Kentucky Garage Conversions Law: Statewide Accessory Structures Rules (2026)

Key Facts

Code basis: Kentucky Residential Code
Statute: KRS Chapter 198B
Egress windows: Required sleeping rooms
Ceiling minimum: 7 feet habitable

Full Breakdown

Converting a garage to habitable living space in Kentucky requires building permits and full compliance with the Kentucky Residential Code under KRS Chapter 198B. The state code, adopted statewide, mandates minimum ceiling heights of 7 feet, egress windows in sleeping rooms, smoke and carbon monoxide alarms, insulation meeting Kentucky Energy Code, and proper heating and ventilation. The fire-rated separation between garage and dwelling under IRC R302.6 must be addressed when removing garage classification. Local building officials enforce state standards but cannot lower them. Local zoning may impose additional limits on parking, lot coverage, and minimum dwelling area independent of code compliance.

Violations & Penalties

Unpermitted conversions trigger stop-work orders, daily fines, and required certificate of occupancy with possible reversal to garage use if non-conforming.
