Millcreek, PA Building Setbacks & Zoning: Lot Coverage Limits (2026)

Section 145-11 of the Millcreek Township Code defines LOT COVERAGE as the area of a Lot or parcel that is covered by Principal and/or Accessory Buildings. The cap is set district by district in the Dimensional Standards table that closes each zoning district section of Chapter 145, Zoning.

In the four residential districts the Maximum lot coverage row prints 25% in the CR Conservation Residential District (§ 145-14), 32% in the R1 Single-Family Residential District (§ 145-15), 32% in the R2 Low-Density Residential District (§ 145-16) and 40% in the R3 Moderate-Density Residential District (§ 145-17). The commercial, mixed use, industrial and Presque Isle Gateway districts in §§ 145-18 through 145-25 each carry their own Maximum lot coverage row, and the C1 Corridor Commercial table in § 145-18 prints 60%.

The coverage cap sits beside the lot size rows in the same tables. Minimum lot size is 15,000 square feet in CR, 7,200 square feet in R1, 5,000 square feet in R2 and 12,000 square feet in R3. Section 145-26 A raises the minimum Lot Area to 20,000 square feet in any district where both water supply and sewage disposal are provided on the Lot, so a lot on private water and sewer starts from a larger parcel.

Because the definition counts Accessory Buildings, a detached garage or similar building counts alongside the house. Section 145-27 F requires a Permit for all Accessory Structures except one-story detached Accessory Structures with a Gross Floor Area that does not exceed 100 square feet, and even exempt structures must comply with the Stormwater Management Ordinance (Chapter 116) and the Floodplain Ordinance. Section 145-27 E allows no more than two Accessory Structures of 100 square feet of Gross Floor Area or less on a residential Lot.
