Written for landscapers and lawn care routes, grounds maintenance contractors, tree services and arborists, irrigation, hardscape and fencing installers, and landscape firms that sell snow and ice work, in any US state.
The short version
- List every service you sell or add.Spraying, patios and irrigation each move you beyond maintenance into work that many states, or your city or county, license separately.
- Check state and local licenses before you quote.Pesticides applied for pay usually need one, even general use. In California, jobs from $1,000 need a contractor license (As of Oct 2026).
- Call 811 before every dig.Allow your state's notice time, and ask the client about private lines like irrigation, lighting or gas to a grill. 811 does not mark them.
The jobs clients add on the spot are the ones that trip up lawn and landscape firms: spray the weeds in the beds while you are here, can you do the patio too, run a line to the new bed. Each of those moves you from maintenance into work that many states, or your city or county, license separately.
Pesticides: general use is not a free pass
Federal law splits products into general and restricted use, and restricted-use products may only be applied by or under a certified applicator. Most states go further and license any business and person applying any pesticide for hire, general or restricted use, with application records, continuing education and proof of insurance.
The label is the law
Applying a pesticide in a way that is inconsistent with its label is a violation of federal law.
FIFRA, 7 U.S.C. 136j(a)(2)(G)
- Texas: the Department of Agriculture licenses commercial applicators and, for lawns and ornamental plants, structural pest control businesses.
- California: the Department of Pesticide Regulation issues the Qualified Applicator License or Certificate and the Maintenance Gardener business license, and the county agricultural commissioner registers the business before work.
- Florida: a Lawn and Ornamental license, or the Limited Commercial Landscape Maintenance certificate for ornamental beds only, not lawns. Applying fertilizer commercially also needs a limited certification for urban landscape commercial fertilizer application, and many Florida counties and cities ban nitrogen and phosphorus fertilizer from June 1 to September 30. As of Oct 2026.
- New York: DEC commercial applicator certification and business registration, with lawn markers after applications and, in counties that opted in, 48-hour neighbor notification. As of Oct 2026.
Applying any pesticide for hire without the license is a violation, and drift onto a neighbor's roses becomes your claim, often excluded from general liability without a pesticide endorsement.
Installs: contractor and irrigation licenses
California contractor licensing from $1,000
An appropriately classified CSLB license, such as the C-27 landscaping classification, is required for jobs of $1,000 or more in labor, materials and all other items. Below that, only casual, minor or inconsequential work with no building permit and nobody employed to help is exempt, and a job cannot be split to evade licensing. An unlicensed contractor cannot sue to collect and may have to return what it was paid. As of Oct 2026.
Cal. Bus. and Prof. Code 7031 and 7048(a) to (c)
Texas, New York and Florida have no statewide landscape contractor license, but local and specialty rules can apply. New York City and several downstate counties, including Nassau, Suffolk, Westchester, Rockland and Putnam, license or register home improvement contractors, and that can reach patios, fences and landscaping. Texas requires a TCEQ licensed irrigator to design, install or repair irrigation systems, and most states and water utilities require a tested backflow assembly on any irrigation tie-in. As of Oct 2026.
Before you dig
Call 811 first
Call 811 before any digging. State one-call laws set the notice: Texas at least 48 hours excluding weekends and holidays, California at least 2 working days, Florida at least 2 full business days and New York at least 2 working days. As of Oct 2026.
Tex. Utilities Code sec. 251.151; Cal. Gov. Code sec. 4216.2; Fla. Stat. sec. 556.105; 16 NYCRR part 753
Check the city code as well before you quote a route: many cities ban gas leaf blowers or limit their hours, and many require a permit to remove trees above a stated trunk diameter. Watering-day schedules come from the local water district. In California, new small off-road engines, including mowers and leaf blowers, must be zero-emission from model year 2024 under CARB rules. As of Oct 2026.
811 does not mark private lines the owner put in, such as irrigation, lighting or gas to a grill. Ask the client, or hire a private locator, before the first spade goes in.
Asked in Greymill
The $60 spray: in California, spraying for pay needs the right Department of Pesticide Regulation license, even with general-use weed killer.
If it drifts onto a neighbor's roses, the claim is yours. General liability often excludes it unless you add a pesticide endorsement (an add-on to the policy).
The $2,800 patio: jobs of $1,000 or more need a state contractor license, such as the C-27 landscaping classification (As of Oct 2026).
Splitting it into smaller jobs doesn't get around that.
Unlicensed, you can't sue if they don't pay, and you may have to return what they paid.
Even once licensed: call 811 at least 2 working days before you dig (As of Oct 2026). Ask about irrigation or lighting lines too, because 811 does not mark private ones.
Happy to draft a friendly no to the extras for now.
