You’re a good tenant. You pay your rent on time and respect the rules. So when a landlord suddenly tries to shift the goalposts with new rules, any resulting frustration you have may be completely justified. These changes might feel unreasonable, especially when you have already committed to a specific set of terms in your lease. Is it legal for landlords to make these changes?
What type of lease do you have?
The ability to change terms depends largely on the duration of your agreement.
If you have a fixed-term lease (like a one-year lease), your landlord generally can’t change major lease terms until the lease ends. Exceptions exist if the lease itself allows a mid-term change or you agree in writing to a lease amendment.
If you have month-to-month rental agreements, landlords usually have more flexibility with their changes. However, they must give proper notice and follow California rules.
When they can modify lease terms
Landlords have more flexibility with month-to-month tenancies, but they generally must give written notice far enough in advance for the change to take effect. In many cases that’s at least 30 days’ notice; if you’ve lived in the unit for a year or more, many changes require 60 days’ notice.
If the proposed change involves an increase in rent, California commonly requires:
- 30 days’ written notice if the increase is 10% or less, and
- 90 days’ written notice if the increase is more than 10% (often measured over a 12-month period)
Notice usually must be properly delivered (for example, in person or by mail). A text message or casual email may not count as legal notice unless you’ve agreed to receive notices electronically. If a landlord doesn’t follow the required notice rules, the new term may be unenforceable.
Protecting your rights as a tenant
In cities like San Francisco or Santa Rosa, local ordinances might offer even more protection for tenants. For instance, if a landlord removes a housing service like laundry access or storage, local rules may let tenants seek a rent reduction or other remedy. Even if the landlord provides the right notice, they may still be violating local housing laws if they fail to adjust the rent properly.
You have the right to a predictable living environment. Understanding these guidelines allows you to stand your ground when a landlord tries to overstep their authority.
