Santa Susana Knolls sits in the foothills of the Santa Susana Pass at Simi Valley's eastern boundary. Originally developed as a mountain getaway in the 1920s, the Knolls has retained much of its historic character — narrow winding streets, mature oaks, hand-built stone walls, and architecturally diverse homes that range from 1920s craftsman cottages to mid-century moderns to a handful of newer custom builds. The neighborhood feels distinctly different from the rest of Simi Valley's tract-built suburban areas.

Typical Home Style
The Knolls' housing stock is the most architecturally diverse in Simi Valley. You'll find original 1920s mountain cottages (often 800–1,400 sqft, two bedrooms, one bath), 1940s–1960s ranches and bungalows, mid-century moderns, and a handful of post-2000 custom builds where original homes were torn down and replaced. Lot sizes vary widely — some are tiny (3,500 sqft), others are unusually large for Simi Valley (over half an acre on the slopes). Topography is hilly, with many homes accessed by long driveways or staircases.
School Zones
Most of the Knolls feeds Knolls Elementary School and Sycamore Elementary, both within Simi Valley Unified School District (SVUSD). Middle school is Hillside; high school is Royal HS. SVUSD boundaries are subject to change — verify the specific address with SVUSD enrollment at (805) 520-6500 before buying based on a school zone.
HOAs and Special Considerations
The Knolls is HOA-free for the vast majority of homes — there's no master-planned community structure. That said, the area carries significant unique considerations buyers must understand:
- Septic systems are common. Many older Knolls homes are not on city sewer — they have private septic tanks. A septic inspection (separate from the standard home inspection) is essential. Replacement runs $8,000–$25,000+ depending on system size and access.
- Wildfire risk zone. The Knolls is in a Cal Fire designated High Fire Hazard Severity Zone. AB 38 defensible space requirements apply (100 feet around structures). Insurance can be expensive or difficult to obtain — get a quote BEFORE removing your inspection contingency.
- Topography access. Hillside lots may have driveway grades that limit truck access (movers, deliveries) or have staircase-only entry to the front door.
- Older infrastructure. Many homes still have original electrical panels, galvanized plumbing, or roofs at end of life. Budget accordingly.
Things to Do Nearby
The Knolls is steps from Santa Susana Pass State Historic Park (hiking, picnic areas, the historic Stagecoach Trail). Corriganville Park is just east — popular for its film history and family-friendly trails. Downtown Simi Valley is 10 minutes west via Kuehner Drive, putting Tapo Canyon shops, restaurants, and the Reagan Library within easy reach. The 118 freeway is 5 minutes; you're 50 minutes to Burbank, 65 minutes to downtown LA off-peak.

Active Listings
The Knolls typically has 5–9 active listings at any given time. Currently the active range runs from approximately $725,000 (a small 1,000-sqft cottage) to $1.45M (a renovated 4-bed). Inventory turns slower here than in Simi Valley's tract neighborhoods because of the unique buyer pool.
Resident Perspective
"What I love most about the Knolls is the quiet — and the trees, and not having a tract behind me," one longtime resident put it. "What I'd warn buyers about is the septic, the insurance hunt, and that you have to actually like a 1940s house with all that means. It's not for everyone, but for the people it's for, nothing else in Simi compares." That summary captures the trade-off honestly: privacy and character on one side, infrastructure surprises and insurance complexity on the other.
Frequently Asked Questions
Is the Santa Susana Knolls a good neighborhood for first-time buyers?
Sometimes. Knolls homes are smaller and often less expensive than newer Simi Valley tracts, but the older infrastructure (septic, electrical, roof) means inspection findings often push deferred-maintenance costs onto a first-time buyer's plate within 3–5 years. If you're handy and have a $10K–$25K reserve for surprises, it can work. If you need turnkey, look elsewhere in Simi Valley.
Do all Knolls homes have septic systems?
Most do, but not all. Some properties — particularly newer ones and those closer to the western edge — connect to city sewer. Always confirm with the seller and request the septic inspection report. The Knolls' rural infrastructure history means city sewer was never extended to all parcels.
Is fire insurance hard to get in Santa Susana Knolls?
Yes, increasingly. Most major California insurers have non-renewed policies in High Fire Hazard Severity Zones in the past several years. Buyers often have to use the California FAIR Plan plus a wraparound policy. Premiums can run $3,500–$6,500/year for a typical Knolls home — verify a quote before removing your inspection contingency.
What schools serve the Knolls?
Knolls Elementary, Sycamore Elementary, Hillside Middle, and Royal High School (all SVUSD). Always verify the specific address with SVUSD enrollment at (805) 520-6500 — boundaries are reviewed periodically and change happens.
Are there any HOAs in the Knolls?
Almost none. The Knolls developed organically rather than as a master-planned community, so there's no overarching HOA. A small handful of more-recent custom developments may have private maintenance agreements — check the title and CC&Rs.
Can I tear down an older Knolls home and rebuild?
Yes, but it's not as simple as in flat tract neighborhoods. Hillside grading triggers additional Simi Valley city review, and slope-stability and fire-egress requirements add cost. New construction in the Knolls runs $400–$700/sqft depending on slope and access. Always consult Simi Valley Planning before committing.
How does the Knolls commute compare to the rest of Simi Valley?
Slightly faster to the 118 freeway entry at Kuehner Drive (5 minutes from most of the Knolls). Once on the 118, your commute to LA matches the rest of Simi — about 50 minutes to Burbank, 65 minutes to downtown LA off-peak.
