To move forward with a Department of Buildings job on a tax lot that has an E-Designation, also known as a "little E," you must get an approval letter from the Mayor's Office of Environmental Remediation.

An "E-Designation" is the identification on the City's zoning map of a tax lot that might be negatively impacted by:

  • Hazardous materials contamination 
  • High noise levels
  • Poor air quality
