Commercial Construction Business Loans: Fund the Build Without Funding Delays

What Is a Commercial Construction Business Loan?

A commercial construction business loan is a draw-based financing product that releases funds in stages as your project reaches defined milestones, rather than depositing the full amount at closing.

During the construction phase, you pay interest only on the outstanding drawn balance, which keeps your monthly carrying costs low while the building is still being completed.

Each draw is tied to an approved budget line item, and the lender typically requires an inspection before releasing each payment to verify that the work matches the claimed progress.

Once construction is finished, the loan either converts to permanent financing or you refinance it with a commercial mortgage, effectively replacing the short-term construction note with a standard amortizing loan.

Loan Types: Ground-Up vs. Tenant Improvement vs. Build-Out

Commercial construction financing isn't a single product — it covers three distinct project categories that differ in loan size, risk, and draw structure.

Ground-Up Construction

Ground-up loans finance new commercial buildings from bare land through certificate of occupancy, making them the largest and most complex type of commercial construction financing.

Lenders typically require 20–35% equity in the project and want to see a licensed general contractor, a detailed construction budget, and evidence that you have a tenant or buyer committed to the finished building.

Tenant Improvement Loans

Tenant improvement (TI) loans fund leasehold build-outs where a business is customizing rented commercial space, covering everything from HVAC and electrical work to demising walls and custom millwork.

These loans can fund up to 90% of the TI budget in some cases and often disburse in a single payment or two to three draws given that the project scope is smaller and more predictable.

Commercial Build-Out Financing

A commercial build-out loan sits between a TI loan and ground-up construction, typically financing the expansion or major renovation of an existing commercial property.

It's a good fit when you own the property and need to add square footage, reconfigure an existing space, or upgrade systems across a larger footprint than a standard TI project.

Draw Schedules and How Lenders Disburse Funds

A draw schedule is the contractual roadmap that defines exactly when money moves from your construction loan to your contractor, linking each disbursement to a verified stage of completed work.

Most commercial construction projects use four to six draws, with larger or more complex builds sometimes requiring eight or more disbursements to keep funds closely aligned with verified progress.

How Inspections Protect Both Sides

Before releasing any draw, the lender sends a third-party inspector to confirm that the work described in the draw request has actually been completed and matches the approved budget line items.

This inspection step typically adds two to five business days to the draw timeline, so building that lag into your contractor payment schedule helps avoid delays at the job site.

Interest-Only Construction Payments

You're charged interest only on the drawn balance during construction, which means your monthly payment grows gradually as more funds are released over the project timeline.

Early draws on a $2 million loan might generate monthly interest of only a few thousand dollars, while payments near project completion approach the full loan balance carrying cost.

Qualifying for a Commercial Construction Loan

Lenders approving commercial construction loans look harder at your experience and project feasibility than they do for a standard commercial mortgage, because an unfinished building is difficult collateral to liquidate.

Expect the underwriter to evaluate your personal credit, your construction track record, the quality of your contractor, and the financial reserves you have to handle cost overruns.

Credit and Financial Requirements

Most commercial construction lenders want a personal credit score of 680 or above, though community banks and credit unions sometimes go to 660 for borrowers with strong project experience and substantial equity.

You'll also need to show two to three years of business financial statements and demonstrate that you have the income to service the permanent loan once construction is complete.

Down Payment and Reserves

A down payment of 20 to 30% of total project cost is standard, and lenders will want to see cost overrun reserves of 10 to 15% on top of that amount sitting in a controlled account.

Those reserves protect the lender if material costs spike or the project runs long, and they're often a hard requirement rather than a soft preference.

Contractor and Project Feasibility

Your general contractor needs a current license, bonding, and a documented history on similar-scale commercial projects before most lenders will approve the construction loan.

The lender will also review your plans and specs, your building permits, and a third-party appraisal of the completed project value to confirm that the loan-to-cost and loan-to-value ratios make sense.

Lender Options and Rate Ranges

The lender type you choose for a commercial construction loan directly determines your rate, closing speed, documentation requirements, and how much flexibility you'll have during the build.

Community banks typically offer the best rates in the 7.5 to 9.5% range but move slowly, while hard money lenders close fast at 10 to 14% for borrowers who need speed over cost.

Community Banks and Credit Unions

Community banks and credit unions are the preferred source for commercial construction financing because they hold the loan in-house and can customize draw schedules and terms to fit your project's specific needs.

The trade-off is a slower approval process, often 45 to 90 days, and a strong preference for borrowers who already have a banking relationship with the institution.

SBA CDC/504 for Owner-Occupied Projects

The SBA 504 program is a strong option if you'll occupy at least 51% of the finished building, offering loan-to-cost ratios up to 90% with below-market fixed rates on the CDC portion.

Construction with SBA 504 requires working with both a conventional lender and a Certified Development Company, which adds complexity but dramatically reduces your down payment requirement.

Hard Money and Private Construction Lenders

Hard money construction lenders close in as little as 10 to 21 days and will often approve projects that banks won't touch, such as speculative builds or borrowers with credit issues.

Rates typically run 10 to 14% with origination points of 2 to 4%, so the cost premium is real and this option works best when speed or approval probability matters more than rate.

Life Insurance Companies

Life insurance companies are an underutilized source for larger commercial construction projects above $5 million, often offering competitive fixed rates for high-quality, pre-leased assets.

They're known for conservative underwriting and slow decision-making, but the rate and term combination can outperform what banks offer on large stabilized construction projects.

Construction-to-Permanent Loan Conversion

A construction-to-permanent loan solves the most stressful moment in any build project: how you refinance out of the construction note when the building is done.

You have two paths: a one-close loan that bakes both phases into a single transaction, or a two-close structure that treats construction and permanent financing as separate loans.

One-Close Construction-to-Perm Loans

With a one-close loan, you sign all documents at the initial closing and the loan automatically converts to permanent financing once a defined trigger event occurs, usually the issuance of a certificate of occupancy.

The main advantage is cost savings and certainty — you pay one set of closing costs and you've already locked your permanent rate terms, so rising rates during construction don't threaten your exit strategy.

Two-Close Construction Loans

A two-close structure requires a separate closing when you're ready to convert to permanent financing, which gives you the chance to shop rates after the building is complete and operating.

That flexibility comes with a cost: two sets of closing fees, additional underwriting, and the risk that lending conditions tighten between your construction close date and your permanent close date.

Mini-Perm and Rate Lock Considerations

A mini-perm loan is a short-term permanent loan, typically three to five years, that replaces the construction note and gives you time to stabilize occupancy before refinancing to a long-term commercial mortgage.

Rate lock agreements on one-close construction loans often come with float-down provisions that let you capture a lower rate if markets improve during the construction period, which is worth negotiating when you're in a falling-rate environment.
