California’s rental laws have evolved rapidly over the past several years, and for many landlords, keeping up has become increasingly difficult. While South Orange County cities such as Mission Viejo, Laguna Niguel, Rancho Santa Margarita, and Aliso Viejo do not impose local rent control ordinances beyond state law, California’s statewide regulations still apply and they are strictly enforced.
For rental property owners, misunderstanding rent control rules, exemptions, or notice requirements can lead to costly penalties, unenforceable rent increases, and legal disputes with tenants. This guide explains how California rent control works, how it applies in South Orange County, and what landlords must do to stay compliant.
What Is California Rent Control?
California’s statewide rent control framework was established under Assembly Bill 1482 (AB 1482), also known as the Tenant Protection Act of 2019. The law places limits on annual rent increases and introduces just-cause eviction requirements for many residential rental properties.

Key Goals of the Law
AB 1482 was designed to:
- Prevent excessive rent increases
- Reduce displacement of long-term tenants
- Create uniform tenant protections statewide
However, the law does not apply to every rental property, and this is where confusion often arises.
How Much Can Rent Be Increased Under California Law?
For covered properties, annual rent increases are capped at:
5% + local Consumer Price Index (CPI)
or
10% total, whichever is lower.
This cap applies over a rolling 12-month period, not per lease term.

Why This Matters in South Orange County
South Orange County has historically experienced strong rent growth. In recent years, some landlords accustomed to higher increases have unknowingly exceeded legal caps, especially when renewing leases or transitioning month-to-month tenants.
Which Properties Are Exempt From Rent Control?
One of the most misunderstood aspects of AB 1482 is property exemptions.
Common Exemptions Include:
- Single-family homes
- Condominiums
- Townhomes
- Newer construction (generally properties built within the last 15 years)
However, and this is critical, many exemptions only apply if the landlord provides proper written notice to the tenant.
The Exemption Notice Requirement
Even if your property qualifies for an exemption, California law requires landlords to provide a specific exemption disclosure in the lease or via written notice.
Failure to do so can result in:
- The property being treated as subject to rent control
- Rent increases being deemed invalid
- Potential tenant claims for overpayment
The exemption notice language is outlined in California Civil Code Section 1947.12.
Just Cause Eviction Rules Explained
In addition to rent caps, AB 1482 introduced just-cause eviction requirements for covered properties.
What Is “Just Cause”?
Just cause generally falls into two categories:
- At-fault evictions (nonpayment of rent, lease violations, nuisance)
- No-fault evictions (owner move-in, substantial remodel, withdrawal from rental market)
Each category carries specific notice requirements and, in some cases, relocation assistance obligations.

Why Procedure Matters
Even when a landlord has a valid reason, improper notice, incorrect timelines, or missing documentation can invalidate an eviction and force the process to start over.
Do Local South Orange County Cities Have Additional Rent Control?
As of now, Mission Viejo and most South Orange County cities do not have local rent control ordinances beyond state law. This is different from parts of Los Angeles County and some Bay Area cities.
However, landlords must still comply with:
- State rent caps (when applicable)
- State just-cause requirements
- Fair housing laws at the federal and state level
Because local laws can change, landlords should monitor city council actions and housing policy updates regularly.
Common Rent Control Mistakes Landlords Make
Even well-intentioned landlords frequently make compliance errors, including:
- Assuming a property is exempt without issuing proper notice
- Increasing rent twice within a 12-month period
- Miscalculating allowable CPI increases
- Using outdated lease templates
- Serving incorrect notices
These mistakes often surface only after a tenant disputes an increase or consults a tenant advocacy organization.
How Rent Control Impacts Rental Strategy in South OC
Rent control doesn’t eliminate profitability, but it does change the strategy.
Successful South Orange County landlords focus on:
- Pricing units correctly from the start
- Retaining good tenants longer
- Improving property condition to justify market rent
- Ensuring full compliance to avoid disputes
Professional property management plays a key role in balancing rental performance with legal compliance.
Why a Professional Rental Analysis Matters More Than Ever
A proper rental analysis helps landlords not only identify market rent but also evaluates:
- Whether your property is subject to rent control
- How much rent can legally be increased
- Current market demand at various price points
- Opportunities to maximize income within legal limits
This insight helps landlords make confident, defensible decisions.
