Are you up to date on all the latest changes in security deposit law?
We don’t have to tell you that the Bay Area is one of the most regulated rental markets in the country. If you’re renting out property here, you likely already know that.
Over the last two years, significant changes have landed on the way that security deposits are collected and returned. The state has implemented new limits and the city is strict about how much interest those deposits are collecting for the tenants.
As local property managers in the Bay Area, we’re following the law carefully, and we’ve put together some information on how much landlords can collect, how deposits must be documented, and how they’re returned.
We are looking at compliance requirements that affect security deposit amounts, photographic evidence, electronic returns, and updated interest expectations. If you’re a landlord stuck in the days of collecting deposits according to the older “first, last, and security” model, this is not a minor adjustment for you. It’s more of a structural change.
Our Overview:

The Core Change: AB 12 Caps Deposits at One Month’s Rent
Effective July 1, 2024, AB 12 amended California Civil Code §1950.5 to limit most residential security deposits to one month’s rent, regardless of whether the unit is furnished or unfurnished. In practice, this change means that managing risk requires a different type of attention.
For most landlords, the maximum deposit will be the equivalent of one month’s rent. This new law applies to all residential leases signed on or after July 1, 2024. All forms of deposits are rolled into this one limit. You cannot charge a security deposit that’s equivalent to one month’s rent and then also charge a pet deposit for $400 more than that.
This represents a major shift from the prior law, which allowed up to two month’s rent if your property was unfurnished.
Another important change here is that collecting “last month’s rent” ahead of move-in is no longer an option. Some landlords historically charged last month’s rent separately, but under AB 12, any upfront payment beyond the first month’s rent is treated as part of the security deposit, and therefore subject to the one-month cap.
The Small Landlord Exception
Not every property owner is bound by the strict one-month limit. As with most California rental laws, there are exceptions. You may charge up to two months’ rent if you meet all of the following:
- You are a natural person and not a corporation (or qualifying LLC/trust)
- You own no more than two rental properties
- Those properties total no more than four units
Just because you can collect a higher security deposit does not mean that you should. In a competitive rental market like the Bay Area, even landlords who qualify for this exception should think strategically about what’s being asked. Remember that too-high deposits can deter qualified tenants.
Existing Leases vs. New Leases
What about your lease that was in place before this new limit went into effect? AB 12 is not retroactive.
- Deposits collected before July 1, 2024, can remain as-is
- New leases or renewals must comply with the new cap
This creates a dual system where legacy tenants may have higher deposits than new ones. We note this because it’s something to keep in mind for accounting and tenant relations.
What Landlords Can Still Deduct
AB 12 did not change the fundamental rules around allowable deductions. Under California law, landlords can still deduct for:
- Unpaid rent that’s due after a tenant moves out of the property
- Cleaning (to restore original condition)
- Damage beyond normal wear and tear
- Repair or replacement of landlord-owned property
However, newer legislation tightens how you justify those deductions, which brings us to the next major shift. There are new requirements in place for how and what you document.
Understanding the 2025–2026 Update: Mandatory Photographic Evidence
Starting in phases through 2025, California law now requires robust photo documentation tied to security deposits. As professional property managers, we’ve been putting these practices into place for years. But as an independent landlord, there may be changes you need to make in order to comply.
Key requirements include:
- Pre-move-in photos (starting July 1, 2025)
- Move-out photos immediately after vacancy
- Post-repair photos documenting work completed
These images must support any deductions you claim. Establishing the condition of your property before tenants take possession of it is now more essential than ever. You’ll have to use that documentation to justify the deductions you make from a security deposit. Without evidence, you’ll have a difficult time convincing the courts that you were justified in withholding that money.
Why does this matter?
Without photographic evidence, your ability to retain deposit funds becomes legally vulnerable. In disputes, the burden increasingly shifts to landlords to prove:
- The condition at move-in
- The damage at move-out
- The necessity and cost of repairs
This effectively transforms security deposit management into a documentation-driven process rather than a discretionary one. If you’re not set up to manage this proactively, make sure you work with a professional property manager in the Bay Area like us at Sharevest Property Management.
Electronic Return of Deposits (Emerging Requirement)
Let’s talk about some of the newer legislation that’s having an impact on security deposits in the Bay Area (including AB 414 and related updates). Of particular interest is the introduction of electronic return options for security deposits.
While traditional methods (checks) are still permitted, landlords must now be prepared to:
- Offer or accommodate electronic refund methods
- Manage secure transfer of tenant banking details
- Address fraud risks (for example, account change scams)
For property managers, this adds an operational layer to the work you do, particularly around compliance, record-keeping, and cybersecurity.
Providing Interest on Security Deposits (San Francisco Context)
While California state law does not mandate interest on deposits universally, San Francisco has its own requirements, and you’ll need to comply with those when you have rental properties inside of the city.
For deposits held over one year, the applicable interest rate for March 1, 2026 until February 28, 2027 is 4.2%.
This means landlords must:
- Track deposit holding periods
- Calculate accrued interest annually
- Return both principal and interest upon move-out
Failure to do so can expose landlords to penalties or tenant claims.
Operational Impact for Bay Area Landlords
How can you prepare for the new laws around security deposits and the new restrictions that may be coming later on? For starters, partner with a smart property management team (us). In addition, it will help to implement the following strategies.
- Reduced Upfront Risk Buffer
The one-month cap reduces your financial cushion against tenant damage, lease breaches, and any cleaning and turnover costs that you may have to absorb. This increases reliance on tenant screening, renters insurance requirements, and preventative maintenance.
- Increased Administrative Burden
New compliance tasks include detailed photo documentation workflows, secure electronic payment systems, and interest tracking and accounting.
- Higher Litigation Risk if Non-Compliant
Because these laws are highly tenant-protective, non-compliance can lead to deposit disputes, small claim actions, and statutory penalties.
Best Practices Moving Forward for Bay Area Rental Property Owners
To adapt effectively, landlords should consider the following actions.
- Standardize Documentation
Create a repeatable process for move-in inspections, photos that are timestamped, and repair documentation.
- Update Lease Agreements
Ensure your lease reflects deposit limits, electronic return options, and inspection procedures.
- Invest in Property Management Tools
Digital platforms can help track deposits and interest, inspection photos, and tenant communications.
- Reevaluate Screening Criteria
With less financial protection upfront, tenant quality becomes even more critical. In addition to new security deposit laws, screening laws have also become more intense.
Strategic Perspective: What This Means Long-Term
AB 12 and related laws signal a broader trend in California housing policy:
- Lower barriers to entry for renters
- Increased regulatory oversight of landlords
- Greater emphasis on transparency and fairness
For landlords, success will increasingly depend on process discipline rather than financial leverage.
Our FAQs
Q1: Can I still charge a pet deposit?
No. Pet deposits are considered part of the overall security deposit and must fit within the one-month cap.
Q2: Do I need to refund excess deposits from older leases?
No. AB 12 does not require refunds for deposits collected before July 1, 2024.
Q3: What happens if I don’t take photos?
You risk losing the ability to legally justify deductions, especially in disputes.
Q4: How quickly must I return the deposit?
California law generally requires return within 21 days of move-out.
Q5: Does the one-month cap apply to all landlords?
No. Some small landlords qualify for a two-month exception, but strict criteria apply.
For Bay Area landlords, the takeaway should be clear: security deposits are no longer just a financial safeguard for owners. They are a tightly regulated system requiring precision, transparency, and consistency.
