Details
A California security deposit demand letter is a written request to your former landlord to return money they have kept past the 21-day deadline or deducted without a lawful basis. The rules it relies on are in Civil Code 1950.5: the 21-day return rule in subdivision (h), the photo rule in subdivision (g) and the bad-faith penalty in subdivision (m). For the underlying law, start with our California security deposit law guide.
Quick answer: Send a demand letter when 21 calendar days have passed since you moved out without a refund and itemized statement, or when the statement includes deductions that aren’t allowed or aren’t documented. The letter should state the deposit amount, your move-out date, the amount owed and why, cite Civil Code 1950.5(h) and 1950.5(m), which allows statutory damages of up to twice the deposit for bad-faith retention, and set a firm payment date before you file in small claims court.

When to send a California security deposit demand letter
There are three common triggers:
- Nothing arrived in 21 days. The landlord must send the itemized statement and any refund no later than 21 calendar days after you vacate (1950.5(h)(1)). Day 22 with no statement is the clearest case for a letter.
- The deductions don’t fit the law. Charges for ordinary wear and tear, defects that were there before you moved in, or cleaning beyond move-in condition are not allowed (1950.5(e)(2)(A) and (b)(3)). Professional cleaning is deductible only when reasonably necessary to restore move-in condition (1950.5(e)(2)(C)). Our guide to California security deposit deductions covers each category.
- The paperwork is missing. If repair and cleaning deductions total more than $125, the statement must come with receipts, invoices or the landlord’s own time and hourly rate (1950.5(h)(2) and (h)(4)(A)). Where deductions are taken for repairs or cleaning, photos taken under 1950.5(g) must be included too (1950.5(h)(2)(D)).
If the deductions are $125 or less, you have a separate step first: request the documentation in writing within 14 calendar days of receiving the statement. The landlord must provide it within 14 calendar days of your request (1950.5(h)(5)).
What the letter should say
Section 1950.5 does not prescribe a demand letter form. What makes a letter useful is that it lays out the facts a small claims judge will look at, so the landlord sees the case you would file. Include:
- Your name, the rental address and the landlord’s name.
- The amount of the deposit and when you paid it. Proof can be any credible evidence, such as a canceled check, receipt or the lease (1950.5(p)).
- The date you vacated and returned the keys, and the forwarding address you gave.
- What you received, if anything, and when.
- The amount you are demanding and the reason for each disputed item, tied to the statute.
- A reference to 1950.5(m): bad-faith retention can lead to statutory damages of up to twice the amount of the deposit, in addition to actual damages, and the landlord carries the burden of proving deductions were reasonable.
- A specific payment date and method. If you paid rent or the deposit electronically, you can ask for an electronic refund to an account you name (1950.5(h)(1)(A)(ii)).
- What you will do if the money doesn’t arrive: file in small claims court.
Keep the tone factual. Threats beyond filing a lawsuit add nothing and can hurt your credibility with a judge.
A worked example
This is hypothetical. Say you paid a $1,800 deposit and moved out on Monday, August 31, 2026. The 21-day deadline was Monday, September 21, 2026. On September 18 you received a statement returning $1,150 and keeping $650:
- $400 to repaint the whole unit, after a three-year tenancy with no marks beyond normal fading
- $250 for professional carpet cleaning “per lease,” with carpet showing only traffic wear
The statement came on time, but it has two problems. The deductions total $650, over $125, and neither invoices nor photos were attached. And both items describe ordinary wear and tear, which 1950.5(e)(2)(A) excludes. Your letter would demand the $650 and cite 1950.5(e)(2)(A), (e)(2)(C) and (h)(2).

How to deliver the letter
The goal is proof that the landlord received it and when. Practical options:
- Certified mail with return receipt to the address the landlord uses for notices or rent. The green card or tracking record is your proof.
- Email, if you and the landlord have communicated that way, sent at the same time as the mailed copy.
- Personal delivery, with a witness or a signed acknowledgment.
Keep a copy of the letter, the proof of delivery, your move-in and move-out photos, the lease and the itemized statement in one place. Those documents are your small claims case file.
Give a specific payment date, such as 10 or 14 days out. The statute doesn’t set one, so pick a date that is firm but gives the landlord time to receive the letter and respond.
What happens after you send it
One of three things usually follows:
- The landlord pays in full. Confirm receipt in writing and keep the record.
- The landlord offers part of it. You can accept, counter or decline. If the offer comes with a release or “payment in full” wording, read it before signing anything or cashing the check.
- The landlord ignores it or refuses. You can file in small claims court. Section 1950.5(o) expressly allows deposit suits there.
Small claims limits under Code of Civil Procedure 116.220, 116.221 and 116.231:
| Who is suing | Maximum claim |
|---|---|
| An individual | $12,500 |
| A business or other plaintiff | $6,250 |
| Any plaintiff, claims over $2,500 | No more than two per calendar year statewide |
In the example above, a $650 claim plus up to $1,300 in bad-faith statutory damages totals $1,950, well within the limit. Bad-faith damages are not automatic: the court decides whether the facts warrant them. Our California small claims guide and court fee waiver guide cover filing.
Questions people ask
Do I have to send a demand letter before suing for my deposit in California?
Section 1950.5 does not make a demand letter a condition of suing. It is still worth sending, because it gives the landlord a chance to pay and gives you a dated record for the judge.
How much can I sue my landlord for over a security deposit?
The wrongfully withheld amount plus, for bad-faith retention, statutory damages of up to twice the deposit (1950.5(m)). An individual can claim up to $12,500 in small claims court.
What should I do if my landlord never sent an itemized statement?
Send a demand letter citing 1950.5(h). A landlord who fails to comply with that subdivision in bad faith is not entitled to keep any amount of the deposit (1950.5(h)(7)).
Can I ask for receipts if the deductions were small?
Yes. If repair and cleaning deductions were $125 or less, request documentation within 14 days of getting the statement; the landlord has 14 days to provide it.
