Commercial Lease Insights
Tenant improvement allowance (TI allowance) is commonly negotiated in commercial real estate leases to help offset office build-out, retail renovation and leasehold improvement costs.
Landlords often provide a tenant improvement allowance per square foot, while tenants cover any remaining build-out expenses exceeding the negotiated allowance budget.
Commercial brokers, investors, landlords, startups and enterprise tenants use tenant improvement calculations when evaluating lease agreements, occupancy costs and long-term property investment decisions.

What Is A Tenant Improvement Allowance?
A tenant improvement allowance, often called TI allowance, is a negotiated amount provided by a landlord to help cover renovation and customization expenses inside a leased commercial property.
These funds are commonly used for office construction, interior upgrades, flooring, electrical work, conference rooms, retail build-outs, HVAC modifications, lighting systems and other leasehold improvements required by the tenant.
Tenant Improvement Allowance Formula
TI Allowance = Leased Square Footage × Allowance Per Square Foot
Many commercial lease agreements specify a fixed allowance amount per square foot. The larger the leased space, the larger the potential landlord-funded contribution.
How This Tenant Improvement Calculator Works
This calculator analyzes commercial lease improvement costs using several key inputs, including square footage, TI allowance, build-out costs, lease terms and projected rent escalation assumptions.
- Enter total leased commercial space.
- Add tenant improvement allowance per square foot.
- Enter estimated build-out cost per square foot.
- Add lease term information.
- Review landlord contribution and tenant cost instantly.
Commercial Build-Out Cost Example
Imagine a business leases 10,000 square feet of office space. The landlord offers a tenant improvement allowance of $50 per square foot while estimated renovation costs reach $75 per square foot.
TI Allowance = 10,000 × $50 = $500,000
Build-Out Cost = 10,000 × $75 = $750,000
Tenant Contribution = $750,000 − $500,000
In this scenario, the tenant would still need to fund the remaining renovation expenses unless additional landlord concessions or lease incentives are negotiated.
Common Tenant Improvement Expenses
Commercial renovation budgets vary significantly depending on industry, location, building condition and operational requirements. Office tenants, medical practices, retail businesses and restaurants often have very different build-out costs.
| Improvement Type | Typical Cost Range | Common Usage |
|---|---|---|
| Office Build-Out | $40 – $120 / Sq Ft | Corporate offices and startups |
| Retail Renovation | $50 – $200 / Sq Ft | Stores and shopping centers |
| Medical Space | $150 – $400+ / Sq Ft | Clinics and healthcare facilities |
| Restaurant Build-Out | $200 – $600+ / Sq Ft | Food service operations |
These costs may include flooring, electrical systems, plumbing upgrades, lighting, HVAC modifications, furniture, interior construction and technology infrastructure.
Landlord Contribution vs Tenant Contribution
One of the most important commercial lease negotiation topics involves determining how renovation expenses are divided between landlords and tenants.
| Cost Responsibility | Landlord | Tenant |
|---|---|---|
| Basic Building Improvements | Usually Covered | Rarely |
| Branding & Custom Design | Sometimes | Commonly Covered |
| Furniture & Equipment | Rarely | Usually Covered |
| Structural Upgrades | Commonly Covered | Sometimes Shared |
