Hyperbaric chambers in Illinois
Illinois pairs an active Office of the State Fire Marshal with the City of Chicago's own stringent building department, making the Chicago metro one of the more closely reviewed areas in the Midwest. Downstate, county and municipal officials handle review with a lighter touch. A soft-shell wellness chamber is achievable across the state with the right documentation.

NFPA 99 & fire code in Illinois
Illinois is one of the more actively reviewed states for hyperbaric installs. Fire marshals and building officials here regularly reference NFPA 99 — the National Fire Protection Association's standard for health care facilities — when they look at a chamber, and a formal plan-review step before you energize is common, especially around Chicago, Aurora, and Naperville.
That posture is aimed primarily at oxygen-enriched, rigid medical chambers. The soft (Class C) chambers Metisine supplies are fabric, low-pressure (~1.3 ATA) general-wellness products rather than medical devices, so much of the conversation with your AHJ is documenting that distinction up front. Going in with a complete submittal — manufacturer specs, a ventilation/ambient-oxygen calculation, and an emergency procedure — is the difference between a smooth review and a stalled one.

Working with your AHJ in Illinois
The Authority Having Jurisdiction is whoever signs off on construction and life-safety in your area — usually the local fire marshal, building department, or both. In Illinois that's set locally, so the office serving Chicago, Aurora, and Naperville may run a different process than a neighboring county. Start by calling them and asking a simple question: "What do you require to install a fabric, low-pressure hyperbaric wellness chamber?"
Whatever the answer, three things make the review go faster: the manufacturer's specification sheet and UL/listing information for the chamber and its oxygen concentrator; a ventilation and ambient-oxygen calculation showing the room stays below the 23.5% oxygen threshold; and a short emergency procedure covering oxygen monitoring, fire-source control, and egress. Metisine's AHJ packet tool assembles all of this into a single submittal you can hand to your Illinois reviewer.
Chicago and the Illinois State Fire Marshal
The City of Chicago administers its own building code and runs a demanding permitting process, so a chamber install there should be planned with formal review in mind. Suburban Cook County and the collar counties each have their own departments as well.
The Office of the Illinois State Fire Marshal sets the statewide posture your local AHJ applies. For a low-pressure fabric chamber, the submittal that answers most questions is the same everywhere: specs, a ventilation/oxygen calculation, and an emergency procedure.

Illinois hyperbaric FAQs
Is Chicago strict about hyperbaric chamber installs?
Chicago runs its own building department and a formal permitting process, so plan for a thorough review. A complete submittal is the best way to keep it moving.
What about installs in downstate Illinois?
Outside the Chicago metro, county and municipal reviews are generally lighter, though they still apply NFPA-based fire code. Confirm with your local AHJ.
