Visitors register after8–29 days

Colorado treats visitors as 'temporary residents' once they are present more than 14 consecutive business days or more than 30 aggregate days in a calendar year. CBI says temporary residents register within five business days of arrival with the local police or sheriff. Enrollment at a Colorado school triggers registration immediately, and local ordinances can restrict lodging after as few as five days.

Registering as a visitor

When it's required

After 14 days, counted in total over a calendar year.

Deadline

CBI states temporary residents must register within five business days of arrival in Colorado; the trigger is presence for more than 14 consecutive business days or an aggregate of more than 30 days in a calendar year. Enrollment in any Colorado educational institution triggers registration with no day threshold.

Where

Local law enforcement agency where staying - city/town police department, or county sheriff in unincorporated areas

Also required if

Employment in Colorado, paid or unpaid, beyond the same day thresholds
Enrollment in any Colorado educational institution, full- or part-time, with no day threshold
Establishing an additional residence in any Colorado city, town, or county (register within five business days)
Lacking a fixed residence does not exempt; such registrants re-register quarterly

Public registry

The law doesn't clearly say whether visitors appear on the public registry.

The CBI public website posts people convicted as adults of felony sex offenses who are currently registered, under C.R.S. 16-22-111. Misdemeanants and juveniles are not posted. Nothing exempts temporary residents, so a qualifying visitor who registers should expect to appear with their Colorado address. The site lists those 'currently registered,' implying removal once the Colorado registration is cancelled, but the mechanism and timing on departure could not be verified.

Places registrants can't go

Statewide schools, parks, playgrounds, day cares, libraries; HalloweenNo statewide presence restriction or Halloween statute was found; this rests on secondary sources and the absence of any such rule on the CBI page.Applies to: All registrants
Supervision conditionsProbation, parole, community corrections, and Sex Offender Management Board standards commonly impose no unsupervised contact with minors, no loitering where children gather, and Halloween conditions.Applies to: People under supervision
Municipal residency-exclusion zones (e.g., Northglenn, Mead, Englewood)Many municipalities impose 1,000-foot residency exclusions around parks, schools, bus stops, day cares, pools, and trails, and define 'temporary residence' as little as 5 days aggregate in a year (Northglenn) or 14 consecutive days (Mead). Police may refuse a registration listing an address that violates a local ordinance.Applies to: Registrants lodging in those municipalities, including visitors

Research notes

No official statutory text of C.R.S. 16-22-102, -103, -108, or -111 was read; all figures come from CBI's paraphrase of those statutes. '14 consecutive business days' is longer than 14 calendar days, and the 30-day aggregate counts repeat trips. The interaction between the day thresholds and CBI's 'register within five business days of arrival' instruction is ambiguous. The absence of statewide presence restrictions rests on secondary sources and could not be confirmed against official text. Municipal ordinances vary widely and were not surveyed comprehensively; the cited Northglenn, Mead, and Englewood details come from unread secondary sources. Not legal advice. [Reviewer 2026-09-19: public listing changed from long_term to unknown: the statute is silent on removing visitors, which isn't evidence that they stay listed.]
