Marion County's Land Development Code controls residential lot intensity primarily through density and lot-size limits in Sec. 4.2.6 rather than a percentage lot-coverage cap. R-1 zoning is capped at 1 dwelling unit per acre, with a minimum 10,000 sq ft lot (7,500 sf with central water/sewer) and a minimum 85 ft lot width.
Unincorporated Marion County zoning under Article 4 of the LDC uses a tiered lot/utility framework: lots served by central water and sewer get smaller minimums and reduced setbacks, while lots on well/septic must meet larger minimums and deeper setbacks. R-1 lots have a 40-foot maximum building height. Accessory structures count toward usable lot area but the county does not publish a single 'maximum lot coverage' percentage for R-1; instead, build-out is constrained by the combination of setbacks (25/8/25 ft), height limit (40 ft), and density cap (1 du/acre). Higher-density residential classifications (R-2, R-3, R-4) have their own thresholds in Table 4.2-4. Cross-Florida Greenway adjacent lots have an additional 50-ft setback that further reduces buildable area.
Exceeding density caps or building outside the buildable envelope created by setbacks and height limits is a Land Development Code violation enforced by Marion County Code Enforcement and Growth Services. Variances must go before the Board of Adjustment.
