Investment Highlights

  • Prime Sunnyside Location
  • Successful Rezoning
  • Excellent Transit Access

Executive Summary

4155 Jason Street represents a rare, multifamily development opportunity located at the intersection of 40th Avenue and Jason Street in Denver’s highly sought-after Sunnyside neighborhood. The ±0.65-acre site is zoned U-RX-5, supporting high-density residential and mixed-use development.


The site benefits from a highly central location with direct connectivity to Downtown Denver, LoHi, Highland Square, and RiNo, all of which continue to drive residential demand and capital investment. The property is also located in close proximity to the Fox Park redevelopment area, an emerging mixed-use district expected to further enhance neighborhood amenities and long-term tenant appeal. Regional access is provided by close proximity to I-70 and I-25, while transit connectivity includes nearby RTD bus service along 38th Avenue and Federal Boulevard, convenient access to 41st & Fox Station, and Union Station, Denver’s primary multimodal transit hub offering light rail, commuter rail, and regional bus service.

Sunnyside has emerged as one of Denver’s most desirable neighborhoods, driven by its walkability, proximity to employment centers, adjacency to established and emerging lifestyle districts, and limited availability of entitled development sites. The U-RX-5 zoning allows for a dense, urban-scale residential project consistent with the neighborhood’s ongoing evolution, supporting a variety of multifamily or mixed-use residential concepts designed to capture sustained renter demand.

With zoning approvals in place, a central infill location at 40th & Jason, and strong long-term market fundamentals, 4155 Jason Street offers developers an opportunity to deliver new housing in a proven infill submarket with constrained land availability.
