How do I check an Arizona contractor's license?

Arizona licenses contractors through the Arizona Registrar of Contractors (AZ ROC). Search at roc.az.gov → "Search a License." Enter the ROC license number or business name. AZ ROC issues licenses by classification — residential (KA, B, plus C-class specialty trades) and commercial (B-1, B-2, plus commercial C-class trades). Confirm Active status and that the license class covers your work. Arizona's system is one of the more rigorous in the country with active enforcement.

What is the difference between Arizona''s KA and B-1 licenses?

KA is the residential general contractor license — covers single-family residential construction and improvements. B-1 is the commercial general contractor license — covers commercial buildings. For senior aging-in-place projects, you want a KA-licensed contractor. A B-1 contractor cannot legally do residential remodeling unless they also hold the KA classification. Arizona also has B (Residential, light commercial up to two stories) and many specialty C-classes (C-37 plumbing, C-11 electrical, C-39 HVAC, etc.).

When does Arizona require a contractor license?

Arizona requires an AZ ROC license for any construction project where labor and materials exceed $1,000, OR where a permit is required (which often kicks in below $1,000 for plumbing, electrical, HVAC work). Below those thresholds, licensure is technically optional — but reputable contractors hold one anyway. For senior projects, hire ROC-licensed regardless of project size to preserve recourse and access to the Recovery Fund.

What is Arizona''s Residential Contractors Recovery Fund?

Arizona maintains a Residential Contractors Recovery Fund that pays homeowners up to $30,000 per claim against a licensed residential contractor who fails to perform, abandons the job, or causes damage. The Fund is one of the strongest senior consumer protections in the country. Funded by license fees, accessed through an administrative claim process (not lawsuits). Hiring an unlicensed contractor forfeits Recovery Fund access entirely.

What contractor scams target Arizona seniors?

Three patterns. (1) Post-monsoon and post-haboob (dust storm) roofers — Arizona's July-September monsoon season drives door-to-door roofer activity in senior neighborhoods, especially in Phoenix metro retirement areas (Sun City, Sun City West, Surprise, Mesa). (2) Post-wildfire contractors in Northern Arizona (Flagstaff area). (3) Driveway sealing and "free roof inspection" pitches targeting Sun City and other 55+ communities. Arizona AG Consumer Protection and AG Civil Rights Division pursue these with enhanced penalties under Arizona's elder fraud statutes.

How do I report a bad contractor in Arizona?

File a complaint with the AZ ROC at roc.az.gov → File a Complaint. AZ ROC can investigate, fine, suspend, or revoke the license, AND processes Residential Contractors Recovery Fund claims (up to $30,000 per claim). For consumer fraud generally: Arizona Attorney General Consumer Protection at azag.gov. Arizona elder-fraud statutes enhance penalties. The ROC complaint and Recovery Fund claim are free.

Does Arizona require contractors to be insured?

AZ ROC requires residential general (KA) contractors to maintain general liability insurance — typically $200,000-$500,000 depending on class. Specialty trade contractors have varying minimums. For senior projects over $10,000, request a current Certificate of Insurance showing $1 million GL and verify directly with the carrier. Workers compensation is required if the contractor has employees.

Arizona Contractor License Lookup (AZ ROC) 2026

The short version: Arizona licenses contractors through the AZ Registrar of Contractors (AZ ROC). Verify at roc.az.gov → Search a License. The classifications that matter for seniors: KA (residential general), B (residential light commercial), and specialty C-classes (C-37 plumbing, C-11 electrical, C-39 HVAC). Don’t confuse B (residential) with B-1 (commercial) — a B-1 cannot legally remodel your home. Arizona’s Residential Contractors Recovery Fund pays up to $30,000 per claim against licensed residential contractors — one of the strongest senior protections in the US. Phoenix retirement communities are heavily targeted; never hire post-monsoon door-to-door.

Arizona’s AZ ROC system + Recovery Fund

Arizona has a real, actively enforced statewide contractor license system through the AZ Registrar of Contractors. More importantly for seniors: Arizona maintains a Residential Contractors Recovery Fund that pays up to $30,000 per claim against licensed residential contractors who fail to perform, abandon jobs, or cause damage.³ That’s meaningful financial protection — equivalent to NYC’s DCWP Restitution Fund and stronger than most state bonds.

The catch: Recovery Fund eligibility requires the contractor to be currently licensed. Hiring unlicensed eliminates the entire protection.

This is the Arizona-specific companion to our national state contractor license lookup guide. For the master pre-hire workflow, see How to Find a Senior-Friendly Contractor.

How to verify: roc.az.gov

To verify: roc.az.gov → “Search a License.”¹ Enter ROC license number or business name.

Check:

Status Active (not expired, suspended, revoked)
Classification (KA / B / C-specific) covers your work
Business name matches the quote
Bond / insurance status active
Recovery Fund eligibility — confirm the contractor is Fund-eligible
Disciplinary history — recent ROC enforcement actions

Arizona’s classifications — the KA vs B-1 trap

This is where Arizona seniors most commonly get confused:²

Classification	Covers	Senior project fit
KA	Residential General (single-family)	Aging-in-place remodels
B	Residential Light Commercial (up to 2 stories)	Larger residential work
B-1	Commercial General	NOT residential — do not hire for home work
B-2	Commercial Specialty	Commercial only
C-37	Plumbing	Walk-in tub plumbing, fixture work
C-11	Electrical	Bedside circuits, GFCI
C-39	HVAC	Heat pump install
C-42	Roofing	Roof repair

A B-1 license cannot legally remodel your home — it’s commercial only. This is the most common Arizona mismatch we see seniors make. Always confirm the classification is residential (KA, B, or specific residential C-class) for residential work.

The Recovery Fund — Arizona’s strongest senior protection

Arizona’s Residential Contractors Recovery Fund pays homeowners up to $30,000 per claim against licensed residential contractors who:³

Fail to complete contracted work
Abandon the job
Cause damage through poor workmanship
Violate the contract or ROC rules

The claim process is administrative through the AZ ROC — no lawsuit required. Funded by contractor license fees, not taxpayer dollars. Only licensed residential contractors are Fund-eligible — hiring unlicensed forfeits the protection entirely.

For senior aging-in-place projects in the $5K-$30K range, the Fund is meaningful baseline financial protection. For larger projects above $30K, the Fund is partial protection — combine with the 3-quote method, the contract clauses checklist, and insurance verification.

Arizona senior scam patterns

Monsoon-season roofers — Arizona’s July-September monsoon season drives intense post-storm roofer activity. Phoenix metro retirement communities (Sun City, Sun City West, Surprise, Mesa, Apache Junction) see particularly heavy targeting.
Haboob (dust storm) damage pitches — door-to-door contractors after major dust events claim “we noticed your home’s exterior damage” with fabricated urgency.
Northern Arizona post-wildfire scams — Flagstaff, Sedona, Prescott area after major wildfires.
Driveway sealing and free roof inspection pitches — 55+ communities targeted aggressively spring through fall.
Arizona AG Consumer Protection + ROC enforcement — both pursue elder home-repair fraud aggressively. Arizona elder-fraud statutes enhance penalties.⁴

If something goes wrong

AZ ROC violations or unfinished work: file at roc.az.gov + apply to the Recovery Fund (up to $30K per claim).
Consumer fraud generally: Arizona AG Consumer Protection at azag.gov.
Elder financial abuse: also contact your county Adult Protective Services. Arizona elder-fraud statutes provide enhanced penalties.
