Summary
Chula Vista's R-1 zone sets front, side, and rear setbacks by lot classification in a table at CVMC 19.24.070, but CVMC 19.24.100 overrides it with a hard floor: dwelling units must sit at least three feet from any side property line (five feet in R-1-5) and 10 feet apart.
Front and side yard setback requirements for particular zone classifications shall be provided and maintained in accordance with the schedule set forth hereinabove, or in accordance with those specified in the building line map. Those setback requirements as shown on the adopted building line map of the City shall be adhered to in any case where said requirements differ from setbacks established in said schedule. Furthermore, regardless of any minimum side yard requirements as indicated in said schedule, the minimum distance between dwelling units shall be 10 feet, and no dwelling unit may be constructed closer than three feet to any side property line with the exception of the R-1-5 zone classification which shall maintain a minimum of five feet. Said minimum three-foot dimension shall be measured on a horizontal plane on the level of the foundation of the dwelling unit.

Chula Vista's single-family setbacks run through two linked sections. minimum) get a 25-foot front, 10-foot exterior side yard, 10-foot one-side yard, 20-foot combined side yards, and 20-foot rear yard; R-1-10 lots get 20 feet front with the same side/rear figures; R-1-7 lots (the city's 'basic or standard lot size') get 15-foot front, 10-foot exterior side, 10-foot side, 13-foot combined sides, and 20-foot rear; and the smallest R-1-5 lots get 15-foot front, 10-foot exterior side, 5-foot one side, 10-foot combined sides, and 15-foot rear. 100 then adds the rule that actually controls on the ground: those table setbacks apply 'or in accordance with those specified in the building line map,' and wherever the city's adopted building line map differs from the schedule, the building line map controls.
100 imposes an absolute floor 'regardless of any minimum side yard requirements' in the table: the minimum distance between dwelling units must be 10 feet, and 'no dwelling unit may be constructed closer than three feet to any side property line,' except in the R-1-5 zone, which requires a minimum of five feet. That three-foot dimension is measured 'on a horizontal plane on the level of the foundation of the dwelling unit,' so it applies at the foundation line, not just the wall above it.
