This bill prohibits cities, counties, and state agencies from creating or enforcing any urban growth boundaries that restrict new development, housing options, or public services outside designated areas. It declares such boundaries void in local ordinances, rules, or state contracts, citing Arizona voters' 1998 and 2000 rejections of similar policies. The law aims to prevent policies that could reduce housing affordability by limiting land availability for development, referencing studies from other states. It requires a three-fourths legislative vote to take effect.
SB 1529 requires new residential building permit applicants in Arizona's active water management areas to obtain either a "certificate of assured water supply" from the state water department or a written commitment from a designated water provider (city, town, or private company), plus pay specific water fees. It applies to all new residential dwelling units (including mobile homes used as primary residences) but exempts projects with zoning approvals or applications submitted by September 30, 2026. The bill ties permit approval directly to verified water availability, ensuring developers demonstrate access to a reliable water source before construction begins. This affects developers, homebuilders, and homeowners seeking permits for new residential properties in designated water management zones.
This bill requires Arizona municipalities with over 75,000 residents to allow accessory dwelling units (ADUs) - small rental homes on single-family lots - as permitted uses, without requiring additional parking, design matching, or restrictive covenants. It mandates that all lots zoned for single-family homes must permit at least one attached and one detached ADU, with size limits (max 75% of main home or 1,000 sq. ft.). Municipalities may only require fire sprinklers in ADUs if they already had residential sprinkler ordinances before December 2009; otherwise, they cannot impose such requirements. Failure to adopt compliant regulations by January 1, 2025, would automatically allow ADUs without restrictions on all residential lots. The bill directly affects homeowners seeking to add ADUs and local governments managing zoning rules.
HB 2077 requires developers to prove water supply availability before obtaining building permits for multifamily housing in the Prescott Active Management Area. Specifically, it mandates that applicants provide either a written water service commitment from a designated water provider or a Department of Water Resources certificate with their permit application. This applies to new projects and excludes developments that already secured zoning approval before the bill took effect. The law directly affects multifamily residential developers in Prescott AMA, ensuring water supply planning aligns with local infrastructure capacity.
