About
Garrett Hill is an unincorporated community in Radnor Township, Delaware County, approximately eight miles northwest of Philadelphia, with settlement origins traced to Welsh Quaker land grants of 1682. Its residential fabric — Victorian-era single-family frames, brick duplexes, and mid-20th-century infill — developed around a now-defunct stone quarry and brickyard that gave the area its current name. The community has its own dedicated SEPTA Metro (M line) station at Lowerys Lane and Fairfax Road, providing direct rail access to 69th Street Terminal in Upper Darby, and sits adjacent to Villanova University, a proximity that has driven recurring resident-led zoning advocacy through the Garrett Hill Coalition, which was formally organized in October 2007 to direct the township’s Garrett Hill Master Plan and Overlay District process.

What Makes This Distinct
Radnor Township adopted a dedicated Garrett Hill Overlay District zoning code — codifying front yard setbacks, prohibiting flat and hip roofs, and capping third-story habitable square footage at 60% of the second story — specifically to preserve the small-scale single-family residential character against redevelopment pressure, a legally binding land-use constraint any buyer or investor should verify before purchasing.
