Full Breakdown
030 governs how building height is measured citywide: the vertical distance from the average elevation of finished grade to the highest point of the structure, specifically excluding chimneys, antennas, elevator equipment, and similar mechanical appurtenances from the count. 010-1A (Development Standards for Residential Zones), which sets primary building height at 35 feet in the Very Low (VL), Very Low Estate Home 14000 (VL-EH 14000), Low (L), Low-Etiwanda Specific Plan (L-ESP), Low Medium (LM), Low Medium-Terra Vista (LM-TV), and Low Medium-Etiwanda Specific Plan (LM-ESP) zones. Only the Very Low Estate Home 9000 (VL-EH 9000) subzone gets an extra foot, capping at 36 feet, while the LM-ESP South subzone carries no listed maximum in the table.
010-1B extends the same structure into the higher-density Medium, Medium High, and High zones, where heights climb to 40, 45, 55, and 65 feet depending on subzone, some of them footnoted for additional design review. 030-2 illustrates how that exemption is measured. 110, which allows the planning director to approve up to a 10 percent increase in maximum height after finding the request compatible with the surrounding neighborhood.
Violations & Fines
Building height is checked by the building and safety division at plan check and again at framing inspection, since a structure that exceeds the Table 17.36.010-1A maximum cannot receive a final inspection or certificate of occupancy. An owner who builds over height without first obtaining a minor exception under Section 17.16.110 faces the citywide penalty in Section 1.12.010(D): a misdemeanor punishable by up to a $1,000 fine, six months in jail, or both, with continued noncompliance treated as a separate daily offense until the structure is brought into conformance or removed.
