At-a-glance

  • Licensing body: Arizona Registrar of Contractors (ROC)
  • License threshold: License required for any project over $1,000 or requiring a permit
  • Permit authority: City or county building department
  • Typical fees: $100–$500 for a window replacement permit

The $1,000 threshold

Any residential window project over $1,000, or any project requiring a permit, requires a licensed contractor in Arizona. Whole-home window projects always cross both thresholds.

The correct license category for window replacement is B or B-4 (Residential Contractor).

Slab conditions and acclimation

Phoenix-area sun is brutal on glazing seals and dark vinyl frames. Ask for a low-SHGC glass package and confirm the frame color is rated for desert exposure.
