What a specialty contractor license covers, how it differs from a general license, and how nine states organize specialty classes, exams, bonds and qualifiers.
A specialty contractor license lets a person or company contract for one trade, such as electrical, plumbing, HVAC, roofing or painting, instead of running a whole building project. Each state issues its own, so the class you need, the experience you prove and the exams you sit depend on the board where the work is.
For the rules in every state, see how to get a contractor license in each state.
At a glance Who issues it: a state board or agency, trade by trade. California's CSLB lists 43 specialty (C) classifications. Experience: four years in the trade in California, Arizona and Florida; one year per class for South Carolina's residential specialty registration. Exams: Tennessee requires a 50 question Business and Law exam for every new license, with a 73 percent passing standard. Bonds: from $5,000 (South Carolina residential specialty) to $25,000 (California). Qualifier: most boards license the business through one named person, such as California's RME or RMO or Arizona's qualifying party.
What Is a Specialty Contractor License?
A specialty contractor license authorizes work in one specific trade. California's statute puts it simply: a specialty contractor's work requires special skill, and its principal business uses specialized building trades or crafts (B&P Code 7058). The license does not authorize general construction management or coordinating several unrelated trades on one project.
Common specialty trades include:
- Painting
- Electrical
- Plumbing
- HVAC and refrigeration
- Roofing
- Concrete and masonry
- Flooring and tile
- Drywall
- Landscaping
- Pool and spa
- Fencing
- Solar
- Fire alarm and fire sprinkler
- Sign installation
States label these classes differently. California issues Class C specialty licenses numbered by trade (C-10 electrical, C-33 painting, C-39 roofing), while its general contractors hold Class A (general engineering) or Class B (general building). Tennessee uses CE for electrical, CMC for mechanical and an S prefix for specialty classes. Arizona issues separate commercial, residential and dual licenses for each trade (A.R.S. 32-1102).
For a primer on the other side of the line, see what does a general contractor do.
Specialty Contractor vs General Contractor
A general contractor can oversee an entire project and hire specialty contractors as subcontractors. A specialty contractor performs work in its own trade and typically cannot run a project that spans unrelated trades. We cover the working relationship in general contractor vs subcontractor.
| Factor | Specialty license | General license |
|---|---|---|
| Scope | One trade or a defined phase of work | Whole projects across trades |
| Permits | Trade permits (electrical, plumbing, mechanical) | Usually the building permit |
| Hiring subs | Generally limited to its own trade | Can hire any licensed specialty sub |
| Typical experience | 2 to 4 years in the trade | 3 to 5 years of broad construction |
| Exam | Trade exam plus business and law, where required | Broad building exam plus business and law |
| Bond and cost | Often lower, not always | Often higher bonds and financial tests |
In some states a specialty contractor running a multi trade job is treated as unlicensed general contracting. The general exam spans framing, mechanical, electrical, plumbing and project management; the specialty exam tests one trade. Cost ranges are in how much does a contractor license cost.
Specialty Contractor Licensing by State
Classification systems vary state to state. Here is how nine active licensing states organize specialty trades, each row checked against the board or statute on September 26, 2026.
| State | Who licenses specialty trades | How specialty classes work | Board source |
|---|---|---|---|
| California | Contractors State License Board | 43 C classes, from C-2 to C-61 | CSLB classifications |
| Florida | CILB, plus the ECLB for electrical and alarm | Division II trades plus 21 specialty categories; certified or registered | Fla. Stat. 489.105 |
| Texas | TDLR, the plumbing board and the State Fire Marshal | Trade by trade; no state general contractor license | TDLR |
| North Carolina | Separate trade boards beside the GC board | Electrical: Limited, Intermediate, Unlimited and 7 special restricted | NCBEEC licensing |
| Georgia | Construction Industry Licensing Board | Five divisions: conditioned air, electrical, low voltage, plumbers, utility | Georgia SOS |
| Tennessee | Board for Licensing Contractors | CE, CMC, LMC and S classes, each with a monetary limit | Classification outline |
| Arizona | Registrar of Contractors | Specialty residential, commercial or dual license per trade | ROC classifications |
| South Carolina | Residential Builders Commission | Up to 3 residential specialty classes per registration | SC LLR |
| Connecticut | Department of Consumer Protection | Trade licenses for electrical, plumbing, heating and similar work | CT DCP |

California Specialty (C) Classifications
California's system is detailed: the CSLB lists 43 specialty (C) classifications, 42 numbered trades from C-2 to C-60 plus the C-61 Limited Specialty class with its own subcategories. Examples:
| Code | Classification |
|---|---|
| C-10 | Electrical |
| C-20 | Warm-Air Heating, Ventilating and Air-Conditioning |
| C-27 | Landscaping |
| C-29 | Masonry |
| C-33 | Painting and Decorating |
| C-36 | Plumbing |
| C-39 | Roofing |
| C-43 | Sheet Metal |
| C-46 | Solar |
| C-53 | Swimming Pool |
| C-54 | Ceramic and Mosaic Tile |
| C-61 | Limited Specialty |
The qualifier needs four years of journey level experience or higher in the class, and the board can credit up to three years of education or apprenticeship, with at least one year of practical work. Each exam runs 3 1/2 hours on a computer at a PSI center. The original application fee is $450, and the initial license fee is $200 for a sole owner or $350 for other entities.
The contractor bond is $25,000. California qualifies companies through Responsible Managing Employees (RMEs) and Responsible Managing Officers (RMOs); see our California qualifying agent guide.
Florida Specialty Contractor Licenses
Florida splits specialty contracting between the Construction Industry Licensing Board (CILB) and the Electrical Contractors' Licensing Board (ECLB). Chapter 489 puts roofing, sheet metal, Class A, B and C air conditioning, mechanical, pool and spa, plumbing, underground utility, solar and pollutant storage contractors in Division II.
The CILB also certifies 21 specialty categories under Rule 61G4-15.100, effective May 5, 2024. They include glass and glazing, gypsum drywall, several marine classes, window and door installation, and structural classes such as structural aluminum or screen enclosures. The ECLB licenses electrical contractors, alarm system contractors I and II, and specialty electrical categories such as residential electrical and sign work.
Florida also separates Registered contractors, who may work only in the local jurisdictions where they met competency rules, from Certified contractors, who may contract anywhere in the state. The experience rule in 489.111 is four years, with at least one year as a foreman, a set mix of foreman years and college credit, or a related four year degree plus one year of experience in the category.
See the Florida qualifying agent guide for how qualifiers serve specialty firms in Florida.
For the full list of the 21 categories and the ones people wrongly think were repealed, read our guide to Florida certified specialty contractor categories. Two Division II trades that overlap with specialty work have their own guides: Florida mechanical contractors and Florida gas line work.
Texas, North Carolina, Georgia and Tennessee
Texas
Texas does not issue a statewide general contractor license, and TDLR's list of regulated industries has no general contractor program. It regulates specific trades instead:
- Electrical, including sign electricians and electrical sign contractors (TDLR)
- Air conditioning and refrigeration contractors (TDLR)
- Plumbing (Texas State Board of Plumbing Examiners)
- Fire alarm and fire sprinkler (State Fire Marshal's Office)
- Elevators and escalators (TDLR)
- Mold assessment and remediation (TDLR)
TDLR states that non exempt electrical work must be performed through a licensed electrical contractor. See how to get a general contractor license in Texas for the broader picture.
North Carolina
North Carolina licenses general contractors under Chapter 87, Article 1, and gives the trades their own boards:
- Electrical contractors (Article 4)
- Plumbing, heating and fire sprinkler contractors, one board (Article 2)
- Refrigeration contractors (Article 5)
- Well contractors (Article 7A)
The electrical board issues 10 classifications. A Limited license covers a single project up to $60,000 at 600 volts or less, an Intermediate license covers up to $150,000, and an Unlimited license has no project cap. See how to get a general contractor license in North Carolina and the North Carolina qualifying agent guide.
Georgia
Georgia's specialty trades sit in the State Construction Industry Licensing Board, which has five divisions:
- Conditioned air contractors (HVAC)
- Electrical contractors
- Low voltage contractors
- Master and journeyman plumbers
- Utility contractors
Residential and general contractors are licensed by a separate board. See our Georgia qualifying agent guide.
Tennessee
Tennessee uses one Board for Licensing Contractors, and every license carries a classification and a monetary limit. The main trade classes are CE (electrical), CMC (mechanical, with CMC-A plumbing and CMC-C HVAC), LMC (masonry) and a long list of S specialty classes. A license is required at $25,000 or more, and electrical, mechanical, plumbing, HVAC and roofing subcontractors need one when their portion reaches $25,000.
Every new applicant passes the Business and Law exam, but S specialty classes need no trade exam. The application fee is $250. See the Tennessee qualifying agent guide.
Specialty Contractor License Requirements
While details vary, expect most of the following.
Experience
Most specialty licenses require 2 to 4 years of journey level experience in the trade, documented by employers or contracts. California, Arizona and Florida set four years; South Carolina's residential specialty registration asks for one year within the past five years for each class.
If you do not have the years on paper, your options are:
- Apply with related trade experience, where the board accepts it.
- Bring on a qualifying agent who holds the credential; see how to hire a qualifying agent and what a qualifying agent is.
- Pursue a journeyman path first, covered in how to get a contractor license without experience.
Trade Exam
Most states require a written exam covering the trade plus business and law. Trade exams typically run 70 to 150 questions, business and law exams 50 to 100, and passing scores typically sit at 70 to 75 percent. Tennessee's 2026 candidate bulletin shows where one state lands:
| Tennessee exam | Questions | Passing standard |
|---|---|---|
| Business and Law | 50 | 73 percent |
| CE Electrical | 100 | 73 percent |
| CMC-A Plumbing | 100 | 73 percent |
| CMC-C HVAC and Refrigeration | 100 | 73 percent |
| LMC Masonry | 70 | 73 percent |
Tennessee's exams are open book, cost $53 each through Prov, and are typically valid for two years.
Bond and Insurance
Specialty bonds typically range from $5,000 to $25,000 depending on state and trade. South Carolina requires a $5,000 bond for residential specialty work of $5,000 and over, and California requires $25,000. General liability and workers' compensation are common requirements, and the rules differ by state. See contractor bond requirements by state and contractor insurance requirements by state.
Financial Statement
Some states test finances as well as skill. Tennessee requires a CPA reviewed financial statement for monetary limits of $3,000,000 or less and an audited one above that. Its limit is 10 times the lesser of working capital or net worth, so a $150,000 limit needs $15,000 of each.
Since July 1, 2026, a Tennessee surety bond of at least 50 percent of the limit can stand in for the statement. Across states, net worth expectations run from $0 to $150,000 or more depending on the classification.
Background Check
Most states ask about criminal history. A conviction does not automatically disqualify you, but an undisclosed one can. If you have been denied for any reason, see contractor license application denied.
How Much Does a Specialty Contractor License Cost?
Total first year cost typically falls between $1,500 and $6,000, depending on state, bond premium, insurance and staffing. Treat the ranges below as planning numbers and check your board's own schedule.
| Cost item | Typical range | Board example |
|---|---|---|
| Application and exam fees | $250 to $800 | California $450 application; Tennessee $250 plus $53 per exam |
| Initial license fee | $100 to $500 | California $200 sole owner, $350 other entities |
| Bond premium | $100 to $500 a year | Premium depends on the bond amount and credit |
| General liability insurance | $500 to $2,000 a year | Set by the carrier |
| Workers' compensation | Depends on payroll | Set by the carrier |
| Renewal | $100 to $400 every 1 to 3 years | NC electrical $100 to $200 a year; California $450 to $700 |
California's renewal fees run above the typical range: $450 for an active sole owner license and $700 for other entities, or $300 and $500 while inactive.
How Long Does It Take to Get a Specialty Contractor License?
Faster than a general contractor license in most states. A typical range is 6 weeks to 4 months from start to finish.
| Stage | Typical time |
|---|---|
| Application paperwork and experience verification | 2 to 4 weeks |
| Board review and exam approval | 4 to 12 weeks |
| Exam scheduling and passing | 1 to 4 weeks |
| License issuance after passing | 1 to 3 weeks |
For deeper timeline analysis, see how long does it take to get a contractor license.
How to Get a Specialty Contractor License, Step by Step
- Identify your classification. Confirm the exact specialty code your work falls under in the target state.
- Check experience requirements. If you do not qualify yourself, identify a qualifying agent path.
- Form your business entity. An LLC or corporation, registered in the state.
- Bind insurance. General liability and workers' compensation at or above state and local minimums.
- Secure your surety bond. The premium depends on credit and the bond amount.
- Document your experience. Employer sign offs, contracts, W-2s and tax filings are common evidence.
- Apply and sit for exams. Most boards require a trade exam, a business and law exam, or both.
- Finish issuance. Passing is not the finish line: CSLB states that the pass report is not a license, and the license issues only after you answer the bond and fee letter.
If you would rather hand off the process, our consultation packages cover it from classification choice to issuance.
When a Specialty License Is the Wrong Choice
A specialty license fits a single trade business that can document trade experience. It is the wrong call when you routinely run remodels, additions or new construction across trades, bid as a prime on commercial or government work, or hire subs across trades. For those, see how to become a general contractor and how to get a general contractor license.
Operating Within Your Classification
A common violation for specialty contractors is working outside the scope of the license. A C-33 painter takes a job that includes stucco repair. A C-39 roofer self performs sheet metal work that calls for a C-43. A plumbing contractor runs a gas line without the right endorsement.
Boards take this seriously; see compliance errors that trigger state board investigations and working without a contractor license. If you keep needing scope you do not have, the answer is usually one of these:
- Subcontract the out of scope work to a properly licensed firm.
- Add a second classification. California charges $230 to add one to an existing license.
- Upgrade to a general contractor license.
- Bring in a qualifying agent for the added classification, covered in multi-jurisdiction licensure.
Multi-State Specialty Operations
There is no national specialty contractor license. You need a license in each state that requires one, and the classes rarely match one for one. Many expanding firms bring on a qualifying agent in each new state instead of relocating an owner.
For cross border strategy, see how to get a contractor license in another state and how commercial contractors enter new jurisdictions legally.
How a Qualifying Agent Fits a Specialty License
Most boards license the business through one named person who carries the exam and the experience. In California, the RME or RMO must exercise supervision and control of the company's construction operations under B&P 7068.1, and an RME files a $25,000 bond of qualifying individual. Arizona's qualifying party is responsible for the licensee's actions and must either hold an ownership interest in the license or be regularly employed by the licensee. Tennessee lets an owner, full time employee or officer sit the exams as the company's Qualifying Agent, and Florida's primary qualifying agent supervises and controls the firm's contracting activities.
So if your company does the work but the owner lacks the years or the exam, a credentialed W-2 employee who actually supervises the jobs can qualify it. The Licensing Company, led by industry authorities Marshall Schofield and Jeremiah Jaskulski, places that kind of qualifier nationwide. Start with how to hire a qualifying agent, read what a qualifying agent is, or see how qualifying agents help contractors expand. If you hold a trade credential yourself, become a qualifying agent in a full time W-2 role.
Frequently Asked Questions
What is a specialty license in construction?
It is a state license to contract in one trade, such as electrical, plumbing, HVAC or roofing, without managing a whole project. California calls these C classifications and lists 43 of them.
What is a specialty building contractor?
A contractor whose work is limited to one trade or phase of a building project. Florida's statute defines it as a contractor limited to a particular phase of construction in a category the board adopts by rule.
How do I get a specialty contractor license?
Confirm the classification, prove the experience (four years in California, Arizona and Florida), pass any required exams, post the bond and insurance, and apply. If your company lacks a qualified person, a qualifying agent can fill that role.
Does Florida have a specialty contractor license?
Yes. The CILB certifies Division II trades such as roofing, plumbing and air conditioning, plus 21 specialty categories under Rule 61G4-15.100, including structural aluminum or screen enclosures, structural steel work and glass and glazing. Electrical and alarm specialties go through the ECLB.
Can a specialty contractor act as a general contractor?
Generally no. Running a multi trade project on a specialty license can be treated as unlicensed general contracting, so look at a general license or a second classification.
Do I need a license for every trade I perform?
Often yes, once the work reaches the state's threshold. In Tennessee, electrical, mechanical, plumbing, HVAC and roofing subcontractors need a license when their portion reaches $25,000. Check do I need a contractor license for your state.
Does Connecticut license specialty trades?
Yes. The Department of Consumer Protection requires trade licenses for electrical, HVAC, plumbing, heating and similar work. Home improvement and new home construction contractors also register with the department.
Is there a national specialty contractor license?
No. Each state licenses its own trades, and Texas licenses trades without licensing general contractors at all. A firm working in several states needs a qualified person for each license.
