2. Connecticut Commercial Pesticide Applicator Certification (CT DEEP)

   Applying pesticides or herbicides commercially as part of landscaping services in Connecticut requires certification from the Department of Energy and Environmental Protection - not the Department of Agriculture. Applicators certify by category after passing DEEP's exam; a commercial supervisory certification is what lets a business direct pesticide use, while operators work under a supervisor. Certification is renewed every five years.

1. New Haven zoning compliance and category-specific licenses (no general business license)

   New Haven issues no blanket general business license renewed annually and displayed at the place of business, and Connecticut has no statewide one. The city's Licenses & Permits index routes 'Business License' to the Permit & License Center, whose licences are strictly category-specific - Amusement, Auction and Auctioneer, Broker, Rooming House, Sales and Street Vendor/Peddler - with applications presented in person. What does apply to a business generally is zoning: the premises need a zoning permit or zoning compliance confirmation and a Certificate of Occupancy from the Office of Building Inspection & Enforcement under CGS Sec. 29-265. Note also that the department issuing building and licence approvals is the Office of Building Inspection & Enforcement, not Economic Development.

2. Connecticut Home Improvement Contractor Registration (residential landscaping work)

   There is no New Haven County registration - Connecticut abolished county government in 1960 - and New Haven runs no separate municipal landscaping contractor registry. Landscapers who make permanent changes to residential property, such as installing irrigation or hardscaping, must register as a Home Improvement Contractor with the Department of Consumer Protection; routine mowing and maintenance is not covered and commercial property is outside the registration. Registration requires general liability insurance of at least $20,000, and irrigation work tied into plumbing requires a state trade license.

   Official government source
