How to Finance Your Office Renovation: A Guide to Loans & Borrowing Options

Your office shapes how your team works, how clients perceive you, and how easily you can attract talent. When cramped conference rooms, outdated bathrooms, or a dysfunctional layout start holding your business back, a renovation moves from nice-to-have to necessity. But for most small and medium-sized business owners, figuring out how to fund the project can feel just as daunting as the project itself.

Secured vs. unsecured financing: what's the difference?

Before comparing specific products, it helps to understand the two broad categories your options fall into. Secured financing is backed by collateral—typically commercial property or business assets—which reduces the lender's risk and generally results in lower interest rates for you. Unsecured financing doesn't require collateral, which means faster approval and no assets on the line, but you'll usually pay more in interest.

Important note: Rate ranges are approximations. Your actual terms will depend on your business's financial profile, the lender, and the loan product. Always compare offers from multiple lenders.

Financing options for your office renovation

With the secured-vs.-unsecured framework in mind, here's a closer look at the specific financing products most commonly used for office renovations.

SBA 7(a) loans

The SBA 7(a) program is one of the most popular financing tools for small businesses, and it can be used for a wide range of purposes—including office fit outs, renovations, leasehold improvements, and construction. The SBA doesn't lend directly; instead, it guarantees a portion of the loan (up to 85% for loans of $150,000 or less, and up to 75% for larger loans), which reduces the risk for participating lenders and generally results in more favorable terms for borrowers.

What to know:

• Maximum loan amount: $5 million. Loans up to $500,000 are available through the faster SBA Express program.
• Interest rates are pegged to the prime rate (currently 6.75% as of early 2026) plus a lender markup. The SBA caps maximum rates, which currently range from roughly 9.75% to 14.75% depending on loan size and term.
• Repayment terms can extend up to 25 years for loans tied to real estate. For leasehold improvements and equipment, terms are typically 10 years or matched to the useful life of the asset.
• Most lenders require a credit score of 680 or above, though some may work with lower scores if cash flow and business history are strong.
• Expect a thorough documentation process—including financial statements, tax returns, a business plan, and detailed renovation cost estimates. Timeline from application to funding is typically 45–90 days.

This loan option is ideally suited for established small businesses (generally two or more years in operation) with a solid credit history who need significant funding and can plan ahead for a longer approval timeline.

SBA 504 loans

If your business owns the commercial property you're renovating, the SBA 504 program is designed specifically for major fixed-asset investments, including building improvements and modernization. It uses a unique structure: an SBA-approved lender covers 50% of the project cost, a Certified Development Company (CDC) covers up to 40%, and you contribute at least 10% as a down payment.

What to know:

• Maximum loan amount through the CDC portion: $5 million (up to $5.5 million for certain energy-efficiency projects).
• The CDC portion carries a fixed rate based on Treasury bond yields, which tends to be competitive. The bank portion may be fixed or variable.
• Repayment terms of up to 25 years for real estate-related projects.
• The property must be at least 51% owner-occupied. This won't work for businesses that lease their office space.

This loan option is ideally suited for business owners who own their office property and are planning a large-scale renovation. This is especially true if the project includes energy-efficiency improvements that may qualify for additional SBA benefits.

Commercial bank term loans

A traditional term loan from a bank or credit union gives you a lump sum upfront, which you repay in fixed monthly installments over a set period. These loans may or may not be SBA-backed—many banks offer their own commercial loan products with competitive terms, especially for businesses with strong financials and an existing banking relationship.

What to know:

• Rates and terms vary widely by lender. Businesses with strong credit and collateral may secure rates comparable to SBA loans; others may see higher rates.
• Some banks offer relationship pricing—discounted rates for existing customers who maintain deposit accounts or other products.
• The application process is generally faster than SBA loans, though it still requires documentation like financial statements, tax returns, and a clear project scope.

This loan option is ideally suited for businesses with strong credit and an established banking relationship who want straightforward, lump-sum funding.

Business line of credit

A business line of credit works much like a credit card: you're approved for a maximum amount and can draw from it as needed, paying interest only on what you've actually borrowed. This makes it a particularly flexible option for office renovations that happen in phases or where final costs are still being refined.

What to know:

• Credit limits typically range from $10,000 to $1 million or more, depending on the lender and your business's financials.
• Most carry variable interest rates, which means your monthly costs may fluctuate with market conditions.
• Draw periods are commonly 12–24 months, after which you enter a repayment phase. Some lines are revolving, meaning you can borrow, repay, and borrow again.
• Lines of credit can be secured or unsecured. Secured lines tend to offer better rates and higher limits.

This loan option is ideally suited for office renovations with unpredictable costs, phased timelines, or smaller budgets—like remodeling a bathroom or refreshing a reception area—where you want the flexibility to draw funds incrementally rather than all at once.

Equipment financing

If a significant portion of your renovation involves purchasing new equipment—think HVAC systems, commercial-grade lighting, built-in AV setups, or large office furniture systems—equipment financing may cover those costs. The equipment itself serves as collateral, which can make approval easier and rates more competitive.

What to know:

• Loan terms typically match the expected useful life of the equipment, often 3–7 years.
• Down payments can be as low as 0–20%, depending on the lender and the equipment type.
• This won't cover general construction costs like demolition, electrical work, or interior buildout—it's specifically for equipment purchases.

This loan option is ideally suited for office renovations that include a major equipment component, especially when the business wants to keep its general credit lines open for other operational needs.

Short-term business loans and online lenders

For businesses that need funding quickly or don't meet the requirements of traditional bank or SBA programs, online lenders and alternative financing providers can fill the gap. These loans are typically unsecured, fund faster, and have less stringent qualification requirements—but they come at a higher cost.

What to know:

• Loan amounts commonly range from $5,000 to $500,000.
• Repayment terms are shorter—often 3 months to 5 years—with daily or weekly payments in some cases.
• Interest rates and fees can be significantly higher than bank or SBA products. Always review the APR (not just the stated rate) to understand the true cost of borrowing.
• Many online lenders can approve and fund within a few business days, making these a viable option when time is a factor.

This loan option is ideally suited for smaller office renovation projects where speed matters, or businesses that don't qualify for traditional lending products and need a shorter-term solution.

If you lease your office space

Many small businesses don't own their office—they lease it. If you're planning a fit out of a new space or renovating one you're already in, that changes the financing equation in a few important ways.

• Tenant improvement allowances (TIAs). Before looking at external financing, check your lease agreement. Many commercial landlords offer a tenant improvement allowance—a set amount of money (often quoted per square foot) that they'll contribute toward approved buildout work. TIAs are commonly negotiated at the start of a lease or at renewal, and they can significantly reduce how much you need to finance on your own. If your lease doesn't include one, it's worth asking—landlords have an incentive to invest in improvements that increase the property's long-term value.
• Leasehold improvement loans. Some lenders offer financing specifically for improvements to leased commercial spaces. These loans are typically secured by the improvements themselves or other business assets. Loan terms are usually aligned with the remaining length of your lease, so a shorter lease may limit your repayment window.
• SBA loans for leasehold improvements. SBA 7(a) loans can be used for leasehold improvements and office buildouts in leased spaces. The loan term for leasehold improvements is generally up to 10 years or matched to the remaining lease term, whichever is shorter.

A word on ownership of improvements. Improvements you make to a leased space typically become the landlord's property when the lease ends, unless your agreement says otherwise. Factor this into your financial planning—you want to make sure the investment makes sense for the duration you expect to occupy the space.

Tax considerations worth knowing about

Office renovations can carry meaningful tax implications, and understanding them ahead of time can influence both your financing strategy and your project timeline.

Qualified improvement property (QIP)

Interior improvements to nonresidential buildings—like new flooring, lighting, drywall, interior plumbing, and bathroom remodels—generally qualify as "qualified improvement property" under the tax code. Recent legislation has reinstated 100% bonus depreciation for QIP, which means you may be able to deduct the full cost of qualifying interior improvements in the year they're placed in service, rather than depreciating them over 15 years. This can have a significant impact on your tax bill in the year of your renovation, whether you're completing a full office fit out or a targeted remodel.

Interest deductibility

Interest paid on business loans is generally tax-deductible as a business expense, which can reduce the effective cost of borrowing. This applies to most of the financing products described in this guide, though the specifics depend on how the loan is structured and how the funds are used.

Important note: Tax rules are complex and change frequently. The information above is meant to flag considerations worth discussing with your accountant or tax adviso, not to serve as tax advice. Work with a qualified professional to understand how these provisions apply to your specific business.

How to choose the right financing for your office renovation

With multiple viable options, narrowing down your choice comes down to a few key questions about your business and your project.

• How large is the project? For renovations in the six-figure range, SBA loans or bank term loans typically offer the best combination of loan size, repayment terms, and interest rates. For smaller projects—refurbishing your office bathroom, updating a break room, or reconfiguring an open floor plan—a business line of credit or equipment financing may be more practical.
• Do you own or lease your space? Property owners have access to more financing options and may qualify for better terms because the property itself can serve as collateral. If you lease, start by reviewing your TIA options and consider SBA 7(a) or traditional business loans for the remainder.
• How quickly do you need the funds? SBA loans offer strong terms but require patience. If your renovation timeline is tight—say, you need to be operational in a new space within a few months—an online lender or business line of credit may get money in your hands faster.
• What does your cash flow look like? Be honest about how much your business can comfortably commit to monthly loan payments without straining operations. A longer repayment term means lower monthly payments but more total interest. Build contingency into your renovation budget (10–20% is a common recommendation) so that unexpected costs don't push your loan payments beyond what you can absorb.
• What's your credit profile? SBA and bank loans generally require a credit score of 680 or above and a strong financial track record. If your credit is still building or your business is relatively new, alternative lenders may be more accessible—just pay close attention to the total cost of borrowing.
