providing a smaller living space on -site; In certain circumstances, ADUs can make it easier for families to
provide caregiving services to aging parents or grandparents; and
WHEREAS, ADUs that are rented provide additional income opportunities for homesteaded property
owners; and
WHEREAS, ADUs are only allowed in T3-L and T4 and an amendment is necessary to widen the
