Property Highlights: Versatile Duplex Layout: Separate units on the first and second floors. Premium West End Corridor: High-demand area with strong historical appreciation. Zoning Potential: CD4-L2 district offers various development or conversion paths. Rare amenities: Enjoy a spacious, fenced-in backyard and the incredible convenience of TWO separate driveways providing rare off-street parking for both units.

Bring your contractor, your architect, and your vision. 413 Islington St is ready for its next chapter. Sold “as-is.”
