Section 5. Every housing and redevelopment authority shall be managed, controlled and governed by five members, appointed or elected as provided in this section, of whom three shall constitute a quorum. Every member of a housing or redevelopment authority shall be a fiduciary of the housing or redevelopment authority.

In a city, four members of a housing or redevelopment authority shall be appointed by the mayor subject to confirmation by the city council; provided, that, the members shall be appointed to serve for initial terms of one, two, four and five years, respectively.

In a town, 3 members shall be elected by the town; provided, that of the members originally elected at an annual town meeting, the one receiving the highest number of votes shall serve for five years, the one receiving the next highest number of votes, for four years and the one receiving the next highest number of votes, for two years; provided, that upon the initial organization of a housing or redevelopment authority, if a town so votes at an annual or special town meeting called for the purpose, four members of such an authority shall be appointed forthwith by the selectmen to serve only until the qualification of their successors, who shall be elected at the next annual town meeting as provided above.

In a city or town, one member of a housing or redevelopment authority shall be appointed by the department for an initial term of three years. If the department does not fill a vacancy in the position of that member within 120 days from the date that the vacancy is created, the board of selectmen shall appoint, in writing, a person by a majority vote to fill such vacancy for the unexpired term. In a city, the mayor shall appoint a person subject to confirmation by the city council for the unexpired term.

Thereafter, as the term of a member of any housing or redevelopment authority expires, his successor shall be appointed or elected, in the same manner and by the same body, for a term of five years from such expiration. Membership in a housing or redevelopment authority shall be restricted to residents of the city or town.

In a city, one of the four members of a housing authority appointed by the mayor shall be a resident of that city and shall be a representative of organized labor who shall be appointed by the mayor from a list of not less than two nor more than five names, representing different unions submitted by the Central Labor Council, AFL–CIO and the International Brotherhood of Teamsters, Chauffeurs, Warehousemen and Helpers of America of the city or of the district within which the city is included. If no such list of names is submitted within sixty days after a vacancy occurs, the mayor may appoint any representative of organized labor of his own choosing to the authority. In a city, one of the four members of a housing authority appointed by the mayor shall be a tenant in a building owned and operated by or on behalf of the local housing authority who shall be appointed by the mayor from lists of names submitted by each duly recognized city-wide and project-wide tenants' organization in the city. A tenants' organization may submit a list which contains not less than two nor more than five names to the mayor who shall make his selection from among the names so submitted; provided that, where no public housing units are owned and operated by the local housing authority and no such units are owned and operated on behalf of the local housing authority, the mayor shall appoint any tenant of the housing authority from lists submitted in accordance with this section. If no list of names is submitted within sixty days after a vacancy occurs, the mayor shall appoint any tenant of his choosing to the authority. The mayor shall notify in writing tenant organizations as specified herein not less than ninety days prior to the expiration of the term of a tenant member. Whenever a vacancy occurs in the term of a tenant member for any reason other than the expiration of a term, the mayor shall notify in writing the tenant organizations specified herein within ten working days after the vacancy occurs. The mayor shall make an appointment within a reasonable time after the expiration of sixty days after said notice.

Vacancies, other than by reason of expiration of terms, shall be filled for the balance of the unexpired term, in the same manner and by the same body, except elected members in towns whose terms shall be filled in accordance with the provisions of section eleven of chapter forty-one. Every member, unless sooner removed, shall serve until the qualification of his successor.

As soon as possible after the qualification of the members of a housing or redevelopment authority the city or town clerk, as the case may be, shall file a certificate of such appointment, or of such appointment and election, as the case may be, with the department, and a duplicate thereof, in either case, in the office of the state secretary. If the state secretary finds that the housing or redevelopment authority has been organized and the members thereof elected or appointed according to law, he shall issue to it a certificate of organization and such certificate shall be conclusive evidence of the lawful organization of the authority and of the election or appointment of the members thereof.

Whenever the membership of an authority is changed by appointment, election, resignation or removal, a certificate and duplicate certificate to that effect shall be promptly so filed. A certificate so filed shall be conclusive evidence of the change in membership of the authority referred to therein.
