What is the SSMUH status in Port Coquitlam?

Port Coquitlam's SSMUH regulations are active under Zoning Bylaw No. 3630 (2008), as amended. Initial SSMUH amendments were adopted in June 2024, with further bylaw amendments adopted on June 23, 2025 to support implementation. RS-zoned properties (RS1-RS4) are eligible for 3-6 units depending on lot size and transit proximity. SSMUH is prohibited on RS-zoned lots within designated Transit Oriented Areas, which follow separate rules.

How many units can I build in Port Coquitlam under SSMUH?

In Port Coquitlam, RS-zoned lots of 280 m2 or smaller allow up to 3 units. Lots exceeding 280 m2 outside 400 m of frequent transit allow 4 units. Lots over 280 m2 within 400 m of a frequent bus stop (typically along Lougheed Highway) allow up to 6 units. Lots over 4,050 m2 are excluded. Note that SSMUH units are prohibited on RS-zoned properties within designated Transit Oriented Areas, which are subject to different density rules.

What are Port Coquitlam's RS zone lot sizes for subdivision?

Port Coquitlam has four RS zones with different subdivision standards: RS1 requires 500 m2 minimum lot area with 15 m width, RS2 requires 375 m2 with 12 m width, RS3 requires 4,000 m2 with 30 m width, and RS4 requires 300 m2 minimum with 9.5 m width.

What is the maximum ADU size in Port Coquitlam?

The maximum accessory dwelling unit (ADU) size in Port Coquitlam is 90 m2 (968 sq ft). ADU height is limited to 7.5-8.5 m depending on roof slope, with a maximum of 2 storeys. Each ADU requires 1 independently accessible parking space.

Bill 44 Active — Updated March 2026

Port Coquitlam SSMUH Multiplex & Gentle Density Guide

Port Coquitlam's RS-zoned properties now allow 3 to 6 dwelling units depending on lot size and transit proximity. Following initial SSMUH amendments in June 2024, Council adopted further bylaw amendments on June 23, 2025 to support implementation. New duplexes, triplexes, and ADUs require an SSMUH Development Permit before a building permit can be issued. With three Transit Oriented Areas and a housing target of 2,279 net new units by 2029, PoCo is one of the Tri-Cities' strongest markets for missing middle development.

Port Coquitlam's SSMUH Framework

Port Coquitlam's SSMUH regulations operate under the city's Zoning Bylaw No. 3630 (2008), as amended to comply with BC's Bill 44 Small-Scale Multi-Unit Housing legislation. The initial SSMUH amendments were adopted in June 2024, with parking regulation changes under Bylaw No. 4375 following concurrently.

On June 23, 2025, Council adopted further bylaw amendments to the Zoning Bylaw and Subdivision Servicing Bylaw No. 2241 to support SSMUH implementation. The RS1, RS2, RS3, and RS4 zones now permit small-scale multi-unit housing on eligible lots under 4,050 m2. Port Coquitlam's housing target under the provincial framework is 2,279 net new units by July 31, 2029.

Important: SSMUH units are prohibited on RS-zoned properties that fall within designated Transit Oriented Areas. Those properties follow separate, typically higher-density zoning rules. Additionally, new duplexes, developments with 3 or more dwellings, or ADUs require an SSMUH Development Permit before a building permit can be issued.

Up to 3 units

Applies to all eligible RS1-RS4 zoned lots under this size threshold.

Lots over 280 m2 — outside transit

Up to 4 units

Standard allowance for larger lots not within 400 m of a frequent bus stop.

Lots over 280 m2 — within 400 m of frequent transit

Up to 6 units

Triplex plus secondary suites. Lot must be within 400 m of frequent bus service, typically along Lougheed Highway.

Port Coquitlam RS Zone Subdivision Standards

SSMUH applies across four RS zones in Port Coquitlam, each with distinct minimum lot sizes and frontage requirements. Understanding your zone determines subdivision potential and unit configurations.

Zone	Min Lot Area	Min Width	Description
RS1	500 m2	15 m	Standard single-family residential
RS2	375 m2	12 m	Compact single-family residential
RS3	4,000 m2	30 m	Large-lot residential
RS4	300 m2	9.5 m	Small-lot residential

Exclusions & Special Considerations

SSMUH units are prohibited on RS-zoned properties within designated Transit Oriented Areas (separate density rules apply)
Lots greater than 4,050 m2 are excluded from SSMUH eligibility
RS3 zone (4,000 m2 minimum, 30 m width) — large-lot properties with distinct development potential
Hazard lands, heritage properties, and sites without municipal water/sewer may be subject to additional restrictions

Transit Oriented Areas (TOAs) in Port Coquitlam

Three Transit Oriented Areas influence development in Port Coquitlam. Within TOAs, parking minimums are eliminated and separate density rules apply that are typically more permissive than SSMUH.

Key distinction: SSMUH units are prohibited on RS-zoned properties within designated Transit Oriented Areas. If your lot falls within a TOA, it follows the TOA's own zoning and density framework rather than the SSMUH rules described on this page. Confirm your lot's status with Port Coquitlam Planning.

Category 1 TOA

Coquitlam Central Station

SkyTrain station with frequent transit connections. Highest density allowances.

Category 1 TOA

Lincoln Station

SkyTrain station. Category 1 designation enables maximum unit counts and eliminated parking.

Category 2 TOA

Port Coquitlam WCE Station

West Coast Express commuter rail station. Category 2 designation with transit-oriented density bonuses.

SSMUH Development Permit Requirement

All new duplexes, developments with 3 or more dwellings, and accessory dwelling units require an SSMUH Development Permit before a building permit can be issued. This applies to projects on RS-zoned lots outside of designated Transit Oriented Areas.

Housing forms you can build

Port Coquitlam's SSMUH framework supports multiple gentle density housing types across RS zones. Combine configurations to maximize unit count and development potential based on your lot size and transit proximity.

Duplexes with secondary suites

Two principal units with the ability to add secondary suites. FSR of approximately 0.75 for duplex configurations.

Triplexes (up to 6 units near transit)

Three principal units plus secondary suites on lots within 400 m of frequent transit, reaching up to 6 dwelling units total with 1.00 FSR.

Fourplexes

Four units on lots over 280 m2 outside transit areas. A balanced approach to gentle density in standard residential neighborhoods.

Accessory dwelling units (ADUs)

Up to 90 m2 (968 sq ft), max 2 storeys, height 7.5-8.5 m depending on roof slope. Requires 1 independently accessible parking space.

Key regulations snapshot

These baseline standards guide envelope design for SSMUH projects in Port Coquitlam. Confirm current limits with the Planning Department before submitting drawings.

Floor Space Ratio (FSR)

Approximately 0.70 FSR for 3-unit developments, 0.75 FSR for duplexes, and up to 1.00 FSR for triplex/6-unit configurations near transit.

Building Height

Pre-SSMUH: 7.5 m (up to 9.0 m with steep roof pitch). Under SSMUH: up to 11.0 m and 3 storeys for multiplex development.

ADU Height & Size

ADU height ranges 7.5-8.5 m depending on roof slope, maximum 2 storeys. Maximum floor area is 90 m2 (968 sq ft).

Maximum Building Depth

18.0 m maximum building depth applies across RS zones to maintain rear yard amenity space.

Setbacks & Coverage

Front yard: 4.0-6.0 m (reduced if lane/transit)
Side yard: 1.2-1.8 m
Max building depth: 18.0 m
Lot coverage: 45-50%

Parking Requirements

Getting Started with Port Coquitlam SSMUH

Before beginning your Port Coquitlam SSMUH project, address these key considerations:

Confirm your lot's RS zone (RS1, RS2, RS3, or RS4) and applicable subdivision standards.
Determine proximity to frequent transit stops — lots within 400 m qualify for 6 units and zero parking.
Check whether your property falls within a designated Transit Oriented Area — SSMUH is prohibited within TOAs (different rules apply).
Plan for the SSMUH Development Permit process, which must be completed before you can apply for a building permit.
Review site-specific constraints including easements, environmental considerations, and servicing requirements.
Confirm ADU requirements: 90 m2 max size, 1 independently accessible parking space.
Watch for 2026 policy updates — City staff are reviewing rules for townhouses, rowhouses, and intensive small-scale residential development.
