The Most Common Landlord Mistake in California
If there’s one area where self-managing landlords get into trouble, it’s with security deposits. California’s laws are very specific, and even small mistakes can cost landlords thousands. We see it all the time — a landlord acts in good faith but fails to document properly or misses the 21-day return window, and the tenant wins in small claims court.
Here’s what every landlord should know:
- How Much Can Be Charged:
- Unfurnished units – up to two months’ rent.
- Furnished units – up to three months’ rent.
- Starting July 1, 2024, new law limits deposits to one month’s rent for most landlords, though small “mom-and-pop” owners (two or fewer rentals) are exempt and can still collect up to two months.
- No Such Thing as a “Non-Refundable Deposit”: Every deposit must be returnable and properly accounted for.
- Funds Must Be Held Properly: Deposits should be treated as trust funds — not mixed with personal or business accounts.
- Return Timeline: Deposits must be returned within 21 days after move-out, along with an itemized breakdown of any deductions.
- Allowable Deductions: Only for unpaid rent, cleaning (to restore move-in condition), or repairs beyond normal wear and tear.
- Receipts Required: Any deduction over $125 must include receipts or invoices. If work isn’t completed yet, the landlord must provide written notice and supply receipts later.
Why This Matters
Security deposit disputes are one of the top reasons landlords get sued. Courts favor documentation — and without clear proof, the tenant almost always wins.
At Leasing Alert, we go above and beyond simple photos and paper checklists. We use 3D property tours at move-in and move-out to document the condition of every unit in detail. This allows us to show an exact before-and-after comparison, protecting both the landlord and tenant from misunderstandings.
Our process includes:
- Full 3D property scans before and after each tenancy to verify the exact condition.
- Detailed move-in and move-out inspections with timestamped photos.
- Receipts and documentation for all deductions.
- On-time deposit returns and clear communication with tenants.
This level of documentation not only protects owners legally but also builds trust with tenants. When tenants feel treated fairly, they’re more likely to take care of the property and renew their lease.
