How to Break a Lease in California Without Losing Your Deposit

What You'll Need

• The full signed lease, including any addenda — find the end date, the early termination or buyout clause, and any stated re-letting fee.
• Your tenancy type in writing: fixed-term through a specific date, or month-to-month. Month-to-month tenants must give at least 30 days' written notice under California Civil Code Section 1946.1 (Castelblanco, undated).
• The security deposit amount as written on your lease or receipt. Under AB 12, signed October 11, 2023, deposits in California are limited to one month's rent for most rentals and two months' rent for rentals by small landlords beginning July 1, 2024 (California Department of Real Estate, reproduced by UC Berkeley Student Legal Services, 2024).
• Move-in condition evidence: dated photos or video of every room, plus any move-in checklist the landlord gave you.
• A written rent payment record showing you are current through your intended last day.
• The landlord's or agent's legal name and mailing address for serving notice — the address rent is sent to is usually the one to use.
• A forwarding address in writing, so the itemized statement and any refund reach you.
• Documentation for a statutory early exit, if it applies: a restraining order, police report, or documentation from a qualified third party is what Civil Code Section 1946.7 requires from survivors of domestic violence, sexual assault, stalking, human trafficking, and elder or dependent adult abuse (National Housing Law Project, 2016).

Step-by-Step Process

1. Before you give any notice, read the early termination clause. If your lease names a flat buyout amount and a notice period, that clause — not the default statute — usually sets the cheapest, fastest path, so price it against the remaining months of rent.
2. Confirm the notice you owe. If you are month-to-month, California Civil Code Section 1946.1 requires at least 30 days' written notice from the tenant; landlords may owe 30 or 60 days depending on how long you have lived there (Castelblanco, undated). If you are mid-lease, notice alone does not end your rent obligation — it only sets the date you hand back possession.
3. Check for a statutory exit within the first week. Civil Code Section 1946.7 lets survivors covered by the statute end a lease early without owing additional rent using a 14-day notice plus qualifying documentation (National Housing Law Project, 2016); the Legislature made that early termination available without penalty effective January 1, 2016 (San Diego County Bar Association, 2016).
4. Send written notice, dated, at least the full notice period before your move-out date. State your last day, your forwarding address, and that you will return all keys. Send it by a method that produces a delivery record and keep a copy.
5. Put a mitigation proposal in the same thread. Under Civil Code Section 1951.2 a landlord may recover unpaid future rent only after acting reasonably to mitigate damages (Higgs Fletcher & Mack, undated), and California landlords are required to try to find a replacement tenant when a renter leaves before the lease ends (Caretaker, undated). Offer showings, photos, and referrals in writing so the re-rental record is yours too.
6. Ask the landlord in writing, roughly two weeks out, whether they will do a walkthrough before you move out. If they will, attend it, take your own photos, and fix the specific items they name before your last day.
7. On your last day, document and return keys together. Photograph or film every room, closet, appliance and floor with a timestamp, then return all keys and remotes and get written confirmation of the date — the 21-day deposit clock runs from when you move out and return keys (Castelblanco, undated).
8. Diary the 21st day. If no refund and no itemized statement arrives, send a written demand citing Civil Code Section 1950.5. Under AB 2801, a landlord who in bad faith fails to comply with the deposit return requirements is not entitled to deduct any amount from the deposit (California Department of Real Estate, 2025). If the demand is ignored, small claims court is the usual next step for a deposit dispute.

Sample Script

Use this when you have a fixed-term lease, no buyout clause, and you need the landlord to engage with re-renting rather than simply holding you for the remaining months.

Email: giving notice and proposing a replacement tenant

Hi [Landlord],

I'm giving written notice that I will vacate the one-bedroom at [address] in Sacramento on March 31 and return all keys that day. My lease runs through July 31 at $2,400 a month for this unit.

I understand that under California Civil Code Section 1951.2 you may claim unpaid rent for the remaining term, offset by the rental loss that could reasonably have been avoided. I want to keep that figure as low as possible: I'll keep the unit show-ready, pay April rent while you market it, and I've attached contact details for two people who want to apply.

Please confirm in writing the date you'll treat the tenancy as ended. My forwarding address for the deposit is [address].

Common Mistakes to Avoid

• Giving notice verbally. A month-to-month tenant who tells the landlord by phone has no proof of the date, and California Civil Code Section 1946.1 calls for at least 30 days' written notice (Castelblanco, undated) — you can end up owing another full month's rent you thought you'd ended.
• Moving out but hanging on to a key or a garage remote. The 21-day deposit deadline runs from when you move out and return keys (Castelblanco, undated), so an unreturned key can push the clock back by weeks and muddy any later claim.
• Treating the deposit as prepaid rent. Telling a landlord to "just use the deposit" for your last month does not settle anything: the deposit is still subject to the Civil Code Section 1950.5 itemization process, and remaining-term rent is handled separately under Section 1951.2.
• Walking away silently and never putting a mitigation offer in writing. Section 1951.2 reduces the landlord's claim by the rental loss the tenant proves could reasonably have been avoided (Schorr Law, undated) — with no emails, no referrals and no showing offers, you have nothing to prove it with.
• Accepting a deduction with no itemized statement. If the landlord keeps part of the deposit and sends only a dollar total, ask in writing for the itemization; under AB 2801, a bad-faith failure to comply with the return requirements costs the landlord the right to deduct anything (California Department of Real Estate, 2025).
• Agreeing to a buyout by text and nothing else. Without a signed mutual release naming the end date and stating you owe no further rent, a landlord can later bill you for the balance of the term.
