N.Y. General City Law § 45-a: Corporations may conduct business

§ 45-a. Corporations may conduct business. A domestic corporation

desiring or intending to conduct the trade, business or calling of a

plumber or of plumbing in a city of this state, as employing or master

plumber, may do so provided one or more officers of such corporation

separately or aggregately actually hold and own at least fifty-one per

centum of the issued and outstanding capital stock of said corporation,

and provided that each of such officers holding such percentage of the

stock is the holder of a certificate of competency of such board of the

city in which it conducts or proposes to conduct such business as

provided in section forty-five. In case one or more officers of a

corporation engaged in such business shall die, being the holder of a

certificate of competency, the corporation may continue the business

during the time necessarily required for the administration of the

estate of such deceased officer, not exceeding two years from the

granting of letters, provided one or more officers of the corporation is

the holder of a certificate of competency and together with the legal

representatives of such deceased officer or officers, actually owns and

holds at least fifty-one per centum of the issued and outstanding

capital stock of the said corporation. Each and every member of said

corporation holding a certificate of competency shall comply with all

the rules and regulations applicable to master or employing plumbers in

the locality in which the corporation is engaged in business. Such

corporation shall register as provided in section forty-six of this

chapter.
