Hingham residents are being asked to share their input on a number of proposals slated for the April 27 Town Meeting, including one that would make it easier for an elderly family member, or perhaps an au pair or nurse, to live on a property apart from the primary residence. There is currently no such provision, and homeowners have had to convert to two-family residences in some cases, said Mary Savage-Dunham, the town’s director of community planning. She said the Planning Board on Monday opened the public hearings on a number of topics and set dates for further discussions. The dates and topics are Monday at 7 p.m, building height exceptions, and 7:45 p.m., special permit parking determinations; Jan. 21 at 7 p.m., the accessory dwelling units proposal, and 8:30 p.m., changes to nonconforming accessory structures; Jan. 26 at 7 p.m., multi-unit housing modifications, and 8 p.m., commercial building setback requirements; Feb. 2 at 8:30 p.m., uniformity amendments designed to make the bylaws more consistent in their treatment of properties, and 9:30 p.m., the assessment of the completeness of multi-unit developments; Feb. 3 at 7:45 p.m., personal wireless services, and at the end of the meeting, housing and accessory buildings. All hearings will be held in Town Hall.
