Douglas County, with its county seat in Castle Rock, requires a site plan as part of most building permit applications. Whether you're building a new home, adding an outbuilding, or developing vacant land, you'll need to show the county where structures, wells, septic systems, and driveways will be located relative to property boundaries and setback lines.
Build Cost Check generates this site plan instantly — with real parcel data, USGS terrain contours, and automatic setback calculations. The output is a professional ARCH D (24"×36") PDF plus a DXF/CAD file that opens in AutoCAD, Civil 3D, or any drafting software.
Colorado's Division of Water Resources maintains records of every permitted well in the state. For Douglas County, Build Cost Check pulls well permit data including well depth, static water level, flow rate (GPM), and pump depth for wells near your property. This is critical information when drilling a new well or evaluating an existing one.
Our soil reports use USDA SSURGO data to show you exactly what's under your Douglas County property — soil types, percolation estimates, and septic system recommendations. Know whether a conventional septic system will work, or if you'll need an engineered system, before you commit to the land.
