Starting a landscaping business in Connecticut can be a fantastic opportunity for entrepreneurs who love working outdoors and transforming spaces. It comes with lots of paperwork.
Whether you’re planting gardens, installing patios, or applying lawn treatments, Connecticut has clear rules to help protect both you and your customers. For that, you need to understand the licensing, certification, and registration requirements in the state.
This article will guide you through the essentials so that you can get your landscaping business up and running legally and smoothly.
Licensing Requirements for Landscaping Businesses in Connecticut
Landscaping in Connecticut is acknowledged as a skilled profession and some activities might need special permits or registrations.
What you should know is as follows:
You might need a Home Improvement Contractor (HIC) Registration with the Connecticut Department of Consumer Protection (DCP) if you plan to provide services like lawn installation, tree, shrub, or flower planting, as well as other significant landscaping work.
While Connecticut has no separate “landscaping contractor license,” many landscaping services fall under home improvement work.
There are no specific tiers or square footage categories as seen in some states, but you must register if your business offers services like:
- Lawn installations
- Tree and shrub planting
- Hardscape installation (like patios or retaining walls)
You can register as a HIC on the CT DCP eLicense website:

2. Pesticide Applicator License (for pest control)
You might need a Pesticide Applicator License if you plan to apply pesticides as part of your lawn care services (such as weed control, insect treatments, or fungicides). The pesticide applicator License is issued by the Connecticut Department of Energy and Environmental Protection (DEEP).
There are two types:
- Supervisory Pesticide Applicator Certificate – (for those in charge of pesticide application).
- Operational Pesticide Applicator Certificate – (for workers applying pesticides under supervision).
To qualify, you need to:
- Pass the main exam and a category exam based on the type of pesticide work you’ll perform.
- Attend pesticide safety meetings and stay updated on best practices.

3. Nursery Dealer License
If you plan to sell nursery stock (such as trees, shrubs, or other plants), register as a Nursery Dealer with the Connecticut Agricultural Experiment Station (CAES).

4. Surety Bond and Insurance Requirements
Connecticut requires home improvement workers, including landscapers, to carry proper insurance and, in some cases, a surety bond:
The Surety Bond: While not mandatory for all, a surety bond (often around $15,000) can protect your clients and it is recommended if you handle larger projects.
Insurance Requirements-
General Liability Insurance:
- $100,000 minimum for bodily injury per occurrence
- $50,000 minimum for property damage per occurrence
- $5,000 minimum for medical payment coverage
Carrying insurance not only protects your business but also builds customer trust.
5. Business Registration
Before any legal operations in Connecticut, you need to register your business entity with the Connecticut Secretary of the State (SOTS). This applies whether you’re a sole proprietor, LLC, partnership, or corporation.

You can register online at: https://portal.ct.gov/SOTS.
