.
Cabinets, Counters & Light
Custom cabinets, stone counters, and a lighting plan that covers task, ambient, and accent rather than one fixture in the middle of the ceiling.
Bathroom Remodeling in Danville
A bathroom is a waterproofing problem wearing tile. We design for ventilation, drainage, and natural light first, then finishes. See our bathroom remodeling page.
Primary Suites & Spa Baths
Curbless showers, correct slope to drain, bench seating, tempered glass, and soaking tubs where the space genuinely supports one.
Hall & Guest Baths
Smaller footprints where ventilation, outlet placement, and storage matter more than square footage.

Neighborhoods We Serve In and Around Danville
Danville’s housing stock spans roughly a century, from pre-war homes near the old downtown to estates built in the last twenty years. Era and lot size decide what is worth doing, so the right move in a 1960s ranch tract is rarely the right move on a hillside acre.
Inside Danville Town Limits
Westside Danville
West of I-680, established homes on some of the larger lots in town, with mature trees and varied architecture. Room to push out or add a detached ADU without crowding the site.
Downtown Danville
The oldest housing stock in town on the tightest lots. Setbacks and neighboring structures usually rule out sprawling additions, so the work tends toward whole-house renovation or going up.
Greenbrook
Single-story ranch tract homes from the 1960s and 70s with repeating floor plans and original compartmentalized layouts. Common projects are opening the kitchen to the family room and adding a primary suite.
Sycamore and Sycamore Valley
Established family neighborhoods, largely 1970s and 80s, many already two-story. Kitchen and great-room expansions at the back of the house are the usual path here.
Crow Canyon Heights
A 94526 subdivision on the Danville side of Crow Canyon Road, close to the Iron Horse Trail. Compact lots, so interior renovation and second-story work outnumber ground-floor additions.
Magee Ranch and Diablo West
Newer custom and semi-custom homes toward the Mount Diablo foothills. Hillside parcels bring grading, drainage, and retaining questions into the design early.
Surrounding Communities
These addresses carry Danville and nearby mailing names but sit outside town limits in unincorporated Contra Costa County. Permits go through the County rather than the Town, and several add an HOA architectural review on top. We work in all of them.
Blackhawk
Gated, 94506, unincorporated county with an active architectural review committee. Visible exterior and landscape changes generally need committee approval before a permit application moves.
Diablo
94528, at the foot of Mount Diablo. Some of the oldest estate homes in the area, which means original framing and systems that need real investigation before design.
Alamo
94507, just north of Danville. Larger unincorporated parcels that suit additions and detached ADUs, permitted through Contra Costa County.
Camino Tassajara
The rural corridor east and south of town with the largest parcels in the area. Septic, well, and access questions come up here in ways they rarely do inside town limits.
Common Questions for a Danville Remodeling Contractor
How long does a Danville project take?
An addition or ADU takes three to six months for design and permits, then four to eight months to build. A full remodel can run six months to a year.
Do you handle Danville permits?
Yes. We manage the whole process with the Town of Danville Permit Center, start to finish.
Do I need an architect before hiring a general contractor in Danville?
Not with a design-build contractor. We handle design, engineering, permits, and construction under one contract, so one company is accountable from first sketch to final inspection. If you already have an architect and drawings, we are glad to build from them.
