As of January 1, 2024, all rental properties in Denver County, including single-family homes, must have a rental license. This requires passing an inspection by a third-party inspector and submitting the report along with other disclosures to the county. The rental license number must also be included in all advertisements. The county is enforcing this rule strictly, even encouraging tenants to report unlicensed properties. Landlords should apply as soon as possible to avoid penalties. Bergen & Company handles this process for its clients, ensuring compliance and streamlining the application.
