How to Start a Landscaping Business in Iowa (2026)

Last updated: February 25, 2026

Starting a landscaping business in Iowa is relatively straightforward if you only provide mowing, trimming, planting, and non-chemical services. However, if you apply any pesticides (herbicides, insecticides, fungicides) to a client’s property for hire, you need licensing from the Iowa Department of Agriculture and Land Stewardship (IDALS). Iowa requires both a Commercial Pesticide Applicator Business License ($25/year per location) and at least one employee certified as a Commercial Pesticide Applicator ($75 for a 3-year certification). Starting in January 2026, Iowa changed its pesticide applicator exam requirements – the closed-book proctored exam format is now required. This guide covers all requirements for starting a compliant Iowa landscaping business.

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

Step 1: Form Your Iowa LLC

File a Certificate of Organization with the Iowa Secretary of State via Fast Track Filing ($50 online, 1 business day). Apply for a free federal EIN at IRS.gov.

Step 2: Determine Your Pesticide Licensing Needs

Under Iowa Code Chapter 206, any person or business that applies pesticides to the land or property of another person for hire must be licensed and certified by IDALS.

You need pesticide licensing if you:

Apply herbicides (weed killers) to client lawns or landscapes
Apply insecticides for pest control in landscaping
Apply fungicides to client plants, trees, or turf
Apply any product claiming to control, kill, or repel pests on client property

You generally do NOT need pesticide licensing if you:

Only mow, trim, edge, and maintain lawn without any chemical applications
Only plant, mulch, and do non-chemical landscaping work
Apply fertilizers that make no pesticide claims

Note: Many landscapers choose to get licensed even if not initially required, since clients often request weed control services and the license allows significant business expansion.

Step 3: Get Certified as a Commercial Pesticide Applicator

The certification is administered by the Iowa Department of Agriculture and Land Stewardship (IDALS) Pesticide Bureau.

Relevant categories for landscapers:

Category	Covers
3O – Ornamental Pest Control	Trees, shrubs, flowers, ornamentals outside greenhouses
3T – Turf Pest Control	Turf grasses, lawn care
3OT – Ornamental and Turf	Combined category (covers both above)

Exam process (effective January 2026):

Two exams required: (1) Iowa Core exam (50 questions) covering pesticide safety, laws, and general principles; and (2) a category-specific exam (35 questions)
Both are now closed-book, proctored exams (the unproctored private applicator option ended December 31, 2025)
Study materials available from Iowa State University Extension: extension.iastate.edu/psep
Contact IDALS to schedule exams: 515-281-5601 | iowaagriculture.gov

Certification fee: $75 for a 3-year certification period

Renewal options (every 3 years):

Re-take the exams, OR
Attend approved Continuing Commercial Instruction Courses (C-CIC); fee is typically $45 per session for most categories

Step 4: Get the IDALS Commercial Pesticide Applicator Business License

In addition to having an individually certified applicator on staff, your business must hold a separate Commercial Pesticide Applicator Business License:

Annual fee: $25 per business location
Expiration: December 31 of each year; renewal notifications sent by IDALS
Insurance requirement: Minimum $100,000 per occurrence property damage and public liability insurance (OR $100,000 each occurrence / $300,000 aggregate)
Apply through IDALS: iowaagriculture.gov/pesticide-bureau | 515-281-5601

Step 5: Get Local Business Permits

Check whether your city or county requires a local business license. Iowa has no statewide general business license. Use the free IASourceLink License Navigator to identify requirements for your location. If operating from home, check whether your city requires a home occupation permit.

Step 6: Get Business Insurance

General Liability Insurance

Protects against property damage (damaged sprinkler system, broken windows, plant death from chemical misapplication) and bodily injury claims
Required by IDALS: minimum $100,000/occurrence for pesticide applicator business license
Recommended: $1 million per occurrence for most commercial accounts
Typical cost: $1,500-$3,000/year for small landscaping companies

Commercial Auto Insurance

Required if using vehicles for business. Personal auto policies exclude commercial use. If you pull a trailer with equipment, ensure the trailer is covered.

Workers’ Compensation Insurance

Required with your first employee in Iowa. Landscaping is a high-risk category (outdoor work, equipment hazards, chemical exposure, heat illness). Iowa requires coverage immediately upon hiring.

Do I need a license to start a landscaping business in Iowa?

If you only provide mowing, trimming, planting, and non-chemical services, you do not need a pesticide applicator license. However, if you apply any pesticides (herbicides, insecticides, fungicides) to client property for hire, you need: (1) an individual Certified Commercial Pesticide Applicator certification from IDALS ($75/3 years); and (2) a Commercial Pesticide Applicator Business License ($25/year from IDALS).

Yes, with your first employee. Iowa requires workers’ compensation as soon as you hire any employee for most industries.

Purchase coverage through a private insurer or Iowa’s assigned risk pool.

You need: (1) General liability insurance – IDALS requires minimum $100,000/occurrence for your pesticide business license; $1 million is recommended for commercial accounts; (2) Commercial auto insurance for business vehicle use; and (3) Workers’ compensation insurance when you hire employees. Total insurance costs typically run $3,000-$6,000/year for a small operation.

Iowa commercial pesticide applicator certifications are valid for 3 years. To renew, you can either: (1) re-take and pass the Core exam and category-specific exam; or (2) attend approved Continuing Commercial Instruction Courses (C-CIC) from IDALS.
