STATE LICENSE

Mowing, planting, and hardscape require no New York State trade credential. The state trigger is chemicals: offering pesticide or herbicide application for hire requires a DEC pesticide business registration ($900, three years, $1M liability) and a certified applicator or technician in Category 3A (Ornamentals, Shade Trees & Turf) or 3B (Turf).
Landscaping is expressly 'home improvement' under GBL § 770, so residential landscaping contracts over $500 need a GBL § 771 written contract statewide — and in New York City, DCWP lists landscaping, patios, fences, and terraces among the work requiring a Home Improvement Contractor license for residential jobs over $200.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
New York has no state license for this trade, so the local layer decides everything. New York City is the heaviest: DCWP licenses home improvement contractors (residential work over $200), DOB licenses master plumbers, master fire suppression piping contractors, master and special electricians and oil burner installers, registers general contractors for 1–3 family New Building permits, and requires 40-hour Site Safety Training cards on larger sites. Upstate, Buffalo licenses contractors through its Office of Licenses and runs plumbing and electrical licensing; Rochester only accepts electrical and plumbing permits from licensed tradespeople or single-family owner-occupants; Syracuse licenses electricians and HVAC/mechanical contractors while plumbing permits run through Onondaga County. Statewide, GBL Article 36-A governs every residential contract and WCL § 57 blocks permits without workers' comp proof.

Violating ECL Article 33 registration or certification requirements.
