Utah DOPL Contractor License Classifications
Plain-language guide to B100, R100, specialty contractor classifications, and how your license class affects insurance documents for a Utah contractor application.
Start here if you are looking at DOPL paperwork and trying to figure out what the classification codes mean before you submit your contractor application.
The short version
Your classification describes the work. Your insurance documents prove the setup.
Your DOPL classification describes the type of contractor work you are applying to perform. The classification can affect exams, experience, trade scope, and how an insurance carrier understands your risk.
The core insurance-document path is often similar across classifications: general liability certificate, business-name matching, and either workers comp insurance or a workers comp waiver depending on whether the business has employees.
GL
What proof of liability coverage does DOPL need?
Most contractor applicants need a general liability certificate that matches the application and current DOPL instructions.
WC
Workers comp policy or waiver?
The worker-status question is separate from the classification code. Employees, owner-workers, and subcontractors can change the review.
General classifications
Common Utah general contractor classifications
DOPL’s contractor application uses general classifications for broader contractor license types. These codes are not insurance products. They describe the work authority being requested. Insurance carriers still ask about the actual operations, payroll, subcontractors, vehicles, tools, jobs, and certificates.
E100General Engineering
Broad engineering-related contracting work.
Insurance notes
Project type and site exposure matter heavily. Be ready to explain grading, utilities, excavation, infrastructure, equipment, subcontractors, and whether work is residential, commercial, or public-sector.
B100General Building
Broad general building work.
Insurance notes
Often creates a broader underwriting conversation: project type, subcontractors, payroll, structural work, residential vs commercial work, and certificates for job owners.
R100Residential & Small Commercial
Residential and smaller commercial general contracting.
Insurance notes
Similar document path to B100, but usually narrower scope. Residential vs commercial work, remodel vs new construction, and subcontractor use still matter to carriers.
H100HVAC
Heating, ventilation, and air conditioning work.
Insurance notes
HVAC work may involve installation, service, commercial jobs, employees, vehicles, tools, and certificate requests. DOPL has specific H100 requirements that should be checked against current instructions.
E200General Electrical
Electrical contractor classification.
Insurance notes
Carrier appetite may differ by electrical work type, commercial work, residential work, payroll, and subcontractor use. Electrical classifications may require the qualifier to hold the trade’s master license.
E201Residential Electrical
Residential electrical classification.
Insurance notes
Residential focus may narrow the work description but does not remove certificate, business-name, or worker-status questions. Electrical classifications may require the qualifier to hold the trade’s master license.
P200General Plumbing
Plumbing contractor classification.
Insurance notes
Trade work, employees, vehicles, and certificate requirements should be reviewed together. Plumbing classifications may require the qualifier to hold the trade’s master license.
P201Residential Plumbing
Residential plumbing classification.
Insurance notes
Residential focus may change underwriting questions, but GL and workers comp or waiver review still matters. Plumbing classifications may require the qualifier to hold the trade’s master license.
Specialty classifications
Specialty trade classifications listed on the DOPL contractor application
DOPL also lists specialty trade classifications. Specialty contractors should verify the current DOPL classification list and the scope-of-practice rule before applying. The examples below explain how each code can affect the insurance conversation without replacing DOPL’s official scope definitions.
B200Modular Unit Installation Contractor
Modular unit setup or installation work.
Insurance notes
Clarify whether work includes foundations, placement, securing units, utility connections, transportation, subcontractors, and job-site certificates.
R101Residential/Small Commercial Non-Structural Remodel/Repair
Limited residential or small commercial non-structural remodel and repair work.
Insurance notes
Be precise about what is and is not structural. Carriers may ask about handyman work, remodel scope, subcontractors, tools, vehicles, and whether work crosses into licensed specialty trades.
R200Factory Built Housing Contractor
Factory-built housing contractor work.
Insurance notes
Clarify setup work, transportation exposure, site work, foundations, subcontractors, and certificate requirements.
S202Solar Photovoltaic Contractor
Solar photovoltaic installation or related solar work.
Insurance notes
Carriers may ask about roof work, electrical connections, subcontractors, commercial vs residential installations, height exposure, and whether electrical work is subcontracted or self-performed.
S220Carpentry & Flooring Contractor
Carpentry and flooring work.
Insurance notes
Clarify finish carpentry, framing, flooring materials, subcontractors, job-site certificates, and whether structural work is involved.
S230Masonry, Siding, Stucco, Glass, and Rain Gutter Contractor
Exterior and building-envelope trades such as masonry, siding, stucco, glass, and rain gutters.
Insurance notes
Carriers may ask about heights, scaffolding, exterior work, residential vs commercial projects, subcontractors, and whether glass work is incidental or central.
S260Asphalt & Concrete Contractor
Asphalt and concrete work.
Insurance notes
Flatwork, driveways, sidewalks, paving, structural concrete, foundations, demolition, equipment, payroll, and subcontractor use can be treated differently by carriers.
S270Drywall, Paint, and Plastering Contractor
Drywall, painting, and plastering work.
Insurance notes
Clarify interior vs exterior work, height exposure, spray application, subcontractors, commercial jobs, apartment work, and certificate requirements.
S280Roofing Contractor
Roofing contractor work.
Insurance notes
Roofing is often a distinct underwriting class. Carriers may ask about steep-slope vs flat roofing, commercial vs residential, hot tar, subcontractors, fall exposure, payroll, and prior claims.
S310Foundation, Excavation, and Demolition Contractor
Foundation, excavation, and demolition work.
Insurance notes
This code can create a very different insurance conversation than simple flatwork. Clarify excavation depth, demolition type, foundations, grading, equipment, subcontractors, and job-site controls.
S330Landscape & Recreation Contractor
Landscape and recreation-related contractor work.
Insurance notes
Clarify landscaping, hardscape, irrigation, snow work, retaining walls, playground or recreation work, equipment, vehicles, and subcontractors.
S354Radon Mitigation
Radon mitigation work.
Insurance notes
Carriers may ask about residential vs commercial mitigation, testing, installation work, professional exposure, subcontractors, and whether additional professional liability review is needed.
S370Fire Suppression Systems Contractor
Fire suppression systems work.
Insurance notes
This classification can involve special qualification requirements and higher underwriting scrutiny. Clarify sprinkler work, inspections, service, commercial buildings, subcontractors, and certificate requirements.
S410Boiler, Pipeline, Wastewater, and Water Conditioner Contractor
Boiler, pipeline, wastewater, and water conditioner work.
Insurance notes
Clarify the exact work performed, pressure systems, utilities, commercial vs residential jobs, subcontractors, and whether pollution or professional exposure should be reviewed.
S440Sign Installation Contractor
Sign installation work.
Insurance notes
Carriers may ask about height exposure, electrical sign work, cranes or lifts, commercial locations, subcontractors, vehicles, and certificates.
S510Elevator Contractor
Elevator contractor work.
Insurance notes
This can involve special qualification requirements and significant underwriting scrutiny. Clarify installation vs service, commercial buildings, subcontractors, and any required professional or specialty coverage review.
S700Limited Scope Contractor
A limited-scope classification requested for a specific scope of practice.
Insurance notes
The insurance review depends on the written scope. Carriers need a plain-language description of exactly what work will be performed and what work will be excluded.
What changes
The code matters, but the work behind the code matters more
The classification code is a useful starting point, but it is not the whole underwriting story. Two contractors with the same code can still look very different to DOPL, to an insurance carrier, and to a job owner asking for a certificate.
Work scope
The classification helps define what work the contractor is applying to perform.
Licensing requirements
Some classifications can involve different exams, trade qualifiers, experience, or application paths.
Insurance underwriting
Insurance carriers care less about the code by itself and more about the work behind it: residential vs commercial, subcontractors, payroll, heights, excavation, structural work, hot work, tools, vehicles, and prior claims.
Certificate wording
The classification does not replace the need for a clean certificate: correct business name, active policy dates, required limits, and DOPL certificate-holder details.
What stays similar
Most applicants still need to solve the same insurance-document questions
Many DOPL applicants eventually arrive at the same document questions. The classification tells DOPL what work you are applying to perform. The insurance documents show whether the business setup is ready for the application.
General liability certificate
Most contractor applicants need a current general liability certificate that matches the applicant name, policy dates, limits, and DOPL certificate-holder details.
Read the DOPL general liability certificate guideWorkers comp insurance
Businesses with employees, and some owner-worker situations, may need workers compensation insurance documentation as part of the contractor application path.
Read the Utah contractor workers comp guideNo employees / waiver
A no-employee applicant may need a Workers Compensation Coverage Waiver instead of a workers comp policy. Subcontractors and owner-workers can make this question less simple than it looks.
Read the workers comp waiver guidePre-license course
DOPL-approved contractor pre-license course providers
Some Utah contractor license applicants must complete a DOPL-approved pre-license course before applying. That licensing step is separate from the insurance-document path on this page: general liability certificates, workers comp insurance, and workers comp waivers.
DOPL publishes the current approved-provider list. Redoubt does not recommend, rank, partner with, or guarantee any course provider. Use the official DOPL sources below to confirm whether a pre-license course applies to your application and which providers are currently approved.

Separate from insurance documents
A pre-license course satisfies a DOPL licensing requirement. It is not a substitute for a general liability certificate, workers comp policy, or workers comp waiver. Those insurance documents are reviewed on a different part of the application path.

Common confusion
Questions applicants ask about DOPL classifications
Is B100 the same as a general contractor license?+
B100 is one of the general contractor classifications listed by DOPL. It is commonly associated with broad general building work, but the application still needs to satisfy DOPL’s current requirements.
Does the insurance requirement change if I apply for B100 instead of R100?+
The core document path may be similar: general liability certificate, business-name matching, and workers comp or waiver review. The underwriting conversation can be different because B100 and R100 may describe different scopes of work.
Do I need workers comp if I have no employees?+
A no-employee applicant may have a waiver path instead of a workers comp policy. The answer should be reviewed if there are owner-workers, helpers, subcontractors, or plans to hire.
Does using 1099 subcontractors mean I can use a workers comp waiver?+
Not automatically. A 1099 label does not answer every worker-status question. The setup should be reviewed before assuming the waiver path is available.
Can I get a DOPL certificate before my policy is active?+
Usually no. A certificate of insurance summarizes coverage that is already in force. If the policy is not bound yet, the next step is usually setting up the policy first.
What if I picked the wrong classification?+
The classification decision belongs with DOPL and the applicant. Redoubt can help with the insurance-document side, but DOPL makes the licensing decision.
