What Is a Commercial Tenant Improvement Project?

A commercial tenant improvement, often called a TI project or tenant build-out, is the process of modifying an existing commercial space to meet the needs of a new or existing tenant.

Our tenant improvement services page explains how Brady supports a commercial build-out. If you already manage the project handoffs, continue to the property manager’s TI guide.

Tenant improvements are common in office buildings, retail centers, medical spaces, industrial buildings, warehouses, restaurants, and mixed-use properties. The goal is to make the space functional, code-compliant, and aligned with the tenant’s business operations.

What Does a Tenant Improvement Project Include?

A tenant improvement project can be simple or complex depending on the condition of the building and the tenant’s needs.

Common tenant improvement scopes include:

• Interior demolition
• New walls and partitions
• Doors, frames, and hardware
• Drywall, patching, and painting
• Flooring and base installation
• Ceiling grid and ceiling tile work
• Lighting and electrical upgrades
• HVAC modifications
• Plumbing for restrooms, sinks, or break rooms
• Fire sprinkler and fire alarm modifications
• Millwork, reception desks, cabinets, and counters
• Glass office fronts and conference rooms
• ADA accessibility improvements

For some spaces, tenant improvements may also include structural work, equipment pads, exterior openings, roof penetrations, utility upgrades, or site improvements.

Does a Tenant Improvement Require a Permit?

In most cases, yes. Commercial tenant improvements typically require building permits when the work includes demolition, new walls, electrical, plumbing, mechanical, structural changes, accessibility upgrades, or life-safety modifications. Some jurisdictions state that a building permit is required for commercial tenant improvements, and additional planning review may also be required depending on the location and scope.

Because requirements vary by city, it is important to confirm the permitting process before starting work.

Who Is Involved in a Tenant Improvement Project?

A typical TI project may involve the tenant, property owner, landlord, architect, engineers, general contractor, city building department, fire department, property manager, and sometimes the tenant’s vendors for signage, furniture, security, low voltage, or equipment.

A good general contractor helps coordinate the construction side of the process and works with the design team to make sure the project is planned correctly.

Why Planning Matters

Tenant improvements often need to be completed quickly, especially when a lease start date or business opening date is involved. Early planning helps prevent delays, change orders, and unexpected costs.

The best results usually happen when the contractor reviews the space before drawings are finalized. This helps identify issues with utilities, access, existing building conditions, and potential code concerns.

An actual tenant-improvement example

Brady Construction Group remodeled the Audi and Volkswagen training center in Eastvale, California, as a tenant-improvement project. Brady also supports the whole building with facility maintenance. The project illustrates two related needs: adapting an existing commercial space for its users and maintaining the building during ongoing operation.

Define the boundary of your project

• What is changing inside the tenant’s space?
• Which existing building systems or common areas may be affected?
• What belongs to the landlord, tenant, or equipment vendor?
• Which drawings, approvals, and existing-condition information are available?
• Who will manage the finished space and request future service?

Use pre-construction planning to resolve these questions before final pricing. Permit requirements should be confirmed with the responsible jurisdiction for the actual scope; see our commercial permit planning guide.
