Ventura, CA Building Setbacks & Zoning: Structure Height Limits (2026)

Community Development measures height under Section 24.405.040: from the average established curb grade at the front lot line to the highest point of the structure, with separate rules for sloping lots, through lots, and the R-1-B/R-2-B beach zones. Section 24.405.030 lets chimneys, ham radio antennas, residential radio/TV antennas, and elevator or stairway roof housing extend above the 30-foot cap. In the hillside area defined in Chapter 24.110, Section 24.405.050 replaces the flat 30-foot rule for R-1, R-2, and R-3 lots: where the rear lot line sits higher and the slope is 10 percent or less, height is capped at 12.5 feet above the rear lot line, 15 feet above the rear setback line, or 30 feet at the building's corner points, whichever is lowest; where slope exceeds 10 percent, the rear lot line figure drops to 10 feet.

Applicants in the hillside area must submit topographic and lot-survey information from a licensed architect, surveyor, or civil engineer, plotting five elevation reference points, unless the director waives that requirement under Section 24.405.050(C). Section 24.210.070(E) also limits any story below a half-story to a 22-foot ceiling or roof height above average natural grade. A property owner who wants to exceed these limits must apply for a variance under Chapter 24.535, submitting site and elevation plans, height and elevation data for the proposed and existing structures on the site and abutting lots, and sight-line drawings showing effects on public views.
