How to choose between them
- Check the license yourself. Where California or Orange County licenses this work, the licensing board's own lookup confirms a license number in a minute. Do it before you sign, not after.
- Get three bids on the same scope. Written down, split into labor, materials, allowances and anything structural. Most people compare a total against a total and end up choosing between two different projects.
- Ask what is not included. Permits, debris removal, fixture and finish allowances, and repairs after demolition are the four that turn a cheap bid into an average one.
- Never pay a large deposit up front. A deposit to order materials and hold a start date is normal. Half the total before anyone shows up is not.

Design-build firms in Orange County: common questions
Design-build or architect plus general contractor?
Design-build is faster and keeps cost in view while you design, because the builder is pricing as you go. Architect plus bid gives you competitive pricing and an advocate independent of the builder. Large custom projects often go the second route.
