Summary

Louisville Metro Land Development Code (LDC) Ch. 5 establishes minimum setbacks by form district. R-4 single-family requires ~25 ft front, 5-8 ft side, 25 ft rear. Traditional neighborhood districts allow reduced setbacks.

Full Breakdown

Louisville Metro LDC (enacted 2003 post-merger under KRS Ch. 67C consolidated government) regulates setbacks through the Cornerstone 2020 form district system instead of traditional Euclidean zoning. LDC §5.2 sets residential setbacks: R-4 (single-family) requires ~25 ft front yard, 5 ft side yard (8 ft aggregate), and 25 ft rear; R-5/R-5A reduces front to ~20 ft. Traditional Neighborhood (TN) and Traditional Marketplace (TM) form districts use build-to lines matching neighboring structures rather than fixed setbacks. Corner lots have two front yards. Small cities within Metro (St. Matthews, Anchorage, Jeffersontown, Shively, Prospect, Middletown) may have their own zoning codes under KRS Ch. 100. Variances require Board of Zoning Adjustment (BOZA) hearing. Floodplain lots near the Ohio River have additional MSD requirements.

Violations & Fines

Construction within required setback triggers stop-work order from Louisville Metro Codes & Regulations. Civil penalties $100-$1,000 per LDC §11. Structure may require removal or variance. Certificate of Occupancy withheld until compliance.
