In Colorado, if your landlord gave you verbal and written confirmation that you would receive your security deposit back after a walk-through, they generally cannot keep it unless there is a valid legal reason. According to Colorado security deposit laws, a landlord is required to return the deposit within one month (or up to 60 days if allowed by the lease). If they choose to withhold any portion of the deposit, they must provide an itemized statement explaining why.
If your landlord fails to return the deposit or provide this itemized statement within the required time frame, they forfeit their right to retain any portion of the deposit and may be liable for damages, including up to three times the deposit amount and attorney’s fees.
Since you have written confirmation, the landlord would likely be in violation of these regulations if they do not follow through. You may be able to recover the deposit and pursue additional legal remedies if necessary.
