Build-to-rent is not a building type. It’s a tenure decision. You build a multiplex and hold it as rental instead of stratifying and selling individual units. The building itself can look identical either way. The difference is ownership structure, financing, and how you make money.
The Tenure Decision
You own a 6,000 sq ft lot in Vancouver. Under R1-1 zoning, you can build a 6-unit multiplex and sell each unit individually as strata. Or you can build an 8-unit secured rental multiplex and hold all of them.
Same lot. Same neighbourhood. Different financial structure. Different regulatory pathway. Different outcome over 10, 20, 30 years.
Strata gives you a one-time profit event. You build, you sell, you move on. The return is immediate and taxable as income (or capital gains if structured carefully).
BTR gives you a compounding asset. You build, you hold, you collect rent. The return is slow at first — but the asset appreciates, the mortgage amortizes, and rents rise. Over 25 years, you own a debt-free building throwing off six figures in annual net operating income.
Neither model is universally better. The right choice depends on your lot, your cost structure, your financing access, and your timeline.
Why BC Specifically
Three things converged in BC between 2023 and 2026 that made small-scale BTR viable for the first time.
Bill 44 (November 2023) — BC mandated that every municipality over 5,000 residents allow multiplex housing on single-family lots. This was not optional. The Province set compliance deadlines: June 30, 2024, for initial bylaw amendments, and June 30, 2026, for full OCP alignment under Bill 25. As of early 2026, over 498 multiplex applications have been filed in Vancouver alone.
Vancouver’s R1-1 District Schedule — Vancouver went further than the provincial minimum. Under R1-1, secured rental projects on lots 557 m2+ with 15.1m frontage get a density bonus: 1.00 FSR instead of 0.70, and up to 8 units instead of 6. Secured rental projects are also exempt from density bonus contributions — a fee that can run $82,000+ per unit on market strata projects.
CMHC MLI Select — The federal government’s multi-unit mortgage insurance program requires a minimum of 5 rental units. It offers up to 95% loan-to-value, amortizations up to 50 years, and premium discounts of 10-30% based on a points system (affordability, energy efficiency, accessibility). This is the financing that makes the hold model pencil.
No other province has all three. Ontario doesn’t have a Bill 44 equivalent. Alberta doesn’t have the rent levels. Quebec’s rent controls make the math harder. BC is the testbed.
How R1-1 Changes the Math
The density bonus for secured rental in Vancouver’s R1-1 zone isn’t just 2 extra units. It changes the entire financial model.
At 0.70 FSR on a 6,000 sq ft lot, you get 4,200 sq ft of buildable space. Divide that into 6 strata units and you’re looking at roughly 700 sq ft per unit.
At 1.00 FSR, you get 6,000 sq ft. Divide into 8 rental units and each unit is 750 sq ft — larger units with more total building area.
The additional 1,800 sq ft of buildable space at approximately $425/sq ft in hard costs represents about $765,000 in additional construction cost. But those 2 extra units generate rental income that feeds directly into DSCR calculations for CMHC qualification.
More units = more rental income = stronger CMHC qualification = better financing terms = lower equity requirement.
Where BTR Works — And Where It Doesn’t
BTR works on lots where:
-
The lot qualifies for 5+ units — This is the CMHC threshold. Four units means conventional financing at 20% down with 25-year amortization. Five units means CMHC MLI Select at potentially 5% down with 50-year amortization. This single threshold changes everything. (Read more about the 5-unit threshold)
-
Rents cover debt service — CMHC requires a minimum 1.10 debt service coverage ratio. Your net operating income must exceed annual mortgage payments by at least 10%. In lower-rent areas of Metro Vancouver, this doesn’t clear. In higher-rent neighbourhoods with transit access, it does.
-
Land cost is reasonable relative to revenue — A $3.5M lot in Kitsilano produces the same rent as a $2.1M lot in East Vancouver, but the financing math is dramatically different.
BTR does not work on lots where:
- Land cost eats the model — West Side Vancouver lots at $3M+ make the DSCR nearly impossible to clear without below-market land acquisition
- Zoning caps at 4 units — Some municipalities haven’t implemented Bill 44’s 6-unit near-transit provisions yet
- The neighbourhood doesn’t support rental premiums — New-build rental commands $2,400-3,200/month in Vancouver depending on unit size and location. If market rents in your area are $1,800 for a 2-bedroom, the math doesn’t pencil.
The Honest Picture
BTR is not passive income from day one. Year one through five, you’re likely cash-flow neutral or slightly negative after accounting for vacancy, maintenance reserves, and property management. The wealth creation comes from mortgage paydown and asset appreciation compounding over a decade or more.
It’s also not simple. You need to qualify for CMHC MLI Select, which means navigating a points system, commissioning energy modelling, and potentially committing to affordability or accessibility standards. You need a property management strategy from day one. You need to understand the Residential Tenancy Act because once those units are occupied, your obligations are real and ongoing.
But for the right lot, with the right financing, held by an owner with a long-term horizon — BTR multiplex in BC is a structurally advantaged investment that didn’t exist before 2024.
The zoning is by-right. The financing is government-backed. The demand for rental housing in Metro Vancouver isn’t going anywhere. CMHC’s Spring 2026 report showed rental completions running at 2x the ten-year average nationally, and purpose-built rental starts exceeded condo starts in Toronto for the first time on record.
The question is whether your specific lot and your specific financial situation make the hold model better than the sell model. That’s the analysis that matters. (Compare the two proformas side by side)
