Millcreek, PA Building Setbacks & Zoning: Setback Rules (2026)

Setbacks in Millcreek Township are set in the Dimensional Standards table of each zoning district in Chapter 145, Zoning. In the four residential districts the printed minimums are: CR Conservation Residential (§ 145-14) 30 feet front, 40 feet rear, 7 feet side; R1 Single-Family Residential (§ 145-15) 25 feet front when the front facade faces a collector or higher classification Street and 15 feet when it faces any other Street classification, 30 feet rear, 7 feet side; R2 Low-Density Residential (§ 145-16) 25 feet front, 30 feet rear, 7 feet side; and R3 Moderate-Density Residential (§ 145-17) 25 feet front, 30 feet rear, 30 feet side. The C1 Corridor Commercial table (§ 145-18) prints 10 feet front, 20 feet rear and 10 feet side.

The § 145-11 definition of SETBACK ties the rule to Buildings. Structures as to which Chapter 145 does not impose setbacks include fences, landscape features, playground equipment, HVAC units, driveways, sidewalks, basketball hoops, concrete, paved and like pads at grade and at-grade Patios.

Section 145-26 adds the special cases. On a Corner Lot every frontage must meet the minimum Front Yard Setback, and in a Residential Zoning District the sum of the required Rear and Side Yard Setback distances can be allocated between them, but the Side Yard can never be less than the required minimum Side Yard Setback. Sills, Eaves, belt courses, cornices and ornamental features not wider than 18 inches can project into required yards, as can chimneys and flues not exceeding 3 1/2 feet in width. No Motor Vehicle parking is allowed between the Building and the Right-of-Way line.

Section 145-27 covers accessory buildings. In a Residential Zoning District an Accessory Structure can sit two feet from the Lot's boundary line if it is at least 10 feet to the rear of a Dwelling and at least five feet from an attached porch, Patio or deck. Within 10 feet of a Principal Structure it counts as attached and meets every required Setback. An Open Porch can extend in a Front Yard not more than 10 feet beyond the required Setback.
