What Are Tenant Improvements? Commercial Build-Out Guide
Table of Contents
When leasing commercial space, the existing layout rarely matches your business needs exactly. Tenant improvements (TI)—also called a build-out or fit-out—modify the space to suit your specific requirements. Understanding the TI process helps you negotiate better lease terms and create a space that supports your business success.
What Are Tenant Improvements?
Tenant improvements are modifications made to commercial rental space to meet a tenant's specific needs. These range from simple cosmetic changes to complete interior rebuilds.

Understanding TI Allowances
What Is a TI Allowance?
A TI allowance is money the landlord provides to fund improvements. It's expressed as dollars per square foot.
Example:
- Space: 5,000 square feet
- TI Allowance: $35/sq ft
- Total Contribution: $175,000
Current TI Allowance Ranges (Las Vegas)
| Space Type | Typical Range | Notes |
|---|---|---|
| Office (Class A) | $40-$75/sq ft | Higher in premium buildings |
| Office (Class B) | $25-$45/sq ft | Varies by condition |
| Retail | $20-$50/sq ft | Location dependent |
| Industrial | $10-$25/sq ft | Usually minimal TI needs |
| Restaurant | $50-$100+/sq ft | Extensive improvements needed |
Factors Affecting TI Allowances
Landlord Offers More When:
- Strong tenant credit
- Longer lease term
- Larger space
- High-demand building
- Competitive market
Landlord Offers Less When:
- Weak tenant credit

- Soft market
- Space recently improved
- Tenant-specific improvements
The TI Process
Step 1: Space Evaluation
Before signing a lease, assess the space:
What to Evaluate:
- Existing condition and infrastructure
- Required modifications
- Code compliance issues
- Building system capacity
- Landlord restrictions
Get a Professional Opinion: Have a contractor walk the space before finalizing lease terms. This reveals:
- Realistic improvement costs
- Hidden issues
- True TI needs
Step 2: Budgeting
TI Cost Factors:
| Component | Percentage of TI Budget |
|---|---|
| General Construction | 40-50% |
| Mechanical/Electrical | 20-30% |
| Finishes | 15-25% |
| Design/Permitting | 5-10% |
| Contingency | 10% |
Cost per Square Foot by Build-Out Level:
| Level | Cost Range | Description |
|---|---|---|
| Basic | $35-$50/sq ft | Paint, carpet, minimal changes |
| Standard | $50-$80/sq ft | New layout, standard finishes |
| High-End | $80-$125/sq ft | Premium finishes, full build |
| Restaurant/Medical | $100-$200+/sq ft | Specialized requirements |
Step 3: Design and Permitting
Design Process:
- Space planning and layout
- Architectural drawings
- Engineering (if structural/MEP changes)
- Landlord approval
- Building department approval
Permit Requirements: Most TI projects require permits for:
- Construction/building permit
- Electrical permit
- Plumbing permit
- Mechanical permit
- Fire/life safety review
Step 4: Construction
Typical TI Timeline:
| Phase | Duration |
|---|---|
| Design | 2-4 weeks |
| Permitting | 2-4 weeks |
| Construction (basic) | 4-8 weeks |
| Construction (extensive) | 8-16 weeks |
During Construction:
- Coordinate with landlord on access
- Communicate with building management
- Follow building rules and hours
- Pass required inspections
Step 5: Move-In
Pre-Move Checklist:
- Certificate of Occupancy obtained
- Final inspections passed
- Landlord sign-off complete
- Utilities transferred
- Keys/access provided

TI allowances in Las Vegas typically range from $25-$75 per square foot for office space, $20-$50 for retail, and $50-$100+ for restaurants. The actual amount depends on lease length, tenant credit, and market conditions.
In most cases, tenant improvements become property of the landlord at lease end. Some improvements (trade fixtures, equipment) may remain tenant property. This should be clearly defined in your lease.
A basic office build-out takes 4-8 weeks of construction time. More extensive projects take 8-16 weeks. Add 4-8 weeks for design and permitting. Plan for 3-6 months total from lease signing to move-in.
This varies by lease. Many landlords limit TI to permanent improvements (construction, finishes). Some allow furniture, fixtures, and equipment (FF&E). Others exclude moving costs. Negotiate this clearly in your work letter.
You pay the difference out of pocket. Before signing, get realistic construction estimates to understand your total investment. You may be able to negotiate higher TI in exchange for longer lease term or higher rent.
Las Vegas commercial construction costs are typically 10-15% below coastal markets like Los Angeles or San Francisco. However, the city's rapid growth has increased labor costs in recent years. TI costs in Las Vegas average $50-$150 per square foot for office space depending on complexity. Working with a local commercial contractor like CERA Construction ensures competitive pricing with established subcontractor relationships.
