Prestige Contractors
Tap a star to rate
Prestige Contractors has been building in Castle Rock and Douglas County since 2001, operating for a quarter century in a market where long local roots matter. The firm does full residential construction work, including kitchens, bathrooms, additions, and custom homes, but has developed genuine expertise in accessory dwelling units, having built dozens of them across the Douglas County Front Range. What sets them apart is not a narrow single-product focus but a genuine specialization within a broader construction practice, supported by two decades of work within the specific zoning and code framework of Castle Rock and Douglas County.
Castle Rock's zoning is notoriously complex. Lot sizes, setback requirements, and ADU restrictions vary between neighborhoods and are subject to Douglas County rules that differ from Denver's or unincorporated El Paso County's. Prestige's deep familiarity with Castle Rock's zoning requirements and Douglas County's building standards reflects real accumulated knowledge. They understand which neighborhoods allow detached units, which require attached configurations, where the sight-line and parking restrictions hit you, and how to thread the permitting needle without costly redesigns. This local mastery is not trivial. An architect or contractor new to the area must invest considerable time learning local constraints through the permitting process; Prestige brings that knowledge to your first conversation.
The company offers a straightforward range of ADU types. Detached freestanding units are what most people visualize: a standalone structure in the backyard with its own utilities, parking, and entry. Garage conversions are the second major offering, typically converting an existing garage into residential space and adding a second story or side addition. They also build above-garage ADUs, where a new second-story unit sits atop a garage (new or existing), common on lots where ground-level footprint is limited. Attached living suites round out the portfolio, with a unit connected to the primary residence, useful if zoning rules restrict setbacks or if your lot is narrow. This range covers most of what Douglas County homeowners actually build.
The permitting process is where smaller builders sometimes stumble. Douglas County requires detailed site plans, utility routing, parking calculations, and setback verification, all of which must be completed before you break ground. Prestige handles full permit coordination. They manage the design package, coordinate with the county assessor and building department, and track revisions until approval. The process typically takes 6 to 12 weeks depending on county backlog and whether the design raises any flag items. Once permits are in hand, the actual construction timeline is 3 to 6 months for most ADUs, depending on size and finish complexity. This means a full project from first consultation to occupancy certificate runs roughly 4 to 8 months in most cases.
The company's building process unfolds in three phases. First comes site assessment and design planning. Prestige schedules an on-site consultation where they evaluate your lot, discuss budget and timeline, and review zoning constraints specific to your address. They then develop a design package tailored to your property and the local code requirements. The second phase is permitting and approval. This is the county coordination work, handled by Prestige's team. A 10 percent retainer secures the permitting effort, and they manage back-and-forth with the building department until final sign-off. The third phase is construction and completion. Once permits are approved, the actual build begins. Prestige provides a client project portal where you can track progress, review photos, and communicate with your project manager in real time. This transparency is a stated differentiator for them, keeping you informed about timelines and finishes throughout the build.
Prestige is a member of the National Kitchen & Bath Association and is rated "Best of the Best" by Colorado Community Media and listed as Top Rated Local. These are not guarantees, but they signal that the company has maintained consistent quality and customer satisfaction over time. They also work with local charitable organizations, which reflects a willingness to invest in community relationships beyond the immediate business. The firm's emphasis on quality materials and attention to detail is visible in their published project galleries, where finishes and site integration look genuinely thought-through.
Pricing for an ADU in the Castle Rock area typically runs $150,000 to $300,000 depending on unit size, finish level, and foundation complexity. They offer free in-home estimates and flexible financing options. For a detailed quote, you call 720-971-2397 or visit their contact page. They are clear that pricing is custom per site, not a fixed rate, because local labor costs, excavation difficulty, and material availability vary property to property.
Prestige competes against both generalist contractors and specialist ADU firms. They are not as laser-focused on a single building type as some Colorado Springs ADU-only shops, but that breadth gives them experience with the full spectrum of Douglas County residential construction, which means fewer surprises. They are also more established locally than many newer ADU specialists, with two and a half decades in the Castle Rock market and a roster of homeowners you can reference. If you want a builder who knows Douglas County zoning inside out and has built dozens of ADUs in your neighborhood, Prestige's long local tenure is a genuine asset.
The company suits homeowners who are building in Castle Rock or Douglas County and want someone who navigates the local permitting landscape without surprises. Their design-build model, where they own both the architectural planning and the construction, means no finger-pointing between designers and builders if something goes off-plan. If you are building for rental income, the project portal and regular updates let you stay informed throughout the build. If you are building for family use or just want to add value to your property, their breadth of finishing options and attention to detail in the finishes mean the result will reflect your taste, not a factory template.
Prestige Contractors represents the kind of regional contractor that thrives in markets where local knowledge is currency. They have built their reputation on understanding Castle Rock and Douglas County deeply, executing competently, and staying in business long enough that homeowners can reference their work from a decade ago. For a Douglas County ADU project, their two and a half decades of local work is a solid foundation.
