Your Late Fee Is Probably Void

Ask a California landlord what their late fee is and you'll get an answer immediately — five percent, or a flat amount, or something more after the fifth. Ask where the number came from and the answer is almost always that it was in the lease template.

Here's what almost nobody knows. There is no statute authorizing late fees in California. There's no permitted percentage and no statutory maximum. What there is instead is Civil Code §1671(d), and it starts from the opposite end than you'd expect.

The default is void

Under §1671(d), a liquidated damages provision in a consumer contract — which a residential lease is — is void, except where the parties agree on an amount that is presumed to be the damage sustained, and only when it would have been impracticable or extremely difficult to fix the actual damage.

Read the order of operations. Commercial contracts under §1671(b) presume such clauses valid and put the burden on the party challenging them. Residential leases work the reverse way. The clause starts out void, and the landlord carries the burden of establishing why it isn't.

In 2004, in Orozco v. Casimiro, a California appellate division identified a residential late fee as liquidated damages within the meaning of §1671 and struck it down because the landlord hadn't shown it was a reasonable estimate of anything. A later decision reinforced the point: the fee has to reflect a real estimate of loss, not punish the tenant or generate revenue.

So the sentence in your lease that says a late fee "shall be charged" — standing alone — is the exact structure the statute presumes void. Reciting an amount is not the same as justifying one.

What a defensible late fee looks like

Two things have to be true, and both have to be in the lease.

The lease has to say the actual damages are impracticable or extremely difficult to fix, and that the amount is a reasonable endeavor to estimate them. If your lease doesn't contain that recital, you haven't even attempted the test the statute sets.

The amount has to be tied to something real. Your actual cost of a late payment is administrative — the time spent following up, the bookkeeping, the notice if it goes that far. On a single unit that is not a large number. I'm deliberately not naming a percentage here, because there isn't one in the statute and every figure in circulation is somebody's guess at where a court would draw the line. Work from your actual cost and be able to explain it.

The honest read: a modest fee, properly recited, tied to administrative cost, applied consistently, has a reasonable chance of holding up. A number you picked because it sounded motivating does not.

There is no grace period in California law

This surprises people in both directions.

No statute gives a tenant a grace period. Rent is late the day after it's due. If your lease says the fifth, that's a term you granted — not a right they have.

But the flip side bites harder: if your lease says the fifth, you can't charge on the second. And if you've spent a year accepting rent on the eighth without comment, you've built a course of conduct that a tenant will point to when you suddenly start enforcing.

Pick a date, put it in the lease, and apply it the same way every month.

You cannot require electronic payment only

This one catches new landlords constantly, because the obvious modern setup is the unlawful one.

Civil Code §1947.3 requires you to allow at least one form of rent payment that is neither cash nor electronic funds transfer. In practice that means a check or money order. You may offer Zelle, Venmo, or a portal — you may not require it as the only option.

You also can't demand cash-only payment, with a narrow exception following a bounced check. And returned check charges are capped by Civil Code §1719 — twenty-five dollars for the first, thirty-five for subsequent ones. Not whatever your bank charged you plus an inconvenience premium.

The Backyard Landlord

Rent that's four days late is an accounting item when the tenant lives across town. It's something else entirely when their car is in your driveway and you can see the lights on.

Three things go wrong in backyard tenancies, and all of them are about proximity rather than law.

You'll take payment informally. Cash in an envelope through the kitchen door, a Venmo with no memo line, a partial payment with the rest promised Friday. Then a dispute arises and neither of you can reconstruct what was paid when. Require one method with a record — check, money order, or a transfer that generates a receipt — and log every payment the day it arrives. If someone hands you cash, write a receipt and keep a copy. Every time, including the months when everything is fine.

You'll stop enforcing, then start again. This is the one I'd flag hardest. Because you see them daily, and because confrontation with someone thirty feet away is genuinely unpleasant, you'll let it slide in month three and month five and month nine. Then in month eleven something else sours and you decide to enforce the fee. A tenant who has paid late eleven times without consequence has a straightforward argument that the term was waived, and the sudden enforcement looks like retaliation for whatever the real dispute is.

The alternative isn't being harsh. It's picking a fee small enough that you're willing to charge it every single time, and then charging it every single time. Consistency is worth more than the amount.

And you'll be told in person. They'll catch you at the mailbox and explain why this month is different. In a normal tenancy that conversation happens by email and leaves a record. Here it happens in your driveway and leaves nothing.

If you grant an exception — and sometimes you should — put it in writing afterward. One line, by text or email: rent for March due the 12th this month, late fee waived, regular terms resume in April. It takes fifteen seconds, it protects the term you're temporarily setting aside, and it keeps a kindness from turning into a pattern you can't unwind.
