Developing Middle Housing in Calgary: The Complete Guide for Homeowners and Investors

The Middle Housing Opportunity in Calgary

Calgary’s housing market is experiencing a transformation that presents unprecedented opportunities for homeowners and investors. The recent city-wide rezoning initiative has opened the door to middle housing development across Calgary, creating new possibilities to maximize property value and address housing needs.

At Turn Key Homes & Renovations Renovations, we’ve guided numerous clients through successful middle housing projects – from basement suite conversions to full multi-unit developments. As Calgary’s trusted renovation and construction experts, we’re sharing our comprehensive guide to help you navigate this exciting opportunity.

What is Middle Housing?

Middle housing refers to multi-unit residential buildings that bridge the gap between single-family homes and larger apartment buildings. These include:

Duplexes and semi-detached homes
Triplexes and fourplexes
Townhouses and rowhouses
Secondary suites and laneway homes
Garden suites and garage suites

These housing types provide gentle density in established neighborhoods while maintaining the scale and character of residential areas. They’re called “missing middle” because they’ve been largely absent from North American housing development in recent decades, creating a gap between single-family homes and apartment buildings.

The Calgary Advantage: Why Now is the Perfect Time

Calgary’s 2024 city-wide rezoning initiative has fundamentally changed the development landscape. Many residential areas have been upzoned to R-CG by default, providing as-of-right permission for duplexes, townhouses, and fourplexes on lots that were previously restricted to single-family homes.

This policy change eliminates the need for lengthy land use redesignation (rezoning) processes in most cases, dramatically reducing the time and uncertainty involved in middle housing projects.

For homeowners, this creates opportunities to:

Add rental units for additional income
Create multi-generational living spaces
Increase property value through development
Build wealth through real estate

For investors, the advantages include:

Strong rental demand across Calgary
Simplified approval processes
Multiple financing options including CMHC programs
Higher yields compared to single-family homes

Step-by-Step Development Process

1. Property Assessment and Feasibility

Before diving into a middle housing project, it’s essential to determine what’s possible on your property:

Check your zoning: Every property in Calgary has a land use designation that dictates what can be built. Use the City’s online mapping system to confirm your current zoning:

R-C1: Typically limited to one single-detached dwelling (with a secondary suite in some cases)
R-C2: Allows for one or two dwelling units (e.g., a duplex or semi-detached)
R-CG: Allows rowhouses and multiplex buildings (e.g., fourplexes)

HGO (Housing Growth Overlay) Districts:

In addition to the standard zoning designations, Calgary has implemented Housing Growth Overlay (HGO) districts that provide additional flexibility for middle housing development:

HGO-1 (Housing Growth Overlay – Contextual):

Allows up to 4 dwelling units per parcel
Maximum building height of 11 metres (approximately 3 stories)
Applies contextual design standards to ensure compatibility with surrounding neighborhoods
Reduced parking requirements (minimum 0.5 stalls per dwelling unit)
Streamlined approval process for qualifying developments

HGO-2 (Housing Growth Overlay – General):

Allows up to 8 dwelling units per parcel
Maximum building height of 16 metres (approximately 4-5 stories)
More flexible design standards while maintaining neighborhood compatibility
Minimum 0.5 parking stalls per dwelling unit
Suitable for areas with good transit access and infrastructure capacity

Key HGO Advantages:

Expedited approvals: HGO designations often allow for administrative approval rather than requiring full development permit review
Density bonusing: Higher unit counts possible on standard residential lots
Reduced parking requirements: Recognizes that middle housing residents often have lower car ownership rates
Design flexibility: Standards focused on compatibility rather than rigid prescriptive requirements

How to Check HGO Status: Use the City of Calgary’s online mapping system to determine if your property falls within an HGO district. Properties with HGO overlay designations will show both the base zoning (e.g., R-CG) and the overlay district (e.g., HGO-1).

Assess your lot: Key considerations include:

Lot size and dimensions (width is especially important)
Access to lanes or streets
Corner lot status (often ideal for multi-unit infill)
Existing structures and their condition
Utility services and capacity

Financial feasibility: Create a preliminary budget considering:

Land value/equity position
Construction costs ($225-300+ per square foot depending on finishes)
Soft costs (permits, design, engineering)
Financing costs and options
Potential rental income or sale revenue

At Turn Key Homes & Renovations Renovations, we provide complimentary initial assessments to help you understand what’s possible on your property and the approximate costs involved.

2. Project Planning and Design

With basic feasibility confirmed, it’s time to develop a detailed plan:

Design considerations: Work with an experienced architect or designer to create plans that:

Maximize allowable units and square footage
Meet Calgary’s planning guidelines
Address community context
Incorporate quality features that appeal to renters or buyers

Key regulations to satisfy:

Land Use Bylaw requirements (setbacks, height, lot coverage)
Alberta Building Code standards
Fire separation between units
Parking requirements (minimum 0.5 stalls per unit in R-CG)
Energy efficiency standards

Property strategy decisions:

Build to rent or build to sell?
Individual unit configuration and size
Standard vs. premium finishes
Common area responsibilities

Turn Key Homes & Renovations’s design team specializes in middle housing projects, creating spaces that maximize functionality while maintaining neighborhood character.

3. Budget Refinement and Financing

With preliminary designs complete, it’s time to refine your budget and secure financing:

Construction budget components:

Demolition and site preparation
Foundation and structural work
Framing and building envelope
Electrical, plumbing, and HVAC systems
Interior finishes and fixtures
Exterior works (landscaping, parking)
Contingency allowance (15-20% recommended)

Financing options:

Home equity lines of credit
Construction mortgages
CMHC MLI Select program for rental projects
Builder financing arrangements
Investment partnerships

Turn Key works with trusted financial partners to help clients secure appropriate financing, and our transparent budgeting process eliminates surprises.

4. Permitting and Approvals

Navigating Calgary’s permit system is often the most challenging part of developing middle housing:

Development Permit (DP): Addresses planning and land use aspects of your project.

Required for most new developments
Reviews compliance with zoning regulations and Land Use Bylaw
Involves public notice and feedback period
Takes approximately 3-4 months for typical middle housing projects

Building Permit (BP): Focuses on technical building safety and code compliance.

Requires detailed construction drawings
Includes structural, electrical, mechanical plans
Takes approximately 1 month after DP approval
May include separate trade permits

Turn Key advantage: Our team has extensive experience navigating Calgary’s permit system, with established relationships at City Planning and deep knowledge of approval requirements. We handle the entire permitting process on your behalf, saving you time and frustration.

5. Construction Process

With permits in hand, construction can begin:

Typical construction timeline:

Site preparation and demolition (1-2 months)
Foundation and services (1 month)
Framing and structure (1-2 months)
Rough-ins of services (1-2 months)
Interior and exterior finishes (2-4 months)
Final inspections and approvals (2-4 weeks)

Quality assurance:

Regular site inspections
Municipal inspections at key stages

At Turn Key Homes & Renovations, we maintain transparent communication throughout construction with our online project management software, giving clients real-time updates on scheduling, progress photos, and important milestones.

6. Final Steps and Compliance

After construction, several important steps ensure your project is legally completed:

Post-construction approvals:

Final occupancy approval
Development permit condition fulfillment
Address registration
Home warranty enrollment

For rental units:

Business licensing requirements
Residential Tenancy Act compliance
Insurance updates
Property management setup

Turn Key Homes & Renovations provides comprehensive support through these final stages, ensuring all regulatory requirements are satisfied before handing over your completed project.
