Utah Specialty Contractor License Classifications

Utah specialty contractor classifications are DOPL license categories for contractors performing a specific trade or limited scope of work. Specialty codes often start with "S" and include classifications for carpentry, concrete, excavation, demolition, landscaping, roofing, and other trades.

Definition

What is a Utah specialty contractor license classification?

A specialty classification describes a specific trade or limited scope of contractor work. It is not the same as a general contractor classification, and the exact scope should be verified against current DOPL rules.

Specialty classifications can matter for underwriting because the work may involve concrete, excavation, roofing, demolition, landscaping, carpentry, height exposure, equipment, vehicles, or subcontractors.

S220

S220 license Utah: Carpentry and Flooring Contractor

S220 covers structural, non-structural, and finish carpentry; named installed products such as cabinets and garage doors; specified hard-surface flooring; and several less obvious operations. The dedicated guide resolves its deck, fence, metal-stud, flooring-exemption, and adjacent-trade boundaries.

Best starting point when

  • The work is structural or finish carpentry, millwork, named installed products, or S220 flooring.
  • The contract stays within a defined carpentry or flooring package rather than a broad building project.
  • Decks, fences, exempt floor coverings, and adjacent trade work have been separated from the S220 service list.

Probably not when

  • The customer is buying a deck, fence, guardrail, or handrail, which points first to S330.
  • The business only installs carpet or vinyl flooring, which the current rule lists as license-exempt.
  • The business manages the broader building project, where B100 or R100 may be the right starting point.
  • The work fits another trade classification better.

Insurance implications

For insurance, be ready to describe structural vs finish work, flooring material, tools, vehicles, subcontractors, commercial jobs, and certificate needs.

S220 classification decision guide
S260

S260 license Utah: Asphalt and Concrete Contractor

S260 is the specialty classification to review for asphalt and concrete work such as driveways, sidewalks, patios, slabs, and concrete flatwork. The scope also reaches sealcoating, striping, forms, and reinforcing bar, so the dedicated guide is the better starting point for a real classification decision.

Best starting point when

  • The work is driveways, sidewalks, slabs, patios, asphalt, or concrete flatwork.
  • The work description is mostly asphalt or concrete rather than broad building work.
  • Foundation, excavation, and demolition are not the dominant exposure.

Probably not when

  • Foundation, excavation, or demolition dominates the work.
  • Broad building work dominates the project.
  • The work is better described as landscaping/hardscape or another specialty trade.

Insurance implications

For insurance, separate flatwork from structural concrete, equipment, subcontractors, job-site COIs, concrete pumping if any, and commercial/residential split.

S260 classification decision guideConcrete contractor insurance
S310

S310 license Utah: Foundation, Excavation, and Demolition Contractor

S310 is the specialty classification to review when the work involves foundations, excavation, or demolition, not just ordinary concrete flatwork.

Best starting point when

  • The business digs, grades, trenches, excavates, or prepares sites.
  • The business performs foundation work.
  • The business performs demolition or removal of structures.
  • The work may involve utilities, heavy equipment, structural risk, or job-site controls.

Probably not when

  • The business only pours driveways, patios, sidewalks, or slabs with no foundation/excavation/demolition exposure.
  • The work is landscaping/hardscape rather than foundation/excavation/demo.
  • The work is a general building project where B100/R100 is the better starting point.

Insurance implications

This code can move the insurance conversation from ordinary contractor GL into excavation, demolition, equipment, underground utilities, pollution, subcontractors, and site-safety controls. That is exactly why a flatwork contractor and a foundation/excavation/demo contractor should not be described the same way on an insurance submission.

S330

S330 license Utah: Landscape and Recreation Contractor

S330 is the specialty classification to review for landscaping, irrigation, hardscape, and recreation-feature work. Its scope changed on March 30, 2026 — swimming pool installation moved to B100 and R100, while factory-built spas stayed — so the dedicated guide is the better starting point for a real classification decision.

Best starting point when

  • The work is grading and planting for horticultural or decorative treatment.
  • The work is irrigation, hardscape, fencing, or recreation features such as courts and playgrounds.
  • The project may include equipment, vehicles, job-site work, or subcontractors.
  • The work is not broad building construction.

Probably not when

  • The work is ordinary lawn maintenance only, which the current exemption list names by name.
  • The business installs swimming pools, which now require B100 or R100.
  • The work is general building.
  • The work is foundation, excavation, or demolition.

Insurance implications

For insurance, describe retaining walls, snow removal, hardscape, irrigation, equipment, vehicles, subcontractors, and the residential/commercial split.

S280

S280 license Utah: Roofing Contractor

S280 covers roofing materials used as waterproof, weatherproof, or watertight roof systems. The current scope also includes materials attached to the roof, roof conversions, skylights, certain insulation, and incidental roof-drain clamp-ring work. Electrical skylight connections must be performed by an E200 or E201 contractor.

Best starting point when

  • Roofing is the principal contracted trade.
  • The work involves shingles, tile, slate, shakes, membranes, coatings, or comparable roofing materials.
  • The package includes roof attachments, roof conversion, non-electrical skylights, or roofing-related insulation.
  • Any electrical skylight connection is separated and performed by the appropriate electrical contractor.

Probably not when

  • Gutters, drains, roof flashings, gravel stops, or metal ridges dominate the work; compare S230.
  • The principal work is solar-module installation; compare S202.
  • Structural framing or roof-deck reconstruction dominates; compare S220 or a general classification.
  • The business contracts for the broader building project; compare B100 or R100.

Insurance implications

For insurance, describe steep-slope versus low-slope work, tear-offs, torch-applied or other hot work, heights, cranes or lifts, occupied buildings, water-intrusion exposure, subcontractors, and residential/commercial mix.

S280 classification decision guideRoofing contractor insurance
S270

S270 license Utah: Drywall, Paint, and Plastering Contractor

S270 is broader than its short title suggests. It covers drywall and gypsum assemblies, lightweight metal and non-bearing partitions, ceiling tile and grid systems, specified insulation, stucco and plaster, and paint, stain, varnish, wax, and other coatings.

Best starting point when

  • The contracted package is drywall, gypsum board, wallboard assemblies, or finishing.
  • The work uses lightweight metal framing for non-bearing partitions.
  • The work includes ceiling tile, ceiling panels, or the supporting grid system.
  • Painting, coating, plastering, stucco, or specified insulation is the principal trade.

Probably not when

  • Structural metal studs or bearing walls are involved; compare S220.
  • Masonry, siding, glazing, gutters, tile, or shower pans dominate; compare S230.
  • The work is wallpaper hanging or interior decorating only, which the current rule lists as license-exempt.
  • The company contracts for an entire remodel rather than an S270 trade package; compare R101, B100, or R100.

Insurance implications

For insurance, describe interior versus exterior work, heights and scaffolding, spray application, overspray controls, solvents and coatings, occupied-building work, commercial jobs, subcontractors, and any lead, silica, or surface-preparation exposure.

Painting contractor insurance
S230

S230 license Utah: Masonry, Siding, Stucco, Glass, and Rain Gutter Contractor

S230 combines several exterior and finish trades. It covers siding, stucco, plaster, glass and glass-holding systems, gutters and drains, roof flashings and related metal roof-edge components, masonry and tile products, and shower pans.

Best starting point when

  • The principal work is brick, block, stone, masonry, tile, or similar installed products.
  • The package centers on siding, exterior stucco, glass, or glazing systems.
  • The business installs rain gutters, drains, roof flashings, gravel stops, or metal ridges.
  • The contracted work includes shower pans or tile-based assemblies.

Probably not when

  • Roofing membranes or the overall roof system dominate; compare S280.
  • Drywall, painting, ceilings, or lightweight non-bearing partitions dominate; compare S270.
  • Structural framing or carpentry dominates; compare S220.
  • The business only installs mirrors, which the current rule lists as license-exempt.
  • The business controls a broader remodel or building project rather than an S230 trade package.

Insurance implications

For insurance, describe masonry and silica exposure, scaffolding and height, glazing size and installation method, water-intrusion exposure, gutters and roof access, tile and shower work, hot work, subcontractors, and residential/commercial mix.

S202

S202 license Utah: Solar Photovoltaic Contractor

S202 covers fabricating, constructing, installing, or replacing photovoltaic modules and related components. It expressly excludes wiring, electrical connections, and wiring methods governed by the National Electrical Code. An S202 contractor may hire or subcontract an E200 or E201 contractor for electrical work within that contractor's scope.

Best starting point when

  • The principal contract is the physical installation or replacement of photovoltaic modules and related components.
  • National Electrical Code-governed wiring and connections are separated from the S202 work.
  • An E200 or E201 contractor performs the applicable electrical portion.
  • Any roofing repair or roof-system work is separately classified and assigned.

Probably not when

  • The business intends to perform the electrical wiring or interconnection itself; review E200 or E201.
  • Roofing membranes, roof replacement, or weatherproofing work dominates; compare S280.
  • The package includes broader electrical or general-building control.
  • The system is completely standalone and does not connect to premises wiring or the electrical utility, which the current rule lists as license-exempt.

Insurance implications

For insurance, describe roof height and slope, fall protection, lifting and panel handling, attachment methods, possible water intrusion, panel values, subcontracted electrical work, completed operations, commercial versus residential systems, and battery work separately if offered.

Compare E200 and E201 electrical contractor scopes
R101

R101 license Utah: Residential and Small Commercial Non-Structural Remodeling and Repair

R101 covers remodeling or repairing an existing residential or small-commercial structure, subject to two major limits: it cannot change footings, foundations, weight-bearing walls, or other bearing portions, and a project or related series of projects cannot exceed $50,000 including labor and materials. An R101 licensee may not hold another specialty classification.

Best starting point when

  • The work is remodeling or repairing an existing structure.
  • The entire scope is non-structural.
  • The project or related series of projects totals $50,000 or less, including labor and materials.
  • The business does not need to combine R101 with another specialty classification.

Probably not when

  • The contract includes footings, foundations, bearing walls, or other structural changes.
  • The project or related series exceeds $50,000.
  • The work is new construction or a broader building project.
  • The business needs R101 plus S220, S230, S270, S280, or another specialty classification.
  • A project is under $7,000 and may fall within Utah’s separate small-project exemption; that exemption has conditions and regulated-trade carve-outs that must be checked.

Insurance implications

For insurance, describe the types and sizes of remodels, confirmation that structural work is excluded, occupied-premises exposure, water damage, tools, subcontractors, residential/commercial split, and the largest anticipated contract.

Compare broader general classificationsSmall-job handyman insurance
S354

S354 license Utah: Radon Mitigation Contractor

S354 covers laying out, fabricating, and installing radon mitigation systems. The current scope excludes work on heat recovery ventilation or makeup-air components and excludes electrical work. An S354 contractor may hire an H100 contractor for the ventilation or makeup-air portion and an E200 or E201 contractor for electrical work within that contractor's scope.

Best starting point when

  • The principal contract is the layout, fabrication, or installation of a radon mitigation system.
  • Heat recovery ventilation and makeup-air work are separated and assigned to an H100 contractor when needed.
  • Electrical work is separated and assigned to an E200 or E201 contractor.
  • The service list distinguishes mitigation-system installation from broader HVAC, electrical, foundation, or remodel work.

Probably not when

  • Heat recovery ventilation, makeup air, or broader HVAC work is the principal contracted result; compare H100.
  • The business intends to perform electrical work under S354; compare E200 or E201.
  • Foundation repair, structural alteration, or a broader remodel dominates the project.
  • The work is radon measurement or testing only rather than installation of a mitigation system; verify the applicable non-contractor requirements separately.

Insurance implications

For insurance, describe slab drilling and penetrations, roof and wall terminations, fan and piping installation, occupied-home work, water-intrusion and structural-damage controls, subcontracted HVAC or electrical work, completed operations, and residential/commercial mix.

S410

S410 license Utah: Boiler, Pipeline, Wastewater, and Water Conditioner Contractor

S410 covers several connected industrial and utility scopes: transmission pipes, conduit, and cables; regulated storage-tank systems; power and hot-water heating boilers; water-conditioning connections; and sewer, septic, drainage, and sewage-disposal systems. It includes incidental excavation, boring, trenching, backfilling, concrete, and asphalt needed for that work, subject to separate backflow and natural-gas conditions.

Best starting point when

  • The work is station-to-station transmission of water, steam, regulated gases, chemicals, slurries, data or communications, geothermal, or solar thermal systems up to a plumbing-system interface.
  • The package involves regulated above-ground or below-ground storage tanks, piping, dispensing, monitoring, or related equipment.
  • The business installs covered power boilers, hot-water heating boilers, water-conditioning equipment, sewer lines, septic systems, drainage, or sewage-disposal plants.
  • Excavation, boring, trenching, backfilling, concrete, or asphalt is incidental to the S410 system rather than the separately contracted result.

Probably not when

  • In-building plumbing beyond the stated system interface or water-conditioner connection dominates; compare P200 or P201.
  • Broader HVAC installation or ordinary building mechanical work dominates; compare H100.
  • Natural-gas work will be performed without the required Certified Natural Gas Technician.
  • Backflow-preventer installation is offered without completing the current S410 backflow continuing-education condition.
  • Excavation, concrete, or asphalt is sold as a standalone service rather than incidental S410 work; compare S310 or S260.

Insurance implications

For insurance, separate boiler and pressure-vessel work, underground pipelines and utilities, tanks and dispensing systems, petroleum or chemical products, sewage and septic operations, trenching and boring, hot work, pollution and contamination exposure, heavy equipment, natural-gas work, subcontractors, and completed operations.

A note on S350 vs S354 searches

Keyword tools may show searches for "S350 license Utah." The current DOPL all-classifications application reviewed here lists S354 Radon Mitigation, not S350. If you searched S350, verify the current DOPL classification list before relying on that code.

Documents

What specialty contractor applicants should expect

DOPL's specialty contractor page says applicants should find the desired specialty classification, complete the pre-license course, obtain general liability documentation, register the business entity, obtain an EIN, and resolve the employee/no- employee workers comp path. Employees point to workers comp documentation and related registrations; no employees point to the Workers Compensation Coverage Waiver path.

Classification choice is separate from insurance paperwork, but the work description matters. Verify current DOPL instructions before relying on any certificate limit, then be ready to explain business-name matching, trade operations, employees, subcontractors, and certificate requests.

FAQ

Questions about Utah specialty contractor classifications

What is a Utah specialty contractor license?+

A Utah specialty contractor license classification is a DOPL category for a contractor performing a specific trade or limited scope of work rather than broad general contracting.

How many specialty classifications can I apply for?+

The specialty application PDF reviewed here allows applicants to select up to three specialty classifications, but says R101 may not be combined with another specialty classification. Verify current DOPL instructions before applying.

What is an S310 license in Utah?+

S310 is a Utah specialty contractor classification commonly associated with foundation, excavation, and demolition contractor work. Applicants should verify the exact scope against current DOPL instructions.

What is an S220 license in Utah?+

S220 is a Utah specialty contractor classification commonly associated with carpentry and flooring contractor work. The insurance review should describe the actual carpentry, flooring, structural, subcontractor, and job-site exposure.

What is the difference between S260 and S310?+

S260 is the asphalt and concrete path to review for work like driveways, sidewalks, slabs, patios, and flatwork. S310 is the foundation, excavation, and demolition path to review when digging, trenching, foundation work, structural risk, utilities, or demolition dominates.

What is an S330 license in Utah?+

S330 is the Utah specialty contractor classification titled Landscape and Recreation Contractor. It covers grading and planting for horticultural or decorative treatment, plus irrigation, retaining walls, pergolas, patios, decking, fencing, athletic courts and playgrounds, and factory-built spas. Swimming pool installation was removed from the scope effective March 30, 2026 and now requires B100 or R100.

What is the difference between a specialty contractor and general contractor?+

A specialty contractor classification usually focuses on a specific trade or limited scope. A general contractor classification is broader and may apply to building, residential/small commercial, engineering, HVAC, electrical, or plumbing paths.

Does a specialty contractor need general liability insurance?+

Utah contractor applicants generally need a current general liability certificate that satisfies DOPL instructions. The classification helps describe the work the policy must be reviewed against.

Does a specialty contractor need workers comp or a waiver?+

That depends on worker setup. Applicants with employees may need workers comp documentation, while no-employee applicants may need a Workers Compensation Coverage Waiver.

Why do I see S350 when DOPL lists S354?+

Keyword tools may show searches for S350 license Utah. The current DOPL all-classifications application reviewed here lists S354 Radon Mitigation, not S350. Verify the current DOPL classification list before relying on that code.
