A SDAB hears appeals regarding decisions made by a municipality’s subdivision and development authorities. Its decisions are based on the evidence presented to it during a public hearing and is a separate body of community residents that is established to ensure land use bylaws are being applied fairly and in a way that is consistent with the local community.  Briefly, the function of a SDAB is to provide a mechanism for interested parties to challenge: 

A decision of a development authority on a development application;
A decision of a subdivision authority on a subdivision application

where the Provincial Board does not have jurisdiction; 

The issuance of a stop order;

and
If an interested /impacted person disagrees with a decision on a development application, a decision on certain subdivision applications or the issuance of a stop order, he or she may also file an appeal in some circumstances.
