Building a residential multiplex is a complex endeavor that involves managing a wide array of challenges, from securing funding and finding the right location to navigating regulatory hurdles and creating functional, sustainable living spaces.

The project demands careful planning, efficient project management, and ongoing attention to the needs of residents and the surrounding community.

Bill 23 in Ottawa

Bill 23, officially known as the More Homes Built Faster Act, is a piece of provincial legislation passed in Ontario, Canada, in 2022. The purpose of the bill is to accelerate the construction of new homes in the province, with the goal of addressing Ontario's housing affordability crisis.

Before Bill 23, property owners were only able to build two (2) units on their property.

After Bill 23, property owners are now able to build three (3) units on their property.

What does it take to build a multiplex?

Market Research

Before embarking on a project, it's crucial to understand the demand for residential housing in the area. Conduct market research to identify the target demographic (e.g., luxury, affordable, or mixed-income housing), assess competition, and determine rental/sale price points.

Financial Feasibility

This includes assessing the project’s potential profitability by estimating construction costs, expected rents or sales prices, and overall return on investment (ROI). You'll need detailed financial projections to secure financing.

Site Selection

Identifying the right location is critical. The plot of land should be in an area with good infrastructure, public transport links, and access to amenities (e.g., schools, shopping centers, healthcare).

The location also needs to be zoned for multi-family residential development.

Initial Planning and Feasibility Study

Project Budgeting

Estimating the total cost of land, design, permits, construction, utilities, marketing, and post-construction operations is essential for developing a solid budget.

Zoning Approval

The land needs to be zoned for multi-family residential use. If it is not, you may need to apply for a rezoning request or variance through the local planning commission or municipal government.

Building Permits

You'll need to secure permits from local authorities for construction, including approvals for site preparation, excavation, electrical, plumbing, and safety features. This process involves submitting detailed plans to the local government for review and approval.

Financing, Zoning and Permits

Architectural

The design phase involves working with architects and designers to create blueprints that meet both your vision and the Ontario Building Code.

Key considerations include:

the layout of residential units,
the number of floors,
common areas (e.g., elevators, hallways, lounges), parking spaces,
and amenities (e.g., gym, rooftop garden).

Engineering and Structural

Structural engineers will need to ensure that the building is safe, compliant with local building codes

Design and Architecture

Construction

Site Inspection

Before construction can begin, the site must be cleared and prepped, which may involve demolition of existing structures, excavation for foundations, and grading of the land.

Foundation and Structure

The foundation is the first phase of actual construction. For a multi-story building, this could include deep foundations such as pilings or concrete footings. Once the foundation is in place, the structural frame (beams, columns, and floors) will be built, followed by walls and ultimately the roofs.

Utilities and Infratstructure

Installing necessary utilities (water, electricity, sewage, gas) and ensuring the infrastructure (like roads, drainage systems, and waste disposal) is in place is a major aspect of construction. The building's plumbing, electrical, HVAC, and fire protection systems are also integrated at this stage.

Exterior and Interior Finishing

Once the structure is complete, the next phase involves adding exterior elements like roofing, windows, and cladding (brick, wood, or other materials). Inside, drywall, flooring, cabinetry, and painting are done to prepare the units for occupancy.

Code Compliant Inspections

Local building inspectors will conduct thorough checks to ensure that the construction meets all safety, electrical, plumbing, and structural codes. These inspections often happen at different stages of construction (foundation, framing, final).

Final Walkthrough

After construction is complete, a final walkthrough is performed to ensure everything is finished to spec. Any issues identified during this inspection need to be addressed before residents can move in.
