What is a 4 Plex Multi-plex?
The 4 Plex is a multi-plex self-contained residential unit located in the backyard of a primary home. These dwellings provide privacy and independence while still being part of the same property.
Also known as granny flats, coach houses, or detached ADUs, multi-plex offer a modern solution to urban housing challenges, allowing families to live multigenerationally, homeowners to generate passive income, or professionals to create a dedicated work-from-home space.
