Summary
The Zoning Ordinance defines lot coverage as the portion of a lot covered by any structure or constructed element that impedes stormwater infiltration. Rather than a fixed district percentage, buildable area is controlled through minimum lot size, setbacks, and stormwater rules.
Lot coverage: The portion of the lot covered by any structure or constructed element that impedes infiltration of stormwater into the ground or disrupts vegetated surfaces. For purposes of lot coverage standards, structures or constructed elements that allow some infiltration, such as decks, patios, and driveways, porous pavers or concrete, or other elements that disturb ground cover shall be counted towards the total surface coverage.
Full Breakdown
Simpsonville's Zoning Ordinance defines lot coverage in Section 8.3.4(B) as the portion of the lot covered by any structure or constructed element that impedes stormwater infiltration or disrupts vegetated surfaces. Decks, patios, driveways, and porous pavers count toward coverage unless shown to be an integral part of a stormwater best-management practice. The residential districts do not set a single fixed maximum coverage percentage; instead, the effective footprint is limited by minimum lot area (for example 16,000 sq. ft. in R-E), required setbacks, and stormwater management requirements. Confirm coverage and impervious-surface obligations with the Planning Department for your specific district and lot.
Violations & Fines
Coverage or impervious-surface violations are enforced through the zoning and stormwater programs, which can require corrective drainage measures or removal of noncompliant surfaces.
