Tenant Improvements 101: Costs, Allowances, and Build-Outs Explained

Leasing a new commercial space is an exciting milestone—but for many business owners in Las Vegas, it can also feel overwhelming. Between negotiating a lease, understanding tenant improvement (TI) allowances, and figuring out how to turn an empty shell into a functional space, the process can quickly become complex.

This guide breaks down the basics of tenant improvements, what Las Vegas tenants should know before signing a lease, and why working with a design-build team is often the best way to open your space faster, stay within budget, and avoid unnecessary headaches.

What Are Tenant Improvements?

Tenant improvements (often called TIs) are the interior build-outs or modifications made to a leased commercial space so it meets your business’s operational needs and brand standards.

Common tenant improvements include:

• Interior walls and layouts
• Electrical, lighting, and data systems
• HVAC modifications
• Plumbing installations
• Flooring, ceilings, and finishes
• ADA compliance upgrades
• Custom millwork or branded elements

Tenant improvements are common across many industries including retail, restaurants, medical offices, professional services, and hospitality spaces. Most projects must meet safety and accessibility requirements governed by building codes such as those maintained by the International Code Council.

How Tenant Improvements Work in Las Vegas

Tenant improvement projects in Las Vegas follow a process that typically includes design, permitting, construction, and final inspections before the business can open.

While every project is different, most tenant improvements involve the following steps:

• Evaluating the existing space and infrastructure
• Developing preliminary layouts or test-fit plans
• Coordinating with local jurisdictions for permits
• Completing construction and required inspections

Depending on the jurisdiction—such as Clark County or the City of Las Vegas—commercial projects may require plan review before permits are issued. Working with a contractor familiar with the local permitting process can significantly reduce delays and keep projects moving efficiently.

How Much Do Tenant Improvements Cost?

Tenant improvement costs can vary widely depending on the type of business and the condition of the space. Restaurants, medical offices, and hospitality projects typically require more infrastructure than basic office or retail build-outs.

Common factors that influence tenant improvement costs include:

• The size of the space
• Mechanical, electrical, and plumbing upgrades
• Kitchen or specialty equipment requirements
• Custom finishes or branded design elements
• Local permitting and inspection requirements

Second-generation spaces—those previously built out for a similar use—often require less work than new shell spaces. Early planning and realistic budgeting are key to ensuring the project aligns with both the lease terms and the tenant improvement allowance.

Understanding TI Allowances in Las Vegas Leases

Many commercial leases include a tenant improvement allowance (TIA), which is money the landlord contributes toward the cost of building out the space.

While this sounds straightforward, TI allowances often come with important conditions.

Things tenants should consider include:

• The allowance may only cover basic construction, not upgrades
• Funds are typically reimbursed after construction is complete
• Costs exceeding the allowance become the tenant’s responsibility
• Unused allowance dollars may not roll over or be refundable

Understanding the structure of your TI allowance before signing the lease can help avoid budget surprises later. Commercial real estate resources such as tenant improvement allowance guidance explain how these incentives typically work within leases.

The Biggest Mistake New Tenants Make

One of the most common mistakes business owners make is treating design and construction as separate processes—hiring a designer first and then bidding the project to contractors later.

In fast-moving markets like Las Vegas, this approach can create delays, budget conflicts, and costly revisions.

Common problems include:

• Designs that exceed the TI budget
• Multiple change orders during construction
• Longer timelines
• Misalignment between designers and contractors
• Permit or inspection delays

Why Design-Build Is Often the Best Option for Tenant Improvements

At Burke Special Projects, design and construction work together under one team, one contract, and one point of accountability. For business owners leasing space in Las Vegas, this approach provides several advantages.

1. Cost Control From Day One

Design decisions are shaped around the actual project budget and TI allowance, helping prevent costly surprises later.

2. Faster Timelines

Because design and construction phases can overlap, projects often move faster through permitting and procurement.

• Faster permitting
• Earlier material ordering
• Shorter overall project schedules

3. Fewer Change Orders

Contractors involved early in the design process can identify potential conflicts before construction begins.

4. Single Point of Responsibility

Instead of coordinating multiple vendors, business owners work with one team responsible for design, budgeting, scheduling, and construction delivery.

5. Local Market Expertise

Local knowledge can save weeks—or even months—during construction. A Las Vegas design-build contractor understands:

• Local permitting requirements
• Clark County and city review processes
• Local subcontractor networks
• Market-specific construction costs

When Should You Bring in Burke Special Projects?

Ideally, before you sign the lease.

Early involvement allows the team to:

• Review the space before committing
• Provide realistic construction estimates
• Help negotiate tenant improvement allowances
• Identify potential design or infrastructure issues
• Align the layout with operational needs

Early planning gives tenants leverage and clarity—rather than surprises during construction.
