Documents have been added to the case file of the City of Danbury Zoning Board of Appeals versus Dorothy Day Hospitality House.   A clerk for the Board sent documents to the court about the decision to deny exemptions from certain zoning regulations so that the owner of the Spring Street facility could get a special permit from the Planning Commission to operate as a soup kitchen.  Dorothy Day hasn't held a permit for more than three decades.  City officials recently learned that the owners never applied for a renewal after the initial special permit was granted.  The documents include dozens of letters in favor of Dorothy Day, with the opposition letters coming from nearby businesses and the Zoning Enforcement Officer.  The documents span from early 2016 through the legal decision that September.
