Tenant Improvements in Naperville, IL

Tenant Improvements Across
Naperville & the I-88 Corridor

Tenant improvement projects are different from ground-up commercial construction - they happen inside existing buildings, often while other tenants are in the building, and they involve a three-way relationship between the tenant, the landlord, and the contractor. SilverBullet has navigated that relationship across office parks, flex industrial buildings, medical facilities, and retail centers throughout DuPage and Will County.

We work from the landlord's work letter, coordinate required approvals with building management, and deliver a finished space that meets both the tenant's needs and the landlord's standards. Our permit experience across Naperville, Lisle, Aurora, Warrenville, Bolingbrook, and surrounding municipalities means we understand the local review process - and we start it early enough that permits don't delay your commencement date.

If you're negotiating a commercial lease in the Naperville area and need a construction cost estimate to inform your TI allowance negotiation, call us before you sign. We've helped tenants across DuPage County understand their real buildout costs before the landlord's number was locked in.

FAQ

Common Questions About
Tenant Improvements

What is a tenant improvement (TI) allowance?

A TI allowance is money the landlord contributes toward your buildout costs, typically expressed as a per-square-foot amount (e.g., $40/sq ft TI). It's one of the most negotiable parts of a commercial lease. Knowing your real buildout cost before signing helps you negotiate an allowance that covers your actual needs.

How much do tenant improvements cost in Naperville?

TI costs vary by scope - a basic refresh (paint, carpet, lighting) might run $20–$35/sq ft. A full reconfiguration with new mechanical and custom finishes runs $60–$100+/sq ft. We provide detailed estimates so you can compare against your proposed TI allowance before you sign.

Do tenant improvements require permits?

Yes - most tenant improvements involving framing, electrical, or mechanical work require a building permit and inspections. SilverBullet manages the full permit process, including any landlord-required approvals.

Can you start construction before permits are approved?

We can do limited demo and site prep in some cases with landlord consent, but framing, electrical, and mechanical work cannot begin without permit approval. We start the permit process immediately after lease execution to minimize this gap.

Do you do tenant improvements outside of Naperville?

Yes - SilverBullet has completed TI work across Naperville, Aurora, Lisle, Bolingbrook, Wheaton, Downers Grove, Plainfield, Romeoville, Joliet, Warrenville, Woodridge, Oswego, Batavia, Geneva, St. Charles, and Montgomery, with particular experience along the I-88 commercial corridor.
