Which part of your project needs a license?
Start with the actual line items, not the crew's job title. The same yard can contain work with no contractor classification and work that must be covered by one.
No contractor license attaches to horticultural work itself. Drip work limited to existing lines belongs on the written scope.
Hire on the worksheet → MS-6 Sprinkler system — new, moved or repairedPotable-water sprinkler systems have their own classification, including trenching and backflow prevention devices.
See MS-6 in the full register → GS-4 Concrete walkways, driveways and slabsConcrete flatwork includes mixing, placing and finishing, with the preparation and formwork that go with it.
See GS-4 in the full register → GS-16 · GS-8 Built walls and major gradingMasonry and qualifying retaining walls fall under GS-16. Serious cut-and-fill and grading fall under GS-8 earthmoving.
See GS-16 and GS-8 →The four classifications that show up in yards
All four are defined in 14.6.6 NMAC, New Mexico's classification and scope rule.
Lawn sprinklers
Installing, altering, repairing or maintaining potable-water sprinkler systems, including trenching and backflow prevention devices. If a bid says “new zones” or “tie into your line,” ask whose MS-6 license covers it. Open MS-6 →
Concrete and flatwork
Mixing, placing and finishing concrete for walkways, driveways and pads, with the excavation and formwork that go with that work. Open GS-4 →
Earthmoving
Cutting, filling, grading and trenching. The practical concern is consequence: work that changes drainage and where water travels is not the same as spreading a little soil. Open GS-8 →
Masonry
Built walls in block, stone, brick or adobe, including freestanding walls six feet and higher and retaining walls from thirty-six inches. Open GS-16 →

The exception people half-remember
There is a real statutory exception, and it is narrower than word-of-mouth versions suggest. Under NMSA 1978 §60-13-3(D)(14), unlicensed casual work is lawful only when all of the conditions apply: one undertaking at a time, total compensation not exceeding $7,200 a year, work that is genuinely casual or minor, no sign or advertisement suggesting you contract, and a declaration filed annually with the state. The exception never extends to electrical wiring, plumbing or gas fitting. A crew doing yards full-time does not fit that narrow exception.
Check the number yourself
A license number on a truck or proposal is only the start. Use the New Mexico public contractor license register to confirm the record.
Three things to match
- Search the company or individual's name and open the matching record.
- Confirm the license is active.
- Confirm the classification covers the work on your written scope.
Now aim it at the project
The hiring worksheet gives every crew the same scope and a row for licensed work.
