The Town of Grimsby has initiated a Grimsby Official Plan Amendment and Zoning By-law Amendment to conform with changes to Provincial legislation, regulation, policy and plans specifically regarding Additional Residential Units (ARUs). The amendments include minor fixes, such as aligning definitions between documents, and clarifying provisions and references.
Application Type
Zoning By-law and Official Plan Amendment for the proposed municipally led Official Plan and Zoning By-law Amendment for Additional Residential Units in Grimsby.
Agent
Agent: The Corporation of the Town of Grimsby
Proposed Amendment
ARUs are self-contained dwelling units that contain living space, kitchen, and bathroom facilities. ARUs are considered “additional” as they are located on the same lot as the primary residential dwelling, such as a single detached, semi-detached, or street town house dwelling. To comply with the changes the following is proposed:
- To permit up to 2 Additional Residential Units on municipally serviced lots within the Town’s Urban Settlement Boundary where a single-detached, semi-detached, or street town house dwelling is permitted, and subject to further conditions of the Town’s Official Plan and Zoning By-law.
- To align with O. Reg 299/19, it is proposed that Grimsby’s Zoning By-law permits tandem parking configurations for ARUs. For municipally serviced lands within the Urban Settlement Boundary, the Zoning By-law must permit up to 45% lot coverage on lots that contain an ARU, and exempt buildings or structures that contain ARUs from angular plane requirements.
- To permit 1 Additional Residential Unit on privately serviced Rural and Agricultural lands where a single detached house is permitted, subject to further conditions.
This amendment also proposes to expand permissions regarding ARUs to the Hamlets, allowing 1 Additional Residential Unit on privately serviced lands where a single detached dwelling is permitted, and subject to further conditions of the Town’s Official Plan and Zoning By-law.
This project was initiated by the Town of Grimsby on May 12, 2025 through PA25-14.
The purpose and effect of the Official Plan Amendment and Zoning By-law Amendment is to incorporate Provincial legislation, regulation, policy, and plans specifically regarding Additional Residential Units in the Town of Grimsby and ensure that ARUs are not hindered by the Zoning By-law and Grimsby Official Plan. The amendments include minor fixes, such as aligning definitions between documents, and clarifying provisions and references.
