Pinnacle sits at the top of the Big Sky hillside, with the most ridge-line lots and the most consistent view inventory of any sub-tract in the community. The lots are the largest in Big Sky, the plans are the most generous, and the price points reflect both. May 2026 sales in Pinnacle generally start at $1.5M and run well into the $2M-plus range for ridge-line panoramic lots on the largest plan footprints. This page covers where Pinnacle sits in the master plan, what the lots and plans actually look like, what HOA and Mello-Roos exposure runs, current school boundaries, and how recent comps have moved by plan size and view category.
Where it sits inside Big Sky
Pinnacle sits at the highest elevation in the Big Sky master plan, accessed by the main community entry off Erringer Road and the collector streets that climb through the lower and middle tracts. The tract is laid out along the ridge with most lots oriented to capture the south-facing and southwest-facing view inventory across the Simi Valley basin and the surrounding mountains.
From Pinnacle, drive times to the 118 freeway at Erringer run several minutes longer than from the lower tracts, and the climb back uphill at the end of the day is a real factor. The community park, elementary school, and trail access points are all downhill. The trade-off Pinnacle makes is the extreme end of the Big Sky math: you pay for elevation in time and you get back the most consistent view inventory in the entire community.
Builder history and floor plans
Toll Brothers built Pinnacle in the late 2000s and early 2010s as the capstone of the broader Big Sky program. Plans here are the largest in the community: roughly 4,000 to 5,500 square feet, five to six bedrooms, three-car garages standard (sometimes split or expanded), and downstairs guest suites on most plans. A subset of plans includes formal libraries, bonus rooms, and primary suites with sitting areas oriented to the view side.
Architectural elevations reflect the late-2000s Toll product range: Tuscan, Mediterranean, Spanish revival, and a smaller share of Craftsman or modern interpretations. Stone-and-stucco facades, tile roofs, and deep eaves are typical. Interior finishes from original build are now 15 years old or less on the later closes; many Pinnacle homes have had either an original premium-finish package or a recent designer-grade remodel, both of which trade well on resale.
- Plan footprints generally 4,000–5,500 sq ft, 5–6 bedrooms.
- Downstairs guest suites standard on most plans.
- Three-car garages, sometimes expanded or split.
- View-oriented great rooms and primary suites on view-side lots.
- Tile roofs, stone-and-stucco elevations, deep eaves.
Lot sizes, pads, and view characteristics
Lots in Pinnacle generally run from about 10,000 to 18,000 or more square feet, with the largest ridge-line lots reaching that upper end. Pads are graded flat and the buildable yard footprint is the largest in Big Sky. Most lots support pools, built-in outdoor kitchens, and covered patios with room to spare. The slope geometry varies — some lots have a manufactured slope falling away to the rear with the view inventory below; others sit on a level ridge with neighbor pads at the same elevation.
View characteristics in Pinnacle skew strongly toward the panoramic and view-corridor categories. Interior lots exist but are a minority share of the tract, and even those typically have some view orientation because of the elevation. The premium structure here rewards true ridge-line panoramic positioning — those lots sit at the top of the price range and trade quickly when they appear.
HOA fees and what they cover
Monthly HOA dues in Pinnacle generally run about $220 to $280. That covers the master Big Sky obligations — entry monuments, community park, perimeter slopes, trail easements, and shared landscape along collector streets. Some Pinnacle sub-areas have additional sub-association contributions for private street segments or shared maintenance slopes behind a row of homes.
What the HOA does not maintain is your private rear slope (where the lot includes one), your front-yard landscape, or the fence segments on your lot. Architectural review applies to substantive exterior changes including paint, landscape redesign, and rear-yard structures. Pull the disclosure packet during your contingency period for the current fee, the reserve study, and any pending special assessments — at this price point the reserves and assessment posture matter.
Mello-Roos / CFD assessment
Pinnacle is inside the Big Sky Community Facilities District. The CFD line on the annual property tax bill in Pinnacle typically runs in the range of about $3,500 to $4,500 per year, sometimes higher on the largest lots. The original assessed values in Pinnacle were among the highest in Big Sky, which is reflected in the CFD amortization.
I do not quote a Mello-Roos number for a specific Pinnacle address without pulling the actual tax bill. The combination of the higher annual CFD and the longer remaining bond term on the later-issuance tracts makes the carrying-cost arithmetic materially different from what a buyer might estimate based on the headline price. Verify per APN and build the actual annual number into your true monthly carry.
Schools
Pinnacle addresses by current SVUSD boundary generally attend Big Sky Elementary inside the community, Sycamore Canyon K–8 / Middle, and Royal High School. District boundaries can change. Inter-district transfer, magnet program, and charter enrollment are separate processes from boundary placement. Always verify the current attendance area for the specific address with SVUSD enrollment before relying on it.
Performance and program data is published on the California School Dashboard. That is the authoritative source. If a specific program is decision-driving — AP capacity, dual-language, special education services, transportation eligibility — call the school directly. I help buyers find the data and verify the boundary; I do not characterize school quality.
Recent sale comps
The table below summarizes recent Pinnacle sale activity by plan-size band, not by address. Pricing reflects May 2026 and will move with rates and inventory. View category is the single biggest driver of the spread within each band — true ridge-line panoramic lots trade at the top, interior or view-corridor lots toward the lower end.
| Plan Size Band | Bed/Bath | Recent Sold Range | Notes |
|---|---|---|---|
| ~4,000 sq ft | 5 bed / 4.5 bath | $1.50M – $1.70M | View corridor |
| ~4,400 sq ft | 5 bed / 5 bath | $1.65M – $1.85M | Mixed view inventory |
| ~4,800 sq ft | 5–6 bed / 5 bath | $1.80M – $2.05M | View corridor to panoramic |
| ~5,200 sq ft | 6 bed / 5.5 bath | $2.00M – $2.25M | Ridge-line panoramic |
| ~5,500 sq ft | 6 bed / 6 bath | $2.20M – $2.50M+ | Top of plan range, premium lot |
Resale and view-corridor premium
Pinnacle carries the strongest view-corridor premium structure in Big Sky. Ridge-line panoramic lots trade at the top end of the tract's range with consistent demand, and on the rare interior lot the per-square-foot pricing closer resembles upper-Promontory. The 15% to 25% view premium applies cleanly here and at the high end of that range — supply is limited and the buyer pool for top-of-Big-Sky view product is real.
Days on market in Pinnacle has run in the high teens to low 20s for prepared, accurately priced listings in May 2026, with the best ridge-line homes occasionally selling in under two weeks with multiple offers. The buyer pool at this price point is informed, often working with an experienced buyer's agent, and they are comparing your home not just to other Pinnacle inventory but to comparable view-and-luxury product in Bridle Path, Wood Ranch upper tracts, and parts of Westlake.
Common buyer scenarios
Pinnacle attracts three main buyer profiles. The first is the executive trade-up — a buyer who has built equity in a starter or move-up home and is looking for the top of the Big Sky product range with view-and-lot to match. The second is the relocation buyer comparing Pinnacle against Bridle Path's larger lots and Wood Ranch's upper view tracts; the comparison usually comes down to view, plan, and price. The third is the move-down from a larger acreage property who wants the view without the land maintenance and the longer drive of a Bridle Path equestrian parcel.
For each profile the right question is different. Executive trade-up buyers should stress-test the full carrying cost including HOA, Mello-Roos, and insurance — the gap between Pinnacle and a similarly valued non-CFD property is real. Relocation buyers should walk every available view lot before deciding. Move-down buyers should look hard at primary-suite location and whether the plan supports single-level living comfortably.
- Executive trade-up wanting top-of-Big-Sky view product.
- Relocation buyer comparing Pinnacle to Bridle Path and Wood Ranch upper tracts.
- Move-down from acreage property wanting view without land maintenance.
How Pinnacle compares to Bridle Path and Wood Ranch upper-tier alternatives
Pinnacle's price point puts it in direct competition with Bridle Path and the upper-tier Wood Ranch view tracts at $1.5M to $2.5M-plus. The comparison is the most important one in the Big Sky decision tree for luxury buyers, because each option solves a different problem. Pinnacle delivers ridge-line view inventory and the Big Sky elementary boundary at the highest elevation in the tract. Bridle Path delivers larger equestrian-zoned lots and a different lifestyle product entirely — horses, larger acreage, more privacy — without the master-community trail and park infrastructure. Wood Ranch upper tracts offer view, the private country club option, and a different school boundary.
The carrying-cost differential is meaningful. Pinnacle's Mello-Roos plus HOA can add $5,000 to $6,000 a year over a comparable Bridle Path or Wood Ranch property. Wood Ranch's optional country-club initiation is a separate decision. Bridle Path's larger acreage carries larger maintenance and brush-clearance costs. None of these is categorically better — the right choice depends on what you actually want from the home. Pinnacle is the answer for buyers who want top-of-Big-Sky view, the school boundary, and the master-community infrastructure. The other tracts are the answer for different problems.
Wildfire exposure, insurance, and brush clearance
Pinnacle's ridge-line position puts the entire tract within California's designated Fire Hazard Severity Zones. This is the most important practical consideration after view itself, because the insurance underwriting picture at this elevation has tightened meaningfully in recent years and the carrying cost of the policy can be material on a $2M-plus property. Buyers should treat insurance availability and cost as a primary contingency item — pull quotes from multiple admitted carriers during the contingency period and confirm the California FAIR Plan availability as a backstop before removing the inspection contingency.
CAL FIRE defensible-space rules apply broadly across Pinnacle. The 0-5, 5-30, and 30-100 foot clearance zones extend down the ridge-line slopes on view-side lots and the slope maintenance is homeowner responsibility. Hardened building materials at the perimeter — Class A roof, ember-resistant vents, defensible eaves, tempered glass on exposed elevations — substantively lower the risk profile and can lower the quoted rate. Some Pinnacle buyers commission a wildfire mitigation assessment from a credentialed inspector during diligence to identify specific upgrades that would improve insurance outcomes, particularly if the home has not been recently updated.
- Insurance carrier quotes during contingency — multiple admitted + FAIR Plan.
- Wildfire mitigation assessment from credentialed inspector worth considering.
- Hardened materials (Class A roof, ember vents) reduce risk and rate.
- Slope brush clearance is part of the obligation on view-side lots.
What I tell clients about Pinnacle
Pinnacle is the right answer for buyers whose top priority is ridge-line view and largest-in-community lot inventory inside Big Sky. It is not the right answer for buyers prioritizing freeway-access convenience or for buyers who would actually prefer a more level in-town lot. The carrying cost gap between Pinnacle and a non-CFD comparable elsewhere in Simi Valley is real, and the calibration question is whether the view-and-lot inventory justifies it for your specific use of the home.
When I list a Pinnacle home, the preparation is comprehensive. Address every systems item before listing. Refresh interior finishes to current designer standards if the original package is dated. Stage to show how the home uses the view from every primary room. Price honestly against the actual comp set the informed buyer is using — which includes Bridle Path and Wood Ranch upper-tier comps, not just other Pinnacle listings. Aspirational pricing on a $2M Pinnacle home almost always produces a sit-and-trim cycle that ends below what the right initial list would have achieved.
Frequently Asked Questions
What makes Pinnacle different from Promontory?
Pinnacle sits at the highest elevation in Big Sky with the largest lots in the 10,000 to 18,000+ square foot range and the largest plans at 4,000 to 5,500 square feet. Promontory sits just below it with slightly smaller lots and plans, trading $1.4M to $2.0M versus Pinnacle's $1.5M to $2.5M+ range. View inventory is strong in both but the ridge-line panoramic lots are most concentrated in Pinnacle.
How much is Mello-Roos in Pinnacle?
CFD assessments in Pinnacle typically run about $3,500 to $4,500 per year, sometimes higher on the largest lots. Original assessed values in Pinnacle were among the highest in Big Sky, which is reflected in the CFD amortization. Pull the actual property tax bill for the specific APN — adjacent lots can differ meaningfully and the remaining bond term matters.
Are all Pinnacle lots view lots?
Most are, because of the elevation, but not all. A minority of interior lots exist within the tract and trade at the lower end of the Pinnacle price range. True ridge-line panoramic lots are the most desirable and trade at the top of the range with the best demand. Rank the view category of any specific lot honestly before writing the offer; not every Pinnacle address is a panoramic.
Is Pinnacle gated?
No. Big Sky as a master community is not fully gated and Pinnacle does not have its own private entry gate. Access is through the main Big Sky entrance off Erringer Road and the interior collector streets that climb to the top of the hill. If gated access is a priority see the Simi Valley gated community filter page for cross-neighborhood options.
What schools serve Pinnacle?
By current SVUSD boundary, Pinnacle addresses generally attend Big Sky Elementary, Sycamore Canyon K–8 / Middle, and Royal High School. Boundaries can change. Always verify the current attendance area for the specific address with SVUSD enrollment. Magnet, charter, and inter-district transfer programs are separate processes from boundary placement.
How long do Pinnacle homes stay on the market?
May 2026 has run in the high teens to low 20s on median days on market for prepared, accurately priced Pinnacle listings. Best-in-class ridge-line homes have occasionally sold in under two weeks with multiple offers. The buyer pool at this price point is informed and is comparing your home not just to Pinnacle inventory but to comparable luxury view product in Bridle Path and Wood Ranch.
What is the HOA in Pinnacle?
Monthly dues generally run about $220 to $280. The master HOA covers community common areas including entry monuments, park, perimeter slopes, trail easements, and shared landscape on collectors. Some Pinnacle sub-areas have additional sub-association contributions for private streets or shared slopes. Pull the current disclosure packet during contingency for the actual fee and reserves.
Is Pinnacle in a wildfire hazard zone?
Yes — the upper hillside elevation puts much of Pinnacle in California's designated Fire Hazard Severity Zones. Address this through brush clearance, hardened building materials, and serious insurance shopping with multiple carriers. CAL FIRE publishes the maps. Carriers have tightened underwriting in California hillside areas and insurance availability and cost should be verified before removing contingencies.
