RM-5 lot near the United Center/West Loop-excellent small-multifamily infill. Steps to CTA, I-290, Medical District, and West Loop jobs/amenities. RM-5 allows multi-unit residential (two-flats, townhomes, apartments) at a higher density than RT-4, giving buyers more flexibility on unit mix and layouts (buyer to verify plans with the City). Narrow-lot reality applies, so the most practical path is a smart 2-unit design, with any higher count subject to design/relief. Strong location fundamentals and pricing aligned to lot width make this a compelling near-downtown build.
