Engineering Firms in California
Find California engineering firms and companies — PE-licensed civil, structural, mechanical, electrical, telecom, environmental, and industrial engineering services across the state.
California engineering services, end to end
From coastal San Diego permitting to Bay Area structural retrofits and Central Valley industrial buildouts, California engineering firms deliver the calculations, drawings, and stamped submittals that move projects through local jurisdictions. Every discipline that requires a seal — civil, structural, mechanical, electrical — must be signed by a PE licensed by the California Board for Professional Engineers, Land Surveyors, and Geologists (BPELSG).
Use this hub to find California engineering consulting firms by city or discipline, browse verified PE records, and request matched proposals for your project.

Licensed Professional Engineers in California
How to verify California engineering credentials
Check the individual PE license
Search the engineer's name on the California BPELSG license lookup and confirm the license is active, in the right discipline (CE, SE, EE, ME, etc.), and unencumbered.
Confirm the firm's organization record
California requires firms offering engineering services to comply with BPELSG organization rules — verify the firm's business record and that a licensed PE is designated to be in responsible charge.
Ask which discipline stamps the drawings
Only a California-licensed PE in the right branch can stamp. For structural, confirm SE licensure when required by CBC for essential facilities and tall buildings.
Verify AHJ experience
LADBS, DSA, OSHPD/HCAI, SFPUC, LADWP, and Caltrans each have specific submittal conventions — recent projects with your AHJ shortens review cycles.
Check insurance and contracts
Professional liability (E&O) at project-appropriate limits, workers' comp, and a signed contract that assigns risk before stamped drawings issue.
FAQ
What does a California engineering firm do?
California engineering firms design, analyze, and stamp the construction documents for buildings, infrastructure, utility, and industrial projects. Work typically includes calculations, drawings, permit submittals, construction administration, and PE-sealed reports under California BPELSG rules.
How much do California engineering services cost?
Fees vary by discipline and project size. Residential structural stamps often run $1,500–$5,000, mid-size civil site plans $10k–$60k, and complex industrial or telecom projects are typically scoped hourly at $150–$280/hr for licensed PEs in California.
Are engineering consulting firms in California licensed by the state?
Yes. Individual engineers are licensed by the California Board for Professional Engineers, Land Surveyors, and Geologists (BPELSG). Firms offering civil, electrical, or mechanical services must have a licensed PE in responsible charge.
How do I find a CA engineer near me?
Use EngineerMint's California directory to filter PE-licensed engineers by city, discipline, and project type. Each profile links to verified board records.
What's the difference between an engineering firm and an engineering company in California?
The terms are used interchangeably. Both refer to a business that employs PE-licensed engineers to design, analyze, and stamp projects — the distinction (if any) is a client's own terminology, not a legal category.
Is California a practice-act or title-act state?
California is a practice-act state for civil, electrical, and mechanical engineering — only licensed PEs in those branches can offer those services. Other branches, like industrial or chemical, are title-act, restricting use of the title but not the practice.
