Thinking About Building a Multiplex? Here’s What You Need to Know in 2025

Urban Planning

About a year ago, weposted a video about Bill 44, or what most people know as the multiplexlegislation. If you haven’t heard of it, it’s a provincial law that basicallylets single-family and duplex zones have 3 to 4 units — and sometimes even upto 6, depending on the situation. Every city in BC had until June 30, 2024, toget it in place.

When it first launched, it made headlines andsparked a lot of interest. But after Bill 44 passed, momentum unexpectedlyslowed. By the time we covered updates last December, things had gone prettyquiet — likely due to financial realities.

Now, with more families choosingmultigenerational living, there’s renewed interest in multiplex projects.Cities are also stepping up with new grants and incentives, like Burnaby’sCommunity Benefit Bonus policy, Richmond’s $40,000 grants for affordablerentals, and Surrey’s $95 million Housing Accelerator Fund from CMHC.

As an architectural firm, it's ourresponsibility to stay on top of the latest changes. In this video, we’ll walkyou through the typical densities in common SSMUH zones across differentcities, go over parking requirements, maximum FSR, and highlight a few keythings you should know

Here’s a quick rundown of howmunicipalities across Metro Vancouver are implementing multiplex zoning:

Vancouver

  • Zoning: R1-1 allows 3–4 units outright, 6–8 conditionally
  • FSR: Up to 1.0 with 6–8 units
  • Requirements: Development Cost Levy applies (unless exempt), back-lane access, minimum lot size

Keep in mind, all projects are subject to a Development Cost Levy (DCL) unless you qualify for a waiver or exemption. Typically, only projects meeting certain affordability requirements— like 100% secured rental housing — are eligible. Most standard market multiplexes will still have to pay the DCL.

Another thing: if you’re building more than three units, the city might require a low-profile transformer, which can slow down permits

Burnaby, Maple Ridge& City of Langley

  • Units Allowed: 3–4 outright, 6 in Frequent Transit Network Areas (FTNAs)
  • FSR:  No fixed limit; based on setbacks and coverage

Parking requirements arealso reduced, and in FTNA areas, no parking is required at all. While that’s anice perk for some, it’s worth noting many people still rely on privatevehicles — and for rentals, having a parking spot can still be a key factor fortenants or family members.

Surrey, Port Coquitlam& Richmond

  • Units: 3–4 outright, 6 near FTNAs
  • FSR:  Up to 1.0 in Surrey & PoCo (limited in Richmond: 0.6 or 0.3 depending     on lot size)
  • Parking: Reduced or waived near bus stops
  • Notes: Back-lane access often required

City of North Vancouver

Still in progress, but based on their February 2025 council meeting

  • Status: Draft bylaw underway
  • Units: 3–4 allowed, 6 with conditions
  • Parking: Removed
  • Details pending on FSR

Port Moody

Port Moody took a unique approach to the multiplex update

  • Approach: Owners     choose between old rules or new SSMUH
  • FSR: Starts at 0.7 for 3 units, up to 1.0 for 6
  • Flexibility: High, depending on what path you choose

Coquitlam

Coquitlam is updating its zoning bylaws, with a target release date of June 30, 2025. According to the draft from February 2025:

  • Update Due: June 30, 2025
  • Units: 2–4
  • FSR: 0.65–0.75 depending on unit count
  • Limitations: Large minimum lot and frontage requirements

West Vancouver

Initially, West Vancouver opposed the SSMUH legislation, but the province gave them an ultimatum to implement it.

  • Initial Stance: Opposed SSMUH, now complying
  • Units: Max of 3, 4, or 6—lot-specific
  • Parking: Unclear, waived near certain stops

Township of Langley

  • Units: 3–4
  • Parking: 1 space per unit (min 2 per lot)
  • FAR: Not used; GFA rules apply for upper floors
