On the western edge of our Napa service circle — and in our home county — Sonoma Valley has been Howard Construction territory since day one. Adobe-era charm around the Plaza, oak-woodland estates up the valley, and everything between.
Howard Construction is headquartered in Santa Rosa, which makes Sonoma Valley our backyard. From the historic blocks around Sonoma Plaza — some of the oldest built fabric in California — to Glen Ellen's creekside cottages and Kenwood's vineyard estates, we've been driving these roads to jobsites since 2000. That proximity matters practically: faster response when something needs attention, tighter supervision, and subcontractor relationships built over hundreds of local projects.
Sonoma Valley shares Napa Valley's central construction reality: fire. The 2017 Nuns Fire burned through the hills above Glen Ellen and Kenwood, and rebuilding and hardening homes here follows the same discipline we apply across the ridge — Class A roofs, ember-resistant assemblies, ignition-resistant decks, and defensible-space site planning under Sonoma County's Permit Sonoma requirements.
Whether it's a careful remodel near the Plaza's historic district, a modern farmhouse addition in Glen Ellen, or an ADU that lets the next generation stay in the valley, we bring the same promise: licensed Class B work, transparent numbers, and Phil personally on your site.
Two counties, one standard. Here's what building on the Sonoma side of our service area looks like.
City of Sonoma projects run through its Planning & Building departments, with historic-area sensitivity near the Plaza; Glen Ellen, Kenwood, and rural parcels go through Permit Sonoma, the county's consolidated permitting agency. We work both counters constantly.
The 2017 fires reshaped the valley's hillsides. For WUI parcels we build and retrofit to ignition-resistance standards as baseline scope — the same fire-hardening discipline we apply on the Napa side of the Mayacamas.
Being based in Santa Rosa means our crews, suppliers, and subs are minutes away, not hours. That shows up as tighter schedules, faster punch-list turnaround, and a contractor who can actually swing by when you call.
Kitchen, bathroom, and whole-home renovations built around your daily life — including phased work while you live in the home.
Primary suites, second stories, great rooms, and in-law wings engineered to match the existing structure seamlessly.
Detached ADUs, garage conversions, and junior ADUs handled end-to-end: feasibility, plans, permits, and build.
Outdoor kitchens, covered rooms, pool decks, and entertaining spaces built for wine-country indoor-outdoor living.
Engineered decks, pergolas, and shade structures — including ignition-resistant assemblies for WUI parcels.
Detached garages, shops, barns, and carriage houses with finished living space above.
A sample from our project gallery — real jobs, from framing to finish.



Yes — Howard Construction has held both counties as core territory since 2000. Same license, same crews, same standard; only the permit counter changes.
Yes. Work near the Plaza calls for design sensitivity to some of California's oldest streetscapes, and approvals go smoother when the submittal demonstrates that sensitivity clearly. We build to preserve character outside while modernizing everything inside.
Regularly. Rural Sonoma Valley parcels often have generous space for detached ADUs, and Permit Sonoma processes ADU applications ministerially under state law. Wells, septic capacity, and fire access are the variables we verify first — free, at a feasibility visit.
Faster than anyone trucking crews in from far away — our Santa Rosa headquarters is minutes from the valley. For active projects that means daily supervision; for warranty or punch-list items it means same-week, often same-day response.
Philip Howard personally reviews every inquiry and walks every site. One call gets you a straight answer on feasibility, timeline, and budget — no pressure, no runaround.
