A Subdivision and Development Appeal Board (SDAB) is a quasi-judicial tribunal that hears appeals of subdivision and development permit decisions made by municipal planning departments. SDABs provide an appeal mechanism for applicants and affected parties who disagree with administrative decisions, without requiring expensive court proceedings. Board members are typically citizen appointees with relevant knowledge or expertise. SDABs hold public hearings, consider evidence from appellants and the municipality, and render decisions that can confirm, reverse, or modify original decisions. SDAB decisions must be based on planning legislation and municipal bylaws, not personal preferences. Appeals of SDAB decisions may proceed to courts on questions of law or jurisdiction, not planning merits.
