Crafting the Next Generation of ADU Incentives

About the ADU Bonus Program

The City of San Diego has implemented an Accessory Dwelling Unit (ADU) Bonus Program that offers increased density for Affordable ADUs. This incentive has led to the construction of naturally affordable deed-restricted ADUs throughout the city.
