Tax and regulatory
Bill 23
Also known as: More Homes Built Faster Act
The More Homes Built Faster Act, passed by Ontario in late 2022. Opened up garden-suite and ADU zoning across nearly every municipality in the province as-of-right, eliminated most development charges on secondary units, and shifted the framework from “can I build a secondary unit?” to “does it pencil?”.
The regulatory unlock is real, but every municipality has its own implementation: setback rules, lot coverage limits, building permit fees, and site plan rules vary. Check your specific municipality's zoning bylaw before falling in love with a design.
For homeowners with the right lot and equity, a Bill 23 garden suite is one of the highest return-on-property moves available in Ontario right now. Math: Garden Suite Build vs Status Quo Calculator. Deep walk-through: Garden Suites in Ontario: The Bill 23 Math.
