Find out what your land is zoned for first, to determine what kind of house you are allowed to build, if any. You can call 303-679-2436 to find this out, or use our GIS ClearMap and use the Zoning Layer. Once you've established you are able to build a residence in your zoning, hire an engineer to construct Grading, Excavation, and Erosion Control plans for your parcel (we do not make recommendations for engineers). Then, submit your plans, and application documents to the Site Development Department. Contact Excel Energy for electric if needed, and the State of Colorado to obtain a Well Permit if needed. You will also need a Leach Field if you are not in an area with sanitation (which very few areas are). Contact Environmental Health for information on septic permits if needed.
