Q: Is there a cap on storage unit rent increases in California?

A: Feels like a bait and switch. THAT said, regardless of any CAP, it's HIGHLY likely that they must give you 30 day notice prior to raising the rent. One way to get them is to take your biz elsewhere and get the initial teaser rate...

A: Unlike residential housing, storage units in California are not subject to the same rent control laws that limit rent increases. The laws that cap rent increases (such as AB 1482, the Tenant Protection Act) specifically apply to residential dwellings, not commercial storage facilities. This means storage companies can legally increase their rates without the same restrictions that apply to apartment rentals.

Regarding written notice, most storage unit contracts require the facility to provide advance notice of rate increases, typically 30 days before the new rate takes effect. You should review your rental agreement carefully to see what it says about rate increases and required notifications. If your contract specifies that written notice must be provided and the company failed to do so, they may be in breach of contract.

Your best course of action would be to request a copy of your rental agreement and review the terms. Consider discussing the lack of proper notification with the facility manager or district supervisor. If you believe they've violated the terms of your agreement, you might contact the California Department of Consumer Affairs for guidance or consult with a legal advisor who handles consumer protection issues. You could also research other storage facilities in your area to compare rates and potentially find a more stable pricing option.
