AODA Compliance in Commercial Renovations | Ontario Guide

AODA compliance in commercial renovation is one of those areas where clients often do not know what they are obligated to do until a building inspector or their lawyer tells them. This guide covers the key requirements clearly, without the legal language that makes the actual legislation difficult to act on.

What AODA Requires in the Construction Context

The Accessibility for Ontarians with Disabilities Act (AODA) establishes accessibility standards across multiple areas. For construction and renovation, the relevant standard is the Design of Public Spaces Standard, which was phased in starting in 2014-2016 for private sector organizations.

The key trigger for construction obligations is the phrase "newly constructed or redeveloped." When you renovate a commercial space, you are redeveloping it, and that triggers AODA requirements for the elements you are touching.

What Must Be Accessible in a Commercial Renovation

Entrances and doors: Accessible entrances require a minimum clear opening width of 900mm. Power door operators are required for new primary entrances in many building types. If your renovation changes or adds an entrance, this applies.

Corridors and aisles: Accessible paths of travel require a minimum clear width of 1,100mm (1,200mm preferred) to allow wheelchair passage without backtracking.

Washrooms: Any new or significantly renovated washroom must include an accessible stall meeting OBC Appendix E requirements, grab bars, the correct turning radius, proper door swing, and hardware that can be operated with a closed fist.

Reception and service counters: New reception counters must include a lowered portion (760-860mm above floor) for wheelchair users, with minimum 760mm knee clearance below.

Signage: Tactile signage with Braille is required at certain locations, primarily room identification signs and directional signage in certain building types.

Parking: If your renovation triggers site work that includes parking, accessible parking spaces must meet current OBC standards for size, location, and signage.

The OBC Connection

AODA requirements are largely incorporated into the Ontario Building Code. When a permit is required for your renovation, the building inspector will check for compliance with barrier-free design requirements as part of the permit review. If the drawings do not show compliant accessible design where required, the permit will not be issued until they do.

This means AODA compliance is not optional and not subject to enforcement delay, it is built into the permit approval process.

What Triggers Full vs. Partial Compliance

If you are doing a minor renovation, repainting, replacing flooring, changing lighting, in an area that is otherwise untouched, you are not necessarily required to upgrade every accessible element in the building. The obligation attaches to what you are constructing or redeveloping.

However, the OBC contains a provision requiring that renovations not reduce the level of barrier-free accessibility that existed before the renovation. You cannot make a space less accessible in the course of renovating it.

Major renovations that change the primary entrance, add or reconfigure washrooms, or significantly alter the floor plan will trigger more comprehensive compliance review.

Common Problems Found During Permit Review

The most common AODA-related issues that hold up permits on commercial renovation projects:

• Washroom turning radius too small, the required 1,500mm clear turning circle is often missing in compact washroom designs
• Door hardware, lever handles are required; round knobs are not compliant
• Ramp slopes, ramps to accessible entrances must not exceed 1:12 (8.3%). Many existing ramps are steeper and must be corrected when the entrance is modified
• Counter heights, new reception counters drawn at uniform height without a lowered accessible section
• Missing power door operators, required at primary public entrances in many commercial occupancy types

How VNG Handles AODA Requirements

On every commercial renovation project, VNG reviews drawings for AODA compliance before they are submitted for permit. Where drawings show non-compliant elements, we flag them to the client before submission, not after the plan review comes back with comments, which adds 2-4 weeks to the timeline.

AODA compliance is not a design add-on. It is a building code requirement that your contractor should treat as standard scope from the start of the project.
