A security deposit is your money, not the landlord's — held only as security against unpaid rent and genuine damage. Yet deposit disputes are among the most common landlord-tenant conflicts, largely because tenants rarely know three things the law actually gives them: a cap on how much can be collected, a firm deadline for the money's return, and a real financial penalty when a landlord withholds it in bad faith. Knowing your state's numbers turns a vague 'I think they owe me' into a specific, enforceable claim.

How much can a landlord legally hold — and when caps changed
Colorado ordinary residential deposits are capped at two monthly rent payments. California possible bad-faith statutory damages are up to twice the total deposit, separate from actual damages and only if the court finds bad faith; lateness alone is insufficient. Florida uses 15 days for a no-claim return and 30 days for claim notice after tenancy termination, followed by separate objection and payment rules. Florida interest depends on the holding method, which may lawfully be non-interest-bearing.

Deductions: what a landlord can and cannot keep

A landlord may deduct only two things: unpaid rent you actually owe, and the cost of repairing damage beyond normal wear and tear. The wear-and-tear line is where most disputes live. Faded paint, worn carpet in traffic paths, minor scuffs, and small nail holes are normal wear and cannot be charged in any state. A cracked tile, a pet-stained carpet, a hole punched in drywall, or a unit left filthy are damage and can be. Most states require the landlord to back every deduction with a written, itemized statement — and often receipts — within the return deadline. A landlord who skips the itemized statement frequently forfeits the right to withhold anything, even for real damage. Photograph every room at move-out, keep your move-in condition report, and put your forwarding address in writing so the clock starts.
