How to start a tree service business

This guide takes a climber or crew leader from licensing to an insured tree company with its first jobs, quoting the rules in California, Maryland, New Jersey, Florida and Texas. The most useful finding: OSHA still has no tree care standard, so inspectors cite general industry rules and the General Duty Clause and look to ANSI Z133-2026, and anyone not trained in line clearance must keep ten feet from power lines.

Licensing: Statewide in California (C-49), Maryland (Licensed Tree Expert) and New Jersey (business registration); none found in Texas or Florida
Maryland: No advertising or performing tree work for hire without a license; $30 license, 140-question exam
New Jersey: $1,000,000 in general liability and one full-time licensed person in every registered company
Safety rules: No OSHA tree care standard yet; general industry rules, the General Duty Clause and ANSI Z133-2026
Credential: ISA Certified Arborist: three years of full-time experience; accepted as a New Jersey LTCO
Workforce: 60,100 tree trimmers and pruners in 2024; median $24.50 an hour in 2025 (BLS via O*NET)

What a tree company does, and which kind to open

California’s license class gives the plainest job description: “A Tree and Palm contractor plants, maintains, and removes trees and palms. The duties include pruning, stump grinding, and tree, palm, or limb guying” (California CSLB, C-49). Maryland’s law reaches anyone working on trees for pay “whether under the title of arborist, tree specialist, tree surgeon, tree expert, or otherwise” (Maryland DNR, tree laws), so the name on the truck does not change which rules apply.

Most new companies are started by an experienced climber and take one of these shapes:

Residential removal, pruning and stump grinding. The core of most young companies, and the work California, Maryland and New Jersey license.
Storm response. Removals after wind, ice and hurricanes. The Atlantic hurricane season runs from June 1 to November 30 (National Hurricane Center), and storm weeks are when states warn homeowners about unlicensed crews.
Utility line clearance. Contract work for utilities under OSHA’s line-clearance rules, with its own registered apprenticeship title, “Tree Trimmer (Line Clear),” and its own tax treatment in Texas.
Plant health care and consulting. Treatments, which bring in pesticide licensing, and risk assessments, which carry legal weight in Florida when an ISA Certified Arborist signs them.

Pay, demand and who you are up against

Bureau of Labor Statistics figures on O*NET OnLine put the median tree trimmer and pruner at $24.50 an hour, or $50,960 a year, in 2025, well above general landscaping work. It is a small occupation: 60,100 people in 2024, average growth of 3% to 4% projected to 2034 and 7,400 projected openings. Every O*NET respondent wears protective equipment daily, and 71% face hazardous equipment daily. Registered apprenticeship titles include “Arborist” and “Tree Surgeon.”

There is no Census code of its own. Tree work sits inside NAICS 561730, Landscaping Services, whose index lists “Tree pruning services” and “Tree and brush trimming, overhead utility line,” and whose largest firms include Asplundh, Lewis Tree Service and Davey Tree (NAICS 561730). Any landscaping count mixes tree companies with mowing routes.

Licensing: three states license tree work, most leave it to cities

No federal license exists for tree care. A few states license it statewide, others leave it to cities and counties, and pesticide, power line and roadside rules apply nearly everywhere. The SBA says the licenses you need “will depend on your business activities and business location,” and TCIA tells homeowners to check whether their city licenses arborists, noting that “many communities do” (TCIA, hiring a tree care company).

State	Agency	What you need	Key requirements, as the agency states them
California	Contractors State License Board	C-49 Tree and Palm contractor license	Needed for work that requires a permit, uses other workers or reaches $1,000; trade exam for all applicants since January 1, 2024; four years of journey-level experience; $25,000 bond
Maryland	Department of Natural Resources, Forest Service	Licensed Tree Expert	Required to perform or advertise tree work for hire; age 18; three years with a licensed tree expert, or two years of college plus one year; 140-question exam; liability and property damage insurance
New Jersey	Board of Tree Experts	Business registration every two years, plus a licensed operator or expert on staff	One licensed person working full time; $1,000,000 general liability or letter of credit; workers’ comp for employees; written safety policy within 90 days
Florida	Tree statute (Fla. Stat. 163.045)	No statewide tree license found	Local governments may not require a permit for a residential tree an ISA Certified Arborist documents as an unacceptable risk
Texas	Power line statute (Health and Safety Code 752.004)	No statewide tree license found; city permits apply	No tool or equipment within six feet of a high voltage overhead line without arrangements with the operator

Fees are as of October 2026. Rules change, so confirm each with the issuing agency and with your city or county before you advertise or climb.

California

CSLB created the C-49 “to ensure tree service contractors are tested on health and safety protocols in the tree service industry,” and from January 1, 2024 “All applicants for the C-49 Tree and Palm Contractor classification will need to sit for a trade examination regardless of other license classifications they hold.” Holders of the older C-61/D-49 “may retain and work under that classification,” and “CSLB regards the classification of work as the same” (CSLB bulletin 23-07). The exam leans on safety, its largest section at 30%, ahead of “Pruning and Maintenance (25%)” and “Planning and Estimating (22%)” (C-49 study guide).

The contractor law names “Any person not otherwise exempt by this chapter, who performs tree removal, tree pruning, stump removal, or engages in tree or limb cabling or guying,” and excludes only a gardener doing incidental pruning of trees “less than 15 feet in height after planting” (Cal. Bus. & Prof. Code 7026.1). The general threshold applies: a license is needed when the work needs a permit, uses workers or totals “$1,000 or more” (CSLB, before applying). Applicants need four years at journey level, with up to three creditable from training (CSLB, experience), a $450 application and a $200 or $350 initial license (CSLB fees), and a $25,000 bond or cashier’s check (CSLB, issuing your license).

Workers’ comp is not optional for tree work there. CSLB requires “C-61/D-49 Tree Service contractors … to carry workers’ compensation insurance or a valid Certification of Self-Insurance, whether or not they have employees” (CSLB, workers’ compensation). That page does not yet name the C-49, but since CSLB treats the work as the same, plan to carry it and confirm with CSLB.

Maryland

“A person may not engage in the work or business of a tree expert without a license issued by the Department.” Employees working under a Licensed Tree Expert’s supervision do not need their own. Candidates must be 18 and have either “2 years of approved college education in forestry, arboriculture, horticulture, applied agricultural sciences, or the equivalent” plus a year with a licensed tree expert, or three continuous years working with a licensed tree expert in Maryland or “an acceptable tree expert company in another state.” The exam has “140 questions, 14 in each domain,” and “A passing score of 70% is required for each individual domain, as well as for the overall test”; it is offered “ten times per year” (Maryland DNR, new tree expert).

The fees are small: “The fee to obtain this license is $30.00,” retakes cost $20 per domain, and renewal is $20 (Maryland DNR application). Insurance is the larger commitment: every licensee “must carry and show proof of liability and property damage insurance, in the form and amount required by the Department,” with DNR listed as a certificate holder. The pages we opened did not state the dollar minimums, so ask DNR before you buy a policy.

The advertising rule is what catches newcomers. “Maryland law requires anyone advertising or performing tree care for hire - including removal - to hold a Tree Expert License,” and licensees must “display their license number on trucks, proposals, contracts, and advertisements” (Maryland LTE brochure). The license is not needed for “Work on trees under 20 feet tall.” Separately, “Before a roadside tree is trimmed or cared for in any way, including the application of pesticides, a Tree Care Permit must be obtained from the Maryland DNR Forest Service,” and a roadside tree is any woody plant growing “all, or in part, within a public road right-of-way” (Maryland DNR, tree laws).

New Jersey

New Jersey licenses the company and the people. “Every Business engaged in providing tree care services for hire in New Jersey shall register biennially with the Board,” out-of-state companies included, and working unregistered can bring civil penalties “of up to $1000.00 for the first violation.” A registered business must “Have at least one licensed individual working full time in the company,” carry “$1,000,000 of general liability insurance or a letter of credit in the amount of $1,000,000,” cover employees with workers’ comp and, “Within 90 days of registering the Business … develop and establish a written comprehensive safety policy” (NJ Board of Tree Experts, businesses). The registration number goes “on every service vehicle,” in letters “three inches high and located on at least two sides,” and in every ad as “NJTC Registration” followed by the number (NJ Board, advertising).

There are two personal licenses. “The Licensed Tree Care Operator (LTCO) is for companies that only provide standard tree care work like pruning, removals and stump grinding,” and the Licensed Tree Expert covers more specialized work. LTCO candidates need to be 18, with three references, a high school diploma or equivalent and “at least three years” in arboriculture; the application fee is $50 (NJ Board, exam qualifications). The shortcut: “the ISA Certified Arborist (CA) credential is equivalent to the Licensed Tree Care Operator (LTCO) certification” (NJ Board, licensing).

Florida

We found no statewide tree license on a Florida page, so ask your county and city. What Florida does have is a statute that rewards a credential: “A local government may not require a notice, application, approval, permit, fee, or mitigation for the pruning, trimming, or removal of a tree on a residential property if the property owner possesses documentation from an arborist certified by the ISA or a Florida licensed landscape architect that the tree poses an unacceptable risk to persons or property,” based on an onsite assessment under ISA’s tree risk assessment best management practices, and “A local government may not require a property owner to replant” (Fla. Stat. 163.045). A company with a certified arborist can sell that assessment as its own service.

Texas

No statewide tree license turned up in Texas; cities regulate instead. Austin, for example, “regulates three classifications of trees: 8- to 18-inch diameter, Protected Trees, and Heritage Trees” (City of Austin). The state’s sharpest rule is about power lines: no one may “bring any part of a tool, equipment, machine, or material within six feet of a high voltage overhead line.” Closer work requires notifying the operator “at least 48 hours before the work begins” and a “mutual arrangement” for de-energizing or barriers, with the responsible person paying “the actual expense” (HSC 752.003). If contact happens anyway, the violator “is liable to the owner or operator of the line for all damages” (HSC 752.008). Plant health care needs a TDA license, which covers anyone applying “any pesticide … to ornamental plants, trees, lawns, or weeds for hire” (TDA).

Credentials that open doors

ISA Certified Arborist. ISA requires “a minimum of three years of full-time experience in arboriculture or a combination of education and practical arboricultural experience,” with a full-time year equal to “approximately 1,795 hours of work”; a two-year degree in the field cuts it to two years, a four-year degree to one. As of October 2026 the application fee is $40 for members and $50 for others, and the exam enrollment fee is $295 for members and $369 for others (ISA program guide), with continuing education to keep it (ISA, Certified Arborist). It is the credential New Jersey accepts as an LTCO and the one Florida’s statute names.

TCIA Accreditation is “a third-party consumer confidence verification program” that lasts three years with “renewal check-ups required every year” (TCIA Accreditation). TCIA’s Certified Treecare Safety Professional credential is a nearer goal for a crew leader.

Setting up the company

Entity and EIN. The SBA says an LLC protects personal assets “in most instances,” and the IRS charges nothing for an EIN.

Insurance. Google’s Local Services Ads require general and professional liability for the tree service category. New Jersey sets a $1,000,000 general liability floor, Maryland sets its own liability and property damage terms, and TCIA tells homeowners to “ask to see current certificates of liability and workers’ compensation insurance” before work starts. In our experience commercial auto for chip trucks and coverage for the chipper and grinder belong on the policy from day one, and tree work’s injury record makes the premium one of the largest early costs.

Workers’ comp:

California: required for tree service contractors whether or not they have employees (CSLB).
New Jersey: required for employees of every registered business (NJ Board).
Florida: four or more employees outside construction (Fla. Stat. 440.02); we could not confirm whether tree work counts as construction there.
Texas: optional for most private employers, according to the Texas Department of Insurance.

Climbers and classification. The IRS weighs “Behavioral,” “Financial” and “Type of relationship” factors, and treating an employee as a contractor with “no reasonable basis for doing so” can leave the company owing the employment taxes (IRS, contractor or employee). Calling a climber a subcontractor does not, in our experience, move an injury or a damaged roof off your company.

Sales tax in Texas. “Trimming, spraying, and maintaining trees” and removing plants are taxable landscaping services, but “Trimming trees away from power lines” is not (Texas Comptroller 94-112).

Trucks, chippers and rigging

From what we see in young tree companies, the equipment comes in stages:

Day one. Saws with cut-resistant leg protection for every operator, climbing gear and rigging, a chipper, a chip truck or dump trailer and a stump grinder.
Licenses for the truck. A combination over 26,001 pounds with a towed unit rated over 10,000 pounds, or a single vehicle at 26,001 pounds or more, needs a commercial driver’s license (49 CFR 383.5), and interstate vehicles at 10,001 pounds or more fall under federal safety rules (49 CFR 390.5). A chip truck towing a chipper can cross both lines, so check the ratings before you buy.
The yard. Room for trucks and wood, and somewhere to dump chips.

Pricing, storms and cash

No source with a stated method publishes a tree service startup cost, so none is given here; trucks, the chipper, the grinder and insurance are usually the largest lines. Jobs are bid after a site visit. Thumbtack’s platform data shows homeowners a national average of $450 to $1,450 to remove one tree (Thumbtack), an average from its own listings rather than a cost.

Storm work brings an insurance conversation. The Insurance Information Institute says that when a tree hits an insured structure, a homeowners policy covers removal “generally up to about $500 to $1,000,” and that “poor maintenance is not covered by homeowners insurance” (Triple-I).

Payment terms are a trust signal here. The FTC warns storm victims that “Scammers ask you to pay for everything up front” and that they “claim they don’t need to be licensed to do the work.” A written estimate, a work order and payment on completion, with deposits kept for crane jobs, set a new company apart from the crews the FTC is describing.

Safety: no OSHA tree standard, but plenty of rules

There is no tree care standard yet. OSHA’s 2021 inspection guidance says “Many of the hazards found in tree care and tree removal operations are addressed by OSHA’s General Industry standards (29 CFR § 1910),” and that citations may also come under the General Duty Clause. It names “Fall and struck-by hazards” as “leading causes of death and serious injury for tree care workers,” requires climbing anchorages “[c]apable of supporting at least 5,000 pounds (22.2 kN) for each employee attached,” checks for “cut-resistant leg protection while operating chain saws,” and looks to ANSI Z133 and “ANSI B175.1-2012” for chainsaws (OSHA inspection guidance). In June 2026 TCIA reported that OSHA’s construction advisory committee “unanimously recommended that OSHA move forward with developing a dedicated Tree Care standard,” that OSHA “frequently relies on” ANSI Z133, now “ANSI Z133-2026,” and that “a final OSHA rule has not yet been issued” (TCIA). Buy the current Z133 and train to it. A 1998 OSHA letter called the logging standard’s definition “broad enough to include commercial tree cutting and trimming” (OSHA, 1998 interpretation), so read that too.

Power lines. OSHA’s QuickCard says “All tree trimming or removal work within ten feet of a power line must be done by trained and experienced line-clearance tree trimmers,” with “A second tree trimmer” within voice range (OSHA QuickCard). Unqualified workers aloft near lines of 50 kV or less keep at least “10 ft. (305 cm)” away (29 CFR 1910.333), and utility clearance work falls under 29 CFR 1910.269. Turn down work inside that distance until someone on the crew is trained for it.

The chipper. OSHA’s tree care page lists fatality reports that include “A 23-Year-Old Worker Pulled into a Wood Chipper on His First Day on the Job” (OSHA, tree care hazards). Nobody feeds a chipper before being trained on it, and training happens “in a language and vocabulary workers can understand” (OSHA). New Jersey’s written safety policy is a sound model even where it is not required.

Finding the first customers

Google Business Profile. A tree company serves customers at their homes, so Google says to “remove your address from your Business Profile” in that case and allows “up to 20 service areas” (Google, service areas). A virtual office “isn’t eligible” (Google guidelines), and Google chooses how you verify (Google, verification).

Local Services Ads. “Tree service professionals plant, remove, and maintain trees, among other services,” in Google’s words. Screening covers general and professional liability insurance, business and owner checks for select advertisers and state licenses “where applicable by local law,” so Maryland and New Jersey companies should expect their licenses to be checked; it averages 3 to 4 weeks (Google Local Services requirements). Tree service was not in the August 2026 first phase of the move into Google Ads, and the remaining categories follow in late 2026 or 2027 (Google Ads, migration).

Reviews. Fewer than 20 reviews loses a tree company nearly half its searchers: 47% of consumers in BrightLocal’s 2026 survey said they would not use such a business. Ask after every job, pruning included, and never tie a reward to the rating, which the FTC’s 2024 rule bans.

Partners. In our experience the early referrals come from landscapers who cannot take large trees (in California, anything over 15 feet), roofers and restoration companies after storms, property managers, HOAs and real estate agents. TCIA tells homeowners not to “just hire someone with a chainsaw who knocks on your door!”, so show your license and insurance everywhere.

Our page on marketing for tree service companies covers storm weeks, the dormant pruning season and the first ninety days. Get your Google Business Profile verified first, then add Google Ads and Local Services Ads.

What trips up new tree companies

Working near lines untrained. OSHA’s tree care fatality reports include electrocutions, and in Texas contact makes you liable for all damages.
Advertising before the license in Maryland. The law covers advertising, not only the work.
Underinsuring in New Jersey. Registration needs $1,000,000 in general liability and a licensed person on staff full time.
Skipping workers’ comp in California. Tree contractors must carry it with or without employees.
Assuming no standard means no rules. OSHA cites general industry rules and the General Duty Clause, measured against Z133.
Trimming a Maryland roadside tree. It needs a state permit first.

Questions people ask before starting a tree service

Do you need a license to start a tree service?

In California, Maryland and New Jersey, yes. California requires a C-49 for jobs of $1,000 or more, Maryland requires a Licensed Tree Expert license to perform or advertise tree work, and New Jersey requires business registration with a licensed person on staff; no statewide license was found in Texas or Florida, but cities may require one.

Is ISA certification required to run a tree company?

No state reviewed here requires it on its own. It counts as a Licensed Tree Care Operator license in New Jersey, gives a certified arborist’s risk assessment legal force in Florida, and takes three years of full-time experience or a degree plus experience.

Does OSHA have a tree care standard?

Not yet. OSHA cites its general industry standards and the General Duty Clause and looks to ANSI Z133, now the 2026 edition, and its advisory committee recommended a dedicated tree care standard in 2026.

How close can a tree crew work to power lines?

Within ten feet, only trained line-clearance tree trimmers may work, with a second trimmer in voice range. In Texas, work within six feet of a high voltage line also requires 48 hours’ notice to the operator and an arrangement you pay for.

What insurance does a tree service need?

General and professional liability for Google’s Local Services Ads, at least $1,000,000 in general liability in New Jersey, the liability and property damage coverage Maryland’s DNR sets, and workers’ comp in California even with no employees.

Do I need a CDL for a chip truck and chipper?

Only if the combination is rated at 26,001 pounds or more with a towed unit over 10,000 pounds, or the truck alone is rated at 26,001 pounds or more. Check each vehicle’s ratings before you buy.

Will homeowners insurance pay for the removal?

Usually only part of it. Triple-I says policies generally cover removal up to about $500 to $1,000 when a tree hits an insured structure, and nothing for damage caused by poor maintenance.
