What insurance does a structural engineer need?
Not all professions face the same risks. Below is a breakdown of every coverage type relevant to structural engineers — what each one covers, whether it's required, and what you should expect to pay in 2026.
Professional Liability (E&O)Required
$120–$300/mo
Core protection for structural engineers. Covers design errors, calculation mistakes, and structural failures attributed to your engineering work.
General LiabilityRequired
$30–$80/mo
Covers site visit injuries and property damage during inspections.
Commercial Auto
$30–$80/mo
Covers your vehicle during site visits and inspections.
Umbrella Liability
$40–$100/mo
Extra liability coverage above base limits — important given the potential scale of structural failure claims.

Frequently asked questions
How much professional liability do structural engineers need?
Most structural engineers carry $1M per claim minimum. Those working on large commercial projects, hospitals, or bridges typically carry $2M–$5M given the potential scale of structural failure claims.
Does PE licensure require professional liability insurance?
Most states don't legally mandate E&O for PE licensure, but virtually all engineering contracts require proof of professional liability insurance. Most engineering firms also require it as a condition of employment.
Am I covered for past projects if I change insurers?
Only if you purchase tail coverage (extended reporting period). Claims-made policies only cover claims reported while the policy is active — tail coverage extends this protection for past work.
How to get the best rate
The fastest way to find the lowest rate is to compare multiple carriers side by side. Most structural engineers can get quotes from 3–5 insurers in under 10 minutes and receive their certificate of insurance the same day.
