Frequently Asked Questions
How much does it cost to build a garage in New Brunswick?
Garage construction costs in NB vary by type and size. A basic single-car detached garage (12x24 feet) runs $25,000-$45,000, while a double-car detached garage (24x24 feet) costs $40,000-$75,000. Attached garage additions range from $35,000-$90,000. Heated garages with full insulation and climate control add $8,000-$20,000 to the base cost. NB-specific factors include frost depth foundation requirements, regional snow load ratings, and seasonal construction windows that favour May through October for foundation work.
Do I need a building permit for a garage in New Brunswick?
Yes, virtually all garage construction in NB requires a building permit. Any structure with a footprint exceeding 10 square metres (108 square feet) requires a permit from your local municipality. You will need site plans showing setbacks from property lines, foundation plans meeting frost depth requirements, and structural drawings. Attached garages also require fire separation details including fire-rated drywall and self-closing doors. Permit fees typically run $200-$800 based on project value.
Should I build an attached or detached garage?
Attached garages offer direct house access during NB's harsh winters and share a wall with the home, reducing construction costs by 15-25%. However, they require fire-rated separation and careful vapour management. Detached garages offer more flexibility in size and placement, eliminate fire separation concerns, and are ideal for workshops where noise and dust separation from the house is desirable. Your lot layout, budget, and intended use should drive the decision.
What garage foundation type works best in New Brunswick?
A concrete slab with thickened edges works for unheated detached garages on well-drained soil, costing $4,000-$10,000. Frost wall foundations extending below the frost line (1.2 metres in southern NB, up to 1.5 metres in northern regions) are required for heated garages and attached additions, costing $8,000-$18,000. In areas with high water tables along the Saint John and Petitcodiac rivers, additional drainage and waterproofing measures are essential.
