Santa Susana Pass State Historic Park is the 670-acre state park straddling the Chatsworth-Simi border, preserving the original stagecoach grade and the old western film locations used by John Ford, Republic Pictures, and a generation of TV westerns. I'm Brian Cooper at eXp Realty, and this is the guide to the small ring of Chatsworth homes that back to or walk to the park boundary — what's available, what it costs, and what the FHSZ math looks like.
What Santa Susana Pass State Historic Park Is
The park preserves 670 acres of chaparral hillside spanning the Santa Susana Pass between Chatsworth and Simi Valley. It protects the original wagon cuts of the Butterfield and Coast Line Stage routes, the Iverson Movie Ranch filming locations that doubled for nearly every TV and B-movie western from the 1930s through the 1960s, and a robust network of hiking and equestrian trails.
From a real estate standpoint, the park is one of the most valuable amenities on this side of Chatsworth. Properties that back to or walk to the park edge get permanent open-space views and trail access that cannot be replicated by future development.
Which Streets Touch the Park
Streets with direct park-edge or park-walking access include Old Stagecoach Trail, Cyclone Street, Iverson Road, upper Andora Avenue, parts of Larwin Avenue, and a handful of small connector streets in the hills. The Chatsworth side of the park is the south boundary; Simi Valley properties touch the north and west boundaries.
Park-edge lots are scarce. Most are larger hillside parcels built between the 1970s and the 2000s, with some scattered earlier inventory. New construction in the immediate park-edge corridor is essentially nonexistent. The land is taken or the topography prohibits.
Trail and Recreation Access
The park's trail network connects to the Old Stagecoach Trail, Chatsworth Park South, and the longer Backbone Trail extensions. Trail runners, mountain bikers, and equestrians use the network heavily. The Iverson Movie Ranch trail loop is a popular Saturday morning destination for residents and visitors.
For equestrians, park access from a K-zoned home with a recorded trail easement is one of the strongest amenity profiles available in the City of LA. You leave the property, you're on state park dirt in minutes, and the trail network connects for hours of riding without crossing a paved road.
Fire Zone Reality
The entire park-edge corridor sits inside CAL FIRE's Very High Fire Hazard Severity Zone. The park itself burns periodically — most recently in the 2019 Easy Fire and earlier in the 2003 Simi Fire. Defensible space requirements are aggressively enforced on properties at the park boundary because the brush load on park land creates a direct ignition risk.
Insurance markets in 2026 reflect this. Standard carriers are not writing. FAIR Plan plus wraparound is the standard solution, running $5,000-$9,000 a year on a $1.5M-$2.2M park-edge home. Ongoing brush clearance contracts add another $1,000-$2,000 a year.
Pricing and Inventory in May 2026
May 2026 park-edge inventory: standard 3-bedroom hillside homes $1.3M-$1.6M, updated 4-bedrooms $1.6M-$2.1M, K-zoned parcels with stable improvements $2.2M-$2.8M, larger equestrian compounds $3M-$4.5M. The park-edge premium versus comparable non-park-adjacent Chatsworth inventory is roughly 8-15%, primarily for the protected view and trail access.
Days on market in this pocket are longer than the Chatsworth average. 40-65 days is typical because the buyer pool is narrower — fire zone, hillside, equestrian preference, and budget all combine to filter the audience.
What to Verify Before Writing
Pull the FHSZ status by address, confirm any recorded easement onto park trails, verify the K-suffix zoning if equestrian use matters, request defensible space compliance documentation, and review the roof age and rating. A Class A roof is required for most carriers writing in FHSZ.
I also recommend pulling the LADBS permit history. Some older park-edge homes carry unpermitted additions or hardscape that complicates appraisal and lending. Better to know before contract than after.
Frequently Asked Questions
What is Santa Susana Pass State Historic Park?
A 670-acre California state park spanning the Santa Susana Pass between Chatsworth and Simi Valley. It preserves original Butterfield Stage wagon cuts, the Iverson Movie Ranch filming locations used by Hollywood from the 1930s through 1960s, and a major hiking and equestrian trail network. It is one of the most valuable amenities on the Chatsworth side.
Can I walk into the park from my house?
From specific park-edge addresses on Old Stagecoach Trail, Cyclone Street, Iverson Road, and the upper Andora corridor, yes. Some properties have recorded easements directly onto the park trail network. Others walk to a public trailhead within a few minutes. Park-edge inventory is scarce and rarely turns over.
How much do park-adjacent Chatsworth homes cost?
May 2026 inventory: standard 3-bedroom hillside homes $1.3M-$1.6M, updated 4-bedrooms $1.6M-$2.1M, K-zoned equestrian parcels $2.2M-$2.8M, larger compounds $3M-$4.5M. The park-edge premium over comparable non-adjacent Chatsworth inventory is roughly 8-15%, primarily for the protected view and trail access.
Are park-adjacent homes in a fire zone?
Yes, essentially all of them. The corridor sits inside CAL FIRE's Very High Fire Hazard Severity Zone. The park itself burns periodically, most recently in the 2019 Easy Fire. Defensible space compliance is aggressively enforced at the park boundary. Insurance budgets $5,000-$9,000 a year on a $1.5M-$2.2M home using FAIR Plan plus wraparound.
Is there equestrian access from the park area?
Yes. Park-edge K-zoned homes have some of the best equestrian access in the City of LA. The trail network connects into the Old Stagecoach Trail and Chatsworth Park South systems. Riders can leave the property and stay on dirt for hours without crossing a paved road. This is the strongest amenity in the corridor.
