Who is Responsible for Paying for Commercial Tenant Improvement Projects?

The responsibility for funding a commercial tenant improvement project is typically shared between the landlord and the tenant, depending on the scope of the work and the lease agreement.

• Landlord Responsibility: Landlords often provide a tenant improvement allowance to cover the costs of base building systems. This allowance is a negotiated amount intended to help the tenant prepare the space for their business operations.
• Tenant Responsibility: Tenants are generally responsible for funding any electrical modifications or specialized upgrades that exceed the provided allowance. This can include specific wiring for new layouts, dedicated circuit installation, or custom lighting needs.

Because electrical work is a significant portion of these costs, we provide fixed quotes before work begins to help both parties manage their budgets effectively. We also offer local expertise to help you understand how these costs vary by city—for example, average project costs per square foot typically range from $100–$170 in Milpitas to $150–$250 in San Francisco.

Our team ensures all work is permit-ready and compliant with Title 24 and California Department of Industrial Relations mandates, such as seismic retrofitting, regardless of who is covering the specific project costs.
