We looked and could not find an official answer yet. Silence is not permission; ask El Segundo or Los Angeles County directly.

• Inspections — Building inspections inside El Segundo city limits
• Certificate of occupancy — Certificates of occupancy inside El Segundo city limits
• Minimum dwelling size — Minimum dwelling size for single-family homes in the R-1 zone inside El Segundo city limits
• Minimum lot size — Minimum lot size in the R-1 single-family zone inside El Segundo city limits

Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
