Getting a New Mexico contractor license is a process with a clear sequence. Do the steps in order, do not skip the paperwork, and you will get through it without surprises. Here is the full path, from figuring out whether you need a license to staying compliant after you have one.
This is an independent guide, not affiliated with the New Mexico Construction Industries Division, the Regulation and Licensing Department, PSI, or NASCLA. Licensing details change, so verify current requirements against the official publications before you act.
Step 1: Confirm you need a license
New Mexico law defines a contractor broadly: anyone who undertakes, offers to undertake by bid, or purports to have the capacity to undertake contracting work, personally or through others. That includes subcontractors, specialty contractors, and construction managers.
The practical dividing line is the $7,200 casual-work exemption. An individual working on one project at a time, with compensation of $7,200 or less per year in the aggregate, doing casual, minor, or inconsequential work such as handyman repairs, is exempt. But the exemption has conditions: the work cannot be electrical wiring, plumbing, or gas fitting; it cannot be part of a larger operation; the individual cannot advertise as a contractor; and an annual declaration must be filed with the Division. Treat this as an exemption with strings attached, not as a free pass. Other exemptions exist for owner-occupied single-family dwellings, farm and ranch owner work, short-term commercial repairs up to $5,000, and weatherization projects up to $2,000.
Be honest about where your business is going. If you plan to grow past handyman work, starting the licensing process early beats scrambling later. The penalties for unlicensed contracting are real: a misdemeanor with jail time and fines that scale with the work value, plus administrative penalties. Full requirements cover every exemption and what disqualifies you from them.
Step 2: Pick your classification
New Mexico licenses by classification, which is the scope of work the license covers. Classifications follow a letter scheme: the first letter is G (General Construction), E (Electrical), or M (Mechanical); the second letter is A (asphalt), B (building), F (fixed works), or S (specialties). So GB-98 is general building, EE-98 is electrical, MM-98 is mechanical.
A license authorizes contracting only within its classification scope. Out-of-scope work is a violation and grounds for discipline. Key limits to know: GB-2 (residential building) covers residences and apartment houses of not more than four family units. EE-98 covers electrical wiring at 5,000 volts nominal or less. ES-3 covers low-voltage special systems under 50 volts. The classifications post maps the whole scheme.
Pick the classification that matches the work you actually plan to do. Choosing wrong costs time, so confirm before you spend money on anything else.
Step 3: Line up your qualifying party
Every license needs a qualifying party (QP): the person whose experience and exam passage stand behind the license. The QP needs 4 years of practical or related trade experience within the 10 years immediately before application (the commission may reduce this, but not below 2 years). Technical training counts as half a year per year of training, capped at half the total requirement. QPs must be 18 or older.
The QP rules have teeth. On separation, both the licensee and the QP must notify the Division in writing within 30 days. No individual may qualify more than one entity (except a joint venture) unless there is at least 30% common ownership. Losing the QP automatically cancels the license: no new bids, no new work, and work in progress may continue no more than 120 days. A temporary QP provision exists for faultless separations, with 90 days to pass the exam. Sort this out before you apply, not after.
Step 4: Pass the exams, or take the course
Most applicants face two hurdles: a trade exam for the classification and the Business and Law exam. The Business and Law exam is 50 questions, 75% (38 correct) to pass, 130 minutes, open book, with a $68.88 fee. Trade veterans fail the law exam regularly when they assume field experience is enough. It is not. Study it as its own subject, check how hard the exam really is, and warm up with sample questions before you schedule.
But here is the point most guides skip: the exam is not the only route. NMSA 60-13-16(C) provides that an applicant may satisfy the business-and-law requirement with a certificate of completion from an approved business and law course offered by an accredited education institute, instead of the PSI exam. The course materials must be available in both English and Spanish. If test anxiety is your obstacle, compare the exam and the course before you commit.
Timing rules: both exams must be passed within 1 year of each other, and once eligible you must test within 6 months or reapply. Passing scores are valid 1 year.
Step 5: Arrange the bond and insurance
New Mexico requires a $10,000 license bond (proof of responsibility) underwritten by a corporate surety authorized in New Mexico, for both issuance and renewal. The bond money is used only to cure Division-certified code violations the licensee does not correct. Claims must be made within 2 years of final inspection or certificate of occupancy. If the bond lapses and is not replaced before the 40th day, the license is subject to revocation. The surety must give 30 days' written notice before canceling.
Workers' compensation is strict: every contractor engaged in contracting or licensed under the CILA must carry coverage regardless of the number of employees. The general 3-or-more-workers threshold does not apply to contractors. Failure to maintain coverage is a license-discipline ground, and the state can get a stop-work injunction until coverage is obtained.
Step 6: Submit the application
The application goes to the Construction Industries Division with your fees, exam results, bond, and supporting documents. Budget for the application fee ($36 per the current PSI packet), classification fees ($300 per major classification such as GB-98, or $150 for other single classifications, capped at $300 per category), and the QP certificate fee ($6). Fill the application out completely. Incomplete applications are one of the most common reasons licensing takes longer than it should. Costs in full and realistic timelines have their own posts.
Step 7: Stay compliant after you are licensed
Licenses run on a 3-year cycle in current Division practice, expiring on the last day of the issue month, and the bond must cover the entire period. Let it lapse and the license is suspended by operation of law. The late fee is $1.00 per day for the first 30 days, then twice the renewal fee. Miss the 3-month window and the license is canceled.
Know the rules that govern daily work: show the license number on written bids and permit applications (a $150 penalty for failure), give residential owners the required written disclosure ($500 to $1,500 penalty for failure), follow the 21-day prompt-pay clock, and know the lien deadlines cold.
Common mistakes that slow people down
- Treating the $7,200 exemption as a license threshold. It is an exemption with conditions, not a "license required above" line.
- Underestimating the law exam. Study business and law as its own subject, and tab your references.
- Ignoring the QP separation timelines. 30 days to notify, 120 days of wind-down. Know the rules before you need them.
- Letting the bond lapse. 40 days without a bond puts the license at risk of revocation.
- Missing the one-year exam pairing. Both exams must be passed within a year of each other.
What it costs and how long it takes
Budget for the $68.88 exam fee per exam, the $36 application fee, classification fees, the $10,000 bond premium, insurance, and any prep materials. Full cost details and realistic timelines are covered in their own posts. Most of the calendar time is exams, paperwork, and Division processing, not the application form itself.
