Contractor licensing thresholds, regulator routing, requirements, reciprocity, and license types for New Mexico’s centralized Construction Industries Division model.
New Mexico takes a centralized approach through the Construction Industries Division (CID). Virtually every aspect of commercial, residential, and public works construction is regulated at the state level, including general building, mechanical, plumbing, electrical, and gas work. Manufactured housing is separately regulated by HUD and the Manufactured Housing Division.
Always verify statutes, fees, and application details with the live regulator before making bidding, licensing, or legal decisions.
The fastest way to orient yourself in New Mexico is to know that nearly all construction requires a CID license, and the system is built around classification codes.

Contractors
Regulators
How do I get a contractor license in New Mexico, and which agency handles it?
Apply through the Construction Industries Division (CID) at the Regulation and Licensing Department, 2550 Cerrillos Road, 3rd Floor, Santa Fe. Your qualifying party must pass trade and business & law exams (75% minimum each) and demonstrate 2 or 4 years of experience depending on classification. A $10,000 consumer protection bond and workers’ compensation insurance are required. See Requirements.
Does New Mexico require separate licenses for mechanical, plumbing, electrical, and gas work?
Yes. Each requires its own CID classification: MM-1 (Plumbing), MM-2 (Natural Gas Fitting), MM-3 (HVAC), MM-4 (Heating, Cooling and Process Piping), EE-98 or ER-1 (Electrical), and LP classifications (LP Gas). MM-98 combines all mechanical. Journeyman certificates are also required. See Types of licenses.
Can a homeowner in New Mexico perform their own construction without a license?
Yes, with conditions. Homeowners building a residence for themselves may act as their own GC with a Homeowner Building Permit and inspections. However, electrical and plumbing homeowner permits require passing an exam. All HVAC, gas, and fire sprinkler work must still be done by licensed contractors. See Construction work regulated.
Where do I go to get licensed in New Mexico?
CID is the primary regulator at 2550 Cerrillos Road, Santa Fe, NM 87505. Phone: (505) 476-4700. Exams are administered by PSI Exam Services at 2820 Broadbent Parkway NE, Albuquerque. See Who regulates construction.
How much does it cost to get licensed?
Application fees are $30. Exam fees range from $65 to $250 depending on classification. Annual license fees range from $50 to $300. The $10,000 consumer protection bond is required for all licensees. See Requirements.
What bonding and insurance requirements apply?
All licensees must maintain a $10,000 consumer protection bond — failure to maintain it cancels the license. Workers’ compensation insurance is required. No financial screening is required beyond the bond. See Requirements.
Can I use my out-of-state license in New Mexico?
Reciprocity applies only to journeyman electricians through an 11-state group: Alaska, Arkansas, Colorado, Idaho, Montana, Nebraska, Oklahoma, South Dakota, Texas, Utah, and Wyoming. Members are mutually exempt from exam requirements. Contractor licenses have no reciprocal arrangements. See Reciprocal agreements.
Does New Mexico require a license for roofing work?
Yes. Roofing is classified as GS-21 under CID specialty classifications. A CID license with this classification is required. See Types of licenses.
What is the journeyman supervision ratio?
The ratio is 3:1 (non-journeyman to journeyman) for residential work and 2:1 for commercial work. Journeyman certificates require 16 hours of continuing education per 3-year renewal cycle. See Requirements.
Does New Mexico require a license for LP gas work?
Yes. LP gas work requires its own CID classification: LP-1 through LP-10 for various activities (wholesale, retail, installation, service). Each has separate exam fees and annual license fees. See Types of licenses and Requirements.
Does New Mexico regulate virtually all construction at the state level?
Yes. CID handles virtually all construction licensing including general building, electrical, mechanical, plumbing, and LP gas. Some local jurisdictions with CID-approved building departments handle permitting and inspections within their boundaries. Manufactured housing is separately regulated by HUD. See Construction work regulated.
How does New Mexico handle manufactured housing licensing?
Manufactured housing is separately regulated by HUD and the Manufactured Housing Division, not CID. This is the main exception to CID’s centralized authority. See Construction work regulated.
What is the homeowner exemption, and what does it cover?
Homeowners building for themselves are exempt from general licensing but must obtain a Homeowner Building Permit, inspections, and Certificate of Occupancy. Electrical and plumbing homeowner permits require passing an exam. HVAC, gas, and fire sprinkler work must still be done by licensed contractors. See Construction work regulated.
How does New Mexico's centralized model compare to other states?
New Mexico is one of the most centralized: a single agency (CID) handles nearly all construction licensing with a unified exam standard (75%), bond requirement ($10,000), and classification system. This is simpler than Alabama (8 boards) or Idaho (registration plus trade licensing). See Who regulates construction.
What classification codes does New Mexico use?
GA (asphalt/roads), GB (general building), GF (fixed works), GS (specialty), EE/ER (electrical), MM/MS (mechanical/plumbing), and LP (LP gas). The “-98” suffix denotes combined classifications requiring multiple exams. See Types of licenses.
What are the fees across classifications?
Application fees are $30. Exam fees range from $65 (per exam for combined classifications) to $250 (EE-98, GB-98). Annual license fees range from $50 to $300. Journeyman exam fees range from $68.88 to $206.64. See Requirements.
How does reciprocity work in New Mexico?
New Mexico belongs to an 11-state group for journeyman electricians. Members are mutually exempt from exam requirements. No reciprocity exists for contractor licenses or other journeyman classifications. See Reciprocal agreements.
What exam requirements exist across classifications?
All qualifying parties must pass trade and business & law exams at 75% minimum. The business & law exam may be substituted with a 20-hour approved course. Some combined classifications (GA-98, GF-98, MM-98, EE-98, GB-98) require multiple exams. See Requirements.
What are the renewal cycles?
All CID licenses renew on a 3-year cycle. Journeyman certificates require 16 hours of continuing education per renewal cycle. See Requirements.
Which local jurisdictions have separate permitting authority?
Some local jurisdictions with CID-approved building departments handle permitting and inspections within their boundaries. For example, the Village of Corrales assumed all permitting, plan review, and inspection responsibilities as of November 2020. Contact the local building department to confirm jurisdiction. See Who regulates construction.

Four things you need to confirm before you can treat New Mexico as “ready” for a bid or an application. If any of these are unclear, you are not ready yet.
Identify the classification code
Determine which CID classification applies: GA (asphalt/roads), GB (general building), GF (fixed works), GS (specialty), EE/ER (electrical), MM/MS (mechanical/plumbing), or LP (LP gas).
Confirm the homeowner exemption does not apply
Homeowners building for themselves are exempt from general licensing. Everyone else needs a CID license, a $10,000 consumer protection bond, and workers’ compensation insurance.
Route to CID or the correct local authority
CID is the primary regulator. Some local jurisdictions with CID-approved building departments handle permitting and inspections within their boundaries.
Confirm exams, experience, and fees
Confirm trade and business & law exam requirements (75% minimum), experience duration (2 or 4 years), and the fee schedule for your specific classification.
If you can identify classification code, bond status, regulator, and exam/experience requirements, you have the minimum package needed for a New Mexico readiness check.
New Mexico regulates virtually all construction at the state level. The key question is not whether a license is needed, but which CID classification code applies.
CID license required under EE or ER classifications
Mechanical and plumbing
CID license required under MM classifications
LP gas
CID license required under LP classifications
Manufactured housing
Regulated by HUD and Manufactured Housing Division
Homeowners building a residence for themselves, or acting as their own general contractor with licensed subcontractors, are exempt from general licensing. They must still obtain a Homeowner Building Permit, inspections, and Certificate of Occupancy. Homeowner permits for electrical and plumbing work require passing an exam. All HVAC, gas, and fire sprinkler work must be performed by licensed contractors regardless of homeowner status.
If you are trying to figure out where to start, expand the scenario that is closest to your situation.
Residential building project
Apply for a GB-2 (Residential Building) classification from CID. This includes work authorized by GS specialty classifications. You need a qualifying party with 2 or 4 years of experience, passing exam scores (75%), and a $10,000 consumer protection bond.
Commercial or industrial construction
Apply for a GB-98 (General Building) classification. This is the broadest general building license and includes GB-2, GF-5, GF-7, and all GS classifications. Multiple exams are required.
Electrical installation
Apply for ER-1 (Residential Wiring, up to 5000V) or EE-98 (Residential, Commercial, and Industrial Wiring, up to 5000V). EE-98 includes ER-1 and all ES specialty classifications. Journeyman electricians from the 11-state reciprocity group are exempt from exam requirements.
Mechanical, plumbing, or HVAC work
Apply for the appropriate MM classification: MM-1 (Plumbing), MM-2 (Natural Gas Fitting), MM-3 (HVAC), MM-4 (Heating, Cooling and Process Piping), or MM-98 (Combined Mechanical, requires MM-1 through MM-4).
Homeowner doing own construction
Homeowners building for themselves are exempt from general contractor licensing but must obtain a Homeowner Building Permit, inspections, and Certificate of Occupancy. Electrical and plumbing homeowner permits require passing an exam. HVAC, gas, and fire sprinkler work must still be done by licensed contractors.
New Mexico uses a centralized model. The Construction Industries Division (CID) is the primary regulator for virtually all construction. PSI Exam Services administers licensing exams on CID’s behalf.
