Use Dieppe’s current secondary-suite checklist route

Dieppe’s current planning and construction guides specifically include a secondary-suite checklist. Use that municipal route to confirm the property, unit form and documents required before construction.

Southern New Brunswick is useful market context, but another municipality’s suite approval does not transfer to Dieppe. Check this property directly.

New Brunswick: the provincial layer

New Brunswick administers the National Building Code through provincial legislation and local/regional permitting. A suite project still needs the local land-use and building-permit route checked.

What the Dieppe source actually tells you

The Dieppe source is primarily a permit route. It is useful for application and inspection steps, but zoning permission still has to be confirmed for the property. The verified local material specifically points toward zoning.

For Dieppe, the current source summary is therefore most useful for checking zoning. Do not substitute a neighbouring municipality’s numeric rule for anything the local source leaves open.

Source evidence: the current local route was directly inspected in the 2026-09-18 external-source audit. Rules can change after that review date.

Next planning steps

Confirm local zoning before you estimate project costs.

This guide explains the municipal process, not whether your specific property is approved. The next two steps are budgeting and contractor scoping; neither replaces municipal approval.
