What Charlottetown publishes for additional units
Charlottetown maintains a registry and approval route specifically for secondary and garden suites. Applicants need to use the city’s current zoning, registration and permit material rather than treating an existing unit as automatically recognized.

Prince Edward Island: the provincial layer
PEI generally requires both development and building permits for residential construction. The development permit addresses land use and siting; the building permit addresses code compliance.

The Charlottetown link is topic-specific, so it is the strongest local starting point for this page rather than a generic city homepage. The verified local material specifically points toward detached/garden-unit rules.
For Charlottetown, the current source summary is therefore most useful for checking detached/garden-unit rules. Do not substitute a neighbouring municipality’s numeric rule for anything the local source leaves open.
