Your $35K Lease Now Carries a $35K Deposit. What Replaces the Rest

A Woodside owner asked me in June why her new lease showed a $38,000 deposit when the last tenant, four years ago, had put down more than three times that. The house is fully furnished. There's a Steinway in the living room.

The answer is AB 12, and if you haven't leased an estate since mid-2024 it's probably the single largest change to how you're protected, and nobody sent you a letter about it.

What Changed

Before July 1, 2024, California let a landlord take two months' rent as a security deposit on an unfurnished unit and three months on a furnished one. High-end Peninsula leases are almost always furnished, so three months was the working standard on this kind of property.

AB 12 collapsed that. Civil Code 1950.5 now says a landlord "shall not demand or receive security, however denominated, in an amount or value in excess of an amount equal to one month's rent, in addition to any rent for the first month paid on or before initial occupancy."

The furnished distinction is gone entirely. A furnished estate and a bare one-bedroom are treated identically. On a $35,000-a-month house, protection went from a possible $105,000 to $35,000.

That is a real problem on this kind of property and I don't want to soften it. A single refinishing job on wide-plank white oak after a dog, or one water event on a rug that belongs in the house rather than to the tenant, can run past a month's rent by itself.

Two Words That Do a Lot of Work

Read the cap again: "security, however denominated."

That phrase is why the workarounds owners suggest to me mostly don't work. The statute defines security broadly enough to swallow almost any up-front money that isn't the first month's rent. A pet deposit is security. A cleaning fee is security. Last month's rent collected at signing is security, and it counts against the same one month.

I've had two owners this year propose taking "a deposit plus a separate furnishings bond." That's still security, still capped, and now it's also mislabeled in a way that wouldn't help you in front of a judge.

The Exception Most Estate Owners Qualify For

Read this part closely. A surprising number of my clients qualify and none of them knew it.

Civil Code 1950.5 keeps a two-month cap available to a landlord who is a natural person, or a limited liability company in which all members are natural persons, and who owns no more than two residential rental properties collectively including no more than four dwelling units offered for rent.

Read that against a typical Peninsula owner. One estate in Atherton, held in an LLC whose members are the owner and their spouse, maybe a second rental property somewhere. That's two properties and one or two units. They qualify. They can take two months rather than one, which on the Woodside house above is $76,000 instead of $38,000.

The traps are specific and worth checking rather than assuming. If a trust or a corporate entity is a member of the LLC rather than an individual, you likely fall out. If you own three rental properties, you fall out, even if they're all small. And the exception does not apply to a servicemember tenant under any circumstances, which is worth flagging because officers stationed at Moffett do rent at this end of the market.

Have your attorney confirm your ownership structure against that language before you write a number on a lease. It's a five-minute question with a $38,000 answer.

The Provision Nobody Uses

This is the one I'd point most owners to, and I almost never see it in Peninsula leases.

Civil Code 1950.5 subdivision (c)(2) says the cap "does not prohibit an advance payment of not less than six months' rent if the term of the lease is six months or longer."

Six months of rent, paid up front, on a lease of six months or more. On a $35,000-a-month house that's $210,000 sitting in your account before the tenant moves in. It isn't a deposit and doesn't behave like one, so don't think of it as damage protection. What it does is remove nonpayment from your list of concerns for the covered period, which on a luxury tenancy is the loss that hurts, because unwinding a defaulted lease on a $35K house takes months you can't rent.

Two honest caveats. Some tenants won't do it, and an executive relocating on a corporate package often can't, because their employer pays monthly. And it's an all-or-nothing provision as written: not less than six months. You can't take three and call it advance rent.

Where it works well is the tenant profile we see a lot on the Peninsula right now: liquidity-rich, income-lumpy, recently through an exit. For that person, prepaying a year is easier than producing a pay stub, and I've had it offered to me unprompted.

What Replaces the Rest

If your deposit protection got cut in half, it has to come from somewhere else. In practice it stops being a deposit question at all.

Screening does the most work. When your deposit was three months, screening could be adequate. At one month it has to be genuinely good, which on this kind of property means verified liquidity rather than a credit score, actual landlord references from the last two tenancies, and the entity check if a company or trust is signing. I've written up the deeper version of this for high-end tenancies but the summary is that the tenant is now the collateral.

Insurance requirements do the second most. Require renter's liability at a limit that matches the house, name yourself as additional insured, require proof at signing and again at each renewal, and don't accept a binder as proof. This is cheap for the tenant and it's the only part of the stack that scales with the value of what's in the house.

Then the lease itself. Specific riders on the specific things that can go wrong at your property, with named vendors and stated standards, matter more now than when a large deposit could absorb a surprise. That's the argument for the clauses I don't sign without, and for handling the Zone 0 obligations explicitly rather than leaving them to be argued about later.

The Move-Out Side Got Stricter Too

Worth knowing while you're in here. You have 21 calendar days after the tenant vacates to return what's left and provide an itemized statement. Miss it and you can forfeit the right to keep any of it, which on $38,000 is an expensive administrative error.

If the tenant paid you electronically, the statute now contemplates returning the deposit electronically to an account the tenant designates in writing. Get that designation at move-out rather than chasing a forwarding address for a family that's already in London.

On a furnished estate, the practical defense is a move-in condition report with date-stamped photographs of every room and every significant piece, signed by the tenant. With a month's cushion instead of three, an itemization you can prove is worth more than one you can merely assert.

Before You Sign the Next One

Ask your attorney whether your ownership structure clears the two-month exception. Most single-estate owners I work with do, and it's free money left on the table if you don't check.

Decide in advance whether you'll offer the six-month advance rent option, and price a small concession against it if you want it taken. A tenant who prepays half a year is a different risk than one who doesn't, and you can afford to acknowledge that in the rent.

Then stop thinking of the deposit as the protection. It hasn't been the main event since 2024. On a house like this the protection is who you let in, what they carry for insurance, and what your lease says about the things that break.

If you're leasing a Peninsula estate and want the deposit, insurance, and screening structure reviewed before you sign, schedule a confidential consultation. We manage properties across Atherton, Woodside, Portola Valley, Palo Alto, and Los Altos Hills.
