Lease Addendums California Renters Should Review Carefully

When you rent in California, your lease agreement may include additional documents called addendums. These addendums can significantly affect your rights and responsibilities—sometimes even more than the main lease itself. Understanding these addendums helps prevent misunderstandings and ensures you know what you are agreeing to.

What Are Lease Addendums?

A lease addendum is an extra document added to your rental agreement that lays out additional terms, rules, or clauses. Addendums are legally binding as long as they don't conflict with California law. They are common in apartment rentals, single-family homes, and even room rentals.

Common Lease Addendums in California

Some of the most common lease addendums that California renters may encounter include:

• Pet Addendum – Specifies if pets are allowed, and outlines rules, deposits, or restrictions.
• Smoking Policy Addendum – States whether smoking (including cannabis) is permitted on the property.
• Utility Addendum – Details who is responsible for paying which utilities (gas, electric, water, etc.).
• Bed Bug Addendum – Mandatory in California; educates tenants about bed bug identification and reporting responsibilities. California Bed Bug Addendum (Official Form)
• Mold Disclosure Addendum – Required to warn about potential mold hazards and maintenance advice for moisture prevention.
• Lead-Based Paint Disclosure – Required for properties built before 1978, disclosing known information about lead hazards. EPA Sample Disclosure Forms
• Renters Insurance Addendum – States whether you must carry rental insurance and sets coverage requirements.
• Rent Increase Addendum – Notifies of legal changes in rent during term or at renewal; must follow state/local rent control rules.

Each of these can change the way your lease works. It's critical to read and understand every addendum before signing, as they are enforceable by law.

Important Required Addendums & Disclosures for Renters

California law requires certain addendums and disclosures be included with every residential lease. These include:

• Bed Bug Addendum (see above)
• Mold Disclosure as per California Civil Code Section 26147
• Lead-Based Paint Disclosure – For buildings pre-1978 (HUD Guidance)

Landlords must provide these forms and cannot charge you for the required disclosures. If you do not receive a required form or disclosure, you may report it to your local authority or ask for the documentation.

Where to Find Official Forms

• Bed Bug Addendum
  Official California Bed Bug Addendum (no form number)
  When and How Used: Your landlord should give you this before you sign the lease. For example, if you’re moving into an apartment, the form explains how to spot and report bed bugs, which both you and your landlord are responsible for.
• Mold Disclosure
  There’s no numbered state form, but landlords should provide a written disclosure summarized under California Civil Code Section 26147.
  When and How Used: This must be provided at lease signing or renewal to warn of potential mold risks.
• Lead-Based Paint Disclosure Form
  Sample Lead-Based Paint Disclosure Form (HUD/EPA)
  When and How Used: Landlords provide this if the building was constructed before 1978, letting tenants know of any known lead hazards or prior lead tests.

How Lease Addendums Affect California Tenants

Signing a lease addendum means you are legally agreeing to its terms. However, an addendum cannot override your rights under California law, such as:

• Your right to habitable housing (safety, repairs, basic utilities)
• Limits on security deposits – maximum of two months’ rent (unfurnished) or three months’ rent (furnished)
• Proper notice periods for entry, eviction, or rent increases

If you receive a new addendum after move-in, your landlord usually needs your written consent. Never sign anything you don’t understand—ask for clarification, seek legal support, or check with official tenant resources if needed.

Tips for Reviewing Lease Addendums

• Read every addendum fully before signing
• Ask for plain-language explanations for any technical or legal terms
• Request copies of all documents for your records
• If uncertain, call a renter support hotline or local legal aid

Filing a Complaint About Illegal Addendums or Lack of Disclosure

If you think an addendum violates your rights or your landlord withholds required disclosures, you can:

• Contact your local city or county housing department
• File a formal complaint with the California Department of Consumer Affairs
• If needed, seek mediation or file in Small Claims Court for certain violations

FAQ: California Lease Addendums and Renter Rights

1. Can a landlord make me sign a new lease addendum after I’ve moved in?
   Landlords generally need your written consent to add new terms. You are not required to accept changes after signing the original lease unless it's legally mandated.
2. What happens if an addendum conflicts with California law?
   If an addendum violates state law or the California Civil Code, it is not enforceable—even if you signed it.
3. Are pet, smoking, and utility addendums mandatory?
   No. These addendums are optional and depend on landlord policy. Required addendums include bed bug, mold, and (for older buildings) lead-paint disclosures.
4. Where do I file a complaint about a problematic lease addendum?
   Contact your local housing department or the Department of Consumer Affairs. You can also consult the California Courts Self-Help Center for guidance.
5. Can a landlord evict me for refusing to sign a new addendum?
   No, unless the addendum is legally required. Speak with your local tenant resource or legal aid if pressured.

Conclusion: Key Takeaways for California Renters

• Review every lease addendum before signing; ask questions if unclear.
• California requires certain disclosures (bed bug, mold, lead paint for older units).
• Always compare addendum terms with the California Civil Code Tenant Protections.

If you find an addendum that seems unfair or illegal, get advice from an official California housing resource before agreeing.
