Full Breakdown
20-2 sets the 'Minimum Yard Setbacks' for the R-1A, R-1B and R-1C one-family zoning districts. All three districts share a 20-foot first-story front setback, a 10-foot first-story street-side setback and a 5-foot first-story interior-side setback. Second stories must step back an additional 5 feet from the first-story line on the front, street-side and interior-side yards in R-1A and R-1B; R-1C caps out at 1½ stories, so its table lists 'N/A' for the second-story rows. Rear setbacks diverge the most by district: R-1A requires 10 feet, R-1B requires 20 feet, and R-1C requires 20 feet on parcels less than 100 feet deep but 35 feet on every other parcel.
A: distances run horizontally to the closest support wall of the structure, not along the topography of the lot, and a required setback only needs to meet the minimum distance in the title regardless of how the existing structure was originally built. 20-2 also sets a swimming pool setback separate from the main structure lines: a minimum 10-foot side-yard setback and a 50-foot front-yard setback, or placement within the rear 50 percent of the lot depth, whichever is less. 050.
Violations & Fines
Setback violations are caught at plan check, not fined after the fact in the zoning code itself. Section 17.10.020.D prohibits erecting, moving, altering, enlarging or rebuilding any building or structure, or encroaching on the open space around one, except in conformity with the yard regulations for its zoning district, so plans intruding into the 20-foot front, 10-foot street-side, 5-foot interior-side or district rear setback are returned unapproved. Structures already built into a setback are treated as nonconforming under the same section.
