Summary

California sets no fixed dollar or percentage cap on rent late fees, but a late fee in a residential lease is treated as liquidated damages. Under Civil Code § 1671, such a fee is valid only if it reasonably estimates the landlord's actual loss from late payment; arbitrary penalty fees are unenforceable.

In the cases described in subdivision (c), a provision in a contract liquidating damages for the breach of the contract is void except that the parties to such a contract may agree therein upon an amount which shall be presumed to be the amount of damage sustained by a breach thereof, when, from the nature of the case, it would be impracticable or extremely difficult to fix the actual damage.

Full Breakdown

California has no statute setting a maximum late fee. Instead, a late fee is a liquidated-damages clause governed by Civil Code § 1671(d), which makes such provisions in residential leases "void except that the parties... may agree... upon an amount which shall be presumed to be the amount of damage sustained by a breach thereof, when, from the nature of the case, it would be impracticable or extremely difficult to fix the actual damage." California courts (e.g., Orozco v. Casimiro) have voided late fees that function as penalties rather than genuine estimates of the landlord's costs, such as administrative expense and lost use of funds. A fee unrelated to actual damages is unenforceable even if the lease recites it.

Violations & Penalties

An unenforceable penalty late fee cannot be collected, and amounts already paid may be recoverable by the tenant. Relying on an unlawful penalty fee in an eviction can defeat the unlawful detainer if it inflates the rent demanded.

Frequently Asked Questions

Is there a maximum late fee for rent in California?
No. California has no fixed statutory cap. A late fee is valid only if it is a reasonable pre-estimate of the landlord's actual damages from late payment under Civil Code § 1671(d); an arbitrary penalty amount is unenforceable.
Can a California landlord charge any late fee they want?
No. The fee must reflect the landlord's genuine costs of late payment. Courts have struck down flat penalty fees that bear no relationship to actual damages, treating them as void liquidated-damages clauses.
What happens if a late fee is found to be a penalty?
It is void and cannot be collected, and a tenant may be entitled to recover amounts already paid. It also cannot lawfully inflate the rent demanded in an unlawful detainer action.
