The Secretary of Defense or his designee is authorized to maintain and operate any housing acquired under this title and assign quarters therein to military and civilian personnel and their dependents. Appropriations for quarters allowances or appropriate allotments, and rental charges to civilian personnel, may be utilized by the military department concerned for the payment of principal, interest, and other obligations, except those of maintenance and operation, of the mortgagor corporation with respect to such housing projects. Such payments shall not exceed an average of $90 a month per housing unit and total payments for all housing so acquired shall not exceed $21,000,000 per month: Provided, That, in case of the United States Coast Guard, total payments for all housing so acquired shall not exceed $90,000 per month.

Whenever the Secretary of Defense or his designee determines that it is desirable in order to effectuate the purposes of this title, the Secretary is authorized, without regard to the civil service and classification laws, to procure, by negotiation or otherwise, the services of architects and engineers, or organizations thereof, under such arrangements as he deems desirable, but at an expense not in excess of that permissible under the schedule of fees allowed from time to time by the Secretary of Housing and Urban Development in connection with projects assisted under the United States Housing Act of 1937, as amended [42 U.S.C. 1437 et seq.]. Such services may include the development of plans, drawings and specifications for family housing under this title and other services in connection therewith: Provided, That such plans, drawings, and specifications may include the use of any project to be constructed under this subchapter of alternate materials or alternate types of construction, including prefabrication, that provide substantially equal value and conform to standards established by the Secretary of Housing and Urban Development: Provided further, That such plans, drawings, and specifications, when developed pursuant to arrangements made under this section after August 7, 1956, shall follow the principle of modular measure, in order that the housing may be built by conventional construction, on-site fabrication, factory precutting, factory fabrication, or any combination of these construction methods: Provided further, That the Secretary of Defense may designate certain sites or parts thereof for family housing to be furnished from prefabricated houses or housing components. Such arrangements may include provision for advance or progress payments, for payment by third parties, for payment by the Government of any such compensation as it not paid for by third parties, and shall include provision for reimbursement by third parties to the Government of any compensation or other expenses paid by the Government pursuant to this section, and may include other provisions for compensation. Any public works appropriations now or hereafter available to the Departments of the Army, Navy, or Air Force or the Coast Guard may be obligated by the respective departments or the Coast Guard for these purposes. Reimbursements to the Government on account of payments made pursuant to this section shall be made to appropriations against which such payments were charged. The Secretary of Defense is further authorized to advance or pay to the Department of Housing and Urban Development its “Appraisal and Eligibility Statement” fees in connection with such family housing. The Secretary of Defense is further authorized to enter into arrangements by contract or otherwise for eventual acquisition by the Government, without cost to the Government of all right, title, and interest in sites on which housing is constructed pursuant to this title and improvements thereon.

In the construction of housing under the authority of this title and title VIII of the National Housing Act, as amended [12 U.S.C. 1748 et seq.], the maximum limitations on net floor area for each unit shall be the same as the net floor area limitations prescribed by law (at the time plans and specifications for such construction are begun) for public quarters built with appropriated funds under military construction authority.
