Information for Building a Triplex or Fourplex

Please note: In late 2023 and spring 2024, the Province introduced housing-related legislative changes that require the City to rewrite municipal rules around zoning, development, fees and charges, and public engagement. The information on this web page may be out of date. Visit Housing Changes in Coquitlam for more information.

The Housing Choices Program was adopted in 2011, and amended in 2019, with the goal of providing new small-scale, ground-oriented housing. The Program supports a range of housing options including carriage houses, garden cottages, narrow-lot single-family homes, duplexes, triplexes, fourplexes, and multiplexes in specific areas of Southwest Coquitlam. 

These pages are for property owners who are interested in building either a triplex or a fourplex in certain areas of Southwest Coquitlam where it may be allowed. 

The current areas where it may be possible are defined in the City’s Official Community Plan as Neighbourhood Attached Residential (NAR). See the Housing Choices Areas handout for the NAR areas.
