Whether you are signing your first office lease or acquiring a commercial building to house your growing operation, commercial real estate transactions carry legal and financial consequences that can follow your business for decades. The agreements you sign today will define your occupancy costs, your flexibility, and your liability for years to come. Understanding what you are signing and what you are not getting is essential before you commit.

Leasing vs. Buying: Choosing the Right Path for Your Business

The first decision is structural: should your business lease commercial space or purchase it outright? Both paths have legitimate advantages, and the right answer depends on your capital position, growth trajectory, and long-term plans.

Leasing preserves capital and maintains flexibility. If your business is scaling quickly or if you are not yet certain about your space needs, a lease lets you commit to a location without tying up equity that might be better deployed in operations or growth. The tradeoff is that you have no ownership stake and are subject to renewal uncertainty and rent escalations over time.

Purchasing commercial property builds equity, provides stability, and can generate income if you occupy only part of the building. However, it requires significant capital, subjects you to property maintenance obligations, and reduces your flexibility to relocate. Many business owners choose to hold commercial property in a separate LLC or holding entity rather than in the operating business, which provides important liability insulation and estate planning benefits.

Our commercial real estate practice helps business owners evaluate both options and structure ownership in a way that protects the business long-term.

Critical Commercial Lease Terms to Negotiate

Commercial leases are not consumer contracts. There is no standard form, and landlords present them as non-negotiable as a matter of course. In practice, most terms are negotiable if you know what to ask for. The following provisions deserve careful attention before you sign.

Rent escalations and rent abatement. Most commercial leases include annual rent increases tied to a fixed percentage or CPI index. Understand exactly what you are agreeing to and model the total occupancy cost over the full lease term, not just the starting rate. In competitive markets, you can often negotiate free rent for the first several months as a build-out concession. Get it in writing and make sure the language is unambiguous.

Common Area Maintenance (CAM) charges. In triple-net (NNN) leases, you pay your proportionate share of the building's common area maintenance, property taxes, and insurance on top of base rent. CAM charges can add 20 to 40 percent to your stated rent figure. Negotiate a cap on annual CAM increases, audit rights, and clear definitions of what is and is not includable. Exclude capital improvements and management fees from CAM whenever possible.

Tenant Improvement (TI) allowance. If the space requires build-out to suit your business, negotiate a tenant improvement allowance that the landlord will contribute toward construction. Understand whether the allowance is paid in advance or as reimbursement, and what happens to improvements at lease end. Make sure the lease is clear about ownership of fixtures and specialized equipment installations.

Assignment and subletting rights. Circumstances change. You need the ability to assign your lease or sublet your space if you sell the business, need to downsize, or change locations. Many leases require landlord consent for assignment, which is reasonable, but negotiate for a standard of not to be unreasonably withheld and a clear timeframe for the landlord's response. Our contracts practice regularly negotiates these provisions to ensure clients are not locked into space without a practical exit.

Exclusivity clauses. If you operate a retail or service business, consider negotiating an exclusivity provision preventing the landlord from leasing other space in the building or center to a direct competitor. The scope and duration of exclusivity provisions require careful drafting to be enforceable and meaningful.

Renewal and expansion options. Lock in your right to renew before you sign the initial lease. Specify the rent for any renewal term or the mechanism to determine it. If there is adjacent space you might need as you grow, negotiate a right of first offer or right of first refusal on that space now.

Due Diligence When Buying Commercial Property

Purchasing commercial real estate requires thorough due diligence before closing. Gaps in due diligence can expose you to environmental liability, title defects, zoning problems, and undisclosed physical conditions that may cost you significantly after the deal is done.

Title and survey. Order a title commitment early in the process and review it carefully for easements, encumbrances, liens, and restrictive covenants. Many commercial properties carry easements that significantly affect how you can use the land. A current ALTA survey will reveal boundary issues, encroachments, and easement locations that a title commitment alone will not show you.

Environmental assessment. A Phase I Environmental Site Assessment is standard in commercial acquisitions. It reviews historical records and site conditions for evidence of contamination or environmental concern. If Phase I identifies recognized environmental conditions, a Phase II assessment with soil and groundwater sampling may be required. Environmental liability can be severe and does not automatically follow prior ownership, so never skip this step regardless of how clean the property appears.

Zoning and land use compliance. Confirm that the property is zoned for your intended use before closing. Review any conditional use permits, variances, or special exceptions that apply to the property, and determine whether they are transferable to a new owner. Contact the local planning and zoning department directly. Zoning issues discovered after closing can prevent you from using the property as planned and are expensive to resolve.

Physical condition inspections. Commission a commercial building inspection covering the roof, HVAC systems, plumbing, electrical, foundation, and structural components. For specialized uses like food service or manufacturing, engage the appropriate trades for specific system reviews. The cost of a thorough inspection is trivial compared to the repair costs it can uncover.

If you are acquiring a property with existing tenants, review all leases in place, confirm rent rolls, verify security deposits, and assess the quality of the tenant base. Existing contractual obligations run with the property and transfer to you as the new owner at closing.

Structuring the Acquisition Correctly

How you take title to commercial property matters. Holding real estate in a separate entity from your operating business is generally advisable. If the operating business faces a lawsuit or creditor claim, property held in a separate LLC is insulated from those claims, provided the structure is maintained properly. The reverse is also true: if the property LLC carries debt or incurs liability, the operating company is protected.

Your financing structure will also affect your entity options. Lenders have preferences and requirements about how title is held, and some loan structures affect your ability to transfer or refinance later. Work through the entity structure with both your attorney and your accountant before closing. For businesses in the real estate industry, the intersection of tax planning and legal structuring is where the most value is created and preserved.

Common Mistakes Business Owners Make in Commercial Real Estate

The most common mistake is signing a long-term lease or purchase agreement without legal review. Commercial real estate documents are complex, heavily landlord-favorable or seller-favorable in their standard form, and binding for the full stated term. A few hours of attorney review before signing can save years of unfavorable obligations.

The second most common mistake is focusing only on the base rent or purchase price without understanding the total cost of occupancy. For leases, that means modeling base rent, CAM charges, utilities, insurance, and build-out amortization over the full term. For purchases, it means accounting for property taxes, maintenance reserves, debt service, and opportunity cost on the deployed capital.

A third common error is failing to negotiate the personal guarantee provisions. Landlords typically require business owners to personally guarantee commercial leases, meaning your personal assets are exposed if the business fails. Negotiate a burn-down provision so the personal guarantee diminishes after a period of good payment history, or cap the guaranteed amount at a fixed dollar figure.

Get Legal Counsel Involved Early

The best time to involve a commercial real estate attorney is before you are committed to a space or a property. Once you are emotionally invested in a deal, your negotiating position weakens. Getting counsel involved at the letter of intent stage allows you to shape the key deal terms before the formal documents are drafted, which is far more efficient than trying to renegotiate a completed lease or purchase contract.
