Full Breakdown
Under Planning Code Section 132.1, upper floors of buildings facing a public sidewalk in any C-3 downtown district may be required to step back to preserve the openness of the street to the sky and maintain a continuous street wall. The maximum setback depth is set by a table keyed to street width and street-wall height, capped at 24 feet where the street is 76 to 80 feet wide and the wall is 68 feet or less. Market Street frontages between Powell and Tenth Streets face a flat 25-foot setback at 90 feet in height. The Planning Department administers these rules through the large-project authorization process under Section 309.
Violations & Fines
Development approvals in C-3 districts are conditioned on compliance; the Planning Commission reviews streetwall and setback compliance under Section 309 large-project procedures before permits issue.
