(

a) As a condition of the sale of property to a housing-related entity pursuant to subdivision (

c) of

Section 54239.1 or pursuant to

Section 54239.2, the housing-related entity shall provide an enforceable commitment to the selling agency that, if a construction project is undertaken on the property, and the entirety of the project is not a public work for which prevailing wages must be paid for purposes of

Chapter 1 (commencing with

Section 1720) of Part of Division of the Labor Code, all construction workers employed on the project will be paid at least the general prevailing rate of per diem wages for the type of work and geographic area, as determined by the Director of Industrial Relations pursuant to Sections and 1773.9 of the Labor Code, except that apprentices registered in programs approved by the Chief of the Division of Apprenticeship Standards may be paid at least the applicable apprentice prevailing rate. (

b) If the project is subject to subdivision (a), then for those portions of the project that are not a public work all of the following shall apply:

(1) The housing-related entity shall ensure that the prevailing wage requirement is included in all contracts for the performance of all construction work.

(2) All contractors and subcontractors shall pay to all construction workers employed in the execution of the work at least the general prevailing rate of per diem wages, except that apprentices registered in programs approved by the Chief of the Division of Apprenticeship Standards may be paid at least the applicable apprentice prevailing rate.

(3) Except as provided in paragraph (5), all contractors and subcontractors shall maintain and verify payroll records pursuant to

Section of the Labor Code and make those records available for inspection and copying as provided therein.

(4) Except as provided in paragraph (5), the obligation of the contractors and subcontractors to pay prevailing wages may be enforced by the Labor Commissioner through the issuance of a civil wage and penalty assessment pursuant to

Section of the Labor Code, which may be reviewed pursuant to

Section of the Labor Code, within months after the completion of the project, or by an underpaid worker through an administrative complaint or civil action, or by a joint labor-management committee though a civil action under

Section 1771.2 of the Labor Code. If a civil wage and penalty assessment is issued, the contractor, subcontractor, and surety on a bond or bonds issued to secure the payment of wages covered by the assessment shall be liable for liquidated damages pursuant to

Section 1742.1 of the Labor Code. (5) Paragraphs (3) and (4) shall not apply if all contractors and subcontractors performing work on the project are subject to a project labor agreement that requires the payment of prevailing wages to all construction workers employed in the execution of the project and provides for enforcement of that obligation through an arbitration procedure. For purposes of this paragraph, “project labor agreement” has the same meaning as set forth in paragraph (1) of subdivision (

b) of

Section of the Public Contract Code.

(6) Notwithstanding subdivision (

c) of

Section 1773.1 of the Labor Code, the requirement that employer payments not reduce the obligation to pay the hourly straight time or overtime wages found to be prevailing shall not apply if otherwise provided in a bona fide collective bargaining agreement covering the worker. The requirement to pay at least the general prevailing rate of per diem wages does not preclude use of an alternative workweek

schedule adopted pursuant to

Section or of the Labor Code.
