SB 1229 Arizona Senate · 57th Legislature - First Regular Session

planning; home design; restrictions; prohibition.

SB 1229 prohibits Arizona municipalities with over 70,000 residents from restricting home buyers' design choices or imposing certain development rules. It bans local requirements for shared amenities (like community pools), screening walls/fences, minimum lot sizes over 3,000 sq. ft. for new single-family homes, larger home size standards than other housing types, and excessive building setbacks (e.g., front setbacks over 10 feet, except for garages). The law directly affects home buyers, developers, and homeowners in qualifying cities by overriding local zoning and design regulations, while exempting building/fire codes, tribal land, and military zones. It applies only to new developments after the law’s effective date and does not affect existing housing or require municipalities to waive utility or safety standards.

MODERATE

The bill was reformatted from an introduced version to a senate engrossed version, with substantive changes to the text of the housing preemption law. The scope of applicability was expanded to include municipalities with populations over 70,000, and new provisions were added regarding utility requirements and garage setbacks. Several definitions were updated to clarify what counts as building codes and shared amenities.

Scope change

The bill now applies to developments in municipalities with populations exceeding 70,000 persons, whereas the original version did not specify a population threshold for applicability.

ELIGIBILITY

Added population threshold requirement of 70,000 persons for municipalities to be subject to the bill's provisions.

REQUIREMENT

New provision allowing municipalities to require electric and water utility plans and specifications for new single-family home developments.

New exception allowing minimum front setbacks of up to 18 feet for garage portions of homes facing the street.

Changed minimum lot size threshold from 1,500 square feet to 3,000 square feet for new developments of five acres or more.

Added restriction on lot coverage limits for single-family homes on lots less than 10,000 square feet.

DEFINITION

Expanded definition of building codes to include plumbing, mechanical, electric, residential construction, wildland urban interface, and energy conservation codes.
