Rare opportunity to acquire a shovel-ready, permit-in-hand infill package in prime Roxborough/Manayunk (19128). Offered at $500,000, this sale includes two fully entitled buildable lots at 4487 Boone St and 4489 Boone St with ACTIVE and TRANSFERABLE zoning and building permits in place for two (2) three-story semi-detached single-family homes with pilot houses and roof decks. This is not raw land - months of entitlement work and risk have already been completed, allowing a buyer to move directly into mobilization and construction. Both lots have issued building permits, including RP-2025-011951 (4487) and RP-2025-012004 (4489), issued 12/16/2025. The project includes approved architectural and structural plans, and a complete diligence binder is available upon request. A tax abatement application has been submitted and receipt has been confirmed by the Office of Property Assessment, with approval and schedule subject to City review. In addition to being fully permitted for the two-home semi-detached build, 4489 Boone offers dual-frontage / through-block characteristics that may provide future subdivision upside (for example, the ability to create an additional lot with separate frontage), subject to City approvals and buyer due diligence. This optionality is intended to be marketed as potential only and is not represented as an existing entitlement. Off-street parking is accommodated on-site, and the package is ideally suited for a builder or developer seeking a de-risked, permit-in-hand start in one of Northwest Philadelphia’s most desirable infill submarkets.
