30 days rent-increase notice.
For increases of 10% or less, the landlord must give 30 days' written notice; for larger increases, 90 days. Under AB 1482, annual increases on covered units are capped at 5% plus local CPI, never more than 10%.
What this means for you: Most apartments built more than 15 years ago are covered by the statewide cap. Single-family homes owned by individuals may be exempt but must disclose that in writing.
Your next step: Check whether your unit is covered by AB 1482 and verify the increase math. If it exceeds the cap, raise it in writing with the landlord.
