Ontario's Bill 23, also known as the More Homes Built Faster Act, has been passed to increase affordable housing by making it easier to build Additional Residential Units (ARUs) in existing homes. This law mandates municipalities to allow ARUs in single-family homes, townhouses, and semi-detached houses. ARUs can be either attached or detached from the primary residence, and include apartments, basement suites, and backyard cottages. The legislation aims to create additional housing options without requiring the construction of new buildings, thereby making better use of existing infrastructure and land.

Accessory Dwelling Units (ADUs) are gaining popularity as a housing solution for a variety of needs. ADUs are small, self-contained living spaces that are typically located on the same property as a primary residence. They are designed to provide additional living space, often for family members or as rental units, while minimizing the impact on the existing neighborhood.

There are several benefits to building an ADU. One of the main advantages is the ability to create additional living space on a property without requiring a new lot or changing the existing zoning of the property. This can be particularly helpful for families who need extra space for aging parents or adult children who are still living at home.
