Porter Ranch (ZIP 91326) and Granada Hills (ZIP 91344) sit adjacent on the north hillside of the San Fernando Valley, and many buyers cross-shop them. I'm Brian Cooper at eXp Realty (DRE# 01434286), and this is the side-by-side I share with buyers weighing the two. The shared school anchor (Granada Hills Charter HS), the pricing differential, the Mello-Roos picture, and the practical differences in what your money buys in each.
Geography and ZIP boundaries
Porter Ranch (ZIP 91326) sits on the upper hillside of the north San Fernando Valley. Granada Hills (ZIP 91344) sits immediately east and southeast, extending from the same hillside down into the flats. The ZIPs share a long border along Balboa Boulevard, Rinaldi Street, and Devonshire Street depending on the section.
Both are City of Los Angeles neighborhoods, served by LAUSD schools, LA City services, and routed through the 118 Reagan Freeway as the primary east-west corridor.
Pricing comparison
Median single-family residential sale price in 91326 is approximately $1.25M; in 91344 approximately $1.10M as of May 2026. On a per-square-foot basis, Porter Ranch typically trades at a small premium — reflecting the master-planned structure, Toll new construction available within 91326, and slightly larger lot sizes on some tracts.
Granada Hills inventory skews to older tract product (1960s-1990s primarily) with no or minimal Mello-Roos. The lower median reflects the older housing stock and the absence of contemporary new construction comparable to Toll Porter Ranch.
| Metric | Porter Ranch (91326) | Granada Hills (91344) |
|---|---|---|
| Median sale price (May 2026) | ~$1.25M | ~$1.10M |
| Median DOM | ~23 days | ~21 days |
| Toll new construction available | Yes (Renaissance, Skyline, etc.) | Limited |
| Mello-Roos common | On newer tracts, $3K-$5.5K/yr | Rare; mostly none |
| Typical lot size | 6,500 - 12,000 sq ft varies | 6,000 - 10,000 sq ft varies |
| Granada Hills Charter HS feed | Most parcels | Many parcels (verify per address) |
Schools — the shared anchor
Granada Hills Charter High School (GHC) is one of LAUSD's highest-performing high schools. Many parcels in both ZIPs route to GHC, though boundaries are address-specific. Buyers prioritizing GHC assignment should confirm with LAUSD's School Finder for the specific address — not all 91344 parcels route to GHC, and a few perimeter 91326 parcels route elsewhere.
Elementary and middle school assignments vary across both ZIPs. Castlebay Lane Elementary and Frost Middle are common Porter Ranch assignments. Granada Hills has multiple elementary and middle options depending on the specific address.
Mello-Roos differential
Granada Hills inventory is largely pre-CFD era — older Pacific Enterprises and other 1960s-1990s tracts that pre-date the Mello-Roos financing model. Granada Hills buyers can find inventory with essentially no special assessments.
Porter Ranch inventory splits — older tracts (no CFD) versus newer Toll construction (substantial CFD, $3,000-$5,500/year). The 91326 buyer choosing newer Toll construction takes on the CFD obligation; the 91344 buyer typically does not.
Lot sizes and architectural character
Granada Hills tract product is typically traditional Southern California single-family on 6,000-10,000 sq ft lots — Ranch, Mediterranean, two-story Spanish styles from the 1960s through 1990s. Many homes have been remodeled at least once; older originals also exist.
Porter Ranch offers a wider mix — older tracts comparable to Granada Hills inventory, plus the Toll new construction product on hillside lots typically 6,500-9,500 sq ft. Architectural character within Porter Ranch ranges from 1970s ranches to contemporary 2020s Toll plans.
Commute and freeway access
Both ZIPs use the 118 Reagan Freeway as the primary east-west corridor. 118 east connects to the 405 in about 5-7 minutes from either ZIP, then 405 south to West LA (30 minutes typical). 118 west to Simi Valley is 15-20 minutes. North-south within the Valley uses the 405 or surface streets.
Granada Hills sits slightly closer to the 405 on average due to its more easterly position. Porter Ranch is further west, so 118 west to Simi Valley is slightly faster from Porter Ranch.
Which ZIP for which buyer
The right call depends on the buyer's specific priorities.
- Want Toll new construction with GHC school assignment? Porter Ranch (91326).
- Want lower price point with no Mello-Roos and GHC school assignment? Granada Hills (91344) at parcels confirmed routing to GHC.
- Want larger lots, mature landscape, and minimal CFD? Either ZIP's older inventory; pull the comps.
- Want master-planned community structure? Porter Ranch.
- Want maximum housing-cost efficiency? Granada Hills.
- Want hillside views? Porter Ranch upper hillside (Toll collections or older perimeter tracts).
Frequently Asked Questions
Is Porter Ranch better than Granada Hills?
Neither is universally 'better' — they serve different buyer priorities. Porter Ranch offers master-planned structure, Toll new construction, and slightly higher pricing. Granada Hills offers older tract product at lower price points with minimal Mello-Roos. Both ZIPs include many parcels routing to Granada Hills Charter HS.
Do Granada Hills homes feed Granada Hills Charter HS?
Many do, but not all — boundaries are address-specific. Some Granada Hills parcels route to alternative high schools depending on location. Always confirm with LAUSD's School Finder for the specific street address before relying on GHC assignment.
Why is Porter Ranch more expensive than Granada Hills?
Porter Ranch's premium reflects the master-planned community structure, Toll Brothers new construction available within 91326, and slightly larger lot sizes on certain tracts. Granada Hills inventory skews older tract product without contemporary new construction comparable to Toll Porter Ranch, holding the median lower.
Does Granada Hills have Mello-Roos?
Most Granada Hills inventory pre-dates the CFD Mello-Roos financing model and carries no special assessment. Some perimeter parcels or specific newer tracts may carry small CFDs. The general rule: Granada Hills is largely CFD-free; verify per parcel on the LA County tax bill.
Which has better schools, Porter Ranch or Granada Hills?
Both share Granada Hills Charter HS as a common anchor for many parcels. Elementary and middle school assignments vary by address in both ZIPs. School quality is address-specific — pull the LAUSD School Finder for the specific address you're considering rather than relying on ZIP-level generalizations.
Is the Aliso Canyon disclosure relevant in Granada Hills?
Aliso Canyon disclosure is most directly associated with Porter Ranch given the facility's proximity to the 91326 hillside. Granada Hills parcels further from the facility may have less direct disclosure exposure, but the practice and prudence of asking about disclosures applies to any home in the broader area.
Should I shop both ZIPs?
Often yes — if your priorities are GHC school feed plus a specific price point, both ZIPs have parcels meeting those criteria with different trade-offs. I help buyers run searches across adjacent ZIPs all the time. The right home may be in either.
