What is a Commercial Tenant Improvement?

A commercial tenant improvement (TI), also known as a build-out or leasehold improvement, refers to the customized alterations made to a leased commercial space to meet the specific needs of the tenant. These improvements can range from simple cosmetic updates like fresh paint and new flooring to complex renovations involving structural modifications, electrical upgrades, plumbing, and HVAC system installations.

Frequently Asked Questions

How long does a commercial tenant improvement take?

The timeline depends on the scope of work. A simple cosmetic refresh may take 2-4 weeks, while a full build-out of a raw space can take 8-16 weeks. We provide a detailed timeline during the planning phase and keep you informed of progress throughout the project.

Who pays for tenant improvements?

Tenant improvements are typically funded through a Tenant Improvement Allowance (TIA) provided by the landlord as part of the lease agreement. The TIA is usually expressed as a dollar amount per square foot. Any costs exceeding the TIA are the tenant’s responsibility. We help you maximize the value of your TIA budget.

Do I need permits for commercial tenant improvements in Renton?

Yes, most commercial tenant improvements require permits from the City of Renton. This includes changes to walls, electrical systems, plumbing, HVAC, and fire suppression systems. As your general contractor, we handle all permitting and inspections on your behalf.

Can you work around our business hours?

Yes. We understand that many commercial TI projects need to minimize disruption to existing business operations. We can schedule work during evenings, weekends, or off-hours to accommodate your needs.

What is included in a typical tenant improvement?

A typical TI project may include demolition of existing finishes, framing and drywall, electrical and lighting, plumbing, HVAC modifications, flooring, painting, cabinetry, and fixtures. The specific scope depends on your business needs and the condition of the existing space.
