Densification Study | Policy Economics
The Policy Dials That Decide Whether Kelowna Densification Pencils
Permitting a building type and making it financially buildable are different acts. The VanPlex densification model was built to separate them: it holds the market constant and turns the policy dials one at a time across 9,844 real lots. This page names each dial, what it is worth in dollars or square metres, and what the model measures when it moves.
Key Takeaways
- ✓DCC relief is the City's biggest single fee lever: $28,943 per added home at Residential 3 density in the Main City sector.
- ✓Parking is land arithmetic: about 30 m² per surface stall, competing with the building on ~600 m² lots.
- ✓Intensity cuts both ways: the test lot's 6-storey falls from MARGINAL to NON-VIABLE between 100% and 90% buildout.
- ✓The cost basis is the biggest non-policy variable: the same lot flips bands between the Altus and VanPlex bounds.
The Dials and What They Are Worth
| Lever | Who holds it | What it is worth |
|---|---|---|
| DCC relief (full / half / waived) | City of Kelowna | DCCs run $28,943 per added home at Residential 3 density and $27,671 at Residential 4 in the Main City sector (Bylaw 12420, revised January 27, 2025). On a 12-home project that is a fee line in the hundreds of thousands, charged on added homes only. |
| Required parking per home | City of Kelowna | Zoning Bylaw 12375 requires 1.0 to 1.6 stalls per home for Core Area apartments outside the Transit-Oriented Areas, where the minimum is zero. Each surface stall consumes about 30 m² of yard; each podium stall about 32 m² of ground floor. |
| Lot coverage cap | City of Kelowna | Today: 55% for 3-plus-unit projects, 85% modeled for the arterial podium form. Coverage decides the floor plate, and the floor plate times the storey count is the whole revenue side. |
| Setbacks | City of Kelowna | Standard (today’s bylaw: 3 m front, 1.8 m side in MF1) versus a relaxed set (2 m front, 1.2 m side). On a 14 m wide lot, 0.6 m per side is 8.6% of the buildable width. |
| Construction cost reality | The market, not policy | The model brackets it: the Altus 2026 guide basis (Vancouver 6-storey wood-frame hard cost $255 to $360 per sq ft, Kelowna adjusted about 10% lower) is the optimistic bound; the VanPlex observed $365 per sq ft all-in is the conservative bound. |
DCC rates: City of Kelowna DCC Bylaw 12420. Zoning values: Zoning Bylaw 12375. Cost bounds: Altus Group 2026 Canadian Cost Guide and the VanPlex Kelowna proforma, as carried in the densification model Rev 1.6.
Four Measured Findings
Buildout intensity is brutal on viability
On the study’s test lot, the arterial 6-storey sits in MARGINAL at 100% buildout and falls to NON-VIABLE by 90%. Fixed costs (land, servicing, frontage) do not shrink with the building, so revenue falls faster than cost.
The cost basis flips the whole map
At the Altus basis and today’s fees, 5,478 of 9,844 lots clear a 15% margin. Switching to the conservative VanPlex cost basis drops most scenarios into NON-VIABLE, which matches the source proforma’s own result for a fourplex. Reality likely sits between the bounds.
DCC relief is the City’s biggest single dial
The study’s README names the DCC toggle the City’s biggest fee lever. Relief scales a per-home charge of roughly $28,000, and because it applies to added homes only, it hits denser projects hardest.
Parking is land arithmetic, and it competes with homes
At 1.0 stall per home, a 12-home core project must find about 360 m² of yard for parking, on lots that average near 600 m². The zero-parking arterial scenario is the policy being tested, and it is current law only inside the four Transit-Oriented Areas.
All four are reproducible on the interactive map: set the dials, watch the band counts in the legend, and click any lot for its budget.
The Land-Price Answer
For every lot and every dial setting, the model solves one closed-form question: the most a builder could pay for this land and still clear a 15% margin. Set beside the lot's 2026 assessed value, that number tells you instantly which side of the ledger is broken. When the maximum supportable land price sits below assessment across a whole corridor, no amount of good intentions produces buildings there; either a policy dial moves or the land market does.
The map has a dedicated color mode for exactly this comparison: Max land price vs assessed.
Best For
- ✓ City staff sizing what DCC relief or a parking change actually buys in viable lots
- ✓ Builders identifying which corridors clear 15% under the conservative cost bound
- ✓ Landowners reading whether their assessment already prices in the upside
Usually Fails When
- ✕ One cost bound is quoted as the answer instead of the range
- ✕ Results at 100% buildout are treated as achievable on every lot
- ✕ Estimate-labeled fee lines are presented as confirmed City charges
What To Verify Before Spending Money
- → Current DCC rates against Bylaw 12420 before quoting any fee total
- → TOA status for any lot where the zero-parking scenario matters
- → Sale price assumptions against current comparables before underwriting
Frequently Asked Questions
What policy levers does the Kelowna densification model test?
Six, all adjustable live on the interactive map: buildout intensity (100% down to 60%), lot coverage caps for both building types, standard versus relaxed setbacks, required parking per home (0 to 1.6 stalls), the construction cost source (Altus 2026 basis or the VanPlex observed all-in cost), and Development Cost Charge relief at full, half, or waived.
How much are Development Cost Charges per home in Kelowna?
Under DCC Bylaw 12420, revised January 27, 2025, a project in the Main City road sector pays $28,943 per added home at Residential 3 density (35 to 85 homes per hectare) and $27,671 per added home at Residential 4 (over 85 homes per hectare). DCCs apply to additional homes only, so an existing house earns a one-home credit.
What builder profit margin does the model treat as viable?
The PlexRank scale from the VanPlex proposal grades margin on total sales value: below 5% is NON-VIABLE, 5 to 15% MARGINAL, 15 to 22% VIABLE, and above 22% STRONG. The 15% line anchors the model’s headline answer, the maximum land price a builder could pay and still hit target.
How many Kelowna lots are viable for 4 or 6 storeys today?
At the model’s defaults (Altus cost basis, full DCCs, 100% buildout), 5,478 of the 9,844 residential Core Area lots reach at least a 15% margin: 350 STRONG and 5,128 VIABLE. Another 3,539 are MARGINAL and 767 NON-VIABLE, with 60 lots lacking an assessed value to compute.
Why does buildout intensity change viability so sharply?
Because the big fixed costs do not scale down with the building. Land, water and sewer upgrades, frontage works, and permits cost nearly the same for a smaller building, while revenue drops in proportion to floor area. On the study’s test lot the arterial 6-storey falls from MARGINAL at 100% buildout to NON-VIABLE at 90%.
What do parking requirements cost in land terms?
The model carries about 30 m² per surface stall including maneuvering, with 60% of leftover yard usable for parking, and 32 m² per podium stall. At the bylaw’s 1.0 stall per home, a 12-home project needs roughly 360 m² for parking, which on a typical 600 m² Core Area lot competes directly with the building footprint.
Is the zero-parking arterial scenario current law in Kelowna?
No, and the model labels it as the policy being tested. Under Zoning Bylaw 12375, zero parking minimums apply only inside the four designated Transit-Oriented Areas at the Rutland, Hospital, OK College, and Orchard Park exchanges. Everywhere else, Core Area apartments require 1.0 to 1.6 stalls per home.
Which construction cost number should I believe, Altus or VanPlex?
Treat them as bounds, which is how the model presents them. The Altus Group 2026 Canadian Cost Guide basis (about $280 per sq ft hard for the 6-storey form in Kelowna, plus 15% soft costs and 5% contingency) is optimistic; the VanPlex observed $365 per sq ft all-in from a built proforma is conservative. The BTY 2026 guide runs higher still, which supports treating Altus as the floor.
What is the maximum land price answer the model produces?
For every scenario the model solves a closed-form question: the most a builder could pay for the lot and still hit a 15% margin after construction, city fees, commissions, and financing. Comparing that number to the lot’s 2026 assessed value shows instantly whether land pricing or policy is the binding constraint.
Where can I test these levers myself?
The interactive map at vanplex.ca/kelowna-densification-map runs all six levers live across 9,844 lots and recolors the city as you drag. Each lot’s panel shows its full budget and its own sensitivity table from 100% down to 60% buildout.
