Frequently asked questions
How much does a garage cost in Santa Rosa?
HomeGuide's national figures put a new garage at $15,000 to $80,000, and a 2-car garage at $25,000 to $60,000. Those are not our prices. Soil, fire zone rules and seismic design change Santa Rosa jobs, so we quote your lot in writing after seeing it.
Can I build an ADU in or over my garage?
In most cases, yes. California law allows garage conversions and new ADUs on lots with a home, limits setbacks to four feet for new ones, and bars cities from requiring replacement parking for a converted garage.
Do garages here need wildfire materials?
In Fire Hazard Severity Zones and Wildland Urban Interface areas, yes: a Class A roof, ignition-resistant siding, ember-resistant vents and tempered glass. We check the zone for your address.
Will my garage be built for earthquakes?
Yes. Garage walls next to the big door opening get shear bracing, and the frame is tied to the slab with anchor bolts and hold-downs as the plans require.
Can you replace my old detached garage?
Yes. We tear down the old garage, remove the slab, prepare the ground and build a new garage, often on the same footprint if zoning allows.
Do you work outside Santa Rosa?
Yes. We serve Santa Rosa, Rohnert Park, Petaluma, Windsor, Healdsburg, Sebastopol, Cotati, Sonoma, Kenwood, Glen Ellen, Novato and Napa.
How much does a new garage cost in Santa Rosa?
It depends on the size, detached or attached, the slab and site work, and the finish inside. We look at the lot and give you a written quote.
Do I need a permit to build a garage?
Almost always. New garages, additions and conversions need building permits and often zoning review. We check what your lot needs before work starts.
Detached or attached: which costs less?
It depends on the lot. Attached garages share a wall but must tie into the house; detached garages need their own four walls. We price both when the lot allows.
How long does a garage take to build?
Most garages take several weeks of work once permits are in hand, depending on size and how finished the inside is.
Can you build a room or apartment above a garage?
Often, where zoning allows. It needs a stronger frame and foundation, stairs and its own permits. We check the rules for your address.
