A commercial lease is one of the largest financial commitments your business will make. Unlike investors who can refinance or sell, tenants are bound to the terms they sign, often for five to ten years. The steps below are written specifically for tenants: companies leasing office, industrial, lab or flex space for their own operations. Each one is designed to surface risks before they become obligations, and to give you negotiating leverage before you’re locked in.
1. Understand What You’re Actually Agreeing To: Lease Structure and Key Terms
Before anything else, read the full lease, and have an attorney experienced in commercial tenant representation read it alongside you. Commercial leases are written by landlord counsel, which means the defaults favor the landlord. Understanding lease structure means knowing whether you’re signing a gross lease (landlord covers operating expenses) or a net lease (you pay some or all of them), and what the practical cost difference is over your full term.
Key terms every tenant should scrutinize before signing:
- Base rent and escalation schedule: How much does rent increase annually, and is it capped or tied to CPI?
- Operating expense pass-throughs: What expenses can the landlord bill back to you, and are they capped?
- Permitted use clause: Does it describe your actual operations specifically enough to protect you if your business evolves?
- Assignment and sublease rights: Can you transfer the lease or sublet space if your needs change?
Hughes Marino’s in-house legal team typically conducts a parallel lease review on every transaction for our advisors’ benefit, specifically to identify clauses that look standard but carry real financial exposure for tenants. Our clients can then share our suggestions with their own legal counsel.
2. Verify Ownership, Title and Encumbrances From a Tenant’s Perspective
You may not be buying the property, but who owns it and how it’s encumbered still matters enormously to you as a tenant. A landlord in financial distress, a property subject to a deed of trust with a lender who hasn’t agreed to recognize your lease, or an ownership dispute mid-term can disrupt your occupancy rights even when you’ve paid every dollar of rent on time.
Request a current title report and review it for:
- Existing liens or mortgages, and whether a Subordination, Non-Disturbance and Attornment (SNDA) agreement is in place to protect your tenancy if the lender forecloses
- Easements that could restrict your access, signage or parking
- Ownership structure is the entity signing the lease the actual title holder?
Why this matters for tenants: Negotiating an SNDA before you sign is one of the most important protections a commercial tenant can secure. Without it, a lender who forecloses on the building has no obligation to honor your lease, even if you’ve never missed a payment.
3. Inspect the Physical Space and Know Who Pays for What You Find
A property condition assessment isn’t just for buyers. As a tenant, understanding the condition of the building’s systems, including HVAC, plumbing, electrical and roof, determines whether you’ll face surprise capital requests, service interruptions or lease clauses that make building deficiencies your problem.
Before signing, tenants should:
- Commission an independent inspection of the premises and building systems. Do not rely solely on landlord disclosures.
- Clarify in the lease exactly which maintenance and repair obligations fall on the tenant versus the landlord, and push back on any clause that shifts major capital repairs (roof, structure, HVAC replacement) onto the tenant.
- Understand the age and expected lifespan of critical systems, especially in older buildings, so you can negotiate repair obligations and TI allowances accordingly.
- For industrial, lab or specialized spaces, engage engineering consultants to assess infrastructure specific to your operational needs: power capacity, floor load ratings, ventilation and specialized utility requirements.
4. Conduct Environmental Due Diligence: Your Liability Starts the Day You Sign
Environmental issues are not just a buyer’s problem. Tenants who occupy contaminated sites can face regulatory scrutiny, operational restrictions and reputational exposure, even when the contamination predates their occupancy. A Phase I Environmental Site Assessment (ESA) is standard practice before leasing, particularly for industrial, manufacturing or lab spaces where prior tenants may have left behind hazardous materials. In 2026, energy performance matters too. Not just for corporate compliance but for your occupancy costs. An energy-inefficient building means higher utility bills that often flow through to tenants via operating expense pass-throughs.
Tenants should request the building’s historical operating expense statements, not just the landlord’s projections. Actual utility cost history reveals what you should roughly expect to pay, and gives you grounds to negotiate pass-through caps before you’re locked in.
5. Analyze the Full Financial Picture: Net Effective Rent, Not Just Face Rent
This is where most tenants undersell themselves. The face rent quoted on a space is not what you’re actually paying. Net effective rent, which accounts for free rent periods, tenant improvement allowances and escalations over the full lease term, is the only accurate basis for comparing competing options.
What tenants should model before committing:
- Net effective rent across each option, accounting for all concessions and escalations over the full term.
- Total occupancy cost including base rent, NNN charges, parking, utilities and any tenant-paid capital items.
- TI allowance adequacy: Does the landlord’s offered allowance actually cover your buildout, or will you be funding the gap out-of-pocket?
- Break-even timeline: How long before the economics of this space are favorable, accounting for moving costs and any overlap with your current lease?
Upon request, Hughes Marino’s advisors can financially model multiple scenarios for every transaction, translating complex lease structures into a total cost comparison that gives tenants a clear, defensible basis for negotiation.
6. Scrutinize Every Lease Clause That Limits Your Flexibility
Lease clauses that seem minor at signing can become significant constraints as your business evolves. This is the due diligence step most tenants underestimate, and where landlord-drafted agreements consistently work against tenant interests.
| Clause | What to Watch For | What to Push For |
| Renewal options | Market-rate renewals with no floor protection | Fixed rate or capped FMV renewal with adequate notice window |
| Assignment/sublease | Landlord consent at sole discretion; profit-sharing clause | Reasonable consent standard; no landlord profit participation |
| Contraction rights | None included by default | Right to give back 10–25% of space with advance notice |
| Operating expense caps | Uncapped controllable expense pass-throughs | Annual cap of 3–5% on controllable expenses |
| Exclusive use | Not included | Exclusive use clause matching your core business activity |
| Personal guarantee | Full personal guarantee on all obligations | Cap guarantee to 12–18 months of rent obligations |
Hughes Marino’s in-house lease audit process can help flag these provisions before negotiation begins, turning hidden landlord advantages into items the tenant team addresses before ink hits paper.
7. Benchmark the Deal Against the Market: Trust the Process, Not Landlord Narratives
One of the most important protections a tenant has in lease negotiation is leveraging the market. Landlords price space to their advantage and will routinely cite “market rate” oftentimes providing market “comps” as the ultimate arbiter. Your due diligence should include an independent analysis of what alternative buildings owners will concede for your occupancy rather than a manipulated backwards dated, often irrelevant “comp” that has hundreds of variables, including poor or conflicted tenant leasing representation.
What proper market leverage should cover:
- Finding 3-5 alternative buildings to consider.
- Evaluate space efficiencies for each option, as one or more may be much more efficient and provide for taking less space without compromising workflow.
- Evaluate term, rental rates, operating expenses, parking charges, etc.
- Evaluate concession packages (TI allowances, free rent periods) that comparable tenants are receiving
- Vacancy rates and absorption trends that indicate whether negotiating leverage is shifting toward tenants or landlords
- New construction pipeline that could affect future supply and rental rates
Tenants who “trust the process” to understand their value in the marketplace negotiate from a position of knowledge. Those who don’t negotiate from the landlord’s narrative and framing.
8. Review Code Compliance and Building Certifications: Know What’s Already Your Responsibility
Code compliance matters to tenants because deficiencies in leased premises can become the tenant’s financial burden, depending on how the lease is drafted. A landlord who delivers a space with an open permit, outdated ADA compliance gaps or deferred life-safety work may have drafted the lease to pass those costs to the tenant through maintenance obligations or improvement requirements.
Before signing, tenants should:
- Confirm that the space has a current certificate of occupancy for the intended use
- Identify any open permits or code violations on the property, which can delay your buildout or trigger retrofits at your expense
- Review ADA compliance for the premises and confirm who bears responsibility for any required upgrades
- For California tenants: assess seismic compliance status and any retrofit requirements applicable to the building
- Ask whether any building system upgrades are needed to support your intended use, and negotiate the cost allocation clearly in the lease before signing
9. Assess Risk Allocation: Insurance, Security and What Happens When Things Go Wrong
Insurance requirements in commercial leases are a frequent source of hidden cost and risk for tenants. Landlords commonly require tenants to carry specific coverage types and limits, name the landlord as an additional insured and waive subrogation rights. These are all provisions that affect your insurance costs and your ability to recover losses.
Tenant insurance review checklist:
- What are the lease’s minimum coverage requirements? Are they proportionate to your actual risk exposure?
- Does the lease contain a mutual waiver of subrogation, limiting your ability to recover from the landlord for certain damages?
- What does the landlord’s own insurance cover, and where does tenant liability begin?
- For multi-tenant buildings: how are common area liability claims handled?
Beyond insurance, evaluate the building’s physical security, especially for businesses handling sensitive data, client information or valuable inventory. Assess access control, surveillance and any physical security provisions the lease does or does not guarantee.
10. Align the Lease with Your Business Trajectory: Not Just Your Current Needs
The most common due diligence failure isn’t missing a title issue or skipping an inspection, it’s signing a lease structured for today’s headcount and today’s operations without accounting for where the business is going. A lease that fits perfectly on day one can become a serious operational and financial constraint by year three.
Stress-test the deal against these scenarios before signing:
- Growth scenario: If headcount increases by 30–50% in the next three years, does the lease give you expansion rights to adjacent space? If not, can you negotiate them?
- Contraction scenario: If market conditions change or remote work adoption accelerates, can you give back space or sublease without catastrophic cost?
- Exit scenario: If the business is acquired, merged or pivots, does the lease allow assignment to a successor entity without triggering landlord approval and fees?
- Renewal scenario: When the term expires, do you have the right to renew at predictable economics, or will you be renegotiating from zero in whatever market conditions exist at that time?
A lease that answers these questions favorably is often worth more than a lower face rent with no flexibility. Hughes Marino can help evaluate every transaction against its long-term strategic fit, not just whether the economics work today.
The Tenant’s Advantage: Independent Representation at Every Step
Commercial lease due diligence is most effective when you have an advisor whose only obligation is to you. Traditional commercial real estate brokerages represent both landlords and tenants, creating an inherent conflict that can compromise the advice you receive at exactly the moments it matters most: during inspection, during lease review and during negotiation.
Hughes Marino specializes in representing tenants, with in-house financial analysts, attorneys and market researchers whose sole objective is protecting and advancing your interests. From the first site visit to final lease execution, every recommendation is made with one question in mind: what’s best for you?
