A seasonal boat shelter which was originally placed prior to September 1, 1991 and which is visually intrusive, but is otherwise in compliance with this section, may continue to be placed seasonally until January 1, 1996. Any seasonal boat shelter placement after January 1, 1996 shall comply with this section.

Any boat shelter originally placed or permitted after September 1, 1991 may not exceed an outside dimension of 12 feet wide by 24 feet long on waters under 1000 acres in size and may not exceed an outside dimension of 14 feet wide by 24 feet long on waters 1000 acres and larger in size. The burden of proving that a boat shelter was placed prior to September 1, 1991 shall be on the owner. A seasonal boat shelter originally placed prior to September 1, 1991 and which does not comply with this subsection may not be expanded in size. NR 326.055(2)(d)(d) A boat shelter shall be connected to adjacent uplands by a pier. NR 326.055(2)(e)(e) A boat shelter may include a roof but may not include walls, sides or equivalent construction.
