Decks & Patios in Sonoma, CA
Custom decks and patios built for California living.
Decks & Patios in Sonoma starts with understanding the local housing. Sonoma is one of the Sacramento-area, foothill, and Tahoe communities in Sonoma County that we serve across Northern California.
Around Sonoma, seismic design and hillside wildfire exposure are part of planning decks & patios, alongside a mix of historic downtown homes and newer hillside construction.
This page covers decks & patios specifically for Sonoma. For the full service details, see our Decks & Patios page, or explore all the remodeling work we do in Sonoma.
Sonoma is a small, upscale Wine Country town with an unusually rich and historic housing stock. The area around the Sonoma Plaza — a National Historic Landmark and the largest town square in California — holds early adobes, Victorians, and period homes governed by historic-preservation expectations for exterior changes. Radiating out, the East Side and West Side neighborhoods mix bungalows, mid-century ranches, and custom homes, while Diamond A Ranch, Temelec, and Chase Ranch add later subdivision and active-adult housing. Beyond the flats, wine-country estates and hillside homes climb into the surrounding hills, where wildland-urban-interface fire exposure makes ignition-resistant materials and defensible space real considerations, and Sonoma County's seismic risk makes retrofit relevant for older homes. This is a market where homeowners invest in meticulous kitchen, bath, and whole-home renovations, additions, and outdoor-living spaces that respect the town's character, with hot, dry summers keeping Title 24 energy efficiency in the plan.
From Sonoma Plaza / historic downtown, East Side, and West Side to the rest of Sonoma, we match every decks & patios project to the age, construction, and condition of your specific home rather than a one-size-fits-all spec.

Site Assessment & Design
We evaluate your yard's grade, drainage, soil, and sun exposure — all of which matter on hillside and expansive-soil lots — and design a deck or patio with material options and a fixed-scope estimate.
- 02
Permit & Layout
We prepare drawings and pull permits where required. Elevated and attached decks generally need a permit, engineered connections, and inspections; we handle that for your jurisdiction.
- 03
Foundation & Structure
Deck footings and piers are engineered and set for your soil and slope, with seismic connections tying the structure to the home. Patio bases are excavated, graded, and compacted before the surface goes down.
- 04
Surface & Finishing
Decking, pavers, or concrete are installed, followed by railings, stairs, and lighting. We complete a final inspection and share care guidance.
Typical timeline: Typically 1 – 4 weeks. We provide a written schedule after assessing your Sonoma home.
Permit requirements for decks & patios in Sonoma are handled through City of Sonoma. Because California building rules — including the Title 24 energy code and local amendments — vary from one jurisdiction to the next, we confirm what your specific address requires and pull the permits and schedule the inspections the scope calls for.
- Permits are required for structural, electrical, plumbing, and mechanical work
- Exterior changes near the historic Plaza and in designated historic areas may require design review
- Hillside homes in wildland-urban-interface fire zones must use ignition-resistant materials under California Building Code Chapter 7A
- Envelope, HVAC, and window replacements must meet California's Title 24 energy code, and ADUs receive ministerial approval under state law — we prepare and submit all applications

How are deck footings handled on a hillside lot?
Hillside and expansive-soil lots — common across the foothills and much of the region — call for engineered footings or piers sized to the soil and slope, with the deck tied back to the home using seismic-rated connections. We build to your jurisdiction's engineered design and have it inspected before framing so the structure stays put.
Composite or wood for a Northern California deck?
Composite handles our strong sun and dry heat with less upkeep — it won't rot, splinter, or need annual staining, though it costs more up front. Redwood and cedar are beautiful and regionally traditional but need regular sealing. In fire-hazard areas we'll also discuss non-combustible or ignition-resistant decking. We help you weigh cost, look, and maintenance.
Do I need a special deck for a fire-hazard area?
Often, yes. In Wildland-Urban Interface and fire-hazard severity zones, California's Chapter 7A addresses decks and calls for ignition-resistant or non-combustible materials, since a combustible deck can be an ember-catcher against the home. We'll confirm your zone and specify compliant materials where they apply.
Do I need a permit for a deck?
Most attached or elevated decks require a permit, engineering, and inspections, and requirements vary by city and county. Ground-level patios often don't, unless they affect drainage or setbacks. We confirm and handle permitting for your address.
Do I need a permit for decks & patios in Sonoma?
It depends on the scope. City of Sonoma sets the requirements for Sonoma, and they can differ from neighboring California jurisdictions. We confirm what your project needs before we start and handle the permit and inspection process as part of the job.
Do you handle decks & patios on both older and newer Sonoma homes?
Yes. From Sonoma Plaza / historic downtown, East Side, and West Side to the rest of Sonoma, Sonoma in Sonoma County spans a range of housing eras and construction types, and we tailor the decks & patios plan to the age and condition of your specific home rather than a one-size-fits-all template.
