Because of the criminal violation, even without the crime free lease addendum, you would be allowed to start the eviction process immediately under Colorado law and do not have to wait until March 1, 2013. In fact, other tenants could complain if you waited that long.

Presumptively this is a violation of your lease agreement, if so, yes you can begin eviction with a notice to quit. Being current on the rent will not allow a tenant to remain in possession of your property in violation of your lease agreement.
Be certain that you follow the correct procedure or this could significantly delay your eviction and add to your costs.
Call me if you need help.
