A commercial lease creates a legal relationship between a property owner and a business tenant that is fundamentally different from a residential rental. California’s residential landlord-tenant protections, including the Tenant Protection Act’s rent caps, the implied warranty of habitability, and the mandatory entry-notice rules, do not automatically apply to commercial properties. Instead, the rights and obligations of the parties are shaped primarily by the lease itself, applicable California statutes, and local land-use regulations.
That distinction matters in practical terms. A commercial lease for an office building, retail space, restaurant, warehouse, or industrial facility is a negotiated contract. The parties have greater freedom to define their relationship. But that freedom also means mistakes or gaps in the lease can create serious problems when a dispute arises.
Kassouni Law’s California real estate practice represents property owners, developers, and business tenants in commercial real estate matters, including lease disputes, property-rights claims, and commercial litigation.
What Is Commercial Real Estate Law in California?
Commercial real estate law governs the ownership, leasing, development, and use of property that is not used primarily as a private residence. It covers a wide range of property types:
- Office buildings and business parks.
- Retail properties, strip malls, and shopping centers.
- Industrial and manufacturing facilities.
- Warehouses and distribution centers.
- Restaurants and hospitality properties.
- Mixed-use developments combining commercial and residential uses.
- Commercial development and construction projects.
The legal framework draws on California contract law, real property law, and specific California statutes that apply to commercial transactions. Unlike residential landlord-tenant law, commercial real estate law does not impose a fixed set of tenant protections regardless of the lease. The lease document is the primary source of the parties’ rights and obligations, and its terms matter enormously.
What Rights Do Commercial Property Owners Have in California?
A commercial property owner’s rights depend heavily on the lease terms and applicable law. Common owner rights include:
- Collecting rent: The owner is entitled to rent on the dates and in the amounts specified in the lease. When a tenant fails to pay, Code of Civil Procedure section 1161 allows the owner to serve a three-day notice to pay or quit, the first step in an unlawful detainer proceeding.
- Enforcing lease terms: The owner can require the tenant to operate within the permitted use, comply with building rules, maintain required insurance, and observe other material lease obligations.
- Recovering costs: Where the lease provides for it, the owner may recover operating expenses, taxes, insurance, common area maintenance charges, and other costs from the tenant.
- Accessing the property: Commercial leases typically give the owner the right to enter for inspections, repairs, and showings, subject to the notice and conditions in the lease.
- Addressing defaults: When a tenant breaches the lease, the owner can serve notice, demand cure, and pursue termination and eviction through lawful process if the breach continues.
- Pursuing damages: Under Civil Code section 1951.2, when a tenant abandons or a lease is terminated for breach, the owner may recover damages, but must make reasonable efforts to relet the property and mitigate losses.
One important California rule: under Civil Code section 1951.4, a commercial property owner may elect not to terminate the lease after a tenant breach. Instead, the owner keeps the lease in place and continues to seek rent as it comes due, provided the lease permits assignment and the owner does not prevent the tenant from subleasing or assigning.
What Rights Do Commercial Tenants Have in California?
Commercial tenants have fewer statutory protections than residential tenants. The lease is the principal source of a tenant’s rights. Within the lease, tenants typically have the right to:
- Occupy and use the premises for the purposes specified in the lease for the full lease term, as long as they are not in default.
- Receive the benefit of any agreed improvements, build-out obligations, or tenant-improvement allowances the landlord promised.
- Enforce lease provisions that favor the tenant, including renewal options, exclusivity clauses, relocation restrictions, and rent terms.
- Challenge rent increases, CAM charges, or other cost recoveries that exceed what the lease permits.
- Seek remedies when a landlord materially breaches the lease, such as by failing to provide agreed services or make required repairs.
California does not impose a general implied warranty of habitability on commercial properties the way it does for residential ones. Whether a commercial landlord is obligated to make repairs depends on the lease terms and applicable law, not a statutory default rule.
Commercial tenants also have no protection from statewide rent caps. California’s Tenant Protection Act does not apply to commercial leases. The rent a tenant pays is whatever the lease says, and increases are governed by the lease terms rather than any state rent-control ceiling.
California Commercial Lease Agreements
The commercial lease is the legal foundation of every landlord-tenant relationship for non-residential property. Unlike residential leases, commercial leases are negotiated documents, often heavily customized, and can be dozens or even hundreds of pages long for complex properties.
Key Lease Terms
A well-drafted commercial lease addresses, among other things:
- Rent: The base rent amount, payment schedule, and any escalation formula. Many commercial leases include annual rent increases tied to the Consumer Price Index or a fixed percentage.
- Lease term and renewal options: The initial term length and any options to extend, including the rent for any renewal period and the notice required to exercise the option.
- Permitted use: What the tenant is allowed to do on the premises. A use restriction that is too narrow can prevent the tenant from adapting the business over time. A restriction that is too broad may allow uses the owner finds objectionable.
- Security deposit: The amount and conditions for using and returning the deposit. Unlike residential leases, commercial deposits are not subject to California’s one-month cap or the 21-day return rule.
- Maintenance and repairs: Which party is responsible for which systems and surfaces. Lease provisions on maintenance and repairs can vary significantly.
- Insurance: What types and levels of coverage each party must carry and how the parties are named on each other’s policies.
- Taxes and operating expenses: Whether the tenant pays only base rent or also contributes to property taxes, insurance, and other operating costs.
- Common area maintenance (CAM): The tenant’s share of costs for shared spaces, parking, landscaping, and building systems.
- Assignment and subleasing: Whether the tenant can transfer the lease, and under what conditions.
- Default provisions and notice: What constitutes a default, what notice the defaulting party receives, and how much time they have to cure it.
- Personal guarantees: Whether an individual or related entity guarantees the tenant’s lease obligations. Common in leases to smaller businesses or new tenants without a credit history.
- Early termination: Whether either party has the right to terminate before the lease expires, and what payments or conditions apply.
Lease Types
Commercial leases are commonly categorized by how expenses are allocated:
Gross lease: The tenant pays a fixed rent and the owner covers most or all operating expenses, including taxes, insurance, and maintenance.
Net lease: The tenant pays base rent plus some or all of the property’s operating expenses. A triple-net lease (NNN) typically requires the tenant to pay base rent, property taxes, insurance, and maintenance costs separately.
Modified gross lease: A hybrid that allocates some expenses to each party, with the specific split defined in the lease.
The practical effect on total occupancy cost can be significant. A seemingly low base rent in a triple-net lease may result in higher total occupancy cost than a gross lease once taxes, insurance, and CAM charges are factored in.
Rent, CAM Charges, and Other Commercial Property Costs
In many commercial leases, rent is only part of what a tenant pays. The lease determines whether the tenant is also responsible for operating costs.
- Base rent: The core periodic payment due under the lease, typically expressed as dollars per square foot per month or year.
- Common area maintenance (CAM): Charges for the tenant’s proportionate share of costs to maintain shared areas, including lobbies, parking lots, landscaping, and building systems.
- Property taxes: In net leases, the tenant often pays a share of the property’s tax bill. Owners should verify how changes in assessed value affect the tenant’s contribution.
- Insurance: The tenant may be required to reimburse the owner for some portion of property insurance, in addition to carrying their own business and liability coverage.
- Utilities: Depending on the lease, utilities may be included in base rent, billed separately by the owner, or paid directly by the tenant to the utility provider.
CAM disputes are among the most common commercial landlord-tenant conflicts. The lease should define what expenses are in CAM, how the tenant’s share is calculated, whether management fees or capital expenditures are recoverable, and how estimated charges are reconciled at year-end.
Repairs and Maintenance Responsibilities
Commercial leases allocate repair and maintenance responsibilities between the parties in many different ways. There is no California statute that automatically assigns these duties the way the residential habitability rules do.
Typical commercial lease arrangements include:
- Tenant responsible for interior: The tenant maintains the interior of the leased space, including fixtures, floor coverings, and non-structural elements, while the owner handles the roof, exterior, and building structure.
- Tenant responsible for systems: In some leases, particularly net leases, the tenant is responsible for HVAC, plumbing, and electrical systems serving only the tenant’s space. A well-drafted lease addresses whether the tenant must maintain service contracts.
- Owner responsible for common areas: The owner typically maintains shared areas, parking facilities, and structural elements, recovering costs through CAM charges.
Disputes commonly arise over HVAC systems, roofs, and improvements made by prior tenants. The lease should identify which party owns tenant improvements after the lease ends, and which party is responsible for removing them.
Before signing a commercial lease, both parties should inspect the property’s existing condition and document it carefully. Ambiguities about who is responsible for a pre-existing condition tend to become costly disputes later.
Can a Commercial Landlord Enter the Property?
California Civil Code section 1954, which governs residential entries, requires at least 24 hours’ advance written notice before a landlord enters a residential unit. That rule does not automatically apply to commercial leases.
For commercial property, the right of entry is governed by the lease. A commercial lease typically gives the owner the right to enter for inspections, repairs, emergencies, and showings. It may or may not specify advance notice requirements.
Owners should review the lease before entering. Entering without the contractual right to do so, or in violation of notice provisions, can create liability for interference with business operations. Tenants who believe a landlord is entering in bad faith or in violation of the lease have contract-based claims to raise.
Commercial Lease Defaults and Breaches in California
Either party can default on a commercial lease. The consequences depend on the nature of the breach, the notice and cure provisions in the lease, and applicable California law.
Common Tenant Defaults
- Failure to pay rent or other required charges on time.
- Using the premises for a purpose not permitted by the lease.
- Making unauthorized alterations or improvements.
- Failing to maintain required insurance.
- Subletting or assigning without required landlord consent.
- Abandoning the premises before the lease ends.
Common Landlord Defaults
- Failing to make repairs or provide services required by the lease.
- Interfering with the tenant’s quiet enjoyment of the premises.
- Failing to deliver possession or a required improvement on time.
- Improperly applying or withholding the security deposit.
Notice and Cure
Most commercial leases require the non-defaulting party to give written notice before taking action. The defaulting party then has a specified period to cure. Cure periods vary: a monetary default may allow only three days to pay, while a non-monetary default may allow 30 or 60 days to cure.
Acting without following the lease’s required notice and cure process can weaken a party’s position, even when the other side is clearly in breach. Review the lease carefully before serving any default notice or taking any responsive action.
Commercial Evictions in California
When a commercial tenant fails to vacate after a valid termination or default, the owner must use the unlawful detainer process to recover possession. Self-help eviction, including changing locks or removing the tenant’s property, is illegal in California for commercial property.
The commercial eviction process under Code of Civil Procedure section 1161 begins with a proper notice. For unpaid rent, this is typically a three-day notice to pay or quit. For other defaults, it may be a three-day notice to cure or quit. Once the notice period expires without compliance, the owner files an unlawful detainer complaint in superior court.
Commercial unlawful detainer cases generally proceed on a shorter timeline than ordinary civil cases. After the complaint is filed, the tenant has five days to respond. If the tenant contests the eviction, the court schedules a hearing. Successful landlords receive a judgment for possession, enforced by a sheriff or marshal.
Commercial tenants facing eviction may raise defenses based on landlord breach, improper notice, or other contractual arguments. The outcome depends on the specific facts and the lease terms. A defective notice is one of the most common reasons commercial eviction cases are dismissed and must be restarted.
Commercial eviction is not governed by the same procedural rules as residential eviction. Residential protections like just cause requirements under AB 1482 do not apply to commercial tenancies.
Ending or Renewing a Commercial Lease
Commercial leases end at expiration, by mutual agreement, through exercise of a contractual termination right, or when a default leads to a lawful termination.
Renewal Options
Many commercial leases include an option to renew for one or more additional terms. Renewal options are valuable to tenants because they provide security of tenure. But renewal options must be exercised strictly: the notice period, delivery method, and deadline are all typically conditions of a valid exercise. Tenants who miss the exercise deadline often lose the option.
Holdover Tenancy
When a tenant continues to occupy the premises after the lease expires without a new agreement, a holdover tenancy arises. California law may treat this as a month-to-month tenancy, but the lease may specify different holdover terms, including a penalty rent of 150 percent or more of prior base rent. Owners and tenants should address holdover well before the lease expires.
Early Termination and Notice
Some leases allow either party to terminate before the natural expiration upon specified conditions or by paying a termination fee. Whether the lease contains such a right, and what it costs to exercise it, depends entirely on the negotiated terms. Neither party has a statutory right to walk away from a commercial lease before it ends without justification.
Assignment and Subleasing of Commercial Property
A commercial tenant may want to transfer its lease interest, either by assigning the full lease to a new tenant or by subleasing some or all of the space.
Assignment: The original tenant transfers its entire leasehold interest to a new party. Unless the lease releases the original tenant, most assignments do not relieve the original tenant of its obligations. The assignee steps into the original tenant’s position.
Sublease: The original tenant retains its relationship with the landlord and grants a new tenant the right to occupy some or all of the space. The original tenant remains liable under the original lease.
Most commercial leases require landlord consent before an assignment or sublease. The lease often specifies the standard for consent: some leases allow the landlord to withhold for any reason; others require that consent not be unreasonably withheld. California law, under Civil Code section 1995.010 and following, provides some default rules when the lease is silent on the reasonableness standard.
Tenants selling a business often need to assign or sublease the premises as part of the transaction. Reviewing transfer restrictions well before a sale or restructuring is essential.
Zoning and Permitted Use of Commercial Property
A commercial lease gives a tenant the right to use the premises as between the parties. But it does not override local zoning rules. A business permitted under the lease may still require a conditional use permit, a business license, or local planning approval before operating.
Common issues include:
- A zoning designation that allows retail but not restaurant or food-service operations, requiring a conditional use permit for a tenant’s intended use.
- A change in ownership or business type that triggers a new permit requirement, even within the same leased space.
- An expansion of operations that requires a building permit or zoning variance.
- Historic designations, specific plan areas, or local overlay zones that impose additional conditions.
Owners and tenants should verify the intended use is consistent with local zoning before signing the lease. Lease rights cannot cure a zoning violation. For complex land-use questions, Kassouni Law’s California land use practice advises property owners on permitting, entitlements, and use disputes.
Common Commercial Real Estate Disputes in California
Most commercial real estate disputes center on the lease. Common categories include:
- Unpaid rent and CAM charges: Tenants may dispute the accuracy of operating expense reconciliations or challenge charges they believe exceed what the lease permits.
- Repairs and maintenance: Disagreements over which party is responsible for a specific repair are among the most frequent commercial lease disputes.
- Property damage: Damage caused by leaks, fire, or structural failures often produces disputes about responsibility, insurance obligations, and rent abatement.
- Unauthorized alterations: Improvements a tenant makes without landlord consent can give rise to default claims and disputes about who pays for restoration.
- Lease termination and holdover: Whether a lease was validly terminated, and who bears the costs of a holdover, are frequently litigated issues.
- Assignment and sublease disputes: Whether a landlord properly withheld consent for a transfer is a common point of contention.
- Breach of contract: Either party may claim the other failed to perform a material obligation, ranging from failure to deliver a build-out to failure to provide promised services.
Commercial real estate disputes may be resolved through direct negotiation, mediation, arbitration, or court litigation. The lease often specifies the dispute resolution method, including whether arbitration is mandatory and how attorney fees are allocated.
When Should a Commercial Property Owner or Tenant Talk to a Lawyer?
Many commercial real estate matters are complex enough that legal advice is worth obtaining before a dispute escalates. Situations where early legal review makes a significant practical difference include:
- Negotiating a new commercial lease with significant financial obligations or a long term.
- Reviewing a lease that contains unusual default, termination, or personal guarantee provisions.
- Receiving a default or termination notice from the other party.
- Disputing CAM charges, operating expense reconciliations, or other cost recoveries.
- Dealing with a significant repair or maintenance dispute.
- Considering a lease assignment or sublease in connection with a business sale or restructuring.
- Facing a commercial eviction or intending to pursue one.
- Addressing a lease interpretation dispute before it reaches litigation.
- Dealing with zoning or land-use issues affecting the permitted use of the property.
Complex ownership or title questions involving commercial property may also involve Kassouni Law’s California property rights practice.
Schedule a Consultation With Kassouni Law
Commercial real estate law in California does not impose the same fixed protections that residential tenancy law does. The lease defines most of the parties’ rights. Local zoning and California statutes fill gaps and set limits, but the negotiated agreement typically controls.
Both property owners and tenants benefit from understanding the terms of their lease before a problem arises, not after. When a significant issue develops, getting legal advice early usually leads to better outcomes than waiting until a dispute has escalated into litigation.

Frequently Asked Questions
What rights do commercial tenants have in California?
Commercial tenants have the rights their lease provides: to occupy the premises for the permitted use, receive agreed improvements or services, and enforce favorable lease terms. California does not extend residential protections, such as rent caps or implied habitability warranties, to commercial tenants. The lease is the primary source of a commercial tenant’s rights.
What rights do commercial property owners have in California?
Commercial property owners have the right to collect rent, enforce lease terms, access the property as the lease permits, recover costs allocated to tenants, address defaults, and pursue eviction when a valid basis exists. Under Civil Code section 1951.2, owners may recover damages after a breach, subject to a duty to mitigate by attempting to relet the property.
Are commercial tenants protected by California residential landlord-tenant laws?
No. California’s residential protections, including AB 1482 rent caps, the Civil Code section 1941 habitability warranty, the Civil Code section 1950.5 deposit limits, and the 24-hour entry notice rule, apply to residential tenancies, not commercial ones. Commercial tenants and their landlords negotiate their own terms. The lease governs the relationship.
Who is responsible for repairs in a California commercial lease?
Repair responsibility in a commercial lease is determined by the lease terms, not by a statutory default rule. Most leases allocate interior maintenance to the tenant and major structural, roof, and exterior repairs to the owner. Net leases often shift more maintenance responsibility to the tenant, including mechanical systems. Disputes typically arise when the lease is ambiguous about a specific item or system. Review the lease carefully, and document property conditions before taking occupancy.
Can a commercial landlord evict a tenant in California?
Yes, through the court unlawful detainer process under Code of Civil Procedure section 1161. The owner must first serve a valid notice, such as a three-day notice to pay rent or quit. If the tenant does not comply, the owner files an unlawful detainer complaint in superior court. The court determines whether the eviction is legally justified. Self-help eviction, such as changing locks or removing a tenant’s property without a court order, is illegal regardless of the tenant’s conduct.
How is a commercial lease different from a residential lease?
Commercial leases are negotiated contracts with few statutory guardrails. The parties can agree to almost any allocation of rights, costs, and obligations. California’s residential tenancy laws, including rent control, habitability protections, deposit limits, and mandatory notice periods, do not apply. Commercial leases are typically longer, more complex, and more favorable to the party with greater negotiating leverage. Both owners and tenants benefit from reviewing commercial lease terms with legal counsel before signing.
