Montaine, Castle Rock CO: Neighborhood Guide

Where Montaine is and how it connects

Montaine sits on the south side of Castle Rock, south of Crystal Valley Parkway and east of I-25, on about 848 acres the Town knew for years as The Lanterns. The land was annexed into the Town in 2002 and zoned in 2014 (Colorado Community Media, February 2019), so Montaine is inside Town limits, and its metro districts' 2026 tax records include the Town of Castle Rock levy. Homes carry Castle Rock 80104 addresses.

A loop road with two entrances connects to Plum Creek Boulevard and Old Lanterns Parkway. The bigger change is the new Crystal Valley interchange: the northbound I-25 ramps at Exit 179 opened on July 2, 2026, and the southbound ramps are scheduled for 2027 (Town of Castle Rock). Until then, the drive home from the north still runs through the Plum Creek Parkway exit. My Crystal Valley interchange guide covers what that means day to day.

Approximate drive distances from Montaine, based on OpenStreetMap routing checked in October 2026:

• Downtown Castle Rock about 5 miles
• Denver Tech Center (Belleview Avenue) about 23 miles
• Downtown Denver about 33 miles
• Colorado Springs about 40 miles
• Denver International Airport about 50 miles

The homes and builders in Montaine

Montaine is Toll Brothers' community. Toll Southwest LLC builds the public improvements: Phase 1 started in October 2019 and Phase VI was finished in spring 2025, according to the Lanterns districts' 2025 annual report. The approved site plan allows up to 1,200 single-family detached homes, 664 of them age-restricted (Colorado Community Media, February 2019). The community site advertises homes from the low $600,000s and lists 10 model homes: six at Regency, three for Toll Brothers' all-ages homes and one for DRB Homes (livemontaine.com, October 2026).

You can bring your own agent to the model home on your very first visit. Builders handle registration differently, so check each builder's registration policy before you walk in. Here is why that first visit matters when you're buying new construction in Colorado.

There are two neighborhoods, each with its own amenity center. What is selling as of October 2026:

• Regency at Montaine (55+) Toll Brothers' age-qualified neighborhood, in the Jefferson, Broomfield and Boulder Collections, with plans from about 1,601 to 3,071 square feet priced from $649,995 (tollbrothers.com, checked October 13, 2026). Ask the HOA for its age-verification and occupancy rules.
• Toll Brothers all-ages homes The Overlook Collection from $769,995 and the Estate Collection from $926,995, single- and two-story plans from about 2,567 to 4,314 square feet across the all-ages neighborhood (tollbrothers.com, checked October 13, 2026).
• DRB Homes Also building in the all-ages neighborhood. DRB Homes is the former Brightland Homes (earlier Wonderland Homes), the builder line that opened Montaine models in October 2020; Brightland consolidated under DRB Group in 2025. Jome lists DRB's Montaine homes from $744,400, 2,450 to 4,733 square feet (checked October 13, 2026).

HOA, metro district and carrying costs

Each neighborhood has its own HOA. 55places lists Regency at Montaine dues at $200 to $221 a month (checked October 2026). For the all-ages neighborhood, Jome lists about $150 a month for the DRB section, managed by The Management Trust (checked October 2026). I couldn't confirm current dues from the HOA itself, so ask for the HOA's disclosure package before you write an offer.

Montaine sits in Lanterns Metropolitan District Nos. 1 through 3, which finance roads, water, sewer and other public improvements. Their 2026 disclosure notices show different levies for collection in 2026: 57.603 mills in District No. 1, 79.217 mills in No. 2 and 77.210 mills in No. 3. At the 6.25% residential assessment rate HB24B-1001 set for local government levies collected in 2026, that's roughly $360, $495 or $483 a year per $100,000 of assessor's value, before exemptions. The districts' 2018 boundary map shows the three as interleaved parcels across the community rather than one district per neighborhood, so check the specific lot's tax district on the title commitment or with the Douglas County Assessor.

District No. 1 refinanced its 2019 bonds in December 2024 with $29.02 million of Series 2024 bonds at 4.435%, which its financial advisor said lowers the debt service levy starting in 2026. District No. 2 issued $25.48 million in 2021 and No. 3 issued $16.74 million in 2023 (Piper Sandler debt overview, March 2025). My metro district tax comparison explains how these levies show up on a title commitment.

Amenities and what is nearby

Montaine's amenities split by neighborhood, with the open space shared. From the builder, community and news sources noted (checked October 2026):

• Open space and trails 548 acres of open space and 13 miles of trails (tollbrothers.com). The 2019 site plan set aside nearly 550 acres, about 65% of the land, as public open space with a link to the Front Range Trail.
• All-ages clubhouse Pool and water play area, fitness center and playground (tollbrothers.com, October 2026).
• Regency clubhouse Lap and lounge pool, spa, fitness center, pickleball and bocce ball courts and a tennis court (tollbrothers.com, October 2026).
• History on the land The plan preserved a historic gravesite and silo (Colorado Community Media, February 2019). Trails lead to the top of Mount Montaine, which Toll Brothers and the 2019 coverage both describe as the highest point in Castle Rock.
• Nearby Downtown Castle Rock is about 5 miles north, and Toll Brothers points to Philip S. Miller Park as a nearby draw.

What to check when buying in Montaine

My free buyer's guide has the full checklist. For foundations, my soils report guide explains the engineering terms, and my Castle Rock water guide covers the Town's supply and rates. At Montaine, these items deserve extra time:

• Which Lanterns district Levies run from 57.603 to 79.217 mills depending on the district, and the district boundaries cut across neighborhoods, which works out to about $135 a year per $100,000 of assessor's value, or roughly $1,000 to $1,500 a year at typical Montaine values. Check the lot's tax district before you choose.
• Water Efficiency Plan Montaine homes come with a fixed water budget under the community's Water Efficiency Plan, and changing builder-installed fixtures or landscaping can raise your Castle Rock Water bill (Toll Brothers homeowner packet, 2020).
• Soils and foundation Ask for the lot's soils report and engineered foundation design.
• Builder warranty and contract Get the warranty in writing, including the structural term, and have the builder's purchase contract reviewed before you sign.
• Lot premiums View and open-space lots usually carry a premium. Get the number in writing.
• Radon Ask whether a passive mitigation system was installed, and test after you move in.
• Interchange timing Southbound ramps at Exit 179 aren't scheduled until 2027, so test the evening drive home before you buy.

Selling a home in Montaine

Selling a resale in Montaine means competing with Toll Brothers' own inventory, and Toll's Montaine and Regency pages advertised an $85,000 flexible incentive in October 2026. Buyers will ask why they should pay close to new-home prices for a home that's already been lived in.

Your answers are the things a new build doesn't come with: finished landscaping that already meets the water plan, window coverings, a settled lot and a closing date measured in weeks, not months. Price against closed resales rather than builder list prices, and start with a free home value estimate.
