The state of Florida requires every city to file a plan to ensure that enough affordable housing gets built. Many prosperous South Florida cities skirt the law. State reviewers don't stop them. Some cities file plans that are half-hearted. Key Biscayne's plan simply says that affordable housing requirements do not apply there.
Some cities file plans and then apparently violate their provisions.
This is common. Some pointed instead to a handful of affordable single-family homes that had been built. Plan reviewers at the state Department of Community Affairs attributed the lack of results to their lack of authority. But state reviewers do have the power to reject bad plans - for example, plans that underestimate housing needs or propose inadequate measures for affordable housing. They don't always use that power, however.
