Signing a lease for your business is a major milestone. But what happens when the space you’ve fallen in love with isn’t quite move-in ready? Maybe it needs accessibility upgrades, a layout reconfiguration, or even a complete redesign to fit your vision. Before you sign on the dotted line, it’s crucial to understand what’s negotiable, how to protect your investment, and how to plan for the improvements ahead.

In this post, we’ll walk through the steps you need to take when leasing a commercial space that requires tenant improvements (TI), renovations, or custom build-outs.

Step 1: Evaluate the Existing Space

Before you begin negotiations, assemble your team of experts. A registered interior designer can assess whether the space meets your layout needs, a general contractor can estimate build-out costs, and an architect is essential if major exterior changes are required.

Key questions to ask:

What structural or mechanical systems need upgrades?
Is the layout adaptable to your needs?
Will ADA compliance or code upgrades be required?

Step 2: Clarify “Who Pays for What” in the Lease

This is where things get real. Tenant improvements (TI) can be negotiated in several ways:

Landlord pays fully (often via a TI allowance)
Tenant pays fully
Cost-sharing arrangement

Make sure these responsibilities are spelled out in the lease.

Tip: Request a tenant improvement allowance (TIA). This is money the landlord offers toward your build-out, typically expressed in dollars per square foot.

Step 3: Negotiate Build-Out Terms & Timing

Use your lease negotiations to solidify:

Scope of improvements
Timeline for completion
Who manages the construction (you or the landlord?)
Permitting responsibilities

Also, negotiate rent commencement timing—ideally, rent starts after improvements are completed, not before.

Step 4: Design Thoughtfully (But Practically)

Now that you know the space is yours (pending improvements), partner with licensed design professionals to design a space that balances:

Functionality
Aesthetic brand alignment
Accessibility and code compliance
Budget and timeline

If you’re in a historic or mixed-use building, check for special design or preservation guidelines.

Step 5: Build Safely, Legally, and on Budget

During construction, ensure:

All permits are secured.
There’s a contingency budget (10–15%) for surprises.
You or your project manager ( which should be your licensed design professionals unless you are well versed in reading construction drawings, commercial construction practices, and building code requirements ) is on-site for key milestones.

Regular inspections are critical to make sure work aligns with plans and codes.

Final Thoughts: Protect Your Investment

Once the improvements are complete, document them thoroughly. Take high-resolution before-and-after photos. Keep copies of all receipts and permits. These records help:

With future negotiations or lease renewals
If you ever decide to sell your business
To confirm improvements are legally recognized

Bonus Tip: Ask the landlord if improvements can be depreciated or credited back if you leave the space early.

Conclusion

Securing a commercial lease that requires tenant improvements can feel overwhelming, but with the right preparation and team, it becomes a strategic opportunity to shape your ideal space. From evaluating the building’s potential and negotiating improvement allowances to thoughtfully designing and managing the build-out, every step plays a critical role in protecting your investment and ensuring your business is set up for success. By approaching the process with clarity, diligence, and professional guidance, you not only avoid costly missteps—you create a space that supports your growth, reflects your brand, and meets the needs of your clients or customers from day one.
