Quick facts
- Three branches: A, B and C
- NRS 624.215(1) divides the contracting business into general engineering contracting, general building contracting and specialty contracting, and states that "General engineering contracting and general building contracting are mutually exclusive branches." NAC 624.140, 624.160 and 624.180 turn those into the classification A, classification B and combined classification AB licences the Board actually issues, with classification C covering the specialty trades.NRS Chapter 624: State Contractors’ Board (Nevada Legislature); NAC Chapter 624: Contractors (Nevada Administrative Code)
- A and B are mutually exclusive, and AB exists because of it
- NRS 624.215(1) closes with the sentence "General engineering contracting and general building contracting are mutually exclusive branches." NAC 624.180 creates the combined classification AB for people qualified in both, and limits it "to those applicants or licensees who can show a sufficient degree of experience and financial responsibility to support an unlimited license in both the A and B classifications."NRS Chapter 624: State Contractors’ Board (Nevada Legislature); NAC Chapter 624: Contractors (Nevada Administrative Code)
- Four trades are walled off from a general building licence
- NRS 624.215(3) provides that except as allowed by NRS 624.220(4), "a general building contractor shall not perform specialty contracting in plumbing, electrical, refrigeration and air-conditioning or fire protection without a license for the specialty." The same subsection adds that unless he or she holds the appropriate specialty licence, a general building contractor "may only contract to perform specialty contracting if he or she is a prime contractor on a project."NRS Chapter 624: State Contractors’ Board (Nevada Legislature)
- Every Nevada licence carries a dollar ceiling
- This is the Nevada feature out-of-state contractors miss. NRS 624.220(2) requires the Board to "limit the field and scope of the operations of a licensed contractor by establishing a monetary limit on a contractor’s license," and that limit "must be the maximum contract a licensed contractor may undertake on one or more construction contracts on a single construction site or subdivision site for a single client." NRS 624.220(3) lets you ask the Board to raise it, permanently or for one project, and a single-project request must reach the Board "at least 5 working days before" you bid and be approved before you bid.NRS Chapter 624: State Contractors’ Board (Nevada Legislature)
- Four years of experience inside the last fifteen
- NRS 624.260(6) requires each applicant to have had, "within the 15 years immediately preceding the filing of the application for licensure, at least 4 years of experience as a journeyman, foreman, supervising employee or contractor in the specific classification in which the applicant is applying." Accredited college or equivalent training "may be used to satisfy not more than 3 years" of it. The Board’s own requirements page states the same four-year and fifteen-year test and adds that four Certification of Work Experience Forms are required per qualifier.NRS Chapter 624: State Contractors’ Board (Nevada Legislature); Nevada State Contractors Board: License Requirements
What the three branches actually cover
NRS 624.215(2) defines a general engineering contractor as one "whose principal contracting business is in connection with fixed works, including irrigation, drainage, water supply, water power, flood control, harbors, railroads, highways, tunnels, airports and airways, sewers and sewage disposal systems, bridges, inland waterways, pipelines for transmission of petroleum and other liquid or gaseous substances, refineries, chemical plants and industrial plants requiring a specialized engineering knowledge and skill, power plants, piers and foundations and structures or work incidental thereto." NAC 624.140 grants that as classification A, and NAC 624.150 breaks it into subclassifications running A-1 airports and A-2 highways through A-3 dams and reservoirs and beyond.
NRS 624.215(3) defines a general building contractor as one whose principal business is "the construction or remodeling of buildings or structures for the support, shelter and enclosure of persons, animals, chattels or movable property of any kind, requiring in their construction the use of more than two unrelated building trades or crafts, upon which he or she is a prime contractor and where the construction or remodeling of a building is the primary purpose." Read the three conditions together: more than two unrelated trades, prime contractor status, and building as the primary purpose. Take away any one and it is not general building work. NAC 624.170 lists the classification B subclassifications, including B-1 premanufactured housing and B-2 residential and small commercial, which covers structures that "do not extend more than three stories above the ground and one story below the ground."
NRS 624.215(4) defines a specialty contractor in one sentence: one "whose operations as such are the performance of construction work requiring special skill and whose principal contracting business involves the use of specialized building trades or crafts." The detail is all in NAC. NAC 624.190 onward defines the C-series - C-1 plumbing and heating with subclassifications including C-1b fire sprinklers and C-1d plumbing, C-2 electrical, C-3 carpentry, maintenance and minor repairs, C-4 painting and decorating, C-5 concrete, C-15 roofing and siding, C-21 refrigeration and air-conditioning and many more. The Board describes classification C as "42 distinct subcontracting fields."
One exclusion sits inside the general building definition and is easy to miss: NRS 624.215(3) provides that "a person who is licensed pursuant to chapter 489 of NRS and who exclusively constructs or repairs mobile homes, manufactured homes or commercial coaches is not a general building contractor."

The prime contractor rule, and the one-of-each limit
Nevada builds its scope rules around who is prime. NRS 624.215(10) defines a prime contractor as a general engineering contractor, a general building contractor, or a specialty contractor who "enters into an oral or written agreement with an owner of a construction project or an agent of an owner to provide any work, materials or equipment" for which they are licensed. Note "oral or written" - a handshake with the owner makes you prime.
NRS 624.215(8) then requires that "each construction project must have one, but not more than one, prime contractor who is a licensed contractor and is responsible for the work, materials and equipment for the construction project," and excuses a project from having one only where the work or the person providing it is exempt under NRS 624.031.
The interaction between the two general branches is governed by a counting rule. NRS 624.215(5) lets a general engineering contractor acting as prime "hire not more than one general building contractor to provide any work, materials or equipment as specified in subsection 3 on a single construction project." NRS 624.215(6) lets a general building contractor contract to provide management and counselling services for a professional fee, but only if it holds "an active license in the same classifications and subclassifications that are required to be held by the prime contractor on the project," and it too may hire not more than one general building contractor. NRS 624.215(7) closes the loop: a single project is limited to not more than one general building contractor providing management and counselling for a fee, and not more than one providing the work.

How far a specialty contractor may stray, and how far a general builder may
Both directions are governed by NRS 624.220(4), and they are not symmetrical. Paragraph (a) permits "a specialty contractor from taking and executing a contract involving the use of two or more crafts or trades, if the performance of the work in the crafts or trades, other than in which the specialty contractor is licensed, is incidental and supplemental to the performance of work in the craft for which the specialty contractor is licensed." No dollar cap. The test is incidental and supplemental, judged against your own licensed craft.
Paragraph (b) is where a licensed contractor of any kind may work outside their classification, and it is capped hard: only "if the value of the work is less than $1,000, including labor and materials, and the work does not require a permit," and never where "the work is of a type performed by a plumbing, electrical, refrigeration or air-conditioning contractor." The permit condition is doing as much work as the dollar figure. Most things that need a permit are outside the allowance regardless of value.
NRS 624.220(5) adds a separate hard limit specific to one hazard: the Board must adopt regulations "establishing a specific limit on the amount of asbestos that a licensed contractor with a license that is not classified for the abatement or removal of asbestos may abate or remove" under subsection 4. Do not read the general $1,000 allowance as covering asbestos work.
The experience test enforces the classification boundary at the front door as well. NRS 624.260(6) requires four years of experience "in the specific classification in which the applicant is applying." Fifteen years of general building experience does not qualify you for a C-2 electrical licence, and the Board is not permitted to average it out.

Where the licence stops applying at all
NRS 624.031 is the exemption list, and it does more work in Nevada than the classification structure does for small operators. Subsection 5 exempts an owner building or improving a residential structure for their own occupancy and not intended for sale or lease, with a rebuttable presumption of intent to sell if the structure is sold, leased or offered within one year of completion, and with a requirement that the owner "must apply to the Board for the exemption." Subsection 10 does the same for an owner whose property is primarily an agricultural or farming enterprise.
Subsection 6 is the small-job exemption and the one most people mean when they say "handyman work." It reaches "any work to repair or maintain property the value of which is less than $1,000, including labor and materials," and then withdraws itself in five situations: where a building permit is required; where the work is of a type performed by a plumbing, electrical, refrigeration, heating or air-conditioning contractor; where it is of a type performed by a classification the Board prescribes as one that "significantly affects the health, safety and welfare of members of the general public"; where it is performed as part of a larger project "the value of which is $500 or more" or split into sub-$500 contracts "to evade the provisions of this chapter"; or where it is done by an existing licensee or their employee.
That fourth exception contains a genuine internal inconsistency in the statute as published, and we are not going to resolve it for you. The exemption applies below $1,000; the larger-project carve-out bites at $500 or more. On the face of the text a $900 repair that forms part of a $600 project is inside the exemption by value and outside it by project. Both figures appear in the same subsection. Read it as an instruction to stay well clear of the line rather than as a threshold to plan against.
The rest of NRS 624.031 removes: work by authorised representatives of federal, state or local government (subsection 1); certain 501(c)(3) weatherization arrangements (subsection 2); officers of a court acting within their office (subsection 3); public utility work incidental to its business (subsection 4); the sale or installation of a finished product that "is not fabricated into and does not become a permanent fixed part of the structure" (subsection 7); work on personal property (subsection 8); federally financed work on a federal site (subsection 9); and construction oversight services to a long-term recovery group in a declared emergency area (subsection 11).

The monetary limit is the Nevada rule that surprises people
Most states licence you and let the market decide how big a job you take. Nevada does not. NRS 624.220(2) requires the Board to set a monetary limit on every licence, and defines it as "the maximum contract a licensed contractor may undertake on one or more construction contracts on a single construction site or subdivision site for a single client." Read the definition again: it aggregates. Three separate contracts with the same client on the same site count together against the one number.
The limit is not arbitrary. NRS 624.220(2) says it "must be determined after consideration of the factors set forth in NRS 624.260 to 624.265, inclusive," which are experience, knowledge and financial responsibility. In practice that is why the Board’s requirements page ties the depth of financial statement it wants to the size of limit you are asking for: a self-prepared balance sheet with an affidavit current within six months for $25,000 or less, a compiled statement by an independent CPA current within six months for $25,001 to $499,999, a compiled statement with full disclosures for $500,000 to $999,999, and a reviewed or audited statement current within one year at $1,000,000 and above. It also requires a Bank Verification Form completed by your bank.
You can move the number. NRS 624.220(3) lets a licensee ask the Board in writing to increase the limit "either on a permanent basis or for a single construction project," with supporting documentation. The single-project route has a hard timing rule that catches people mid-bid: the request "must be submitted to the Board at least 5 working days before the date on which the licensed contractor intends to submit a bid for the project and must be approved by the Board before the submission of a bid." Five working days before you bid, not before you sign.
One narrow relief valve sits in NRS 624.220(4)(b): a licensed contractor may perform work outside their own classification "if the value of the work is less than $1,000, including labor and materials, and the work does not require a permit" - except that it may never be work "of a type performed by a plumbing, electrical, refrigeration or air-conditioning contractor." That is the licensed-contractor twin of the NRS 624.031(6) exemption, and it carries the same four trades carve-out.

Check the official page yourself before you file or sign
Nevada spreads contractor rules across three places that do not cross-reference each other: NRS Chapter 624 and NAC Chapter 624 at the Legislature, the Nevada State Contractors Board for the application mechanics, and the Secretary of State for the entity and the state business licence. The Legislature’s site is the most reliable of the three and publishes the full chapter text openly, so where this guide states a figure it is almost always the statute’s own words.
One access gap you should know about before you budget. The Nevada Secretary of State site is behind an Imperva bot filter that answers every request with a challenge document rather than the page, and the state business portal behaves the same way. We could not read either. Every entity and business-licence figure in this guide therefore comes from the statute that fixes it - NRS 76.100, NRS 76.130, NRS 86.263, NRS 86.272, NRS 86.561 - and no Secretary of State processing time, expedite option or practice note is stated anywhere here, because none could be verified. Confirm current filing mechanics in SilverFlume or by phoning the Secretary of State.
One timing gap as well. NRS 624.240 and NRS 624.283 each exist in two published versions, one "Effective through December 31, 2029" and one "Effective January 1, 2030," and they differ on whether the Board may waive renewal fees during a declared rural contractor shortage. If you are reading a citation to either section after that date, confirm which text is live.

Common questions
Can a Nevada general building contractor do their own electrical work?
No, other than in one very narrow case. NRS 624.215(3) says a general building contractor "shall not perform specialty contracting in plumbing, electrical, refrigeration and air-conditioning or fire protection without a license for the specialty," except as NRS 624.220(4) allows. And NRS 624.220(4)(b), which is that allowance, expressly excludes those trades: a licensed contractor may not perform out-of-classification work "if the work is of a type performed by a plumbing, electrical, refrigeration or air-conditioning contractor," even under the $1,000 no-permit ceiling. The route is to hold the specialty licence or to subcontract to someone who does.
Official sources: NRS Chapter 624: State Contractors’ Board (Nevada Legislature)
Can I hold both a general engineering and a general building licence in Nevada?
Yes, through the combined classification. NRS 624.215(1) makes general engineering and general building "mutually exclusive branches," which is why one licence cannot cover both. NAC 624.180 answers it: the Board "will grant a classification AB license in the branches of general building and general engineering to persons who are qualified to act as both general building (classification B) and general engineering (classification A) contractors," and limits it "to those applicants or licensees who can show a sufficient degree of experience and financial responsibility to support an unlimited license in both the A and B classifications."
Official sources: NRS Chapter 624: State Contractors’ Board (Nevada Legislature); NAC Chapter 624: Contractors (Nevada Administrative Code)
How small does a job have to be before no Nevada licence is needed?
Under $1,000 including labour and materials, with five exceptions that swallow most real work. NRS 624.031(6) sets the figure, then removes the exemption where a building permit is required, where the work is of a type performed by a plumbing, electrical, refrigeration, heating or air-conditioning contractor, where the classification is one the Board says significantly affects public health, safety and welfare, where the work is part of a larger project "the value of which is $500 or more" or is split into sub-$500 contracts to evade the chapter, or where it is done by an existing licensee or their employee. Note the statute uses $1,000 in the exemption and $500 in the larger-project carve-out; we cite both as published and do not reconcile them.
Official sources: NRS Chapter 624: State Contractors’ Board (Nevada Legislature)
Does my Nevada licence limit how big a contract I can sign?
Yes, and this is the rule out-of-state contractors most often miss. NRS 624.220(2) requires the Board to establish "a monetary limit on a contractor's license," defined as "the maximum contract a licensed contractor may undertake on one or more construction contracts on a single construction site or subdivision site for a single client." It aggregates across contracts with the same client on the same site. NRS 624.220(3) lets you apply to raise it permanently or for one project, and a single-project request must reach the Board "at least 5 working days before" you bid and be approved before the bid goes in.
