City Attorney Rosen told the Arroyo Grande City Council that a string of state laws—ministerial approvals, density bonus rules, and builder's remedy—reduce local discretion and place tight deadlines and vesting rules on local reviews, complicating the city's forthcoming RHNA housing-element work.

Council introduced ordinances to update local SB 9 (urban lot splits/two‑unit development) and accessory dwelling unit rules to reflect recent state bills (SB 450, AB 1061, SB 543, AB 462, AB 1154). Changes narrow historic-resource exclusions, adjust unit-count rules, and add statutorily required ADU categories and timelines.
