1. Notwithstanding any provision of section 99.050 to the contrary regarding the number of housing commissioners, in any political subdivision except those described in subsection 2 of this section, a sixth housing commissioner may be appointed. Such a commissioner may be appointed, in the same manner as other appointees pursuant to section 99.050, if the housing authority determines that such a commissioner is needed to fulfill any federal requirement stating that at least one person who receives direct assistance from the housing authority shall serve as a commissioner. Any commissioner appointed to serve as a commissioner for the purposes of meeting the requirement of having a person who is directly assisted by the housing authority shall forfeit such appointment if that person:
(1) Ceases to meet the requirements of housing commissioners pursuant to section 99.050; or
(2) Ceases receiving direct assistance from the housing authority for which he or she is a commissioner.
2. The provisions of this section shall not apply to those housing authorities:
(1) Located within a city not within a county;
(2) Located within a city with a population of over four hundred thousand inhabitants;
(3) Which are exempted, pursuant to federal law or regulation, from any federal requirement stating that at least one person who receives direct assistance from the housing authority shall serve as a commissioner.
