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 clinical suite: two treatment rooms, private office, conference area, kitchen, and an in-suite bathroom, with plumbing in the walls.

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.
