Most commercial lease disputes don't start with a disagreement. They start with a signature - on a document the tenant didn't fully understand at the time.

In Orange County's commercial real estate market, business owners are often under pressure to move quickly. A good space gets multiple offers. Brokers push for fast decisions. And lease agreements - sometimes 30, 40, or 50 pages long - get glossed over in the rush to get the keys.

This guide walks through what experienced commercial real estate attorneys look for before a lease is signed, so you know what questions to ask and what to watch out for before you commit.

The Orange County Commercial Lease Landscape

Orange County has one of the more competitive commercial real estate markets in Southern California. From Irvine's business parks to retail corridors in Anaheim, Santa Ana, and Newport Beach, lease terms vary significantly depending on the submarket, property type, and landlord.

That variation matters. A lease in a Class A Irvine office park is going to look very different from one in a light industrial space in Fullerton or a retail strip in Mission Viejo. Local conditions affect everything from base rent and CAM structures to how aggressively landlords negotiate tenant improvement allowances.

Understanding where you're leasing - not just what you're leasing - is part of making a sound decision.

What to Review Before You Sign

1. The Rent Structure (It's Rarely Just "The Rent")

The base rent number is usually what gets discussed. It's rarely the whole story.

Most commercial leases in California include additional rent obligations layered on top of the base figure. Common area maintenance (CAM) charges, property taxes, and insurance costs are frequently passed through to tenants - sometimes in ways that aren't obvious until the first reconciliation statement arrives.
Ask for a full breakdown of estimated total occupancy costs before you sign. A $4,000/month base rent on a triple net lease can easily cost $5,500 or more per month once all pass-throughs are factored in.

Also review how CAM charges are calculated, whether they're capped, and what's actually included. "Administrative fees" added on top of actual CAM expenses are common and negotiable.

2. Maintenance and Repair Responsibilities

This is one of the most litigated areas in commercial leasing, and one of the most misunderstood.

Many tenants assume the landlord handles building repairs. Many landlords assume the tenant does. What actually controls is the lease language - and it doesn't always match either party's expectations.

Pay close attention to clauses covering:

• HVAC systems (who maintains them, who replaces them if they fail)
• Roof and structural elements
• Plumbing and electrical systems
• Exterior areas and parking lots

In Orange County, it's not uncommon to see leases that place HVAC maintenance and even replacement squarely on the tenant. If you're leasing a freestanding building, you may be responsible for far more than you'd expect. Read these sections carefully - and if the language is ambiguous, get it clarified in writing before signing.

3. Permitted Use Clauses

Every commercial lease defines what the space can be used for. That definition matters more than most tenants realize.

A permitted use clause that's too narrow can prevent you from adding services, changing your business model, or subletting to a buyer if you ever want to sell your business. A clause that's too broad can create landlord pushback or conflicts with other tenants in a multi-tenant building.

Before you sign, make sure the permitted use clause accurately reflects not just what you do today, but what you might reasonably need to do in the next five to ten years.

4. Lease Term, Renewal Options, and Exit Rights

Long-term leases offer rent stability. They also lock you in.

For a business in growth mode - or one that might need to scale back - flexibility has real value. Before committing to a five or ten-year term, consider:

Renewal options: Does the lease include options to renew, and at what rent? "Fair market value" renewal terms sound reasonable but can lead to disputes when renewal time comes and you and the landlord have very different views of what the market supports.

Early termination rights: Some leases include termination clauses that allow a tenant to exit with sufficient notice and payment of a termination fee. These provisions are negotiable upfront and much harder to add later.

Assignment and subletting: If there's any chance you'll want to sell your business, bring in a partner, or exit the space before the lease ends, review the assignment and subletting provisions carefully. Landlord consent requirements vary, and some leases give landlords broad rights to withhold approval or recapture the space.

5. Tenant Improvement Allowances

If the space needs buildout work, negotiate the tenant improvement (TI) allowance before signing - not after.

Landlords in competitive Orange County submarkets will often offer TI allowances to attract quality tenants, but the terms matter. Understand what the allowance covers, what approval process is required, who controls construction, and what happens if your buildout costs exceed the allowance.

Also review the lease provisions around alterations and improvements at the end of the term. Some leases require tenants to remove improvements and restore the space to its original condition - a cost that can be significant depending on what was built out.

6. Zoning and Conditional Use Permits

Before signing any lease, verify that the property is properly zoned for your intended use.

In Orange County, zoning compliance involves both the municipal code for the city where the property is located and, in some cases, county or regional planning requirements. A property that looks right for your business may require a conditional use permit (CUP) that takes months to obtain - or may not be approvable at all.

If your ability to operate depends on a CUP or other entitlement, make sure the lease is conditioned on obtaining that approval, or that you have the right to terminate if approval isn't granted within a defined period.

7. ADA Compliance Responsibilities

The Americans with Disabilities Act imposes accessibility requirements on commercial properties, and lease language determines who is responsible for compliance.

In California, accessibility requirements under the ADA are supplemented by state law - including the Unruh Civil Rights Act and California Building Code - which in some cases impose stricter standards than federal law. Exposure from ADA-related claims in California can be significant.

Review your lease to understand who bears responsibility for ADA compliance, particularly for common areas, parking, and building access. If the landlord is representing that the property is compliant, get that in writing and consider what recourse you have if that turns out not to be the case.

8. Insurance Requirements

Commercial leases typically require tenants to maintain certain insurance coverages, including general liability and sometimes property insurance. Review these requirements carefully before signing.

Common issues include:

• Coverage limits that are higher than standard policies provide
• Requirements to name the landlord as an additional insured
• Provisions that may conflict with your existing business insurance

Bring the insurance requirements from any lease you're seriously considering to your insurance broker before signing. Gaps or mismatches in coverage are much easier to address before you've committed to the lease.

Red Flags Worth Slowing Down For

Not every lease issue is a dealbreaker, but some provisions warrant a harder look before proceeding:
No cap on CAM charges. Without a cap, your occupancy costs can increase significantly year over year.
Landlord termination rights. Some leases include provisions allowing the landlord to terminate early under certain conditions. Understand the circumstances under which this could happen and what notice and compensation you'd receive.
Personal guarantees. Many commercial landlords require a personal guarantee from the business owner, making you personally liable for the full term of the lease if the business can't perform. Understand what you're guaranteeing and whether it's negotiable.
Relocation clauses. In multi-tenant buildings, some leases allow the landlord to relocate your business to a different space. If this provision exists, make sure it includes meaningful protections - advance notice, comparable space, and reimbursement of your moving costs at minimum.

The Cost of Signing Too Fast

A commercial lease is typically one of the largest financial commitments a small business makes. A five-year lease at $6,000 per month is a $360,000 obligation - and that's before accounting for CAM charges, buildout costs, or personal guarantee exposure.

The time it takes to review the lease carefully, ask the right questions, and negotiate terms that reflect your actual needs is almost always well spent. Problems that surface before signing are negotiating points. Problems that surface after signing are disputes.
