Building Setbacks & Zoning in Irvine, CA: What Residents Actually Need to Know

If you live in Irvine or are thinking about moving there, building setbacks & zoning are one of those things you probably won't think about until they affect you directly. Irvine has 3 specific rules on the books covering different aspects of building setbacks & zoning, and some of them might surprise you.

Lot Coverage Limits

Irvine's Zoning Code sets maximum lot coverage by planning area and zoning district. Lot coverage includes all structures on the property.

Exceeding lot coverage: correction required. May need to remove impervious surface. Fines $200 to $1,000.

Pool equipment must be at least 2 feet from property lines and cannot exceed 48 inches in height. Specific setbacks vary by planning area, lot size, and building type. Variances require Planning Commission approval.
