Why we have building codes
Codes are sometimes viewed as all the things you can't do; however, the purpose of our adopted building and fire codes is to set minimum safety standards for construction, promote quality of life and ensure the safety of Castle Rock residents. Not only do building codes provide a standard benchmark that contractors must meet, they establish building safety and energy performance for years to come. However, building code does not regulate the aesthetics of buildings, or other HOA requirements.
The permitting process allows us to be sure that construction in Castle Rock meets the minimum standards set by building and fire code through a plan review and inspection process. If you have questions about how this process will affect your project, please email the Development Services Building Counter or call us at 720-733-3527.
