Regulatory Support for
Multiplex Housing
Simplifying the path of duplexes, triplexes and fourplexes
Many municipalities are updating zoning rules to
encourage the development of small-scale multi-unit
housing. These changes make it easier to build duplexes,
triplexes and fourplexes without complex rezoning
processes. By allowing more units on typical residential
lots and reducing parking requirements, these policies aim
to increase housing supply, promote affordability and
support vibrant, walkable neighborhoods. Homeowners now
have more opportunities to convert or rebuild properties
into multiplexes, helping meet growing housing demand
while maintaining community character.
