Arizona · Landscaping licensing · official-source guide
The Arizona Registrar of Contractors licenses landscaping at state level, by classification, under Title 32, Chapter 10. Installation work such as grading, planting, hardscape and underground irrigation needs that license. Section 32-1121 exempts gardeners doing lawn, garden, shrub and tree maintenance. The headline requirement is a qualifying party with four years of experience plus a written examination.

Landscaping is licensed by the state, not by the city. The Arizona Registrar of Contractors issues contracting licenses under Title 32, Chapter 10 of the Arizona Revised Statutes. Section 32-1151 makes it unlawful to engage in the business of, submit a bid for, act in the capacity of, or purport to have the capacity of a contractor without a license in good standing, unless an exemption applies. The same section says that pulling a permit from a government agency, or employing a person on a construction project, is accepted in court as prima facie evidence that a contract exists. That matters when a crew grades a yard, sets block, or trenches an irrigation main without a license and later argues there was no contract. The registrar is required by section 32-1104 to keep an office in Phoenix, to maintain a complete indexed record of every application and license issued, renewed, cancelled, revoked or suspended for at least seven years, and to make rules including minimum standards for good and workmanlike construction. Landscaping has one feature that most construction trades do not. Section 32-1121 exempts a person who functions as a gardener by performing lawn, garden, shrub and tree maintenance. Maintenance mowing, pruning and cleanup crews therefore operate outside the licensing chapter entirely. Installation crews do not. A Phoenix or Tucson company that sells both maintenance routes and installation projects is sitting on both sides of that line at the same time, and only the installation side needs the state license.
The exemption in section 32-1121 covers a person who functions as a gardener by performing lawn, garden, shrub and tree maintenance. It does not define installation, so the practical boundary is best read next to the tax statute, which draws the same line in detail. Section 42-5075 treats lawn maintenance as a service and lists what counts: mowing and edging, weeding, repairing sprinkler heads or drip irrigation heads, seasonal replacement of flowers, refreshing gravel, dethatching, seeding winter lawns, leaf and debris collection, tree or shrub pruning or clipping, garden and gravel raking, and applying pesticides and fertilizer materials. The same section says gross income from landscaping activities is taxable as prime contracting, and defines landscaping activities as installing lawns, grading or leveling ground, installing gravel or boulders, planting trees and other plants, felling trees, removing or mulching tree stumps, removing other imbedded plants, building irrigation berms, installing railroad ties, and installing underground sprinkler or watering systems. Read the two lists together and the shape of the job becomes clear. Pulling a dead shrub and replacing a drip emitter is maintenance. Installing the drip system, regrading for drainage, or setting boulders is contracting. Section 32-1121 also carries a separate exemption for casual or minor work under $1,000 including labor and materials, which does not apply where a building permit is required, where the work is part of a larger operation, or where the person advertises without the words not a licensed contractor in the advertisement.

Section 32-1122 gives the registrar the job of classifying and qualifying applicants and of establishing written examinations. The application itself must designate the classification being sought, so you pick the scope of work before anything else happens. The statutory architecture appears most plainly in the fee and bond sections. Sections 32-1126 and 32-1152 recognize general residential contracting and its subclassifications, general commercial contracting and its subclassifications, general dual licensed contracting, specialty residential contracting, specialty commercial contracting, and specialty dual licensed contracting. Landscaping and irrigation installation is a specialty scope rather than a general building scope, so the fee tier, the bond tier, and the examination all follow the specialty track. The residential and commercial split is the decision that costs money. A residential license covers work on dwellings. A commercial license covers everything else. A dual license covers both and is priced and bonded as two classifications carried on one bond, with the bond amount for each side set from the volume of work on that side. A landscaping company that installs for homeowners in Mesa and also bids school and HOA common area work in Scottsdale needs the dual license or two separate licenses, not one residential license stretched to cover both. The registrar may also change a license classification in the case of a title reclassification, with or without a bond rider to continue liability on the existing bond.
Arizona licenses the business, and the business qualifies through a person. Section 32-1122 requires the application to name a qualifying party, along with the owners of twenty-five percent or more of the stock or beneficial interest, the officers and directors of a corporation, the managers or members of a limited liability company, all partners of a partnership, and all trustees of a trust. The applicant must attest that it has complied with the workers compensation statutes and rules, and if it is required to carry workers compensation under Title 23, Chapter 6, the attestation must state the policy number or come with proof of self insurance. Any change in that information must be reported to the registrar within thirty days. Everyone named on the license must not have contracted without a license or committed an act that would be grounds for suspension or revocation, and a person convicted of contracting without a license cannot obtain a license for one year after the last conviction. A license denied, refused or revoked within the prior year also blocks an application, although the registrar may excuse the circumstances if no unremedied hardship, danger or loss to the public resulted. Under section 32-1125 a licensee may apply in writing for exemption from carrying a qualifying party, but only by showing five years of continuously valid licensure, no transfer of fifty percent or more of its stock or beneficial interest, and no unremedied violation.

Before the registrar issues a license, the qualifying party has to clear two gates under section 32-1122. The first is experience. The qualifying party must have at least four years of practical or management trade experience, at least two of which fall within the last ten years, dealing specifically with the type of construction for which the license is sought, or its equivalent. Technical training at an accredited college or university, or in a manufacturer accredited training program, may substitute for part of that, but credited technical training may never exceed two years of the four. For a landscaping applicant that means irrigation, grading and hardscape work history has to line up with the classification on the application. Horticulture coursework helps, but it cannot carry more than half the requirement. The registrar may reduce the four year requirement if custom and usage in the particular craft show it is excessive, and must waive the work experience documentation and verification if the records show the qualifying party already is or has been a qualifying party in the same classification in Arizona. The second gate is a written examination, taken not more than two years before application. It covers the kind of work being licensed, the state building, safety, health and lien laws, administrative principles of the contracting business, the registrar rules, construction plans and specifications, standards and techniques of the craft, and a general understanding of related trades. The registrar maintains multiple versions of each examination and waives the examination for a returning qualifying party in the same classification.

Arizona contracting licenses run on a two year cycle, and section 32-1126 sets ceilings rather than exact prices. For an original biennial license the application and license fee is not more than $350 for specialty residential contracting, not more than $1,000 for specialty commercial contracting, and not more than $1,350 for specialty dual licensed contracting. The general classifications are higher: not more than $500 for general residential, not more than $1,500 for general commercial, and not more than $2,000 for general dual licensed contracting. Biennial renewal is capped lower. Specialty residential renewal is not more than $270, specialty commercial not more than $900, and specialty dual not more than $1,170, while general residential renewal is capped at $320, general commercial at $1,000, and general dual at $1,320. An annual renewal granted under section 32-1123.01 is one half of the biennial renewal fee. The registrar may set separate fees for examinations, reexaminations, application processing, changes of qualifying party and name change approvals, and may contract with private testing services and have the examination fee paid directly to them. Missing the renewal deadline carries a $50 penalty. One more charge applies to the residential side. A person applying for or renewing a residential contracting license pays an assessment of not more than $600 during the biennial license period for the residential contractors recovery fund, unless the contractor instead posts the additional bond described in section 32-1152.
Sourcesazleg.gov
Section 32-1152 requires a surety bond or cash deposit before an original license is granted, and no license renews unless the bond or deposit is in full force. Amounts are fixed by the registrar within statutory brackets set by classification and by estimated annual volume of construction work. A specialty residential contractor furnishes a bond or cash deposit of not more than $7,500 and not less than $1,000. A general residential contractor furnishes not more than $15,000 and not less than $5,000. Specialty commercial contractors are bracketed by volume: not less than $2,500 and not more than $7,500 above $150,000 of annual volume, not less than $5,000 and not more than $17,500 above $500,000, not less than $7,500 and not more than $25,000 above $1,000,000, not less than $17,500 and not more than $37,500 above $5,000,000, and not less than $37,500 and not more than $50,000 at $10,000,000 or more. A specialty dual licensed contractor posts a single bond carrying an amount for each classification, with the commercial side set by commercial volume and the residential side by residential volume. Residential and dual licensed contractors must also either furnish an additional bond or cash deposit of $200,000 solely for actual damages suffered by claimants, or participate in the residential contractors recovery fund and pay the assessment. The bond must be written by a surety authorized to transact surety business in Arizona, or replaced by a cash deposit with the state treasurer.
Sourcesazleg.gov
Chapter 10 does not set a general liability insurance minimum for a landscaping contractor. The bond or cash deposit under section 32-1152 is the financial instrument the state requires, and general liability coverage is a commercial and contractual question rather than a licensing threshold. Workers compensation is different. Section 32-1122 requires the applicant to attest, at application and at every renewal, that it has complied with the statutes and rules governing workers compensation insurance, and where coverage is required under Title 23, Chapter 6, the attestation must carry the policy number or be accompanied by proof of self insurance. That attestation is a continuing condition of holding the license, not a one time filing, and a change must be reported within thirty days. Where a landscaping company crosses into licensed pesticide work the financial requirement becomes explicit and large. Section 3-3615 requires a pest management business license application to include proof of financial security, in the form of a money deposit, liability insurance, self insured retention, a surety bond or a certified check protecting persons who may suffer bodily injury or property damage from the licensee operations. The amount must be at least $500,000 and must stay at or above that figure at all times during the licensing period. If the security drops below $500,000 the director suspends the business license until the minimum is restored. Insurers must hold a certificate of authority in Arizona or be permitted to transact surplus lines insurance here.

A contracting license is issued biennially and, under section 32-1125, is suspended by operation of law on the next business day following its renewal date. A renewal application mailed or received on or before the renewal date, with a valid bond or cash deposit on file and the fee paid, lets the licensee keep operating until the renewal license is actually issued. A license suspended for failure to renew can be reactivated within one year by filing the application and paying the renewal fee plus a $50 fee. Past one year the license is gone and a new application is required. The registrar may also refuse to renew if the licensee has committed any act listed in section 32-1154. What Chapter 10 does not impose is classroom hours. Renewal turns on the fee, the bond, and the attestations required by section 32-1122, including the workers compensation attestation. There is no statutory continuing education requirement for a landscaping contractor license. The pesticide side works differently. Section 3-3618 has the director set application and renewal fees by rule for business licenses, branch office and branch supervisor registrations, qualifying party registrations, applicator certifications and qualified applicator certifications, so those amounts live in rule rather than in statute. Section 3-3621 lets the director require an individual to take supplemental continuing education within a set time period as a disciplinary measure, which tells you continuing education exists in that program and is enforced.
Arizona recognizes out of state licensure through its universal recognition statute rather than through trade by trade reciprocity agreements. Section 32-4302 says that notwithstanding any other law, an occupational or professional license or certificate must be issued in the discipline applied for and at the same practice level to a person who establishes residence in Arizona, and without an examination to the spouse of an active duty service member accompanying a permanent change of station to an Arizona military installation, if a list of conditions is met. The person must currently hold a license or certification in at least one other state in the same discipline and at the same practice level, in good standing in every state where they hold one. They must have been licensed or certified by another state for at least one year. The other state must have had minimum education requirements, and work experience and clinical supervision requirements where applicable, and must verify that the person met them. The person must have previously passed any examination the other state required. They must not have had a license revoked, or surrendered one while under investigation for unprofessional conduct, and must not carry discipline from another regulating entity unless the cause was corrected and resolved. Note the trigger: establishing residence in Arizona. A company that stays based in Nevada or California and crosses the line to install does not get there through section 32-4302, and still faces the examination and experience route in section 32-1122.

Contracting without a license in Arizona is a crime, not a paperwork problem. Section 32-1164 makes acting in the capacity of a contractor without a license a class 1 misdemeanor. For a first offense the contractor shall be fined not less than $1,000, and for a second or any subsequent offense not less than $2,000. If the court imposes probation it must order the person to pay in full all state transaction privilege or use tax, all county transaction privilege or use tax, and all municipal transaction privilege or use tax arising from the acts constituting the offense. Section 32-1151 supplies the evidence rule that makes these cases straightforward: a permit from a government agency, or the employment of a person on a construction project, is prima facie evidence that a contract exists. A conviction also blocks licensure, because section 32-1122 bars a person convicted of contracting without a license from obtaining one for one year after the last conviction. The pesticide program carries its own prohibitions. Section 3-3624 makes it unlawful to engage in the business of pest management, commence work on a contract, or sign, issue or deliver any document expressing an opinion about pest management without a business license, to operate in a category without a qualifying party registered in that category, or to apply pesticides without being a certified applicator in that category or working under the direct supervision of one. Section 3-3613 adds graduated civil penalties for exempt landscapers who skip treatment records.
Arizona wrote a landscaper specific rule into its pest management chapter, and it is the single most misread requirement in the trade. Section 3-3613 exempts a person who conducts lawn, garden, shrub or tree maintenance and who applies herbicides for weed management. Then it takes the exemption back in eight situations. Licensure and registration apply if the person uses herbicides labeled restricted use or danger, uses sterilants or preemergent herbicides, offers weed management as the primary service or advertises weed management services, uses application equipment collectively holding more than five gallons of total mixed liquid herbicide at one address or project on the same day, uses more than twenty-five pounds of nonliquid herbicide at one address or project on the same day, uses or is part of a crew of two or more herbicide applicators at one address or project on the same day, applies an herbicide at a school or child care facility, or applies an herbicide at an address without performing maintenance there the same day. Advertising weed management is enough on its own. Pre emergent is enough on its own. Section 3-3601 defines pest management to include weeds in ornamental shrubs and trees, in lawns and along rights of way. Section 3-3614 lists ornamental and turf pest management as a certification category, and section 3-3616 bars doing business in a category without a qualifying party registered in that category. Even inside the exemption the paperwork continues. Section 3-3613 requires the exempt landscaper to give treatment records to each customer and to retain the same information for at least six months, showing the address, the date, the trade or common name of the herbicide, the amount applied, and the name of the person who applied it. Skipping those records draws a written notice of correction for a first violation, a civil penalty of at least fifty dollars for a second, and a civil penalty of not more than one thousand dollars for a third or later one. Section 3-3617 adds that each branch office of a licensed business must be registered before it opens and supervised by a registered branch supervisor, so a second yard is a separate registration.

Irrigation installation is where a landscaping contractor collides with drinking water rules, and those are enforced locally. The City of Phoenix technical guideline on backflow tester requirements cites the 2024 Uniform Plumbing Code sections 602 and 603, International Plumbing Code section 608, Phoenix City Code section 37-143 and Arizona rule R18-4-215. It requires every backflow prevention assembly in a potable water supply to be tested at installation, at repair or relocation, and at least annually after that, or more often when the authority having jurisdiction requires it, with testing and repairs performed by a certified backflow assembly tester on the city list. Arizona rule R18-4-215 is cited for the point that an assembly may not be placed in service unless it has been tested and is functioning as designed. The tester and the testing company must file tester competency certification, an annual test gauge calibration report, an Arizona state contractor license, and a City of Phoenix privilege license. The guideline states that a contractor license is not required if the company will only test assemblies and will do no work requiring a permit. No gauge may be used unless it passed calibration within the previous twelve months. The tester must send the original report to Phoenix cross connection control within ten days of each test, and the customer retains records for at least three years. Penalties for incomplete or inaccurate reports run from a written warning after at least ten verified incidents in one year to a three month and then a six month suspension from the recognized tester list.

Designing and installing are regulated by two different agencies in Arizona, and the word on your sign decides which one applies. Section 32-101 defines a landscape architect as a person qualified to engage in the practice of landscape architecture as attested by registration, and defines landscape architectural practice as professional services such as consultation, investigation, reconnaissance, research, planning, design or responsible supervision in connection with the development of land and incidental water areas, where the dominant purpose is the preservation, enhancement or determination of proper land uses, natural land features, ground cover and planting, aesthetic values, the settings of and approaches to buildings, natural drainage, and the inherent problems of the land relating to erosion, wear and tear, light or other hazards. The same section defines board as the state board of technical registration. Section 32-122.01 requires an applicant for professional registration as a landscape architect to be actively engaged in education or experience, or both, in the profession for at least eight years, and to pass the applicable in training and professional examinations unless exempt under section 32-126. Each year completed in a board approved landscape architectural school counts as one year, up to a maximum of five. Section 32-145 makes it a class 2 misdemeanor to practice, offer to practice, or by implication hold yourself out as qualified to practice a board regulated profession without registration, to advertise or display any card or sign indicating registration, or to use the word registered in conjunction with it. Section 32-141 adds that a firm offering those services must itself be registered.
Arizona is specific about where your license number has to appear, and the rule has a detail contractors miss. Under section 32-1124 the number on any license held by the licensee must be preceded by the acronym ROC, and must be posted or placed in a conspicuous place on premises where any work is being performed, on all written bids and estimates submitted by the licensee, on all published advertising, letterheads and other documents used to correspond with customers or potential customers, and on all broadcast, internet or billboard advertising. Internet and billboard advertising has one alternative: the ad may instead include a website address that links directly to a website prominently displaying the licensee name and license number. So a truck wrap or a paid search ad that carries only a domain works if the site itself shows ROC and the number prominently. A violation of the posting and placement rule is, at the discretion of the registrar, grounds for disciplinary action under section 32-1154, subsection A, paragraph 12, but it is not grounds for preventing the award of a contract, voiding an awarded contract, or any claim or defense against the licensee. A trade association directory listing distributed only to members is not advertising for this purpose. The flip side applies to unlicensed operators. Section 32-1121 withholds the casual or minor work exemption from anyone who advertises to the public without disclosing unlicensed status by including the words not a licensed contractor.
Sourcesazleg.gov 1azleg.gov 2
Verification is public, and a landscaping buyer in Arizona can do it before the first site visit. Section 32-1104 requires the registrar to maintain a complete indexed record of all applications and licenses issued, renewed, terminated, cancelled, revoked or suspended, including timely notation of any judicial disposition on appeal, for a period of not less than seven years. The registrar must also furnish a certified copy of any license issued, or an affidavit that no license exists, with a minimum charge of $10 for that service. That affidavit is the document a homeowner or an attorney uses to prove an operator was never licensed. The same section requires the registrar to publicly post a list of applicants for a contractor license on its website for at least twenty days, and limits what may appear in a licensee record on that website by barring any posting about the informal complaint process. The Registrar of Contractors runs a contractor search where anyone can look up a license by number or by business name. For a landscaping company, the practical move is to put the ROC number where buyers already are. Section 32-1124 requires it on bids and estimates anyway, so a bid that shows the number, and a website that shows the same number next to the business name, lets a buyer confirm the license in under a minute instead of taking your word for it.
These are common details other guides publish about Arizona, but we could not verify them from the agency source. Confirm them directly before relying on them.
Not for maintenance. Section 32-1121 exempts a person who functions as a gardener by performing lawn, garden, shrub and tree maintenance, so mowing, pruning and cleanup routes fall outside the contracting chapter. The exemption ends at installation. Grading, planting installations, hardscape and underground irrigation are contracting and need a Registrar of Contractors license.
The Arizona Registrar of Contractors, under Title 32, Chapter 10 of the Arizona Revised Statutes. Section 32-1151 makes it unlawful to act as, bid as, or purport to have the capacity of a contractor without a license in good standing unless an exemption applies. Cities issue permits and privilege licenses, not the trade license itself.
Section 32-1126 sets ceilings on a two year cycle. An original specialty residential license is capped at $350 and renewal at $270. Specialty commercial is capped at $1,000 and $900. Specialty dual licensed is capped at $1,350 and $1,170. Late renewal adds $50, and residential licensees also pay a recovery fund assessment of up to $600 per period.
Section 32-1152 brackets it by classification and volume. A specialty residential contractor posts not less than $1,000 and not more than $7,500. A specialty commercial contractor starts at not less than $2,500 and not more than $7,500 in the lowest volume bracket. Residential and dual licensees also post a $200,000 bond or join the recovery fund.
Four years of practical or management trade experience under section 32-1122, with at least two of those years inside the last ten, in the type of construction being licensed. Accredited college or manufacturer training may substitute, but never for more than two of the four years. A written examination taken within the prior two years is also required.
Irrigation installation is contracting, not maintenance. Section 42-5075 lists installing underground sprinkler or watering systems and building irrigation berms among landscaping activities, alongside grading and installing gravel or boulders, while repairing sprinkler or drip heads is treated as lawn maintenance. The classification you apply for with the registrar has to cover the installation work you sell.
Section 3-3613 exempts maintenance landscapers applying herbicides for weed management, then removes the exemption in eight cases. Restricted use or danger labels, sterilants or pre emergent herbicides, advertising weed management, more than five gallons of mixed liquid or twenty-five pounds of dry herbicide at one address in a day, crews of two or more applicators, schools and child care facilities all trigger licensing.
Section 3-3613 requires treatment records given to the customer and retained for at least six months. Each must show the address, the date, the trade or common name of the herbicide, the amount applied, and who performed the treatment. A first failure draws a written notice of correction, a second a civil penalty of at least fifty dollars, a third up to one thousand dollars.
Only if the state board of technical registration has registered you. Section 32-145 makes it a class 2 misdemeanor to practice, offer to practice, or hold yourself out as qualified in a board regulated profession without registration, or to advertise a card or sign indicating registration. Registration requires eight years of education or experience and passing examinations under section 32-122.01.
Section 32-1124 requires the number, preceded by the acronym ROC, in a conspicuous place on premises where work is performed, on all written bids and estimates, on all published advertising and letterheads, and on broadcast, internet and billboard advertising. Internet and billboard ads may instead link to a site prominently showing your name and number.
Section 32-1164 makes it a class 1 misdemeanor. A first offense carries a fine of not less than $1,000 and a second or later offense not less than $2,000, plus probation conditions requiring payment of state, county and municipal transaction privilege or use tax from the job. A conviction also blocks licensure for one year.
Through the Registrar of Contractors contractor search, by license number or business name. Section 32-1104 requires the registrar to keep an indexed record of licenses for at least seven years and to furnish a certified copy of a license, or an affidavit that no license exists, for a minimum charge of $10. Applicant lists are posted publicly for twenty days.
