Duplex and Triplex Conversion Process in the Greater Hamilton Area

Converting a single-family home into a duplex or triplex involves several renovation and construction steps to create two or three separate, functional living units within the same structure. Here is an overview of the renovation process involved in a duplex or triplex conversion:

Planning and Design

Start by consulting with an architect or designer who specializes in residential conversions. They can help create a design that maximizes space, complies with building codes, and meets your specific needs.

Obtain Necessary Permits

Check with your local municipal authorities to determine what permits and approvals are required for the conversion. You may need permits for structural changes, electrical, plumbing, and zoning compliance.

Structural Modifications

Depending on the existing layout, structural changes may be necessary to create separate living spaces. This can include adding or modifying walls, creating additional entrances, or expanding the building’s footprint.

Electrical, Plumbing, and HVAC

Install separate electrical systems and panels for each unit to ensure safety and compliance with local codes. Similarly, separate plumbing systems for each unit are required. Install separate heating, ventilation, and air conditioning systems for each unit or ensure that existing systems can be independently controlled for each living space.

Flooring and Finishings

Install separate flooring, cabinetry, countertops, and other finishings in each unit. The design and choice of materials should reflect the desired aesthetic and functionality of each space.

Kitchens and Bathrooms

Create or renovate kitchens and bathrooms in each unit, ensuring they meet local building codes and safety standards.

Exterior Modifications

Update or modify the exterior of the building to accommodate separate entrances and ensure the duplex complies with local zoning regulations and aesthetic considerations.

Inspection and Approval

Once the renovation work is complete, schedule inspections by local City of Hamilton building inspectors to ensure compliance with all building codes and regulations.
