How much do contractors charge for suite separate entrance in New Brunswick?

Creating a separate entrance for a secondary suite typically costs $8,000-$25,000 in New Brunswick, depending on whether you're adding an exterior door to an existing opening or cutting through foundation walls and adding stairs.

Cost Breakdown by Scope

Basic door installation (existing rough opening): $2,500-$5,000 including a quality exterior door, weatherstripping, trim work, and basic landing/steps. This assumes the framing and foundation work is already complete.

Full exterior entrance creation ranges $12,000-$25,000+ and includes:

• Foundation cutting and reinforcement: $3,000-$6,000


• Framing and structural work: $2,000-$4,000


• Concrete steps or wooden deck: $2,500-$8,000


• Door installation and finishing: $2,500-$4,000


• Electrical for exterior lighting: $800-$1,500


• Permits and inspections: $300-$800

Walkout basement conversions are often the most cost-effective option when possible, running $8,000-$15,000 since you're working with existing grade rather than excavating.

New Brunswick Code Requirements

The National Building Code 2020 (effective May 1, 2025 for new applications) requires secondary suite entrances to provide direct access to the outside without passing through the primary dwelling. The entrance must have minimum 32-inch clear width and proper weather protection.

You'll need a building permit from your municipality (in cities like Moncton, Saint John, Fredericton) or your Regional Service Commission if you're in a rural area. The structural work requires inspection, and any electrical work needs a licensed electrician with an NB Power wiring permit (1-800-615-0522).

Foundation work is particularly important in New Brunswick's climate - any new openings must maintain structural integrity and account for our 4+ foot frost line. Proper drainage around new entrances prevents the basement moisture issues common in our clay soils.

Zoning Compliance First

Before getting quotes, verify your property allows secondary suites through your municipal zoning office or RSC planning department. Each community has different rules - what's permitted in Dieppe may not be allowed in rural Kings County. This step prevents costly surprises mid-project.

Contact licensed contractors through our New Brunswick Construction Network directory for detailed quotes based on your specific foundation type, soil conditions, and municipal requirements.
