Eighty healthcare-related construction permits have been filed in Chicago since January, worth $53 million combined. That's 21% more permits than the 66 filed in the same window last year — and the conversion stories are the part that matters for B2B sellers.
Which Chicago Buildings Are Converting to Healthcare Facilities?
The largest healthcare permits this year aren't hospital renovations. They're buildings changing their entire purpose.
A two-story bank at 4659 S Cottage Grove Ave in Kenwood filed a $7 million permit in May to become a single-tenant medical care facility. A church at 8301 S South Shore Dr in South Shore filed a $6.8 million permit in January to become a birth center — occupancy reclassified from religious assembly to medical services. And a daycare at 355 E Grand Ave on the Near North Side filed a $3.5 million permit in May to be absorbed into the adjacent medical clinic, with the former childcare space gutted for exam rooms and treatment areas.
A bank doesn't have medical-grade HVAC. A church doesn't have plumbing for exam rooms. These are ground-up interior buildouts inside existing shells. Everything gets purchased new.
Which Hospital Systems Are Filing Construction Permits in 2026?
The major systems are filing their own permits:
- $4.95M at 2900 N Lake Shore Dr — sterile storage expansion at an existing hospital (Lake View)
- $3.5M at 1101 S Canal St — medical office buildout in a mixed-use building (Near West Side)
- $2M at 326 W 64th St — behavioral health unit renovation at St. Bernard Hospital (Englewood)
- $1.5M at 5140 N California Ave — GI suite expansion at an existing hospital (Lincoln Square)
- $850K at 5758 S Maryland Ave — University of Chicago medical suite (Hyde Park)
- $750K at 259 E Erie St — infusion clinic renovation (Near North Side)
- $500K at 2211 N Oak Park Ave — imaging suite at Shriners Children's Hospital (Montclare)
A brand-new two-story medical office building is also going up at 5333 S Harlem Ave in Garfield Ridge — $4 million, 11,500 square feet of tenant-ready space near Midway Airport.
Where Is Chicago's $20M South Side Healthcare Construction Boom?
Three of the five largest healthcare permits this year are on the South and Southwest Sides. The Kenwood bank conversion ($7M), the South Shore birth center ($6.8M), and the Garfield Ridge medical office building ($4M) — plus St. Bernard's behavioral health renovation in Englewood ($2M) and the UChicago suite in Hyde Park ($850K) — total $20.6 million in healthcare construction south of Roosevelt Road. The South Side is also showing up in license data, with Austin, Belmont Cragin, and Little Village all posting strong filing numbers.
Dental offices are filling in the gaps at the smaller scale. Two buildouts — one at 557 W North Ave on the Near North Side, one at 2423 W Fullerton in Logan Square — are each converting roughly 2,100 square feet of existing commercial space into dental practices at around $500K apiece. A third dental office filed at 4345 N Lincoln Ave in North Center.
What Healthcare Construction Permits Mean for B2B Vendors
A medical buildout is one of the most vendor-intensive project types in the Construction Hot Blocks. Each of these 80 permits generates demand for specialized HVAC and air filtration, medical-grade plumbing, electrical upgrades, ADA compliance work, custom cabinetry, security systems, commercial cleaning contracts, signage, and IT infrastructure.
The conversion projects are the highest-value leads. When a bank becomes a clinic, there's no prior medical vendor to displace — the operator is buying everything from scratch, on a timeline the permit data reveals months before the doors open. Many of these addresses are also filing new business licenses — the intersection of permit + license activity is the strongest buying signal in the dataset.
