Angular Plane Requirements for Garden and Laneway Suites

The newly introduced Ontario Regulation 462/24 under the Planning Act targets improvements for Additional Dwelling Units (ADUs), such as garden suites and laneway suites. Key changes include:

1. Revocation of Angular Planes: Structures for ADUs can now exceed angular plane limits, promoting innovative and flexible designs.
2. Reduced Separation Distances: Minimum spacing between buildings with residential units is reduced to 4 meters, supporting densification.
3. Relaxed Lot Coverage and FSI Rules: ADU developments can utilize up to 45% lot coverage without a floor space index limit.

This amendment prioritizes housing diversification while encouraging compact and sustainable development.

For developers and homeowners, this marks a significant step toward addressing housing supply issues. Stay tuned for how municipalities implement these changes in zoning by-laws.
