In Practice
A security deposit is a refundable sum collected before move-in. It protects the owner if a resident leaves unpaid rent, unpaid fees or damage beyond normal wear and tear. It is not a last month's rent payment unless your lease and state law say so.
Day to day, you collect it at lease signing, post it to the resident ledger, and hold it as your state requires. Some states cap the amount, require a separate account, or require interest. At move-out you inspect, compare against the move-in photos, and send an itemized list of deductions with any refund inside the legal deadline.
Example: a resident leaves a stained carpet and a missing blind. You document both, price the repair with receipts, deduct only those costs, and return the rest on time. Painting a unit that was due for paint anyway is not a fair deduction.
The common mistake is missing the return deadline or skipping the itemized list. In many states that can cost the owner the right to keep any of the deposit, and sometimes more. Rules vary by state and city, so check local law or ask counsel.
Not to Be Confused With
A security deposit covers any damage or unpaid balance. A pet deposit is collected only for pet-related damage and may be restricted by state law.
Security Deposit: Common Questions
How much can a landlord charge for a security deposit?
It depends on your state and sometimes your city. Some states cap it at one or two months of rent and others set no limit, so check local law.
How long does a landlord have to return a security deposit?
State law sets the deadline, often somewhere between 14 and 60 days after move-out, and many states require an itemized list of deductions. Confirm your local rule.
Security deposit vs pet deposit: what is the difference?
A security deposit covers general damage and unpaid charges. A pet deposit is a separate amount held for pet-related damage, where your state allows one.
