MLI Select 2026 Changes: What BC Developers Actually Need to Know About the Energy Side
If you are building multi-unit rental in BC right now, your mortgage broker has probably told you the MLI Select rules changed on November 28, 2025. You also probably heard something about a transition window until September 30, 2026, a new point system, and 2020 NECB or 2020 NBC.
Most of what is online about these changes is written from the financing side of the deal. This one is written from the energy side, because that is the part that actually decides whether you hit your point target. We are a Registered Energy Advisor firm in West Kelowna that does the energy modelling, the compliance documentation, and the CMHC attestations for MLI Select files across the Okanagan.
Here are the questions developers and brokers are asking, with honest answers.
What actually changed on November 28, 2025?
Three things that matter for the energy side of your application.
First, the points structure got simpler. The old program had rigid minimums. The new program gives you a premium discount scaled to how many points you earn:
- 50 points earns a 10% premium discount
- 70 points earns a 20% premium discount
- 100 points earns a 30% premium discount, plus a 50-year amortization
You pick the commitment level that makes sense for your project. You are no longer forced into a package.
Second, the energy baseline for new construction changed. CMHC is now benchmarking energy performance against the 2020 National Building Code (NBC) for Part 9 buildings under four storeys, and the 2020 National Energy Code for Buildings (NECB) for Part 3 buildings that are larger or taller. This replaces the older 2015 NBC and 2017 NECB references.
Third, existing building retrofits are unchanged. If you are buying or refinancing an existing multi-unit and committing to a retrofit, the qualifying criteria you were using before are still in place. The overhaul is specifically for new construction.
What is the September 30, 2026 transition window, and should I use it?
Until September 30, 2026, CMHC will accept applications modelled under the old energy baseline OR the new one. After that date, it is the new 2020 codes only.
In plain terms: if you submit before the deadline, you pick the reference house that is easiest for your project to beat.
The answer to "should I use it" is project-specific, and this is where we see the most money left on the table. The 2020 NECB and 2020 NBC reference houses are more efficient baselines than the 2015 and 2017 versions. That means a project that easily scores 50 points against the older code might only score 35 points against the new one, even with the exact same building envelope. Same building, fewer points, smaller discount.
For most projects we are modelling right now, the fastest path to the highest tier is to run two scenarios: one against the old reference, one against the new. We tell you which scenario gets you more points, you choose, and your broker submits accordingly. If you are going to break ground in 2026, there is a real window to lock in the easier reference, and it closes September 30.
How much money are we actually talking about?
Let us use a real Okanagan example. An 8-unit purpose-built rental in Penticton, budget $4.5M, financed at a typical MLI Select loan structure.
Here is how the premium math lands on that project:
| Scenario | Premium Discount | Approx. Premium Savings | Amortization |
|---|---|---|---|
| No MLI Select | 0% | $0 | 25 years |
| 50 points | 10% | roughly $15,000 | up to 40 years |
| 70 points | 20% | roughly $30,000 | up to 45 years |
| 100 points | 30% | roughly $45,000 | up to 50 years |
Those are just the upfront insurance savings. The bigger number for most developers is monthly cash flow. Stretching from a 25-year amortization to a 45 or 50-year amortization on a project that size reduces monthly debt service by several thousand dollars. Over a decade of holding, it compounds into six-figure territory.
The $200,000+ headline savings on larger projects is real. It is also project-specific, and it only shows up if the energy model is done right the first time.
What does the energy side of MLI Select actually cost?
Here is the question we get asked the most, and here is the honest answer.
For a Part 9 building (under four storeys, under 600 m² per unit, most small to mid-size MURBs), a full MLI Select energy modelling and documentation package from a Registered Energy Advisor in the Okanagan typically runs $3,500 to $9,000. The range depends on:
- Number of units and building complexity
- Whether we are running dual scenarios for the transition window
- Whether you need pre-construction compliance documentation plus a post-construction verification
- Whether we are coordinating with your architect on envelope changes to hit a higher tier
For a Part 3 building (four or more storeys, or larger buildings), you cannot use a Registered Energy Advisor alone. CMHC requires a Professional Engineer, architect, Certified Engineering Technologist, or Certified Energy Manager to prepare the simulation. The fee range is different, typically $8,000 to $25,000 depending on scope, and you should budget for that as a separate professional services line.
For context: the premium savings on a typical 8-unit project at the 70-point tier is around $30,000. The energy modelling and documentation to get you there is a fraction of that. It is usually the highest-ROI spend on the whole file.
Who can actually prepare the MLI Select energy report?
This is the single most common source of confusion we see, and it matters because the wrong credentials will get your application kicked back.
Part 9 Buildings
Low-rise, under four storeys, smaller footprint
A Registered Energy Advisor accredited by Natural Resources Canada can prepare the simulation using HOT2000 or another ASHRAE Standard 140 compliant software. This is our wheelhouse.
Part 3 Buildings
Mid-rise, high-rise, larger commercial-style multi-units
CMHC requires one of the following to sign off on the simulation:
- Professional Engineer (P.Eng.)
- Registered Architect
- Certified Engineering Technologist (CET)
- Certified Energy Manager (CEM)
If you are planning a project near the Part 9 / Part 3 boundary, bring us in at the design stage. Sometimes a minor layout or storey-count decision shifts the building into a category with a different credential requirement and a different fee structure, and it is much cheaper to know that before drawings are finalized than after.
What happens if my project misses the target tier?
This one does not get talked about enough.
Let us say you are targeting 70 points, your broker has already priced the financing around a 20% premium discount, and the final results fall short. What happens?
You drop a tier. Your file qualifies at 50 points and 10% instead of 70 points and 20%. On our 8-unit example, that is roughly $15,000 in lost premium savings plus a shorter amortization.
The ways to avoid that outcome are not complicated, but they all require starting the energy model early:
- Run the model at the design stage, not after permit submission. Early modelling gives your architect room to change an assembly, a window spec, or a mechanical system.
- Build in a margin. If your target is 70 points, design for slighlty higher. Energy modelling accounts for a lot of variables, and as-built performance does not always match the drawing-set model exactly.
- Use the transition window strategically. If the 2020 code reference puts you at 35 points and the 2015 reference puts you at 50, submit before September 30, 2026 under the older reference. That is a legitimate, CMHC-allowed path.
The developers who run into trouble are the ones who treat the energy model as a final-step compliance task. It is not. It is a design tool.
When is MLI Select not worth it?
This is the section our competitors rarely write. We will.
MLI Select is not a good fit for every project. Skip it if:
- You are building four units or fewer. MLI Select requires a minimum of five self-contained rental units.
- You are a flip-and-sell developer. The benefits of MLI Select compound over the hold period. If you are not holding, conventional financing is often cleaner.
- You do not have the project management capacity. MLI Select adds planning, documentation, and reporting obligations across the affordability, energy, and accessibility commitments. On a small, lean team, this can eat hours you do not have.
- Your deal only works at maximum leverage with a 10-point commitment. The 50-point tier gets you a 10% discount, not 30%. That is real but modest. If the pro forma only works at 10% off, the project is probably too thin.
For most purpose-built rental developers holding the asset long-term, the math works. For the scenarios above, it often does not. We would rather tell you that at the first phone call than at the invoice stage.
What do developers usually get wrong on the energy side?
These are patterns we see repeatedly on Okanagan projects:
- Treating the energy audit as an afterthought. Engaging an Energy Advisor after permit submission means the design is locked. You are stuck with whatever points the current assemblies produce.
- Assuming that Step Code compliance equals MLI Select points. They are related but not the same. A Step 3 design may or may not hit the 20-point energy level under MLI Select, depending on the reference house and the building geometry. They need to be checked against each other, not assumed.
- Specifying windows before checking the model. We have seen Chinese import windows quoted on BC projects that do not meet Climate Zone 5 minimums, let alone MLI Select point thresholds. A quick check against the HOT2000 model before the PO is placed prevents a costly reorder.
- Ignoring PV and other renewables as a points lever. A modest rooftop solar array can lift a project from 50 to 70 points on the energy side. It needs to be modelled in HOT2000 to be credited. Saying "we are solar-ready" on a drawing sheet does not earn you a point. Solar production is also capped at a 15% annual energy consuption reduction. You can't rely on solar alone, it is an offset not a reduction.
The short version
- The 50 / 70 / 100 point tiers now map directly to 10% / 20% / 30% premium discounts.
- The new energy baseline for new construction is 2020 NBC (Part 9) and 2020 NECB (Part 3).
- Until September 30, 2026, you can still model against the older reference, which is often an easier target.
- Existing building retrofits are not affected by the 2026 changes.
- The energy model needs to come in at the design stage, not after permit, if you want to hit your target tier.
- Who can sign the report depends on whether your project is Part 9 or Part 3.
If you are planning a multi-unit project in the Okanagan and want to know which tier your design is likely to hit before you commit to it, that conversation is what we do. Send us the drawings and a short summary of your target financing, and we will run a quick scenario against the current design so you know where you stand before the file moves to CMHC.
