Colorado Security Deposit Rules: Limits & Deadlines
Colorado landlords: Understand security deposit limits, return deadlines, and documentation requirements. Avoid claims with proper record-keeping.

Colorado's security deposit laws protect both landlords and tenants, ensuring fair handling of deposits. As a landlord, understanding these regulations is crucial to avoid legal issues and maintain positive tenant relationships.
Security Deposit Caps in Colorado
Colorado law sets specific limits on security deposits:
- Unfurnished units: Maximum of one month's rent
- Furnished units: Up to 1.5 months' rent
Example: For a $2,000/month unfurnished unit, the maximum deposit is $2,000. A furnished unit at the same rent allows up to $3,000.
Key Points:
- These caps apply to both new and renewed leases
- Additional non-refundable fees (like pet fees) must be clearly itemized and separate from the security deposit
- Always specify in the lease whether the unit is furnished or unfurnished
Pro Tip: Use TenantFlow to track lease types and rental amounts, ensuring you never exceed legal deposit limits.

Colorado requires landlords to return security deposits within:
- 1 month of lease termination (default)
- 60 days if specified in the lease agreement
Example Timeline:
- Lease ends: August 31

- Itemized deductions sent to tenant: September 15 (for standard 1-month window)
- Remaining deposit returned: September 20
Critical Steps:
- Schedule move-out inspection promptly after lease end
