The Illinois Technology and Research Corridor Started Here

Not near here. Here.

The first companies that formed the Illinois Technology and Research Corridor began locating in Naperville in the 1960s. Northern Illinois Gas — now Nicor — moved its research and administrative facilities to Naperville in 1962. Bell Laboratories followed in 1964. The Amoco Research Center, now BP, arrived in 1969. In 1966, AT&T Indian Hill Bell Labs, later Lucent Technologies, opened an R&D facility on a 200-acre site off Naperville and Warrenville Roads with 700 employees.

That sequence created one of the four principal economic centers in suburban Chicago, alongside the I-90 Golden Corridor, the I-94 Lakeshore Corridor, and the I-55 Industrial Corridor.

Sixty years later the corridor still holds Nicor’s corporate headquarters, Nokia Bell Labs, and BP America. For an office occupier that history matters in a practical way: this is a market with six decades of experience housing corporate research, which shows up in the building stock, the labor pool, and the municipal understanding of what an R&D tenant actually needs.

And the City Says It Is Underperforming

This is the part most brokers will leave out, and it is the most useful thing on this page.

In his State of the City address in May 2026, Mayor Scott Wehrli singled out the I-88 corridor as the “largest and most significant redevelopment opportunity” in Naperville’s history. He was direct about why it matters:

“It’s no secret that I believe that the future of the I-88 corridor is the future of our city. Our transition from a quiet farm town to where the best and the brightest minds are figuring out solutions to today’s problems started in that very place.”

He was equally direct about the present. A report from the Naperville Development Partnership found much of the corridor “underperforming relative to its potential”. The city has budgeted $150,000 for a special study on either the I-88 corridor or the properties around the 5th Avenue Metra station, and a corridor branding study and marketing appointment are proceeding — in the Mayor’s words — “full speed ahead”.

The report identified target industries: agriculture and food technology and production, quantum and advanced computing, tourism, sports and hospitality.

What that means if you are taking space

Underperforming means available and negotiable. A corridor with sixty years of corporate tenancy, publicly acknowledged vacancy, and a city actively committing money to fix it is a tenant’s market right now, and the leverage is real. Rent, term, allowances, and options are all more negotiable than they will be if the repositioning works.

What it means if you are buying

Both things at once, and they should be modeled separately. The downside is genuine: underperformance is the city’s own word, and a $150,000 study is the beginning of a process rather than the end of one. The upside is that the fundamentals the Mayor cited are real and checkable — proximity, opportunity, talent, and access to Fermilab and Argonne. We underwrite the as-is income and treat the repositioning as separate upside, because an adopted intention is not an executed plan.

What Is the Naperville Workforce Like?

It is the deepest educated labor pool in the western suburbs, and for an office occupier it is the whole argument.

67.5 percent of Naperville residents hold a bachelor’s degree or higher, across a city of 149,540 people — the third largest in Illinois. Unemployment runs typically below the national average, and the city added more than 10,000 residents in the past decade.

Scale is the point. Several markets we cover have higher attainment percentages, but they are villages of twenty thousand. Naperville combines a high attainment rate with genuine population, which produces an absolute number of degree-holding residents that no comparable suburban market matches.

The education infrastructure reinforces it. Naperville 203 and Indian Prairie 204 are both nationally recognized districts, with IPSD serving roughly 28,500 students across Naperville, Aurora, Bolingbrook, and Plainfield. For an employer recruiting mid-career professionals with families, school quality is a retention argument as much as a lifestyle one.

Who Employs People in Naperville?

• Edward Hospital — a 309-bed Level II trauma center at 801 South Washington Street with more than 60 medical and surgical specialties, founded in 1907 as the Edward Sanitorium and reorganized as Edward Hospital in 1955. It is reported to employ over 5,000 people locally and is part of Edward-Elmhurst Health, now Endeavor Health, one of the larger integrated health systems in Illinois.
• Nicor Gas — corporate headquarters, in Naperville since 1962
• Nokia Bell Labs — the direct descendant of the Bell Laboratories operation that arrived in 1964
• BP America — successor to the Amoco Research Center, here since 1969
• KeHE Distributors — a national leader in natural and specialty food distribution
• Wilton Brands, Ecolab, and others cited including Tellabs and Dukane Precast
• Naperville 203 and Indian Prairie 204 — substantial employers in their own right

Two things stand out for office demand. Naperville has headquarters, not branches — Nicor runs from here. And the medical office demand is real: a 309-bed Level II trauma centre with 60-plus specialties and 5,000-plus employees generates physician practice, diagnostic, and administrative space requirements that a general office market analysis will not capture.

Where Is Office Space in Naperville?

• The I-88 corridor — the Illinois Technology and Research Corridor position, holding Nicor, Nokia Bell Labs, BP, and sixty years of corporate R&D stock. The city’s stated redevelopment priority.
• Downtown Naperville — walkable street-level and mid-rise office around the Metra station, with free municipal parking, the Riverwalk, and the amenity that comes with one of the strongest suburban downtowns in the Midwest.
• The Route 59 corridor — suburban office alongside the Route 59 Metra station and the Fox Valley retail concentration on the Aurora border.
• The Edward Hospital campus area — medical office, diagnostic, and physician practice space around 801 South Washington Street.
• The 5th Avenue Metra station area — the other candidate for the city’s $150,000 special study, and a transit-adjacent redevelopment prospect.

These are genuinely different products. The I-88 corridor offers large floor plates, campus settings, and highway visibility at rents reflecting current underperformance. Downtown offers walkability, amenity, and rail at a premium with older and smaller floor plates. Route 59 offers modern suburban product. The hospital area serves a specific tenant type. A comparable set averaged across all four describes none of them.

Naperville also spans DuPage and Will Counties, and assessment practice differs between them. We confirm the county for a specific building before a letter of intent.

How Good Is Access for Naperville Office?

Among the best in the western suburbs, and the Mayor named it as one of the three reasons high-growth businesses are already in the corridor: proximity, opportunity, and talent.

Naperville sits 28 miles west of Chicago with the Ronald Reagan Memorial Tollway (I-88) along its northern edge, US Route 34 running east to west, and the BNSF Railway through the center. Two Metra stations serve the city — the downtown Naperville station and the Route 59 station on the Aurora border — alongside Amtrak service and Pace rush hour bus routes.

The research adjacency is the part that distinguishes Naperville from every other suburban office market in the region. Fermilab and Argonne National Laboratory are both within reach, which the city explicitly treats as a corridor asset. For an R&D, advanced computing, or scientific instrumentation occupier, that proximity is a recruitment and collaboration argument that no other Chicago suburb can make.

Office Tenant Representation in Naperville — 3,000 to 50,000 SF

Our office tenant representation practice covers the 3,000 to 50,000 square foot range across corporate requirements, R&D and flex office, medical office, and multi-tenant space.

For occupiers entering or expanding in Naperville, we run the full process: requirement definition, market survey across listed and off-market availability, building inspection, and comparative analysis of total occupancy cost rather than headline rent.

Four things drive a Naperville office decision.

Corridor versus downtown. They serve different tenants at different rents with different amenity, and the choice should follow your staff and your clients. The I-88 corridor is where the leverage currently sits.

Timing against the redevelopment. The city has publicly called the corridor underperforming and committed $150,000 to studying it. If that work succeeds, terms tighten. Taking space now, with longer term and stronger options, is a defensible strategy and we will say so plainly rather than pretend the market is tighter than it is.

Which county. Naperville spans DuPage and Will, and the tax and assessment treatment differs. We establish this for a specific building before a letter of intent.

Total occupancy cost. We model on a gross effective basis including the tax line, operating expenses, parking, and the real cost of build-out — particularly relevant in older corridor stock where a fit-out can exceed the rent saving.

We negotiate the LOI and the lease — free rent, tenant improvement allowances, expansion and contraction rights, renewal and termination options, and parking. We work both sides of the table in Naperville, and we tell you which side we are on before an assignment begins.

Office Leasing, Sales & Property Management in Naperville — Buildings Up to 1,000,000 SF

For owners and investors we handle office leasing, investment sales, and property management, from single-tenant buildings to multi-building campuses up to 1,000,000 square feet.

Landlord Representation

We build and execute the leasing plan: positioning against comparables from transactions we negotiated ourselves, marketing to the regional and national occupier base, prospect qualification, and negotiation through lease execution. For a Naperville corridor building that means marketing to the industries the city has identified as targets — agriculture and food technology, quantum and advanced computing, sports and hospitality — alongside the traditional corporate and R&D base, because the city is about to spend money attracting exactly those sectors. We report activity honestly, including when the market is telling you something you did not want to hear.

Investment Sales

Office assets trade on tenant credit, remaining lease term, building quality, and the durability of the employment base. Naperville’s case is unusually strong on the last of those: 67.5 percent bachelor’s degree attainment across 149,540 residents, headquarters rather than branches, a 309-bed hospital system, and sixty years of continuous corporate R&D tenancy. We work with 1031 exchange buyers on identification and closing deadlines and underwrite against comparables from transactions we negotiated.

Corridor Repositioning

The I-88 corridor is a repositioning market and should be underwritten as one. The city has said so publicly, which is more candor than most municipalities offer and considerably more useful than a brochure. We model the as-is income as the base case, treat any redevelopment scenario as separate upside, and price capital requirements on older corporate stock explicitly rather than assuming a light refresh will let. A 200-acre R&D campus built for a 1966 tenant is not a 2026 office product without investment, and pretending otherwise helps nobody.

Who Manages Office Property in Naperville?

Van Vlissingen and Co. provides comprehensive property management for office assets in Naperville:

• Lease administration, rent collection, and enforcement of lease terms
• CAM and tax reconciliation, prepared to withstand tenant audit
• Building systems, HVAC, elevator, and life safety maintenance programs
• Janitorial, landscaping, snow removal, and parking management
• Vendor selection, contract negotiation, and performance oversight
• Monthly financial reporting, annual budgeting, and capital planning
• Tenant relations, renewal coordination, and suite turnover

Because Naperville spans DuPage and Will Counties, an operating expense budget built on one set of assessment assumptions will not hold across the city. We budget and reconcile by county. Older corridor buildings also carry envelope, mechanical, and life safety requirements that newer product does not, and R&D and laboratory space carries obligations — ventilation, power, and in some cases compliance documentation — that a standard office management scope does not contemplate. Those belong in the lease and the management brief from the start.

What Is Van Vlissingen’s Office Experience?

Van Vlissingen and Co. performs more than 100 commercial real estate transactions annually, and our team has completed over $3 billion in transaction volume.

The relevant credential for an office assignment is that we own and operate office space rather than only broker it. We developed and still manage 870 acres and more than 6 million square feet across three corporate parks, of which Corporate Woods in Vernon Hills is roughly 25 percent office across more than 60 buildings on 340 acres. Corporate Grove in Buffalo Grove carries office, research, and high-tech space across 200 acres, and Lincolnshire Corporate Center covers a further 330 acres.

That experience is directly relevant here. Corporate Grove was developed in the mid-1980s for office, research, and high-tech occupiers — the same tenant profile the I-88 corridor was built for two decades earlier. We have leased, re-tenanted, and repositioned that kind of space on our own balance sheet through multiple market cycles, including the period since 2020 when the office market changed more than at any point in that history.

Naperville Office Real Estate FAQs

Why is Naperville significant for office real estate?

Because the Illinois Technology and Research Corridor began here. Northern Illinois Gas, now Nicor, moved its research and administrative facilities to Naperville in 1962, Bell Laboratories followed in 1964, and the Amoco Research Center, now BP, arrived in 1969. In 1966 AT&T Indian Hill Bell Labs, later Lucent Technologies, opened an R&D facility on a 200-acre site off Naperville and Warrenville Roads with 700 employees. That sequence created one of the four principal economic centers in suburban Chicago, alongside the I-90 Golden Corridor, the I-94 Lakeshore Corridor, and the I-55 Industrial Corridor, and the corridor still holds Nicor’s headquarters, Nokia Bell Labs, and BP America.

Is the I-88 corridor performing well?

Not currently, and the city says so itself. In his May 2026 State of the City address, Mayor Scott Wehrli called the I-88 corridor the largest and most significant redevelopment opportunity in Naperville’s history, while a Naperville Development Partnership report found much of it underperforming relative to its potential. The city has budgeted $150,000 for a special study on either the I-88 corridor or the properties around the 5th Avenue Metra station, and a corridor branding study is proceeding. For a tenant, underperforming means available and negotiable, and the leverage on rent, term, allowances, and options is real right now.

What is the Naperville workforce like?

The deepest educated labor pool in the western suburbs. Roughly 67.5 percent of residents hold a bachelor’s degree or higher, across a city of 149,540 people, the third largest in Illinois, with unemployment typically below the national average and more than 10,000 residents added in the past decade. Several markets we cover have higher attainment percentages, but they are villages of twenty thousand. Naperville combines a high rate with genuine population, which produces an absolute number of degree-holding residents that no comparable suburban market matches.

Which employers drive office demand in Naperville?

Nicor Gas runs its corporate headquarters here, in Naperville since 1962. Nokia Bell Labs is the direct descendant of the Bell Laboratories operation that arrived in 1964, and BP America succeeded the Amoco Research Center that came in 1969. Edward Hospital is a 309-bed Level II trauma center at 801 South Washington Street with more than 60 medical and surgical specialties, reported to employ over 5,000 people locally, and part of Edward-Elmhurst Health, now Endeavor Health. KeHE Distributors, Wilton Brands, Ecolab, Tellabs, and Dukane Precast are also cited, alongside the Naperville 203 and Indian Prairie 204 school districts.

Where are Naperville’s office submarkets?

Five, and they trade differently. The I-88 corridor holds sixty years of corporate R&D stock and is the city’s stated redevelopment priority. Downtown Naperville offers walkable office around the Metra station with free municipal parking and Riverwalk amenity. The Route 59 corridor offers modern suburban product near its own Metra station on the Aurora border. The Edward Hospital campus area carries medical office and physician practice space. The 5th Avenue Metra station area is the other candidate for the city’s $150,000 study and a transit-adjacent redevelopment prospect.

How good is access and research adjacency in Naperville?

Among the best in the western suburbs. Naperville sits 28 miles west of Chicago with the Ronald Reagan Memorial Tollway along its northern edge, US Route 34 running east to west, and the BNSF Railway through the center. Two Metra stations serve the city, alongside Amtrak and Pace rush hour bus routes. The distinguishing factor is research adjacency: Fermilab and Argonne National Laboratory are both within reach, which the city explicitly treats as a corridor asset. For an R&D, advanced computing, or scientific instrumentation occupier, that proximity is a recruitment and collaboration argument no other Chicago suburb can make.

Should I take space in the corridor now or wait?

Now is the stronger position if the space suits you. The city has publicly called the corridor underperforming and committed money to changing that, which means terms are more negotiable today than they will be if the repositioning succeeds. Taking space with longer term and stronger renewal and expansion options is a defensible strategy. We will say that plainly rather than pretend the market is tighter than it is, and we will also tell you if a specific building’s capital requirements make the headline rent misleading.

What size office space does Van Vlissingen and Co. handle in Naperville?

Our office tenant representation practice covers 3,000 to 50,000 square feet in Naperville and across DuPage and Will Counties, spanning corporate requirements, R&D and flex office, medical office, and multi-tenant space. On the leasing, sales, and property management side we handle buildings up to 1,000,000 square feet.

Does Naperville span more than one county?

Yes, DuPage and Will. Property assessment practice differs between them, so an operating expense budget built on one side of the line will not necessarily hold on the other, and the county should be established for a specific building before a letter of intent rather than after.

Who is the best commercial office broker in Naperville?

Choose a brokerage that will tell you the corridor is underperforming rather than only that it is historic, because the first fact creates leverage and the second does not. Van Vlissingen and Co. developed and still manages 870 acres and more than 6 million square feet across three corporate parks, including Corporate Grove in Buffalo Grove, built in the mid-1980s for office, research, and high-tech occupiers — the same tenant profile the I-88 corridor was built for two decades earlier. We perform more than 100 transactions annually with over $3 billion in team volume, and the firm has operated in Chicagoland commercial real estate since 1879. Gordon Lamphere leads the office practice.

Do you manage office property in Naperville?

Yes. We provide comprehensive property management for Naperville office assets, covering lease administration, CAM and tax reconciliation, building systems and life safety programs, janitorial and parking management, vendor oversight, and monthly financial reporting. Because Naperville spans DuPage and Will Counties we budget and reconcile by county, and R&D and laboratory space carries ventilation, power, and compliance obligations that a standard office management scope does not contemplate.
