Porter Ranch is ZIP 91326 inside the City of Los Angeles, sitting on the north hillside of the San Fernando Valley. I'm Brian Cooper, REALTOR at eXp Realty (DRE# 01434286), and this page is the ZIP-level market overview I refer clients to before they start touring. The headline numbers, segment breakdown across older tracts and new construction, what's moving the market in May 2026, and the data sources I use so the numbers can be checked.
What ZIP 91326 covers
ZIP code 91326 is the City of Los Angeles postal code that includes Porter Ranch and adjacent residential areas on the north hillside of the San Fernando Valley. The boundary lines follow the Aliso Canyon area to the north, the 118 Reagan Freeway to the south on parts of the south boundary, and connect with adjacent Granada Hills (91344) and Chatsworth (91311) ZIPs.
Within 91326 you find the original Pacific Enterprises era master plan (1970s-2000s), the late-90s/early-2000s Bellagio gated community, the various 1980s-1990s tracts, and the active Toll Brothers hillside collections built out across the 2010s-2020s.

Active single-family inventory across 91326 is roughly 80-110 listings month-to-month, with a meaningful share concentrated in the Toll new-construction collections (active phases plus resaling earlier phases).

Segment breakdown
The 91326 market is best understood by segment rather than a single median. The older Porter Ranch Estates and adjacent 1970s-1990s tracts run $1.1M-$1.8M. Bellagio (gated) runs $1.8M-$2.8M. Toll Bella Vista, Hillcrest, and resale phases of Westcliffe run $1.6M-$2.6M. Renaissance and Ridge Collection (newest, upper-hillside) run $2.0M-$3.0M+.
When pulling comps for a specific property, pull within the same segment. Mixing across segments produces noisy comp data because the underlying value drivers (lot size, Mello-Roos, HOA, architecture era) differ substantially.
What's driving the May 2026 market
Granada Hills Charter High School continues to anchor demand across Porter Ranch tracts — buyers prioritize the school assignment, and 91326 addresses routing to GHC carry a meaningful premium versus equivalent product in nearby ZIPs not feeding GHC.
Toll's active phases continue to draw new-construction buyers who would otherwise have shopped resale. The Aliso Canyon disclosure remains a real-but-manageable diligence item — buyers who do the disclosure work proceed; buyers who don't sometimes pause and route to alternative ZIPs (Chatsworth, Granada Hills, Northridge).
Mortgage rates and Mello-Roos structure together drive the all-in monthly cost analysis for most buyers. The CFD impact alone shifts effective monthly cost by $300-$500/month on Toll new construction.
How Porter Ranch compares to adjacent ZIPs
ZIP 91326 (Porter Ranch) typically prices above ZIP 91311 (Chatsworth) and ZIP 91344 (Granada Hills) on a per-square-foot basis. The premium reflects the master-planned community structure, the Toll new construction available within 91326, and the school assignment to Granada Hills Charter HS for most parcels.
Buyers price-sensitive but wanting GHC school assignment sometimes shop Granada Hills (91344) for parcels that route to GHC — those are the cross-ZIP comps to pull when checking value.
