How to start a lawn care business in Connecticut: sales tax, DEEP spray rules and neighbor notice

Connecticut sorts lawn care into two worlds. If you cut grass, edge and plow, the state mostly stays out of your way on licensing and focuses on sales tax. If you apply anything labeled as a pesticide, you enter a thick rulebook run by the Department of Energy and Environmental Protection (DEEP), with registration, signs, neighbor notice and five years of records. This page covers only what changes in Connecticut. For the national startup basics, use the core lawn care startup guide, and for filings and formation costs, see our Connecticut startup page.

Mowing is outside home improvement registration, but landscaping is taxable

The Department of Consumer Protection says anyone contracting with a consumer to do home improvement work on residential property must register as a Home Improvement Contractor, and the list of covered work includes landscaping, driveways, fences and painting. The same agency lists exclusions, and property maintenance such as snowplowing, mowing, pruning, cleaning, and tree and shrub cutting is on the list. That means a mow-and-plow route business does not register as a home improvement contractor for that work. If you start building patios, retaining walls or fences for homeowners, you move into registration territory. Jobs under $200 are also excluded.

Tax is a different agency and a different answer. The Department of Revenue Services lists landscaping and horticulture services, janitorial services, window cleaning, exterminating, pool maintenance and a number of other services as subject to sales and use tax. The DRS regulation on landscaping and horticulture services lists mowing, weeding, mulching, fertilizing, raking and watering as taxable lawn and garden services, with a casual-sale exception for someone outside the trade serving three or fewer residences a season. The regulation does not address snow removal, so ask DRS about plowing. If you provide a listed service, register through myconneCT before your first invoice. The sales and use tax permit cost $100 as listed in October 2026. Read the DRS list for your service mix before you set prices, and see our guide to sales tax on services for the general method.

Pesticide work needs certified people and a registered business

Connecticut has two commercial certificate levels. A commercial supervisor decides whether and how pesticides are applied, which products are used, how they are mixed and at what dose. A junior operator applies pesticides only under a certified supervisor's direction. Ask DEEP what an operator certificate does and does not allow before you hire one. Ornamental and turf work falls under category 3A, and DEEP says anyone who uses pesticides professionally must hold a current certificate. UConn Extension runs an online course for the exam in the fall and winter. Fees and exam logistics change, so read DEEP's pages before you book.

The business itself registers too. Section 22a-66c of the General Statutes says no one may operate a pesticide application business without a certificate of registration from DEEP. Details from the statute and DEEP's registration page:

• The certificate expires on August 31 and renews annually.
• You register each place of business and each business name, and pay the fee for each.
• The fee is $240. A business that employs not more than one certified applicator is exempt from paying, but still registers.
• You tell DEEP about changes in your information within thirty days.
• Your registration number goes on the body of every vehicle used in the business, in newspaper, billboard and telephone directory advertising, and in each written contract for pesticide application.

DEEP also notes that businesses subcontracting pesticide applications must register. A landscaper with no certified supervisor who wins a contract that includes pesticide work can subcontract it to a properly registered company, but the details on DEEP's page, including who posts signs and who keeps records, matter. Read them before you promise a customer a one-stop service.

Two plant-health rules sit next to this. Connecticut bans applying neonicotinoid insecticides to linden or basswood trees (section 22a-61a), and bans applying a labeled neonicotinoid to any plant that bears blossoms unless it is grown in a greenhouse inaccessible to pollinators (section 22a-61b). Lawn programs that include ornamental beds should account for both. Municipal playgrounds are also off limits for lawn care pesticides, except for narrow emergencies, under section 22a-66m, which matters if you bid town contracts.

Customer notice, roadside signs and the neighbor registry

Section 22a-66a requires a pesticide application business, before entering an oral or written agreement, to give the customer and the property's resident or manager two things. One is notice of the neighbor registry. The other is the portion of the product label that shows the product name and registration number, the manufacturer, the active ingredients, the signal word, any emergency phone number and the precautionary statements. For any later product, you provide the label portion before its first use.

The registry works like this. Before applying within 100 yards of any property line, you give notice of the date and time to any abutting owner or tenant who asked for it. You make at least two attempts, as early as practical and not later than 24 hours before the application, by phone, mail or in person. If all attempts fail, you leave notice of the application and attempts on the door. DEEP's page says residents sign up for the next year's registry by December 31, and that a request submitted directly to a company binds that company until the registry takes effect.

Signs are separate. For an outdoor application within 100 yards of a property line, a sign goes up at the time of application at any conspicuous point of entry. A commercial applicator also posts a sign every 150 feet of road frontage of the treated property. Noncommercial applications under 100 square feet or in a fenced area are exempt, as are applications on certain agricultural land. Section 22a-66g requires the business to keep application records for not less than five years, including the commercial supervisor and operator names and certificate numbers, the kind and amount of pesticide, the date and place, and the pest treated. These records live at your place of business and are open to inspection.

All of this is a data problem. A custom CRM can store each property's label sheet, application history, abutting-neighbor requests and sign checklist so a technician does not have to remember them on a Friday afternoon.

Trees, snow and employees

Anyone advertising, soliciting or contracting for tree care in Connecticut needs an arborist license, according to DEEP, and arborist businesses register as pesticide application businesses when they do arboriculture for hire and pay the $240 fee, with no single-applicator exemption. A lawn company that adds tree care to its service list should read that page first. On workers' compensation, the Workers' Compensation Commission says with few exceptions employers must carry coverage for employees. Owners, LLC members and partners may elect to be excluded.

Season and first steps

Connecticut has four seasons. The state's startup data puts snow plowing and ice dam work from December through March, spring cleanup and mulching from April through June, and leaf removal in the fall, with mowing between them. Pair services so crews stay busy through the year.

1. Form your LLC and file the annual report each year between January 1 and March 31. Details are on our Connecticut page.
2. Register with DRS through myconneCT if you sell a taxable landscaping service.
3. Decide whether to sell pesticide programs. If yes, certify a supervisor, register the business with DEEP, and build your label, notice and sign procedure.
4. Price work with our mowing pricing guide.
5. Check each town for local rules before you start, because towns issue their own permits and may set their own business requirements.
