Rand兰德：2024洛杉矶的项目劳工协议和社会福利住房生产成本报告（英文版）

This study estimates the effects of a project labor agreement (PLA) requiring union construction labor on the production costs of publicly funded permanent supportive housing projects aimed at addressing chronic homelessness in Los Angeles. The results indicate that the PLA added 21 percent to total development costs. Additional evidence presented suggests that longer project completion time is one potential mechanism driving this cost effect.
