Castaic Schools: What to Know Before Move-In

Published by Michelle & Jon Dubner | Dubner Real Estate Group | Equity Union

If you are selling a home in Castaic this summer, Michelle and Jon Dubner want you to know one specific number: Castaic Union School District confirmed August 10, 2026 as the first day of school for the 2026-2027 year. For sellers, that date is not just a fact for your own family, it is a real deadline shaping how buyers relocating from Los Angeles and elsewhere are timing their Santa Clarita move right now.

Key Takeaways

• Castaic Union School District confirmed August 10, 2026 as the first day of school for the 2026-2027 year (source: castaicusd.com).
• Castaic High School, home of the Coyotes, serves the community at the high school level within the William S. Hart Union High School District.
• Relocating buyers work backward from the first day of school, so a home that can close with real time to spare before August 10 has a real edge with that audience.
• Sellers can use the confirmed school start date directly in listing conversations instead of a vague, unverifiable claim about schools.

The detail behind that sits in relocating to Santa Clarita.

Castaic Union School District has confirmed August 10, 2026 as the first day of school for the 2026-2027 year, according to the district's own calendar. That is an earlier start than many buyers relocating from outside California expect, and Jon and I make a point of sharing this exact date with both sellers and relocating buyers, because it changes how much runway a move actually has.

Castaic Union School District serves the community at the elementary and middle school level, and Castaic High School, home of the Coyotes, serves the community at the high school level as part of the William S. Hart Union High School District. Families relocating into Castaic should confirm the specific school for their address, since Castaic has grown enough in recent years that boundaries and capacity can shift.

If you are listing a home in Castaic, a portion of your real buyer pool is a family relocating from Los Angeles or elsewhere who wants to be moved in, unpacked, and enrolled before August 10. Jon and I tell Castaic sellers directly: knowing and naming that exact start date in conversations with your agent, and pricing and timing your listing with it in mind, is more useful than a generic "good school district" claim that does not tell a relocating family anything concrete.

Beyond the school calendar, Castaic offers something most of the rest of the Santa Clarita Valley does not: real space and a slower pace, anchored by Castaic Lake, a 2,235-acre reservoir open for boating, fishing, swimming, and camping. Williams Homes has built new-construction estates set among orchards, with 14 floor plans over $1 million, and next door, Hasley Estates offers larger acreage, much of it suited to horse property. Castaic sits at the junction of the I-5, which works well for commuters heading north toward the Central Valley or south toward Los Angeles, though that drive time is worth weighing against a specific work location before you commit to a street. The trade-off Jon and I are upfront about: there are fewer local dining and shopping options here than in Valencia, most errands mean a short drive, and Castaic is less walkable than some other Santa Clarita communities. Families relocating from a denser part of Los Angeles often see that trade-off as a genuine upgrade, more land and quiet for a lower price than Valencia, but it is worth knowing before you commit to a specific street.

Working backward from August 10, most relocating families need an accepted offer well before mid-July to have a realistic shot at closing, moving, and enrolling kids with any real breathing room. Jon and I build that backward timeline with every Castaic client we work with, whether you are selling to a relocating family or you are the one relocating, so the calendar works for you instead of against you.
