Still Mailing Deposit Checks? California Just Changed the Rules on You
That stack of envelopes, stamps, and paper checks you keep on hand for move-outs? As of January 1, 2026, it may no longer be legally sufficient. California Assembly Bill 414 (AB 414) has flipped the default for security deposit returns: if your tenant paid rent or their deposit electronically, you are now required to refund the balance electronically too, unless both of you agree otherwise in writing. For Bay Area landlords juggling multiple move-outs a year, this is one of those quiet legislative changes that can create loud problems if it gets missed.
The good news is that compliance is very manageable once you understand the rules. In this guide, Kenny Realty — a trusted San Francisco Bay property management company serving the San Francisco Peninsula, Bay Area, and surrounding communities for more than 50 years — breaks down exactly what AB 414 requires, what it changes, and how landlords can adapt before their next move-out.
Key Takeaways
Electronic refunds are now the default: Starting January 1, 2026, if a tenant paid rent or a deposit digitally, the landlord must return the deposit balance electronically unless both parties agree otherwise in writing.
Paper checks require written consent: Refunds must go out via ACH, direct deposit, or digital transfer; mailing a check is only compliant if the tenant has agreed to it in writing.
Itemized statements can be emailed, with permission: Landlords may email deduction statements only if the tenant has provided prior written consent.
Multi-tenant refunds go out as one payment: Units with multiple adult tenants receive a single collective refund unless a written agreement says otherwise.
The 21-day deadline has not changed: California's strict timeline to return the deposit or provide itemized deductions remains fully in effect.
What AB 414 Actually Says
AB 414 amends California's security deposit framework under Civil Code Section 1950.5, the same statute that governs deposit limits, deductions, and return timelines. You can read the full statutory text on the California Legislative Information website.
The core logic is simple: money should return the way it arrived. If your tenant has been paying rent through a portal, ACH transfer, or another digital method, the state now expects their deposit refund to travel the same modern rails rather than reverting to a paper check in the mail.
What it means: The burden has shifted. Electronic return is the presumption, and paper is the exception that requires documented tenant consent. Landlords who continue mailing checks by default risk noncompliance even when the refund amount is correct and on time.
Real-world example: A South San Francisco duplex owner has a tenant moving out in March. The tenant paid rent through an online portal for three years. Under AB 414, the owner must refund the deposit balance via ACH, direct deposit, or another digital transfer. Dropping a check in the mail, as the owner has done for a decade, is only compliant if the tenant signed off on that method in writing.
The Four Core Requirements Every Landlord Must Know
1. Electronic Return Is the Default
If the tenant made any digital payment of rent or deposit, the refund must be issued via ACH, direct deposit, or another digital transfer. Written agreement from both parties is required to use a paper check instead. If your rent collection already runs through a modern portal, you are most of the way there; the refund side simply needs to match.
2. Itemized Statements Can Go Digital, with Consent
AB 414 allows landlords to email the itemized statement of deductions, but only with the tenant's prior written consent. Without that consent, the statement must still be delivered the traditional way. Smart landlords are now adding an electronic-delivery consent clause at lease signing so this question is settled long before move-out.
3. Multi-Tenant Refunds Are One Payment
For units with multiple adult tenants, the refund must be issued as a single payment made out to all tenants collectively, unless a written agreement states otherwise. Roommate households are common across the Peninsula, so this provision deserves attention. If departing roommates want split refunds, get that arrangement in writing during the tenancy, not after keys are returned.
4. The 21-Day Clock Still Rules Everything
AB 414 changed the how, not the when. Landlords still have 21 days after move-out to return the deposit or provide an itemized statement of deductions. Miss the deadline, and you face the same penalties as before, including potential liability for bad-faith retention. Careful move-out documentation, like the process outlined in Kenny Realty's move-out and notice-to-vacate guidelines, remains your best protection.
What it means: Electronic transfers actually make the 21-day deadline easier to hit. There is no mail delay, no lost check, and a clean digital timestamp proving exactly when the refund was sent.
How Bay Area Landlords Should Prepare
Update Your Lease Templates Now
Add two consent provisions to every new lease and renewal: one covering the refund method and one covering electronic delivery of itemized statements. Collecting these signatures upfront eliminates last-minute scrambling. If you are unsure how your current documents hold up, Kenny Realty's owner FAQ covers common lease and compliance questions.
Collect and Verify Banking Details before Move-Out
An electronic refund is only as good as the account information behind it. Build a step into your move-out checklist that confirms each tenant's preferred digital refund method and current account details. For roommate households, confirm whether a written split-payment agreement exists.
Tighten Your Accounting Workflow
Digital refunds should leave a clean paper trail: the transfer record, the itemized statement, and proof of delivery. Professional-grade financial reporting makes this straightforward and provides defensible documentation if a dispute ever ends up in small claims court. The California Courts self-help center is a useful reference for how deposit disputes are typically handled.
Consider Professional Management
Legislative changes like AB 414, AB 628, and the state's evolving rent control rules keep stacking up. A professional manager tracks these changes so you do not have to, and Kenny Realty backs its service with clear pricing and industry-leading guarantees.
Frequently Asked Questions
Does AB 414 apply if my tenant always paid rent by paper check?
The electronic refund default is triggered when the tenant pays rent or the deposit digitally. If every payment throughout the tenancy was made by paper check or cash, the traditional refund method still works. That said, most Bay Area tenancies today involve at least some digital payment, so assume the law applies unless your records clearly show otherwise.
Can I still mail a deposit refund check after January 1, 2026?
Yes, but only if both you and the tenant have agreed to that method in writing. Without written agreement, a mailed check to a tenant who paid digitally puts you out of compliance, even if the amount and timing are correct.
Did AB 414 change how much I can deduct from a security deposit?
No. Deduction rules under Civil Code 1950.5 are unchanged: you may still deduct for unpaid rent, damage beyond normal wear and tear, and cleaning needed to restore the unit to its move-in condition. AB 414 only changes the delivery method for refunds and itemized statements.
Turn Compliance into a Competitive Edge
AB 414 is ultimately a modernization, and landlords who adapt early will find move-outs faster, cleaner, and better documented than ever. Electronic refunds mean no lost checks, instant proof of payment, and an easier path to meeting the 21-day deadline, while written consent clauses added today prevent disputes tomorrow.
