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.
Specifications
Home Stock
Wikipedia documents the housing stock as consisting largely of late 19th-century and early-to-mid 20th-century structures, including Victorian-era single-family frame homes and brick duplex twins. The 2009 Inquirer article describes ‘apartments, twins, and single homes set close to the street on small lots with deep backyards.’ The average year built of 1937 (public records, 33-year index) aligns with this Early-to-Mid 20th-century pattern.
Location & Access
Lancaster Avenue (US Route 30) forms the northern boundary; Conestoga Road is the central arterial; community is roughly bounded by Lewis Lane, Garrett Avenue, and Lowrys Lane. The SEPTA Norristown High Speed Line (M line) Garrett Hill Station sits between Garrett Avenue and Lowrys Lane, one block south of Lancaster Avenue.

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.

Worth Asking
Have you considered that Garrett Hill’s Radnor Township student-rental ordinance — which limits single-family rentals to no more than two unrelated students per unit and requires township approval as a ‘student home’ — could directly affect how an investor property performs, and that properties on Conestoga Road have already changed hands with tenant displacement reported as recently as 2023?
Common Questions
What schools serve Garrett Hill, and how is the district rated?
Garrett Hill falls within the Radnor Township School District, with Radnor Elementary as the most common feeder school at the elementary level, followed by Radnor Middle School and Radnor High School. The district serves nearly 3,600 students across five schools and has been ranked the #1 school district in Pennsylvania by Newsweek (2021). Buyers should confirm current elementary attendance zones with the district before contract, as boundaries are subject to change.
Is there a homeowners association in Garrett Hill?
No HOA has been identified in public records for Garrett Hill. The community is an unincorporated area of Radnor Township, and maintenance of common interests has historically been addressed through civic organizations — principally the Garrett Hill Coalition — and through the township’s Garrett Hill Overlay District zoning code, adopted in 2009. Buyers purchasing for investment should review the township’s student-rental ordinance, which functions as a land-use control even in the absence of a private HOA.
What is the transit access like from Garrett Hill?
Garrett Hill has its own dedicated station on SEPTA’s M line (formerly the Norristown High Speed Line), located at Lowerys Lane and Fairfax Road in the center of the community. The line runs between 69th Street Transit Center in Upper Darby and Norristown Transportation Center, with service in both directions. Villanova University’s off-campus housing guidance lists the Garrett Hill stop as a primary transit option for students, which contributes to the rental demand that defines part of the community’s residential mix.
