Hidden Hills is the only incorporated city in California that's also a mandatory-equestrian-zoned guard-gated community. The whole city — about 1.6 square miles, roughly 660 homes — sits inside one perimeter, accessed through three guard gates. Every parcel is at least 1 acre with horse-keeping rights. Las Virgenes USD's Round Meadow Elementary sits inside the gates. The May 2026 median is north of $8M, and the post-Woolsey rebuild pipeline is still running. I sell Hidden Hills alongside Calabasas, Bell Canyon, and the broader equestrian belt. I'm Brian Cooper. DRE# 01434286.
Where Hidden Hills sits
Hidden Hills is an incorporated city in Los Angeles County, separate from Calabasas though it shares ZIP code 91302. The city covers approximately 1.6 square miles and holds about 660 homes inside a continuous perimeter. Three guard gates control access: the Long Valley gate on the south, the Spring Valley gate on the north, and the Jed Smith gate on the east. The city was incorporated in 1961 as a general-law city to preserve the equestrian character against encroaching valley development.
Government is council-manager. A five-member city council operates with rotating mayoral appointments. The city contracts most public safety: LA County Sheriff Lost Hills station for law enforcement; LA County Fire for fire and EMS. Planning and code enforcement are handled in-house with a small city staff. Architectural review is a joint city / Community Association function and is among the strictest in the region.
The city sits in the Santa Monica Mountains foothills, bordered by Calabasas to the south and west, and unincorporated LA County to the north and east. The 101 freeway runs along the southern edge — access is via Long Valley Road from the 101 at Valley Circle, or via Mureau Road. Drive time to Calabasas is five minutes, to Westlake Village 18 minutes, to Burbank Airport 30-35 minutes via the 101 east.
Mandatory equestrian zoning and parcel requirements
Hidden Hills is one of a small handful of California municipalities where equestrian zoning is mandatory citywide. There is no non-equestrian zone. Every parcel in the city carries horse-keeping rights and corresponding responsibilities. The minimum lot size is 1 acre with no exceptions — subdivision below 1 acre is prohibited by the city's general plan and zoning code. Most parcels actually run 1 to 3 acres; a few exceed 5.
Specific horse-keeping rules: corrals require a 70-foot setback from any dwelling on a neighboring parcel and a 25-foot setback from the property line. Stables require a city building permit regardless of square footage. Manure storage must be covered and removed weekly per city nuisance code. The architectural review committee — staffed by both city and Community Association volunteers — reviews every new corral, stable, arena, and fence before construction. The review timeline can run 8-16 weeks; plan accordingly.
Trail easements are recorded across most Hidden Hills parcels. The Community Association maintains 30+ miles of internal private trails — a network exclusive to Hidden Hills residents and their guests. Trail easements run with the land and are perpetual. Title reports will show the easement footprint; ask escrow to plot the easements on the parcel map before close because they affect where you can build, fence, or place outbuildings.
- Mandatory citywide equestrian zoning — no non-equestrian parcels
- 1-acre minimum (no subdivision below 1 acre)
- 70-foot corral setback from neighboring dwellings
- City building permit required for any stable
- Manure storage covered with weekly removal minimum
- Architectural review for all new construction — 8-16 week timeline typical
- 30+ miles of HCA-maintained private trails
Price tiers and recent comps
Hidden Hills closed May 2026 at a median sale price of approximately $8.2M across roughly 6-10 closings in the prior 90 days. Active inventory typically runs 18-30 listings. Days on market average 65, the slowest of any community I cover, driven by the price tier and the narrow buyer pool at the top end. The range spans from $5M for older homes due for renovation up to $20M+ for newly built large estates on premier parcels.
Post-Woolsey new construction is a significant share of the inventory. The 2018 fire burned through portions of the city and the rebuild pipeline ran from 2019 through 2024 with a smaller tail continuing today. Newly built homes with current code compliance — fire-hardened construction, defensible space designed in, modern mechanicals — trade at a premium of 15-30% over comparable older inventory. The premium reflects both build quality and reduced insurance friction.
| Tier | Description | May 2026 range |
|---|---|---|
| Entry | Older home due for renovation, 1 acre | $5M - $7M |
| Core | Updated home on 1-1.5 acre with facility | $7M - $10M |
| Premium | Renovated or rebuilt on 1.5-2 acre | $10M - $15M |
| Top | Newly built large estate, 2+ acres, premier lot | $15M - $25M+ |
Schools serving Hidden Hills
All of Hidden Hills is served by Las Virgenes Unified School District (LVUSD), the same district that serves Calabasas, Agoura Hills, and Westlake Village west of the 405. Uniquely, the elementary campus assigned to Hidden Hills — Round Meadow Elementary — sits inside the city's gated perimeter, which is rare for a public elementary school. Middle school is A.E. Wright Middle School in Calabasas. High school is Calabasas High School, also outside the gates.
Round Meadow's location inside the gates is a feature of the city's original 1961 incorporation — the campus predates the gating in its current form and was retained when the city formalized the perimeter. Non-resident LVUSD families enrolled at Round Meadow can enter through the guard gates with school-list clearance.
LVUSD performs above the LA County median on the California School Dashboard and has held that performance through multiple superintendent cycles. Specific campus assignments are published at lvusd.org and should be verified for any specific address before tying a purchase to a school assumption. I do not steer buyers to or from particular campuses.
Hidden Hills Community Association and the trail system
The Hidden Hills Community Association (HCA) is the homeowners association that operates the three guard gates, maintains the 30+ mile internal private trail network, runs architectural review jointly with the city, and operates the community center and recreation facilities. HCA dues in May 2026 run approximately $7,500-$9,500 per year depending on parcel and category. The dues are a meaningful line item but they fund a meaningful infrastructure.
The trail system is the defining amenity. Trails connect from the eastern, southern, and western edges of the city to internal arterial paths that thread through every neighborhood. Riders can leave the property and reach any other point in the city — and most of the perimeter — without trailering. External trail access to Upper Las Virgenes Canyon Open Space and the Cheeseboro corridor is available via designated trailheads.
Architectural review is among the strictest in California. New construction and major renovation require HCA architectural review committee approval before the city issues a building permit. The review covers massing, setbacks, materials, landscaping, lighting, and how proposals interact with trail easements. Review timelines run 8-16 weeks for a normal proposal and longer for non-standard designs.
Hazards: Woolsey 2018 burn area, defensible space, and insurance
All of Hidden Hills sits inside a CAL FIRE Very High Fire Hazard Severity Zone. The Woolsey Fire of November 2018 burned through portions of the city, destroying dozens of homes and damaging more. The rebuild pipeline ran from 2019 through 2024 with a smaller continuing tail. Today's inventory therefore splits into pre-Woolsey older construction and post-Woolsey new construction, with the new-build segment carrying both an aesthetic premium and an insurance-bind advantage.
Defensible space follows PRC 4291 plus city additions. 100 feet of cleared defensible space around all structures. Stables, hay storage, and outbuildings each carry their own clearance. The city's local fire code adds requirements around hay storage construction and corral fencing materials within 30 feet of structures. Annual fire inspection by LA County Fire is mandatory. Non-compliance triggers a city citation and frequently an insurance cancellation.
Insurance is the largest closing risk on Hidden Hills inventory. Most homes today bind through California Fair Plan for the dwelling plus a surplus-lines wrap policy for stable structures, contents, and liability. Annual premiums frequently run $15,000-$45,000+ on the larger homes, with the variance driven by structure values, defensible-space compliance, build year, and prior claim history. Large-animal evacuation routes from Hidden Hills go via Long Valley or Mureau to Pierce College in Woodland Hills and to the LVUSD bus depot.
Well water, septic, and utility considerations
Hidden Hills is on Las Virgenes Municipal Water District municipal water — not private wells. Sewer service is mixed: portions of the city are on LV Municipal sewer; significant portions remain on private septic. Confirm sewer-versus-septic status for the specific parcel in escrow. Septic systems require inspection including tank pump-out and leach-field perc test. Stable wash water cannot enter the household septic and must be diverted to a separate sand filter or evapo-transpiration drain.
Power is Southern California Edison. Gas is SoCal Gas. Most homes have propane backup for indoor cooking due to historical gas-service interruptions during fire events. Several homes have whole-home solar with battery backup given the elevated wildfire-related grid-event frequency. Cellular and broadband coverage have improved meaningfully but remain spottier than the valley floor — confirm carrier-specific service at the parcel.
Common buyer scenarios in Hidden Hills
The high-net-worth buyer who actually rides is the historical core of the Hidden Hills buyer pool. For this buyer the combination of mandatory equestrian zoning, the 30-mile private trail system, Round Meadow inside the gates, and the architectural standards holds together as a single lifestyle package. Bell Canyon and Old Agoura are the realistic comp communities; Hidden Hills competes on schools, gates, and trails.
The privacy-priority buyer who tolerates equestrian zoning is the modern expansion of the buyer pool. Strict architectural review, three guard gates, and the city-as-HOA structure deliver privacy that's hard to replicate. The 1-acre minimum lot size and the mandatory horse-keeping rights are accepted as features rather than friction. The Oaks of Calabasas and Mulholland Estates are the realistic competition.
The post-Woolsey rebuilder is a distinct subcategory. Buyers acquiring a burn-site lot or a newly built post-Woolsey home benefit from a more predictable insurance path and a cleaner permitting record. These transactions carry a different risk profile than older inventory and should be underwritten differently. Confirm permits, certificate-of-occupancy, and post-rebuild warranty status during escrow.
What I tell clients about Hidden Hills
Hidden Hills is a singular product — there is nothing else in California that combines incorporated-city status, mandatory equestrian zoning citywide, three guard gates, and a public elementary inside the perimeter. That singularity is the basis for the price premium and the basis for the slower days-on-market. Buyers either understand the product or they don't; there's not much middle ground.
The two biggest preventable mistakes I see: anchoring on lot size without running the trail-easement footprint, and writing an offer before getting an insurance quote in writing. The Woolsey burn shadow and the architectural-review timeline both deserve serious attention before contingency removal. If you want to compare Hidden Hills against Bell Canyon, Calabasas gated product, or Westlake gated communities, I run that comparison honestly and will steer you out of Hidden Hills if it's the wrong fit.
Frequently Asked Questions
Is Hidden Hills a separate city from Calabasas?
Yes. Hidden Hills is an incorporated city of approximately 660 homes within LA County, separate from Calabasas though it shares ZIP code 91302. Hidden Hills was incorporated in 1961 as a general-law city to preserve the equestrian character. The city has its own five-member council, its own planning department, and its own municipal services contracts with LA County Sheriff (Lost Hills station) and LA County Fire. Calabasas, by contrast, was incorporated in 1991 and is a much larger city without mandatory equestrian zoning.
Are all Hidden Hills homes equestrian-zoned?
Yes. Hidden Hills is one of a small number of California municipalities with mandatory citywide equestrian zoning. There is no non-equestrian zone within the city. Every parcel carries horse-keeping rights and corresponding setback and structure requirements. The minimum lot size is 1 acre citywide with no subdivision exceptions. Most parcels are 1 to 3 acres, with a small number exceeding 5. The zoning structure is foundational to the city's identity and is protected by both the general plan and the Community Association CC&Rs.
What is the median price in Hidden Hills?
Hidden Hills closed May 2026 at a median sale price of approximately $8.2M across roughly 6-10 closings in the prior 90 days. Days on market average 65 — among the slowest in the region, driven by the price tier and the narrow buyer pool. The range runs from $5M for older homes due for renovation up to $20M+ for newly built large estates. Post-Woolsey new construction commands a 15-30% premium over comparable older inventory because of current fire-code compliance and easier insurance bind.
What schools serve Hidden Hills?
All of Hidden Hills is served by Las Virgenes Unified School District (LVUSD). Uniquely, the elementary campus — Round Meadow Elementary — sits inside the city's gated perimeter, which is unusual for a public elementary school. Middle school is A.E. Wright Middle School in Calabasas. High school is Calabasas High School, also outside the gates. Non-resident LVUSD families enrolled at Round Meadow access the campus through the guard gates with school-list clearance. Verify specific assignments at lvusd.org before tying a purchase to a school assumption.
What does the Hidden Hills Community Association cover?
The HCA operates the three guard gates, maintains the 30+ mile internal private trail network, runs architectural review jointly with the city, and operates the community center and recreation facilities. Annual dues in May 2026 run approximately $7,500-$9,500 depending on parcel and category. The HCA is mandatory; ownership of any Hidden Hills parcel automatically includes HCA membership. Architectural review is among the strictest in California — plan for an 8-16 week review timeline on new construction or major renovation.
How was Hidden Hills affected by the Woolsey Fire?
The November 2018 Woolsey Fire burned through portions of Hidden Hills, destroying dozens of homes and damaging more. The rebuild pipeline ran from 2019 through 2024 with a smaller continuing tail. Today's inventory therefore splits into pre-Woolsey older construction and post-Woolsey new construction. Post-Woolsey homes carry both an aesthetic premium and an insurance-bind advantage because they were built to current fire-hardened code with defensible space designed in. Verify build year and whether a property was a post-Woolsey rebuild during diligence.
Can I insure a Hidden Hills home in 2026?
Yes, but insurance is the single largest closing risk in this market. Most homes bind through California Fair Plan for the dwelling plus a surplus-lines wrap policy for stable structures, contents, and liability. Annual premiums frequently run $15,000-$45,000+ on larger homes, with variance driven by structure values, defensible-space compliance, build year, and claim history. Start the quote process the day escrow opens. Build a 21-day insurance contingency into your offer when possible. Confirm current defensible-space inspection before binding.
How do the guard gates work for guests and contractors?
Hidden Hills has three guard gates: Long Valley on the south, Spring Valley on the north, and Jed Smith on the east. All visitors and contractors must be cleared by the guard before entry. Residents can pre-clear guests via the HCA system or by phone. Contractors require a current contractor list approval. The gates are staffed continuously. The security infrastructure is funded through HCA dues. School families for Round Meadow Elementary enter through gates with school-list clearance during school hours.
