The Danbury Department of Health & Human Services has created a confidential reporting form for residents to fill out online if they have any concerns about how businesses are operating during the COVID-19 crisis.  City officials say the health department can follow up appropriately and ensure proper protocols are followed.

The State also created a Business Complaint Form.  The state form is more comprehensive and is intended for complaints that pertain to requirements of the Sector Rules only.

On the City report form, in addition to basic information about the business, complainants are asked whether the business should not be open, is allowing food self-service, is allowing dine-in service above capacity, or a blank to explain another reason.
