The Lake Hills area of Castaic developed through production homebuilding over time. This guide outlines that history and what resale buyers in the area should verify.
Lake Hills in Castaic is an established, largely built-out area that trades as resale, built by production builders in phases. For any specific home, confirm the actual builder, tract, year built, and any Mello-Roos from property records and disclosures. The Brian Cooper Real Estate Team serves the Santa Clarita Valley from our Simi Valley headquarters.
How Lake Hills developed
The Lake Hills area of Castaic was built out by production homebuilders in phases, producing a range of plans and lot sizes across its tracts. Today it trades almost entirely as resale. Builder names and construction years vary by tract, so verify per home.
Castaic context
Castaic sits at the north end of the Santa Clarita Valley in Los Angeles County, with its own commute, school, and amenity considerations. Some buyers also weigh wildfire and insurance factors in hillside areas; we can point you to local resources.
Where new construction is actually selling in Castaic now (mid-2026)
Lake Hills itself trades as resale, but if you want a genuinely new home in Castaic, the main active master-planned community in mid-2026 is Williams Ranch (in the Hasley Canyon area, a separate part of Castaic from Lake Hills).
Williams Ranch — Williams Homes
Williams Ranch is a ~430-acre master-planned community of roughly 497 homes by Williams Homes (a joint venture with IHP Capital Partners). As of mid-2026 it was actively selling, with marketing showing 3–5 bedrooms, roughly 2,479–4,872 sq ft, large pool-sized lots, and pricing reported from around the high $800,000s to low $900,000s (mid-2026 — verify current pricing and availability directly with the builder). Around half the homes were reported complete as of 2025, and the community's neighborhood park had opened; resident amenities (recreation center, pool/spa, amphitheater) were marketed as part of the build-out. Confirm which neighborhoods and phases remain open directly with Williams Homes.
What resale buyers should verify
- Actual builder, tract, and year built from records.
- A buyer's inspection appropriate to the home's age and any hillside considerations.
- The parcel's tax bill for Mello-Roos.
- Comparables within the same tract and plan series.
Mello-Roos in Castaic
In the Santa Clarita Valley, Mello-Roos (Community Facilities District) special taxes are often materially higher than what buyers see in Ventura County, and the amount varies tract by tract. There is no single SCV figure to quote. The only reliable way to know the annual special-tax burden is to review the specific parcel's tax bill and the CFD disclosures the builder must provide. We verify this per parcel before you commit.

Frequently Asked Questions
Is Lake Hills in Castaic new construction?
No. It's an established, largely built-out area that trades as resale. Confirm a specific home's builder, tract, and year built from property records.
How much is Mello-Roos here?
There is no single figure. In the SCV, Mello-Roos special taxes are typically higher than in Ventura County and vary by tract and parcel. Review the specific parcel's tax bill and the builder's CFD disclosures to learn the actual annual amount before you commit.
What should I inspect in a Castaic hillside home?
Order a buyer's inspection appropriate to the home's age, and in hillside areas consider drainage, grading, and any geologic factors. We coordinate the right inspections for the property.
Are there wildfire and insurance considerations in Castaic?
Some Castaic areas warrant attention to wildfire risk and insurance availability. We can point you to local resources and factor this into your decision; confirm coverage and cost before you commit.
What about interest rates and builder buydowns?
As a general 2026 reference, conventional 30-year rates have run roughly in the 6.5%-7.0% range, and builders sometimes offer rate buydowns that can reach into the high 4s on specific quick-move-in homes through their preferred lender. These offers change frequently and have conditions; verify current terms with the builder and compare against an outside lender.
Are the prices and phases on this page current?
No. This page is general guidance only and intentionally avoids quoting prices, phase availability, floor-plan sizes, completion dates, or incentive specifics, because they change constantly. Confirm all current details directly with the builder.
