The No Knock List allows residents to opt out of door-to-door solicitation and sales. Any issues with a solicitor not following the guidelines of the Town No Knock ordinance may be reported to the Castle Rock Police non-emergency line at 303-663-6100. If possible, contact the police while the solicitor is still in your neighborhood. Please note, civic, religious, charitable or political causes are not required to register with the Town or held accountable to the No Knock ordinance requirements.
