Secondary Dwelling Units

Secondary Dwelling Units (SDUs) help create a variety of housing options within our community. SDUs include secondary suites, and carriage houses. SDUs are permitted in residential zones on lots with single-family detached homes. Additional SDUs are not permitted on lots with existing SDUs, or duplexes.  Before building, you should understand the different types of SDUs allowed in our community, where they are permitted, and what you need for your building permit application.
