Medical Office Space for Lease in Gurnee, IL: What's Available and What to Look For

If you've been searching for medical office space in Gurnee, you've probably noticed something: there isn't much of it. Generic office space comes and goes on the listing sites, but suites with real clinical infrastructure — plumbed exam rooms, sinks, a reception-to-treatment patient flow — rarely reach the market, and when they do they tend to lease quickly. This guide covers how to evaluate what's out there, what a true medical build-out is worth, and what's available in Gurnee right now.

Why medical space is different from office space

Any office can hold desks. A medical practice needs infrastructure that lives inside the walls: water supply and drain lines to every exam or treatment room, adequate electrical capacity, and a floor plan that moves patients from a waiting area through reception to private treatment rooms. Adding that to a standard office suite is a construction project measured in months and six figures — which is why the single most important question about any "medical" listing is: how much of the clinical build-out is already there?

What to check on a tour

• Plumbing in the treatment rooms. Sinks in every exam room, or capped supply and drain lines ready to reconnect, are the expensive part of any medical build-out. If they exist, you save the largest single line item in the project.
• Room count and sizes.Exam rooms typically want 90–120 square feet; treatment-room-heavy layouts (orthodontics, therapy, aesthetics) plan more space per room once circulation is counted. Count the rooms you can use as-is versus what you'd reframe.
• Patient flow.A workable layout has a waiting area facing reception, treatment rooms off a corridor, and ideally a separate staff entrance so employees and deliveries don't cross the waiting room.
• Parking and access. Suburban patients drive. Look for ample surface parking close to the entrance, and first-floor space (or elevator access) for older patients and anyone with mobility needs.
• Lease structure. A gross lease (one number that includes taxes, insurance, and common-area costs — often with electric billed separately) is simpler to budget than a triple-net (NNN) lease, where those costs float on top of base rent and can change year to year.
• Neighboring tenants. A building that already houses medical and professional tenants signals that the landlord understands clinical users — and neighboring practices generate referral familiarity.

What a built-out suite is actually worth

Industry construction guides put plumbing-intensive clinical build-outs at roughly $175–$200+ per square foot before any equipment, with fully equipped projects commonly landing in the $300–$500 per-square-foot range. Standard exam-room space is somewhat less utility-intensive but follows the same logic. Renovating a second-generation space — one that was already a clinical office — can cost a fraction of that, because the mechanical, electrical, and plumbing systems are already in place. We break the numbers down in our guide to medical build-out costs. The short version: a move-in-ready suite can save a new practice hundreds of thousands of dollars and six months or more of rent paid on a space that can't yet see patients.

The Gurnee healthcare landscape

Gurnee sits in the middle of Lake County's hospital network — Advocate Condell Medical Center in Libertyville to the south, Vista Medical Center East in Waukegan to the east, and Northwestern Medicine Lake Forest Hospital to the southeast — while day-to-day outpatient care is delivered by independent practices in exactly this kind of professional building. The village anchors a large retail-and-services corridor along Grand Avenue (Route 132) with direct I-94 access, drawing patients from well beyond its own borders.

Medical space available in Gurnee right now

Viking Square, at 4343 Old Grand Avenue, currently has three clinical suites available — all first-floor, all freshly remodeled, all on simple gross-plus-electric leases:

• A 2,616 SF medical suite: seven exam rooms, each with a sink, plus reception, a large waiting room, a private restroom, and a kitchen/meeting room. Formerly a long-standing physician practice.
• A 1,245 SF turnkey clinical suite: three plumbed treatment rooms, a lab/sterilization room, and a private office with its own entrance. Every room is plumbed, with lines capped and ready to reconnect — a strong fit for orthodontics, therapy, aesthetics, or specialty medicine.
• A 1,188 SF office suite: reception with a sliding glass window, three private offices, a conference area, a kitchen, and an in-suite bathroom.

Each listing includes an exact floor plan, specs, and an inquiry form. If you're comparing spaces anywhere in Gurnee or Lake County, the checklist above applies equally — and if you'd like to walk a truly built-out suite to calibrate what "move-in ready" looks like, schedule a tour.
