Builder participation in a master plan can change over time. This guide explains how to verify whether Toll Brothers is currently active at Williams Ranch in Castaic and how to evaluate it if so.
Builder lineups at master plans like Williams Ranch change as phases sell out, so first confirm whether Toll Brothers currently has active offerings there directly with the builder and the master developer. If active, verify pricing, phases, HOA, and per-parcel Mello-Roos before writing. The Brian Cooper Real Estate Team serves the Santa Clarita Valley from our Simi Valley headquarters.
First, confirm current participation
Which builders are selling in a master plan shifts as phases open and close. Before evaluating a Toll Brothers home at Williams Ranch, confirm directly that they currently have active inventory or to-be-built homes there. Marketing materials can lag actual availability.
If Toll Brothers is active
- Confirm released homesites, plans, and current base pricing.
- Ask for the standard-features list and options price sheet.
- Confirm HOA dues and any sub-association.
- Verify the parcel's Mello-Roos / CFD exposure from disclosures and tax records.
- Get the completion timeline and contingencies in writing.
Mello-Roos and HOA 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.
Why bring your own agent
You can have your own buyer's agent represent you when you buy from a builder, and the on-site sales team works for the builder, not for you. Bringing the Brian Cooper Real Estate Team to your first visit (and registering us at that first visit) costs you nothing extra and gives you an advocate for contract terms, inspections, walk-throughs, and timeline accountability. The Brian Cooper Real Estate Team serves the Santa Clarita Valley from our Simi Valley headquarters.

Frequently Asked Questions
Is Toll Brothers currently building at Williams Ranch?
Builder participation changes as phases sell out, so confirm current activity directly with the builder and the master developer. We verify which builders are active before you tour.
Can I use my own agent when buying a new-construction home?
Yes. You have the right to your own representation when buying from a builder. The on-site sales staff represent the builder's interests. In most communities you should bring your agent to your first visit and register them at that time. Brian Cooper serves the Santa Clarita Valley from our Simi Valley headquarters.
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 if Toll Brothers isn't active there now?
We'll identify which builders currently have active homes at Williams Ranch and elsewhere in the SCV that match your needs, and represent you with whichever you choose.
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.
