Residential vacant lot in the heart of Allentown – zoned R-MH and ready for your next project. 621 N 9th St is a 20' x 115' (approx. 2, 300 sq ft) residential vacant lot with public water and sewer available, located in the City of Allentown and the Allentown School District. The R-MH zoning permits medium-high-density residential use on smaller lots, and public records indicate the land use category is “Residential under 5, 000 sq ft”. This property offers a rare infill opportunity on an established city block – close to downtown, public transportation, schools, shopping, and major roadways. Low carrying costs, with estimated 2025 taxes of about $325/year, make this an excellent build-now or buy-and-hold site. Bring your architect, builder, or manufactured-home plan and explore the possibilities.
