Oakland Planning Code Title 17 caps single-family home size through floor-area ratio, lot coverage, and height limits, with neighborhood-specific design review in the Oakland Hills, Rockridge, and Crocker Highlands aimed at preserving streetscape character and reducing oversized teardown rebuilds.
Oakland Planning Code Title 17, adopted as a form-based code in 2011, restricts single-family mansionization through bulk controls, including maximum floor-area ratio, lot coverage caps, and zone-specific height limits. Hillside zones layer additional setback, story-stepping, and view-corridor rules. Significant tear-down rebuilds typically trigger design review, neighbor notification, and sometimes hearings before the Planning Commission. State density bonuses and ADU laws partially override the bulk controls, but baseline single-family limits remain enforceable. CEQA review applies in some hillside and historic contexts even for single-family projects.
Exceeding bulk envelopes without approved variances triggers stop-work orders, redesign and removal of nonconforming portions, and substantial fines, plus potential CEQA challenges by neighbors in sensitive zones.
