Design-Build vs. General Contractor: What's the Difference?

"Design-build" and "general contractor" get compared constantly, but they are not quite the same kind of thing. A general contractor is a licensed role — in California, a contractor licensed by the Contractors State License Board to build. Design-build is a way of organizing a project: one company is responsible for both the design and the construction, under one agreement. Most design-build firms are themselves licensed general contractors. So the real question is not "design-build or general contractor?" but do you want one company responsible for the design and the building, or a separate designer and a separate builder?

A note on bias: UpFront Remodeling is a design-build general contractor, so we have a point of view. Most of what is written online about this topic comes from firms that sell one model or the other, which is worth keeping in mind. The goal here is to explain how each works so you can judge fairly.

The two common ways to organize a remodel

Design-build

You hire one firm, under one agreement, to design and build the project. One company is accountable for both, you have one point of contact, and because the builder is involved while the design is still taking shape, budget and schedule feedback can come early. The design and construction phases can also overlap, so some work can begin while other details are being finished.

Design-bid-build (architect or designer first)

You hire an architect or designer first. They produce the drawings, and then the drawings are put out to bid with general contractors. This gives you the most control over who designs and who builds, and bids from several contractors let you compare construction prices. The trade-offs are that you are managing the handoff between two separate parties, and that the construction price is not truly known until the design is finished — so it is possible to complete the drawings and then find the bids come in over budget.

A common variation is to hire a contractor to build from plans you already have, or that you commissioned separately. That works well when the plans are complete and the contractor agrees with them, but if the design and the real-world cost do not line up, the gap between the two parties is yours to resolve.

Side by side

• Who you hire: design-build is one firm; design-bid-build is a designer plus a separate contractor.
• Accountability: design-build puts design and construction under one company; with separate parties, a problem can become a question of whose it is.
• When you know the price: design-build tends to give budget feedback during design; design-bid-build typically fixes the construction price only after the drawings are complete and bid.
• Design control: design-bid-build gives you an independent designer and the most say over who designs and who builds; with design-build, you are choosing a firm whose design approach you need to like.
• Competitive pricing: design-bid-build lets you compare several construction bids; design-build usually means choosing one firm up front.
• Schedule: design-build phases can overlap; a bid process adds a step.

When each tends to fit

Design-build tends to suit homeowners who want one point of accountability, early cost feedback, and a simpler process — which describes most kitchen, bathroom, ADU and addition projects. Design-bid-build tends to suit homeowners who want an independent architect directing the design, or who want to put finished drawings out to several contractors and compare prices. Neither is always better, and both can be done well or badly.

How we approach design-build at UpFront

We are a licensed general contractor (CSLB #1101426) and we run projects as design-build: we coordinate architectural design, structural engineering and the permitting process together with the construction, from initial concepts through final inspection, under one contract. Every estimate is free and itemized, so you can see where the money goes before anything is committed. You can read more about our company and credentials and see how a project runs with us.

Questions to ask any design-build firm

• Who prepares the drawings, and which parts are done by licensed architects or engineers?
• Is the design fee separate or included in the project price, and what happens to the plans if you decide not to build?
• How is the price set, and when does it become firm?
• Who pulls the permits and handles inspections?
• How are changes handled once work begins?
• Can you see finished projects like yours, and speak to the people who lived through them?

Check these before you sign, whichever model you choose

Confirm the contractor's license is active with the state, get a written contract, and know California's limit on down payments.
