Commercial lease deposit dispute — suing in California small claims court
Read the deposit and surrender clauses and quote them in your demand. Remember that if you sue through an LLC or corporation your small claims ceiling is $6,250, not $12,500.
General information about California procedure. We are not a law firm and cannot advise on your case.
Your deadline to file
4 years — Breach of written lease (Code Civ. Proc. § 337).
The 21-day rule and the double-damages penalty in Civil Code § 1950.5 apply to residential tenancies only. A commercial deposit is governed by the lease itself.
The rule that decides most of these cases
Commercial tenants do not get the residential protections. Whatever your lease says about the deposit is what governs, which makes the lease language the whole case.
What this kind of case is worth
Commercial deposit claims in California small claims court typically run from $1,000 to $6,250. Note the entity trap: if you sue through a corporation, LLC or partnership your ceiling is $6,250, not $12,500. An unincorporated sole proprietor or freelancer sues as an individual and keeps the higher limit.
| Amount you are claiming | Filing fee |
|---|---|
| up to $1,500 | $30 |
| over $1,500 up to $5,000 | $50 |
| over $5,000 up to $12,500 | $75 |
| More than 12 small claims filed in the past 12 months | $100 |
How to start
Before you file, you have to have asked the defendant to pay — the SC-100 asks you to confirm it. A written demand with a deadline does three useful things at once: it satisfies that requirement, it creates a dated record the judge can see, and quite often it ends the dispute without a filing fee.
If the letter does not work, file SC-100 with the small claims division of the Superior Court in the right county — generally where the defendant lives or does business, or where the deal was made or performed.
What to bring to the hearing
A small claims judge has minutes, not hours. Walk in with these, each one labelled, plus a copy for the judge and a copy for the other side.
- The lease and every amendment
- Proof of the deposit payment
- The move-out condition report and photographs
- Any itemized deduction statement from the landlord
- Restoration or repair invoices
- Correspondence about the surrender of the premises
What they will argue back
Expect one of these. Knowing which is coming is most of the preparation.
- They rely on a restoration clause requiring you to return the space to its original condition
- They claim unpaid common area charges
- They claim holdover rent
Serving the papers
Filing is not the hard part. Service of process is where self-represented cases most often come apart. The defendant has to be formally notified, you cannot do it yourself, and you must file proof that it happened on form SC-104 before the hearing. Use the sheriff, a registered process server, or any adult who is not a party to the case.
The hearing
You cannot bring a lawyer to argue for you at a California small claims hearing. Neither can the other side. That is the whole point of the forum: the rules are simplified so two people can explain a disagreement to a judge without needing representation. You may get advice from an attorney before and after, and lawyers are permitted on appeal — but on the day, it is you.
Common questions
Does the 21-day deposit rule apply to my shop lease?
No. Civil Code § 1950.5, with its 21-day deadline and its up-to-double-damages penalty, applies to residential tenancies. For a commercial lease, the deadline and the permitted deductions are whatever the lease provides, so the document is where the answer lives.
