Construction Licensing Guide

Construction Contractor Licensing — All 50 States

Q: Do I need a contractor license in Texas?

Texas has no statewide general contractor license requirement. However, specialty trades are licensed at the state level: electrical contractors are licensed through the Texas Department of Licensing and Regulation (TDLR), plumbing contractors are licensed through the Texas State Board of Plumbing Examiners, and HVAC contractors are licensed through TDLR. Some Texas cities have local contractor licensing requirements — Dallas, Houston, and San Antonio each have their own local licensing programs. Operating in Texas without required city or trade licenses is a violation of local ordinances and state specialty licensing laws.

Q: OSHA 10 vs OSHA 30 — which do I need?

OSHA 10-Hour Construction is a 1–2 day course covering basic hazard recognition for construction workers. Cost approximately $250. It is the industry-standard expectation for all construction workers on commercial sites. OSHA 30-Hour Construction is a 3–4 day course for supervisors, foremen, and managers covering more comprehensive safety management. Cost approximately $500–$700. Neither is federally required by OSHA itself — but New York, New Jersey, Massachusetts, and Connecticut have passed laws requiring OSHA 10 or 30 for workers on certain public projects. Many general contractors and project owners require OSHA 30 as a subcontractor prerequisite. When in doubt, the 30-Hour is worth the extra investment for anyone in a supervisory role.

Q: What are CDL requirements for construction equipment hauling?

Hauling construction equipment on public roads typically requires: CDL Class A for any combination vehicle over 26,001 lb GVWR with a towed trailer over 10,000 lb GVWR (most excavator and bulldozer transport setups). CDL Class B for a single vehicle over 26,001 lb GVWR (large dump trucks). No CDL required for vehicles under 26,001 lb GVWR towing trailers under 10,001 lb (small skid steers or mini excavators on light trailers may qualify). FMCSA regulations also apply to interstate commercial vehicle operations — USDOT number, drug testing program, and driver qualification files are required.

Q: What are aerial lift training requirements?

OSHA 29 CFR 1926.453 requires aerial lift operators to be trained before operating any aerial work platform. ANSI A92.22 is the industry-recognized standard and the basis for most training programs. Key points: training must be equipment-specific — certification on a scissor lift does NOT qualify an operator to use a boom lift or telehandler. Training must be renewed every 3 years or when an operator is observed operating unsafely. Training must cover pre-operation inspection, equipment controls, safe work practices, and rescue procedures. Many rental companies provide basic training at delivery — but this does not replace employer-provided training required by OSHA.

Q: What is a contractor bond?

A contractor license bond (also called a contractor surety bond) is required by most states as a condition of obtaining a contractor license. The bond protects the public — not the contractor — if the licensed contractor fails to complete work, violates licensing laws, or causes financial harm. Bond amounts for state GC licenses typically range from $5,000 to $25,000. Annual premium costs are 1–3% of the bond amount for good-credit contractors. For larger public projects, performance bonds (100% of contract value) and payment bonds (100% of contract value) are often required separately from the license bond.

Q: Can subcontractors work without a license?

In states with statewide contractor licensing, subcontractors performing licensed trade work must hold their own appropriate license — the general contractor's license does not cover unlicensed subs for their specialty work. In states like Texas with no GC license, specialty trade subs (electrical, plumbing, HVAC) still need their state trade licenses. The key test is whether the work being performed is regulated — if it is, the sub must be licensed for that work regardless of who hired them. Working as an unlicensed sub in a licensed state exposes both the sub and the GC to licensing violations, fines, and insurance coverage problems.

Q: Is there state reciprocity for contractor licenses?

Some states have reciprocity agreements that allow licensed contractors from one state to obtain a license in another without retaking all exams. For example, Louisiana, Mississippi, and Tennessee have reciprocity agreements for certain contractor license classes. The National Association of State Contractors Licensing Agencies (NASCLA) administers a standardized exam accepted by multiple states (including Arizona, Georgia, Louisiana, Mississippi, Nevada, North Carolina, South Carolina, Tennessee, Utah, and others), which simplifies multi-state licensing. However, reciprocity is not universal — California CSLB, Florida DBPR, and many other states do not offer full reciprocity. Always verify with the specific state licensing board.

NCCCO Crane Certification

NCCCO Crane Operator Certification — Complete Guide

OSHA 29 CFR 1926.1427 requires crane operators to be certified by an accredited testing organization on most construction sites. NCCCO (National Commission for the Certification of Crane Operators) is the dominant accredited certifier.

Certification Element	Details
OSHA Requirement	29 CFR 1926.1427 — required for crane operation on most construction sites
Written Exam — Core	100 multiple-choice questions on general crane safety, rigging, hand signals, and load charts
Written Exam — Specialty	Separate module by crane type: telescoping/telescopic boom, lattice boom crawler, lattice boom truck, tower crane, overhead/bridge crane, articulating crane
Practical Exam	Hands-on evaluation with actual crane — precision load placement, controlled swing, emergency stop procedures
Cost	$250–$450 for written + practical exams combined
Renewal	Every 5 years; continuing education required
Grandfathering	None — all operators need current certification (no grandfather exemptions)
State Additions	California, New York, Oregon add state-specific requirements beyond NCCCO

Crane Types Requiring Separate Certifications: Telescoping/telescopic boom cranes, lattice boom crawler cranes, lattice boom truck cranes, tower cranes, overhead/bridge cranes, articulating cranes. An operator certified for a telescoping boom crane is NOT automatically certified for a tower crane — each type requires its own specialty module. See our crane financing guide for equipment financing options.

OSHA Training

OSHA 10-Hour and 30-Hour Construction Training

Course	Duration	Cost	Who It's For	Legally Required?
OSHA 10-Hour Construction	1–2 days	~$250	All construction workers — entry-level minimum	Not federal — required by NY, NJ, MA, CT for public projects; expected by most GCs
OSHA 30-Hour Construction	3–4 days	~$500–$700	Supervisors, foremen, project managers	Not federal — required by many GCs as sub qualification; NY/NJ public projects

OSHA 10-Hour covers: fall protection, electrical safety, struck-by hazards, caught-in/between hazards, personal protective equipment, materials handling, and scaffolding basics. OSHA 30-Hour covers all OSHA 10 topics in greater depth plus: safety programs, job hazard analysis, recordkeeping, and management of hazardous materials.

Both courses are delivered by OSHA-authorized trainers. Completion earns a wallet card from the U.S. Department of Labor. Cards do not expire under federal OSHA rules — but many project owners require refreshers every 3–5 years as a contract condition.

Aerial Lifts

Aerial Lift Safety Training — ANSI A92.22

OSHA 29 CFR 1926.453 requires operators to be trained before using any aerial work platform. ANSI A92.22 is the industry-recognized standard covering mobile elevating work platforms (MEWPs), including scissor lifts, boom lifts, and articulating boom lifts.

Key ANSI A92.22 Requirements

Training must be equipment-specific — certification on a scissor lift does NOT cover boom lifts. Each machine type requires separate training.
Training must cover pre-operation inspection, equipment controls, safe work practices, load capacity, fall protection, and emergency/rescue procedures.
Training must be renewed every 3 years or when an operator is observed operating unsafely, involved in an incident, or returning from extended absence.
Employers must maintain training records including date, equipment type, and trainer credentials.
Operators who fall under OSHA's scaffold standard (29 CFR 1926.502) must also have fall protection training.

See our aerial lift financing guide and specialized lifting equipment financing for equipment financing options.

Environmental Permits

Environmental Permits for Construction Operations

Construction contractors often trigger environmental permit requirements that are separate from contractor licensing. Failing to obtain required environmental permits can result in project shutdowns, fines, and personal liability.

Permit Type	Trigger	Issuing Authority
Stormwater NPDES Permit	Land disturbance over 1 acre	EPA or delegated state agency — requires SWPPP (Stormwater Pollution Prevention Plan)
Erosion and Sediment Control	Any grading or land disturbance in most jurisdictions	Local county or state agency — plan approval required before breaking ground
Section 404/401 Permit	Any work in or near waters of the US, including wetlands	US Army Corps of Engineers (404) + State Water Quality (401)
Air Quality / Dust Control	Large earthmoving operations, demolition	State or local air quality management district
Federal Explosives License or Permit	Blasting/explosives use	ATF Federal Explosives License (FEL) — plus state explosives permit required in most states
Asbestos/Lead Abatement License	Renovation or demolition of pre-1980 structures	State EPA — separate certification for asbestos and lead work

Common Questions

Construction Contractor Licensing — FAQ

Do I need a contractor license in Texas?

Texas has no statewide general contractor license requirement. However, specialty trades are licensed at the state level: electrical contractors through TDLR, plumbing through the Texas State Board of Plumbing Examiners, and HVAC through TDLR. Some Texas cities have local contractor licensing requirements — Dallas, Houston, and San Antonio each have their own local programs. Also see our guide to starting an excavating business.

What are NCCCO certification requirements and cost?

NCCCO certification is required by OSHA 29 CFR 1926.1427 for crane operators on most construction sites. The exam consists of a Core written exam (100 multiple-choice questions) plus a Specialty module for the specific crane type, plus a practical hands-on exam with an actual crane. Cost: $250–$450 for written plus practical. Renewal: every 5 years with continuing education. Grandfathering: none — all operators need certification. See our crane financing guide for equipment information.

OSHA 10 vs OSHA 30 — which do I need?

OSHA 10-Hour is a 1–2 day course covering basic hazard recognition, approximately $250. OSHA 30-Hour is a 3–4 day course for supervisors and managers, approximately $500–$700. Neither is federally required — but New York, New Jersey, Massachusetts, and Connecticut require them for certain public projects. Many general contractors require OSHA 30 as a subcontractor prerequisite. For anyone in a supervisory role, the 30-Hour is worth the investment.

What are CDL requirements for construction equipment hauling?

CDL Class A is required for any combination vehicle over 26,001 lb GVWR with a towed trailer over 10,000 lb GVWR — this covers most excavator and bulldozer transport setups. CDL Class B covers single vehicles over 26,001 lb GVWR (large dump trucks). No CDL is required for vehicles under 26,001 lb GVWR towing trailers under 10,001 lb. FMCSA regulations also apply to interstate commercial vehicle operations including USDOT number registration, drug testing programs, and driver qualification files.

What are aerial lift training requirements?

OSHA 29 CFR 1926.453 requires aerial lift operators to be trained before operating. ANSI A92.22 is the industry standard. Training must be equipment-specific — certification on a scissor lift does NOT qualify an operator for a boom lift. Training must be renewed every 3 years or when an operator is observed operating unsafely. Employers must maintain training records. See our aerial lift financing guide for equipment options.

What is a contractor bond?

A contractor license bond protects the public — not the contractor — if the licensed contractor fails to complete work, violates licensing laws, or causes financial harm. Bond amounts for state GC licenses typically range from $5,000 to $25,000. Annual premium costs are 1–3% of the bond amount for good-credit contractors. For large public projects, performance bonds (100% of contract value) and payment bonds are also required. See the full licensing and bonding guide for details.

Can subcontractors work without a license?

In states with statewide contractor licensing, subcontractors performing licensed trade work must hold their own license. The general contractor's license does not cover unlicensed subs for specialty work. In states like Texas with no GC license, specialty trade subs (electrical, plumbing, HVAC) still need their state trade licenses. Working as an unlicensed sub in a licensed state exposes both the sub and the GC to licensing violations, fines, and insurance coverage problems.

Is there state reciprocity for contractor licenses?

Some states have reciprocity agreements — Louisiana, Mississippi, and Tennessee have agreements for certain license classes. The NASCLA standardized exam is accepted by multiple states including Arizona, Georgia, Louisiana, Mississippi, Nevada, North Carolina, South Carolina, Tennessee, and Utah, simplifying multi-state licensing. However, California CSLB, Florida DBPR, and many others do not offer full reciprocity. Always verify with the specific state licensing board before assuming reciprocity applies.
