Now with new exterior stairs!! Born in the 1860s, 23 Seneca has lived many lives-a grocery store, brothel, architect's studio, and music studio. Zoned Uptown Subdistrict B (wildly flexible), this mixed-use gem in Uptown is ready for investors, entrepreneurs, an unforgettable Airbnb, duplex, live/work space, workshop, barbershop, nail studio, or anything else you can dream of. Lovingly reimagined by Allegheny County's former chief architect, upstairs it features a sunken living room, lofted bedroom, main floor laundry, new bath, and views galore! On the ADA-accessible commercial level also contains a full bathroom and kitchenette, plus a massive basement with a bonus finished room. Use this as an apartment or commercial! Updated electric throughout, new furnace, and URA-funded structural stabilization (documentation is available). Right in the middle of the EcoInnovation District including many new, hip businesses and walking distance to downtown, UPMC, Oakland, the Hill and the South Side!
