Northern California
Commercial General Contractor

We handle new ground-up construction, tenant improvements, building remodels, retail and restaurant buildouts, medical office construction, design-build projects, and government and institutional work. We serve business owners, franchisees, investors, and commercial real estate brokers on projects of varying scale and complexity across Northern California.

Both. We most commonly serve as prime contractor and general contractor, taking full responsibility for every subcontractor, permit, and phase of the build from site prep through certificate of occupancy. We also offer standalone construction management services for owners and developers who need expert oversight without a prime contractor relationship.

We are headquartered in Redding, California and serve all of Northern California including Shasta County, Tehama County, Trinity County, Siskiyou County, Butte County, Glenn County, Humboldt County, and the greater Sacramento Valley region, north to the Oregon border. Primary service areas include Redding, Chico, Red Bluff, Yreka, Weaverville, Susanville, and surrounding communities.

We come in after architectural and engineering plans are approved and manage everything from that point through certificate of occupancy. We do not create plans ourselves but we work closely with your architect, engineer, or designer throughout every phase of the build and can recommend qualified design professionals if needed.

We coordinate directly with local building and planning departments on your behalf. Our team has extensive experience navigating the permitting process across Northern California jurisdictions, including plan check submissions, permit expediting, inspection scheduling, and certificate of occupancy sign-off.

As prime contractor we take full responsibility for selecting, vetting, scheduling, and managing every subcontractor on the project. We maintain established relationships with qualified trade partners across Northern California including framing, electrical, plumbing, mechanical, concrete, roofing, and finish trades. You have one point of contact. We handle everything behind it.

As a general contractor we serve as prime contractor, managing all subcontractor relationships, paying sub invoices, and carrying full financial and operational responsibility for the project. As a construction manager we provide oversight, scheduling, and cost tracking billed separately for time and expertise only. We do not manage subcontractor payments in a construction management engagement. Both services are available depending on the structure of your project.

We specialize in tenant improvements for restaurants, fast food and quick service concepts, retail storefronts, medical and dental offices, professional services offices, and franchise buildouts. We manage the full scope from permit coordination and demolition through framing, MEP rough-in, finishes, and final inspection.

We have completed commercial construction and tenant improvement projects for national and regional brands including Buffalo Wild Wings, Dunkin Donuts, and TA Truck Stop. We understand the documentation, brand standards, and timeline requirements that come with franchise and national brand projects.

Timelines vary depending on project scope, permit jurisdiction, material lead times, and site conditions. A straightforward tenant improvement may take eight to sixteen weeks from permit approval. A ground-up commercial build typically runs six to eighteen months. We provide a detailed project schedule at the start of every engagement and communicate proactively throughout if anything changes.

We track costs against the approved budget throughout the build and flag variances before they become problems. We review change order requests carefully, provide transparent cost reporting, and work with owners to find solutions that protect the budget without compromising the project.

Yes. Stonebridge Developers holds a California contractor license and is fully bonded and insured for commercial construction work throughout the state. We carry the credentials and documentation required for commercial, retail, medical, and government projects.
