Kentucky Revised Statutes Title XXXII. Ownership and Conveyance of Property § 383.635.Remedies for noncompliance that affects health and safety

(1) If the landlord willfully and materially fails to comply with the rental agreement or fails to comply with KRS 383.595 and such noncompliance materially affects health and safety and the reasonable cost of compliance is less than one hundred dollars ($100), or an amount equal to one-half (1/2) of the monthly rent, whichever amount is greater, the tenant may notify the landlord of his intention to correct the condition at the landlord's expense. If the landlord willfully fails to comply within fourteen (14) days after being notified by the tenant in writing or as promptly as conditions require in case of emergency, the tenant may cause the work to be done in a workmanlike manner and, after submitting to the landlord an itemized statement for the work actually done and for which the tenant has paid in full, deduct from his rent the actual and reasonable cost or the fair and reasonable value of the work, not exceeding the amount specified in this subsection.

(2) A tenant may not repair at the landlord's expense if the condition was caused by the deliberate or negligent act or omission of the tenant, a member of his family, or other person on the premises with his consent.
