California's landlord-tenant relationship is governed by the California Civil Code Sections 1940-1954.06, along with several landmark pieces of legislation including AB 1482 (the Tenant Protection Act of 2019) and AB 12 (effective July 1, 2024). California is widely considered the most tenant-protective state in the nation. Here's everything you need to know.

Security deposits in California

Key details:

• AB 12 (effective July 1, 2024) reduced the maximum security deposit from 2 months' rent (unfurnished) or 3 months' rent (furnished) to 1 month's rent for all residential tenancies, regardless of furnished or unfurnished status (CA Civil Code 1950.5)
• Small landlords with 1-2 units who are natural persons (not LLCs or corporations) received a temporary exemption allowing up to 2 months' rent through June 30, 2025. As of July 1, 2025, the 1-month cap applies to all landlords
• The landlord must return the deposit or provide an itemized statement of deductions within 21 calendar days after the tenant vacates (CA Civil Code 1950.5(g))
• The itemized statement must describe each item of damage, the repair cost, and include copies of receipts for completed repairs. For repairs not yet completed, a good-faith estimate is acceptable, but the landlord must provide final receipts within 14 days of completion
• If repairs will take longer than 21 days, the landlord must send the itemized statement within 21 days with good-faith estimates, then a final accounting within 14 days of completion
• Last month's rent cannot be used as a security deposit — it must be a separate charge within the 1-month cap
• Nonrefundable deposits or fees are prohibited in California (CA Civil Code 1950.5(m)). The only exception is a legitimate, reasonable screening fee
• The tenant has the right to request an initial inspection before move-out to identify potential deductions and have the opportunity to correct them (CA Civil Code 1950.5(f))
• If the landlord fails to comply with the deposit return requirements, the tenant may recover up to 2 times the deposit amount in addition to actual damages, plus attorney's fees in bad faith cases

Eviction process in California

California eviction (called unlawful detainer) follows a strict legal process governed by CA Code of Civil Procedure Sections 1161-1179a. Self-help evictions are illegal and can result in significant damages to the landlord.

Just cause eviction (AB 1482)

Since January 1, 2020, most California tenants are protected by just cause eviction requirements under AB 1482 (CA Civil Code 1946.2). This applies to tenants who have occupied the unit for 12 months or more (or all tenants in properties built before 2005 in many local jurisdictions).

At-fault just cause includes:

• Nonpayment of rent
• Breach of a material lease term
• Nuisance or criminal activity
• Refusal to execute a substantially similar lease renewal
• Refusal to allow the landlord lawful access
• Subletting in violation of the lease

No-fault just cause includes:

• Owner or immediate family member move-in
• Withdrawal from the rental market (Ellis Act)
• Substantial remodel requiring vacancy
• Compliance with government or court order
• Intent to demolish

For no-fault evictions, the landlord must provide relocation assistance equal to one month's rent, either as a direct payment or rent waiver (CA Civil Code 1946.2(d)).

Step 1: Serve proper notice

Important notice rules:

• The 3-day notice to pay or quit must state the exact amount of rent owed and cannot include late fees, utilities, or other charges (only rent). It must also include the name, address, and phone number of the person authorized to receive payment, and it must offer at least one form of payment that is cash, check, or electronic funds transfer
• California law requires that notices be served by personal delivery, substituted service (leaving with someone at the home + mailing), or posting and mailing (only if the other methods fail)
• Under local ordinances in cities like San Francisco, Los Angeles, Oakland, Berkeley, and others, additional just cause requirements and tenant protections may apply beyond AB 1482

Step 2: File an unlawful detainer

If the tenant does not comply with the notice, file an unlawful detainer complaint in Superior Court. Filing fees range from approximately $240 to $435 depending on the amount claimed.

Step 3: Tenant's response

The tenant has 5 calendar days to respond (answer) to the complaint. If the tenant does not respond, you can request a default judgment.

Step 4: Trial

If the tenant answers, the case goes to trial. Unlawful detainer cases are given priority on the court calendar and are typically set for trial within 20 days of the request.

Step 5: Writ of possession

If the court rules in your favor, the clerk issues a writ of possession. The sheriff or marshal posts a 5-day notice to vacate. If the tenant does not leave, the sheriff will conduct a lockout.

Total timeline: Uncontested cases can be resolved in 3-5 weeks. Contested cases typically take 5-8 weeks. Complex cases with jury trials can take several months.

Late fees in California

Key details:

• California law does not specify a dollar amount or percentage cap on late fees. However, late fees must be a "reasonable estimate of the costs incurred by the landlord" as a result of late payment (CA Civil Code 1671)
• Late fees that are disproportionate to the landlord's actual costs are considered liquidated damages penalties and are void and unenforceable
• California courts have generally found late fees of 5-6% of monthly rent to be reasonable. A $75 late fee on $1,500 rent (5%) is typical. Fees above 10% are at significant risk of being struck down
• There is no statewide mandatory grace period, but several local ordinances (Los Angeles, San Francisco, and others) require grace periods, typically 5 days
• The late fee must be stated in the written lease agreement
• Compounding or escalating late fees (daily fees that accumulate) are generally disfavored by California courts. If you charge daily fees, keep the total reasonable
• During declared states of emergency, additional restrictions on late fees may apply (as seen during COVID-19 protections)

Lease requirements in California

California requires a written lease for tenancies longer than one year (Statute of Frauds, CA Civil Code 1624). However, written leases are strongly recommended for all tenancies.

Required lease provisions and disclosures

California has the most extensive disclosure requirements of any state. The following must be provided at or before lease signing:

1. Lead-based paint disclosure — properties built before 1978 (federal, 42 U.S.C. 4852d)
2. Mold disclosure — landlord must provide information about mold to tenants (CA Health and Safety Code 26147-26148)
3. Bed bug disclosure — landlord must provide information about bed bugs, including their behavior, biology, and prevention (CA Civil Code 1954.603, effective 2016)
4. Pest control disclosure — if the landlord has used pest control, the tenant must receive disclosure of the company name, pesticides used, and any precautions (CA Civil Code 1940.8)
5. Demolition disclosure — if the landlord has applied for a permit to demolish the unit (CA Civil Code 1940.6)
6. Death disclosure — if a death occurred on the property within the last 3 years (CA Civil Code 1710.2). Note: deaths from AIDS/HIV need not be disclosed
7. Sex offender database (Megan's Law) — every lease must include a notice that information about registered sex offenders is available from law enforcement (CA Civil Code 2079.10a)
8. Flood zone disclosure — if the property is in a special flood hazard area (CA Government Code 8589.45)
9. Fire hazard zone disclosure — if the property is in a fire hazard severity zone (CA Government Code 51183.5)
10. Military ordnance location — if the property is in a known former military ordnance area (CA Civil Code 1940.7)
11. Industrial use disclosure — if the property is within one mile of a former military ordnance location or known environmental hazard
12. Toxic mold — specific information about toxic mold provided by the Department of Health (CA Health and Safety Code 26148)
13. Smoking policy — the landlord must disclose the smoking policy for the property (CA Civil Code 1947.5)
14. Intent to sell — if the landlord intends to sell the property within the next year (CA Civil Code 1946.2(e) — related to AB 1482 protections)
15. AB 1482 applicability notice — landlords must notify tenants in writing if the property is or is not subject to AB 1482 rent caps and just cause protections (CA Civil Code 1946.2(f))
16. Notice of tenant rights — a document summarizing tenant rights must be provided (various local ordinances)
17. Utility arrangements — disclosure if the tenant pays for shared utilities or for another unit's utilities (CA Civil Code 1940.9)

Maintenance and repairs in California

Landlord obligations (CA Civil Code 1941-1942.5)

California imposes a strong implied warranty of habitability. Landlords must:

• Maintain the property in a condition fit for human occupation

Tenant remedies for repair failures

California provides tenants with strong remedies:

1. Repair and deduct — the tenant may make repairs and deduct the cost from rent, up to one month's rent per repair, up to twice per 12-month period (CA Civil Code 1942)
2. Rent withholding — the tenant may withhold rent if the landlord fails to maintain habitable conditions. This is a court-created remedy (Green v. Superior Court, 1974)
3. Rent escrow — the tenant deposits rent with the court while habitability issues are resolved
4. Lease termination — the tenant may vacate and terminate the lease if the unit is uninhabitable (CA Civil Code 1942)
5. Civil lawsuit — the tenant may sue for damages, including rent reduction, property damage, medical expenses, and emotional distress
6. Code enforcement — the tenant may contact local building or health inspectors

Tenant obligations

Tenants must:

• Keep the dwelling clean and sanitary
• Dispose of garbage properly
• Use all systems and appliances reasonably
• Not damage the property willfully or through negligence
• Not permit guests to damage the property

Rent increase rules in California

Rule	California Law
Statewide rent cap (AB 1482)	5% + local CPI (max 10%) per year
Notice required (under 10%)	30 days written notice
Notice required (10% or more)	90 days written notice
Local rent control	Active in many cities (see below)
Mid-lease increases	Not permitted unless lease contains escalation clause
Retaliatory increases	Prohibited (CA Civil Code 1942.5)

AB 1482 — Tenant Protection Act (statewide rent cap):

• Applies to most residential properties in California that are 15 years old or older
• Limits annual rent increases to 5% plus the local Consumer Price Index (CPI), with a hard cap of 10% regardless of CPI
• Exemptions include: single-family homes (if the owner is not a corporation, REIT, or LLC with a corporate member, and the owner provides written notice of exemption), new construction (first 15 years), owner-occupied duplexes, ADUs where the owner occupies the primary unit
• The landlord must provide written notice of AB 1482 exemption to claim it
• AB 1482 was originally set to expire in 2030 but political discussions about extension or permanence are ongoing

Local rent control ordinances:

Many California cities have their own rent control laws that are stricter than AB 1482:

City	Annual Rent Increase Cap	Key Notes
San Francisco	60% of CPI (typically 1-3%)	Applies to buildings built before June 1979
Los Angeles	3-8% (set annually by LAHD)	Applies to buildings built before October 1978
Oakland	CPI-based (typically 2-4%)	Applies to buildings built before January 1983
Berkeley	65% of CPI	Applies to buildings built before June 1980
San Jose	5% per year	Applies to buildings built before September 1979
Santa Monica	75% of CPI	Applies to buildings built before April 1979
West Hollywood	75% of CPI	Applies to buildings built before July 1979
Mountain View	CPI-based (max 5%)	Applies to buildings built before February 1995
Richmond	CPI-based	Applies to buildings built before February 2017
Hayward	5% per year	Applies to most multifamily buildings

Additional notes:

• If a property is subject to both AB 1482 and a local rent control ordinance, the stricter cap applies
• Rent increases must be served by written notice — 30 days for increases under 10%, 90 days for increases of 10% or more
• Rent increases cannot be retaliatory (CA Civil Code 1942.5) — a rebuttable presumption of retaliation exists if the increase occurs within 180 days of the tenant exercising a legal right
• Vacancy decontrol is standard — when a tenant voluntarily vacates or is evicted for cause, the landlord may reset the rent to market rate for the next tenant (Costa-Hawkins Rental Housing Act)

California has the most disclosure requirements of any state. Failure to make required disclosures can void certain lease provisions, expose the landlord to penalties, and provide tenants with defenses in eviction proceedings.

Tenant rights in California

Tenants in California have the right to:

• Habitable housing — the implied warranty of habitability is one of the strongest in the nation (CA Civil Code 1941)

• Rent cap protection (AB 1482) — annual rent increases limited to 5% + CPI (max 10%) for most tenancies
• Just cause eviction protection (AB 1482) — tenants who have lived in a unit for 12+ months cannot be evicted without just cause

• Repair and deduct — up to one month's rent, twice per year (CA Civil Code 1942)
• Rent withholding — for uninhabitable conditions
• Freedom from retaliation — landlord cannot increase rent, decrease services, or evict within 180 days of tenant exercising legal rights (CA Civil Code 1942.5)
