California Security Deposit Law: A Stockton Landlord's Guide (2026)

What Stockton and Central Valley Landlords Must Know About Security Deposits

Under California law, a landlord can charge a maximum security deposit equal to one month's rent for both unfurnished and furnished units, whether or not the tenant has a pet. Once a tenant moves out, the landlord has 21 calendar days to either return the full deposit or provide an itemized statement showing exactly what was deducted and why. At M&S Property Management, we handle every deposit in Stockton, Manteca, Tracy, Lathrop, Modesto, and Lodi the same way: documented move-in condition, itemized deductions only for real damage, and the balance returned on time, every time.

The one-month cap applies regardless of whether the unit is furnished, a change from the old law that allowed higher deposits for furnished rentals and pet owners. That means a $2,000/month home in Stockton can carry, at most, a $2,000 security deposit, no matter how many pets or how much furniture is involved. Landlords can no longer collect a separate, larger "pet deposit" on top of that cap. Any lease that tries to charge more than one month's rent as a deposit is not enforceable for the excess amount, and a tenant can demand the overage back.

There is one notable exception: a "small landlord," defined as a natural person who owns no more than two rental properties with a combined total of no more than four units, can charge up to two months' rent as a deposit on an unfurnished unit. Even then, the landlord must still meet strict conditions, including providing the tenant an initial inspection and written notice of the higher deposit amount. Most owners working with M&S fall under the standard one-month cap, and we make sure every lease we manage reflects the correct limit for that owner's situation.

When a tenant moves out, the clock starts immediately: landlords have 21 calendar days to send back the deposit, minus any lawful deductions, along with an itemized statement and copies of receipts or invoices for repairs over $125. Lawful deductions are limited to unpaid rent, cleaning needed to return the unit to the condition it was in at move-in, repairing damage beyond normal wear and tear, and, if the lease allows it, restoring or replacing furnishings. Normal wear and tear, like faded paint, worn carpet in high-traffic areas, or small nail holes, cannot be deducted; that cost is the landlord's to absorb. Missing the 21-day deadline or deducting for ordinary wear and tear can expose a landlord to a lawsuit for the deposit amount plus, if a court finds the withholding was done in bad faith, up to twice the deposit in statutory damages.

Good documentation is what protects both sides. A detailed move-in checklist with dated, timestamped photos or video, signed by the tenant, is the single best defense against a disputed deduction. Without it, disputes over what was already damaged versus what happened during the tenancy usually favor the tenant. Owners in Stockton, Manteca, Tracy, Lathrop, Modesto, and Lodi who self-manage often lose deposit disputes not because the damage wasn't real, but because there was no record proving the unit's condition at move-in.

At M&S Property Management, we handle security deposits from move-in to move-out: photo-documented condition reports, deposits held and accounted for correctly, itemized statements sent well within the 21-day window, and clear records if a deduction is ever disputed.
