While change over time is inevitable, it is important to weigh the benefits of future development against negative impacts to a community’s significant assets, and identify compromises or ways to mitigate these impacts if they are necessary. Such assets can include existing affordable housing, historic buildings, beloved neighborhoods, protecting homeowners from foreclosure, and more. At the same time, this should not be done at the absolute expense of new housing supply, as a relatively even turnover of the housing stock over time encourages diversity of age and condition, an important affordability variable  – today’s new buildings become more affordable over the following decade, and so on. An additional concern for preserving existing affordable housing is in ensuring conditions remain safe and decent.
