What Arizona Business Owners Should Know Before Signing a Commercial Lease

By Roman A. Kostenko June 30, 2025

For Arizona business owners, signing a commercial lease is a pivotal moment. Whether you're opening your first storefront, relocating your office, or expanding into a new market, the lease you sign will shape your business’s financial obligations, operational flexibility, and legal exposure for years to come.

Unlike residential leases, commercial leases are not standardized. They are complex, negotiable contracts that often favor the landlord. Without a thorough legal review, business owners may unknowingly agree to terms that are financially burdensome, legally risky, or operationally restrictive.

At Arizona Legal Advisor, we help business owners across the state understand, review, and negotiate commercial leases that align with their goals and protect their investments. This guide outlines what every Arizona business owner should know before signing on the dotted line.

Why Commercial Lease Review Is Essential

Many business owners assume that lease terms are “take it or leave it.” In reality, most commercial leases are negotiable — especially when you understand the leverage points. A lease that seems straightforward may contain:

  • Hidden costs buried in legal language

  • Unfavorable clauses that limit your ability to grow or relocate

  • Broad personal guarantees that put your personal assets at risk

  • Ambiguities that can lead to disputes or litigation

Key Lease Terms Every Arizona Business Owner Should Understand

1. Rent and Escalation Clauses

  • Flat monthly rent vs. rent based on square footage

  • Escalation clauses tied to annual increases or CPI

  • Base year provisions in modified gross leases

2. Lease Structure: NNN, Gross, or Modified Gross

  • Triple Net (NNN): Tenant pays rent + taxes, insurance, maintenance

  • Gross Lease: Landlord covers most expenses

  • Modified Gross: Shared costs—terms vary

3. Lease Term and Renewal Options

  • Initial term (3, 5, or 10 years)

  • Renewal options and rent adjustments

  • Exit flexibility and expansion rights

4. Personal Guarantees

  • Landlords may require personal liability

  • Negotiate caps, time limits, or “good guy” clauses

5. Tenant Improvements (TIs)

  • Who pays for build-outs?

  • Approval process and ownership after lease ends

6. Common Area Maintenance (CAM) Fees

  • Costs for shared areas like lobbies and parking

  • Fee calculation, caps, and audit rights

7. Use Clauses and Exclusivity

  • Define permitted business activities

  • Seek exclusivity to block competitors

8. Assignment and Subletting

  • Can you assign the lease or sublet?

  • Important for business sale or relocation

9. Insurance and Indemnity Requirements

  • Understand required coverage types and limits

  • Review indemnity clauses carefully

Common Pitfalls to Avoid

  • Accepting boilerplate lease language

  • Overlooking hidden costs like CAM or tax increases

  • Agreeing to unlimited personal guarantees

  • Failing to negotiate renewal or exit terms

  • Relying on verbal promises not in writing

How Legal Review Protects Your Business

  • Spot red flags and unfavorable terms

  • Translate legal jargon into plain English

  • Negotiate revisions aligned with your goals

  • Prevent misunderstandings and litigation

Negotiation Tips for Arizona Business Owners

  • Take your time—don’t rush into signing

  • Ask questions and seek clarification

  • Negotiate rent, escalation, and guarantees

  • Plan for growth and document everything

Industry-Specific Considerations

  • Retail: signage rights, visibility, exclusivity

  • Medical: build-outs, HIPAA compliance

  • Restaurants: ventilation, grease traps, hours

The Role of Due Diligence

  • Check zoning laws and permitted uses

  • Inspect building condition and code compliance

  • Research landlord reputation

Conclusion: A Smart Lease Is a Strategic Asset

Your commercial lease is more than a monthly expense—it’s a foundational part of your business strategy. With proper legal guidance, you can:

  • Understand your rights and obligations

  • Negotiate terms that support your growth

  • Avoid costly disputes and legal entanglements
