Tehachapi is an incorporated city in Kern County. Projects here follow Tehachapi's own zoning and building rules on top of the county-level environmental rules that apply across Kern County. The county rules most likely to catch a project applicant off guard are listed below.
These Kern County rules apply to projects in Tehachapi, on top of any city-specific Tehachapi requirements.
The county straddles two separate air quality management districts; which one governs your project depends entirely on location relative to the Tehachapi Mountains — and the standards differ in ways that affect mitigation requirements and thresholds.
Kern is California's largest oil-producing county, and decades of extraction mean projects across the valley floor may encounter contaminated soils, active well infrastructure, or underground pipelines that require investigation before grading begins.
Portions of the county are covered by regional habitat conservation plans that charge mitigation fees for new development — which plan applies and what it costs depends on project location, so check coverage before finalizing your budget.
Agricultural land under a Williamson Act contract can't easily be converted for other uses — a constraint that applies across both the valley floor and the foothill areas where residential and energy projects often expand.
