Castlebay Lane in the Porter Ranch school feed

Castlebay Lane is one of LAUSD's elementary schools serving Porter Ranch parcels at the K-5 level. Many Porter Ranch homes feed Castlebay Lane for elementary, Frost Middle for grades 6-8, and Granada Hills Charter High School for grades 9-12. This is the most common Porter Ranch school feed pattern.

Specific attendance is address-driven. Some Porter Ranch perimeter parcels route to other LAUSD elementary schools — verify the specific address with LAUSD School Finder rather than relying on general assumptions.

How attendance boundaries work in LAUSD

LAUSD attendance boundaries are address-specific. The district maintains a School Finder tool that accepts a street address and returns the assigned schools for that address. Use this tool before relying on any specific school assignment in a purchase decision.

LAUSD boundaries have shifted historically and can change. Resale listings sometimes carry outdated school assignment information. Don't take the listing word for it — pull the assignment yourself via School Finder.

Verifying assignment for a specific Porter Ranch parcel

Run this check on every Porter Ranch home you're seriously considering, before you write the offer.

  • Go to the LAUSD School Finder tool
  • Enter the exact street address of the property
  • Note the assigned elementary, middle, and high school
  • Screenshot the result and date it
  • Cross-reference with the school's own attendance information page
  • Confirm with the school directly during open enrollment season if needed

Charter status and intra-district transfer

Some LAUSD elementary schools operate as affiliated charter schools, which can affect enrollment process and program offerings. Verify current charter status of Castlebay Lane and any other Porter Ranch schools directly with LAUSD and the school itself.

LAUSD also operates intra-district transfer processes for certain schools — students assigned to one school can sometimes transfer to another via specific application processes. Eligibility and process vary year to year. Check with LAUSD's enrollment office for current procedures.

What buyers commonly ask

Parents shopping in Porter Ranch routinely ask whether a specific home 'feeds Castlebay Lane.' The answer requires checking the actual address — there's no shortcut. ZIP-level or tract-level generalizations are useful starting points but inadequate for the final assignment.

Buyers should also verify middle school (Frost Middle is common for Porter Ranch) and high school (Granada Hills Charter HS is common for Porter Ranch). Each assignment is independent — verify all three for the specific address.

Why school assignment moves Porter Ranch pricing

School assignment is one of the largest factors in Porter Ranch resale pricing. Parcels routing to highly-rated schools command premiums versus equivalent product routing elsewhere. Granada Hills Charter HS in particular is a major value driver across Porter Ranch.

When pulling comps for a Porter Ranch home, factor school assignment. A parcel routing to GHC versus a perimeter parcel routing to another high school may trade in different bands even within 91326.
