The Statutory Rule: One Month, No Exceptions for Furnished Units
Furnished coastal rentals saw deposit caps drop by 67%, eliminating the three-month allowance that previously cushioned landlord risk.

Cal. Civ. Code § 1950.5(c), as amended by AB 12, states plainly: 'The amount of the security deposit shall not exceed an amount equal to one month's rent.' The statute took effect July 1, 2024, and applies to every new tenancy commenced on or after that date, plus any deposit increase attempted on an existing tenancy. The prior allowance — two months' rent for unfurnished units, three months for furnished — is gone. Furnished status no longer justifies a higher deposit.

For coastal owners, this change hits hardest on furnished luxury rentals. A $14,500/month oceanfront single-family home in Dana Point that previously collected a $43,500 deposit (three months) now caps at $14,500. A $9,200/month furnished Laguna Beach rental that took $27,600 up front is limited to $9,200 going forward. The delta represents real cash-flow exposure: owners who relied on multi-month deposits to self-insure against tenant damage or lease-break now carry that risk on their own balance sheet or push it to a landlord-policy rider.
The statute makes no distinction between short-term-to-long-term conversions and purpose-built long-term rentals. An STR owner in Newport Beach who pivots to a 31+ day lease to escape TOT or local permit requirements immediately falls under § 1950.5(c). The furnished-unit carve-out that once provided a compliance cushion is legislatively extinct.
The Small-Landlord Exemption: Natural Persons, Two Properties, Four Units
All three thresholds must be met simultaneously to qualify for the two-month deposit allowance; failing any single test triggers the one-month cap.

| Category | Maximum threshold |
|---|---|
| Natural person (not entity) | 1 |
| ≤2 properties owned | 2 |
| ≤4 total units | 4 |
AB 12 preserved a narrow exemption codified in § 1950.5(c)(1): 'This subdivision does not apply to a natural person who owns no more than two residential real properties that contain no more than four dwelling units in total.' Landlords who meet all three tests may still collect up to two months' rent as a security deposit. The tests are conjunctive — fail any one and the exemption collapses.
Natural Person Test
The exemption is available only to human beings. LLCs, corporations, partnerships, and trusts are categorically excluded, even if the entity owns a single property and is managed by a single individual. A solo investor who holds title in Smith Family Trust or Coastal Rentals LLC does not qualify. The statute offers no safe harbor for single-member LLCs, no exception for revocable living trusts, no carve-out for family partnerships. Entity ownership — regardless of size, structure, or beneficial-ownership simplicity — triggers the one-month cap.
Two-Property Test
The natural person may own no more than two residential real properties. The count is by property, not by unit. A duplex on one parcel counts as one property; two single-family homes on separate parcels count as two properties. An investor who owns a triplex in Huntington Beach and a single-family rental in Dana Point holds two properties and remains eligible. Add a third property — even a single condo — and the exemption is lost across the entire portfolio.
Four-Unit Test
The two properties may contain no more than four dwelling units in total. A duplex plus a duplex (four units across two properties) qualifies. A triplex plus a single-family home (four units) qualifies. A fourplex alone (one property, four units) qualifies. A duplex plus a triplex (five units across two properties) does not. The cap is aggregate, not per-property.
The small-landlord exemption is a scalpel, not a blanket. Coastal owners who cleared the two-property, four-unit bar in 2024 must re-test annually — acquiring a third property or converting a garage to an ADU can silently disqualify the portfolio and expose every lease renewal to treble-damage liability if deposits are not corrected within a reasonable cure window.
Treatment of Pre-July 1, 2024 Deposits
AB 12 does not require landlords to refund deposits collected before July 1, 2024 down to the new one-month limit. A lease signed in May 2024 with a $18,400 deposit on a $9,200/month unfurnished rental (two months under prior law) may stand as-is through the lease term. The tenant has no statutory right to demand a mid-lease refund of the excess $9,200.
However, the deposit cannot be increased upon renewal or lease modification. If the landlord raises rent to $9,600/month in 2026, the deposit must be reduced to $9,600 — not increased to match two months of the new rent. The statute effectively grandfathers legacy deposits at their nominal dollar amount but prohibits any upward adjustment that would exceed one month of the current rent.
Our coastal California team advises a proactive reconciliation at every renewal: calculate one month of the new rent, compare to the existing deposit on file, and refund any excess within the 21-day window following lease execution. This approach avoids the ambiguity of whether a rent increase coupled with a deposit hold constitutes an impermissible increase under § 1950.5(c).
The 21-Day Return Rule and AB 2801 Documentation
Cal. Civ. Code § 1950.5(g) requires landlords to return the deposit — or provide an itemized statement of deductions — within 21 calendar days after the tenant vacates. The timeline is strict: day one is the day the tenant surrenders possession and returns keys; day 21 is the postmark deadline. Miss it and the landlord forfeits the right to retain any portion of the deposit for damages, even if the damages are legitimate and well-documented.
AB 2801, effective for tenancies commencing on or after July 1, 2025, overlays a new documentation standard. Landlords must provide photo or video evidence of any damage claimed in the itemized statement, plus receipts or invoices for repair costs. The statute does not mandate move-in photos, but the practical necessity is clear: without a timestamped move-in baseline, the landlord cannot prove that a stained carpet or chipped countertop was tenant-caused rather than pre-existing wear.
The 21-day clock does not pause for contractor scheduling delays or invoice lag. Our standard operating procedure: complete the move-out walk within 48 hours of tenant departure, photograph every surface and fixture, obtain repair bids within one week, and issue the itemized statement by day 14. The seven-day buffer accounts for contractor no-shows, parts delays, and the reality that coastal trade labor runs on island time.
AB 2216 Pet-Deposit Cap
AB 2216, effective January 1, 2025, prohibits landlords from demanding a pet deposit that exceeds the equivalent of one month's rent when combined with the security deposit. The statute does not create a separate pet-deposit allowance on top of the AB 12 one-month cap; instead, it clarifies that the total of security deposit plus pet deposit cannot exceed one month's rent.
Worked example: $9,200/month Laguna Beach rental, tenant with one dog. Maximum combined deposit under AB 12 and AB 2216: $9,200. The landlord may structure this as $7,000 security + $2,200 pet, or $9,200 security + $0 pet, or any split that sums to $9,200. The landlord may not collect $9,200 security plus $1,500 pet for a total of $10,700.
AB 2216 also prohibits non-refundable pet fees in the residential context. Every dollar collected as a pet-related charge must be refundable under the same 21-day, itemized-deduction framework that governs the security deposit. Landlords who previously charged a $500 non-refundable pet fee must either eliminate the fee or reclassify it as part of the refundable deposit and count it against the one-month cap.
Interaction with AB 1482 Rent-Cap Rules
AB 1482 (Cal. Civ. Code § 1947.12) caps annual rent increases at 5% plus CPI, not to exceed 10%, for most residential tenancies in California. The rent cap and the deposit cap operate independently but intersect at lease renewal. When a landlord raises rent to the maximum allowable increase, the security deposit may be adjusted upward to match one month of the new rent — but only if the existing deposit is below that threshold.
Example: $8,000/month rent in January 2025, $8,000 deposit on file. CPI runs 3.2%; maximum allowable increase is 8.2%, bringing rent to $8,656 in January 2026. The landlord may request an additional $656 deposit to bring the total to $8,656 (one month of new rent). The tenant may pay the increase in a lump sum or amortize it across the first three months of the renewal term, per our standard lease addendum.
However, if the tenant's existing deposit already equals or exceeds one month of the new rent, no increase is permitted. A tenant paying $8,000/month with a grandfathered $16,000 deposit (two months under pre-AB 12 law) sees rent rise to $8,656 but the deposit must be reduced to $8,656 and the $7,344 excess refunded within 21 days of lease execution.
Short-Term-to-Long-Term Conversion Exposure
Coastal California's short-term rental market has contracted under municipal permit caps, TOT enforcement, and Coastal Commission scrutiny. Owners in Newport Beach, Laguna Beach, Dana Point, Santa Monica, Malibu, and Coronado who convert STR inventory to long-term rentals (31+ day leases) immediately trigger AB 12 compliance. The furnished-unit allowance that once justified a three-month deposit is gone; the new tenant pays one month, and the owner absorbs the risk delta.
The exposure is acute for oceanfront and harbor-view properties where prior STR operations collected $5,000–$15,000 damage deposits per booking. A Dana Point oceanfront home renting at $14,500/month long-term previously collected $43,500 as a furnished-unit deposit (three months). Post-AB 12, the cap is $14,500. The $29,000 shortfall cannot be offset by requiring the tenant to carry renters insurance with a liability rider — the statute sets a hard ceiling on what the landlord may collect and hold.
Our coastal California team has guided STR-to-LTR conversions since July 2024. The playbook: price rent to reflect the higher risk profile (we target a 15–20 basis-point yield premium over comparable unfurnished inventory), require tenants to carry $300,000 liability coverage naming the owner as additional insured, and deploy quarterly interior inspections rather than the annual standard. The deposit cap is non-negotiable; the lease terms and underwriting criteria are not.
Worked Examples: Dana Point and Laguna Beach
Dana Point Oceanfront SFR
- Monthly rent: $14,500
- Property type: Single-family, furnished, four bedrooms, ocean view
- Owner structure: Individual (natural person), owns one other triplex in San Clemente (four total units across two properties)
- Small-landlord exemption: Qualifies — natural person, two properties, four units total
- Maximum deposit: $29,000 (two months' rent under exemption)
- Lease commenced: September 2025
The owner meets all three exemption tests and may collect up to two months' rent. However, the tenant has a service dog. AB 2216 prohibits a separate pet deposit that would push the combined total above $14,500 unless the small-landlord exemption's two-month allowance also applies to the pet-deposit cap. The statute is silent on this interaction; our reading is that the exemption governs the security deposit under § 1950.5(c)(1) but does not override AB 2216's separate cap on pet-related charges. Conservative compliance: $29,000 total, structured as $27,000 security + $2,000 refundable pet deposit.
Laguna Beach Furnished Rental
- Monthly rent: $9,200
- Property type: Two-bedroom cottage, furnished, hillside location, partial ocean view
- Owner structure: Laguna Holdings LLC (single-member LLC, one property)
- Small-landlord exemption: Does not qualify — entity ownership disqualifies regardless of property count
- Maximum deposit: $9,200 (one month's rent, no exemption)
- Lease commenced: March 2025
The LLC structure forfeits the exemption. The owner previously collected $27,600 (three months under the furnished-unit rule). New tenancies are capped at $9,200. The owner cannot collect a separate pet deposit; AB 2216 folds pet charges into the one-month total. If the tenant has two cats, the landlord may allocate the $9,200 as $7,500 security + $1,700 pet, but the sum cannot exceed $9,200.
City-by-City Coastal Compliance Table
| City | State Cap Applies | Local Ordinance Overlay | Interest on Deposits Required |
|---|---|---|---|
| Newport Beach | Yes | None | No |
| Huntington Beach | Yes | None | No |
| Laguna Beach | Yes | None | No |
| Dana Point | Yes | None | No |
| Santa Monica | Yes | Rent Control Ordinance (SMMC Ch. 4.56) | Yes — annual interest at rate set by Rent Control Board |

| Encinitas | Yes | None | No |
| Solana Beach | Yes | None | No |
| Del Mar | Yes | None | No |
| La Jolla (SD) | Yes | None | No |
| Coronado | Yes | None | No |
Santa Monica and Venice (Los Angeles) impose interest-on-deposits requirements under local rent-control ordinances. The interest rate is set annually by the respective rent-control board and must be paid to the tenant at lease termination or annually, depending on the ordinance. Failure to pay accrued interest does not void the deposit, but the tenant may offset the unpaid interest against the final month's rent or recover it as a separate claim in small-claims court.
No other coastal city in our service area has enacted a deposit cap more restrictive than the state standard or added documentation requirements beyond AB 2801. Owners operating in Santa Monica and Venice must track the annual interest rate, calculate accrual, and include the interest payment in the 21-day deposit-return accounting.
Failure Modes and Treble-Damage Exposure
Cal. Civ. Code § 1950.5(l) authorizes treble damages when a landlord 'acts in bad faith in retaining all or a portion of a security deposit.' Bad faith is not defined by statute, but California courts have held that knowing retention of an excess deposit, failure to provide an itemized statement within 21 days, or deducting for normal wear and tear can each support a bad-faith finding. The tenant recovers the wrongfully withheld amount plus twice that sum as statutory damages, plus attorney fees if the lease or statute provides for fee-shifting.
Collecting More Than One Month After July 1, 2024
A landlord who collects a $18,400 deposit on a $9,200/month lease signed in August 2024 (absent small-landlord exemption qualification) has violated § 1950.5(c). The tenant may demand return of the $9,200 excess at any point during the tenancy. If the landlord refuses, the tenant's recovery is $9,200 (the excess) plus $18,400 (treble damages) plus attorney fees — a $27,600 judgment on a $9,200 mistake.
Failing to Itemize Deductions Within 21 Days
A landlord who misses the 21-day deadline forfeits the right to retain any portion of the deposit, even for legitimate damages. If the tenant sues, the court may award the full deposit plus treble damages if the landlord's delay is found to be in bad faith (e.g., the landlord ignored the tenant's forwarding address, made no effort to complete repairs, or simply forgot). A $9,200 deposit becomes a $27,600 liability.
Misclassifying Last Month's Rent as a Deposit
Some landlords collect 'first month, last month, and security deposit' at lease inception. AB 12 does not prohibit collecting last month's rent in advance, but the payment must be clearly labeled and applied. If the landlord calls it a deposit, commingles it with the security deposit, and later tries to re-characterize it as prepaid rent to avoid the one-month cap, the tenant can argue bad-faith misclassification. The safer structure: collect one month's rent (first month) plus one month's deposit, and require last month's rent to be paid 30 days before lease expiration.
LLC Claiming Small-Landlord Exemption
An LLC that collects two months' rent as a deposit, citing the small-landlord exemption, has misapplied the statute. The exemption is available only to natural persons; entity ownership disqualifies. The tenant may demand return of the excess month, and if the landlord refuses, treble damages attach. The landlord's good-faith belief that a single-member LLC qualifies is not a defense — the statute's text is unambiguous.
Charging a Non-Refundable Cleaning Fee
AB 12 and AB 2216 together prohibit non-refundable fees in the residential rental context. A landlord who collects a $500 'non-refundable cleaning fee' at move-in has violated § 1950.5. The fee must be refundable, must count against the one-month deposit cap, and must be returned (less itemized cleaning costs) within 21 days of move-out. Calling it a fee rather than a deposit does not change the legal character.
2026 Compliance Checklist
- Confirm owner structure: natural person or entity? If entity, one-month cap applies regardless of portfolio size.
- If natural person, count properties and units: ≤2 properties, ≤4 units total? If yes, two-month exemption available; if no, one-month cap applies.
- Review all active leases: any deposits collected before July 1, 2024 that exceed one month of current rent? If yes, plan refund at next renewal.
- Audit lease templates: remove any reference to two-month or three-month deposits; remove non-refundable pet fees; cap combined security + pet deposit at one month (or two months if exemption applies).
- Implement AB 2801 photo protocol: timestamped move-in photos of every room, fixture, and surface; store in tenant file; repeat at move-out within 48 hours.
- Calendar 21-day return deadline for every move-out; build seven-day buffer into internal workflow.
- Santa Monica and Venice properties: confirm current interest rate, calculate accrual, include in deposit-return accounting.
- Train leasing staff: no verbal promises of 'we'll work with you on the deposit' — the cap is statutory and non-negotiable.
- Review landlord insurance policy: confirm coverage for tenant damage exceeds one month's rent; consider increasing liability limits on high-value furnished inventory.
- Document small-landlord exemption eligibility annually: if owner acquires a third property or adds an ADU, exemption is lost and all deposits must be corrected within a reasonable cure period.
Frequently Asked Questions
Can I collect a higher deposit if the tenant has poor credit?
No. Cal. Civ. Code § 1950.5(c) sets a hard cap at one month's rent (or two months if the small-landlord exemption applies) regardless of the tenant's credit score, rental history, or risk profile. The landlord may deny the application or require a co-signer, but cannot exceed the statutory deposit limit.
What happens to my existing two-month deposits on leases signed before July 1, 2024?
Deposits collected before the effective date do not have to be refunded down to one month, but cannot be increased. If you raise rent at renewal, the deposit must be reduced to match one month of the new rent if the existing deposit exceeds that amount. The excess must be refunded within 21 days of the renewal lease execution.
Does the small-landlord exemption apply if I own two properties through separate LLCs?
No. The exemption requires ownership by a natural person — a human being. LLCs, corporations, partnerships, and trusts are categorically excluded, even if the entity owns only one property and is wholly owned by a single individual. If title is held in an LLC, the one-month cap applies.
Can I charge a non-refundable pet fee in addition to the security deposit?
No. AB 2216 prohibits non-refundable pet fees in residential rentals. Every dollar collected as a pet-related charge must be refundable under the same 21-day itemized-deduction framework that governs the security deposit, and the combined total of security deposit plus pet deposit cannot exceed one month's rent (or two months if the small-landlord exemption applies).
What is the penalty for collecting more than one month's rent as a deposit after July 1, 2024?
The tenant may demand return of the excess at any time. If the landlord refuses, the tenant can sue for the excess amount plus treble damages under Cal. Civ. Code § 1950.5(l) if the court finds the landlord acted in bad faith. A $9,200 excess deposit can become a $27,600 judgment plus attorney fees. The safer course is to refund the excess immediately upon discovery and document the correction in writing.
