affordable for more homebuyers.9

each reenacted and amended to read as follows:11
As used in this chapter:12

constructed to house farm implements, hay, grain, poultry, livestock, 14
or other horticultural products. This structure may not be a place of 15

are processed, treated, or packaged, nor may it be a place used by 17
the public.18
