You are not covered under the CA Tenant Protection Act
Unfortunately, you are not covered under either of Oakland’s Rent Control Ordinance or the California Tenant Protection Ordinance. However, you can try a few different things:
Ask for more time or try to negotiate with the landlord.
If you live in a building with other tenants, organize with them to try to keep your landlord from raising the rent.
If this rent increase feels unfair due to the number of repair issues the landlord hasn’t fixed, then try to pay the rent increase and follow the steps in the repair section to get repairs done [Repairs]. But, if you are thinking of withholding rent then you should talk to a lawyer because this can be very risky.
Without any rent control:
On a month-to-month or other periodic tenancy, or at the end of a year lease, your landlord can increase your rent.
If you have a lease, your landlord cannot change its terms or raise your rent until the lease ends.
There is no limit to the amount your landlord can raise your rent as long as they give you proper notice: 30 day notice for a 10% or less increase, 60 day notice for a rent increase more than 10% of your current rent for a fixed term lease, 90 day notice for a rent increase more than 10% of your current rent for periodic tenancies.
