California landlords face more legal obligations than property owners in almost any other state. Understanding and meeting these responsibilities isn't optional—failure to comply can result in lawsuits, penalties, and invalidated lease provisions. This comprehensive checklist covers every major landlord obligation under California law.
Habitability Requirements
California's implied warranty of habitability requires landlords to maintain rental units in livable condition. Specifically, you must provide:
- Weatherproofing: Roof, walls, windows, and doors that protect against rain and weather
- Plumbing: Functioning hot and cold water, sewage disposal, and working fixtures
- Heating: Adequate heating facilities in good working order
- Electrical: Safe electrical wiring and functioning lighting
- Sanitation: Clean premises free of debris, garbage, and vermin
- Safety: Working smoke and CO detectors, secure locks, and safe conditions
- Floors, stairs, railings: Safe and in good repair
Failure to maintain habitability can result in tenant rent withholding, repair-and-deduct actions, or lawsuits for damages.
Required Disclosures
California requires landlords to provide numerous disclosures before or at lease signing:
Required for pre-1978 buildings; includes EPA pamphlet
Known infestations in past year
Known mold presence and health risks
If property is in flood hazard area
If demolition permit applied for
Notice of Megan's Law database availability
Recent pest control company reports
Designation of smoking/non-smoking areas
Security Deposit Obligations
California strictly regulates security deposits. Landlords must limit deposits to one month's rent (for most properties as of 2024), return deposits within 21 days of move-out, provide itemized statements of any deductions with receipts, allow pre-move-out inspection upon tenant request, and never commingle deposits with personal funds (best practice).
