STATE LICENSE
ConditionalWyoming Department of Agriculture — Techn…
Mowing, planting, hardscape, and general landscape work need no state license in Wyoming. Two scopes do: WDA's Chapter 28 rules define a commercial application as applying any pesticide (other than sanitizers and disinfectants) by contract or hire and require a commercial applicator license before making one — for lawns and landscapes, Category 903 Ornamental and Turf Pest Control (weed, insect, disease, and rodent subcategories). Every for-hire application must be under the direct supervision of a certified commercial applicator (W.S. 35-7-376(b)).
Electrical work on sprinkler systems is also state-licensed: lawn sprinkler systems under 90 volts fall in the low voltage electrical contractor scope, and water well and irrigation wiring on the load side of the disconnect in the limited contractor scope (W.S. 35-9-123(a)(vii)(G), (viii)(D)); DFPES charges $200 for either contractor license, waived for a one-person shop. Landscaping is services to buildings and dwellings (NAICS 5617), which Wyoming treats as extrahazardous employment for workers' compensation.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Wyoming has no statewide license for this trade, so contractor licensing is local. Cities, towns, and counties that license contractors set their own classes, exams, and bonds, but W.S. 16-6-1101 requires each of them to recognize an active, good-standing license issued by another Wyoming jurisdiction when the contractor shows a passing International Code Council (or equivalent) exam — with no retesting, though the accepting jurisdiction may require its own proof of financial assurance. Building codes are enforced by municipalities and counties that have taken delegated authority from the State Fire Marshal (W.S. 35-9-121), and any electrical work stays with state-licensed electrical contractors (W.S. 35-9-123).
The local offices section below names the exact permit desk for every Wyoming county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Mowing and planting need no state license; applying any pesticide or herbicide for hire needs a WDA commercial applicator license first (WDA Ch. 28 § 3(a)).
Cities and counties may not adopt pesticide use, notification, or storage rules stricter than the state act (W.S. 35-7-374(c)).
Installing pumping equipment in a water well needs a state water well pump installation contractor license (W.S. 33-42-103(f)).

Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
A contractor, subcontractor, or materialman who does not send the preliminary notice within the time required loses the right to assert a construction lien.
An employer that does not apply for coverage is liable to the state for every award paid and reserved for an injured employee; unpaid premiums carry interest.
Installing electrical equipment without being, or employing, a licensed electrical contractor violates the electrical act.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.

Pending verification: Local contractor licensing classes, exams, bonds, and fees in Cheyenne / Laramie County, Casper, Gillette, and other Wyoming cities and counties (local programs, outside this state-level record) · 2024–2026 session laws were not reviewed bill by bill (the wyoleg.gov bill-information service timed out); statute text was read from the Title PDFs compiled May 8, 2026 · License fee ($25), term, and recertification figures come from the Chapter 28 rule text WDA posts on its statutes page; the current Secretary of State rules registry version was not retrieved and may differ · Exam fees, testing schedule, and whether WDA requires proof of liability insurance from resident commercial applicators (statute requires it only from nonresidents seeking reciprocity, W.S. 35-7-362) · How DFPES applies the low voltage license to plug-in sprinkler controllers versus hard-wired systems (W.S. 35-9-123(a)(vii)(G) names lawn sprinkler systems under 90 volts)
