Arizona landscape contractor license: what the Registrar of Contractors covers, and what it leaves to gardeners

Arizona's Registrar of Contractors has a license class for pavers, walls to three feet and sprinklers, and on the pages we read, no class that names planting. The statute exempts "a person who functions as a gardener by performing lawn, garden, shrub and tree maintenance", with no dollar figure attached. Everything else a landscape crew does gets measured against that class list. The ROC's own website sat behind a bot check when we tried it, so the ROC pages here are archived copies. We read the statutes live on azleg.gov on October 1, 2026, and the rules on Cornell's site. The last section says which source is which.

Gardener work is exempt, and small jobs are exempt only with a disclaimer

The gardener exemption is paragraph 16 of A.R.S. 32-1121. It covers maintenance and says nothing about installing. The small-job exemption, paragraph 14 of the same section, has strings attached. Labor and materials together must come in under $1,000. The work must be casual or minor, with no local building permit required, and it can't be a slice of a larger project or a big job cut into small contracts. Any advertising for it has to say "not a licensed contractor", or the exemption is gone and the statute points to consumer-fraud prosecution.

A job priced at exactly $1,000 is not under the line. The ROC states the test from the other side, in different words: a license is generally required when labor and materials exceed $1,000 or a permit is required. "Exceed" and "less than" part ways at exactly $1,000, and the statute controls.

The class list has hardscape and irrigation, and the old landscaping name is gone

The ROC issues commercial (C), residential (R) and dual (CR) licenses, and the number that fits a landscape company is 21, Hardscaping and Irrigation Systems. On the ROC's page, a residential R-21 licensee may install, alter and repair:

• non-loadbearing concrete, and uncovered patios, walkways and driveways in brick, stone, pavers or gravel;
• wooden decks up to 29 inches above grade, garden walls and fences up to six feet, retaining walls up to three feet;
• free-standing fire pits and barbecues, with electric, plumbing and gas subcontracted out;
• low-voltage landscape lighting and water features not attached to a pool;
• irrigation systems with the 120-volt-or-less wiring, potable water connections and backflow devices they need;
• residential misting systems up to 1,000 PSI, and uncovered outdoor kitchens.

The commercial C-21 class gets the same list minus the misting systems and outdoor kitchens, per the rule text. Neither class allows gazebos, covered kitchens, new electrical panels, gas or plumbing lines, concrete driveways, load-bearing walls or perimeter fencing. A note on the ROC page says existing CR-21 Landscaping and Irrigation Systems licenses are reclassified as Hardscaping and Irrigation Systems, so the word "landscaping" has dropped out of the class name.

Planting, sod and trees fall in a gap these pages don't close

None of the ROC's class descriptions lists planting, sod, turf or trees as work, and that absence is all this page's planting claim rests on. The statute defines a contractor as anyone who offers to build, alter, repair or improve a building, excavation or other structure, project, development or improvement. A $6,000 planting bed is arguably an improvement, which is our reading and not the ROC's, and we found no ROC page that says so or says otherwise. Put the question to the ROC in writing: does installing new plants, sod or trees on a customer's property for more than $1,000 require a contractor license, and in which class?

A qualifying party with four years, and two exams

Every license names a qualifying party, who is an owner or regularly employed by the business. Before issue, that person needs four years of trade experience, two of them in the last ten, and technical training can replace up to two of the four. The ROC can waive the exam for anyone who was a qualifying party in the same class within the previous five years.

One exam covers statutes and rules, taken online for $61 paid to GMetrix. The other is the trade exam, $66 paid to PSI, per the ROC fee page. The passing grade is 70%. Fail and you wait 30 days, fail again and wait 30 more, and every later try waits 90. Everyone named on the application must be 18 or older, and an LLC or corporation has to be in good standing with the Corporation Commission.

A new R-21 costs $720, plus a $4,250 or $7,500 bond

The fees below cover a two-year license, and the ROC's page is headed "Effective 7/1/2014". The statute caps a specialty residential application plus license at $350, which is what the R-21 row adds up to. The bond is set by the volume of work you expect in Arizona, per the ROC bond table.

Class	Application	License	Recovery fund	New total	Renewal	Bond
R-21 (specialty residential)	$80	$270	$370	$720	$540	$4,250 under $375,000 a year, $7,500 at $375,000 or more
C-21 (specialty commercial)	$100	$480	none	$580	$480	$2,500 at $150,000 a year or less, $7,000 over that up to $500,000
CR-21 (specialty dual)	$100	$380	$370	$850	$650	residential and commercial bonds added

Residential and dual licensees pay into the Residential Recovery Fund or post a $200,000 bond instead. Exam fees come on top. All of these figures come from an archived copy of the fee page dated June 19, 2026.

Numbers on every bid, and no standing to sue

A.R.S. 32-1124 requires the license number, preceded by the letters ROC, on written bids, estimates and advertising, unless an online ad links to a page that shows it. Working without a license is a Class 1 misdemeanor with a fine of at least $1,000 for a first offense and $2,000 after that. An unlicensed contractor also can't sue for the money: the statute requires proof of a license at the time of the contract before a payment suit goes anywhere.

The bond is not the policy

The ROC pages we read ask for exams, background checks, ID, a bond and fees. They list no general liability certificate. A bond answers the claims the statute lists, and it doesn't pay for a customer's injury or a broken line. A sprinkler or paver job leaves completed-operations exposure behind, which the landscaping insurance page walks through. The gardener exemption protects the maintenance route, and the general liability guide is written around it. Other states' sprinkler rules sit side by side on the irrigation license hub. HOAs and property managers will want a certificate of insurance even though the ROC doesn't.

How we read Arizona

The ROC site showed a human-verification check to our browser tools and to curl, and we did not try to get past it. The ROC pages cited above are Internet Archive copies dated June 19, July 26 and August 17, 2026. The Legislature's statute site loaded today, so the statutes are live copies read October 1, 2026. The administrative rules came from Cornell's Legal Information Institute the same day. We did not read the ROC's class requirements page, because its archived copy was a block page. We found no figure for liability insurance because we found no requirement.
