SB 1051 expands exemptions for non-licensed individuals to design certain commercial space alterations in Arizona. It allows non-registered engineers to make interior nonstructural changes to commercial units under 3,000 square feet and single storage additions under 1,500 square feet without requiring a licensed engineer's approval. The bill specifically targets small-scale, low-risk modifications to reduce regulatory hurdles for property owners and small businesses. These changes apply only to projects meeting the defined size limits and not involving structural elements like bearing walls.

MINOR
The bill was formally enacted into law after being approved by the Governor and filed with the Secretary of State. A significant substantive change was made to the definition of 'commercial space' alterations, adding an exception that now excludes assembly occupancy areas from the size limit. Minor formatting and capitalization adjustments were also made throughout the text.
Scope change
The bill's scope was narrowed regarding interior alterations; the previous rule allowing nonstructural changes to units under 3,000 square feet now explicitly excludes assembly occupancy spaces, meaning those specific areas are no longer covered by this simplified alteration provision.
REQUIREMENT
Added an exception to the 3,000 square foot limit for interior nonstructural alterations, specifically excluding assembly occupancy areas as defined by the building code.
TIMELINE
Added official dates indicating the bill was approved by the Governor and filed with the Secretary of State on May 12, 2025.
TECHNICAL
Corrected capitalization errors in the title and section headers, changing 'Senate Engrossed' to 'House Engrossed' and standardizing the bill number display.
