(3) The landlord shall then have seventy-two hours excluding a Saturday,
Sunday, or a legal holiday after the actual receipt of the written notice of the
hazardous condition to have the hazardous condition repaired by a professional.
Professional for the purposes of this section means a person authorized by the
state of Colorado or by a county or municipal government through license or
certificate where such government authorization is required. Where no person with
such government authorization is available, and where there are no local
requirements for government authorization, a person who is otherwise qualified and
who possesses insurance with a minimum of one hundred thousand dollars public
liability and property damage coverage shall be deemed a professional for
purposes of this section. Proof of such repairs shall be forwarded to the landlord or
the landlord's agent. Such proof may also be used as an affirmative defense in any
action to recover the security deposit, as provided for in this section.
