Lease Clauses That Shift Risk: CAM, Repairs, Assignment & Options

Contact Us Today

Posted by Porter Law Firm | Sep 3, 2026 | Real Estate

A commercial lease is a contract. Contracts allocate risk. Texas courts generally enforce these leases as written, especially between sophisticated parties. Therefore, the fine print controls who bears what risks. In commercial real estate transactions, this makes lease review as important as due diligence on the property itself.

Several common clauses quietly move high costs and rights from one side to the other. The sections below discuss these clauses in detail. 

Common Area Maintenance (CAM) Charges

In most retail and office leases, the tenant pays a share of the cost to operate and maintain shared areas, on top of base rent. In Texas, CAM can cover landscaping, parking lots, security, management fees, and more. 

Key protections to negotiate in such leases include::

  • A cap on annual CAM increases
  • A clear list of excluded expenses, such as capital improvements and the landlord’s financing costs
  • Limits on management and administrative fees
  • Audit rights to verify the landlord’s calculations

Without these protections, these charges can escalate year to year.

Repair and Maintenance Obligations

Texas recognizes an implied warranty that leased commercial space is suitable for its intended purpose, but that warranty can be waived through lease language. 

Repair clauses decide who pays when something breaks and needs repairs or maintenance. Under a triple-net lease, the tenant often takes on responsibility for the roof, structure, HVAC, and parking lot. An “as-is” clause can shift the condition of the premises entirely onto the tenant.

Tenants should confirm which systems they are responsible for and push to keep major structural and capital repairs with the landlord.

Assignment and Subletting

These clauses control whether a tenant can transfer the lease or bring in a replacement occupant. There are two common standards for landlord consent: 

  • “Consent not to be unreasonably withheld” gives the tenant flexibility
  • “Sole and absolute discretion” lets the landlord block any transfer

Two more provisions deserve attention. A recapture right lets the landlord take back the space instead of approving a transfer. 

A continuing-liability clause keeps the original tenant on the hook even after assigning the lease. Accordingly, a default by the new occupant becomes the original tenant’s problem.

Options – Renewal, Expansion, and Purchase

Options give a tenant valuable rights to extend, grow, or buy the leased property. Most of these rights depend on precise notice deadlines, meaning the tenant has to notify the landlord of their intent to renew, expand, or purchase within a specific timeframe. 

Common option provisions include:

  • Renewal options to extend the term, often at a set or market rate
  • Expansion options or a right of first refusal on adjacent space
  • A purchase option or right of first refusal to buy the property

Missing the notice window or sending a deficient notice can spoil a tenant’s options under the lease. That’s why it’s important to calendar every deadline and follow the lease’s exact delivery requirements.

Read the Risk Before You Sign

Each of these clauses can shift tens of thousands of dollars and key business rights from one party to the other. The best time to address them is during negotiation, not after a dispute. An experienced real estate attorney in Houston can help you understand the terms of your lease and what risks are allocated to each party.  

The attorneys at Porter Law Firm help Houston landlords and tenants negotiate the lease terms that satisfy their goals and protect their rights long-term. Call (713) 621-0700 to schedule a consultation.
