Why do I need a COA for alterations to a non-historic, contemporary building?

Alterations to one building can affect nearby properties.  Therefore, proposed alterations are evaluated for compliance with the ordinance guidelines to determine if there will be any detrimental impact on adjacent properties.  Alterations should be compatible with and maintain the existing contemporary style.  The Historic Preservation Commission is required to apply the “maximum flexibility” allowed by the ordinance in its review of applications for structures that have little historic or architectural significance.
