Talk to a Specialist →Regency at Montaine is Toll Brothers’ premier 55+ community in the Denver area — 664 planned homes in Castle Rock, Douglas County, built from 2020 to present. Priced from the $600s to over $1M+. Toll Brothers is the luxury national homebuilder; Regency is their active adult brand. The build quality, finish level, and design standard at Regency at Montaine is demonstrably higher than production-builder communities — buyers who value craftsmanship over amenity breadth choose Toll Brothers for a reason.
Castle Rock is one of Colorado’s most desirable communities — consistently ranked in the top places to live in the state. The downtown Castle Rock area, with its independent restaurants, boutique shops, and a genuine civic life, is within minutes. The Philip S. Miller Park — Castle Rock’s massive 150-acre recreation complex with a state-of-the-art gym, outdoor climbing wall, and trails — is accessible to residents.
Douglas County has an effective property tax rate of approximately 0.55% — the lowest of any county in the Denver metro area. On a $750K Regency home, annual property taxes run approximately $4,125 — about $550/year less than comparable Arapahoe County communities and $1,500/year less than comparable Jefferson County communities at higher rates. Over 20 years, the Douglas County advantage vs comparable Arapahoe County communities totals approximately $11,000.
Toll Brothers homes are not production-builder homes. The standard features at Regency at Montaine — 10-foot ceilings, engineered hardwood, quartz countertops, custom cabinetry — are upgrade options at most other builders. For buyers who have owned luxury homes and will not compromise on finish quality, Regency at Montaine is the Denver 55+ community that meets that standard.
Floor plans are designed specifically for active adult living: master-on-main, open concept, finished basements optional for guest space, and covered outdoor living areas that extend the Colorado outdoor season by months.

Buyers who want Toll Brothers quality in a 55+ setting at Douglas County’s best-in-metro tax rate, with genuine Castle Rock lifestyle access. At $600s–$1M+ this is the premium tier of the Denver active adult market. Wrong for buyers who want resort-scale social programming — Regency communities are high quality but more boutique than Hilltop at Inspiration’s 1,650-home scale.
We run the complete Douglas County cost stack and compare against every Denver-area community at your price point.
