The Influence Of Accessory Dwelling Unit Policy On The Contributing Factors To ADU Development

SCAG and California State Polytechnic University, Pomona’s Urban Planning Department collaboratively published a peer-reviewed paper in the renowned Journal of Housing and the Built Environment highlighting the Accessory Dwelling Unit (ADU) Potential project. The paper investigates the impact of Los Angeles’ ADU ordinance on property and neighborhood characteristics in relation to ADU development. Multilevel, logistic, regression models reveal that the ordinance has diversified the types and locations of ADU construction, which ultimately reduces the influence of pre-existing property characteristics. The paper suggests that the ordinance likely attracted ADU development in areas with better bus transit accessibility. These findings offer valuable insights for jurisdictions seeking to create effective policies to support ADU development.
