Millcreek, PA Building Setbacks & Zoning: Structure Height Limits (2026)

Section 145-11 of the Millcreek Township Code defines BUILDING HEIGHT as the distance measured from Finished Grade located within two feet of the foundation wall to the highest point on the Building or Structure, excluding elements such as chimneys, flag poles, skylights, etc. Finished Grade is the final grade of the site after all clearing and grading has been completed that conforms to an approved grading plan, so the measuring point is the graded ground at the wall, not the original slope.

The cap itself is the Maximum building height row in each district's Dimensional Standards table in Chapter 145, Zoning. It prints 35 feet in the CR Conservation Residential District (§ 145-14), the R1 Single-Family Residential District (§ 145-15) and the R2 Low-Density Residential District (§ 145-16). It prints 50 feet in the R3 Moderate-Density Residential District (§ 145-17), the district that permits Multi-Family Dwellings. The C1 Corridor Commercial table in § 145-18 prints 35 feet, and the other commercial, mixed use and industrial districts in §§ 145-19 through 145-25 each carry their own row.

Accessory buildings have a lower ceiling. Section 145-27 H provides that in all Residential and Mixed Use Zoning Districts the maximum height of all Accessory Structures on the Lot shall not exceed 20 feet. Section 145-27 I(4) adds that where a district permits a Multi-Family Dwelling, a detached garage built for the residents' Vehicles must comply with the applicable Rear and Side Yard Setbacks and height requirements for the underlying zoning district.

Section 145-27 F separately requires a Permit for every Accessory Structure other than a one-story detached one with a Gross Floor Area that does not exceed 100 square feet, and those exempt structures remain bound by the other applicable Millcreek Township laws.
