Answer:
planned unit development
Step-by-step explanation:
A planned unit development (PUD) consists of both residential units (single houses, townhouses or even condominiums) and commercial units. Generally PUDs include mostly condominiums and commercial centers.
PUD can also refers to a regulatory process which provides greater flexibility to developers (builders) so that they can include diverse types of units within a same development (residential, commercial and even industrial units in one same development).
