California Landlord Compliance Checklist 2026: What Every Landlord Must Know

California landlord-tenant law is one of the most complex regulatory frameworks in the country. Staying compliant protects your investment, prevents costly legal exposure, and keeps your eviction cases from getting dismissed on procedural grounds. Here are the core compliance requirements every California landlord must understand in 2026.

1. Written Lease Agreements

California law requires written rental agreements for tenancies of 12 months or longer. Even for month-to-month tenancies, a written lease is essential. Your lease must include the names of all tenants, the property address, the rental amount and due date, the security deposit amount, the lease term, and any rules and conditions of the tenancy. Leases must also include required California disclosure addenda — including the Megan's Law disclosure, lead paint disclosure for pre-1978 properties, and bedbug disclosure addendum.

2. Security Deposit Rules

As of July 1, 2024, California limits security deposits to one month's rent for most residential tenancies — regardless of whether the unit is furnished. The deposit must be returned within 21 days of the tenant vacating, with an itemized statement of any deductions. Deductions are limited to unpaid rent, cleaning to restore the unit to its original condition, and repair of damage beyond normal wear and tear. Failure to comply with security deposit rules exposes landlords to statutory penalties of up to twice the deposit amount.

3. Habitability Requirements

California Civil Code §1941 requires landlords to maintain rental properties in a habitable condition at all times. This includes functioning plumbing, heating, electrical systems, weatherproofing, and freedom from infestations. Habitability failures expose landlords to rent withholding, repair-and-deduct remedies, and civil liability. Local housing code enforcement can also result in notices of violation, administrative penalties, and orders to vacate.

4. Notice Requirements

California law requires specific written notice before entering a rental unit (generally 24 hours), before increasing rent (30 days for increases under 10%, 90 days for 10% or more), and before terminating a tenancy. All eviction notices must strictly comply with California Code of Civil Procedure requirements. Defective notices result in dismissed eviction cases.

5. AB 1482 Statewide Rent Control

California's Tenant Protection Act of 2019 (AB 1482) applies to most residential rental properties built before 2005 that are not covered by a stricter local rent control ordinance. It caps annual rent increases at 5% plus local CPI (maximum 10%) and requires just cause for eviction after a tenant has resided in the unit for 12 months. Single-family homes and condos may be exempt if proper written notice is provided to the tenant. Confirm whether AB 1482 applies to each of your units.

6. Local Rent Control Ordinances

Cities including Oakland, San Francisco, Berkeley, Los Angeles, San Jose, and many others have local rent control ordinances that are stricter than state law. These ordinances govern allowable rent increases, just cause eviction requirements, relocation assistance obligations, and notice content requirements. If your property is in a rent-controlled city, local ordinance governs — not just state law.
