The Federal Absence: Why State Law Governs Everything
Unlike residential leasing, which has been shaped by federal laws including the Fair Housing Act, the Servicemembers Civil Relief Act, and various federal eviction moratorium authorities, commercial leasing is almost entirely governed by state law. There is no federal commercial landlord-tenant act. There is no federal protection for commercial tenant security deposits. There is no federal right to cure a commercial lease default before eviction.
This means that the lease you sign in Texas operates under fundamentally different legal rules than an identical lease signed in California. The landlord's remedies differ. The tenant's rights differ. The eviction process differs. The holdover consequences differ. And unless your lease explicitly specifies which state's law governs (a "choice of law" provision), courts will apply the law of the state where the property is located.
The Uniform Commercial Code (UCC) governs some commercial lease transactions — specifically personal property leases under Article 2A — but commercial real estate leases are generally governed by common law and state-specific statutes, not the UCC.

The Framework: What State Law Can (and Cannot) Control
Before diving into state-specific rules, it's important to understand the framework: commercial leases are primarily contracts, and in most states, the contract's terms control over default statutory rules. This means a well-drafted commercial lease can often modify, expand, or limit the state law defaults. However, there are certain "non-waivable" statutory rights that even a signed contract cannot override.
| Issue Area | Governed By | Can Parties Modify by Contract? |
|---|---|---|
| Eviction procedure | State statute + common law | Partially — notice periods often statutory minimums |
| Security deposit interest | State statute (if any) | Rarely — if statute requires interest, it applies |
| Self-help lockout | State statute | In some states yes; in others no regardless of lease language |
| Holdover rent rate | Lease contract (primarily) | Yes — lease governs |
| Foreclosure survival | State recording law + mortgage priority | Partially — SNDA agreements modify practical outcome |
| Implied warranty of fitness | Common law (varies by state) | Yes — most states allow contractual waiver |
| Lease assignment/subletting | Lease contract (primarily) | Yes — lease governs |
| Landlord's duty to mitigate on breach | State statute/common law | Partially — some states impose this as non-waivable |
State-by-State Commercial Lease Law Overview
The following sections cover the most commercially significant states by lease market volume. For each state, we address: eviction process and notice requirements, self-help lockout rules, security deposit treatment, holdover tenancy rules, landlord's duty to mitigate, and notable tenant-favorable or landlord-favorable legal rules.
California offers the most robust commercial tenant protections among major states. Its courts have historically interpreted ambiguous lease language contra proferentem (against the drafter, typically the landlord) and impose a robust implied covenant of good faith and fair dealing that goes beyond most states. Key California commercial lease rules:
- Eviction process: Commercial landlords must provide written notice (typically 3 days to pay or quit) before commencing an unlawful detainer action. Court-supervised eviction is required; self-help lockout is prohibited.
- Security deposits: Commercial landlords are not required by statute to hold deposits in separate accounts, but must return deposits within 30 days after lease termination with an itemized written statement of deductions.
- Duty to mitigate: California imposes a statutory duty on commercial landlords to make reasonable efforts to re-let the space after a tenant default. A landlord who fails to mitigate cannot recover damages for rent that could have been avoided through reasonable re-letting efforts. This is more tenant-favorable than many states.
- Holdover: California commercial holdover law is primarily governed by the lease. If the lease is silent, a holdover creates a month-to-month tenancy terminable by 30-day notice. However, if the lease specifies holdover rent (e.g., 150% of base rent), that provision controls.
- Notable: California's CEQA (California Environmental Quality Act) can affect commercial tenant uses in ways not seen in other states. If your intended use changes the environmental baseline, the landlord may face CEQA obligations that complicate build-out permits.
New York commercial lease law is shaped largely by decades of New York City real estate litigation, making it one of the most extensively litigated commercial lease jurisdictions in the country. NYC's sophisticated commercial real estate market means both landlord and tenant positions are extensively documented in case law.
- Eviction process: New York requires a formal summary proceedings process (commercial holdover or non-payment proceeding) in the Civil Court. Self-help lockout is prohibited for commercial tenants in New York City. Notice requirements vary by borough and lease terms.
- Security deposits: New York does not require commercial security deposits to be held separately or earn interest. Landlords have broad discretion in applying commercial deposits.
- Duty to mitigate: New York does not impose a duty to mitigate on commercial landlords. A landlord may elect to let space sit vacant and sue the departing tenant for rent accruing monthly — for the entire remaining lease term in some circumstances. This is highly landlord-favorable and catches many tenants by surprise.
- Holdover: In New York, a commercial holdover tenant is at the landlord's election: the landlord may either treat the holdover as a new month-to-month tenancy (by accepting rent) or as a trespasser and proceed immediately with eviction. Some courts have found that a landlord accepting even one month's rent creates a new tenancy for that period.
- Notable: New York enforces personal guaranty "Good Guy" clauses commonly used in NYC commercial leases. A Good Guy clause allows a guarantor to be released from future rent obligations if the tenant vacates, surrenders the space, and gives proper notice by a specified date — providing a defined exit for personal guarantors that is uncommon in other states.
Texas is one of the most landlord-favorable commercial lease states in the country. The Texas Property Code explicitly authorizes commercial landlord self-help remedies in certain circumstances and imposes minimal statutory obligations on landlords. Texas commercial tenants should negotiate strongly for contractual protections they cannot rely on state law to provide.
- Eviction process: Texas requires a 3-day written notice to vacate (or longer as specified in the lease) before filing an eviction (forcible detainer) suit. Eviction proceedings in Texas move quickly — often resolved within 2–4 weeks of filing, compared to months in states like California or New York.
- Self-help lockout: Texas Property Code Section 93.002 explicitly allows commercial landlords to change locks if a tenant is delinquent in rent, without court process, as long as the tenant is provided a key upon payment of rent or given access to retrieve personal property. This is one of the few states that expressly permits commercial self-help lockout. The scope is limited but real.
- Security deposits: Texas imposes no statutory requirements for commercial security deposits — no cap, no separate account requirement, no interest obligation. The lease governs entirely.
- Duty to mitigate: Texas does not impose a clear duty to mitigate on commercial landlords. Texas courts have historically allowed landlords to elect between mitigation and continuing to hold the tenant responsible for rent. Some recent cases suggest a trend toward mitigation, but this is not settled law.
- Holdover: Texas commercial holdover is governed by the lease. If the lease specifies a holdover rent multiplier (common: 150–200% of base rent), courts enforce this strictly. Without a lease provision, Texas common law generally creates a month-to-month tenancy by implication.
Florida's commercial landlord-tenant law (Florida Statutes Chapter 83, Part I) is relatively thin, providing less statutory structure than residential law and leaving most commercial tenant rights to be negotiated contractually. Florida courts are generally efficient at processing commercial evictions.
- Eviction process: Florida requires written notice (3 days for non-payment of rent, unless the lease specifies otherwise) before filing an eviction action. Florida's county court system processes commercial evictions relatively quickly, often within 30–45 days of filing for uncontested cases.
- Self-help lockout: Florida Statutes Section 83.05 prohibits self-help remedies for commercial landlords — court process is required before a landlord can take possession. However, if the lease contains a contractual right of entry upon default, Florida courts have sometimes permitted lease-authorized non-judicial remedies.
- Security deposits: Florida commercial security deposits are not regulated by statute. No cap, no separate account requirement, no interest obligation. The lease governs.
- Duty to mitigate: Florida imposes a duty to mitigate on commercial landlords in most circumstances. A landlord who unreasonably fails to re-let after tenant default cannot recover rent that reasonable mitigation would have avoided.
- Notable: Florida's Assignment of Rents doctrine is well-established — a landlord's lender may be able to claim rents directly from tenants in the event of landlord default on the mortgage, without waiting for foreclosure. SNDA agreements protecting Florida commercial tenants from this risk are particularly important.
Illinois commercial lease law is primarily contract-based, with courts applying general contract interpretation principles to commercial lease disputes. Illinois courts have been active in developing commercial tenant protections through case law, particularly in the Chicago market.
- Eviction process: Illinois requires a 5-day written demand for rent (or 10-day notice for other lease violations) before filing an eviction (forcible entry and detainer) action. Cook County (Chicago) has specific court procedures that add complexity to commercial evictions.
- Self-help lockout: Illinois prohibits self-help commercial evictions. A landlord cannot change locks or remove personal property without court process. Landlords who engage in prohibited self-help may face statutory damages.
- Security deposits: Illinois does not impose statutory requirements on commercial security deposits. However, Illinois courts have shown willingness to treat commercial deposit retention as a damages issue — requiring landlords to document actual damages rather than retain deposits as windfalls when actual damages are lower.
- Duty to mitigate: Illinois imposes a duty to mitigate on commercial landlords. After a tenant default, the landlord must make reasonable efforts to re-let the space, and cannot recover rent that would have been covered by reasonable mitigation efforts.
- Notable: Illinois courts apply the doctrine of substantial performance in commercial lease contexts, sometimes allowing a tenant to avoid default consequences where the lease violation was minor and did not substantially deprive the landlord of the benefit of the lease.
Washington State has developed some of the more tenant-protective commercial lease law outside of California, with courts interpreting commercial leases strictly and imposing meaningful obligations on landlords. The Seattle commercial real estate market has generated extensive case law on commercial tenant protections.
- Eviction process: Washington requires at least a 3-day written unlawful detainer notice for non-payment of rent. Self-help lockout is prohibited. Washington courts can move slowly on contested commercial evictions, providing tenants with more time to cure or negotiate than in Texas or Florida.
- Security deposits: Washington does not impose comprehensive statutory regulations on commercial security deposits, but courts have been active in enforcing deposit return obligations where landlords cannot document actual damages equal to or exceeding the deposit amount.
- Duty to mitigate: Washington imposes a clear duty to mitigate on commercial landlords. The landlord must make commercially reasonable efforts to re-let after a tenant default, and courts will reduce damage awards by the amount that reasonable mitigation would have recovered.
- Notable: Washington has enacted Commercial Tenant Protection legislation (RCW 59.18.220 extended to some commercial situations) that has been expanded in recent years following significant advocacy from small commercial tenants during the COVID-19 pandemic. Seattle's local ordinances have also provided additional protections not available in other jurisdictions.
Key Legal Issues That Vary Most Dramatically by State
1. Landlord's Duty to Mitigate After Tenant Default
This is the most financially significant variation across states for commercial tenants. When a tenant abandons a space or defaults on rent, the question of whether the landlord must try to re-let the space dramatically affects the tenant's total damage exposure.
| State | Duty to Mitigate? | Practical Impact on Tenant |
|---|---|---|
| California | Yes | Tenant's liability limited to rent not covered by reasonable re-letting efforts |
| New York | No | Landlord may let space sit vacant and sue for full remaining rent |
| Texas | Unclear | Landlord can choose; mitigation trends in recent case law but not settled |
| Florida | Yes | Tenant's liability limited by mitigation obligation |
| Illinois | Yes | Landlord must make reasonable re-letting efforts |
| Washington | Yes | Clear duty to mitigate; strong tenant-favorable case law |
| Georgia | No | Traditional "no duty" state; landlord can sue for full remaining rent |
| Colorado | Yes | Mitigation required; re-letting at a lower rent reduces but doesn't eliminate liability |
2. Self-Help Lockout: Can a Landlord Change Your Locks Without Court Process?
The self-help lockout question is the most dramatic legal difference between states. In states that prohibit self-help, a landlord who changes your locks is committing an illegal act that exposes them to significant damages. In states that permit it (like Texas), a delinquent tenant can come to work one morning to find their locks changed with no prior court involvement.
Annual rent: 5,000 × $50 = $250,000/year
Remaining term: 7 years
Total remaining rent obligation: $250,000 × 7 = $1,750,000
In a state WITH duty to mitigate (California):
Landlord re-lets space after 6 months at $45/SF
Tenant's exposure: 6 months vacancy ($125,000) + re-letting costs ($25,000) = $150,000
In a state WITHOUT duty to mitigate (New York):
Landlord elects not to re-let; sues for remaining rent
Tenant's exposure: Up to $1,750,000 + landlord's legal fees
3. Holdover Tenancy: Month-to-Month vs. Year-to-Year Conversion
When a commercial tenant stays past their lease expiration without signing a new lease or renewal, the resulting "holdover tenancy" is treated differently by different states — and the financial consequences can be severe.
In most states, the lease's holdover provision controls. But if the lease is silent, common law defaults apply. In some states, a holdover commercial tenant is automatically converted to a month-to-month tenancy (relatively favorable). In others, courts have found that a holdover creates a new one-year tenancy — binding the tenant to an entire additional year of rent at the landlord's option. This year-to-year holdover rule historically applied in several northeastern states and can still be argued by landlords in states with limited statutory guidance.
The lesson: never let your commercial lease expire without either signing a renewal, negotiating a month-to-month extension in writing, or giving proper notice of departure. The holdover penalty — whether it's 150% rent for one month or a forced new one-year term — is almost always worse than the alternative.
4. SNDA Agreements and Foreclosure Protection
When a property goes into foreclosure, what happens to your lease depends on:
- Whether your lease is senior or junior to the mortgage
- Whether you have an executed SNDA agreement with the lender
- The state's foreclosure law and timeline
State foreclosure timelines vary dramatically: judicial foreclosure states like New York (12–24 months) and Florida (6–18 months) give tenants more time to make arrangements; non-judicial foreclosure states like California and Texas (3–6 months) can move very quickly. In any state, having an executed SNDA with the lender is the most reliable protection for a commercial tenant facing a landlord mortgage default.
The 12-Item State Law Compliance Checklist
- Choice of Law Clause Verified: Confirm your lease specifies governing state law (should be the state where the property is located); if multi-state company, understand you may face different rules in different locations.
- Eviction Notice Requirements Researched: Confirm the minimum notice period required by your state before eviction proceedings can begin; ensure your lease doesn't waive minimum statutory notice if state law prohibits such waiver.
- Self-Help Lockout Rule Known: If operating in Texas or another state where commercial self-help is permitted, negotiate contractual protections against lockout without notice; ensure you're never more than one month behind on rent in self-help states.
- Duty to Mitigate Status Verified: If operating in a no-mitigation state (New York, Georgia), your lease should include a landlord covenant to take commercially reasonable steps to re-let after any tenant default; this converts a state-law gap into a contractual obligation.
- Holdover Provision Reviewed: Lease must specify holdover rent rate and the type of tenancy created (month-to-month preferred over year-to-year); if lease is silent, research your state's common law default before expiration.
- Security Deposit Terms Negotiated: Because most states don't regulate commercial deposits, negotiate deposit terms in the lease: return timeline (30 days preferred), itemized statement requirement, and conditions for deduction that match actual documented damage only.
- SNDA Agreement Obtained: If the property has existing financing, obtain an executed SNDA agreement from the lender protecting your right to remain in occupancy through a foreclosure as long as you're not in default.
- Force Majeure Clause Reviewed for State-Specific Enforcement: Force majeure clauses are interpreted differently by state. In no-mitigation, strict-impossibility states (NY, TX), ensure your clause explicitly names pandemic, government shutdown orders, and other specific events you want protection from.
- Local Ordinances Checked: Many cities impose additional commercial tenant protections beyond state law. Seattle, San Francisco, and New York City all have local commercial tenant protections worth researching before signing.
- Recording Requirements Met: In most states, recording a memorandum of lease provides public notice of your leasehold and protects your lease priority against subsequent encumbrances. Confirm whether recording is advisable for your lease term and property situation.
- Assignment/Subletting State Law Checked: Some states impose implied landlord reasonableness obligations on lease assignment consent even without explicit lease language; know whether your state fills this gap or whether your lease must explicitly provide it.
- Implied Warranty of Fitness Applicability Confirmed: Some states recognize an implied warranty that commercial space is reasonably fit for the tenant's intended use. If your state recognizes this warranty, it provides a backstop right to cure or terminate if the space proves unsuitable — valuable protection in any industry-specific use case.

Analyze My Lease →Multi-State Tenants: Managing Jurisdictional Complexity
Businesses that lease commercial space in multiple states face an additional layer of complexity: different lease agreements in each state may have identical language but produce dramatically different legal outcomes. A personal guaranty with a "Good Guy" clause that works perfectly in New York may be interpreted very differently by a Texas court.
Best practices for multi-state commercial tenants:
- Use state-specific lease addenda: Rather than trying to write one national lease that works everywhere, use a standard base lease with state-specific addenda that address the unique requirements of each jurisdiction.
- Maintain jurisdiction-specific legal relationships: Identify a commercial real estate attorney in each major market you operate in. Use them to review new leases in their market before signing.
- Standardize document management: Use a lease abstraction and management system to maintain standardized data across all your leases in all states, enabling quick comparison and identification of out-of-norm provisions. LeaseAI's Tenant Resources page has tools specifically designed for multi-location tenants.
- Track renewal and notice deadlines centrally: Missing a renewal option notice deadline has no legal remedy in most states. A missed deadline is a missed right. Centralized tracking across all jurisdictions is essential for multi-site tenants.

Conclusion: State Law Is Not a Background Issue
Commercial lease law is not a background technicality that only matters when things go wrong. The state-specific legal framework governing your lease shapes your daily rights as a tenant — your ability to sublet, your exposure if you need to exit early, your protection against a landlord's financial problems, and your remedies if the landlord fails to maintain the building. Understanding your state's commercial lease law environment is a prerequisite to negotiating a lease that adequately protects you.
