California Landlord Laws: A Practical Guide for 2026

Introduction

California rental law in 2026 sits on top of three load-bearing statutes: the Tenant Protection Act of 2019 (AB 1482), the security deposit overhaul in AB 12 (effective July 2024), and the long-standing landlord-tenant chapter of the Civil Code (§§1940–1954). Add local rent control ordinances in cities like Los Angeles, San Francisco, Oakland, and Berkeley, and the rules vary noticeably by ZIP code. This guide gives a landlord-side walkthrough of the statewide minimums every owner has to meet, plus a few of the California-specific traps that quietly create the most disputes.

Security Deposits

Cap. Since July 1, 2024, AB 12 caps the security deposit at one month's rent for most California rentals, furnished or unfurnished. Owners who qualify as “small landlords” — natural persons (or LLCs whose members are all natural persons) who own no more than two residential properties totaling no more than four units — may charge up to two months' rent. Service members are always limited to one month's rent regardless of furnishing.

Return window. Civil Code §1950.5 gives you 21 calendar days after the tenant vacates to either return the deposit in full or send an itemized statement of deductions with the unused balance. If deductions exceed $125, you must include receipts or invoices.

Permitted deductions. Unpaid rent, repair of damage beyond ordinary wear and tear, and (if your lease says so) reasonable cleaning to return the unit to its move-in level of cleanliness. Painting a unit after a long tenancy or replacing end-of-life carpet generally falls under wear and tear, not the deposit.

Penalty. Missing the 21-day deadline or making bad-faith deductions can expose you to up to twice the deposit in statutory penalties on top of actual damages. Time-stamped move-in/move-out photos and a written walkthrough checklist are the single best protection you can build.

How Landlord Co-Pilot helps: the move-in/move-out inspection flow stores photographed condition reports against the lease so deductions are defensible, and the tenant ledger surfaces unpaid rent that legitimately offsets the deposit.

AB 1482 — Statewide Rent Cap

Cap. For covered units, you may not raise rent by more than 5% plus the regional CPI in any 12-month period, with a hard ceiling of 10%, and no more than two increases per year. The California Attorney General's office publishes the applicable CPI by region each year — check before issuing a notice.

Coverage. AB 1482 covers most apartment buildings statewide. The main exemptions are (1) single-family homes and condominiums where the owner is a natural person (not a corporation, REIT, or corporate-member LLC) and the tenant has received the statutory written exemption notice, (2) buildings issued a certificate of occupancy within the last 15 years (a rolling window, so a building exempt this year may become covered later), and (3) deed-restricted affordable units. Stricter local rent control supersedes AB 1482 for units it covers.

Notice format. A standard rent increase requires 30 days' written notice if the increase is 10% or less of the lowest amount charged in the prior 12 months; larger increases require 90 days' notice (though for covered units the cap itself usually keeps you in the 30-day window).

How Landlord Co-Pilot helps: the lease record stores effective dates and previous rent, so you can check at a glance whether a proposed increase falls inside the AB 1482 ceiling before you send the notice.

Just-Cause Eviction

On the same units that AB 1482's rent cap covers, you also need just cause to terminate a tenancy once the tenant has occupied the unit for 12 continuous months (or 24 months if any adult tenant has been there less than a year). The statute splits causes into two categories.

At-fault just cause includes nonpayment of rent, material lease breach, nuisance, criminal activity on the premises, refusal to renew a similar lease, refusing lawful entry, and a few other tenant-side reasons. You serve the appropriate notice (3 days to pay or quit, 3 days to cure or quit, etc.) before filing an unlawful detainer.

No-fault just cause includes owner or close-relative move-in, withdrawal of the unit from the rental market (the Ellis Act in rent-controlled jurisdictions has its own additional rules), compliance with a government order, and substantial remodel. For any no-fault termination you must either pay the tenant one month's rent in relocation assistance or waive the final month's rent in writing.

Notice Requirements

Entry

Civil Code §1954 requires reasonable written notice — presumed reasonable at 24 hours — before entering for repairs, inspections, agreed services, or showings. The notice must include the date, approximate time, and purpose. Entries are limited to normal business hours unless the tenant agrees otherwise. Emergencies and abandonments are the only exceptions.

Terminating tenancy

For month-to-month tenancies outside AB 1482, the default termination notice is 30 days if the tenant has lived there less than a year, and 60 days if a year or more. Covered units require just cause as described above. A 3-day notice to pay or quit triggers an unlawful detainer if not cured; California excludes Saturdays, Sundays, and judicial holidays from that 3-day count.

Habitability

Every California residential lease carries an implied warranty of habitability — you cannot waive it. The unit must, at minimum, have effective waterproofing, plumbing and gas in good working order, hot and cold running water, heat, electrical in good condition, sanitary common areas, working trash receptacles, working smoke and carbon monoxide detectors, and structural integrity (Civil Code §1941.1; Health & Safety Code §17920.3).

If you ignore a written habitability complaint, the tenant may have a right to repair and deduct (capped at one month's rent, twice per year), withhold rent, or sue. California also prohibits retaliation against tenants who exercise these rights for at least 180 days after their complaint.

Rental Application Fees

Civil Code §1950.6 caps the screening fee a landlord may charge a prospective tenant at a CPI-indexed amount — the statutory cap was set at $30 in 1998 and is recalculated each year against the regional CPI. Industry reports place the cap at roughly $59.67 as of 2026, but the precise figure changes annually; always confirm the current cap before charging. You can only charge for the actual out-of-pocket cost of obtaining a credit report plus a reasonable hourly cost for processing the application, never more than the cap. You must also provide a copy of the credit report to the applicant on request.

Required Disclosures

California layers a long list of disclosures on top of the federal lead-based paint rule for pre-1978 properties. Every California lease should include:

• Federal lead-based paint disclosure (24 CFR §35) — pre-1978 properties, with EPA pamphlet
• Megan's Law database notice (Civil Code §2079.10a) — statutory boilerplate text
• Mold disclosure (Health & Safety Code §26147) — if you know of a mold condition that exceeds permissible exposure limits
• Bedbug history disclosure (Civil Code §1954.603) — including any history at the property
• Flood hazard disclosure (Government Code §8589.45, AB 1857) — if the unit lies in a special flood hazard area
• Demolition permits applied for in the next 12 months
• Death-on-the-premises disclosure — within the last 3 years (Civil Code §1710.2), except HIV/AIDS-related
• Smoke detector and carbon monoxide alarm installation
• Gas and transmission pipeline notice (Civil Code §1102.6f) — for newer leases in covered areas
• Pest control disclosure (Civil Code §1940.8) — if a periodic pest control service is in place
• Domestic violence immunity (Civil Code §1161.3) — boilerplate that protects survivors from eviction

A clean, state-specific lease template that bundles these disclosures into the signing flow is the easiest way to avoid omissions. The lease management workflow inside Landlord Co-Pilot stores the signed copy alongside the tenant ledger so the disclosure paper trail is intact at renewal and at move-out.

Common California-Specific Traps

• Charging the old 2-month deposit on a non-small-landlord lease post-AB 12
• Skipping the AB 1482 exemption notice on a single-family home and losing the exemption by default
• Issuing a no-fault eviction without paying the one-month relocation assistance
• Entering for showings during the last 30 days of tenancy without 24-hour written notice
• Forgetting that local rent control (e.g., LA, SF, Oakland, Berkeley) is often stricter than AB 1482
• Missing the 21-day deposit return deadline because the keys were returned later than the move-out date
• Using a generic lease that omits Megan's Law, bedbug, or flood disclosures
