California Civil Code Section 1950.7 governs security deposits on non-residential leases in California: it defines what counts as a deposit, limits what a landlord may deduct, sets return deadlines, and provides a modest penalty when a landlord withholds funds in bad faith. It gives commercial tenants far fewer protections than the residential deposit statute, and it leaves most of the important terms to the lease itself.1California Legislative Information. California Civil Code CIV 1950.7
What the Statute Treats as a Deposit
Under Section 1950.7, a commercial security deposit is any payment whose primary purpose is to guarantee the tenant’s performance of its obligations under a non-residential lease.1California Legislative Information. California Civil Code CIV 1950.7 Advance rent paid to secure the lease is treated separately and is not a deposit under the statute.
The landlord holds the deposit on the tenant’s behalf rather than as the landlord’s own money. If the landlord runs into financial trouble, the tenant’s claim to the deposit has priority over every creditor of the landlord except a trustee in bankruptcy.1California Legislative Information. California Civil Code CIV 1950.7
How Much a Landlord Can Demand
There is no statutory cap. Unlike residential leases, which are generally limited to one month’s rent for the deposit, Section 1950.7 sets no maximum on commercial deposits.2California Legislative Information. California Code Civil Code CIV 1950.5 A landlord can require three months, six months, or more. The number is a product of negotiation and depends on the tenant’s financials, the length of the lease, the cost of any tenant improvements the landlord funds, and market conditions.
For tenants, the practical takeaway is that the deposit amount is negotiable. Strong financials or an operating history can support a lower deposit, or a substitute such as a letter of credit or surety bond in place of cash.
What a Landlord Can Deduct
Section 1950.7 limits deductions to three categories: unpaid rent, repair of damage the tenant caused to the premises, and cleaning at the end of the tenancy. The landlord can claim only amounts that are reasonably necessary for these purposes.1California Legislative Information. California Civil Code CIV 1950.7 Upgrading the space for the next tenant, or paying for improvements unrelated to the departing tenant’s damage, is not on the list.
There is an important wrinkle. A California Court of Appeal decision interpreting Section 1950.7 held that the lease must state the deposit can be used for rent defaults, damage repairs, or cleaning. If the lease is silent on the deposit’s purpose, the landlord may not be able to make deductions at all, even for legitimate damage. Lease drafting matters on both sides of the table.
Section 1950.7 also does not mention “normal wear and tear.” That phrase appears in the residential statute, Section 1950.5, but not here. Reasonableness still constrains what a landlord can charge for repair of ordinary deterioration, but the explicit residential protection does not have a direct counterpart on the commercial side, so the lease language about the condition of the premises at move-out carries more weight.
When the Deposit Must Come Back
The return deadline depends on the size of the deposit relative to the rent and the type of claim the landlord is making.
The 30-Day Default
If the landlord is deducting for property damage or cleaning, the balance must be returned no later than 30 days after the landlord gets possession of the premises. The same 30-day deadline applies when the only claim is unpaid rent and the deposit is no more than one month’s rent plus last month’s rent.1California Legislative Information. California Civil Code CIV 1950.7 The parties can agree on a shorter period; 30 days is the outer limit.
The Two-Week Rule for Larger Deposits
When the deposit exceeds one month’s rent plus last month’s rent and the landlord’s only claim is unpaid rent, a split timeline applies. The portion exceeding one month’s rent must be returned within two weeks of the landlord receiving possession. The remainder must be returned or accounted for within the standard 30-day window.1California Legislative Information. California Civil Code CIV 1950.7
No Itemized Statement Required
Section 1950.7 says the deposit must be “returned or accounted for,” but it does not prescribe a format. There is no statutory requirement to itemize deductions, attach receipts, or follow the detailed accounting procedures that apply to residential deposits under Section 1950.5. A commercial tenant who wants an itemization needs to write that requirement into the lease.
If the Property Is Sold or the Landlord Changes
When the landlord sells the property, dies, or otherwise transfers their interest, the landlord or their agent has to do one of two things within a reasonable time. They can transfer the remaining deposit to the new owner and notify the tenant by personal delivery or certified mail with the new owner’s name and address and any claims already made against the deposit. Or they can return the remaining balance to the tenant.1California Legislative Information. California Civil Code CIV 1950.7 Either option releases the original landlord from further liability.
A new owner who receives a transferred deposit takes on all the rights and obligations of the original landlord under the statute.1California Legislative Information. California Civil Code CIV 1950.7 If the original landlord fails to transfer the deposit or notify the tenant, the original landlord remains on the hook.
What a Tenant Can Recover for Bad Faith
A landlord who keeps a deposit or any part of it in bad faith is liable for statutory damages of up to $200 on top of actual damages.1California Legislative Information. California Civil Code CIV 1950.7 The $200 cap is low. The meaningful recovery is actual damages, which can include the wrongfully withheld deposit itself along with interest.
How the Commercial Rules Differ From Residential
Readers familiar with Section 1950.5 should not assume its protections carry over. The two statutes diverge on several points:
- Residential deposits are generally capped at one month’s rent; commercial deposits have no cap.
- Residential landlords must provide an itemized accounting with receipts; commercial landlords are not required to by statute.
- The residential statute prevents deductions for normal wear and tear; the commercial statute does not include that language.
- Bad faith retention exposes a residential landlord to up to twice the deposit amount; the commercial cap on statutory damages is $200.
The lighter framework reflects the legislature’s expectation that commercial parties will negotiate their own protections. In a dispute, that is exactly what happens: the lease language usually decides more than the statute.
Why the Lease Does More Work Than the Statute
Section 1950.7 is a floor. Courts have recognized that commercial parties can modify its default rules by agreement, which cuts both ways. A landlord can bargain for broader deduction rights; a tenant can bargain for a shorter return deadline, a required itemization with supporting documentation, interest on the held funds, or the right to substitute a letter of credit for cash. A clause spelling out how the deposit is handled on a sale is worth including as well, given how thin the statutory notice rule is.
Because Section 1950.7 leaves so many terms open, the deposit language written into the lease is where most of the real protection lives. Negotiating it carefully at the start of the tenancy is considerably less expensive than litigating over it at the end.
