Compton, CA Building Setbacks & Zoning: Setback Rules (2026)

Compton's Low-Density (R-L), Residential Agriculture (R-A) and Medium-Density (R-M) zones all carry the same base yard numbers: a 20-foot front yard, a 3-foot interior side yard, a 5-foot street side yard (5 feet on any side for two-or-more-story buildings), and a 20-foot rear yard. The High-Density Residential Zone (R-H) trims those to a 15-foot front yard and a 10-foot rear yard, though it still keeps the 3-foot interior and 5-foot street side yard standard. 3(f)(3)(b) gives shallow lots relief: a parcel 90 feet deep or less can reduce its rear yard to 20% of the lot's depth, but never below 10 feet, and a detached one-story accessory structure or unenclosed patio cover may occupy up to half of the required rear yard.

General exceptions in Sec. 3 let architectural features like eaves, cornices and fire escapes protrude a few feet into required yards, and uncovered porches or platforms can extend up to 6 feet into a front or rear yard. A separate rule in the same section caps paving of any required front or street side yard at 25% of its area, aside from driveway access. Every setback is measured against the plans the Building and Planning Department reviews at permit stage, and any building erected closer than these minimums needs a variance from the Planning Commission before construction can proceed.
