Are there NB accessibility code requirements for flooring transitions and thresholds in barrier-free home renovations?

Yes, New Brunswick follows the National Building Code accessibility requirements for barrier-free design, which include specific flooring transition and threshold standards. These requirements apply to new construction and renovations where barrier-free accessibility is being added or improved.

Key Accessibility Requirements for Flooring

Maximum threshold heights are strictly regulated in barrier-free design. Transitions between different floor surfaces cannot exceed 13mm (1/2 inch) in height, and any transition over 6mm (1/4 inch) must be beveled at a maximum 1:2 slope. This means if you're transitioning from hardwood to tile and there's a 10mm height difference, you need a beveled transition strip that slopes gradually rather than creating a sharp edge.

Smooth transitions are required at doorways and between rooms. The 13mm maximum applies to exterior door thresholds as well — this often requires careful planning when installing new flooring that might raise the interior floor level. Standard door thresholds in older NB homes frequently exceed this height and may need modification during barrier-free renovations.

Surface requirements also matter for accessibility. Flooring surfaces must be stable, firm, and slip-resistant. Thick carpeting that compresses significantly under wheelchair wheels doesn't meet the "firm surface" requirement. Low-pile carpet (under 13mm pile height) with firm backing is acceptable, but hard surfaces like LVP, laminate, or tile are preferred for barrier-free areas.

Practical Planning for NB Homes

Older NB housing stock presents unique challenges for accessibility compliance. Many homes built before 1980 have multiple floor level changes, sunken living rooms, and raised thresholds that require significant modification. When planning barrier-free flooring renovations, you'll often need to level floors across multiple rooms to eliminate transitions entirely.

Moisture considerations remain critical even in accessibility renovations. The same humidity management principles apply — engineered hardwood and LVP perform better than solid hardwood in NB's Maritime climate, and proper moisture barriers are essential over concrete slabs. Don't compromise moisture protection to meet accessibility requirements.

Winter safety is especially important for barrier-free design in NB. Smooth flooring surfaces near entrances can become slippery from snow and ice tracked indoors. Consider textured LVP or slip-resistant tile in entry areas, and ensure transition strips have adequate grip surfaces.

When Professional Help is Essential

Structural modifications for accessibility compliance often require engineering assessment and building permits. If you need to level floors, remove steps, or modify thresholds in load-bearing areas, contact your local building inspection office and consider hiring a contractor experienced with barrier-free renovations.

Compliance verification is crucial for accessibility projects, especially if you're receiving government funding or tax credits for barrier-free improvements. Work with contractors familiar with NBC accessibility requirements and consider having the work inspected to ensure compliance.
