Summary
Rock Hill defines lot coverage as the share of a lot covered by the house, accessory structures, and all impervious surfaces, pools, driveways, parking, sidewalks, concrete, asphalt or gravel, and caps it by zoning district. In the SF-3 (Single-Family 3) district, single-family detached lots may cover no more than 70% of the site, per Zoning Ordinance Sections 6.4.9 and 6.6.1.
6.4.9 LOT COVERAGE: Lot coverage represents the portion of a site that is covered by the principal use; accessory structures; and all impervious surfaces, including but not limited to pools, parking areas, driveways, streets, sidewalks, areas of concrete, asphalt, gravel or other compacted aggregate, and areas covered by the outdoor storage of goods or materials that do not absorb water...TABLE OF DIMENSIONAL STANDARDS FOR RESIDENTIAL DISTRICTS...USE MIN.

Full Breakdown
1. In the SF-3 district, single-family detached lots are capped at 70% maximum lot coverage on a minimum 14,000-square-foot lot; non-residential uses in the same district get a higher 75% cap. The pattern holds across the ordinance's single-family districts: the Rural Residential (RR) district caps coverage at 50% on its large-lot single-family tier, while SF-2 and SF-4 also list a 70% residential / 75% non-residential split in their own table rows. Because the definition sweeps in pools, driveways, patios and outdoor storage areas along with the house and any shed or detached garage, homeowners adding a pool deck or expanding a driveway can hit the district cap even without enlarging the house itself.
The Zoning Ordinance does not set a citywide flat percentage; the applicable number always depends on which residential district (RR, SF-2 through SF-5, or another district) the lot sits in.
Violations & Fines
A lot that exceeds its district's maximum coverage can be issued a correction notice and Notice of Violation by the Planning & Development Director, escalating to a municipal-court citation under Section 11.4.1 with fines up to $500 per day plus court costs and up to 30 days in jail. The City can also withhold a certificate of occupancy under Section 11.4.6 or order excess impervious construction removed under Section 11.4.7.
