Whether you're a landlord preparing a space for a new tenant or a business owner customizing a leased space to fit your operations, tenant improvement (TI) projects come with their own set of rules, costs, and pitfalls that differ from ground-up construction. Here's what property owners and tenants in the Fresno area should understand before starting a TI project.
‍

What Counts as a Tenant Improvement?

Tenant improvements are the customizations made to a commercial space to fit a specific tenant's needs, anything from new walls, flooring, and lighting to full HVAC reconfiguration, electrical upgrades, or ADA-compliance updates. TI work is common in office buildings, retail centers, and medical or professional suites where each new tenant has different space requirements than the last.
‍

Who Pays for What?

One of the first things to clarify before any work begins is the tenant improvement allowance, the amount, if any, the landlord is contributing toward the buildout, usually negotiated as part of the lease. Costs beyond that allowance typically fall to the tenant. Getting a clear, written scope of work and cost estimate before lease signing helps avoid disputes down the line about who's responsible for overages.
‍

Questions to Ask Before You Start

• What is included in the tenant improvement allowance, and what happens if costs exceed it?
• Will this buildout require permits, and how long does that typically take in this jurisdiction?
• Are there existing conditions (electrical capacity, structural elements) that could add unexpected cost?
• Who is responsible for the space if delays push back the tenant's planned move-in date?

Common Buildout Considerations

1. Permits and code compliance. Even seemingly minor changes like moving a wall, adding plumbing, or updating electrical usually require permits thr

ough the City of Fresno or Fresno County. ADA compliance is a frequent trigger point, especially for older buildings undergoing their first upgrade in years.

On the tenant improvement for Vocation Plus Connections in Fresno's Tower District, for example, our team worked to bring a historic building up to current accessibility and functionality standards while preserving its original character, a balance that's common when older Central Valley buildings take on new tenants.

2. Existing building systems. Older commercial buildings in central Fresno may have HVAC, electrical, or plumbing systems that need upgrading to support a new tenant's use. For example, converting a retail space into a medical office often requires significantly more mechanical and electrical work than a straightforward office-to-office change.

Our 5,000 sq. ft. tenant improvement for Santé Health in Clovis, for instance, involved building out 12 fully equipped exam rooms and coordinating the space to support four physicians, well beyond what a typical office suite requires.

3. Timeline expectations. TI projects are frequently done under a lease deadline, since tenants want to move in and start operating as soon as possible. Building in realistic timeframes for permitting, inspections, and any material lead times helps avoid costly delays or lease penalties.

For the Barrows physical therapy office in Madera, we worked with the owner, the architect, and the City of Madera to transform a run-down former PG&E equipment building, one many assumed would be torn down, into a fully refurbished, code-compliant facility, a project that took considerably more planning and coordination than a standard buildout.

4. Working around existing tenants. In multi-tenant buildings, TI work often needs to happen without disrupting neighboring businesses, meaning contractors need experience coordinating access, noise, and safety in occupied buildings.

Both the Santé Health and Dr. Ben Magleby Family Dentist buildouts, for example, took place within the Herndon Professional Center and Herndon Armstrong Professional Center in Clovis, multi-tenant buildings where construction had to be coordinated around other active businesses.

Recent Tenant Improvement Projects in Fresno & the Central Valley

A few examples of the range of TI work we've completed for property owners and tenants across the region:

Santé Health – Medical Office, Clovis. A 5,000 sq. ft. medical facility buildout with 12 fully equipped exam rooms, planned and constructed to support four physicians while meeting clinical, operational, and regulatory requirements, with room to scale as the practice grows.

Northside Dental – Dental Office, Fresno. A modern dental office built in close coordination with the practice owner, project architect, and dental equipment vendors, right down to the smallest details of the client's vision, including transporting and installing a large custom saltwater fish tank for the reception area.

Barrows Training and Physical Therapy – Madera. The adaptive reuse of a former PG&E equipment building, transformed from a structure many considered beyond saving into a modern, fully functional physical therapy office, completed in partnership with the owner, the project architect, and the City of Madera.

Vocation Plus Connections – Fresno (Tower District). A historic building tenant improvement that balanced preservation of the building's original character with modern upgrades to accessibility and functionality. This project was the first of six we've since completed for the client, a partnership built on that initial project's success.

Frequently Asked Questions About Tenant Improvements in Fresno
‍

What is considered a tenant improvement in commercial construction?

A tenant improvement (TI) is any modification made to a commercial space to meet the needs of a specific tenant. This can include new walls, flooring, lighting, electrical work, plumbing, HVAC modifications, accessibility upgrades, and other changes to office, retail, medical, or professional spaces.

How much does a commercial tenant improvement cost in Fresno?

Tenant improvement costs in Fresno vary depending on the size of the space, existing building conditions, materials, and the extent of the buildout. Projects involving significant HVAC, plumbing, electrical, or structural work typically cost more than cosmetic improvements. A contractor can evaluate the space and develop a more accurate project scope and budget before construction begins.

How long does a tenant improvement project take?

The timeline for a tenant improvement project depends on the scope of work, permitting requirements, inspections, material lead times, and existing conditions. Planning early and involving a contractor before a lease or move-in deadline is finalized can help establish a realistic construction schedule.

Do tenant improvements require permits in Fresno?

Many commercial tenant improvements require permits, particularly when the project involves changes to walls, plumbing, electrical systems, HVAC, accessibility, or other building systems. Permit requirements vary by project and jurisdiction, so working with a contractor familiar with Fresno, Clovis, and Central Valley permitting requirements can help streamline the process.

Who typically pays for tenant improvements?

Responsibility for tenant improvement costs is generally determined by the lease agreement. A landlord may provide a tenant improvement allowance that covers some or all of the buildout, while the tenant is typically responsible for costs that exceed the agreed-upon allowance. Establishing the scope and budget before signing a lease can help both parties understand their financial responsibilities.

When should I involve a contractor in a tenant improvement project?

Ideally, a contractor should be involved as early as possible, potentially even before the lease is finalized. Early contractor involvement can help identify potential building limitations, estimate construction costs, evaluate the proposed scope, and establish a realistic timeline before major commitments are made.

Can tenant improvement construction happen in an occupied building?

Yes. Tenant improvements are frequently completed in buildings where other businesses remain open. An experienced commercial contractor can coordinate construction access, scheduling, noise, safety, and other logistics to help minimize disruption to neighboring tenants and ongoing operations.
