Carmel's required yards (setbacks) are set per zoning district in the UDO's Article 2 two-page layouts, not by one citywide number. For example, the S1 district requires a 40-foot front yard; S2 and R1 require 35 feet; side and rear yards range from 10 to 20 feet for single-family homes.

Except as otherwise provided for Corner and Through Lots, when detached from the Principal Building, Accessory Buildings shall be set back a minimum of the greater of the following: twenty-five (25) feet behind the Front Line of Principal Building; twenty-five (25) feet behind the Principal Building Setback Line.
