Commercial Renovation Costs: A Comprehensive Guide (2025)

Learn how to estimate commercial renovation costs and budget smarter. Avoid surprises and get your project off the ground with confidence.

You know your building needs work, but how do you even start figuring out what it’ll cost? If you're like most business owners, guessing isn't an option. You need real numbers you can trust before you can move forward.

Understanding commercial renovation costs isn’t just about budgeting—it’s about making smart decisions that protect your investment and your future.

Whether you're planning a simple refresh or a major overhaul, knowing what drives the price (and what pitfalls to avoid) will save you time, stress, and money. Here's what you need to know before you pick up the phone.

What is a commercial renovation?

A commercial renovation makes a space work better for the people who use it every day.

Renovations can range from cosmetic upgrades like new flooring, paint, and lighting to full-scale overhauls that involve tearing down walls, reworking mechanical systems, and redesigning layouts for better flow and efficiency.

An excellent renovation considers how a space functions, how it supports your business, and how it sets you up for long-term success.

Commercial Renovation Cost Factors

Several key factors can cause the price to rise or fall, depending on the specifics of your project. Here’s what drives the numbers:

1. Materials and Labor

The quality of materials you choose and the labor required to install them have a major impact on your final cost. High-end finishes, specialty installations, and custom work will cost more than standard commercial-grade options. Labor availability and skill level also affect your timeline and your budget.

1. Building Use

What you’re renovating matters. Medical offices, warehouses, restaurants, and corporate headquarters all have different compliance needs, design standards, and mechanical requirements. Spaces with specialized equipment, hygiene regulations, or heavy infrastructure (like hospitals and labs) tend to have higher renovation costs than general office spaces.

1. Building Location

Where your building is located can influence material prices, labor costs, and even permit fees. Renovating in a busy downtown area typically costs more than working in suburban or rural settings, partly due to access issues, staging challenges, and higher contractor demand.

1. Adding Building Amenities

If you’re adding new amenities—like upgraded break rooms, wellness spaces, ADA-compliant entrances, or smart technology—expect higher costs. These upgrades add value but require additional planning, materials, and often specialized contractors to get the job done right.

1. Updated Electrical Systems

Older buildings often need significant electrical updates to meet today’s codes and power demands. Adding new outlets, upgrading panels, or integrating energy-efficient systems can be a hidden cost if it isn’t caught early in planning.

1. Building Permit Fees

Permits aren’t optional—and they aren’t free. Local jurisdictions require permits for most structural, mechanical, plumbing, and electrical work. Fees vary widely based on location and project scope, so it’s important to factor them into your upfront budget.

Average Cost of Commercial Renovations (Cost Per Sq. Ft.)

When you’re budgeting for a commercial renovation, one of the first numbers people want to know is the cost per square foot—and it’s a smart place to start. While prices vary depending on your industry, location, and scope of work, here’s a general idea of what you can expect:

Basic Office Renovations: $50–$100 per sq. ft.

Cosmetic updates like paint, flooring, lighting, and minor layout changes fall into this range.

Mid-Level Renovations: $100–$175 per sq. ft.

Projects that involve electrical upgrades, HVAC improvements, moderate structural changes, and higher-end finishes typically land here.

Full-scale or Specialized Renovations: $175–$300+ per square foot.

Healthcare facilities, labs, restaurants, and spaces requiring heavy compliance upgrades or specialized systems can easily exceed $200 per sq. ft.

How to Estimate Commercial Renovation Costs

Getting a real handle on commercial renovation costs isn’t about guessing—it’s about creating a smart, structured estimate that reflects your space, your needs, and your goals. Here's how to start building a realistic budget:

1. Define the Scope of Work

First, get clear on what you’re actually changing. Are you refreshing finishes, reconfiguring layouts, or replacing major systems? A full gut renovation costs a lot more than a cosmetic facelift. Knowing the full scope early helps avoid "scope creep" that can blow up your budget later.

2. Understand Your Space

Older buildings or commercial spaces that need a lot of mechanical, plumbing, or electrical updates will cost more. Similarly, specialized spaces—like healthcare facilities or food service environments—carry additional regulatory and equipment costs you’ll need to plan for.

3. Break Costs Into Categories

Instead of lumping everything into a single number, break your budget down by category:

• Demolition and site prep
• Structural changes
• Mechanical, electrical, and plumbing upgrades
• Finishes and materials
• Permits and fees
• Contingency (10–20% for unexpected issues)

4. Calculate the Cost Per Square Foot

Once you know your scope, apply a rough cost per square foot based on your project type. Then adjust up or down depending on the quality of materials, customization, and complexity.

5. Factor in Project Timing

The longer a renovation takes, the more it costs in terms of labor, rental space, and downtime. Seasonal labor demand, supply chain delays, and permitting processes can all impact your timeline and your bottom line.

6. Partner with a Construction Pro Early

An experienced contractor or design and construction firm can help you build a much more accurate estimate early in the process. They’ll help you define scope costs clearly up front—so you can plan smart, avoid budget overruns, and get your project off the ground without nasty surprises.

The cost to build a 50,000 square foot commercial building can range from $125 to $400 per square foot, depending on factors like building type, finishes, mechanical systems, and location. That means total costs can range from $6.25 million to $20 million or more.

How to calculate renovation costs?

To calculate renovation costs, define the scope of work, estimate the cost per square foot based on the project type, and add in expenses for permits, materials, labor, and contingency. A rough formula:

Total Renovation Cost = (Square Footage × Cost per Sq. Ft.) + Additional Costs + Contingency.

How much does a commercial buildout cost?

A commercial buildout typically costs between $50 and $200 per square foot, depending on the level of customization, the type of space (office, medical, retail), and whether structural changes are needed. High-end buildouts with custom finishes and advanced systems can cost more.
