California Late Fee Law

Grace period: No grace period required by state law

Fee cap: $75.00 — 5% of the monthly rent (guideline, not a statutory cap)

Daily fees: Not typical

Statute: Cal. Civ. Code § 1671 (liquidated damages)

No statutory cap or required grace period, but the fee must be a reasonable estimate of actual damages (liquidated-damages rule) — inflated fees are unenforceable. Courts commonly accept ~5% or a modest flat fee. Some rent-controlled cities impose local limits.

Laws change quietly. Colorado rewrote its late-fee rules in 2021, Connecticut in 2023. Get an email when California changes its rules — and what to update in your lease.
