When it comes to urban development and zoning regulations, the term "upzone" refers to the process of increasing the allowable density or height of a particular area. While "upzone" is commonly used, there are several synonymous terms that convey a similar meaning. One such term is "rezone", which denotes the act of changing the designated land use rules. Another synonym is "density bonus", which implies offering incentives or relaxing restrictions for developers who build more housing units within a given area. Moreover, "intensify" can also be used to describe the process of increasing the density or intensity of development. These synonyms all capture the concept of modifying zoning regulations to accommodate more growth and development in urban areas.
