On June 26, 2025, Winnipeg City Council passed By-Law 59/2025. Overnight, a 50-foot R1 lot with a paved back lane went from one door to four. If you own a lot in Fort Rouge, St Vital, or any mature Winnipeg neighborhood and you’re not running the new math on Winnipeg infill construction, you’re leaving six figures per door on the table.
The bylaw is not the story. The story is that three-quarters of the lots being listed as “infill opportunities” on MLS will not pencil under it. The other quarter will, and hard. Those are the ones quietly getting picked up by investors who read the bylaw twice.
Here’s what By-Law 59/2025 does, what it doesn’t, and what a qualifying small multi-family Winnipeg project actually costs to build in 2026.
What most investors get wrong
By-Law 59/2025 is not a rezoning. It does not let you build whatever you want. It removes the public hearing and variance process for specific unit counts on specific lot configurations. Everything past that, height, setback, servicing capacity, parking, still governs the build. Full text is on the City of Winnipeg infill housing page.
Three mistakes we see every week:
- Buying a lot without verifying rear lane paving. Triplex and 4-plex rights require it. An unpaved lane knocks the lot back to duplex.
- Assuming every 50-foot lot pencils as a 4-plex. Lot depth, servicing capacity, tree preservation, and creek setbacks on Omand’s, Bunn’s, Sturgeon, and Truro all reshape the envelope before a shovel hits dirt.
- Underwriting hard cost at $160/SF because that’s what a 2021 pro forma shows. That number is dead. Building it into the deal costs you 25 percent on the projection and a cash-flow date that never arrives.
Winnipeg infill construction: what By-Law 59/2025 unlocks
The changes are permanent, citywide, and as-of-right. In plain language, no public hearing, no Community Committee, no variance fight for qualifying builds. See how Summit Design Build handles small multi family construction in Winnipeg.
The lot width math
- Duplex (up/down): 25 ft minimum frontage
- Triplex: 35 ft with paved rear lane
- 4-plex: 50 ft with paved rear lane, or 60 ft mid-block with front drive
- Height: 30 to 35 ft standard, up to 39 ft and four storeys within 800 m of high-frequency transit
A standard 50 x 120 lot in Fort Rouge now carries four doors. A narrow 25 x 100 West End lot now carries two. Single-family remains legal everywhere the new units are allowed, so you are not forced into density if the math says hold.
Parking, setbacks, and the creek rule
Parking minimum drops to one stall per unit, zero in corridor overlay districts. That single change saves 80 to 120 SF per unit on narrow lots.
If the property backs onto Omand’s, Bunn’s, Sturgeon, or Truro Creek in R2 or RMF-S, a 25 ft rear setback applies. Check this before you offer.
What Winnipeg infill construction actually costs in 2026
Real numbers from active Summit projects.
Hard cost per square foot
Summit’s 2026 build cost runs around $180 per SF on small multi-family Winnipeg projects, from duplex construction Winnipeg work through 4-plex Winnipeg scopes. That is the all-in hard cost, demolition included. Soft costs (design, permits, engineering, surveys, insurance, financing) run another $5 per SF.
For reference, the Altus Group Canadian Cost Guide puts Winnipeg single-family builds at $175 to $265 per SF. Small multi-family runs lean to that range when the design is shaped around the unit envelope instead of stretched to look like a detached house.
The full stack on a Fort Rouge 4-plex
Take a 4-plex with a realistic investor unit mix: two 3-bedroom units at 1,450 SF and two 2-bedroom units at 750 SF. Total building: 4,400 SF on a 50-ft R1 lot in Fort Rouge with a paved lane.
- Hard construction at $180/SF (demo included): $792,000
- Soft costs at $5/SF: $22,000
- Total construction budget: $814,000, land excluded
- Land basis on the 50-ft Fort Rouge lot: $225,000
- Total project cost: $1.04M
That is ~$260,000 per door, all-in. Market rent on a new 3-bed in Fort Rouge, St Vital, or comparable mature neighborhoods supports that number with headroom. A 2-bed supports it easily.
Where the surprises come from
Servicing capacity. The City reviews water and wastewater servicing case by case until citywide studies close. A 4-plex permit on a street with aging mains can get held pending upgrade costs. This is the one line on the pro forma that moves most often, and the one worth pricing before the offer is firm.

The Edderton case study
Summit’s Edderton project is complete. Fifty-foot lot, subdivided into two 25-foot parcels, each carrying a duplex with a legal secondary suite. Four doors total on what was one door before the subdivision.
- Lot subdivision: formalized existing lines, no variance required under the new bylaw
- Build type: two up-down duplexes, each with a secondary suite
- Hard cost: $180/SF across the pair
- Delivered per-door cost: cleanly below current rent-driven valuation in the neighborhood
That is the blueprint, proven. And it’s running right now across Summit’s active 2026 book:
- St Boniface: 6-plex infill on a through-lot
- St James: 4-plex on a paved-lane 50-ft lot
- North Kildonan: up-down duplex on a 33-ft parcel
- The Forks: larger-format multi-family project
- Old St Vital: triplex on a 35-ft lot with lane
Same bylaw, same construction cost structure, different rent comp depending on the block.
“Won’t my neighbors fight this?”
Under infill zoning Winnipeg rules, they cannot. Qualifying builds skip the public hearing. No Community Committee, no variance fight, no 60-day appeal window on the rezoning itself. Permit-level neighbour notification still applies on certain items, but the structural approval is off the table.
This is the largest change in Winnipeg investor math in a decade. The old timeline of 9 to 14 months from offer to permit, longer if a variance went to the Manitoba Municipal Board, is done for qualifying lots. New timeline runs 12 to 16 weeks from accepted offer to building permit when the drawings are clean and the lot is clear.
Why the math works right now
Winnipeg is the cheapest urban build in the country. Against Toronto, Vancouver, or Ottawa, we’re building the same unit for 40 to 60 percent less per door. Pair that with rents on new infill stock up 18 to 25 percent since 2022 and a bylaw that just collapsed permit timelines from a year to a quarter, and the cap rate math is not tightening. It’s opening up.
The lots that pencil will not stay unlisted. The investors moving in Q2 and Q3 of 2026 are the ones who will set the comp set for the next five years.
The only question that matters: can this specific lot carry the doors at this cost at this rent. Lot width, lane access, servicing capacity. Knowable in an afternoon.
This is the play
By-Law 59/2025 is the largest deregulation of Winnipeg residential zoning since Unicity. Every 25, 35, and 50-foot lot in R1, R2, and RMF-S just picked up a new ceiling. The bylaw did not change the cost of construction, the capacity of the water main, or the time it takes to frame a wall. It changed what’s allowed on the land you already own, or are about to buy.
