How to Start a Landscaping Business in Hawaii (2026)

Last updated: May 1, 2026

Landscaping in Hawaii is structurally different from landscaping in any other U.S. state because of one fact: the Plant Quarantine Branch at what is now the Hawaii Department of Agriculture and Biosecurity (DAB) regulates the import of every single plant, soil, seed, and many growing media into Hawaii. Under HRS Chapter 150A, all agricultural material arriving in Hawaii must be inspected; many plants and all soil are completely prohibited; everything else requires a Plant Quarantine permit. This rewrites the landscape supply chain — you cannot simply order plants from a mainland nursery and have them shipped. Most plant material is grown locally on Oʻahu, Maui, Hawaii Island, or Kauai; specialty palms and ornamentals are imported under permit through Honolulu’s commercial inspection station at scale; and any landscaping operator who tries to import without permits faces civil penalties and confiscation. Act 236 of 2025 (signed June 27, 2025, effective July 1, 2025) renamed the former Hawaii Department of Agriculture (HDOA) to the Department of Agriculture and Biosecurity (DAB) and Act 250 of 2025 appropriated $26.6 million plus 44 new positions for biosecurity — meaning quarantine enforcement is increasing in 2026, not loosening.

The other defining items: Hawaii’s DCCA Contractors License Board requires a contractor’s license for any landscaping job over $1,500 under HRS Chapter 444 — most state thresholds are higher. The relevant specialty classification is C-27 Landscape (with sub-categories C-27a Landscape Contractor and C-27b Tree Trimming and Removal). Pesticide applicators must hold Commercial Applicator certification under HRS 149A through the DAB Pesticides Branch, including category-specific exams for Categories 3 (Ornamental and Turf) and 6 (Right-of-Way) most relevant to landscaping. Hawaii’s “Hawaii One Call Center” — Dig Safely Hawaii at 811 or 1-866-423-7287 under HRS 269E — requires 5 to 28 business days advance notice before any excavation, including planting, irrigation trenching, or post-hole digging, with substantial fines for non-compliance. And on top of all that, Hawaii’s worker-protection stack (workers’ comp at 1 employee, PHCA at 20+ hours/week, TDI, $16 minimum wage as of January 1, 2026) applies as it does for every other Hawaii service business.

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

Step 1: Form Your LLC and Register for GET

File Articles of Organization at the DCCA Business Registration Division via Hawaii Business Express for $50. Annual report: $15. Trade name registration optional at $50 for 5 years.

File Form BB-1 at Hawaii Tax Online for the $20 one-time GET license. GET applies to landscape labor and to any plant or material sales at 4.5% combined in all four counties through December 31, 2030. Maximum visible pass-on rate is 4.7120%.

Step 2: DCCA C-27 Landscape Contractor License — $1,500 Threshold

Hawaii’s contractor license requirement is broader than most states. Under HRS Chapter 444, any work valued over $1,500 (combined materials and labor) requires a contractor’s license issued by the DCCA Contractors License Board (CLB). This is much lower than mainland thresholds — California’s threshold is $500 (though stricter on apprenticeship), Texas has no threshold, and many states only license at $5,000-$10,000.

The relevant specialty classification for landscapers is the C-27 Landscape license with two subcategories:

• C-27a Landscape Contractor — landscape installation and maintenance, irrigation systems, hardscaping (walkways, retaining walls under specific limits), turf installation
• C-27b Tree Trimming and Removal — separate specialty for tree work, including ISA-style climbing and removal

Requirements:

• Experience: 4 years of supervisory experience in the C-27 trade (commonly substituted with documented apprenticeship + journey time, or partial substitution with a relevant degree)
• Trade exam: administered by PSI testing centers; covers C-27 scope, materials, methods, and code
• Business and Law exam: required for the responsible managing employee/officer; covers Hawaii contractor law, HRS 444, lien law, and licensing rules
• Bond: minimum $5,000 contractor bond from a Hawaii-authorized surety, posted before license issuance. The CLB can require higher bond amounts (up to $300,000) on a case-by-case basis based on financial strength and scope
• Application fee: approximately $415 (verify current at the time of application); biennial renewal
• Insurance: general liability and workers’ comp must be maintained continuously

Bond cost runs $100-$300/year for a $5,000 bond from most commercial surety markets. Operating without a required C-27 license on jobs over $1,500 is a misdemeanor on first offense and exposes you to civil penalties plus inability to enforce contracts. This is the single biggest licensing trap for new Hawaii landscape operators. “Maintenance only” work is sometimes argued to fall outside the threshold, but the line is fact-dependent — when in doubt, get the license.

Step 3: Pesticide Applicator Certification — DAB Pesticides Branch (HRS 149A)

If your landscape business applies any restricted use pesticide (Roundup-type concentrated formulations, professional-grade insecticides, herbicides, or any product labeled “Restricted Use”), you must hold Commercial Applicator certification through the DAB Pesticides Branch under HRS Chapter 149A.

• Core Commercial Applicator exam: $50, covers federal and Hawaii pesticide law, label reading, calibration, environmental safety, IPM principles
• Category exams: $25 per category. The relevant categories for landscapers:
  • Category 3 — Ornamental and Turf: the primary category for landscape operations covering ornamental plant care and turf management
  • Category 6 — Right-of-Way: for vegetation management along roadways, easements, and utility rights-of-way (less common for typical landscapers but required for certain commercial accounts)
  • Category 7A — Industrial, Institutional, Structural and Health Related Pest Control — applies to indoor or structural pest control work
• Recertification: every 3 years through continuing education credits (CET) approved by the DAB Pesticides Branch
• Pesticide Use Records: licensed applicators must maintain records of every restricted-use pesticide application for at least 2 years
• RUP Dealer License: separate $50 annual license required if you resell restricted-use pesticides to other licensed applicators (rare for typical landscapers)

Why this matters in Hawaii specifically: Hawaii has stricter restricted-use pesticide enforcement than most mainland states because of historical concerns about chlorpyrifos use in pineapple agriculture and ongoing concerns about glyphosate near schools and agricultural lands. The 2013-2017 chlorpyrifos litigation and Act 45 of 2018 (banning chlorpyrifos and disclosing pesticide use near schools) established Hawaii as one of the most restrictive states. Compliance audits are real.

Step 4: The Plant Quarantine Reality — HRS 150A and the DAB Rebrand

This is the single most consequential difference between landscaping in Hawaii and landscaping in any other state. Under HRS Chapter 150A, the DAB Plant Quarantine Branch (formerly under the Hawaii Department of Agriculture, now under the Department of Agriculture and Biosecurity following the July 1, 2025 rebrand under Act 236 of 2025) regulates the importation of every plant, plant part, fresh fruit or vegetable, soil, microorganism, and many growing media into the state of Hawaii.

What’s regulated under HRS 150A

• All live plants — even hardware-store-style annuals from a mainland source require inspection
• Soil — almost entirely prohibited from mainland import. This single rule completely changes the supply chain
• Many plants outright prohibited — e.g., banana, pineapple, citrus, sugarcane (depending on origin), and others on the Plant Quarantine prohibited list
• Plants requiring a permit: most ornamental palm species, specific cultivars, certain fruit trees — apply for a permit 30-90 days before shipment
• Inspection on arrival: all permitted plants must clear Honolulu’s commercial inspection station before release; some shipments are quarantined, fumigated, or rejected outright

Practical landscape supply chain

The vast majority of Hawaii landscape plant material is grown locally on Oʻahu, Maui, Hawaii Island, or Kauai. Hawaii’s commercial nursery industry — Plant Hawaiʻi members, Hawaii Florist and Shippers Association, and individual growers — produces most ornamentals, native species, palms, hedges, and turf for the local landscape market. Major Oʻahu nursery zones include Waimanalo, Waimea (windward Oʻahu), and parts of central Oʻahu. Big Island nursery production is concentrated around Hilo and Kona. Importing fancy specimens from California or Florida nurseries is possible under permit but takes 60-120 days and requires inspection compliance — most operators source locally.

Act 236 and Act 250 of 2025 — Biosecurity push

The July 1, 2025 rebrand of the Hawaii Department of Agriculture to the Department of Agriculture and Biosecurity (DAB) was paired with $26.6 million in new biosecurity funding under Act 250 of 2025, plus 44 new biosecurity positions. A Deputy to the Chairperson for Biosecurity position is being established effective January 1, 2027, with oversight of plant and animal quarantine inspections and invasive species interdiction. Practical effect for landscapers: quarantine enforcement is increasing in 2026, not loosening — and DAB’s increased inspection budget means previously quiet enforcement gaps are tightening.

Native Hawaiian and invasive species considerations

• Native plant preservation: several native Hawaiian species (e.g., ʻōhiʻa lehua, koa, certain ferns) carry their own preservation rules and may require Department of Land and Natural Resources (DLNR) coordination
• Coqui frogs, little fire ants, miconia, fountain grass: known invasive species that landscapers commonly encounter; reporting and treatment protocols apply
• ʻŌhiʻa Rapid Death (Ceratocystis): a fungal disease devastating ʻōhiʻa forests on Hawaii Island; movement of ʻōhiʻa wood and plant material between islands is regulated

Step 5: Worker-Protection Stack and Hawaii Wage Standards

Landscape work hits all of Hawaii’s worker-protection mandates:

• Workers’ compensation (HRS 386): required at 1+ employee. Landscape NCCI rates run higher than mainland averages — typically 4-7% of payroll because of injury frequency (chainsaw, ladder, sun exposure, machinery)
• Prepaid Health Care Act (HRS 393): 20+ hr/week employees require employer-paid health insurance with employer paying ≥50% of premium. Critical for crew-based landscape operations where most workers exceed 20 hours
• Temporary Disability Insurance (HRS 392): employee contribution capped at 0.5% / $7.50/week (2026)
• $16/hour minimum wage effective January 1, 2026 under Act 114 of 2022; $18/hour scheduled January 1, 2028
• Unemployment Insurance: register at uiclaims.hawaii.gov within 20 days of first hire; 2026 new-employer rate 2.40% on $64,500 wage base

Step 6: Hawaii 811 — HRS 269E Dig-Notice Rule

Hawaii’s “call before you dig” framework is the Hawaii One Call Center (HOCC), branded as Dig Safely Hawaii and reached at 811 or 1-866-423-7287. Under HRS Chapter 269E, anyone planning to excavate must provide notice 5 to 28 business days before digging. This rule applies to:

• Tree planting (root ball excavation)
• Irrigation trenching
• Drip line installation that disturbs soil at depth
• Post holes for fencing
• Concrete footings for retaining walls
• Any other earth disturbance below grade

Failure to provide notice exposes the excavator to civil penalties and full liability for any damaged utility line. After notice, the HOCC dispatches utility operators (electric, gas, water, sewer, telecom) to mark the locations on-site with color-coded paint and flags. Notification is free.

Practical compliance: Make 811 notice part of your standard pre-job checklist. Most successful Hawaii landscape operators submit 811 tickets the same day they sign the contract, so the 5-28 day window has elapsed by the time crews mobilize.

Step 7: Insurance — Commercial Auto, General Liability, Tools and Equipment

• Commercial auto insurance: $1,200-$2,500/year per truck. Required for any vehicle used commercially. Hawaii’s island geography keeps mileage modest but parking-lot-grade incidents in tight Honolulu and Maui resort areas are routine claim drivers
• General liability insurance: $600-$1,800/year for $1M/$2M typical limits. Required by virtually every commercial property manager, AOAO board, hotel vendor program, and homeowners’ association in Hawaii
• Tools and equipment coverage (inland marine): $200-$500/year covers theft and damage to mowers, trimmers, blowers, saws stored in trucks or at job sites. Hawaii landscape equipment theft from job-site trucks is meaningful, especially on Oʻahu
• Pesticide applicator coverage rider: if you spray, your GL policy may exclude pesticide-related claims unless you specifically add an applicator endorsement. Confirm with your broker

Hawaii Landscape Market: Where the Demand Is

Resort and hotel grounds maintenance: Hawaii’s tourism economy supports vast resort landscape operations — Hapuna, Mauna Lani, Mauna Kea, Hualālai (Big Island Kohala Coast); Kāʻanapali, Wailea (Maui); Waikīkī, Ko Olina, Turtle Bay (Oʻahu); Poʻipū, Princeville (Kauai). Resort landscape contracts run multi-year with high standards (golf-course-grade turf, signature palm collections, native plant gardens, sustainability programming). Vendor approval is rigorous — typically requires C-27 license, $1M-$5M GL, drug screening, and a track record. Margins are stable but competitive.

AOAO common-area landscaping: Hawaii’s high condominium-living rate (one of the highest in the U.S. on a per-capita basis) drives a huge ongoing market for AOAO common-area landscape contracts under HRS 514B. Lobbies, pool decks, parking garages, walkways, and shared garden areas need recurring care. Contracts are typically multi-year and bid through AOAO board RFPs — building a relationship with AOAO management companies (Hawaiiana, Associa Hawaii, Hawaii First Realty) is the path in.

Single-family residential and high-end estates: Kahala (Oʻahu), Lanikai (Oʻahu), Wailea Golf Estates (Maui), Hualālai Resort residential (Big Island), and Princeville (Kauai) have concentrations of high-end residential properties with substantial landscape budgets — multi-thousand-dollar weekly maintenance plus periodic redesign work. High touch, high quality expected.

Native and indigenous landscape design: Demand for native Hawaiian plant landscaping has grown substantially — driven by water conservation goals (Honolulu Board of Water Supply rebates), aesthetic and cultural preference, and resort sustainability programming. Operators who can specify and source ʻōhiʻa, koa (low-elevation cultivars), naupaka, ʻilima, and Hawaiian palms have a meaningful niche.

Lahaina rebuild (Maui): Following the August 2023 wildfires, the rebuild of historic Lahaina is producing landscape work at scale — site clearance, soil remediation, hardscape installation, fire-resistant planting design. Operators with C-27 licenses and crews on Maui have been at capacity through 2025-2026.

Coastal salt-tolerant species: Hawaii’s coastal exposure means salt-tolerant plant selection is critical. Naupaka, beach heliotrope, ʻakulikuli (sea purslane), and certain palm species are the workhorses; mainland landscape preferences (boxwoods, hydrangeas) often fail in Hawaii’s coastal salt-air conditions.

Frequently Asked Questions

Do I need a contractor’s license to start a landscaping business in Hawaii?

Yes, if any project (combined materials and labor) exceeds $1,500. Hawaii’s contractor license threshold under HRS Chapter 444 is one of the lowest in the U.S. The relevant specialty for landscape installation is the DCCA Contractors License Board’s C-27 Landscape license, with sub-categories C-27a (Landscape Contractor) and C-27b (Tree Trimming and Removal). Requirements include 4 years of supervisory experience, passing the trade exam, passing the Business and Law exam, posting at least a $5,000 contractor bond, and continuous workers’ comp and GL insurance. Application fee approximately $415, with biennial renewal. Pure mowing and maintenance contracts under $1,500 may be argued to fall outside the threshold, but the line is fact-dependent — when in doubt, get the license.

Can I import plants from the mainland for my Hawaii landscape projects?

Mostly no — and this is the single most consequential difference between landscaping in Hawaii and landscaping in any other state. Under HRS Chapter 150A, the Department of Agriculture and Biosecurity (DAB) Plant Quarantine Branch regulates the import of every plant, plant part, soil, microorganism, and many growing media into Hawaii. Soil is essentially prohibited from mainland import. Many plants are prohibited outright (banana, pineapple, citrus, sugarcane depending on origin). Permitted plants require a Plant Quarantine permit applied 30-90 days before shipment, plus inspection at Honolulu’s commercial inspection station on arrival. The practical reality: nearly all Hawaii landscape plant material is sourced from local Hawaii nurseries. Act 236 of 2025 renamed HDOA to DAB effective July 1, 2025, and Act 250 of 2025 added $26.6 million plus 44 positions for biosecurity — quarantine enforcement is increasing.

Do I need a pesticide applicator license in Hawaii?

Yes, if you apply any restricted-use pesticides commercially. Under HRS Chapter 149A, you must hold Commercial Applicator certification through the DAB Pesticides Branch. The exam costs $50 for the core test plus $25 per category. The relevant categories for landscape work are Category 3 (Ornamental and Turf) and Category 6 (Right-of-Way). Recertification is required every 3 years through continuing education credits approved by the DAB Pesticides Branch. You must also keep records of every restricted-use pesticide application for at least 2 years.

Do I have to call Hawaii 811 before digging on every job?

Yes, for any excavation. Under HRS Chapter 269E, you must notify the Hawaii One Call Center (Dig Safely Hawaii) at 811 or 1-866-423-7287 between 5 and 28 business days before any excavation — including planting trees (root ball excavation), irrigation trenching, post holes, or any other earth disturbance below grade. Notice is free. Failure to notify exposes you to civil penalties and full liability for any damaged utility line. Make 811 notice part of your standard pre-job checklist; most operators submit 811 tickets the same day they sign contracts so the waiting period is met by the time crews mobilize.

What was the HDOA-to-DAB rebrand and how does it affect landscapers?

Act 236 of 2025 (signed June 27, 2025, effective July 1, 2025) renamed the Hawaii Department of Agriculture (HDOA) to the Department of Agriculture and Biosecurity (DAB). Act 250 of 2025 appropriated $26.6 million plus 44 new positions for the biosecurity program, and a Deputy to the Chairperson for Biosecurity position is being established effective January 1, 2027. For landscape operators, this means: agency websites moved to dab.hawaii.gov; the Plant Quarantine Branch and Pesticides Branch now sit under DAB rather than HDOA; quarantine and import enforcement is increasing rather than loosening; and inspection capacity at the Honolulu commercial inspection station and Plant Quarantine field staff is expanding. The agency’s underlying authority under HRS 150A and HRS 149A is unchanged.

How much does it cost to start a landscaping business in Hawaii?

For an unlicensed solo operator doing mowing and maintenance under the $1,500 contract threshold, year-one costs run $4,200-$9,300 covering LLC ($50), GET ($20), GL insurance, commercial auto, and basic equipment. For a licensed C-27 operation with a crew, work truck, equipment trailer, pesticide applicator certification, and worker-protection stack (workers’ comp, PHCA, TDI, UI), year-one investment runs $34,000-$66,000+. The biggest cost differences from mainland operations: the C-27 license at the $1,500 threshold (most states are higher), the PHCA employer-paid health insurance share at $3,600-$6,000 per qualifying employee per year, and the Hawaii used-vehicle premium over mainland prices. Plant Quarantine import constraints generally do not add direct cost (because operators source locally), but they do add lead time when specifying specialty plants.
