Conn. Agencies Regs. § 8-84-2
(k) Each permanent loan, the proceeds of which are to be disbursed during the construction of a dwelling on the mortgaged premises, shall provide that the construction shall be completed within eight months from the date of the loan.
(l) No construction loan shall be made unless and until the federal housing commissioner has issued a conditional commitment for mortgage insurance on a permanent loan, provided a construction loan may be made to an eligible buyer who is a veteran of World War II on issuance of a certificate of reasonable value and on a prior approval or automatic basis as determined by the public works commissioner. In no event shall the aggregate of the disbursements made under a construction loan prior to the issuance of a final compliance inspection report by the federal housing commissioner or the administrator of veterans affairs exceed eighty per cent of the estimate of value of the mortgaged property as established by said commissioner or administrator.
