Is Construction Arbitrage Legal in New Mexico?

Yes. Construction arbitrage is legal in New Mexico. Winning the prime contract, subcontracting the physical work to licensed subs, and keeping the margin in between is legal here - and it is how every properly run general contractor in the state operates. The compliance question is about the CID licence. Get that right and the model works the same as anywhere else.

Two things matter: which CID licence classification you need, and making sure every trade sub you use holds their own licence independently.

Is construction arbitrage legal in New Mexico - what the law says#

Construction arbitrage means you hold the prime contract, your subs do the physical work, and you keep the spread. Some people call it contractor arbitrage or construction dropservicing - same model, different names. The global legality answer covers why it is legal across every English-speaking market. The model is not in question anywhere. Subcontracting is how the construction industry has always worked at every scale. What is in question is whether you hold the right licence and your subs do too.

In New Mexico, licensing sits with the Construction Industries Division (CID), part of the Regulation and Licensing Department. The governing law is the Construction Industries Licensing Act, NMSA 1978 §§60-13-1 through 60-13-59. The CID has authority over nearly every category of construction in the state - general building, electrical, plumbing, mechanical, LP gas, elevator - and it enforces that authority actively.

The CID licence: what you need and which classification#

The CID licences contractors by classification. Your licence must cover the type of work you are taking on as prime. The two main general building classifications are:

GB-98 General Building Contractor - The broader licence. Covers residential and commercial construction of all types, plus the specialty classifications that fall within building work. The Qualifying Party behind a GB-98 must have four years of relevant experience (8,000 hours), with at least two years in commercial construction. This is the classification to hold if you want to take on commercial work, mixed projects, or any building beyond a four-unit residential.

GB-2 Residential Building Contractor - Covers homes and apartment buildings up to four family units. The Qualifying Party needs two years of relevant experience (4,000 hours). Narrower scope, lower experience requirement. If your model is purely residential at the small end, GB-2 may be enough - but if there is any chance you will take on commercial work, start with GB-98.

For specialty trade work - electrical, plumbing, HVAC, roofing - there are GS-series classifications. Those are for your subs to hold, not you as the general building prime.

The Qualifying Party and how the licence works#

Every CID licence is built around a Qualifying Party (QP). The QP is the individual whose verified experience and exam passes support the business's licence. The business entity holds the licence; the QP is the person responsible for the technical competence behind it.

You need at least one QP per classification. The QP documents their experience, passes the required exams, and keeps the licence in good standing. Exams are administered by PSI - a trade exam specific to the classification, plus a Business and Law exam. The pass score is 75%.

The licence is valid for three years and must be renewed. The $10,000 surety bond must stay in force for the entire licence period - it is a condition of both initial licensure and renewal under NMAC 14.6.3.8. That bond is for the state's benefit, not yours. Claims against it cover code violations caused by the licensee that are not corrected.

Application fees run $30 (non-refundable application fee) plus $6 per certificate and applicable classification fees, processed through PSI at public.psiexams.com. Verify current fees before filing - the fee schedule sits on the PSI site, not the RLD site.

Subcontractors: the rule that defines the model#

This is the critical piece for construction arbitrage operators in New Mexico.

The New Mexico Administrative Code is clear: any work subcontracted by a prime contractor must be performed by an entity validly licensed in the classification(s) covering that work. Your GB-98 does not extend to your subs. Every trade sub must independently hold a valid CID licence.

That means:

• Electrical subs hold a CID electrical classification (GS-9 or similar)
• Plumbing subs hold a CID plumbing classification
• HVAC subs hold the relevant mechanical classification
• Roofing subs hold a CID roofing classification where required

Verify each sub's licence on the CID's public lookup before they start a job. An unlicensed sub doing work on your prime contract is your compliance problem - not just theirs. The CID can halt the project and the unlicensed work sits on your record.

There is one additional note in the code: a GB-98 cannot bid as prime on a project where the major portion of the work falls under certain GA or GF classifications unless the licence covers those too. Know what your licence covers before you price a job.

Workers' comp: the one-employee rule for CID contractors#

New Mexico workers' compensation has a standard threshold for most businesses. Construction is different.

If your business holds a CID licence under the Construction Industries Licensing Act, the Workers' Compensation Administration treats you as a construction employer with a one-employee trigger. The moment you have a single employee on your books, you need workers' comp cover. The WCA can fine you up to $3,000 per violation for operating without required coverage.

The right-to-control test determines whether someone working on your jobs is an employee or a genuine independent contractor. The label on the contract does not settle it. How much control you exercise over how the work gets done is what matters.

For the subs themselves: get a certificate of insurance from every sub before they step on a job. If a sub does not carry their own WC cover and their worker is injured, the claim can work its way back to you as prime. Every job, every sub, every time - not once a year.

Penalties for unlicensed contracting#

NMSA 1978 §60-13-52 sets out the criminal penalties. The CID can halt your project and file a charge in Metropolitan or Magistrate Court:

• Work valued at $5,000 or less: Up to 90 days in county jail, a fine of $300 to $500, or both
• Work valued over $5,000: Up to six months in county jail, a fine of 10% of the contract value, or both

Beyond the criminal exposure: a conviction bars you from applying for a CID licence for one year. Unlicensed contracts in New Mexico are unenforceable - you cannot sue to collect if you were not properly licensed when you signed.

Do not bid on or accept construction work in New Mexico without a valid CID licence in the right classification.

Running construction arbitrage from outside New Mexico#

The CID does not require New Mexico residency. Out-of-state operators can hold a GB-98 or GB-2 and run the model remotely - the same way people run construction businesses from another country. The licence requirements, the bond, the insurance obligations, the sub-licence verification rule - all of it applies regardless of where you sit. Get the licence in place before you start quoting work.

What makes New Mexico different from most states#

A few things worth knowing before you start here:

• No dollar minimum in the statute. Most states have a threshold ($25k, $50k, $75k) below which you can work unlicensed. New Mexico's CILA covers any construction work for compensation. Check with the CID for any current administrative interpretation before treating any small job as exempt.
• The Qualifying Party model means the licence depends on one person's credentials. If your QP leaves the business, the licence status is at risk. Have a plan.
• GB-98 requires four years of experience with two in commercial. If your QP is coming from a residential background, they may not qualify for the broader classification without more time.
• The sub-licensing rule is explicit in the administrative code. New Mexico regulators can and do check.

The insurance picture covers what GL and WC cover you need alongside the CID licence. The model is legal in New Mexico. Hold the right classification, keep the bond and insurance current, and verify every sub's CID licence before they touch a job. That is the full compliance picture.
