Regulations & Compliance Requirements
Effective Date: May 20, 2026
Overview
One Stop Tree Shop Inc., a Delaware corporation ("OSTS"), is committed to promoting safe, professional, and legally compliant tree care services. This Regulations Section establishes the compliance framework that all Service Providers must meet to use the OSTS Platform. It also informs Customers of the standards OSTS upholds and the regulatory landscape governing tree care work.
Failure to comply with these requirements may result in suspension or termination of a Service Provider's account and may expose a Service Provider to civil and criminal liability.
Part I: Service Provider Licensing Requirements
1.1 Why Licensing Matters
Tree care work — including tree removal, climbing, rigging, and chemical application — is regulated at the state, county, and municipal level across the United States. Unlicensed or uninsured tree care work exposes homeowners to property damage liability and may void homeowner's insurance claims. OSTS takes licensing seriously and verifies credentials before and during Platform participation.
1.2 Federal-Level Requirements
There is no single federal license required to perform tree care work. However, federal requirements apply in specific circumstances:
| Requirement | Applicability |
|---|---|
| DOT Commercial Driver's License (CDL) | Required if operating commercial vehicles over 26,001 lbs GVWR |
| EPA Pesticide Applicator License | Required when applying restricted-use pesticides; administered by states under federal delegation |
| OSHA Compliance (29 CFR 1910 / 1926) | OSHA standards apply to all tree care operations with employees; key standards include 1910.266 (logging) and are often guided by ANSI Z133 |
| IRS Employer Identification Number (EIN) | Required for businesses with employees or operating as a partnership/corporation |
1.3 State Licensing Requirements
Licensing requirements vary significantly by state. OSTS requires all Service Providers to hold all licenses required in every jurisdiction where they perform work. The following is a non-exhaustive overview of key state requirements:
| State | Requirement | Administering Body |
|---|---|---|
| California | C-27 or D-49 contractor license for jobs over $500; Qualified Applicator License for pesticide use | CA Contractors State License Board; CA Dept. of Pesticide Regulation |
| Colorado | Certified Arborist license for commercial tree work | CO Dept. of Agriculture |
| Connecticut | Commercial Arborist License required for any arboriculture work for compensation | CT Dept. of Energy & Environmental Protection |
| Florida | Arborist license required; varies by county | FL Dept. of Agriculture; local jurisdictions |
| Maryland | Arborist license required to perform tree work for compensation | MD Dept. of Natural Resources |
| Massachusetts | Arborist license required; municipal tree work may require additional permits | MA Dept. of Conservation & Recreation |
| New Jersey | Tree Expert License required; Tree Surgeon License for certain operations | NJ Dept. of Environmental Protection |
| New York | No statewide license, but NYC requires specific certification | Local jurisdictions; NYC Dept. of Parks |
This table is a general reference only and may not reflect the most current requirements. Service Providers are solely responsible for researching and complying with all applicable licensing requirements.
1.4 Municipal and County Permits
Many jurisdictions require permits for specific tree work, independent of professional licensing:
- Tree removal permits: Required in many cities and counties for removing trees above a certain size (typically 6-12 inches DBH), for heritage/protected trees, or in regulated zones
- Right-of-way permits: Required when work encroaches on public streets or sidewalks
- Utility notification: Federal and state law (811 "Call Before You Dig") requires notification of underground utility locates before any digging, including stump grinding
- Utility clearance: Work within proximity of overhead power lines requires coordination with the utility company and may require line clearance arborist credentials
Service Providers are responsible for obtaining all required permits before commencing work.
Part II: Insurance Requirements
2.1 Mandatory Insurance for All Service Providers
All Service Providers must maintain the following insurance coverage at all times while active on the Platform:
General Liability Insurance
- Minimum coverage: $1,000,000 per occurrence / $2,000,000 aggregate
- What it covers: Property damage, bodily injury to third parties, and personal injury arising from tree care operations
- Required endorsement: OSTS must be listed as an Additional Insured on the policy
Workers' Compensation Insurance
- Required in all states where mandated by law for employers
- Sole proprietors with no employees should confirm their state's requirements
- Minimum coverage as required by state law

Part IV: Safety and Environmental Regulations
4.1 OSHA Standards
Service Providers with employees must comply with applicable OSHA standards, including:
- 29 CFR 1910.268 / 1910.269: Electrical safety for work near energized lines
- 29 CFR 1910.134: Respiratory protection (where applicable)
- 29 CFR 1926.21: Safety training for construction work
- ANSI Z133: The tree care industry's primary safety standard, referenced by OSHA
- ANSI A300: Industry best practice standards for pruning, cabling, soil management, and other arboricultural practices
4.2 Environmental Regulations
Service Providers must comply with applicable environmental laws, including:
Protected Trees and Species: Many states, cities, and counties protect certain tree species, heritage trees, or trees in designated zones. Removing a protected tree without a permit can result in significant civil fines and criminal penalties.
Invasive Species: Moving untreated wood across state or county lines may be restricted to prevent spread of invasive pests (e.g., Emerald Ash Borer, Spotted Lanternfly). Service Providers must comply with applicable quarantine orders.
Pesticide Application: Application of herbicides, insecticides, or fungicides near waterways, wetlands, or in sensitive ecological areas is regulated by the EPA and state environmental agencies. Service Providers must hold appropriate Pesticide Applicator Licenses.
Stump Grinding and Soil Disturbance: In some jurisdictions, stump grinding or grading may require grading permits. 811 underground utility notification is required before stump grinding.
4.3 Noise and Hours of Operation
Many municipalities restrict the use of power equipment (chainsaws, chippers, stump grinders) to specific hours (commonly 7 AM - 9 PM on weekdays; 8 AM - 8 PM on weekends). Service Providers must comply with local noise ordinances.
Part V: Customer Responsibilities
5.1 Property Ownership and Authorization
Customers represent that they are the property owner, authorized agent of the property owner, or have obtained all necessary permissions before booking tree care services. Requesting work on trees that you do not own or have authority over may constitute trespass and may expose you to civil liability.
5.2 Disclosure of Hazardous Conditions
Customers must disclose to the Service Provider any known hazardous conditions on the property prior to service, including:
- Proximity of trees to overhead utility lines, underground utilities, structures, or water features
- Known soil conditions (instability, underground voids, septic systems)
- Presence of bees, wasps, or other hazardous wildlife in or around the tree
- Known tree health issues (decay, disease, root damage)
- Any prior tree work or modifications to the tree structure
Failure to disclose material conditions may affect your ability to seek damages in the event of an incident.
5.3 Utility Locate Requirement
For services involving ground disturbance (stump grinding, root pruning, soil work), Customers should ensure the 811 utility notification has been completed or confirm with the Service Provider that they have initiated the locate request. The 811 hotline is a free service available in all 50 states.
Part VI: Dispute Resolution and Regulatory Complaints
6.1 Disputes Between Customers and Service Providers
Disputes should first be raised through OSTS's Platform dispute resolution process. See the Terms of Service, Section 5.4 and Section 13 for dispute procedures.
6.2 Regulatory Complaints
If a Customer believes a Service Provider has performed unlicensed work, caused property damage, or violated applicable laws, they may file complaints with:
- State Contractor Licensing Board (for unlicensed contracting)
- State Attorney General / Consumer Protection Division (for fraud, deceptive practices)
- State Insurance Department (for insurance-related issues)
- OSHA (for safety violations endangering workers or the public)
- EPA or State Environmental Agency (for pesticide misuse, environmental damage)
- ISA (for misuse of ISA certifications)
- TCIA (for complaints against TCIA-accredited companies)
6.3 Reporting to OSTS
Service Providers who become aware of regulatory violations by other Service Providers on the Platform are encouraged to report concerns to OSTS at Info@onestoptreeshop.com. OSTS will investigate and take appropriate action, up to and including account termination and referral to regulators.
Part VII: Updates to Regulations
7.1 Changing Requirements
Tree care regulations evolve. State legislatures, local governments, and regulatory agencies regularly update licensing, insurance, and environmental requirements. OSTS will make reasonable efforts to keep this Regulations Section current, but Service Providers are solely responsible for staying informed of and complying with all applicable laws and regulations in their jurisdictions.
7.2 Notification of Changes
OSTS will notify registered Service Providers of material changes to OSTS's Platform compliance requirements via email and Platform notification. Regulatory changes imposed by governmental bodies take effect regardless of OSTS notification.
