California Security Deposit Law: Civil Code 1950.5 Explained (2026)

Your landlord collected your deposit on day one and has held it ever since. California law tells them exactly what they can keep, how long they have to return it, and what happens if they ignore those rules. Most tenants don't know the specifics — and landlords count on that.

Here is what California security deposit law actually says.

The Governing Statute: California Civil Code Section 1950.5

Everything about residential security deposits in California runs through Civil Code § 1950.5. This statute covers the maximum amount a landlord can collect, the deadline for returning it, what deductions are legal, the evidentiary standards a landlord must meet to justify those deductions, and the penalties they face for willful violations.

Three recent bills have significantly strengthened tenant protections under this statute: AB 12 (effective July 1, 2024), AB 2801 (effective April and July 2025), and AB 414 (effective January 1, 2026). Understanding all three is essential because older blog posts and generic templates almost certainly don't reflect the current law.

Deposit Limits Under AB 12

Before AB 12, California landlords could charge up to two months' rent for an unfurnished unit and three months' rent for a furnished one. AB 12 eliminated that distinction entirely.

As of July 1, 2024, the maximum security deposit is one month's rent — regardless of whether the unit is furnished or unfurnished.

Every dollar you were charged counts toward this cap. If your landlord collected a standard deposit plus a "pet deposit," "key deposit," or "cleaning fee" at move-in, California law treats all of those as part of the same security deposit. The combined total cannot legally exceed one month's rent.

There is one narrow exception: a landlord who is an individual person (or an LLC composed entirely of individual people) and who owns no more than two residential rental properties containing no more than four total units combined may still charge up to two months' rent. But even this exception has a hard limit — active-duty military service members can never be charged more than one month's rent, full stop.

One more thing that cannot appear in any California lease: the words "non-refundable deposit." Civil Code § 1950.5 expressly prohibits labeling a security deposit as non-refundable. That clause is illegal and unenforceable regardless of what your lease says.

The 21-Day Return Deadline

This is the most commonly violated rule in California security deposit law, and it is also the one most useful to tenants.

Under Civil Code § 1950.5(g), a landlord must either return your full deposit or send you an itemized accounting within 21 calendar days of you vacating the unit and surrendering possession.

The 21-day clock starts the moment you hand over the keys. The landlord's obligation has two parts:

1. Return any money not being withheld, and
2. Provide a written, itemized statement explaining every deduction, including the exact dollar amount and reason for each.

If the landlord misses this deadline, the consequences are severe. They generally forfeit the legal right to deduct anything from your deposit. A landlord who sits on your deposit past day 21 — without sending you a compliant itemized statement — has handed you the foundation for a bad-faith claim.

AB 2801: The Photo Requirement That Changes Everything

AB 2801 is arguably the most significant shift in California security deposit law in decades. It addresses the core problem with most deposit disputes: without photos, it's one person's word against another's.

The law creates mandatory photographic requirements for landlords:

• For tenancies beginning on or after July 1, 2025: The landlord must photograph the unit immediately before the tenant moves in, establishing a verified baseline of the property's condition.
• For all tenancies as of April 1, 2025: The landlord must photograph the unit immediately after the tenant vacates — before any cleaning or repairs begin — and again after those repairs are completed.

When the landlord sends the itemized statement within the 21-day window, they must include this complete sequence of photos alongside invoices and receipts.

If the landlord fails to provide the required photos, they lose the right to make deductions for the items that lack photographic documentation. This is not a technicality — it is a hard statutory requirement. A landlord who cannot produce the pre-repair and post-repair photos for a $800 cleaning charge legally cannot collect that $800.

For tenants, this cuts both ways. If a landlord sends you an itemized statement with no photos attached, the deductions tied to cleaning or repairs are presumptively invalid. You can challenge them in writing by citing AB 2801 non-compliance directly.

AB 414: Electronic Returns (2026)

Effective January 1, 2026, if you paid your rent or security deposit electronically, your landlord is legally required to return your deposit electronically — to a bank account you designate. Paper checks are no longer the automatic default.

The only way a landlord can issue a paper check when electronic payment was previously used is if both parties sign a written agreement to do that. A verbal promise or an email isn't enough.

AB 414 also clarifies the roommate situation: if multiple tenants are on the lease, the landlord must issue a single joint refund made payable to all adults on the agreement simultaneously. If roommates want separate fractional refunds sent to different accounts, they need to submit a unanimous written agreement to the landlord before the refund is issued.

What Landlords Can Legally Deduct

Civil Code § 1950.5 permits deductions only in four specific categories:

1. Unpaid rent — money owed for rent you didn't pay
2. Cleaning costs — but only to restore the unit to the exact level of cleanliness it was in when you moved in, not to upgrade it to a professional standard
3. Damage beyond normal wear and tear — actual damage caused by you, your guests, or your pets
4. Replacement of personal property — only if the lease agreement specifically authorizes this use of the deposit

The "normal wear and tear" exclusion is where most disputes concentrate. Civil Code § 1950.5(e) explicitly prohibits deductions for ordinary deterioration that results from standard use of the unit over time. Scuffed baseboards, small nail holes from hanging pictures, and faded paint from sun exposure are landlord expenses, not tenant liabilities.

If the landlord charges for damage to something that already had limited useful life remaining — say, carpet that was already eight years old with a standard lifespan of ten years — they can only charge for the remaining useful life, not full replacement cost. At eight years on a ten-year carpet, that's a maximum of 20% of replacement cost.

California Security Deposit Rules: The Tenant's Enforcement Checklist

Here is a quick-reference summary of the rules that matter most:

The bad-faith penalty in the last row matters enormously. If a judge determines that a landlord deliberately and intentionally withheld your deposit in violation of the law, you can be awarded up to twice the original deposit amount in addition to getting the deposit itself back. On a $2,500 deposit, that's a potential $7,500 judgment.

Your Statutory Right to a Pre-Move-Out Inspection

One right that many tenants never exercise: under Civil Code § 1950.5(f), once you give notice to vacate or receive a termination notice from your landlord, they are required to notify you in writing of your right to a preliminary inspection.

This inspection must occur within the two weeks before you move out. After the inspection, the landlord must give you a written list of anything they intend to call a deficiency. That list then gives you the chance to fix those items yourself before you leave — and prevent the landlord from later inflating the repair costs on the final itemized statement.

Critically, if the landlord's preliminary inspection list does not mention something, they are generally barred from charging for it later (unless the damage occurred after the inspection or was concealed by your belongings at the time).

Request the pre-move-out inspection in writing. It's your legal right, and it removes one of the landlord's primary tools for surprise deductions.
