What Fredericton publishes for additional units
Fredericton’s current secondary-dwelling-unit page covers basement, accessory, garden and garage forms. The number of additional units that can be considered depends on the lot and municipal standards, and a building permit is required.

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.
New Brunswick Building Code Administration ↗Four questions before design
What kind of unit?
Detached garden or coach-house units add site-planning questions that an internal secondary suite may never trigger. Keep the Fredericton property and proposed unit form in view when applying that requirement.
Is the use allowed?
A general right to additional housing can still come with lot-specific limits. Check the address before treating the project as permitted.
Can the building comply?
Expect construction details such as egress, smoke/CO protection, ventilation and fire separation to influence the final layout.
Can the site serve it?
A legal unit also has to work on the site. Servicing, parking, access and detached-unit setbacks can affect feasibility.
A better Fredericton planning order
A good sequence is property eligibility, unit type, building design, utilities/trades and inspections. Starting with finishes can hide the expensive constraints.
For resale properties, the most useful evidence is the municipal file, not the number of years the unit has been rented.
