California Security Deposit Law — Tenant Rights Guide

The 21-Day Rule (Civil Code § 1950.5(h))

Within 21 calendar days after you vacate, your landlord must do one of two things:

Return your entire deposit, OR
Mail or deliver a written itemized statement explaining every deduction, plus the remaining balance.

There is no grace period and no exception for "the landlord was busy." The clock starts the day you vacate.

No statement within 21 days? The landlord forfeits the right to make any deductions and must return the full deposit — plus may owe you 2× the deposit in statutory damages if a court finds bad faith.

What Landlords Can and Cannot Deduct

Allowed (§ 1950.5(b))

Unpaid rent
Cleaning costs if you left the unit dirtier than move-in condition
Repair of damage beyond normal wear and tear
Restoration of unpermitted alterations

Not allowed (§ 1950.5(e))

Normal wear and tear — scuffs, minor carpet wear, faded paint
Damage that pre-existed your tenancy
Carpet replacement if the carpet was already old at move-in
Full-room repaints for minor marks

The 2× Bad-Faith Damages Multiplier (§ 1950.5(m))

If a court finds the landlord retained your deposit in bad faith, you are entitled to your actual damages plus up to 2 times the original deposit amount as a statutory penalty.

Example calculation

Deposit:                      $2,000
Landlord's deductions:        $1,800  (carpet + cleaning + paint)
Deductions tenant agrees to:    $200  (move-out cleaning was fair)
Wrongfully retained:          $1,600

If court finds BAD FAITH and awards full 2×:
  $1,600 actual  +  $4,000 statutory  =  $5,600 total

If court awards 1×:
  $1,600 actual  +  $2,000 statutory  =  $3,600 total

If no bad faith finding:
  $1,600 only

What courts have found to be bad faith

No response at all past the 21-day deadline
Provably false deductions (claiming repairs with no receipts, charging for pre-existing damage)
Charging for normal wear and tear after being told it is not allowed
Refusing to return the undisputed portion while disputing the rest

What is generally not bad faith

Honest calculation mistakes, promptly corrected
Late return with a credible explanation
An itemized statement on time, even if individual deductions are later reduced

Deposit Limits (§ 1950.5(c))

For deposits demanded on or after July 1, 2024, a landlord generally cannot charge more than 1 month's rent as a security deposit, whether the unit is furnished or unfurnished (§ 1950.5(c)(1)). A limited exception lets a small landlord — a natural person (or an LLC owned entirely by natural persons) who owns no more than two residential rental properties with no more than four units total — collect up to 2 months' rent (§ 1950.5(c)(5)). You can sue for any excess immediately — you don't need to wait until move-out.

Demand Letter vs. File Directly

Deposit under $1,500, disorganized landlord — Send a demand letter first. Many settle the moment you cite § 1950.5(m) and the 2× exposure.
Deposit $1,500–$12,500, clear bad faith — File directly in small claims.
Deposit over $12,500 — Small claims is capped at $12,500 (CCP § 116.221). You need limited-civil court or an attorney.
Corporate property manager — Demand letter first; they often settle to avoid precedent.

Filing in Small Claims Court

California small claims courts handle deposit cases up to $12,500. Filing fee is $30–$75. You do not need a lawyer.

Attorney Fee Shifting

Civil Code § 1950.5 does not include fee-shifting for prevailing tenants. Court costs (filing fee, service fee) shift to the losing party under CCP § 1032, but not attorney's fees.

Frequently Asked Questions

How long does my landlord have to return my security deposit in California?

Within 21 calendar days after you move out, your landlord must either return your full deposit or mail you a written itemized statement of every deduction along with the remaining balance (California Civil Code § 1950.5(h)). There is no grace period.

What can a landlord legally deduct from my security deposit?

Only unpaid rent, cleaning to return the unit to its move-in condition, repair of damage beyond normal wear and tear, and restoring unpermitted alterations (§ 1950.5(b)). Normal wear and tear and pre-existing damage cannot be deducted (§ 1950.5(e)).

What happens if my landlord misses the 21-day deadline?

The landlord forfeits the right to make any deductions and must return the full deposit. If a court finds the deposit was retained in bad faith, you may also recover up to two times the deposit amount as statutory damages (§ 1950.5(m)).
