Summary
In unincorporated Kern County's R-1 Low-Density Residential district, houses are capped at three stories or 35 feet, whichever binds first, and detached accessory buildings top out at two stories or 35 feet. Antennas, towers and chimneys get a taller allowance of 80 feet under Kern County Code section 19.18.080.
19.18.080 - Height limits. The following height limits apply in the R-1 district:
A. Buildings shall not exceed three (3) stories or thirty-five (35) feet. B. Detached accessory structures shall not exceed two (2) stories or thirty-five (35) feet. C. Radio and television antennas, communication towers, chimneys, and other similar structures shall not exceed eighty (80) feet.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 59 Update 1).
Full Breakdown
Kern County Code section 19.18.080 sets three separate height ceilings for the R-1 district: principal buildings cannot exceed three stories or 35 feet; detached accessory structures cannot exceed two stories or 35 feet; and radio and television antennas, communication towers, chimneys and similar structures cannot exceed 80 feet. These caps sit alongside the district's yard rules in section 19.18.070 and the minimum-distance-between-structures rule in section 19.18.090, which requires 10 feet between residential buildings and 6 feet between a residential building and an accessory building.
Section 19.08.150 closes an obvious loophole: a penthouse or roof structure built to house elevators, stairways, tanks, ventilating fans, towers, steeples or roof signs cannot be used to push a building over the district height limit, since the code states such structures 'shall not exceed the height limit provided in this title.' A second, geography-specific overlay appears at section 19.08.160: within the military flight areas mapped in Figure 19.08.160, tied to China Lake Naval Weapons Center and Edwards Air Force Base, no zone modification, zone variance or building permit may issue for a structure exceeding the mapped maximum height unless the responsible military authority gives the planning director written concurrence that the height creates no significant mission impact. If that concurrence is requested but not received within a reasonable time, the board of supervisors may still approve a height variance under the Chapter 19.106 variance procedure upon finding the benefits of the deviation outweigh the potential impact on military flight operations.
A lawfully built house that already exceeds today's R-1 height limit is treated as a nonconforming structure under section 19.108.020: it may continue and be repaired, but cannot be enlarged in area, space or volume, and if the planning director allows a limited expansion of a structure made nonconforming by a setback change, that approval is conditioned on there being 'no significant change in the existing height of the structure.'
Violations & Fines
A structure built over the 35-foot/three-story cap without an approved variance is a zoning code violation that the Kern County Planning and Community Development Department can require to be brought into conformance or removed; building permits will not issue for work that exceeds the limit. Property within the Figure 19.08.160 military overlay faces an added block: no permit issues at all without either military written concurrence or a board of supervisors variance finding that the height benefits outweigh flight-operation impacts. A planning director permit denial (including a height variance denial) can be appealed to the planning commission within 7 calendar days, and a planning commission decision can be further appealed to the board of supervisors under section 19.102.110.
