In short

Engineer insurance is built on professional liability (errors & omissions), the coverage for claims that a design error, faulty calculation, or professional oversight caused a client or third party a loss. Engineering carries some of the highest professional stakes of any office trade — a stamped drawing, a load calculation, or a specification that proves wrong can lead to a costly failure, rework, or a lawsuit naming the firm. Standard business policies exclude professional negligence, which is exactly the claim engineers face. Auto World is a licensed California broker (#6005606) that shops multiple commercial carriers for solo engineers and full firms.

What commercial auto insurance covers

Professional Liability / E&O (the core)

Defends and pays claims that a design error, miscalculation, faulty specification, or professional oversight caused a client or third party a financial loss or physical failure. The policy that responds when a project goes wrong and the firm's stamp is on the drawings.

General Liability (GL)

Third-party bodily injury and property damage — an injury at your office or, importantly for engineers, at a job site you're visiting for inspection or oversight. Required by most owner and general-contractor contracts; limits up to $2M/$4M.

Project-specific & higher limits

Larger public and commercial projects often demand E&O limits well above the firm's standing policy and proof before you can be retained. We can structure limits and certificates to the project's contract requirements.

Business Owners Policy (BOP)

Bundles office property — workstations, plotters, survey and testing equipment, project records — with general liability for a firm with a physical office.

Workers' Compensation

Required in California once you have employees, and especially relevant for engineers doing field inspections and site visits where injury exposure is real, not theoretical.

Hired & non-owned auto (HNOA)

Covers the firm's liability when engineers drive their own cars or rentals to job sites and inspections — a routine but often-missed exposure for site-visiting professionals.

Who needs it

Civil & structural engineers

Design and stamping work where a structural or load error has the highest consequence and draws the largest claims.

MEP engineers

Mechanical, electrical, and plumbing design firms whose systems must perform and meet code.

Geotechnical & environmental engineers

Soils, site, and environmental work where a flawed assessment can surface long after the report is delivered.

Solo & consulting engineers

Independent licensed engineers consulting or stamping under contract, where one project can carry an outsized exposure.

Multi-discipline engineering firms

Staffed firms needing higher E&O limits, GL, a BOP, and workers' comp across the whole operation.

Forensic & expert-witness engineers

Engineers giving professional opinions and testimony that others rely on and can later dispute.

Frequently asked questions

Why is professional liability so central for engineers?
Because the consequence of an engineering error is uniquely high. A design flaw, a miscalculation, or a faulty specification can lead to structural failure, costly rework, project delay, or third-party injury — and the firm whose engineer stamped the drawings gets named. E&O defends and pays those claims. General liability won't, because it excludes claims arising from your professional services, which is precisely the engineering work itself.
A project owner requires E&O at a limit higher than my current policy — what do I do?
This is common on larger public and commercial projects. We can raise your firm's standing limit or, where appropriate, look at project-specific coverage, then issue a certificate that satisfies the owner's or general contractor's contract before you're retained. Send us the insurance requirements from the contract and we'll match them.
Do I need general liability if I have professional liability?
Usually yes — they cover different things. E&O covers your professional errors; GL covers ordinary third-party injury and property damage, including at the job sites you visit for inspection and oversight. Most owner and general-contractor contracts require both, plus naming them as additional insured on the GL.
Do I need workers' comp for an engineering office?
If you have employees in California, yes — it's required regardless of headcount. It matters more than people assume for engineering firms because field inspections, site walks, and testing put staff in environments where injuries actually happen, not just at a desk.
How much does engineering firm insurance cost?
It varies significantly by discipline (structural and geotechnical carry more exposure than some others), your firm's revenue and project size, the E&O limit your contracts require, and your staff count. A solo consultant pays far less than a multi-discipline firm bidding public work. Because it ranges so widely, the only accurate number is a real quote — call or text (619) 363-4466 and we'll shop it.
