A renovation permit has been issued for a residential development at 919 W. Sheridan in Chicago. Planned by Base 3 Development, the project will retain the existing 122-year-old three-story building on the site and incorporate it into the development, adding a four-story rear addition and redesigning the unit layouts to increase the total unit count from three to 12.

Why it matters

This project is an example of how developers in Chicago are working to preserve historic buildings while also increasing housing density in the city. The adaptive reuse approach helps maintain the character of the neighborhood while providing more living units.

The details

The project, designed by Gansari & Associates, will rehab the existing three-story building and add a four-story rear addition with a fourth-floor addition on top of the existing building. The unit mix will include 3 one-beds, 7 two-beds, and 2 three-beds, with all units having private decks and accessing a shared outdoor deck and staircase. The project received zoning variances to reduce the rear and side yard setbacks.

  • The ZBA approved the zoning variances in December 2025.
  • The renovation permit was issued on April 1, 2026.
