What this bill does
This Ontario bill amends the Building Code Act, 1992 to require that all newly built houses with a garage, carport, or driveway be pre-wired with the electrical infrastructure needed to support future installation of electric vehicle charging equipment, including a minimum 200 amp panel, conduit, and an electrical outlet box.
Plain-language summary by Legisail.
Business impact
Compliance
This bill directly affects residential home builders and construction contractors in Ontario who build single-family or Part 9 houses (typically houses up to 600 square metres). On a day-to-day basis, it changes how they plan and execute the electrical rough-in for new homes — they'll need to install a 200 amp panel, a 27 mm conduit run to the garage or driveway area, and a 4-11/16 inch outlet box as standard practice. Electrical subcontractors working on new residential builds will also be impacted, as they'll need to incorporate EV-ready wiring into every qualifying home. Both small custom home builders and larger volume builders/developers will be affected equally, though larger developers may feel the cumulative material and labour cost increase more acutely across subdivisions.
