R-1 — Residential
Front: 15 feet minimum, but the contextual rule controls on built-out blocks. Where 50 percent or more of the block frontage is built, the front setback must fall within 5 feet, plus or minus, of the average setback of the five adjacent lots in each direction, dropping the greatest and least values (Section 2.06 footnote D). The average controls in both directions, so on some blocks the required setback is below 15 feet.
Sides: 5 feet each. Rear: 30 feet for a one-unit dwelling, 20 feet for two- to four-unit and multiple-unit dwellings (Section 2.06).
