How to Start a Landscaping Business in Maine (2026)

Last updated: May 3, 2026

Starting a landscaping business in Maine has a lower regulatory barrier than many other states — there is no state landscaping contractor license in Maine. The primary license requirement for full-service landscaping is a commercial pesticide applicator license from the Maine Board of Pesticides Control (BPC) under the Department of Agriculture, Conservation and Forestry (DACF), required whenever your work involves applying pesticides, herbicides, or pesticide-containing fertilizers. If you offer purely manual services (mowing, planting, pruning, mulching) without any pesticide application, no state license is required — though you still must comply with local business registration requirements and Dig Safe 811 rules before any digging.

Maine’s landscaping market has distinct seasonal and geographic characteristics. The growing season in southern Maine (York, Cumberland, Knox, and Lincoln counties) runs April through October. Northern Maine (Aroostook, Penobscot, Piscataquis, and Somerset counties) has a compressed season of May through September. The coastal tourism market — from Kittery through Bar Harbor — creates strong demand for commercial and residential landscape maintenance during the summer season, with premium pricing driven by seasonal homeowners who need reliable maintenance for properties they don’t visit year-round.

How to Start a Landscaping Business in Maine (Step by Step)

Step 1: Do You Need a Pesticide Applicator License?

Maine’s licensing requirement for landscapers turns on whether your work involves pesticide application. Here’s how to think about it:

• License required: Any application of pesticides — herbicides for weed control, insecticides, fungicides, or fertilizers that contain pesticide active ingredients (many “weed and feed” products). Even a one-time application of weed killer makes you a commercial applicator requiring BPC certification.
• License NOT required: Purely manual work — mowing, planting, pruning, mulching, raking, irrigation installation (no pesticide application), and hardscaping such as patio and walkway installation. However, most full-service landscaping businesses want to offer a complete menu of services including weed control, which means getting licensed.
• Arborists: Note that Maine DACF also issues an Arborist License for any tree pruning or removal services offered for hire. If you offer tree work, verify current arborist licensing requirements with Maine DACF separately from the BPC pesticide license.

Step 2: Maine Board of Pesticides Control License Structure

The Maine Board of Pesticides Control (BPC) at maine.gov/dacf/php/pesticides licenses commercial pesticide applicators at two levels:

Commercial Operator

A Commercial Operator works under a licensed Commercial Master. Cannot independently operate a firm or sign permits, but can apply pesticides under Master supervision. License fee: $105 (3-year term, renewable December 31). Requires: Core exam + at least one Category exam. CE: 6 hours per 3-year term. A company must have at least one licensed Commercial Master before Commercial Operators may be licensed under it.

Commercial Master

A Commercial Master can independently operate a pesticide application firm, supervise Operators, and take full regulatory responsibility. License fee: $105 (3-year term, renewable December 31). Requires: Core exam + at least one Category exam + Regulations exam + oral exam with BPC staff. CE: 9 hours per 3-year term. Firm license: $300 (separate from individual license). If you are starting a landscaping company that applies pesticides, you need both a Commercial Master individual license and a firm license.

Step 3: The Exam Process

All commercial applicant exams are administered by BPC staff:

• Location: BPC offices, Augusta (usually Wednesday mornings) — the most frequent option. Monthly exams in Presque Isle for northern Maine applicants. Contact BPC to schedule: (207) 287-2731 or maine.gov/bpc (online portal).
• Core exam ($10): Required for all commercial applicants. Covers general pesticide information, toxicity, environmental hazards, label reading, personal protective equipment, and applicable regulations.
• Category 3A exam ($10): Outdoor Ornamentals/landscape pest management — specific to ornamental trees, shrubs, flowers, and landscape plantings.
• Category 3B exam ($10): Turf pest management — specific to lawn care, turf grass pest identification and management.
• Regulations exam ($10) + Master’s oral exam ($40): Required only for Commercial Master applicants. The oral exam is conducted by BPC staff and evaluates practical knowledge of pesticide regulations and compliance.

Government employees have exam fees waived. Study materials: the University of Maine Cooperative Extension offers pesticide applicator manuals and training resources at extension.umaine.edu/ipm/pesticide-safety/manuals. Each category has its own study manual.

Step 4: License Maintenance — Certification and License Terms

Maine’s BPC operates with distinct certification and license timelines that applicants frequently confuse:

• Commercial license: 3-year term, renewable December 31. Fee: $105 per renewal cycle.
• Commercial certification: Valid for 6 years. Passing the exams establishes your certification; meeting CE requirements renews your certification.
• CE requirements: Commercial Masters: 9 hours per 3-year license term; Commercial Operators: 6 hours. CE must be from BPC-approved sources.
• Firm license renewal: $300 per year (separate from individual license).
• All license renewals are due December 31 of the renewal year.

Step 5: Dig Safe 811 — 3-Business-Day Requirement

Any Maine landscaping work involving mechanical excavation — digging beds, installing irrigation, grading, fence post installation, or any powered equipment that disturbs the ground — requires a Dig Safe notification at least 3 full business days in advance. Maine statute: Title 23, § 3360-A and MPUC Rules Chapter 895.

• Call 811 (toll-free) or submit at digsafe.com
• Utilities will mark underground lines with color-coded flags or paint within the notification window
• Wait for all utilities to respond before beginning excavation
• The Maine Public Utilities Commission (MPUC) enforces compliance with fines up to $10,000 per violation
• Hand digging (non-mechanical) is not subject to the notification requirement, but calling 811 is always strongly encouraged
• Notification is valid for a specific area for 10 working days after marking is complete

Maine’s Dig Safe System (digsafe.com) covers Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont — one call covers all member utilities in the notification area. Non-member utility owners (private underground installations) must be separately notified by the excavator.

Step 6: Maine Sales Tax on Landscaping Services

Maine’s tax treatment of landscaping services is generally favorable:

• Landscaping labor services are generally NOT taxable in Maine. Mowing, pruning, planting, maintenance visits, and other landscaping services are not subject to Maine’s 5.5% sales tax. Maine does not tax most services unless specifically enumerated.
• Materials sold to customers ARE taxable. Plants, trees, mulch, soil, fertilizers, and other materials you supply and charge to customers are taxable at 5.5% unless you pay sales tax at the point of purchase from your supplier (in which case you’ve already paid the tax and don’t charge it again to the customer).
• Lump-sum contracts: If you charge one price for a project that bundles labor and materials (e.g., “plant 10 shrubs for $500”), you may owe tax on the material portion. Consult Maine Revenue Services at (207) 624-9693 or revenue.maine.gov for guidance on how your specific contract structures are treated.

Step 7: Business Formation and Payroll

Form an LLC ($175 by mail to the Maine Secretary of State, 10-15 business days). Annual Report: $85 due June 1. For employees:

• Workers’ compensation: Required at the first employee. NCCI codes 0042 (landscaping) and 0008 (tree trimming) are typical for Maine landscaping businesses.
• Maine Paid Leave (PFML): Register at maine.gov/paidleave before first payroll. Benefits start May 1, 2026. Rate: 1.0% for 15+ covered individuals (split 50/50); 0.5% employee-only for under 15.
• Maine Earned Paid Leave (EPL): At 11+ employees, workers accrue 1 hour of paid leave per 40 hours worked (26 M.R.S. § 637).
• Minimum wage: $15.10/hr statewide; Portland: $16.75/hr; Rockland: $16.00/hr.
• New hire reporting: Within 7 days at portal.maine.gov/newhire.

Maine Landscaping Market: Where the Demand Is

Maine’s landscaping market divides cleanly into three segments. Southern coastal Maine (York and Cumberland counties) — from Kittery to Portland — has the state’s highest-income residential market, with significant demand for design/build landscaping (hardscaping, patio installation, water features) and premium maintenance contracts from seasonal and year-round homeowners. Portland proper has a growing commercial landscaping market driven by HOAs, mixed-use developments, and the commercial real estate build-out in the waterfront and Bayside districts.

The mid-coast and Downeast region (Knox, Waldo, Hancock, and Washington counties) serves a large seasonal homeowner market. Maine has over 200,000 seasonal properties, predominantly along the coast and in the lakes regions. These seasonal homeowners typically want reliable maintenance contracts with documented service records — grounds maintained while they’re away. This creates a recurring revenue opportunity that often continues even when owners sell and new buyers want continuity. Aroostook County is the outlier: primarily agricultural land with significant potato farming and commercial acreage, but very limited residential landscaping demand outside the Presque Isle and Caribou commercial areas. Snow plowing contracts are an important revenue source for northern Maine landscaping businesses that need winter income during the 6-7 month off-season.
