Each Durham municipality’s official plan sets long-term land-use policy: where growth goes, density and intensification targets, employment areas, natural heritage systems, and infrastructure. Durham Region’s Official Plan adds the regional layer — growth forecasts, regional corridors, agricultural systems and natural heritage across the region. Zoning by-laws must conform to official plans, so when a proposal does not conform, an official plan amendment is needed alongside (or before) rezoning. Official plans are reviewed on a cycle to stay consistent with provincial policy. Read the official plan first for the big picture — it explains why an area is designated the way it is — then drill into the zoning details. Verify requirements with the municipality before applying or building.
