What does my project require?
Pick where you live and what you're building. Get a plain-English checklist you can print.
1. Which building department is yours?
Not sure? Homes inside Castle Rock town limits go to the Town. Homes with a Castle Rock mailing address but outside town limits (unincorporated) go to Douglas County. Your property tax bill or the Douglas County Assessor record shows whether you're in the Town of Castle Rock tax district, or call either office and give your address.
