How It Works
State law decides how much a landlord can demand up front, how quickly the money must come back, and what can lawfully be subtracted from it. This tool surfaces the 2026 rules for your state in one place, so renters and landlords alike can act on the actual statute instead of guesswork. Because deposit caps and return windows differ sharply from one state to the next and get revised over time, having the current figures matters for steering clear of disputes.
Behind the result sits a database of 2026 landlord-tenant statutes. After you pick a state, the calculator looks up its deposit ceiling, which most states frame as a multiple of monthly rent such as 1.5x or 2x, and applies that multiple to the rent you entered to produce the maximum lawful deposit. The return deadline is taken straight from the statute, and the deduction summary reflects the grounds states commonly allow: unpaid rent or documented damage that goes beyond ordinary wear and tear.
Several states set separate caps for furnished units or for elderly tenants, so it pays to verify those carve-outs against your own circumstances. Disputes over deductions most often trace back to thin move-in and move-out records, which is why dated photos and video of the unit's condition are worth the few minutes they take. The figures here are general guidance; tangled cases warrant a lawyer who handles landlord-tenant matters.
Example: Renting a 2-bedroom apartment in California in 2026
- 1 Input the monthly rent: $2,500. Select 'California' as the state.
- 2 In California for 2026, the maximum security deposit for an unfurnished residential property is typically 2 times the monthly rent. For a furnished property, it's 3 times the monthly rent. Assuming an unfurnished apartment, the calculation is $2,500 (monthly rent) * 2 = $5,000. Landlords must return the deposit within 21 calendar days after the tenant moves out.
- 3 The maximum security deposit for this California apartment in 2026 is $5,000.
- 4 The landlord must return your security deposit within 21 days of you vacating the property. Permissible deductions include unpaid rent, cleaning costs to return the unit to its original cleanliness (excluding ordinary wear and tear), and repair costs for damages beyond normal wear and tear. You are entitled to an itemized statement of deductions if any are made.
