Regency at Ten Trails

Independent Assessment

Regency at Ten Trails was confirmed as a genuine, actively developing, age-qualified 55+ community, with Toll Brothers' own July 2022 groundbreaking announcement explicitly describing it as 'the Company's first 55+ active-adult community in the Pacific Northwest.' Regency at Ten Trails is a distinct, purpose-built 55+ enclave within the larger, mixed-age Ten Trails master plan, and should not be confused with nearby all-ages communities. Because the community was still under active construction and sales as of the last update, buyers should confirm current phase, available inventory, and build-out timeline directly with the Toll Brothers sales office rather than assuming the community is complete.

Who May Find This Community Appealing

Buyers who want a newer-construction, single-story 55+ home from a national builder with a builder warranty, within a larger master-planned community offering broader retail and trail amenities, are a strong fit for Regency at Ten Trails. Its South King County location in Black Diamond, with access to SeaTac Airport and major highways, also suits buyers who want a smaller-town, less dense setting while remaining within reach of the greater Seattle metro.

Homes, Builders & Development History

Toll Brothers broke ground on Regency at Ten Trails in July 2022, describing it as the company's first 55-and-older active-adult community in the Pacific Northwest, planned for 403 single-story homes within the larger, roughly 4,500-residence Ten Trails master-planned community in Black Diamond. The community offers multiple home collections, including the Eclipse Collection (up to roughly 1,590 square feet), the Solstice Collection (2-3 bedrooms, up to roughly 2,055 square feet), and the Horizon Collection (up to roughly 2,379 square feet with 3-car garages), with homes generally featuring 2-3 bedrooms, 2-3 baths, and 2-3 car garages. As of the last update, construction and active new-home sales remained ongoing, with some listings showing move-in dates as recent as summer 2026.

Current Pricing & Market Positioning

Reported new-construction pricing at Regency at Ten Trails starts from roughly the mid-$600,000s, varying by home collection, floor plan, and lot. Because the community is still actively selling and building, buyers should request current builder pricing and available lot/collection inventory directly from the Toll Brothers sales office, alongside any early resale comparables from buyers who have already closed.

New Construction vs. Resale Considerations

As of the last update, Regency at Ten Trails remained under active construction with new-construction inventory and builder incentives available directly through Toll Brothers, alongside an emerging resale market from buyers who have already closed. Buyers should confirm current available lots, collections, and estimated completion dates with the Toll Brothers sales office, and resale buyers should still budget for a standard inspection despite the community's relatively young age.

Taxes, Insurance & Special Assessments

Homes in Regency at Ten Trails are subject to King County property tax at the county's current rate for Black Diamond, along with any applicable Ten Trails master-plan assessments. Washington offers a Senior Citizen and Disabled Persons Property Tax Exemption/Deferral program for qualifying homeowners at least 61 years old with King County income limits reported roughly between $60,000 and $84,000 for 2026, separate from this community's 55+ HOA eligibility threshold; buyers should confirm current eligibility and exact rates directly with the King County Assessor's Office.

Community Layout & Lifestyle

Regency at Ten Trails offers newer-construction, single-story living within a dedicated 55+ enclave inside the larger, mixed-age Ten Trails master plan, giving residents access to both their own age-restricted clubhouse and amenities plus the broader master community's trails and future retail as Ten Trails continues to build out. Because the community remained under active construction as of the last update, buyers can expect a streetscape mixing completed, occupied homes with newer construction and model homes across its various collections.

Shopping, Healthcare & Airport Access

Regency at Ten Trails is located in Black Diamond, Washington, in South King County, with its clubhouse and sales center at 33572 Douglas Ave SE, Black Diamond, WA 98010. Black Diamond offers convenient access to major highways connecting to SeaTac Airport and the greater Seattle metro, while remaining a smaller, historically coal-mining town with its own developing town center as the broader Ten Trails master plan builds out.

Age Qualification & Material Ownership Restrictions

Regency at Ten Trails is described by Toll Brothers' own materials as an age-qualified 55+ community, requiring at least one household member to be 55 or older, consistent with the federal Housing for Older Persons Act (HOPA) framework. The exact recorded covenant percentage or age-floor language for the community's specific declaration was not independently reviewed; buyers should confirm current age-verification procedures directly with Toll Brothers or the Ten Trails HOA before purchasing.

Tradeoffs & Limitations

Because Regency at Ten Trails is still under active construction, buyers should expect ongoing nearby building activity for some time and should confirm the current construction phase and completion timeline before purchasing. Black Diamond is a smaller, historically rural town, so buyers should weigh the tradeoff between newer construction and a less-established retail and healthcare infrastructure compared with more central Eastside or Seattle-area locations. As with any new-construction community, early buyers should also confirm HOA dues, reserve funding, and the transition timeline from developer to resident control with Toll Brothers and the Ten Trails HOA.

Comparison With Nearby Communities

Compared with the fully built-out, resale-only Trilogy at Redmond Ridge and the decades-established Providence Point in Issaquah, Regency at Ten Trails is newer and still actively building. Buyers who want a builder warranty and the ability to select a floor plan and finishes should focus on Regency at Ten Trails, while buyers who prefer an established, settled community with a deeper resale history may prefer Trilogy at Redmond Ridge or Providence Point.
