Castle Rock has no separate STR registration. Operators register the same way any business does — by obtaining a Town of Castle Rock sales-tax/business license before collecting lodging and sales tax.
Because the Town does not regulate short-term rentals as a land use, there is no STR registry, no annual STR renewal, and no dedicated STR application. Registration happens through the Town's Revenue Division sales-tax licensing system (the Town's online sales-tax portal at castlerocktax.my.site.com). Once licensed, the operator files returns and remits the 6% lodging tax plus Town sales tax. Property in unincorporated Douglas County, not the Town, follows the County's separate STR license process instead.
Collecting rent without a Town sales-tax/business license means unlicensed operation; the Revenue Division can pursue back tax, penalties and interest.
