Summary
Vista fixes front, side and rear yard minimums separately for each zoning district in Title 18 of its Municipal Code. In the R-1 Residence Zone, the city's standard single-family district, a house must sit at least 50 feet back from the street centerline, 10 feet from each side lot line, and 10 feet from the rear line.
In an R-1 zone, no building or structure shall be erected or maintained less than 50 feet from the centerline of the street upon which the building site fronts. ... Every lot and building site in an R-1 zone shall have a side yard on each side of the lot or building site, and each side yard shall be not less than ten feet in width, except that any such lot or building site occupied by a main building on February 1, 1974, may have a side yard of not less than seven and five-tenths feet on any side of such lot or building site not parallel to a public right-of-way or private street... Every lot and building site in an R-1 zone shall have a rear yard not less than ten feet in depth except in the following circumstance: A second story portion of any main building shall not be located closer than 20 feet from the rear property line in those cases where such rear property line adjoins any portion of the side yard property line of residential zoned property.
Full Breakdown

Both R-1 and E-1 buildings are separately capped at two stories or 35 feet, whichever is less.
Anyone unsure which zone applies to a parcel should confirm it on the city's zoning map before design begins, since a site plan drawn to the wrong zone's setbacks is rejected at plan check.
Violations & Fines
Violating any Title 18 setback standard is a misdemeanor under VMC Section 18.82.020, enforced by the City Manager's designee and the County Sheriff per Section 18.82.010. Each day a structure remains in violation counts as a separate offense under Section 18.82.030, and a building erected without the required setback or permit is declared a public nuisance per se under Section 18.82.040, letting the City Attorney sue for abatement or removal on the City Council's order.
