Tucson's Unified Development Code allows density bonuses and development incentives for projects that include affordable housing, supportive housing, or transit-supportive design, layered with state law incentives for accessory dwelling units.
Under UDC incentive provisions and adopted infill housing tools, projects providing income-restricted units can request increased density, reduced parking, or modified setbacks subject to ministerial or rezoning review depending on scale. Tucson has also adopted streamlined processes for accessory dwelling units (ADUs) consistent with state housing legislation, and pursues missing-middle housing reforms tied to Plan Tucson's housing targets. The city coordinates with the Pima County Industrial Development Authority and Low-Income Housing Tax Credit projects for layered financing.
Failure to maintain affordability covenants results in repayment of bonus value, recorded covenant enforcement, and possible code-enforcement action requiring restoration of covenant compliance.
