Bill Overview

Analyzed Economic Effects

3 provisions identified: 2 benefits, 1 costs, 0 mixed.

County service protection for surrounded residents

Annexation brings land inside a city or town's boundaries. A city can completely surround land that remains outside city limits only with a county service finding. The county board must find that annexation will not harm county service levels for residents in that remaining area.

Preapproved designs for homeowners and builders

Arizona cities and towns must provide preapproved housing plans in single-family zones where each housing type is allowed. Beginning July 1, 2026, they must offer at least three single-family plans and three accessory dwelling unit plans. Single-family plans must span 800–2,000 square feet or offer three sizes starting at the local minimum. Accessory dwelling units are smaller homes on the same property; their plans must offer 200, 600, and 1,000 square feet. Beginning January 1, 2027, at least three duplex plans and three triplex plans are required. Duplex and triplex units must be 400–1,000 square feet each. Each housing type must have at least three exterior design options. Anyone can submit plans, and cities must approve or deny them through administrative review, without discretionary decisions. Review fees cannot exceed those for plans of the same type and size. Cities must post approved plans and applicant contact details on their websites; posting does not mean city endorsement. Applicants must keep contact details current, and cities must remove plans within 30 days of an applicant's request. Programs can also use city-developed plans or plans preapproved by other Arizona cities or agencies.

Legal risk for preapproved plan users

Arizona cities and towns can attach legal conditions to using a preapproved housing plan. They can require users to release claims against the city, its employees, and its contractors and cover their legal liabilities. Each city decides whether to require this agreement; the law does not make it mandatory everywhere.
