About
Life in Castaic
Living here means accepting that you're in a commuter corridor—tens of thousands of people drive through Castaic daily on I-5 heading to or from Los Angeles, and if you work in the city, you're joining them most days with an average commute of about 31 minutes. The trade-off for that commute is a median household income of $129,863 and a median home value around $792,000, which is genuinely affordable compared to much of Los Angeles County, though still a significant investment. Summers here are legitimately hot, regularly hitting the 90s and pushing past 100°F from June through September, while winters are cool and moderately rainy, which means you're trading Southern California's beach lifestyle for inland heat and dryness.
