New Mexico Septic Contractor License Requirements (2026)
By Gabriel Giner, Editor · Source checked 2026-09-30
New Mexico requires professional septic work to be performed under the appropriate Construction Industries Division contractor classification. NMED identifies MM-1, MM-98, MS-1, and MS-3 among the relevant classifications, depending on scope. NMED administers the liquid-waste system permit process, which is separate from the contractor license. Advanced system design and homeowner installation also have distinct requirements.
Regulatory Body

Eligibility Requirements
This guide does not establish a minimum applicant age; confirm any age requirement with the issuing authority. Check the current application for identification and tax-number requirements. Use the current application for identification and address requirements; out-of-state work history does not itself authorize work here.
Good moral character
Complete the disclosures required by the applicable application. No additional character standard is inferred from a permit or program summary.
Background investigation
Confirm any applicant screening with the issuing authority. The cited sources are not used to infer an unlisted fingerprint requirement.
Experience and Education
Match the proposed installation to a CID classification accepted for that work and obtain the corresponding contractor qualification. Submit the liquid-waste permit application and required design to NMED before construction.
Accepted proof of experience or eligibility
- Current application for the credential or local authorization described above.
- Supporting qualification records required by that application; retain approvals for the actual work scope.
Exam Requirements
The examination requirement has not been established in this record. Confirm it with the authority before applying. Provider or process notes: New Mexico Environment Department / Construction Industries Division
Examination fee: No complete current examination charge is established here; confirm the applicable assessment and provider.
CID qualifications and examinations depend on the selected contractor classification. The NMED permit page is not a substitute for the classification-specific licensing application or examination instructions.
Insurance and Bonds
No single applicable bond amount is established in this guide. Confirm the business, credential, and project requirements; an unspecified amount is not a bond exemption.
General liability
Confirm the current insurance documentation and coverage required for the actual credential, employer, and locality. No unverified coverage minimum is quoted here.
Workers' compensation
Confirm employee coverage obligations separately; the septic program sources do not establish a workers’ compensation exemption.
Fee Schedule
The reviewed sources do not establish a complete current fee schedule for this pathway. Obtain the current application and renewal amounts from the issuing authority. Local project charges, training, insurance, and business costs are separate; unspecified amounts are not zero-cost exemptions.

Out-of-state credentials must be considered under the septic program’s own rules. The pathways documented below do not establish NASCLA examination credit.

Do not assume an outside installer credential transfers automatically. Ask the issuing authority to evaluate it under the named pathway; any credit or exemption must be confirmed before relying on it.

Step-by-Step Application Roadmap
- Identify the applicable installer pathway. The homeowner allowance is limited to the owner’s personal residence under NMED’s conditions. It does not permit rental-property installations or hiring an unlicensed person to do the work.
- Prepare the qualification records. Match the proposed installation to a CID classification accepted for that work and obtain the corresponding contractor qualification. Submit the liquid-waste permit application and required design to NMED before construction.
- Complete the applicable assessment and filing. CID qualifications and examinations depend on the selected contractor classification. The NMED permit page is not a substitute for the classification-specific licensing application or examination instructions.
- Obtain the project approvals. Identify the permitting authority for the property, secure the required approved plans and construction authorization, and arrange inspections before covering the work. Keep the occupational credential separate from the site approval.
- Track the applicable renewal requirements. Keep the actual CID contractor license current. Maintain any system-specific qualifications and satisfy the individual permit conditions; a liquid-waste permit application fee is not the contractor’s renewal price.
