Development Checklist for BC Multiplex
A complete phase-by-phase checklist covering every step from initial feasibility through occupancy — so nothing falls through the cracks.
Key Takeaways
- ✓ A typical multiplex development takes 18-24 months from first feasibility check to occupancy.
- ✓ The process has 6 major phases: Feasibility, Design, Permitting, Pre-Construction, Construction, Completion.
- ✓ Most delays happen in permitting (8-16 weeks) — prepare complete applications to minimize back-and-forth.
- ✓ Budget 10-15% contingency on top of all cost estimates.
- ✓ Start financing conversations early — construction loan approval takes 4-8 weeks.
The 6 Phases of Multiplex Development

How long does it really take to build a multiplex in BC? +
A typical multiplex development takes 18-24 months from initial feasibility analysis to occupancy. The timeline breaks down roughly as: 4 weeks for feasibility, 8 weeks for design, 12-16 weeks for permitting, 4-8 weeks for pre-construction, 12-14 months for construction, and 4-8 weeks for completion and turnover. Delays in permitting and material supply chains are the most common reasons projects exceed this timeline.
What is the most common cause of delays? +
Permitting is by far the most common source of delays. Incomplete applications trigger rounds of back-and-forth with municipal planners, each adding 2-4 weeks. To minimize this, attend a pre-application meeting, submit complete drawings with all required reports (geotechnical, arborist, energy), and respond to review comments promptly and thoroughly. The second most common delay is long-lead material procurement — ordering windows, mechanical equipment, and custom items early in the pre-construction phase can prevent construction stalls.
Do I need a general contractor or can I be my own project manager? +
For most multiplex projects, hiring a licensed general contractor is strongly recommended. A GC manages subcontractor scheduling, inspections, quality control, and regulatory compliance. Owner-managed builds can save 10-15% on GC markup but require significant construction knowledge, daily site presence, and the ability to coordinate 15-20 different trades. If you have no prior construction management experience, the risk of costly mistakes and delays typically outweighs the savings. A middle ground is hiring a construction manager on a fee basis who oversees the project while you retain more control.
When should I start the financing process? +
Start financing conversations during Phase 1 (Feasibility), ideally within the first 2 weeks. Construction loan approval typically takes 4-8 weeks and lenders will want to see your proforma, site plans, and builder quotes before committing. Getting pre-approved early ensures you know your budget ceiling before investing in design and permitting. Many projects stall because the owner completes design only to discover their financing falls short. Talk to at least 2-3 lenders (a major bank, a credit union, and optionally a private lender) to compare terms.
