Allenstown, NH

In 2015, Allenstown passed Chapter 18 of its Zoning Ordinance, which governs pre-site-built housing and manufactured housing, as well as manufactured housing parks. The zoning explicitly allows manufactured homes on any lot that allows single-family homes. Manufactured home parks (where the homes are not on permanent foundations) are governed by specific provisions in this chapter, whereas pre-site-built homes clustered on permanent foundations are governed by the Town’s cluster housing provisions. Manufactured home parks can be built by Conditional Use Permit with the Manufactured Home Park Overlay District within the Open Space and Farming Zone. Parks can have one manufactured home for every two acres, and parks must be at least 15 acres in size with at least 20% of the park preserved as open space. Individual home lots have specific dimensional rules, as well.
