The Brenton Building, located at 1136 Alpine Avenue, will be closed to the public until further notice. However, staff will be working between the hours of 8am and 5pm Monday through Friday and will continue to respond to voicemails and emails in the order in which they are received.

City Regulatory Licensing Applicants or Licensees:

The reason that you are receiving this email or viewing this content on our website is that the City of Boulder has determined an office closure due to the COVID19 virus. Please also share this information with your attorney of record or accountant if you have one.
Due to this, City Licensing Staff will be continuing our licensing work, but we will be working remotely and will not be physically available to meet with you in our Brenton Building offices. In addition, we will not be individually meeting with customers to review applications or be conducting our application clinics in person during this time. We will individually correspond with you about board hearings, board meetings, postings, and premise inspections.

For phone calls, our direct city phones and prompts for our main number of 303-441-4192 will include a message that email is the best way to reach us.  However, if a customer leaves a voice mail it may take several days to return calls via this means of communication, so emails are fastest and best.

Some license application types are now being filed through our online CSS web portal. Contact Licensing Staff to see if your application type is availlable for online services.

We recognize that some of our larger applications, such as new license applications, will be large files so if you submit such an application, please include in your subject line (Trade name, License Type and file x of xx) so that we can easily match those multiple scanned files.  Please also see below request for payment instructions for online payments or mailing instructions and pictures to be  included with emailed filings.

If you are unable to submit  applications via our online CSS web portal or by scanned email and by one pf the payment options above, please contact City Licensing at [email protected] to make alternate arrangements.

For state liquor fee payments for scanned and emailed New, Transfer and Change of Class liquor license applications: Licensing staff will require that you mail state fee checks directly to the State Liquor Enforcement Division at:
