Overview

• The City Council approved caps of four to six ADUs per single-family parcel based on lot size following a 5-4 vote on June 16
• Reforms impose two-story height limits, parking requirements for units outside transit zones, increased setbacks from property lines and a community enhancement fee
• Nearly 200 residents spoke at City Hall to protest the previous unlimited ADU incentive and warn of neighborhood character impacts
• State officials cautioned that stricter ADU rules could jeopardize San Diego’s pro-housing status and compliance with state law, prompting adjustments to some requirements
• The policy changes must pass a second reading and receive mayoral approval before taking effect, potentially in August 2025
