Breach of warranty of habitability - tenant's remedies(1) If there is a breach of the warranty of habitability as set forth in section 38-12-503 (2), the following provisions shall apply:(a) Upon no less than ten and no more than thirty days written notice to the landlord specifying the condition alleged to breach the warranty of habitability and giving the landlord five business days from the receipt of the written notice to remedy the breach, a tenant may terminate the rental agreement by surrendering possession of the dwelling unit.
