Maximum lot coverage is set by your borough or township, not York County. In York Township, coverage caps range from 30-40 percent of net lot area in low-density residential districts to as high as 85 percent in dense commercial districts.
Lot coverage (the share of a lot that structures may occupy) is regulated by municipal zoning ordinances in Pennsylvania under the Municipalities Planning Code, which lets ordinances determine the areas of land to be occupied by uses and structures. York County sets no coverage limit. York Township's caps vary by district: 40 percent of net lot area in its lower-density residential district, 30 percent in the estate/agricultural district, and up to 75-85 percent in its commercial and mixed-use districts. Some ordinances distinguish building coverage from total impervious coverage, and stormwater rules may further limit impervious area. Confirm the exact percentage for your zoning district with your local borough or township office.
Exceeding the lot-coverage limit is a zoning violation; the municipal Zoning Officer issues an enforcement notice, and fines can reach $500 per day under 53 P.S. §10617.2.
