Barndominium Builders in Santa Rosa, California

Santa Rosa sits in Sonoma County, in the heart of wine country, and it is where many Bay Area buyers first look when they want a home with a real shop. Interest in barndominiums in Santa Rosa tends to split two ways: a house-and-workshop build on one of the larger lots inside the city, or a place on acreage in the hills and valleys just outside it. The city side is straightforward. The Planning and Economic Development Department's Building Division checks plans against state and local codes and inspects the work, the Zoning Code sets what each district allows, and Santa Rosa Water runs the sewer, so a city lot rarely needs septic. The fire history is the local fact no buyer here overlooks. The October 2017 fires destroyed more than 3,000 homes inside the city, about one in twenty of its houses. A steel frame with metal roofing and siding appeals to owners rebuilding in the hills, but it still has to meet the wildfire construction rules for its zone. Barndominium kits suit owners who will raise the shell themselves. Send us the parcel and we check its zone, fire designation and utilities first.

Barndominium Kits and Plans for Santa Rosa

A kit is the steel or pole barn package for an owner or a hired crew to put up; a custom plan fits the shop bay and the living space to the parcel. Either way the land sets the budget more than the floor area does, so each option is priced against your site rather than a rate card.

Barndominium Builders and Pole Barn Homes near Santa Rosa

A pole barn home sets its frame on posts and trusses (the engineering term is post-frame), which often suits a simple, wide layout with a shop bay under the same roof. A turnkey build takes the project from the pad to the finished house. Whether either fits your parcel comes down to the zoning, the septic and the water, set out below.

Permits, Zoning, Septic and Wells in Santa Rosa

Four questions decide whether a barndominium works on a parcel before any steel is ordered. Here is who answers each of them in Santa Rosa, taken from the office or document that publishes it. Rules change, so check them again against your parcel before anything is drawn.

Who issues the building permit City building department

City of Santa Rosa Planning and Economic Development Department, Building Division

The Building Division reviews building permit applications for compliance with state and local codes, covering structural, electrical, mechanical, plumbing, green building and energy work, and inspects all building construction. It also runs code compliance. Meetings are by appointment. Land outside the city limits is permitted by Permit Sonoma, the County's agency.

Who decides the land use City zoning

City of Santa Rosa Planning Division

The Zoning Code's tables list the land uses and permit requirements for each zoning district: a use marked P is permitted after a Zoning Clearance, while others need a Minor Use Permit or more. The Planning Division gives final determinations on zoning by email, and new ordinances not yet folded into the code are listed as New Laws.

Sewer or septic Public sewer

Santa Rosa Water; Laguna Treatment Plant

Santa Rosa Water handles wastewater collection, treatment and reuse for the city, and its operators look after nearly 1,200 miles of water and sewer pipe and 17 wastewater pump stations. A home inside the city normally connects to that sewer.

Private water wells Wells: county permit

Permit Sonoma, Well and Septic Division

Permit Sonoma's Well and Septic Division issues water well permits for Sonoma County land. Drilling, deepening or abandoning a well needs a permit first, and the permit is issued only to a C-57 licensed well contractor.

The October 2017 fires
The City of Santa Rosa reports that the Sonoma Complex Fires of October 2017 destroyed more than 5,300 homes, including 3,043 within the City of Santa Rosa, about 5 percent of its housing stock, and caused an estimated 100,000 people to evacuate countywide.

Metal Building Homes near Santa Rosa

A metal building home uses a steel frame and steel skin, with the clear span to open up a shop, a garage bay or a great room without interior posts. The structural design is set for your site by the engineer and the building official.

Where the Land Is near Santa Rosa

Santa Rosa proper is neighbourhoods, shopping streets and business parks on the city sewer, and a lot big enough for a large shop plus animals is hard to find inside it. The acreage starts where the city stops. Vineyards and pasture across the Santa Rosa Plain, and oak hills to the east and north, are unincorporated Sonoma County, where one agency, Permit Sonoma, decides zoning, building, septic and wells.

Building on Land near Santa Rosa

Look up the parcel's zoning district and check the use table before you buy, because some uses need a Minor Use Permit rather than a simple Zoning Clearance. Then check the fire hazard designation on the State Fire Marshal's viewer; in a designated zone, the house is built to the California Wildland-Urban Interface Code, which covers the roof, vents, siding, windows and decks. On a lot that burned in 2017, confirm what the current zoning allows rather than relying on what stood there before. Confirm the sewer connection, and allow for the drive and turning space a wide shop door needs.

Building in Santa Rosa: questions

Start the survey
How much does it cost to build a barndominium in Santa Rosa?
A Santa Rosa price depends on the parcel as much as the plan: fire-zone construction on hillside lots, the sewer connection, grading and the foundation for a shop slab. We quote from the actual lot. Per-square-foot ranges, with sources, are in our barndominium cost guide.
Do I need a building permit for a barndominium in Santa Rosa?
Yes. Inside the city limits the Building Division reviews the plans for code compliance and inspects the construction. If your land is outside the city, Permit Sonoma issues the permit instead; see our Sonoma County page.
What zoning does a barndominium need in Santa Rosa?
Usually, where a single-family home is a permitted use in the district and the building fits its height, setback and coverage standards. The Zoning Code's use tables show whether a Zoning Clearance or a use permit is needed. Send the address through the survey and we will check it.
Does wildfire risk change how a barndominium is built in Santa Rosa?
It can. Where a parcel is in a Fire Hazard Severity Zone, the home is built to the state's wildland-urban interface rules for roofs, vents, walls and windows. Metal roofing and noncombustible siding are among the listed options, and the building department confirms the specific assembly.
