In California, rent is due on the date written into your lease, and for nearly every tenant that date is the first of the month. If your lease happens to be silent on when rent is due, state law sets a surprising default: rent becomes payable at the end of the rental period rather than the beginning.1California Legislative Information. California Code CIV Division 3, Part 4, Title 5, Chapter 2, Section 1947 That default almost never governs in practice, because written leases spell out a due date and the contract controls.
Knowing the exact due date matters because it starts the clock on everything that follows a missed payment: late fees, the formal written notice your landlord must serve, and ultimately a court case.
What the Statute Actually Says
Civil Code Section 1947 is short. When no contract or custom states otherwise, rent is payable at the “termination of the holding.” For a month-to-month tenancy that would mean the last day of the month; for a one-year lease it would theoretically mean the end of the year.1California Legislative Information. California Code CIV Division 3, Part 4, Title 5, Chapter 2, Section 1947 You will rarely encounter this default in the real world. Standard written leases override it with a specific due date, and that date is binding. If your lease says the first, rent is due on the first. If it says the fifteenth, rent is due on the fifteenth.
Is There a Grace Period?
California does not require a grace period. Rent is legally late the day after it is due. If your lease does not include a grace period, you have no right to extra time, and the landlord can begin acting on the missed payment immediately.
Many leases voluntarily include a cushion of three to five days before late fees kick in, but that is a contract term rather than a legal entitlement. Read your lease. If it is silent on grace periods, assume you don’t have one.
What Late Fees Can a Landlord Charge?
California sets no statutory dollar cap or percentage ceiling on late fees, but courts treat them as a form of liquidated damages and apply a strict reasonableness test. A late fee is only enforceable if it reflects a genuine pre-estimate of the landlord’s actual losses from a late payment. In Orozco v. Casimiro, a California appellate court voided a late fee provision under Civil Code Section 1671, holding that residential late charges are presumed invalid unless the landlord can show that actual damages from late payment would be impractical to calculate and that the fee reasonably approximates them.
In practice, courts have generally upheld fees around 5 percent of monthly rent. Fees between 5 and 8 percent face heavier scrutiny and require documentation of actual costs. Anything above 8 to 10 percent is routinely struck down as a penalty. Daily compounding late charges almost never survive. If you believe your late fee is excessive, you can challenge it, and the landlord carries the burden of proving the amount is reasonable.
The Three-Day Notice to Pay or Quit
If rent goes unpaid, the landlord’s first required step is serving a written three-day notice to pay rent or quit. The requirements under Code of Civil Procedure Section 1161 are specific. The notice must state the exact amount of unpaid rent, name the person who can accept payment and provide a phone number, and include either a physical address where you can pay in person (with the days and hours that person is available) or a bank account number for deposit.2California Legislative Information. California Code of Civil Procedure Section 1161
The three days exclude Saturdays, Sundays, and judicial holidays, so you often get five or more calendar days in practice.2California Legislative Information. California Code of Civil Procedure Section 1161
One detail trips landlords up more than any other: the notice cannot demand more than the actual rent owed. If late fees, utility charges, or other sums are tacked on, the notice is defective and can be defeated in court. If you receive a three-day notice, check the dollar figure first.
How the Notice Must Be Delivered
The person serving the notice must be at least 18. California allows three delivery methods:
- Personal delivery, meaning the notice is handed directly to the tenant.
- Substituted service, where the notice is left with another adult at the tenant’s home or workplace and a copy is also mailed.
- Post and mail, where the notice is posted on the tenant’s door and a copy is mailed.
Whoever serves the notice must document exactly how and when it was served.3Judicial Branch of California. Deliver the Notice (Give Notice) Improper service is a defense you can raise if the landlord sues.
What Happens If You Still Don’t Pay
If you neither pay the full amount nor move out within the three-day window, the landlord can file an unlawful detainer lawsuit. The landlord cannot remove you directly. Only after a judge rules in the landlord’s favor can the sheriff enforce a lockout.4Judicial Branch of California. The Eviction Process for Landlords
Unlawful detainer cases move faster than ordinary civil lawsuits, but still take time. From filing to final lockout, the process generally runs 30 to 45 days or longer.4Judicial Branch of California. The Eviction Process for Landlords Once you are served with the lawsuit, you typically have five days to file a response. If you don’t respond, the landlord can request a default judgment. If you do respond, the court schedules a trial, usually about a month after the paperwork is filed.5Judicial Branch of California. What to Expect at an Eviction Trial
Tenants have real defenses in these cases. A defective three-day notice (wrong amount, missing information, improper service) can defeat the case. A landlord retaliating against you for exercising a legal right is another defense. So is the landlord’s failure to maintain livable conditions. These defenses don’t erase the rent owed, but they can defeat the eviction itself.
What Your Landlord Cannot Do While You’re Behind
No matter how far behind you are, your landlord cannot take matters into their own hands. Civil Code Section 789.3 makes it illegal for a landlord to change your locks, shut off your utilities, remove doors or windows, or haul away your belongings to pressure you into leaving.6California Legislative Information. California Code CIV Division 2, Part 2, Title 2, Chapter 2, Section 789.3 These self-help tactics are illegal regardless of how much rent is owed or how long nonpayment has continued.
If a landlord tries any of them, you can sue for actual damages plus a statutory penalty. The only lawful route to remove a tenant in California is the court-supervised unlawful detainer process.
How You’re Allowed to Pay the Rent
California also restricts how landlords can collect. Under Civil Code Section 1947.3, a landlord must accept at least one payment method that is neither cash nor electronic funds transfer. A landlord cannot force you to pay exclusively through an online portal or app, and cannot charge a fee for paying by check.7California Legislative Information. California Code CIV Section 1947.3
There is one narrow exception. If you previously bounced a check or issued a stop-payment order, the landlord can demand cash-only payment for up to three months. They must give you written notice explaining the switch and attach a copy of the dishonored check.7California Legislative Information. California Code CIV Section 1947.3 After that three-month window, non-cash payment must again be accepted.
The law also requires landlords to accept rent from a third party on your behalf, such as a relative or a social service agency, as long as the third party signs a statement confirming they are not a tenant and that paying does not create a tenancy for them.7California Legislative Information. California Code CIV Section 1947.3 This matters when you are scrambling to cover rent before the three-day notice period runs out.
