Building in central Douglas County
Building where water shapes the rules.
Colorado Custom Home Builder plans and builds custom homes in Castle Rock and the surrounding Douglas County communities. Castle Rock has put unusual effort into its long-term water supply, and that shows up in how new homes are landscaped and what they pay when the permit is filed.
- Permits
- The Town of Castle Rock's Building Division reviews and permits homes inside town, with applications filed online. Unincorporated lots go through Douglas County.
- Water fees
- Castle Rock Water charges renewable water and system development fees when a complete permit application is submitted. Since June 2026 those fees are tied to a home's floor area.
- Landscaping
- The town adopted water-wise landscaping rules for new homes in 2022, and homes built under them use noticeably less water.
Local conditions
What shapes a custom home in Castle Rock.
Landscape as part of the design
Under the town's landscaping rules, turf areas and plantings are planned with the house. Treating landscape as a design element from the start avoids redesign at permit time.
Size and fees go together
With water fees tied to floor area, square footage carries a direct cost at permit time. It's worth knowing the fee schedule while the floor plan is still flexible.
Buttes, bluffs and views
Rimrock and mesa edges give Castle Rock its views, and they bring slope, exposure and sometimes rock near the surface into the foundation design.
The Palmer Divide to the south
South of town toward Larkspur and Perry Park, the land climbs onto the Palmer Divide, where snow and wind are heavier than in the town itself.
