So you’ve become a landlord—maybe by chance, maybe by choice. Either way, your lease is the foundation you’ll be building on.

But many DIY landlords unknowingly rely on outdated or non-compliant templates that can do more harm than good.

A bad lease won’t just cost you rent—it could land you in court. In this post, we’ll cover the essential clauses your lease needs, common legal pitfalls to avoid, and how to protect yourself and your rental from unnecessary risk.

Your Lease Isn't Just a Form—It's a Legal Contract

Your lease is one of the most important tools you have as a landlord. But many new or self-managing property owners unknowingly rely on generic templates found online—without realizing the risks they may be taking.

To avoid disputes and legal issues, it’s worth having your lease reviewed by someone who understands both state and local laws. A well-written lease helps establish a clear, professional relationship with your tenants and sets expectations from day one. It reduces liability, protects your investment, and ensures everyone knows their responsibilities—and the consequences of not meeting them.

Must-Have Clauses That Belong in Every California Lease

Ambiguity is your worst enemy when it comes to lease terms and clauses. Spelling out protections and procedures in advance creates peace of mind for both landlords and tenants—helping you avoid unnecessary stress and legal exposure down the road.

Rent and late fees—your lease should specify the monthly rent amount, recurring due date, and accepted forms of payment, such as a mailed check or app payment. It should also include the grace period for late payments and relevant penalties or fees.

Entry notice—lease agreements must protect a tenant's right to privacy and a landlord's right to access the property. In non-emergency situations, landlords must give 24 hours' written notice before entering. For move-out inspections, 48 hours' notice is required. In emergencies, you may enter without notice to address urgent concerns.

Maintenance responsibilities—from lawn care and routine upkeep to pest infestations and major repairs —tenants should know what they're responsible for and when to contact their landlord or property manager for assistance.

Security deposits—California law requires security deposits to be returned within 21 days of move-out. Tenants must also receive an itemized list of deductions made. In some jurisdictions, landlords are also required to pay interest on withheld deposits, so make sure your lease reflects local rules.

Outdated or Illegal Clauses That Could Land You in Trouble

Just because a clause appears in your lease—and a tenant signed it—doesn't mean you can enforce it. This precedent was set by "Henirioulle v. Marin Ventures" where a court ruled that if clauses violate state and local laws, landlords will still be held liable.

Many DIY, downloaded, and inherited leases include outdated language that puts you at risk. Check your lease for these illegal clauses:

Waiving Tenant Rights or Habitability Standards

In California, tenants have the right to live in a safe and habitable unit, regardless of what their lease states. Trying to waive that right (even subtly) can leave you vulnerable to legal action. 

Exorbitant Fees and Eviction Threats

Tenant penalties must be reasonable, clearly defined, and in line with California law. Vague terminology related to eviction and excessive fees will get shot down in court. 

Legal Traps in Action: Real Cases That Cost Landlords

"Henirioulle v. Marin Ventures" isn't the only California court case that reveals what you could expect if you end up in a legal dispute. In Garcia v. D/AQ Corp, a tenant was hurt on a rental property. Their lease had an "exculpatory clause" stating the landlord wasn't responsible for injuries, but the court disagreed. This case reinforced that it's a landlord's responsibility to maintain a safe space for their tenants. 

In Graylee v. Castro, a landlord issued a $600 fee for a tenant who stayed past their lease end date. The court found that the penalty was unfair, too high, and more punishment than reimbursement for a provable damage.
