Commercial Lease Dispute Litigation
Commercial lease disputes are among the most common and financially significant business conflicts in California. Whether you are a landlord seeking to enforce lease terms or a tenant fighting unjust charges, the outcome of a commercial lease dispute can have a profound impact on your business operations and bottom line. These disputes arise over a wide range of issues including rent increases, common area maintenance (CAM) charges, tenant build-out obligations, lease termination, assignment and subletting restrictions, and landlord maintenance failures.
If you are involved in a commercial lease dispute in San Jose, San Francisco, Oakland, Redwood City, or anywhere in Santa Clara County, the attorneys at RV Litigation Group PC can help. We represent both commercial landlords and tenants in lease disputes, and we bring the transactional knowledge and litigation experience needed to resolve these matters efficiently and favorably.
Unlike residential leases, which are heavily regulated by statute, commercial leases in California are largely governed by the terms of the lease agreement itself. This means the specific language of the lease is critically important — ambiguous terms, missing provisions, and poorly drafted clauses are frequent sources of disputes. At RV Litigation Group PC, we analyze every provision of the lease to identify our clients' strongest arguments.
Commercial lease disputes frequently involve substantial amounts of money and significant business disruption. A landlord's failure to maintain the premises can shut down a tenant's operations. A tenant's failure to pay rent can threaten a landlord's mortgage obligations. We approach every case with an understanding of the business realities at stake and a strategy designed to achieve the best practical outcome.
What the Law Says
Civil Code 1951.2 — Landlord Remedies for Breach
""If a lessee of real property breaches the lease and abandons the property before the end of the term... the lessor may recover from the lessee: (1) The worth at the time of award of the unpaid rent which had been earned at the time of termination; (2) The worth at the time of award of the amount by which the unpaid rent which would have been earned after termination until the time of award exceeds the amount of such rental loss that the lessee proves could have been reasonably avoided..."" — California Civil Code Section 1951.2
When a commercial tenant breaches the lease and abandons the premises, the landlord's remedies are governed by Civil Code 1951.2. The landlord can recover past-due rent, future rent (discounted to present value and reduced by amounts that could have been mitigated through re-letting), and any other damages proximately caused by the breach. However, the landlord has a duty to mitigate damages by making reasonable efforts to re-let the property.
Civil Code 1951.4 — Landlord's Right to Continue Lease
""(b) The landlord may continue the lease in effect after the lessee's breach and abandonment and recover rent as it becomes due, if the lessee has the right to sublet or assign, subject only to reasonable limitations."" — California Civil Code Section 1951.4
If the lease allows the tenant to sublet or assign (subject to reasonable limitations), the landlord has the option to keep the lease in effect even after the tenant abandons the premises. This allows the landlord to recover rent as it becomes due without having to re-let the property. This provision is particularly important in commercial leases with above-market rents, where the landlord would receive less income from a new tenant than from enforcing the existing lease.
Real-World Examples
These scenarios illustrate how commercial lease disputes commonly arise in the Bay Area:
A retail tenant in a San Jose shopping center discovers that the landlord has been including capital improvement costs in the annual CAM (common area maintenance) reconciliation, even though the lease excludes capital expenditures from CAM charges. The tenant has been overpaying by $15,000 per year for three years. The tenant brings a breach of contract claim seeking reimbursement of the overcharges, and the court orders the landlord to refund $45,000 plus interest and adjust future CAM billings to comply with the lease terms.
A San Francisco restaurant tenant invests $350,000 in build-out improvements based on the landlord's written agreement to provide a tenant improvement allowance of $200,000. After the improvements are completed, the landlord refuses to pay the allowance, claiming the improvements do not meet the specifications outlined in the lease. The tenant brings a breach of contract and promissory estoppel claim to recover the agreed-upon allowance.
An Oakland office tenant exercises an early termination option in its lease, providing the required 12 months' notice and paying the specified termination fee. The landlord claims the notice was defective because it was sent by email rather than by certified mail as required by the lease. The landlord refuses to release the tenant, who continues to accrue rent at $25,000 per month. The tenant files a declaratory judgment action to confirm the validity of the termination notice and obtain release from the lease.
A Silicon Valley tech company seeks to assign its commercial lease to a buyer as part of a business sale. The lease requires landlord consent to assignment, "which shall not be unreasonably withheld." The landlord refuses consent without providing a reasonable basis. Under California law, a landlord's unreasonable refusal to consent to an assignment constitutes a breach of the lease, and the tenant can seek damages or specific performance compelling the landlord to consent.
What's at Stake
Commercial lease disputes involve significant financial exposure for both landlords and tenants. The specific terms of the lease control most outcomes.
| Dispute Type | Key Issues | Potential Recovery | Timeline |
|---|---|---|---|
| Rent Disputes | Nonpayment, rent escalation, percentage rent | Past-due rent, future rent, interest | 4-year SOL (written contract) |
| CAM Charges | Overcharges, excluded costs, reconciliation | Refund of overcharges, prospective adjustment | 4-year SOL (written contract) |
| Build-Out Disputes | TI allowance, specifications, completion | TI allowance, damages, specific performance | 4-year SOL (written contract) |
| Lease Termination | Early termination, notice defects, abandonment | Release from lease, damages, future rent | Varies by lease terms |
| Assignment/Subletting | Unreasonable withholding of consent | Specific performance, damages | 4-year SOL (written contract) |
Duty to mitigate: A critical issue in commercial lease disputes is the landlord's duty to mitigate damages. When a tenant abandons the premises, the landlord cannot simply let the space sit vacant and sue for the full remaining rent. Under Civil Code 1951.2, the landlord must make reasonable efforts to re-let the property, and the tenant's liability is reduced by the amount of rental loss that could have been reasonably avoided. However, under Civil Code 1951.4, if the lease allows subletting or assignment, the landlord may be able to keep the lease in effect and recover rent as it becomes due without mitigation.
How We Help
At RV Litigation Group PC, we handle commercial lease disputes from lease review through trial and enforcement. Our approach combines real estate expertise with aggressive litigation strategy.
1. Lease Review & Interpretation
We conduct thorough analysis of the lease agreement, identifying key provisions, ambiguities, and the parties' rights and obligations. Our review covers rent escalation clauses, CAM provisions, maintenance obligations, use restrictions, assignment and subletting provisions, default and cure provisions, and termination options. This analysis forms the foundation of our litigation strategy.
2. Pre-Litigation Negotiation
Many commercial lease disputes can be resolved through direct negotiation between the parties. We draft demand letters, conduct settlement negotiations, and mediate disputes to achieve efficient resolutions. Our goal is to resolve the dispute in a way that preserves the business relationship when possible while protecting our client's financial interests.
3. Unlawful Detainer & Eviction
When a commercial tenant defaults on rent or violates lease terms, we prosecute unlawful detainer actions to recover possession of the property. We also defend tenants against wrongful eviction actions. Our attorneys understand the strict procedural requirements of unlawful detainer proceedings and ensure every notice, filing, and hearing is handled correctly.
4. CAM Audit & Recovery
We audit CAM charges on behalf of tenants, reviewing landlord records, vendor contracts, and reconciliation statements to identify overcharges and excluded costs that were improperly passed through. We pursue claims for reimbursement of overcharges and negotiate prospective adjustments to ensure future compliance with lease terms.
5. Specific Performance
When monetary damages are inadequate, we seek specific performance — a court order requiring the other party to fulfill their lease obligations. This remedy is particularly valuable in disputes over assignment consent, tenant improvement allowances, and lease renewal options, where the tenant needs the landlord to act rather than simply pay money.
6. Trial & Judgment Enforcement
We try commercial lease disputes in Santa Clara County Superior Court, San Francisco Superior Court, and throughout Northern California. After obtaining a judgment, we pursue all available collection remedies including wage garnishment, bank levies, and property liens to ensure our clients recover the amounts awarded.
Frequently Asked Questions
The statute of limitations for breach of a written commercial lease is four years under CCP 337. For oral lease agreements, the limitations period is two years under CCP 339. These deadlines apply to claims for unpaid rent, breach of lease covenants, and other lease-related disputes.
Generally yes. Under Civil Code 1951.2, when a tenant abandons the premises, the landlord must make reasonable efforts to re-let the property. However, under Civil Code 1951.4, if the lease allows the tenant to sublet or assign, the landlord may keep the lease in effect and recover rent as it becomes due without mitigation.
No. If the lease requires landlord consent to assignment, California law implies that consent shall not be unreasonably withheld unless the lease expressly provides otherwise. An unreasonable refusal to consent can constitute a breach of the lease and expose the landlord to damages.
If a commercial tenant abandons the premises, the landlord can either terminate the lease and sue for damages under Civil Code 1951.2 (including past-due rent, future rent minus mitigation, and other damages), or keep the lease in effect and recover rent as it becomes due under Civil Code 1951.4 (if the lease allows subletting).
Generally no. California's rent control laws (including AB 1482, the Tenant Protection Act) apply to residential tenancies, not commercial leases. Commercial lease terms, including rent, are governed by the lease agreement itself and by market forces. However, some local ordinances may provide limited protections for certain small commercial tenants.
