AZ SB1133

Amends prompt payment requirements for public contracts across multiple Arizona statutes, requiring payments within 14 days after certification and approval instead of current timelines.

Establishes that work estimates are automatically deemed approved after 7 days of submission unless the owner issues a specific written finding detailing unapproved items.

Requires contractors to pay subcontractors and material suppliers within 7 days after receiving progress payments, with interest accruing at 1 percent per month if payments are delayed more than 7 days.

Allows contractors to request interim payment for changed or additional work completed during the preceding calendar month based on actual costs incurred, with either party able to dispute the interim determination.

Extends prompt payment requirements to school districts, design professionals, and applies similar provisions to highway construction projects and other public construction contracts statewide.
