Why Landlords Want Confidentiality Clauses
To understand confidentiality provisions in commercial leases, you need to understand why landlords insist on them. The answer is market information asymmetry — and the competitive advantage it gives them.
In a typical multi-tenant office building, shopping center, or industrial park, different tenants pay different rents. A tenant who signed a five-year lease in 2019 at $28/SF might be paying 25% below market in 2026. The anchor tenant might have negotiated $400/SF in TI allowance while a new small tenant received only $60/SF. The flagship retailer might have six months of free rent baked into their deal while the boutique next door got none.
If tenants freely compared notes, the landlord's ability to extract maximum value from each negotiation would collapse. Confidentiality clauses are the landlord's tool for maintaining that information advantage.
A secondary reason: lenders and investors who review the building's rent roll have expectations about minimum rents. If below-market deals become public knowledge, it can affect the building's appraised value and the landlord's ability to refinance.
Key Insight: Confidentiality clauses serve the landlord's interest, not yours. Every restriction in a confidentiality clause limits your market intelligence, negotiating leverage, and business flexibility. Negotiate every carve-out aggressively.
The Five Types of Commercial Lease Confidentiality Provisions
Not all confidentiality clauses are alike. Understanding the specific type you're dealing with determines your negotiating approach.
Type 1: Economic Terms Confidentiality
The most common form prohibits disclosure of any economic terms of the lease: base rent, rent escalation schedule, free rent periods, tenant improvement allowance amount, security deposit amount, and any rent credits or abatements. This is the core of virtually every commercial lease confidentiality clause.
Typical language: "Tenant shall not disclose to any third party the economic terms of this Lease, including without limitation the Base Rent, rent adjustments, Tenant Improvement Allowance, free rent periods, or any other financial concessions granted hereunder."
Type 2: Lease Existence Confidentiality
More aggressive clauses attempt to prohibit disclosure of the lease's existence — not just its terms. These are most common in high-profile retail situations (think a new concept testing a market before announcement) or when a major tenant doesn't want competitors to know they're expanding into a specific submarket.
These clauses are difficult to enforce once the tenant is operating visibly from the space, and courts tend to interpret them narrowly. But they can have teeth during the pre-opening period.
Type 3: Negotiation Confidentiality (NDA-in-Lease)
Some leases incorporate or reference a separate letter of intent (LOI) confidentiality provision, extending NDA obligations from the negotiation phase into the executed lease. This creates a chain of confidentiality obligations that can be difficult to track and may conflict with obligations to disclose material contracts in business sale contexts.
Type 4: Landlord Financial Information Confidentiality
When landlords provide financial disclosures during due diligence — building financials, operating cost histories, occupancy data — they often require tenants to keep that information confidential. This is a reciprocal protection that you should actually welcome, since it typically comes paired with your own confidentiality rights.
Type 5: Operational Confidentiality (Overreach)
The most dangerous type: clauses that extend confidentiality to the tenant's own business operations, proprietary processes, or client information conducted on the premises. These are common in life sciences, technology, and financial services leases, where landlords attempt to claim confidentiality protection over information related to the "use of the premises."
These clauses can directly conflict with tenants' regulatory obligations (public company disclosure requirements, for example), client NDA obligations, and whistleblower protection laws. Reject operational confidentiality language entirely.
| Confidentiality Type | What It Covers | Enforceability | Tenant Risk Level |
|---|---|---|---|
| Economic Terms | Rent, TI, free rent, escalations | High | Medium — manageable with carve-outs |
| Lease Existence | The fact that a lease was signed | Medium (pre-occupancy only) | Low after opening |
| Negotiation NDA | LOI and term sheet contents | High during negotiations | Low (usually expires) |
| Landlord Financials | Building performance data | High | Low (reciprocal) |
| Operational | Tenant business activities | Low — often unenforceable | Very High — reject this |
The Business Consequences of Over-Broad Confidentiality Clauses
Blocking Business Sale or Merger
When you sell your business, a buyer will demand full disclosure of all material contracts as part of due diligence. A confidentiality clause without a sale carve-out puts you in an impossible position: either breach the lease or deny the buyer information they need to close the transaction.
In the worst case, this can kill a deal or expose you to liability. The fix is simple: negotiate a carve-out for disclosure in connection with the sale, merger, or acquisition of the tenant's business, subject to the recipient signing a confidentiality agreement.
Blocking Financing and Refinancing
If you're financing equipment, obtaining a business loan, or seeking venture capital, lenders and investors will review your lease as a material asset. SBA lenders explicitly require review of all leases for businesses seeking 7(a) or 504 financing. A confidentiality clause without a lender carve-out can prevent you from providing required documentation.
Negotiate a carve-out for disclosure to "institutional lenders, investors, and financing sources in connection with bona fide financing transactions, subject to customary confidentiality obligations."
Blocking Sublease or Assignment Negotiations
If you need to sublease your space or assign the lease, prospective subtenants and assignees will want to review the lease terms. Without a sublease/assignment carve-out, you can't properly market the space. This is particularly damaging in early termination or contraction scenarios.
Securities Law Conflicts
Public company tenants and REITs have mandatory disclosure obligations under SEC rules. A lease that constitutes a "material contract" must be filed as an exhibit to SEC reports — including its economic terms. A landlord-imposed confidentiality clause does not override federal securities law, but the conflict can create friction and negotiating tension.
Public companies should include an express carve-out for disclosures required by applicable law, stock exchange regulations, or governmental order.
Practical Alert: An overly restrictive confidentiality clause can prevent you from completing a business sale, securing a bank loan, or even complying with your own client NDAs. Address this before signing — not after.
The Real Math: What Confidentiality Costs Tenants
The indirect financial cost of a confidentiality clause is hard to quantify but very real. When tenants can't benchmark their deals, landlords maintain information advantages worth real money.
Reason: Tenant couldn't access comp data; landlord's confidentiality clause suppressed market information
Annual rent overpayment: (42 - 38) × 3,000 SF = $12,000/year
5-year overpayment: $60,000
With TI differential (landlord gave others $80/SF vs $50/SF for this tenant): $90,000
Total cost of information asymmetry: ~$150,000
While a single lease confidentiality clause doesn't directly cause this overpayment, it's part of an ecosystem that keeps tenants in the dark. Tenants who hire tenant rep brokers — who have access to comp databases — partially offset this disadvantage.
Negotiating Confidentiality Provisions: The 8 Essential Carve-Outs
You cannot eliminate confidentiality clauses from most commercial leases — landlords won't agree. But you can negotiate carve-outs that protect your business in every scenario that matters. Here are the eight carve-outs to demand:
Carve-Out 1: Advisors and Professionals
You must be able to share lease terms with your own attorneys, accountants, financial advisors, brokers, and consultants who are working on your behalf. Standard language: "…excluding disclosure to Tenant's attorneys, accountants, financial advisors, and brokers who are subject to professional confidentiality obligations or have executed a confidentiality agreement."
Carve-Out 2: Business Sale or Merger
Critical for any tenant who might sell or merge their business. Language: "…or in connection with a bona fide sale, merger, acquisition, or transfer of all or substantially all of Tenant's business or assets, provided the recipient executes a written confidentiality agreement no less protective than this provision."
Carve-Out 3: Financing Transactions
Language: "…or to institutional lenders, investors, private equity sponsors, or other financing sources in connection with bona fide debt or equity financing of Tenant's business."
Carve-Out 4: Legal Process and Government Orders
You cannot be required to violate a court order or regulatory requirement. Language: "…or as required by applicable law, court order, governmental regulation, or the rules of any national securities exchange, provided Tenant gives Landlord prompt prior written notice of such required disclosure to the extent permitted by law."
Carve-Out 5: Sublease and Assignment Marketing
Language: "…or to bona fide prospective subtenants, assignees, or their advisors in connection with a proposed sublease or assignment permitted under this Lease."
Carve-Out 6: Employees and Management
You need to be able to discuss the lease with your own senior management, board of directors, and employees who have a need to know. Language: "…or to Tenant's officers, directors, partners, members, and employees who have a reasonable need to know such information in connection with Tenant's business."
Carve-Out 7: Insurance Procurement
Your insurance broker may need lease details to place appropriate coverage. Language: "…or to Tenant's insurance brokers and carriers in connection with the procurement or maintenance of insurance required under this Lease."
Carve-Out 8: Lease Dispute Resolution
If a dispute arises, you need to be able to discuss the lease in arbitration or litigation. Language: "…or in connection with any dispute resolution proceeding, arbitration, or litigation relating to this Lease."
| Carve-Out | Why Critical | Landlord Resistance Level |
|---|---|---|
| Advisors/Professionals | Can't operate without attorneys, accountants | Low — usually accepted |
| Business Sale/Merger | Blocks exit transactions without it | Medium — negotiate carefully |
| Financing | SBA/bank lenders require lease review | Low — lenders need it |
| Legal Process | Cannot override court orders | Very Low — standard |
| Sublease/Assignment | Can't market space without terms | Medium — landlord may push back |
| Employees/Management | Need internal review | Low — reasonable request |
| Insurance | Brokers need coverage details | Very Low — standard |
| Dispute Resolution | Can't pursue claims without evidence | Low — courts require it anyway |
Side Letters: The Hidden Confidentiality Risk
Many landlords use side letters — separate agreements that modify or supplement the main lease — precisely to keep sensitive concessions out of the publicly recorded lease document. If your building is in a jurisdiction that records commercial leases (or a memorandum thereof), the landlord may push free rent periods, personal guarantee burndown schedules, and TI overage payments into a side letter specifically to avoid recording.
Side letters typically carry their own confidentiality requirements, often more restrictive than the main lease. Key protections to negotiate:
- Confirm the side letter is binding on successor landlords (critical if the building is sold)
- Ensure the side letter is referenced in the main lease so future lenders are aware of it
- Negotiate the same carve-outs in the side letter as in the main lease
- Get all side letter obligations expressly survive building sale and assignment of landlord's interest
Warning: If a landlord says "we'll put that in a side letter," ask whether the main lease references the side letter. An unrecorded, unreferenced side letter may not bind a successor landlord who buys the building.
Mutual Confidentiality: Protecting Your Negotiating Position
Savvy tenants don't just accept landlord confidentiality obligations — they negotiate reciprocal ones. If you've disclosed sensitive financial information to the landlord during the underwriting process (business plans, revenue projections, personal financial statements), you have legitimate interests to protect too.
A mutual confidentiality clause protects both parties equally. Push for language like: "Each party agrees to keep the terms of this Lease confidential, except as permitted by the carve-outs set forth in this Section." This framing makes the landlord as bound as you are, and it's a reasonable compromise most landlords will accept.
Confidentiality in Multi-Tenant Buildings: Benchmarking Workarounds
Even with confidentiality clauses in place, savvy tenants find legitimate ways to benchmark their deals:
- Tenant rep brokers: Brokers have access to comps databases (CoStar, CBRE analytics) that aggregate market rent data without violating individual lease confidentiality
- Public filings: SEC-reporting public companies often disclose material lease terms; these are publicly available without any confidentiality restriction
- Appraisal reports: Commercial appraisals often cite market rent ranges; request your landlord's most recent appraisal under estoppel or due diligence
- Broker market surveys: Major brokerages publish quarterly market surveys with average asking rents and concession levels by submarket
- RFP process: Issue a formal Request for Proposals to multiple buildings simultaneously — this generates real competing offers that reveal actual market terms
Special Situations: Healthcare, Law Firms, and Financial Services Tenants
Certain tenant industries face unique confidentiality considerations that go beyond standard lease provisions.
Healthcare Tenants: HIPAA Complications
Healthcare tenants — medical offices, dental practices, behavioral health centers — operate under HIPAA's patient confidentiality requirements. A landlord-imposed confidentiality clause that covers "activities conducted on the premises" could theoretically conflict with HIPAA compliance obligations, which require sharing patient information with insurers, government agencies, and in emergencies.
Healthcare tenants should explicitly carve out all disclosures required or permitted by HIPAA, applicable state health codes, and federal healthcare regulations. This carve-out is non-negotiable for any licensed healthcare provider.
Law Firms: Attorney-Client Privilege
A commercial lease cannot override attorney-client privilege, but an overly broad operational confidentiality clause could create friction. Law firms should include a carve-out for all disclosures that are required or permitted by applicable rules of professional conduct and bar association ethics rules.
Financial Services: SEC and FINRA Obligations
Investment advisors, broker-dealers, and other SEC/FINRA-regulated entities have recordkeeping and disclosure obligations that cannot be waived by contract with a private party. All regulated financial tenants should include a sweeping carve-out for disclosures required by any federal or state financial regulatory authority, including the SEC, FINRA, CFTC, OCC, and state banking commissions.
What Happens If You Breach a Confidentiality Clause?
Most confidentiality breaches in commercial leases are discovered through hearsay — a tenant mentions their rent to another tenant who mentions it to their broker who mentions it to the landlord. The practical reality is that proving damages from a confidentiality breach is extremely difficult for landlords.
To win actual damages, a landlord would need to prove that your disclosure caused them to receive less rent from another tenant or lose a prospective tenant who used the information. This causal chain is hard to establish. Courts typically award nominal damages or injunctive relief, not large monetary awards.
That said, a confidentiality breach can:
- Damage your relationship with the landlord, affecting renewal negotiations
- Trigger a "default" notice under leases where breach of any covenant constitutes an event of default
- Lead to costly litigation even if the landlord ultimately loses
The prudent approach is to comply with confidentiality clauses while ensuring you've negotiated the carve-outs you need. Don't share rent terms casually; when disclosure is needed, make sure it falls within an explicit carve-out.
Best Practice: When disclosing lease terms under a permitted carve-out, document the disclosure. Send a brief email: "Per the confidentiality carve-out in Section X of our lease, I'm sharing the following lease terms with [name] in connection with [permitted purpose]." This documentation protects you if the landlord later claims a breach.
Confidentiality Provisions and Lease Abstracts
If you use AI-powered lease abstraction tools like LeaseAI to review and abstract your lease, the resulting lease abstract contains the economic terms of your lease. Under a typical confidentiality clause, sharing this abstract with third parties may constitute a breach unless the recipient falls within a permitted carve-out category.
Practical guidance: treat your lease abstract as confidential by default. Share it only with advisors (lawyers, accountants, brokers) who fall within the professional carve-out, and document those disclosures.
Negotiating Confidentiality Provisions: Sample Redline Language
Here's a practical example showing how to redline a standard landlord confidentiality clause:
12-Item Confidentiality Provision Checklist for Tenants
- Identify every confidentiality clause in the lease, side letters, and amendments — some provisions are buried in definition sections
- Determine whether the clause covers only economic terms or extends to lease existence or tenant operations
- Negotiate the clause to be mutual — binding landlord as well as tenant
- Confirm carve-out for professional advisors (attorneys, accountants, brokers, consultants)
- Confirm carve-out for business sale, merger, or acquisition with NDA requirement on buyer
- Confirm carve-out for debt and equity financing transactions
- Confirm carve-out for legal process, court orders, and regulatory requirements
- Confirm carve-out for sublease and assignment marketing (with NDA on prospects)
- Reject any operational confidentiality clause — limit to lease economic terms only
- If a side letter is used, negotiate identical carve-outs and confirm it binds successor landlords
- Include a carve-out for your industry-specific regulatory obligations (HIPAA, SEC, FINRA as applicable)
- Document all disclosures made under permitted carve-outs to protect against future breach claims
