Mission SSMUH Multiplex & Gentle Density Guide

Mission adopted SSMUH regulations on June 30, 2024, allowing up to 4 units on serviced residential lots. SSMUH has largely shaped the forms and patterns of future infill and intensification across Mission's urban community. A separate Transit Oriented Area near the West Coast Express station enables even higher density with up to 10 storeys.

Mission's SSMUH Zoning Framework

On June 30, 2024, the District of Mission adopted SSMUH zoning amendments to the master Zoning Bylaw 5050-2009 to comply with BC's Bill 44 Small-Scale Multi-Unit Housing legislation. A companion TOA Bylaw 6292-2024 was adopted on September 9, 2024, establishing higher-density rules near the West Coast Express station.

Eligible lots must have municipal water and sanitary sewer connections. Existing R1, R2, and R3 zones are being consolidated into new R4-L and R4-S zones to simplify the residential zoning framework across the district. SSMUH has largely dictated the forms and shapes of future infill and intensification throughout Mission's urban community, with standard allowances of 3 to 4 units based on lot size.

Unit Allowances by Lot Size

Lot SizeRequirementMax Units
< 280 m2Municipal water + sanitary sewer3 units
≥ 280 m2Municipal water + sanitary sewer4 units

Lots within 400 m of the West Coast Express station are excluded from SSMUH and follow TOA rules instead. District of Mission SSMUH Page

Transit Oriented Area (TOA) Density Tiers

Properties within 400 m of the West Coast Express (WCE) station are governed by TOA Bylaw 6292-2024, adopted September 9, 2024. These lots are excluded from standard SSMUH and instead follow significantly higher-density rules organized into two tiers:

TOA TierDistance from WCE StationMax FSRMax Height
Tier 4Within 200 m3.5 FSR10 storeys
Tier 5200 - 400 m2.5 FSR6 storeys

Zone Consolidation: R1/R2/R3 to R4-L & R4-S

Mission is consolidating three existing residential zones into two new SSMUH-compliant zones under Zoning Bylaw 5050-2009:

R4-L (Large Urban Residential)

Replaces larger-lot portions of existing R1, R2, R3 zones

R4-S (Small Urban Residential)

Replaces smaller-lot portions of existing R1, R2, R3 zones

This consolidation streamlines the residential zoning framework, ensuring consistent SSMUH regulations across all eligible properties.

Draft Official Community Plan & Bill 25 Compliance

Mission has drafted a new Official Community Plan under Bylaw 6350-2025, which is currently available for public engagement. The new OCP reflects the district's evolving housing priorities, including alignment with SSMUH and TOA frameworks already in place.

Separately, the Province's Bill 25 requires municipalities to update their bylaws by June 30, 2026. Mission is actively working toward compliance with this deadline, which will further refine zoning and development regulations across the district.

  • Roof pitch bonus: +12% for pitches ≥ 7:12 (up to ~11.7 m)
  • Max 4 buildings per lot

Parking Requirements

  • Principal unit: Proposed 1.5 stalls (reduced from 2.0)
  • Accessory unit: 1.0 stall per unit
  • Tandem parking permitted
  • Garage setback: Min 3.0 m regardless of building height

Lot Coverage & Impervious Surfaces

  • Urban compact: 35% lot coverage, 50% impervious max
  • Other urban: 30% lot coverage, 50% impervious max
  • Suburban: 20% lot coverage, 30% impervious max

Housing Progress

  • 133 units completed toward 2025 annual target
  • 64% of 2025 annual target (211 units)
  • 1,798 units 5-year housing target

Water Supply Infrastructure Limitations

  • Mission has identified water supply capacity constraints in certain service areas that may limit SSMUH development
  • The District has requested a 5-year extension from the Province for areas with insufficient water infrastructure
  • All SSMUH-eligible lots must have municipal water and sanitary sewer connections
  • A minimum 6.0 m setback from undevelopable areas (e.g., slopes, watercourses) is required

Confirm servicing availability with the District before proceeding with site acquisition or design.

How VanPlex Supports Mission SSMUH Projects

Concept to Permit

We coordinate architects, engineers, and consultants to ensure your Mission SSMUH project aligns with Bylaw 5050-2009 and the new R4-L or R4-S zone requirements. From servicing confirmation to height optimization with roof pitch bonuses, we handle the regulatory complexity.

Feasibility Analysis

Comprehensive analysis of your Mission lot's SSMUH potential, including zone classification, servicing availability, TOA proximity, unit configurations, and pro forma projections accounting for lot coverage and impervious surface limits.

Request Your Mission SSMUH Feasibility

Share your Mission address to receive a tailored analysis including your SSMUH zone, unit allowance, servicing status, TOA eligibility, and development pro forma.

Getting Started with Mission SSMUH

Before beginning your Mission SSMUH project, follow these steps:

  • Confirm your lot has municipal water and sanitary sewer connections -- properties without both services are not eligible
  • Determine whether your property falls within the TOA boundary (400 m of WCE station), which triggers higher-density TOA rules instead of SSMUH
  • Check your current zone (R1, R2, or R3) and understand the transition to R4-L or R4-S under the zone consolidation
  • Review lot coverage limits (20-35%) and impervious surface maximums (30-50%) based on your area classification
  • Verify minimum 6.0 m setback from any undevelopable areas (slopes, watercourses, geotechnical hazards)
