SECTION 1: Arizona ROC Laws, Rules & Business
Requirements
1. Under Arizona Revised Statutes, a B-3 General Carpentry contractor license is required for
any carpentry project where the total cost exceeds:
A) $500
B) $1,000
C) $2,500
D) $5,000
(Correct Answer: B) Rationale: Arizona law (A.R.S. § 32-1121) requires a contractor's license
for any project where the total cost of labor and materials exceeds $1,000. Work below this
threshold may be performed without a license, but any project over $1,000 requires appropriate
ROC licensing.
2. The Arizona Registrar of Contractors (ROC) primary purpose is to:
A) Set wage rates for construction workers
B) License, regulate, and discipline contractors to protect public health, safety, and
welfare
C) Collect sales tax from contractors on materials
D) Issue building permits for residential construction
(Correct Answer: B) Rationale: The Arizona ROC's mission is consumer protection — it
licenses contractors, investigates complaints, disciplines licensees for violations, and ensures
contractors maintain minimum competency standards. It does NOT issue building permits (that's
the local jurisdiction's responsibility).
,3. A B-3 licensee in Arizona must carry minimum general liability insurance of:
A) $100,000 per occurrence
B) $250,000 per occurrence
C) $500,000 per occurrence
D) $1,000,000 per occurrence
(Correct Answer: A) Rationale: Arizona ROC requires B-3 licensees to maintain minimum
general liability coverage of $100,000 per occurrence. Requirements vary by license class —
commercial licenses require higher minimums. Proof of insurance must be maintained
throughout the license term.
4. Under Arizona ROC rules, a contractor's license renewal must occur every:
A) 1 year
B) 2 years
C) 3 years
D) 5 years
(Correct Answer: B) Rationale: Arizona contractor licenses must be renewed every 2 years.
Failure to renew results in license expiration, and working on an expired license is a violation
that can result in civil penalties and consumer complaints.
5. A homeowner files a complaint with the Arizona ROC against a B-3 contractor. The ROC's
workmanship standards require the complaint to be filed within:
A) 1 year of substantial completion
B) 2 years of substantial completion
C) 3 years of substantial completion (for workmanship complaints on residential)
D) 5 years of substantial completion
(Correct Answer: B) Rationale: Arizona ROC workmanship complaints must generally be
filed within 2 years of discovery of the defect, but no more than 4 years after project completion
for most residential complaints. The specific timeframe depends on the nature of the defect.
6. Under Arizona law, which of the following actions by a B-3 contractor constitutes "unlawful
acts" subject to ROC discipline?
, A) Subcontracting work to another licensed contractor
B) Abandoning a contract without legal justification
C) Using materials that meet or exceed specification requirements
D) Providing a written contract for all work over $1,000
(Correct Answer: B) Rationale: A.R.S. § 32-1154 lists unlawful acts including: abandoning a
contract, failing to complete work, misrepresenting qualifications, falsifying records, and
performing work outside license scope. Abandonment without justification is one of the most
serious violations.
7. An Arizona B-3 contractor must provide a written contract for residential work when the
project exceeds:
A) $500
B) $1,000
C) $2,500
D) $5,000
(Correct Answer: B) Rationale: Arizona requires written contracts for residential projects over
$1,000 — the contract must include the contractor's license number, scope of work, contract
price, and payment schedule. Verbal contracts for large projects expose both parties to
significant risk.
8. Under Arizona lien law, a contractor who has not been paid must file a mechanic's lien within:
A) 30 days of completing work
B) 60 days of completing work
C) 90 days after completion or last day of work
D) 120 days after completion
(Correct Answer: C) Rationale: Arizona's mechanic's lien statute (A.R.S. § 33-993) requires
contractors to file a lien within 90 days of completing work or the last day work was performed.
A preliminary 20-day notice is also required to preserve lien rights on private projects.
9. The "Preliminary 20-Day Notice" required in Arizona is used to:
A) Give the homeowner notice before starting work
B) Preserve the contractor's right to file a mechanic's lien — must be served within 20
days of first furnishing labor or materials
C) Notify the ROC of a new project
, D) Inform subcontractors of payment terms
(Correct Answer: B) Rationale: Arizona's preliminary notice (A.R.S. § 33-992.01) must be
served on the property owner, general contractor, and construction lender within 20 days of first
furnishing labor or materials — failure to serve this notice eliminates lien rights for work
performed before the notice.
10. A B-3 contractor in Arizona who performs work outside their licensed scope:
A) Is allowed if the work is closely related to carpentry
B) May face ROC disciplinary action, fines, and potential license suspension
C) Only needs to notify the ROC within 30 days
D) Is exempt if the total cost is under $5,000
(Correct Answer: B) Rationale: Performing work outside the licensed scope violates A.R.S. §
32-1154 — it exposes the contractor to ROC discipline (fines, probation, suspension,
revocation), civil liability, and potential criminal prosecution. The B-3 license scope is
specifically limited to general carpentry.
SECTION 2: Blueprints, Plans Reading & Specifications
11. On a set of architectural drawings, the abbreviation "TYP" means:
A) Top yard plate
B) Typical — the detail shown applies to all similar conditions throughout the drawings
C) Type of panel
D) Template yard plan
(Correct Answer: B) Rationale: "TYP" (Typical) indicates that a detail, dimension, or
specification applies in all similar locations throughout the project — not just at the specific
location shown. It reduces drawing clutter by avoiding repetition of the same detail.
12. A "section view" on architectural drawings shows:
A) The exterior elevation of a building
B) A cut-through view of the building or component, as if sliced at the cutting plane
location to reveal interior construction
C) The foundation plan from above
D) The roof plan from above
