California's rent control laws represent some of the most comprehensive tenant protections in the United States. For Simi Valley renters, understanding these laws is crucial to knowing whether your landlord can raise your rent, by how much, and what notice they must provide. California's approach to rent control has evolved significantly over the past decade, with major legislation fundamentally changing what protections are available. This guide breaks down the current rent control landscape affecting Simi Valley tenants and explains what you need to know.

The Evolution of California Rent Control

California's rent control history is complex. For decades, the state had strong rent control laws, but the Costa-Hawkins Rental Housing Act of 1995 severely limited these protections by exempting most properties built after 1995. This meant that newer apartments and homes had essentially no rent control protections. However, the landscape changed dramatically with the passage of AB 1482 in 2019, which became effective January 1, 2020. AB 1482, also known as the Tenant Protection Act, restored statewide rent control protections regardless of when a property was built.

This change has profound implications for Simi Valley renters. Before AB 1482, tenants renting newer apartments or homes had virtually no protection against arbitrary rent increases. Now, all renters in California have baseline protections, though some cities and local jurisdictions may have additional restrictions that offer even more protection.

AB 1482: The Tenant Protection Act

AB 1482 applies to nearly all residential rental units in California, with very few exceptions. The law prohibits arbitrary rent increases and provides other tenant protections. The primary rent increase protection limits annual increases to five percent plus inflation, with a combined maximum of ten percent per year. This applies statewide, meaning that regardless of when your Simi Valley apartment was built or other circumstances, your landlord cannot raise rent by more than this amount annually.

The five percent plus inflation calculation matters. In 2026, with higher inflation rates, the combined cap of ten percent may be the limiting factor. Your landlord must provide at least thirty days' notice for any rent increase. If the increase is substantial—greater than ten percent in a single year, which would violate the law—they must still provide proper notice. If your landlord attempts to increase rent beyond the legal limits, you can dispute it and potentially recover excess amounts.

Local Ordinances Beyond AB 1482

While AB 1482 provides statewide protections, some cities and counties impose even stricter limits. Simi Valley may have local rent control ordinances that provide additional protections. Some jurisdictions cap rent increases at lower percentages or require landlords to justify increases with documentation of actual costs. Before signing a lease or after receiving a rent increase notice, check whether Simi Valley or Ventura County has local rent control ordinances that provide additional protections beyond the state minimum.

You can find this information by contacting the City of Simi Valley's Housing or Community Development Department, or by checking their website. Local tenants' rights organizations also maintain updated information about rent control in specific areas. These extra protections can be significant and may mean your landlord cannot legally increase rent at all in some circumstances.

Just-Cause Eviction Requirements

Closely related to rent control, AB 1482 also requires "just cause" for evictions. This means your landlord cannot evict you simply because they want to—they must have a legal reason. Valid reasons include non-payment of rent, material lease violations that aren't cured after notice, nuisance behavior, criminal activity, failure to provide required notices, and several others. Importantly, landlords cannot use eviction threats as a way to force you to accept illegal rent increases.

If your landlord attempts to evict you in retaliation for asserting your rent control rights, that eviction is illegal. Similarly, if they try to evict you for declining an illegal rent increase, you have strong legal protections. Documentation of your communications about rent increases can help prove retaliation if an eviction follows.

Notice Requirements for Rent Increases

Proper notice is essential to rent increase validity. California law requires landlords to provide thirty days' notice for increases less than ten percent and sixty days' notice for increases of ten percent or more. The notice must be in writing and delivered according to legal standards—typically by mail, in person, or electronically if you've agreed to that method. Notice must clearly state the amount of the increase, the effective date, and the new rent amount.

If your landlord fails to provide proper notice, the rent increase may not be legally binding. If they demand payment of the increased rent without proper notice, you can refuse payment and potentially challenge the increase. Keep all documentation of rent increase notices, including when you received them and what they stated.

Exemptions and Limitations

AB 1482 has some exemptions worth knowing about. Single-family homes where the owner lives and there's only one tenant are exempted if the owner occupies the property. New construction built after January 1, 2019, is exempt from rent control for fifteen years from the date it first became available for occupancy—however, this exemption expires and does not apply indefinitely. Owner-occupied buildings with four or fewer units also have some exemptions.

If your unit falls into one of these categories, it may not have rent control protection. However, you may still have protections under fair housing law and other tenant protections. Verify your unit's status to understand which protections apply to you.

Challenging Illegal Rent Increases

If your landlord attempts to increase rent beyond legal limits, you have several options. The most straightforward is to refuse payment of the excess and document your objection. Many landlords back down when confronted with tenants who know their rights. If the landlord pursues legal action, you can defend yourself in court by arguing the increase is illegal.

You can also file complaints with local housing authorities or tenant advocacy organizations. These agencies can investigate and may pressure landlords to comply with the law. In some cases, you may recover the excess rent paid. An attorney specializing in tenant rights can also help you understand your options and pursue claims for illegal increases.

Protecting Yourself Going Forward

To protect yourself as a Simi Valley renter, document everything related to rent. Keep copies of your lease, all rent increase notices, and rent payment records. Understand the current rent control laws that apply to your specific unit. If you receive a rent increase notice, verify that it complies with legal requirements before paying the increased amount. Consider reaching out to local tenants' rights organizations if you have questions or concerns about whether an increase is legal.
