You manage more than one property. Maybe five. Maybe fifteen. Each one sits under its own mix of state statutes, county rules, and city ordinances, and none of them stay still for long.
A notice that worked at your Culver City building can get your case thrown out in Koreatown. A deposit limit you learned three years ago changed in 2024. Landlord-tenant laws in California move fast, and a portfolio manager who tracks one property’s rules instead of all of them is one filing away from a dismissed case.
This guide breaks down the landlord-tenant laws that apply to every unit in your portfolio: deposits, habitability, rent caps, notice periods, and the changes from the last two years that catch even experienced managers off guard.
What California Landlord-Tenant Law Actually Covers
People often search for a single “California landlord and tenant act,” expecting one tidy statute. It does not exist. California landlord tenant law is a patchwork built from several sources at once, and a property manager has to know all of them, not just the popular one. Civil Code sections 1940 through 1954.05 govern deposits, habitability, and a landlord’s right of entry. The Tenant Protection Act of 2019 sets a statewide rent cap and just cause standard. Local ordinances then layer on top in dozens of California cities, Los Angeles among the strictest.
Landlord tenant rights come from whichever layer applies to a given address, and when two layers conflict, the stricter one controls. That is the whole game for a portfolio manager: figuring out which layer governs each unit before you act.
Why Los Angeles Makes This Harder for Property Managers
Los Angeles adds a layer most California counties do not have. The Rent Stabilization Ordinance, or RSO, covers buildings constructed before October 1978 and caps annual increases below the statewide ceiling. The Just Cause Ordinance restricts why and how a tenancy can end, and it often triggers relocation assistance that the statewide law does not require. Unincorporated Los Angeles County runs its own version, with its own numbers. Santa Monica and West Hollywood run separate systems entirely.
For a manager with units scattered across the county, the real compliance question is not what California landlord-tenant laws say in general. It is what the law says about this address, built in this year, sitting in this jurisdiction. Run every property against our breakdown of Los Angeles eviction laws before you serve a single notice. The wrong ordinance applied to the right building is how landlords lose cases they should have won.
The Landlord-Tenant Laws Every Property Manager Needs on Their Checklist
Here is what actually shows up in a compliance audit, unit by unit.
Security Deposit Limits
Assembly Bill 12 changed the security deposit rules for nearly every California rental as of July 1, 2024. The cap is now one month’s rent, furnished or not, for most landlords.
A narrow exception applies to a small owner, meaning a natural person or an LLC made up entirely of natural persons who own two or fewer properties totaling four or fewer units. That owner can collect up to two months’ rent. Active service members are capped at one month’s rent regardless of owner size.
Deposits must be returned within 21 days of move-out with an itemized statement. Retaining a deposit in bad faith can expose a landlord to damages of up to twice the amount withheld, on top of the deposit itself. Applying an outdated deposit policy to newer leases across a portfolio is exactly the kind of gap that compounds with every unit.
The Habitability Duty
California Civil Code Section 1941 spells out one of the most basic landlord responsibilities in the code: keep the rental fit to live in. Working plumbing, heat, weatherproofing, and freedom from pest infestation and structural hazards are not optional and not negotiable through a lease.
Deferred maintenance is one of the most common defenses tenants raise once an Unlawful Detainer (UD) case reaches court. A judge who sees months of ignored repair requests next to a nonpayment notice does not read the case the way the landlord expected. Document every repair request and every response.
Right of Entry
Civil Code Section 1954 sets the rules for entering an occupied unit. Written notice with the date, approximate time, and purpose of entry is required, and 24 hours is presumed reasonable in the absence of evidence otherwise. Entry outside of normal business hours needs the tenant’s consent at the time, not just written notice.
Landlords who skip this step hand a tenant’s attorney a harassment argument for free. It rarely decides the whole case, but it slows everything down, and slow is expensive.
Rent Increase Caps
The Tenant Protection Act of 2019, still widely searched as the California landlord and tenant act, caps annual rent increases at 5% plus the regional Consumer Price Index, up to a ceiling of 10%, for units 15 years or older and not otherwise exempt. Single-family homes and condos only qualify for an exemption if the owner gives the specific statutory notice required under Civil Code Section 1946.2. Skip that notice and the unit stays covered no matter who owns it.
Local ordinances can set a lower cap, and the lower number governs. Los Angeles Rent Stabilization Ordinance units, for instance, follow a separate formula tied to local CPI that typically lands well under the statewide ceiling. Confirm the current percentage with the Los Angeles Housing Department before sending any increase notice, and review the underlying statute through California’s Legislative Information site.
Just Cause Eviction Requirements
Once a tenant has occupied a unit for one year, the Tenant Protection Act requires “just cause” to end the tenancy, whether the unit sits in Los Angeles or Redding. At-fault reasons include nonpayment of rent, lease violations, and nuisance. No-fault reasons include owner move-in, an Ellis Act withdrawal, or a substantial remodel that requires the unit to sit vacant.
No-fault terminations generally require relocation assistance equal to one month’s rent, paid to the tenant at or before the time notice is served. Skip that payment and the notice itself can be challenged. This is where the lease drafting side of an eviction attorney’s work matters as much as the courtroom side: a termination built on the wrong ground, or missing the required payment, rarely survives a motion to quash.
Notice Periods at a Glance
| Notice | When It Applies |
|---|---|
| 3-Day Notice to Pay or Quit | Tenant has not paid rent |
| 3-Day Notice to Perform Covenant or Quit | Curable lease violation |
| 30-Day Notice | Tenancy under one year, or certain just-cause terminations |
| 60-Day Notice | Tenancy of one year or more |
Serve the wrong length under California landlord-tenant law and the clock resets. Once the notice period expires without a cure, the next step is a UD filing with the Superior Court. The tenant then has 10 days to file a response, not the five days many landlords still expect from older guidance. The California Courts self-help eviction guide walks through the filing steps in detail.
Two Recent Changes That Catch Managers Off Guard
Two 2025 changes matter for anyone running a portfolio. First, the tenant’s response window in a UD case grew from five days to 10 days after service, which pushes back every downstream deadline in the case. Second, court records in limited UD cases are now masked from public view until a landlord wins a judgment within 60 days of filing, which changes how background screening on prospective tenants actually works. The California Department of Real Estate’s landlord and tenant guide covers both changes along with several others from the same legislative session.
This is landlord-tenant law in its most literal form: the rules keep moving, and last year’s version does not protect you today. Landlord responsibilities do not shrink because the law gets more complex. They just get harder to track without help.
Mistakes That Kill Compliance Across a Portfolio
These are the landlord-tenant law mistakes that show up most often across a multi-property portfolio:
- Reusing one property’s notice template everywhere. A 3-Day Notice built for a non-RSO unit will not hold up the same way on a pre-1978 building.
- Missing the single-family exemption notice. Without the exact statutory language in Civil Code Section 1946.2, a single-family rental stays covered by the statewide cap and just cause rules even if the owner assumed otherwise.
- Collecting a deposit above the AB 12 cap on units that do not qualify for the small-owner exception.
- Ignoring the added Los Angeles layer on pre-1978 buildings. The RSO applies on top of state law, not instead of it.
- Serving a 30-Day Notice where the law requires 60 days, usually because a manager did not check how long the current tenant has actually lived there.
- No paper trail on habitability repairs, which hands a tenant’s attorney a ready-made defense in court.
