Eight Things a Modern California Lease Should Address

Most California landlord–tenant disputes the firm sees trace back to a lease that was generic, outdated, or silent on the issue at the heart of the dispute. The fix is rarely a fifty-page rewrite. It is a working lease that addresses, in plain language, the eight or ten places California law has moved or where written policies head off arguments later. Here is a starter list of what a modern California residential lease should cover.

1. Rent, late fees, and grace periods that comply with current law

Late-fee provisions in California must reflect the landlord's reasonable estimate of damages caused by the late payment. Flat percentages and aggressive escalators are routinely struck down in small-claims and unlawful-detainer cases. The lease should state the rent amount, due date, any grace period, and a late fee that is defensible — not just one that looks tough.

2. AB 1482 status, where applicable

The Tenant Protection Act of 2019 (AB 1482) caps rent increases and limits terminations for many California rentals. Several categories of property are exempt — single-family homes owned by individuals, alteration-protected new construction, and others — but the exemption only applies if the lease contains a specific written notice of exempt status. A lease that quietly assumes exemption without delivering the required notice may forfeit it. Whether AB 1482 applies and whether the exemption notice has been served is one of the first things that comes up in a contested termination.

3. The one-month security deposit cap

As of July 1, 2024, most California residential security deposits are capped at one month's rent under Civil Code § 1950.5 (see our prior post on AB 12). The deposit clause should match — one month, no separate pet deposit on top, no separate non-refundable "cleaning fee" structured as a side payment.

4. Habitability and repair-request procedure

California's implied warranty of habitability cannot be waived, but a clear written procedure for how repair requests are made and how the landlord will respond reduces the risk of a self-help repair-and-deduct claim and creates a paper trail that helps in any later dispute. A simple lease provision that names a single point of contact, an email or portal address, and a turnaround commitment for non-emergency requests often does more for both sides than a stack of legal boilerplate.

5. Just-cause grounds and notice requirements

For AB 1482 covered units, terminations after twelve months of tenancy generally require a written, specified just cause and may require relocation assistance for no-fault terminations. The lease should reflect the categories — at-fault and no-fault — and confirm that the landlord will follow the statutory process. Even where AB 1482 does not apply, owner-move-in, substantial-remodel, and similar grounds have their own notice and proof requirements that some local ordinances tighten further.

6. Pets, support animals, and assistance animals

Pets are negotiable. Assistance animals are not — under federal and California fair-housing law, a tenant who provides reliable documentation of a disability-related need is generally entitled to a reasonable accommodation, and pet rent and additional pet deposits do not apply to assistance animals. A pet provision that does not distinguish between the two invites a fair-housing claim. The cleaner approach is a pet provision plus a separate written accommodation policy that states what documentation the landlord will accept and how decisions are made.

7. Smoking, cannabis, and short-term rentals

California has localized rules on smoking inside rental units, cannabis cultivation, and short-term rentals (Airbnb-style use). Local ordinances vary. A modern lease should set a clear policy on each — even a simple "no smoking of any substance, including cannabis, anywhere on the premises" — rather than relying on the local ordinance to do the work.

8. Communications, electronic notices, and entry

California Civil Code § 1954 sets the rules for landlord entry: 24-hour written notice for non-emergency entries, with limited exceptions. The lease should confirm the notice channel — written, email, text — and state the tenant's email and mobile contact information. If the lease allows electronic notice, it should say so explicitly so disputed late-rent or termination notices are not voided by an avoidable form defect.

And one more: a clean signature page

This is mechanical, but worth saying. A lease that bundles co-tenants on different signature lines, omits a property manager-as-agent designation, or fails to identify which exhibits and addenda are part of the agreement is the kind of document opposing counsel can pick at for hours. A short, clean cover and signature page makes the rest of the document harder to attack.

What this is not

This is a working list, not a substitute for a lease. It does not cover commercial leases, rent-controlled units in jurisdictions with their own ordinances, or specialty programs (Section 8, BMR, etc.) that have additional requirements. Each engagement starts with what kind of property is being leased, where, to whom, and for what term — and the lease is built from those facts.
