Multiplex & Infill Development

Multiplex & Infill Development

Civil engineering for homeowners and small developers under B.C.’s new density rules. We scope the work to what the permit requires, price what the density triggers, and carry it through to completion.

The bylaw says you can build four units. The street was built for one.

Off-site upgrades. Stormwater retention for the new impervious area. Service tie-ins on a road that never expected this density. Infill margins are thin, and these three usually decide whether the project works, so we price them first.

This is for you if:

  • You own the lot and want to know if it can carry more units
  • You’re evaluating a property to buy and infill
  • You need to price the upgrades before you commit
  • You have an architect’s concept and need the civil work to match

What’s Included

  • Feasibility + lot analysis
  • Grading + drainage
  • Water + sanitary upgrades
  • Driveway + parking layout
  • Permit drawings
  • Construction coordination

How It Works

  1. Send us the lotcivic address, unit count or footprint, and whether you’re holding or selling.

  2. We build the path forwardoff-site upgrades, stormwater and service tie-ins, priced early enough to inform the decision.

  3. We carry it throughpermit drawings, servicing agreement, field reviews and final acceptance.

Let’s find out how many units your lot can carry.

Send us the address and the unit count you have in mind. We’ll tell you what it triggers and what needs to happen next.

Multiplex & Infill Questions

The bylaw allowance depends on lot size, location and how the municipality has implemented SSMUH. What the lot can carry is a separate question. Servicing capacity, setbacks, driveway access and parking usually cap the number below what the zoning permits.

It requires municipalities to permit small-scale multi-unit housing on lots that were previously single-family. Each municipality implemented it differently, so the allowance on the Sunshine Coast isn’t the same as Squamish or West Vancouver. We check the local bylaw, not the provincial headline.

Off-site upgrades on a street that wasn’t built for the density, stormwater retention for the added impervious area, and service tie-in costs. They add up quietly, which is why feasibility comes before design on infill work.

Usually yes, and it’s civil scope that mechanical consultants don’t cover. Each connection ties into the existing main, and where the main can’t support the added demand, an off-site upgrade comes with it.

Underground, typically, in a detention tank or rock pit sized to offset the impervious area you’re adding. There’s no room for a pond on an infill lot, but the performance requirement is the same.

That’s the feasibility scope, and it’s the most common way developers use us. We check whether the lot carries the density and price the likely upgrades closely enough to inform the purchase decision.

Often the binding constraint on a tight lot. Driveway geometry, turnaround and parking counts all have to satisfy the zoning bylaw at the same time, so we test several layouts against the requirement before locking a design.
