The Danbury Zoning Board of Appeals will be holding a hearing this week about Dorothy Day Hospitality House and their Spring Street facility.  There are several variances that will be discussed for grocery market, office space, emergency homeless shelter, and soup kitchen.  They include reducing the front, side and rear yard setbacks, reducing the driveway width, cutting down parking to 16 spaces, and reducing minimum square footage.  Waivers from certain zoning laws will be discussed.  The meeting Thursday is set for 7pm at Danbury City Hall in Council chambers.
