Residents (who are sometimes called Levittowners) were first expected to comply with a lengthy list of rules and regulations regarding the upkeep of their homes and use of their property. Two of these "rules" included a prohibition on hanging laundry out to dry on Sunday and not allowing homeowners to fence off their yards. These proved unenforceable over time, particularly when backyard pools became financially accessible to the working class and privacy concerns drove many to fence off their yards. In the years since Levitt & Sons ended construction, three- and four-story "garden apartments" and a number of non-Levitt owner-occupied houses have been built in Levittown.
