How long does a landlord have to return a security deposit in Colorado?

In Colorado, the deadline is 30 days (or per lease, up to 60 days). That clock runs from move-out and the return of possession, not from the end of the lease.

Colorado law sets the maximum deposit at 2 months' rent (effective August 7, 2023).

Missing the deadline has teeth. Across states, remedies range from losing the right to any deduction to penalty damages plus the tenant's attorney's fees. The itemized deduction statement has to arrive inside the same window to preserve any deduction at all.
