California Lease Requirements: What Every Landlord Must Include

California does not require leases to be in writing for terms under one year, but a well-drafted written lease is essential for protecting both landlords and tenants. This guide covers what must, should, and cannot be included.

Written vs. Oral Leases

Mandatory Lease Provisions

While California law doesn't prescribe a specific lease format, certain provisions are legally required or strongly recommended:

Required Disclosures (Must Be Part of Lease Package)

1. Lead paint disclosure — for pre-1978 properties
2. Megan's Law notice — sex offender database information
3. Bed bug disclosure — known infestation history
4. Flooding disclosure — if in a flood zone
5. Demolition intent — if applicable
6. Smoking policy — where smoking is and isn't allowed
7. AB 1482 notice — whether tenant protection applies or the property is exempt

Recommended Standard Clauses

• Parties — full legal names of landlord and all tenants
• Property description — address and unit number
• Term — start date, end date, and renewal terms
• Rent — amount, due date, payment method, and grace period
• Security deposit — amount and terms (within legal limits)
• Late fees — amount and when triggered (must be reasonable)
• Utilities — who pays for each utility
• Maintenance responsibilities — landlord vs. tenant obligations
• Entry provisions — referencing 24-hour notice requirement
• Pet policy — whether pets are allowed, deposits, or pet rent
• Subletting — whether subletting is permitted
• Parking — assigned spaces and rules
• Insurance — renter's insurance recommendations or requirements

Prohibited Lease Clauses

California law voids the following lease provisions:

1. Waiver of habitability — tenants cannot waive their right to a habitable dwelling
2. Waiver of legal rights — clauses that attempt to waive tenant rights under California law
3. Excessive late fees — fees that exceed a reasonable estimate of damages
4. Automatic rent acceleration — clauses making all future rent due upon a single late payment
5. Right-of-entry without notice — landlord entry without 24-hour notice (except emergencies)
6. Mandatory arbitration — in some cases, mandatory arbitration clauses in residential leases may be unenforceable
7. Security deposit waivers — clauses requiring tenants to waive their right to a refund

Lease Renewals and Month-to-Month Conversion

When a fixed-term lease expires and the tenant remains:

• The lease automatically converts to a month-to-month tenancy
• All original lease terms continue to apply
• Rent increases require proper notice (30 or 90 days)
• Termination requires proper notice (30 or 60 days depending on tenancy length)

Best Practices

1. Use a written lease for every tenancy — even month-to-month
2. Have an attorney review your template — especially for compliance with AB 1482
3. Include all required disclosures — as attachments or addenda
4. Keep signed copies — both landlord and tenant should retain copies
5. Update annually — review your lease template each year for legal changes
