The term "total voting interest" is often used in the context of condominium and cooperative associations laws when providing rules for the votes necessary to take collective action, such as an amendment of the bylaws of the governing association or to address an item at a board meeting of the association. Each association defines the voting rights of its members, but typically there is one voting interest per lot or parcel.
The folowing is an example of a state law dealing with total voting interests:
" Notwithstanding the provisions of chapter 633 or of any other code, statute, ordinance, administrative rule, or regulation, or any interpretation thereof, a cooperative or unit owner is not obligated to retrofit the common elements or units of a residential cooperative that meets the definition of "housing for older persons" in s. 760.29(4)(b)3. to comply with requirements relating to handrails and guardrails in a building that has been certified for occupancy by the applicable governmental entity, if the unit owners have voted to forego such retrofitting by the affirmative vote of two-thirds of all voting interests in the affected cooperative. However, a cooperative may not forego the retrofitting in common areas in a high-rise building. For purposes of this subsection, the term "high-rise building" means a building that is greater than 75 feet in height where the building height is measured from the lowest level of fire department access to the floor of the highest occupiable story. For purposes of this subsection, the term "common areas" means stairwells and exposed, outdoor walkways and corridors. In no event shall the local authority having jurisdiction require completion of retrofitting of common areas with handrails and guardrails before the end of 2014. "
