How to Check a Contractor's License in New Mexico

New Mexico requires a license for virtually all contractors who perform construction work in the state. The Construction Industries Division (CID), part of the New Mexico Regulation and Licensing Department, handles licensing, enforcement, and complaints. Whether you're hiring a general contractor to build a new home or a specialty contractor to install HVAC, the person doing the work needs a CID-issued license.

This is good news for homeowners. Unlike states where licensing is optional or handled by a patchwork of local jurisdictions, New Mexico gives you a single state-level system to verify anyone doing construction work. This guide walks you through exactly how to use it, what the license classifications mean, and what to look for before you sign a contract.

How does New Mexico contractor licensing work?

New Mexico's Construction Industries Division (CID) requires a license for any contractor performing work exceeding the state's cost threshold. The system uses classification codes—such as GB-2, GB-98, and specialty trade codes—that define exactly what type of work a contractor is authorized to perform. Every licensee must also carry a surety bond and general liability insurance.

The CID requires a license for any person or company performing construction, alteration, repair, or demolition work in New Mexico when the total project cost (labor and materials) exceeds a threshold set by regulation. The system is organized around license types and classification codes that define what kind of work a contractor is authorized to perform.

Here is how the main license categories break down:

• GB-2 (General Building Contractor)— This is the standard general contractor license. A GB-2 holder can perform residential and commercial building construction. They can act as the prime contractor on a project, hire subcontractors, and manage the overall job. Most general contractors you encounter on residential projects will hold this classification.
• GB-98 (General Building, Any Height or Size)— This is the unrestricted general building license. A GB-98 holder can work on structures of any size, height, or complexity with no limitations. This classification typically requires more experience and a harder exam than GB-2. If your project is a large commercial build or multi-story structure, you want to see a GB-98.
• GF (General Engineering/Heavy Highway)— This classification covers infrastructure and heavy construction work like roads, bridges, utilities, and earthwork. Most homeowners will not encounter GF contractors, but they are relevant for large-scale site development or land improvement projects.
• Specialty trade classifications— CID issues dozens of specialty classifications for specific trades. Examples include EE-98 (electrical), MM-98 (mechanical/HVAC), PB-6 (plumbing), and many others covering roofing, concrete, painting, landscaping, fencing, fire suppression, and more. Each classification limits the contractor to that specific scope of work.

Every licensed contractor must also carry a surety bond and maintain general liability insurance. The bond amounts vary by license classification and project size limits, but the requirement itself is universal. This gives homeowners an extra layer of financial protection if something goes wrong.

How do I search the CID license verification tool?

Go to the CID license lookup page on the Regulation and Licensing Department's website and search by license number, business name, or individual name. A license number search is the fastest and most accurate method. Once you have results, check license status, classification codes, expiration date, and whether any complaints or disciplinary actions are on file.

The CID maintains an online license verification system where you can look up any contractor by name, license number, or business name. Navigate to the CID license lookup page on the Regulation and Licensing Department's website.

You can search using several methods:

• By license number— If the contractor has given you their license number (which they should), enter it directly. This is the fastest and most accurate search method.
• By business name— Enter the company name as it appears on their business card or proposal. Try variations if you do not get results — some businesses register under a slightly different name than what they use publicly.
• By individual name— You can search by the name of the qualifying party, which is the individual whose experience and exam results qualified the business for its license.

When you pull up a result, here is what to look at:

• License status— This must show as active and current. If the status shows expired, suspended, revoked, or inactive, the contractor is not legally authorized to perform work. Do not hire them regardless of what explanation they give you.
• Classification codes— Verify that the contractor holds the right classification for your project. A contractor with an EE-98 (electrical) license cannot legally perform plumbing work. A contractor with a GB-2 cannot take on projects that exceed the size limitations of that classification.
• Expiration date— CID licenses must be renewed periodically. A license that expires next week is technically valid today, but it could lapse mid-project. Make sure there is enough runway on the expiration to cover your project timeline.
• Bond and insurance status— The listing should show active bond and insurance information. If either has lapsed, the license may be functionally invalid even if the status still shows as active.
• Disciplinary actions or complaints— Check for any notes about complaints, violations, or enforcement actions. A single resolved complaint from years ago may not be a dealbreaker, but a pattern of issues is a clear warning sign.

If you cannot find a contractor in the system or want additional verification, you can contact CID directly at (505) 476-4700. They can confirm license status and answer questions about specific classifications.

What do New Mexico's contractor license classifications mean for my project?

New Mexico uses classification codes to define exactly what work each contractor is legally authorized to perform. GB-2 covers standard residential and commercial construction; GB-98 is the unrestricted version for larger or more complex builds. Specialty trades like electrical (EE-98), mechanical (MM-98), and plumbing (PB-6) each require their own separate classification.

Understanding New Mexico's classification system helps you match the right contractor to your job. Here is a practical breakdown of the most common classifications homeowners encounter:

• GB-2 vs. GB-98— Both are general building contractors, but GB-2 has project size and height limitations while GB-98 does not. For a typical single-family home build or renovation, a GB-2 is usually sufficient. For commercial work or large multi-unit residential projects, look for a GB-98.
• EE-98 (Electrical)— Required for electrical installation and repair work. This includes wiring, panel upgrades, fixture installation, and any work involving the electrical system. Only hire an EE-98 licensed contractor for electrical work.
• MM-98 (Mechanical)— Covers HVAC systems, including heating, ventilation, air conditioning, and refrigeration. If you are replacing a furnace or installing central air, this is the classification you need.
• PB-6 (Plumbing)— Required for plumbing installation, repair, and alteration. This covers water supply lines, drain lines, fixtures, and water heaters.
• Other common specialty codes— RG (roofing), CN (concrete), PT (painting), LN (landscaping), FN (fencing), and FS (fire suppression) are among the many specialty classifications. Each restricts the contractor to that specific type of work.

A general contractor with a GB-2 or GB-98 license can hire licensed subcontractors for specialty trade work. But those subcontractors must hold their own valid CID licenses for their respective trades. If your general contractor is using a plumbing sub, that sub needs a PB-6 license. Ask for the subcontractors' license numbers and verify them the same way you verified the general contractor.

What else should I check beyond the contractor's license?

A valid CID license is a necessary starting point, but it does not guarantee quality or adequate financial protection for your specific project. You should separately verify the contractor's general liability insurance (call the insurer directly to confirm it's active), workers' compensation coverage, bond amount, references, and that they will pull proper permits.

• Insurance coverage— CID requires general liability insurance, but policies can lapse between renewals. Ask the contractor for a current certificate of insurance and call the insurer to confirm the policy is active. Make sure the coverage amount is appropriate for the size of your project.
• Workers' compensation— New Mexico requires workers' comp for employers with three or more employees. If your contractor has a crew, ask for proof of coverage. Without it, you could face liability for injuries that happen on your property.
• Bond amount— CID requires surety bonds, but the minimum bond amount may not cover the full scope of your project. Ask the contractor what their bond amount is and whether it is sufficient for the work being proposed.
• References— Ask for three to five references on projects similar to yours in scope and budget. Call each reference and ask about quality, timeline, budget adherence, and how the contractor handled problems.
• Permits— Most construction work in New Mexico requires building permits from the local jurisdiction. A properly licensed contractor will handle permit applications as part of the job. If a contractor suggests skipping the permit process, walk away.

How do I file a complaint against a contractor in New Mexico?

File a complaint through the CID section of the Regulation and Licensing Department website. CID can investigate unlicensed contracting, substandard work, contract disputes, and code violations. It has authority to issue fines, suspend or revoke licenses, and order corrective work—enforcement powers that states without centralized licensing cannot offer.

If you have a dispute with a licensed contractor in New Mexico, CID has an enforcement process to handle complaints. You can file a complaint through the CID section of the Regulation and Licensing Department website. Complaints can involve unlicensed contracting, substandard work, contract disputes, or violations of construction codes.

CID investigates complaints and has the authority to issue fines, suspend or revoke licenses, and order corrective work. The process takes time, but it provides a formal mechanism that states without centralized licensing cannot offer. This is one of the real advantages of New Mexico's system — a licensed contractor has something at stake beyond just their reputation.

For issues involving unlicensed contractors, CID can also take action. Performing construction work without a license in New Mexico is a violation of the Construction Industries Licensing Act, and CID actively pursues enforcement against unlicensed operators.

The bottom line

New Mexico makes contractor verification relatively straightforward compared to many other states. The CID maintains a single statewide licensing system that covers general contractors and specialty trades alike. Before hiring anyone for construction work, search the CID license lookup to confirm the contractor holds an active license with the right classification for your project.

Check that the license status is active, the classification matches your scope of work, the expiration date extends past your project timeline, and there are no unresolved complaints or disciplinary actions. Then go one step further: verify insurance, confirm workers' comp coverage if applicable, check references, and make sure permits will be pulled. The license is the foundation, but the full picture is what protects you.
