Rarely available legal nonconforming two-flat in the heart of Northfield-119 Happ Road presents a versatile opportunity for investors, multi-generational living, or income-seeking buyers. Situated on a deep 15,166 sq ft lot, this two-story brick and aluminum sided home features two full living units, each with its own kitchen, living and dining areas, and private bedrooms. The first floor offers some updates, while the second unit requires more extensive renovation, making the property well-suited for restoration or redevelopment, depending on buyer goals. Though zoned R-4 single family, the home may continue to operate as a two-flat, provided no structural changes are made and its use remains uninterrupted. The lot's depth and favorable setbacks also allow for future expansion as a single-family residence or the potential for a custom new build. Ideally located within walking distance to Clarkson Park, Mariano's, the public library, and Northfield's Town Center, the property also offers excellent access to I-94, nearby forest preserves, and North Shore trails. Located in top-ranked Avoca District 37 and New Trier High School district 203, this listing offers rare flexibility in one of the North Shore's most desirable communities. The property is also being marketed as a land sale. Please contact the listing agent for further information and full zoning and use details. 123 Happ Road to the north is also available as both a 2-4 unit and land. Please do not walk the lot without a confirmed appointment.
