The Infill Construction Process in Calgary: A Step-by-Step Guide
TL;DR: Calgary’s infill construction process follows five main stages: discovery and lot assessment, design and feasibility, permitting and approvals, construction, and handover. The full timeline typically runs 12 to 18 months. Here’s what happens at each step, what it costs, and what you need to know before you start.
Building an infill in Calgary is one of the most financially rewarding projects you can take on, but only if you understand the process before you start. Too many property owners jump into infill development without a clear picture of what’s involved, and that’s where timelines slip, budgets grow, and frustration sets in.
At Jenga Built, we’ve designed our turnkey process to take the complexity off your plate. Whether you’re an investor building a multi-unit rental property or a landowner redeveloping your own lot, here’s exactly what to expect at each stage. If you’re still exploring which zoning district applies to your lot, start with our guides on R-CG zoning and Calgary’s zoning landscape.
How Long Does Infill Construction Take in Calgary?
A typical Calgary infill project takes 12 to 18 months from the initial assessment to move-in day. The timeline breaks down roughly as follows: 1 to 2 months for assessment and design, 2 to 4 months for permitting and approvals, and 6 to 10 months for construction, depending on project size and complexity.
- Project complexity: A duplex is faster than a 4-plex or 8-unit development.
- Permitting path: Straightforward R-CG projects move through permits more quickly. Projects requiring variances take longer.
- Calgary’s Infill Fast Track Program: Qualifying projects using pre-approved designs can move from application to approval in approximately 8 weeks.
- Season: Calgary winters can slow exterior construction. Projects timed to start foundations in spring often have the smoothest schedules.
Step 1: Discovery Consultation and Lot Assessment
The first step in any infill project is understanding what your lot can actually produce. This is where Jenga Built’s process begins: with a Free Lot Assessment. During the assessment, we visit your property to evaluate lot size, dimensions, grade, lane access, and existing structures. We review your zoning — whether your lot is designated R-CG, R-G, or H-GO — and explain what that means in plain English.
After the visit, you receive a written Lot Potential Summary with your zoning assessment, 2 to 3 development scenarios with estimated costs and projected values, and our recommended next steps. This step is free, takes about 45 minutes, and carries no obligation. Book yours here.
Step 2: Design and Feasibility Package
Once you decide to move forward, the next step is a $5,000 Design and Feasibility Package that delivers custom architectural plans, detailed cost estimates, and a complete project roadmap tailored to your lot and goals. This fee is fully credited if you build with Jenga Built.
- Custom design: Our architects create a design maximizing unit count and livable space within the zoning rules that apply.
- Cost estimate: A detailed construction budget covering hard costs and soft costs. No surprises.
- Financial projections: Projected finished values, rental income estimates, and ROI analysis for investors.
- Project timeline: A realistic schedule from permitting through construction.
- Zoning compliance review: Our team ensures the proposed design meets all zoning requirements.
Step 3: Permitting and Approvals
Permitting is where many infill projects stall. At Jenga Built, we handle all development permits, building permits, and any required variances with the City of Calgary so you don’t have to navigate the bureaucracy yourself.
- Development Permit (DP): Review typically takes 6 to 12 weeks for straightforward R-CG projects. Calgary’s Infill Fast Track Program may see approvals in as little as 8 weeks.
- Building Permit (BP): Once the DP is approved, we submit detailed construction drawings including structural engineering, mechanical, electrical, and plumbing plans.
- Additional approvals: Depending on your project, we may also handle utility connections, tree protection plans, grading permits, and demolition permits.
Step 4: Construction
For a typical 4-unit infill in Calgary, expect 6 to 10 months of active construction. Here’s the general sequence:
- Site preparation (2-4 weeks): Demolition, excavation, and site grading.
- Foundation and framing (6-10 weeks): The concrete foundation is poured, framing goes up.
- Mechanical, electrical, and plumbing (4-6 weeks): All systems installed and inspected before walls are closed.
- Interior finishing (6-10 weeks): Insulation, drywall, flooring, cabinetry, fixtures, paint, and appliances.
- Exterior and landscaping (2-4 weeks): Siding, roofing, driveways, walkways, and landscaping.
Step 5: Handover and Aftercare
Handover includes a final inspection, detailed walkthrough, warranty registration, and ongoing support to make sure your investment performs from day one. All Jenga Built homes are registered under Alberta’s new home warranty program. If you’re renting units, we can help with initial tenant setup and provide guidance on maximizing rental income.
What Does Infill Construction Cost in Calgary?
Multi-unit builds typically range from $225 to $275 per square foot for hard construction costs, before soft costs and land acquisition. Here’s a rough breakdown for a standard 4-unit infill:
- Hard construction costs: $720,000 to $880,000 (based on ~3,200 sq ft total)
- Soft costs (permits, design, engineering, surveys, insurance): Add 10–15% to hard costs
- Land acquisition: Varies dramatically by neighbourhood. See our guide to the top 5 Calgary infill areas for ROI
- Total project cost (land + build): Typically $1.2M to $2.5M+ depending on location and unit count
