Commercial leases can vary significantly depending on the property type, location, tenant requirements, lease duration, and negotiating parties.

Common commercial properties include:

• Office buildings

• Retail centers

• Warehouses

• Industrial facilities

• Medical buildings

• Restaurants

• Mixed-use properties

• Professional offices

• Manufacturing facilities

Because lease provisions can create long-term financial and operational obligations, reviewing the agreement carefully before signing can help identify responsibilities, deadlines, risks, and potential areas requiring clarification.

What Is a Commercial Lease?

A commercial lease is a contractual agreement that generally gives a business the right to occupy and use specified property in exchange for agreed payments and compliance with stated terms.

A lease may establish:

• Premises

• Lease term

• Base rent

• Additional charges

• Security deposit

• Permitted use

• Maintenance responsibilities

• Insurance requirements

• Property access

• Improvements

• Assignment provisions

• Renewal rights

• Default provisions

• Termination conditions

The exact legal effect of each provision depends on the contract and applicable law.

Common Commercial Lease Structures

Commercial leases can be structured in different ways.

Gross Lease

Under a gross lease, the tenant generally pays an agreed rent while the property owner may remain responsible for specified operating expenses.

The exact expense allocation depends on the lease.

Net Lease

A net lease allocates certain property expenses to the tenant in addition to base rent.

Depending on the structure, these may include:

• Property taxes

• Insurance

• Maintenance

• Common-area expenses

Different net-lease structures can allocate expenses differently.

Percentage Lease

Percentage leases can combine base rent with an additional amount linked to the tenant's sales or another agreed measure.

This structure is commonly associated with certain retail arrangements.

Modified Gross Lease

A modified gross lease combines elements of gross and net structures.

The parties agree on which expenses are included in base rent and which are separately allocated.

Important Lease Terms

Before entering into a commercial lease, several provisions deserve careful review.

Lease Term

The term establishes how long the agreement remains in effect.

Important considerations can include:

• Commencement date

• Expiration date

• Renewal options

• Extension periods

• Notice deadlines

• Early termination rights

Base Rent

The agreement should clearly establish the initial rent and any scheduled changes.

Rent provisions may involve:

• Fixed increases

• Percentage increases

• Market-based adjustments

• Index-based adjustments

• Step-up schedules

The exact calculation method should be clearly documented.

Security Deposit

The lease may require a security deposit or another form of financial security.

The agreement should specify:

• Amount

• Permitted use

• Conditions for return

• Timing of return

• Requirements for replenishment

Local laws can affect how commercial security deposits are handled.

Tenant Responsibilities

Tenant responsibilities vary according to the lease.

Potential obligations can include:

• Paying rent

• Paying allocated operating expenses

• Maintaining the premises

• Maintaining business insurance

• Following property rules

• Obtaining required permits

• Maintaining fixtures or equipment

• Handling certain repairs

• Complying with applicable laws

• Keeping the premises in required condition

Responsibility for major structural components should be clearly identified rather than assumed.

Landlord Responsibilities

Depending on the agreement, the property owner may remain responsible for:

• Structural components

• Common areas

• Building systems

• Certain repairs

• Property insurance

• Property taxes

• Building compliance

• Exterior maintenance

The actual allocation depends on the lease structure and negotiated terms.

Operating Expenses and Common-Area Charges

Commercial tenants may be responsible for some portion of property operating expenses.

These can include:

• Property taxes

• Building insurance

• Utilities

• Landscaping

• Security

• Cleaning

• Repairs

• Common-area maintenance

• Property management

• Snow or grounds maintenance where applicable

A lease should identify how these expenses are calculated and allocated.

For tenants paying a proportionate share of expenses, it can be useful to understand the calculation method, expense categories, exclusions, audit rights, and documentation requirements.

Maintenance and Repair Responsibilities

Maintenance provisions can create significant obligations.

The lease should identify responsibility for:

• HVAC systems

• Plumbing

• Electrical systems

• Roof

• Structure

• Windows

• Doors

• Interior finishes

• Parking areas

• Common areas

• Building equipment

Some leases divide responsibilities based on whether the repair involves routine maintenance, major replacement, structural components, or tenant-specific equipment.

Insurance Requirements

Commercial leases frequently contain insurance provisions.

Potential requirements can involve:

• General liability insurance

• Property insurance

• Workers compensation insurance

• Business interruption coverage

• Automobile insurance

• Additional insured provisions

The required limits and coverage types depend on the property, tenant activities, lease provisions, and applicable law.

Tenants should review whether their existing insurance arrangements satisfy the lease requirements before occupancy.

Permitted Use and Zoning

The permitted-use clause identifies how the tenant may use the premises.

This can be important because a business may require:

• Specific zoning authorization

• Health permits

• Building approvals

• Fire approvals

• Environmental permits

• Accessibility compliance

• Industry-specific licenses

A tenant should verify that the intended business activity is permitted at the property before entering into a long-term lease.

Improvements and Buildouts

Tenants may want to modify the premises before or during occupancy.

Potential improvements can include:

• Interior partitions

• Flooring

• Lighting

• Electrical upgrades

• Plumbing

• Signage

• Specialized equipment

• Accessibility modifications

• HVAC changes

The lease should clarify who pays for improvements, who owns installed items, what approvals are required, and whether the tenant must restore the premises when the lease ends.

Assignment and Subleasing

Businesses can change ownership, structure, or operational requirements during a lease term.

Assignment and subleasing provisions determine whether the tenant can:

• Transfer the lease

• Sublease part of the premises

• Transfer the business

• Change ownership

• Bring in another occupant

The lease may require the property owner's written approval or establish specific conditions for a transfer.

Default and Remedies

A commercial lease generally establishes what happens if one party fails to meet its obligations.

Potential default events can include:

• Unpaid rent

• Failure to maintain required insurance

• Unauthorized use

• Unauthorized alterations

• Breach of other material obligations

The agreement may specify:

• Notice periods

• Cure periods

• Late charges

• Remedies

• Termination rights

• Recovery of certain expenses

Because default provisions can have significant consequences, they should be reviewed carefully.

Property Risks

Commercial lease planning should consider risks beyond rent.

Potential property-related risks include:

• Building defects

• Water intrusion

• Fire

• Environmental contamination

• Utility interruptions

• Security incidents

• Equipment failure

• Flood exposure

• Accessibility issues

• Regulatory changes

• Major capital repairs

The allocation of responsibility for these risks should be clear in the lease and related documents.

Environmental and Building Considerations

Depending on the property and business activity, due diligence may involve environmental or building assessments.

Potential considerations include:

• Hazardous materials

• Previous industrial activity

• Mold or moisture

• Asbestos-containing materials

• Underground storage tanks

• Structural conditions

• Electrical capacity

• HVAC capacity

• Fire-protection systems

The appropriate investigation depends on the property's history, intended use, location, and transaction.

Commercial Lease Legal Review

A commercial lease can contain numerous legal provisions that affect the parties' obligations.

Areas commonly reviewed by legal professionals include:

• Liability

• Indemnification

• Insurance

• Default

• Remedies

• Renewal

• Assignment

• Subleasing

• Personal guarantees

• Dispute resolution

Conclusion

A careful review can help identify responsibilities and potential obligations before they become operational or financial issues.

Because commercial leasing laws and contract requirements vary by jurisdiction and property type, significant lease decisions should be based on the actual agreement, current local requirements, and appropriate professional guidance.
