You manage a portfolio and every one of its landlord responsibilities. Maybe 20 units, maybe 200. Something is about to break. Someone is about to stop paying.
Most weeks, that is just the job. Then a tenant falls three months behind, the owner wants the unit back, and you hand the file to counsel.
That is when the file gets read line by line.
In California, the eviction case is rarely lost at trial. It is lost months earlier, on a skipped repair, an unfiled notice, or a deposit rule nobody updated. Every one of your landlord responsibilities is a door. Leave it open and the tenant’s lawyer walks through it.
This checklist covers the landlord responsibilities that matter most in California, where Los Angeles adds its own layer, and the compliance gaps that turn a clean eviction into a contested one.
Why landlord responsibilities decide eviction cases
Here is the part most property managers underestimate. An Unlawful Detainer is a fast, narrow lawsuit about possession. The tenant cannot win by arguing they are a nice person. They win by showing the landlord did something wrong.
That is how California landlord tenant law is built. Your landlord rights are real, but they are conditional. The right to recover possession depends on having met your landlord responsibilities first.
So the defense playbook looks for three things:
- A habitability problem that offsets or eliminates the rent claimed
- A procedural defect in the notice, its service, or a local filing requirement
- A retaliation or discrimination story that reframes the eviction as punishment
Proactive compliance takes all three off the table before the case begins. That is the entire argument for this checklist.
The LA complication: two layers of rules, one portfolio
State law sets the floor. The City of Los Angeles builds on top of it, and the two layers do not line up neatly.
A unit in Los Angeles is typically covered by either the Rent Stabilization Ordinance (RSO) or the Just Cause Ordinance (JCO). Each carries its own notice, registration, and relocation rules. Units in unincorporated LA County answer to a different ordinance again.
If your portfolio spans Santa Monica, Glendale, Los Angeles, and unincorporated areas, you are not managing one set of landlord responsibilities. You are managing four.
Know which ordinance applies to every unit before you touch a notice. Evict Boss maintains a plain-English breakdown of Los Angeles eviction laws and the JCO for exactly this reason.
The landlord responsibilities compliance checklist
Work through this by property, not by memory. Put the date you verified each item in the file.
1. Habitability: the warranty you cannot waive
Habitability sits at the top of your landlord responsibilities. Every California residential lease carries an implied warranty of habitability. It cannot be signed away, and it is the most common defense raised in nonpayment cases. Civil Code Section 1941.1 lists the baseline: weatherproofing, plumbing, hot water, heat, electrical, clean and sanitary grounds, working locks, and more.
The list grew recently. Under AB 628, a working stove and refrigerator are now habitability requirements for leases entered into, amended, or extended on or after January 1, 2026. A recalled unit must be repaired or replaced within 30 days of notice of the recall.
Checklist:
- Every unit with a new, renewed, or amended lease since January 1, 2026 has a working stove and refrigerator, or a documented written tenant agreement to supply their own refrigerator
- Repair requests are logged with the date received, the date addressed, and the result
- Mold, pest, leak, and heating complaints get a documented response
- Code enforcement or LAHD inspection citations are closed out in writing
If a repair request sits unanswered in your inbox, assume it will be Exhibit A.
2. Security deposits: newer rules, easy mistakes
Deposit handling is one of the landlord responsibilities where templates fall behind the law. The rules changed and many forms did not.
- Deposits collected on or after July 1, 2024 do not exceed one month’s rent, unless the owner qualifies for the small-landlord exception
- Itemized statements and any refund go out within 21 days after the tenant vacates
- Move-in and move-out photos are taken and retained for tenancies covered by the newer photo documentation rules
- Deductions are limited to what Civil Code Section 1950.5 allows
Deposit disputes rarely stop an eviction on their own. They do hand the tenant leverage in settlement talks and a cross-claim at trial.
3. Entry and privacy
A landlord responsibility that sounds small until it becomes a harassment claim.
- Written notice of at least 24 hours before nonemergency entry
- Entry only for permitted purposes and during normal business hours
- A log of every entry, with the reason stated
4. Rent increases and registration
Illegal rent is not collectible rent. If the increase was improper, the 3-Day Notice demanding it can be defective.
- RSO units are registered with LAHD and annual fees are paid
- Increases stay within the allowable RSO percentage or the AB 1482 cap, whichever applies
- Increase notices use the correct notice period for the amount of the increase
- Required renter protection notices are posted or delivered
5. Notices and local filings
This is where Los Angeles evictions die most often. Procedural landlord responsibilities leave no room for a close call.
- The correct notice type is used for the reason: 3-Day Notice to Pay or Quit, 3-Day Notice to Perform Covenant or Quit, 30-Day Notice, or 60-Day Notice
- The 3-Day Notice demands rent only, with no late fees or utilities mixed in
- For City of Los Angeles units, unpaid rent exceeds one month of Fair Market Rent for the unit size before a nonpayment notice is served
- Every notice to terminate tenancy is filed with LAHD within three business days of service, per the LAHD eviction notice filing rules
- No-fault terminations have a Declaration of Intent to Evict filed and relocation assistance handled correctly
Skip the LAHD filing and the tenant has an affirmative defense. That is not a technicality you argue around. That is a case you refile.
6. Fair housing and anti-retaliation
These landlord responsibilities protect you from the argument that the eviction is really about something else.
- Screening criteria are written and applied the same way to every applicant
- Source-of-income rules are followed, including Section 8 voucher holders
- No adverse action follows closely after a tenant complaint, repair request, or code enforcement call without clear documentation of an independent reason
Civil Code Section 1942.5 presumes retaliation in some cases when a landlord acts within 180 days of protected tenant activity. Timing alone can shift the burden to you.
7. What your team must not do
Your landlord responsibilities include what your staff does on the owner’s behalf. Put this in writing for every leasing agent, maintenance tech, and on-site manager.
California law prohibits self-help eviction. Changing locks, shutting off utilities, removing doors or windows, removing a tenant’s belongings, and pressuring a tenant to leave are illegal and expose the owner to statutory penalties. The only lawful path to possession runs through the court and the Sheriff. A single frustrated employee can create more liability than a year of nonpayment.
Mistakes that get your eviction challenged
These are the patterns that show up again and again in contested files.
| Mistake | What the tenant argues |
|---|---|
| Open repair tickets at the time of the notice | Rent should be reduced or eliminated under the warranty of habitability |
| Late fees included in a 3-Day Notice | The notice overstates rent and is defective |
| Notice not filed with LAHD within three business days | Affirmative defense under the Los Angeles Municipal Code |
| Wrong ordinance applied to the unit | Wrong notice, wrong relocation amount, wrong process |
| Notice served shortly after a complaint | Retaliatory eviction |
| Deposit or rent increase above the legal limit | Unclean hands and a damages cross-claim |
Notice what these have in common. None of them are about the tenant’s behavior. All of them are about missed landlord responsibilities.
The fix is boring and it works. Audit before you serve. If a unit fails any line of this checklist, correct it first, then proceed. A two-week delay to clean the file is cheaper than a dismissal and a restart.
Build compliance into the workflow, not the crisis
Property managers who stay out of trouble treat landlord responsibilities as a recurring system, not a reaction.
- Quarterly: confirm ordinance coverage and registration status for every unit
- At every lease signing or renewal: check appliances, deposit limits, and required disclosures
- At every repair request: log it, schedule it, close it, photograph it
- Before every notice: run the unit through sections 4 and 5 of this checklist
Local figures change. Fair Market Rent thresholds, relocation amounts, and allowable increases are updated on a schedule. Check the LAHD Just Cause Ordinance page before relying on any number, including the ones in your own templates.
