Use Southern New Brunswick only as location context. Height, visibility and enclosure rules still need the current Fredericton source.
The four fence checks that change the answer
Front, side or rear?
Frontage and flanking-street conditions can use different limits from the private side or back of a lot.
Corner or driveway?
Corner lots often have an extra visibility layer, so the normal maximum is not the only number that matters.
Pool or hot tub?
Water-safety enclosures can add minimum heights and gate controls, so a standard fence design may need changes.
Retaining wall?
Where the yard steps up or down, ask how height is measured at the fence line instead of assuming level-ground rules.
Put the Fredericton rule against the actual property
A simple site sketch can prevent the most common mistake: applying one height limit to every edge of the property.
The municipality can regulate the fence without adjudicating a neighbour dispute, so verify the line separately when it is uncertain.
Do not assume a privacy fence doubles as a pool barrier. Water-safety provisions often add their own minimums and gate controls.
