California Landlord-Tenant Law Essentials for the Real Estate Exam

Last updated: April 2026

For aspiring real estate professionals in the Golden State, mastering property laws is non-negotiable. Whether you plan to specialize in property management, commercial leasing, or residential sales, understanding the rights and responsibilities of both property owners and renters is a critical component of your education. This guide covers the foundational rules you need to know, serving as a vital supplement to your Complete California Exam Guide.

The California Tenant Protection Act (AB 1482)

The California Tenant Protection Act of 2019 (commonly referred to as AB 1482) fundamentally changed the landscape of residential leasing in the state. Exam candidates must understand its two primary pillars: statewide rent control and "just cause" eviction protections.

Statewide Rent Caps

Under AB 1482, annual rent increases for covered units are strictly capped. Landlords cannot raise the rent over a 12-month period by more than 5% plus the local rate of inflation (Consumer Price Index or CPI), or 10% total, whichever is lower.

Exam Scenario: If the CPI in San Diego is 3%, the maximum allowable rent increase for an AB 1482-covered property is 8% (5% + 3%). If the CPI jumps to 7%, the maximum increase is capped at the hard ceiling of 10%, rather than 12%.

Just Cause Evictions

Once a tenant has continuously and lawfully occupied a residential property for 12 months, the landlord can only evict them for "just cause." The law divides just cause into two categories:

  • At-Fault Just Cause: The tenant has done something wrong. Examples include failure to pay rent, breach of a material lease term, committing waste (damaging the property), or using the property for an unlawful purpose.
  • No-Fault Just Cause: The tenant has done nothing wrong, but the landlord needs the unit back. Examples include the owner (or their direct relative) moving into the unit, withdrawing the property from the rental market (Ellis Act), or substantial remodeling. Crucial Exam Fact: In a no-fault eviction, the landlord must provide the tenant with relocation assistance equal to one month's rent.

Security Deposits (Civil Code Section 1950.5)

Security deposit regulations are heavily tested on the California real estate exam. Recent legislation has simplified these rules, making it essential to know the most current limits.

Following the implementation of AB 12 (effective July 1, 2024), California landlords are generally restricted to charging a maximum of one month's rent for a security deposit, regardless of whether the unit is furnished or unfurnished. (Note: There is a narrow exception for small landlords who own no more than two properties totaling no more than four units, who may charge up to two months' rent under specific conditions).

The 21-Day Rule

According to California Civil Code Section 1950.5, a landlord has exactly 21 days after a tenant vacates the premises to either:

  1. Refund the security deposit in full, or
  2. Provide an itemized statement detailing any deductions along with the remaining balance of the deposit.

Deductions can only be made for unpaid rent, cleaning the unit to the level of cleanliness it was in at the start of the tenancy, and repairing damages beyond normal wear and tear.

The Implied Warranty of Habitability

Under California Civil Code Section 1941.1, every residential lease contains an "implied warranty of habitability." This means the landlord is legally obligated to keep the property in a livable condition. Essential requirements include:

  • Effective waterproofing and weather protection of roof and exterior walls.
  • Functioning plumbing, gas, and heating facilities.
  • Hot and cold running water.
  • Adequate trash receptacles.
  • Floors, stairways, and railings maintained in good repair.

Tenant Remedies: Repair and Deduct

If a landlord fails to make necessary habitability repairs after being given reasonable notice (usually 30 days, but less for emergencies), the tenant may use the "repair and deduct" remedy. The tenant can hire a professional to fix the issue and deduct the cost from their next month's rent.

Exam Limitation: The cost of the repair cannot exceed one month's rent, and the tenant can only use this remedy twice in any 12-month period.

The Eviction Process: Unlawful Detainer

Landlords cannot engage in "self-help" evictions in California. Changing locks, shutting off utilities, or physically removing a tenant's belongings are illegal acts that carry severe financial penalties. The legal process for removing a tenant is called an Unlawful Detainer action.

The process always begins with a formal written notice. The type of notice depends on the situation:

Statutory Notice Periods for CA Evictions (Days)

If the tenant fails to comply with the notice, the landlord files an Unlawful Detainer lawsuit. If the landlord wins, the court issues a "Writ of Possession," which is executed by the local Sheriff's Department—the only entity legally authorized to physically remove a tenant.

Intersecting Real Estate Concepts

Landlord-tenant laws do not exist in a vacuum; they intersect with several other key areas of real estate practice:

  • Property Valuation: When evaluating a rental property's income potential for an investor, understanding rent caps is crucial. A property with rents severely below market value will take years to stabilize due to AB 1482 limits. For more on property valuation, review our California comparative market analysis guide.
  • Judgments and Debt: If a landlord wins a monetary judgment in an Unlawful Detainer case for unpaid rent, they may record an abstract of judgment, creating a lien against the tenant's real property. Learn how these fit into the broader picture in our guide to California liens and their priority.
  • Agency Relationships: When a real estate licensee acts as a property manager, they are an agent of the landlord. Fiduciary duties apply just as they do in sales. To understand these duties in depth, study California buyer vs. seller representation.

Frequently Asked Questions

What is the maximum security deposit a landlord can charge in California?

As of July 2024 (under AB 12), the maximum security deposit for a residential rental in California is generally capped at one month's rent, regardless of whether the property is furnished or unfurnished. There are limited exceptions for small landlords.

How many days does a landlord have to return a security deposit?

Under California Civil Code 1950.5, landlords have exactly 21 days after the tenant vacates the property to return the security deposit in full or provide an itemized list of deductions along with any remaining balance.

Can a landlord evict a tenant simply because the lease expired?

In many cases, no. Under the Tenant Protection Act (AB 1482), if a tenant has lived in the unit for 12 months or more, the landlord must have "just cause" (either at-fault or no-fault) to terminate the tenancy, even if a fixed-term lease has expired.

What is a "No-Fault" eviction under AB 1482?

A no-fault eviction occurs when the tenant has not violated the lease, but the landlord needs the unit back for a legally permissible reason, such as the owner moving in, substantial remodeling, or removing the property from the rental market. The landlord must pay the tenant one month's rent as relocation assistance.

What is the "Repair and Deduct" rule?

If a landlord fails to maintain a habitable property after reasonable notice, a tenant can pay for the repairs themselves and deduct the cost from their rent. The repair cost cannot exceed one month's rent, and this remedy can only be used twice in a 12-month period.

What is an Unlawful Detainer?

An Unlawful Detainer is the formal legal court process a landlord must use to evict a tenant in California. "Self-help" evictions (like changing locks or shutting off utilities) are strictly illegal.
