Lancaster County sets no lot-coverage limit. Municipalities do, under MPC §603(b), which authorizes zoning of the “areas and dimensions of land… to be occupied by… structures.” Caps vary by district — Lancaster City allows up to 85% lot coverage in some districts. Check your municipal ordinance.
Maximum lot (or impervious) coverage — the share of a lot that buildings and paving may cover — is a municipal zoning standard, not a county rule. MPC §603(b) authorizes municipalities to regulate the “areas and dimensions of land… to be occupied by uses and structures.” Lancaster City's Chapter 300 sets coverage by district (for example, up to 70% building coverage and 85% lot coverage in denser districts), while lower-density townships allow much less. Coverage limits interact with stormwater rules enforced by the Lancaster County Conservation District. Because the figure depends on your specific district among the county's 60 municipalities, confirm it in your local zoning ordinance's dimensional table.
Exceeding the coverage limit is a municipal zoning violation — permit denial and fines — and can also trigger stormwater-management requirements before any additional impervious area is approved.
