How to get a contractor license in New Mexico
New Mexico requires a license from the Construction Industries Division (CID) of the Regulation and Licensing Department for construction work, and unlike most states there is no small-job dollar exemption to hide under. Licenses are issued to businesses backed by a certified qualifying party who proves experience and passes two exams: a trade exam and a business and law exam, each with an $87 exam fee. The GB-98 general building license, the workhorse classification, takes four years of experience including two on commercial work.

When a license is required
Effectively all construction work in New Mexico requires a CID license, with no general dollar threshold, so even small paid jobs fall under the law. The exemptions that exist are narrow and specific, so confirm with CID before assuming any job is exempt rather than after a complaint lands.
License classes in New Mexico
GB-98 General Building
The broad license for erecting, altering, repairing, or demolishing residential and commercial buildings. It requires four years of qualifying experience, at least two of them commercial, and an accredited construction degree can substitute for up to two years.
GB-2 Residential
A residential-scope general building license for contractors who stay out of commercial work, with a lighter experience requirement than GB-98. Confirm current scope details with CID.
Electrical and mechanical classifications
Electrical (EE) and mechanical/plumbing (MM) work carry their own CID classifications, each requiring certified journeymen and their own trade exams.
Specialty classifications
Dozens of narrower classifications cover roofing, concrete, drywall, and similar scopes, each with its own experience proof and trade exam.
What you need before you apply
- A certified qualifying party who owns the business or works for it and anchors the license
- Four years of qualifying experience for GB-98, including at least two years commercial, documented with a notarized work experience affidavit
- Pass the trade exam for your classification (75 percent to pass)
- Pass the New Mexico business and law exam (75 percent to pass); each exam costs $87
- Register the business with the state and provide the documents CID requires
- Meet CID's current bond and financial requirements, which you should confirm directly before applying
- Carry workers compensation coverage if you have employees
How to get licensed in New Mexico
- Choose the classification and qualifying party. Match the classification to the work you actually sell. The qualifying party's documented experience has to fit that classification, so decide both together.
- Document the experience. Complete the notarized work experience affidavit covering the required years. For GB-98 that means four years at a supervisory level, two of them commercial, or credit from an accredited construction degree.
- Pass both exams. Schedule the trade exam and the business and law exam through the testing vendor, at $87 per exam, and score at least 75 percent on each. New Mexico accepts the NASCLA commercial exam for the general building trade portion.
- File the license application with CID. Submit the application with exam results, experience affidavit, business registration, and whatever bond or financial documentation CID currently requires.
- Verify scope before the first permit. New Mexico enforces classification scope: a GB-98 cannot self-perform electrical, for example. Confirm what your license covers with CID before you pull permits or sub out work.
Reciprocity with other states
New Mexico accepts the NASCLA commercial exam for the general building trade exam, which spares multi-state contractors one test, and CID can waive certain exams for applicants licensed elsewhere with comparable requirements. The business and law exam and the New Mexico application itself are not waived, so licensing here is still a real process.
Working without a license
Unlicensed contracting in New Mexico is a misdemeanor, and the practical penalty is worse: courts will not enforce an unlicensed contractor's contract, so you cannot sue a customer who refuses to pay, and New Mexico case law has even allowed customers to claw back money already paid. CID also issues citations and can stop work on site.
Frequently asked questions
Is there a dollar amount under which no license is needed in New Mexico?
No meaningful one. New Mexico requires a CID license for construction work generally, without the handyman thresholds common in other states. A few narrow exemptions exist, but you should confirm any of them with the Construction Industries Division before taking paid work unlicensed.
How long does a New Mexico contractor license take?
Most of the calendar goes to documenting four years of experience and scheduling two exams. An applicant with clean paperwork and passed exams can typically get through CID review in a matter of weeks, so a realistic end-to-end estimate is one to three months.
What is a qualifying party?
The individual whose experience and exam results back the company's license. They must own the business or work for it, and if they leave, the company has a limited window to replace them before the license lapses. One person can qualify more than one classification if their experience supports it.
Does New Mexico accept the NASCLA exam?
Yes, for the trade portion of the general building classification. You still take New Mexico's business and law exam and complete the full CID application. If you plan to work across several NASCLA states, taking that exam once is the efficient path.
