Arizona Landscaping & Lawn Care Side Hustle: ROC Licensing, Pesticides, and Taxes

TL;DR

• Mowing and basic yard maintenance have a statutory ROC exemption. Arizona's contractor chapter "does not apply to" a person "who functions as a gardener by performing lawn, garden, shrub and tree maintenance." (A.R.S. § 32-1121(A)(16).) That does not cover installing irrigation, hardscape, or other improvement work the ROC lists under its specialty classifications.
• Hardscape and irrigation are licensed trades. The ROC's R-21 Hardscaping and Irrigation Systems (residential), C-21 (commercial), and CR-21 (dual) cover pavers, low walls, low-voltage landscape lighting, non-pool water features, and irrigation. Older dual licenses were titled "Landscaping and Irrigation Systems" and reclassify as Hardscaping and Irrigation Systems. (ROC, License Classifications.)
• Handyman exemption for small projects: casual or minor work under $1,000 total (labor + materials), no building permit, not split to dodge the limit, and every ad says "not a licensed contractor." Gas work is never covered. (A.R.S. § 32-1121(A)(14), (D).)
• Herbicide spraying has its own exemption—and hard limits. Lawn, garden, shrub, or tree maintenance that includes herbicides for weed management can skip PMD licensure unless you hit a trigger (restricted-use/"danger" labels, preemergents, advertising weed management as a primary service, more than five gallons of mix, a two-person spray crew, schools/child care, and more). (A.R.S. § 3-3613.)
• If you need a pest-management business license: Certified Applicator $55, Qualified Applicator $75, Business License $185, plus financial security of at least $500,000. (Arizona Department of Agriculture PMD fees; A.A.C. R3-8-103; A.R.S. § 3-3615.)
• ROC fees for a new R-21: $80 application + $270 license + $370 Residential Recovery Fund = $720 for a two-year specialty residential license, plus exams ($61 Statutes and Rules, $66 trade). Renewal is $540. (ROC, License and Renewal Fees.)
• Taxes: ADOR says Arizona generally doesn't tax professional services; selling plants, mulch, or soil as products is retail. Self-employment tax generally applies at $400+ net earnings. (ADOR; IRS.)

Who this guide is for

You want to mow lawns, trim shrubs, haul green waste, install drip irrigation, lay gravel or pavers, or build small hardscape features in Arizona as a side hustle. This page covers the licensing line between gardener maintenance and ROC-licensed hardscape/irrigation, when herbicide work needs a pest-management license, city paperwork, and taxes.

We don't publish income claims, route prices, or "typical" yard earnings. Those aren't something we can verify on an official source.

Which rules apply to which kind of yard work

Step 1: Start with the gardener exemption

A.R.S. § 32-1121 lists people the contractor chapter does not apply to. Paragraph (A)(16) covers "a person who functions as a gardener by performing lawn, garden, shrub and tree maintenance." (A.R.S. § 32-1121(A)(16).)

How we read that for a side hustle (not a ruling): weekly mowing, edging, blowing, raking, basic shrub and tree trimming, and similar upkeep fit the ordinary meaning of "lawn, garden, shrub and tree maintenance." The statute does not say the exemption covers installing irrigation systems, building retaining walls, pouring non-loadbearing concrete, or other work the ROC places in R-21 / C-21 / CR-21.

If your ad or proposal mixes maintenance with hardscape or irrigation, treat the improvement work under the ROC rules below. When in doubt, call the ROC at (602) 542-1525 or 1-877-692-9762 and keep a written note of what you asked and what they said. (ROC, Contact Us.)

Working as a W-2 employee of a licensed contractor also doesn't require your own ROC license. (A.R.S. § 32-1121(A)(11).) Being paid on a 1099 is different; the IRS looks at control and the relationship of the parties. (IRS, Independent contractor or employee?)

Step 2: Know when R-21 / C-21 / CR-21 applies

The ROC does not publish a separate "lawn mowing" classification. The specialty class that covers most paid landscape construction work is Hardscaping and Irrigation Systems:

(ROC, License Classifications, checked November 6, 2026.)

What these licenses do not allow (with limited fire-feature exceptions): new electrical service panels, gas or plumbing lines, blasting, covered outdoor kitchens, gazebos, room additions, swimming pools, pool deck coatings, concrete driveways, load-bearing walls, or perimeter fencing. (ROC, License Classifications.)

How we read that for a side hustle:

• Installing or repairing irrigation, drip lines, backflow devices, or landscape lighting is inside the R-21 scope.
• Pavers, gravel paths, low decorative walls, and small water features are inside the R-21 scope.
• Mowing and pruning alone sit under the gardener exemption above, not under R-21's "install, alter, and repair" language—but the ROC's website doesn't publish a FAQ that maps every maintenance task, so confirm borderline jobs (for example, major tree removal, grading, or large plant installs billed as construction) with the ROC before you advertise them.

Step 3: The under-$1,000 handyman exemption

If you don't hold an ROC license, A.R.S. § 32-1121(A)(14) exempts casual or minor work when the aggregate contract price—including labor, materials, and all other items—is less than $1,000. The ROC's summary: "if labor and materials exceed $1,000 OR a permit is required (regardless of the price of labor and materials), then a license is required." (A.R.S. § 32-1121; ROC, License Classifications.)

The exemption doesn't apply when:

1. The work needs a local building permit.
2. The work is part of a larger operation, or jobs are split under $1,000 to evade the law.
3. You advertise without the exact words "not a licensed contractor." (A.R.S. § 32-1121(A)(14); ROC news release, April 6, 2021.)

Gas is always out. None of the dollar exemptions cover connecting to natural gas, propane, or other gaseous fuel. (A.R.S. § 32-1121(D)(2).)

A small drip-line repair under $1,000 may fit; a $2,400 paver patio does not. Count everything in the total. Our Arizona handyman exemption guide covers the exemption in more detail.

Step 4: Getting an R-21 license (if you need one)

The ROC licenses the business, not just the person. A sole proprietorship, partnership, LLC, or corporation can apply with a qualifying party who has the experience, knowledge, and skills for the classification. Everyone on the application must be at least 18. An LLC or corporation must be in good standing with the Arizona Corporation Commission first. (ROC, Applying for a License; ROC, License Classifications.)

Typical steps (ROC, Applying for a License):

1. Name a qualifying party who meets the classification's experience requirements (check the ROC's License Classification Requirements document for R-21).
2. Pass exams with at least 70%: the online AZ Statutes and Rules Training Course and Exam (SRE) through Gmetrix, and the trade exam through PSI, unless you qualify for a waiver.
3. Complete background checks for every person named on the application.
4. Post a license bond (surety, cash, or Arizona-bank certificate of deposit).
5. Pay the fees and submit the application. Licensing staff: 877-692-9762 or Licensing@roc.az.gov.

Fees for a two-year license (ROC, License and Renewal Fees, effective 7/1/2014, checked November 6, 2026):

Exam fees (paid to vendors, not included in the ROC totals): $61 SRE (Gmetrix) and $66 trade exam (PSI). (ROC, License and Renewal Fees.)

Bond amounts (ROC, Bond Information):

Dual licenses combine the residential and commercial amounts. Residential contractors also pay into the Residential Recovery Fund or post a $200,000 surety or cash bond instead. (ROC, Bond Information.) What a surety company charges you isn't set by the ROC.

Fee waiver. The ROC waives the initial license application fee for a first-time Arizona sole proprietor who is an active-duty service member's spouse, an honorably discharged veteran discharged not more than two years earlier, or someone whose family income doesn't exceed 200% of the federal poverty guidelines. Residential and dual applicants still pay the Recovery Fund assessment. (ROC, License and Renewal Fees; A.R.S. § 41-1080.01.)

Once licensed, put your ROC number on ads, letterheads, and customer documents (with a limited web-address exception for some media). (ROC news release, April 6, 2021.)

Step 5: Herbicides, insecticides, and the landscaper exemption

Arizona's Pest Management Division (PMD) at the Arizona Department of Agriculture licenses structural pest-management businesses and applicators. "Structural" use includes weeds in lawns and pests in ornamental shrubs and trees near structures. (Arizona Department of Agriculture, Pest Management FAQs.)

The landscaper herbicide exemption. A.R.S. § 3-3613 says PMD licensure and registration requirements do not apply to a person who conducts lawn, garden, shrub, or tree maintenance and applies herbicides for weed management—except if the person:

1. Uses herbicides labeled "restricted use" or "danger"
2. Uses sterilants or preemergent herbicides
3. Offers weed management as the primary service or advertises weed management services
4. Uses application equipment that collectively holds more than five gallons of total mixed liquid herbicide at an address or project on the same day
5. Uses more than twenty-five pounds of nonliquid herbicide at an address or project on the same day
6. Uses or is part of a crew of two or more herbicide applicators at an address or project on the same day
7. Uses an herbicide at a school or child care facility
8. Uses an herbicide at an address without performing lawn, garden, shrub, or tree maintenance there the same day

(A.R.S. § 3-3613(B).)

Records still required when exempt. Exempt landscapers must give each customer treatment records (address, date, product name, amount, applicator name) and keep the same information for at least six months. Missing records bring warnings and civil penalties. (A.R.S. § 3-3613(C)–(D).)

If the exemption doesn't fit (for example you advertise lawn weed control, use preemergent, or spray insecticides for hire), you generally need the PMD path:

(Arizona Department of Agriculture, Pest Management Fees / FAQs; A.A.C. R3-8-103; A.R.S. § 3-3615. Confirm current fees on the department's fee schedule before you apply.)

Two-year renewals on the department fee schedule list Certified Applicator $99, Qualified Applicator $135, and Business $333. (Arizona Department of Agriculture, Pest Management Fees.) Ornamental and turf is the category that matches most lawn and shrub spray work. (Arizona Department of Agriculture, Pest Management FAQs.)

Insecticides and other pesticides are not covered by the § 3-3613 herbicide landscaper exemption. If you spray for bugs, mites, or other pests for hire, assume PMD licensing applies unless another statute exempts you—confirm with PMD before you advertise.

Step 6: City business license, home occupation, and equipment storage

City licenses. Some Arizona cities require a general business license for home businesses and some don't. Phoenix has no general business license. Tucson, Mesa, Scottsdale, and many others do. See our Arizona business license guide and the city-by-city guides for the East Valley, West Valley, Flagstaff, Prescott, Sedona & Yuma Business Licenses, and Tucson, Oro Valley, Marana, and Sahuarita.

Home occupation / equipment. Parking trailers, storing mowers and chemicals, and having clients pick up at your house can trigger zoning and HOA rules even when no state license is required. See Arizona home occupation permits.

Step 7: TPT, income tax, and self-employment tax

Arizona TPT (sales tax).

• ADOR says "Arizona generally does not tax professional services." A service business with no other taxable activity often doesn't need a TPT license. (ADOR, Conducting Taxable Retail Activity.)
• Maintenance and repair by unlicensed people: the prime contracting classification "does not include any work or operation performed by a person that is not required to be licensed by the registrar of contractors pursuant to section 32-1121." (A.R.S. § 42-5075(A).)
• Licensed contractors doing MRRA work: ADOR says you generally won't need a TPT license "if you only perform MRRA work and you are required to pay tax when you purchase your materials." (ADOR, Contracting FAQs; ADOR, MRRA Contracting.)
• Retail of plants, mulch, soil, rock, or tools sold as products is different from labor. A.R.S. § 42-5061 excludes professional or personal service businesses that transfer tangible personal property only as an "inconsequential" element; selling bags of mulch or nursery stock the customer takes home is typically retail. (A.R.S. § 42-5061; ADOR.)
• ADOR's state TPT license fee is $12 per location, and cities may add their own. (ADOR, TPT License.)

Keep service and product income separate on invoices. Our Arizona TPT License guide explains registration.

Income and self-employment tax. If you run your own routes, profit is self-employment income. You generally owe self-employment tax and file Schedule SE if net earnings are $400 or more. The rate is 15.3% (12.4% Social Security and 2.9% Medicare). (IRS, Self-Employment Tax.) Track mileage, fuel, equipment, disposal fees, and supplies. See Side Hustle Taxes in Arizona and the free Arizona side hustle tax set-aside calculator.

Penalties (hedged to the statutes)

• Acting as a contractor without a required license is a class 1 misdemeanor, with a first-offense fine of not less than $1,000. (A.R.S. § 32-1164.)
• Advertising without "not a licensed contractor" when you rely on the handyman exemption exposes you to consumer-fraud enforcement. (A.R.S. § 32-1121(C).)
• Using herbicides outside the § 3-3613 exemption without PMD licensure can bring cease-and-desist orders and civil penalties up to $1,000 (first) or $2,000 (later). (A.R.S. § 3-3613(E).)

Insurance (hedged on purpose)

You'll be on other people's property with blades, chemicals, and trailers. Whether you need general liability or commercial auto is a question for a licensed Arizona insurance agent. We don't sell insurance or recommend carriers. An LLC can separate some personal and business assets, but it doesn't replace an ROC or PMD license where one is required. See How to Start an LLC in Arizona.

A simple decision path

1. Mow, edge, blow, and trim only? Read A.R.S. § 32-1121(A)(16). Skip advertising hardscape or irrigation you aren't licensed for.
2. Want to spot-spray weeds while you maintain the yard? Stay inside A.R.S. § 3-3613, keep treatment records, and don't advertise weed management as your primary service.
3. Small hardscape or irrigation jobs? Keep each project under $1,000 all-in, skip anything needing a permit or involving gas, and put "not a licensed contractor" on every ad—or get licensed.
4. Regular irrigation or hardscape work? Apply for R-21 (residential), C-21 (commercial), or CR-21 (both): exams, bond, background checks, and $720 in ROC fees for a new R-21.
5. Preemergent, restricted-use products, or advertised weed/pest control? Plan on PMD applicator + business licensing and $500,000 financial security.
6. Selling plants or mulch? Ask ADOR whether you need a TPT license.
7. Not sure? Call the ROC at (602) 542-1525, check PMD through the Arizona Department of Agriculture, or try our Arizona side hustle license & permit checklist.

Frequently asked questions

Do you need a license to mow lawns in Arizona? Arizona's contractor chapter does not apply to a person who functions as a gardener performing lawn, garden, shrub and tree maintenance. (A.R.S. § 32-1121(A)(16).) You may still need a city business license, and herbicide or hardscape work has separate rules.

What is an R-21 license in Arizona? R-21 Hardscaping and Irrigation Systems is the ROC's residential specialty license for installing, altering, and repairing hardscape (pavers, low walls, landscape lighting, non-pool water features) and irrigation systems within the published scope. C-21 is commercial; CR-21 is both.

How much does an Arizona landscaping contractor license cost? A new specialty residential (R-21) license costs $720 in ROC fees for two years ($80 application, $270 license, $370 Residential Recovery Fund), plus $61 for the Statutes and Rules exam and $66 for the trade exam. You'll also need a license bond ($4,250 for a residential specialty contractor expecting under $375,000 a year). Renewal is $540.

Can I spray Roundup without a pesticide license in Arizona? Possibly, if you are doing lawn, garden, shrub, or tree maintenance, the product isn't labeled "restricted use" or "danger," you aren't using a preemergent or sterilant, you don't advertise weed management as a primary service, and you stay under the gallon, pound, crew, and site limits in A.R.S. § 3-3613. Keep customer treatment records. Confirm with the Arizona Department of Agriculture's Pest Management Division for your exact products and ads.

Do I charge sales tax for lawn care in Arizona? ADOR says Arizona generally doesn't tax professional services. Selling plants, mulch, or soil as products can be taxable retail. Confirm your setup with ADOR.

Is planting trees considered contracting in Arizona? The gardener exemption covers "lawn, garden, shrub and tree maintenance." Large installs, grading, or work that looks like an improvement can cross into contracting. Ask the ROC about your specific services before you advertise.
