Idaho Umbrella and Excess Liability Guide

Idaho’s Division of Occupational and Professional Licenses says registered general contractors must show at least $300,000 single-limit general liability that includes products and continued operations, plus workers’ compensation proof or an explanation why it is not required. An Idaho Transportation Department building-renovation contract dated May 2024 uses a higher combined CGL/umbrella limit and requires the contractor to keep the named project aggregate available. Treat the first as a registration rule and the second as one contract’s terms; neither establishes the limit for your job.

What Is Umbrella and Excess Liability Insurance?

Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. Read the national Umbrella and excess liability guide.

Idaho Umbrella and Excess Liability Insurance Requirements

Requirement	Details
Registered general contractor documentation	DOPL’s registration FAQ requires a certificate showing a general-liability policy that includes products and continued operations for the contractor’s construction operations with at least a $300,000 single limit, along with workers’ compensation evidence or a statement why it is not required. The cited FAQ describes general-contractor registration; do not extend this threshold to every trade or treat it as a recommended business limit. ¹
ITD building contract example (May 2024)	For its District 5 mechanic/supply-building window-replacement contract, ITD requires CGL and, if needed, umbrella with a combined $1 million each-occurrence limit and a project-specific aggregate, plus contract-specific auto and endorsement terms. This is one public-works agreement, not an Idaho-wide limit. ²

ITD building contract example (May 2024)

For its District 5 mechanic/supply-building window-replacement contract, ITD requires CGL and, if needed, umbrella with a combined $1 million each-occurrence limit and a project-specific aggregate, plus contract-specific auto and endorsement terms. This is one public-works agreement, not an Idaho-wide limit. ²

What to Watch for With Umbrella and Excess Liability in Idaho

The $300,000 rule is narrow
DOPL’s cited requirement is framed for registered general contractors; the statute and regulator page do not establish a blanket excess-insurance mandate for every Idaho business or contractor specialty. Confirm the contractor category and the license or registration rule that actually applies before treating this threshold as a legal minimum. ¹
A project aggregate can matter as much as the occurrence limit
The May 2024 ITD building contract says the CGL’s general aggregate applies separately to that project location. That protects the project’s stated aggregate availability under the contract, but it does not by itself show whether your separate umbrella aggregate is project-specific; ask for the endorsement at each layer named in your contract. ²
Keep completed work in the schedule review
Idaho’s contractor-registration documentation expressly includes products and continued operations. The ITD contract separately calls for completed-operations liability and requires qualifying claims-made coverage to continue or receive a two-year tail. For renovation or installation work, ask how long completed operations remain covered and whether the excess follows the same basis. ^1,²
Transporting hazardous waste changes the auto question
The ITD contract’s auto clause calls for pollution coverage equivalent to the cited pollution-broadened auto endorsement and an MCS-90 endorsement when hazardous waste will be hauled. If your project includes that transport, identify the hauling subcontractor and its auto/pollution evidence; a general umbrella limit does not establish those specific terms. ²

Providers With Idaho License Records

These providers publish a national listing for Umbrella and excess liability; the license records below name the licensed entities and roles. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Idaho. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

Specialty Program Group LLC
TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. ¹⁴

Vouch’s licenses page, effective January 16, 2025, lists producer licenses in all 50 states and DC. Its separate surplus-lines table includes Idaho number 870820, while a footnote says Georgia and Idaho do not issue agency-level surplus-lines licenses. Because those statements conflict for Idaho, this record keeps Idaho producer-only and does not treat the table number as established agency surplus-lines authority. The page is company-reported and does not establish product availability. ¹⁵

Surplus-Lines Tax and Stamping Office in Idaho

Reported tax rate. 1.5% of premium when Idaho is the home state for property and casualty coverage ^5,^6,⁸

Idaho’s surplus-lines tax is 1.5%. For property-and-casualty insurance other than workers’ compensation, if Idaho is the insured’s home state the full premium is taxed regardless of where covered risks are located; other lines follow the statutory allocation rule. Surplus-lines policies do not receive Idaho guaranty-association protection.

Questions to Ask Before You Buy Umbrella and Excess Liability in Idaho

Does DOPL classify this contractor as a general contractor subject to its $300,000 registration evidence rule, or does another trade-specific rule apply?
Does the written contract require CGL and umbrella combined, or separate limits, and what aggregate must stay available to the project?
Which policy must cover completed operations, for how long, and what tail or continuous-coverage option does the contract accept?
Will any contractor haul hazardous waste, and if so, which auto pollution and motor-carrier endorsements must be shown?

Umbrella and Excess Liability Insurance in Idaho: FAQ

Does Idaho require registered general contractors to buy a $300,000 umbrella?

DOPL’s FAQ asks for at least $300,000 single-limit general liability including products and continued operations. It does not state that this must be a separate umbrella policy; the project contract may add a higher combined primary/excess requirement. ^1,²

Does the 2024 ITD limit apply to every Idaho contractor?

No. The $1 million combined CGL/umbrella provision is in one ITD building-renovation contract. Use the current solicitation and signed agreement for your job, including any project-specific endorsements. ²
