Read and acknowledge the disclaimer at the bottom of this section.

Pursuant to 16-22-112(2), Colorado Revised Statutes, a local law enforcement agency is authorized to post on its website sex offender registration information of a person from its registration list.
The Colorado sex offender registry includes only those persons who have been required by law to register and who are in compliance with the sex offender registration laws. Persons should not rely solely on the sex offender registry as a safeguard against perpetrators of sexual assault in their communities. The crime for which a person is convicted may not accurately reflect the level of risk.
The Boulder County Sheriff’s Office has not considered or assessed the specific risk that any convicted sex offender displayed on this web site will commit another offense or the nature of any future crimes that may be committed.
Only information on registered sex offenders allowed to be disclosed under Colorado law appears on this web site. Under state law, some registered sex offenders are not subject to public disclosure, so they are not included on this site. State law does not allow offenses other than the crimes for which the convicted sex offender is required to register to be disclosed here.
Extreme care must be taken in the use of information because mistaken identification may occur when relying solely upon name, birth date and address to identify individuals.
If you believe that any information on this site is in error, please contact Boulder County Sheriff’s Office, by phone at 303-441-3650
Registered sex offenders are only shown for areas within Boulder County Sheriff’s Office jurisdiction. Municipalities located within Boulder County that have their own police departments are not included on this web site.
The information on this web site may not be used to inflict retribution or additional punishment on any person convicted of unlawful sexual behavior or of another offense, the underlying factual basis of which involves unlawful sexual behavior.

I certify that I have read the above disclaimer and hereby swear and agree to these terms, uses and conditions. By clicking I agree you will be leaving the Boulder County website and will be sent to a web based sex offender tracking program powered by Douglas County Sheriff’s Office.

About Sex Offender Registration

You can fill out and print the below forms. DO NOT initial, date, and sign the forms. This will be completed at the time of your appointment.

Q. Are all of the registered sex offenders in my neighborhood on your web page?

A. Not all registered sex offenders are displayed on the web. Only offenders that have been convicted of a felony sex crime as an adult are displayed and some offenders that have met specific criteria. Offenders convicted of a misdemeanor sex crime and offenders adjudicated (juvenile conviction) as a juvenile of a sex crime are typically not displayed on the website. For a full list of sex offender you can pick it up for free at our Records Department after filling out paperwork with presentation of a valid ID.

Q. Are there restrictions on where sex offenders can live?

A. The only time that there are restrictions on where, and with who, registered sex offenders can live with, is if the offenders are on probation or parole. If a registered sex offender is not being supervised by probation or parole, then they can live wherever they want, and with who-ever they want, to include living with children in the residence.
Colorado state law does not place any restrictions on where sex offenders can live, or with whom they can live, and the County of Boulder does not have any restrictions. Some jurisdictions in the Denver metro-area do have restrictions on where sex offenders can live.

Q. Can sex offenders live on the street and not at a specific address?

A. Boulder County registers all sex offenders that call Unincorporated Boulder County “home”. If a sex offender does not have a permanent address (moving from location to location) or is homeless (living in shelters or on the streets) they can and will be registered. The sex offenders will typically be listed as “Transient”.

How to Register as a Sex Offender

Please arrive at least 5 minutes early to complete any paperwork prior to your appointment. If you are more than 10 minutes late for your appointment, you may be asked to reschedule in order to allow other scheduled appointments to continue on time.

Q. Where do I need to go to register?

A. All sex offender registrations are completed at the Boulder County Department Headquarters building, located at 5600 Flatiron Pkwy, Boulder, CO 80301.

Q. What are the hours I can come in and register?

A. The Sex Offender Registration Unit registers on Tuesday and Thursday by appointment only. You must call for an appointment at 303-441-3650 or if calling not during business hours 303-441-3611.

Q. What do I need to bring and how long will it take to register?

A. You do not need to bring anything with you other than your Driver’s License, State Identification Card, or some form of I.D. You must know the address you are registering to and have to complete a registration form. If it is not your first time registering with the Boulder County Sheriff’s Office and the office is not busy, you may be in and out of the building within 15 minutes. If it is your initial (first time) registration in with the Boulder County Sheriff’s Office, you should expect that the registration from start to finish will likely take at least one hour.

Q. How much are the registration fees and how can I pay them?

A. Registration fees are as follows:
- Initial registration fee with the Boulder County Sheriff’s Office – $75.00
- Annual Registration Fee – $25.00
- Quarterly Registration Fee – $15.00

We accept cash or credit card payment at the time of the registration appointment.

Q. How do I stop registering as a sex offender?

A. All registered sex offenders are required to register until they get a court order to discontinue registration. It doesn’t matter what you thought the plea bargain was for in your case, what your probation/parole officer, or any police office told you….there is not a set time you have to register and then you can stop. Depending on what you were convicted of, after a set amount of time you can petition the court to no longer have to register. If the court grants it and a judge issues a court order allowing you to discontinue registration, then you are no longer required to register. The amount of time you are required to register for depends on what you were convicted of. Typically juvenile convictions allow for the petition to be filed upon completion of supervision. Adult convictions require registration for either 5, 10, or 20 years, or life.

For additional information on what is needed to file a petition to no longer have to register and for the forms needed to file the petition, go to the State of Colorado Judicial Branch, and click on the correct folder that fits your conviction.
