Budgeting a Tenant Improvement: Step 3

Build a budget that covers the whole project, not just the construction contract.

The third stage of a tenant improvement is turning the plan and permit drawings into a firm budget. A good budget does more than total up bids. It accounts for every cost the project will carry and protects against the surprises that existing buildings tend to hide.

This guide explains how tenant improvement budgets are usually structured and where they most often go wrong.

Hard Costs and Soft Costs

A complete budget includes both:

Leaving out soft costs and FF&E is one of the most common budgeting mistakes.

The Tenant Improvement Allowance

Many leases include a tenant improvement allowance (TIA) from the landlord:

Our guide to the tenant improvement allowance covers how TIAs are negotiated and paid.

Second-generation spaces that match the program can cost far less than a cold shell.

Contingency

Existing buildings hide conditions that only appear during construction:

Many owners carry a contingency of around 5 to 10 percent, and more for older buildings.

Long-Lead Items and Escalation

Some costs depend on timing:

Buying long-lead items early can protect both the budget and the schedule.

Bids and Change Orders

Frequently Asked Questions

How much does a tenant improvement cost per square foot?

It varies widely by market, building condition, and scope. A light refresh can cost a fraction of a full build-out with new restrooms and systems. Local contractor pricing on your actual drawings is the only reliable number.

Does the tenant improvement allowance cover furniture?

Often not. Many allowances are limited to construction and some soft costs. Check the work letter for what qualifies.

How much contingency should we carry?

Many owners carry around 5 to 10 percent of construction cost, and more for older buildings or incomplete drawings.
