August 22, 2025

As a landlord in California, it’s important to understand your rights and responsibilities regarding security deposits. At BanCal Properties, we work with property owners to help them stay compliant with state and local regulations.


Security deposits protect landlords from negligent tenant actions, such as unpaid rent, significant property damage, or severe uncleanliness. However, state law places important restrictions on how these deposits can be collected, managed, and returned.

Maximum Security Deposit Limit


California landlords must comply with strict rules on deposit amounts. State landlord-tenant law limits the standard deposit to the equivalent of one month’s rent.


There are exceptions, though. You may charge up to two times the monthly rent if all the following conditions are met:


  • You own only one other residential property with four or fewer rental units.
  • You are the sole owner of the rental properties, or you own them with others through an LLC.
  • You are not a member of the armed forces.


Another exception applies if you are renting to a tenant with a waterbed. In this case, you may charge up to 1.5 times the monthly rent, plus a reasonable administrative fee.


Additional Pet Deposit


Landlords may charge a pet deposit as long as the total amount does not exceed the state’s security deposit limit. However, tenants with service animals or emotional support animals cannot be charged extra.

Under California fair housing laws, disability is a protected class, and landlords must make reasonable accommodations, such as:


  • Providing accessible parking spaces.
  • Adjusting rent due dates to align with disability-related income schedules.
  • Allowing a live-in caregiver or family member.

Security Deposit Holdings


Unlike some states, California does not require landlords to hold security deposits in special accounts.


However, certain cities, such as Santa Cruz and Berkeley, mandate that deposits be stored in interest-bearing accounts, with interest paid to tenants. Landlords should always check local laws for additional requirements.


Sale of Rental Property


When a rental property is sold, the landlord must do one of two things:


  1. Transfer the tenant’s deposit, minus allowable deductions, to the new landlord. The new landlord then assumes responsibility.
  2. Refund the deposit directly to the tenant, minus allowable deductions.

In both cases, the outgoing landlord must provide the incoming landlord with a written statement detailing:


  • The deposit amount after deductions.
  • An itemized list of deductions.
  • Whether the remaining deposit was transferred or refunded.


Security Deposit Deductions


Landlords may deduct from a tenant’s security deposit for the following reasons:


  • Unpaid rent.
  • Repairs for negligent or careless property damage.
  • Professional cleaning costs.
  • Restoration costs outlined in the lease.


There is no legal limit on deduction amounts, but they must always be reasonable.


Normal Wear and Tear vs. Damage


Normal wear and tear refers to the natural aging of a rental unit and is the landlord’s responsibility to address. Examples include: lightly scratched glass, stained bath fixtures, slightly dirtied grout, or gently worn carpets.

Damage caused by tenant negligence, however, can be deducted from the deposit. Examples include missing fixtures, large holes in walls, broken locks, or damaged flooring.


Security Deposit Returns


California law requires landlords to return security deposits within 21 days after a tenant vacates. If deductions are made, the landlord must provide an itemized list to the tenant.
