Certain sex crime convictions require you to register as a Colorado sex offender. Depending on your case, your information may be publicly searchable on Colorado’s Sex Offender Tracking and Registration System (“SOTAR”).
You are required to re-register once a year and whenever you change addresses. Though if you are classified as a sexually violent predator (SVP), you must re-register every three months. Failing to register is a felony carrying up to one and a half years in Colorado State Prison.
If you avoid further sex crime convictions, you may be eligible to get removed from the registry after a minimum time period following the completion of your sentence (including probation and parole). The wait depends on your underlying conviction:
- Certain class 1, 2, and 3 felonies: After 20 years.
- Certain class 4, 5, and 6 felonies: After 10 years.
- Class 1 misdemeanor sexual assault or sexual contact: After 10 years.
- Other misdemeanors: After 5 years.
Note you may not petition to get off the registry if you are an SVP, or you were convicted of felony sexual assault or felony incest, or you were convicted of at least two convictions of unlawful sexual behavior.

Note that you still must register in Colorado if you were convicted of a similar crime in another state.
If you finished serving your sex offense sentence prior to July 1, 1991, you may not have to register. Check with your attorney to learn whether you are exempt.1
Most sex offenders may be eligible to eventually get off the registry in Colorado.
2. Purpose of Registry
Colorado’s sex offender registry is a public safety and community notification service.
It allows the general public to search for convicted sex offenders living in their area. Plus law enforcement uses it to keep track of offenders in their jurisdictions. If you are a registered sex offender, the police get notified whenever:
- You fail to register or
- You re-register in another jurisdiction.
The registry also shows whether you are an SVP, short for “sexually violent predator.” SVPs are the most high-risk class of Colorado sex offenders.
The sex registry serves not only to punish offenders and help police track them but also to deter future sex offenses: Being on the sex registry carries an enormous social stigma, negatively impacts relationships, and hinders future employment prospects.
3. Information You Must Provide
If you are required to register as a sex offender in Colorado, you must provide the following information to the county sheriff’s office:
- Name (including aliases),
- Instant messaging and chat room identities,
- Registration status,
- Date of birth,
- Address,
- Place of employment,
- Physical description,
- Photograph,
- Full set of fingerprints, and
- Vehicle information.2
4. Public Information
If you are a registered sex offender in Colorado, the Colorado Bureau of Investigation website reveals the following information about you:
- Name,
- Birthday,
- Residential address (including county),
- Vehicles,
- Custody status,
- Headshot,
- Gender,
- Race,
- Height,
- Weight,
- Hair color,
- Eye color,
- Scars, marks, and tattoos,
- Crimes and conviction dates,
- Whether you are a sexually violent predator,
- Modus operandi information (details of predatory habits), if known, and
- Whether you ever failed to register as a sex offender.
The local police department may also post this information on their website.
Note that you are not publicly searchable on the registry if you were:
- Adjudicated as a juvenile or
- Convicted only of a misdemeanor.3
One of the goals of the sex offender registry is to prevent recidivism.
5. Registration Requirements
If you are required to register as a sex offender in Colorado, you usually must update your information annually within five business days of your birthday. However, certain offenders are required to re-register every three months. (Scroll down to the next section for more information about these “quarterly offenses”.)
In addition, you must re-register whenever you:
- Change an address; or
- Add an address; or
- Move your trailer or motor home (if applicable); or
- Legally change your name.
There are also rules if you attend, volunteer, or work at an institution of higher education: You must re-register when you begin your work or study. Then you must re-register anytime you change your work status or location at the institution.4
6. Quarterly Registration
You are required to register as a sex offender every three months in Colorado if you either:
- Are a sexually violent predator (SVP); or
- Were convicted out-of-state if the conviction would require quarterly registration in Colorado; or
- Were convicted as an adult in Colorado of:
- felony sexual assault; or
- sexual assault on a child; or
- sexual assault on a child by one in a position of trust; or
- sexual assault on a child by a psychotherapist; or
- incest; or
- aggravated incest.
Otherwise, you are required to register annually.5 The following table summarizes registration requirements.
| Type of Sex offender | Registration Requirement in Colorado* |
| Transients | Every 30 days |
| Sexually violent predators (SVPs) | Every 90 days |
| All other sex offenders | Once a year |
| *You must register within 5 days of being released from prison and moving homes. | |
7. Residency Restrictions
State law does not restrict where sexual offenders may live. However, many local ordinances do prohibit offenders from living near:
- schools,
- churches and places of worship,
- parks,
- daycare centers, and/or
- other places children gather.
8. Length of Registration
How long you must remain on the Colorado sex offender registry depends on what you were convicted of, as the following table shows.
| Colorado Crime Requiring Sex Offender Registration | Minimum Years You Must Register |
| Sexually violent predators (SVPs – people with a high level of risk) | For life |
| Felony sexual assault | For life |
| Sexual assault on a child | For life |
| Sexual assault on a child by one in a position of trust | For life |
| Sexual assault on a child by a psychotherapist | For life |
| Incest | For life |
| Aggravated incest | For life |
| More than one conviction of unlawful sexual behavior | For life |
| Other class 1 felonies | 20 years |
| Other class 2 felonies | 20 years |
| Other class 3 felonies | 20 years |
| Other class 4 felonies | 10 years |
| Other class 5 felonies | 10 years |
| Other class 6 felonies | 10 years |
| Class 1 misdemeanor sexual assault | 10 years |
| Class 1 misdemeanor sexual contact | 10 years |
| Other misdemeanors | 5 years |
| Deferred sentence and adjudication | Until the case is dismissed |
| You (the defendant) were under 18 at the time of the offense | Until the case is dismissed |
| Failure to register | 1 year (in addition to the required years for the underlying sex crime) |
Once you register for the minimum number of years, you may file a petition with the court seeking to get off the registry.
Note that if you are a sexually violent predator (SVP), you must remain on the Colorado sex offender registry for life.6
9. Getting Off the Registry
To be eligible for removal from the Colorado sex offender registry, you first must register for the required number of years. (See the above section for time frames.) Plus you cannot have been convicted of any other sex offenses.
Then, you need to complete a form to discontinue sex offender registration. Before filing it, you must notify:
- The law enforcement agency you are required to register with; and
- The prosecuting attorney in the jurisdiction of that law enforcement agency; and
- The prosecuting attorney who convicted you.
There is no filing fee for Colorado residents. Out-of-state residents must pay a $235 filing fee. Plus there may be fees for obtaining copies of necessary records.7
Failing to register as a sex offender is a separate Colorado crime.
10. Failure to Register
If you were convicted of a felony sex offense in Colorado, failure to register is a class 6 felony. Penalties include:
- 1 to 1 ½ years in Colorado State Prison and/or
- $1,000 to $100,000 in fines.
A second or subsequent offense is a class 5 felony. Penalties include:
- 1 to 3 years in Colorado State Prison and/or
- A fine of $1,000 to $100,000.
Failure to register is a class 1 misdemeanor if you were convicted of a misdemeanor sex offense (or its equivalent in another jurisdiction or juvenile court). The punishment is:
- Up to 364 days in jail and/or
- A fine of up to $1,000.
Convictions for failure to register will also be noted on your sex offender registry profile.8
11. Where Sex Offenders Live
To see where sex offenders live, go to the Kids Live Safe website. Users can search by zip code for nearby registered sex offenders.
12. Fighting Sex Crime Charges
Being charged with a Colorado sex crime is not a conviction. It may be possible to get the charge dismissed or reduced through a plea bargain without you ever having to register as a sex offender.
Here at Colorado Legal Defense Group, we have experience representing literally thousands of people charged with sex crimes. Depending on the specific case, the following ten defenses have proven very effective with prosecutors, judges, and juries:
- You were falsely accused.
- There was consent.
- You reasonably thought there was consent.
- The alleged victim was old enough to consent.
- No sexual contact occurred.
- No penetration occurred.
- You are a victim of mistaken identity.
- You were entrapped.
- The police found the evidence through an unlawful search.
- The police coerced your confession.
Typical evidence in these cases includes video footage, eyewitnesses, and medical records.
Misdemeanor sex offenders are not publicly searchable on the Colorado sex offender registry.
