AODA exterior paths
New or redeveloped outdoor paths for covered owners need set widths, slopes, surfaces, gaps and headroom.
Show the full rule
These rules cover new or redeveloped outdoor paths. They apply to public-sector organizations, and to businesses and non-profits with 50 or more employees. Covered paths need at least 1,500 mm of clear width (1,200 mm at a curb-ramp turning space).
- A running slope (along the path) no steeper than 1:20, or it must be designed as a ramp.
- A cross slope (side to side) no more than 1:20 on asphalt and concrete (we treat concrete pavers and slabs the same way) — 1:10 on other surfaces such as compacted aggregate.
- A firm, stable, slip-resistant surface.
- Openings no larger than 20 mm.
- At least 2,100 mm of headroom.
