Development Plans

The Department of Building and Safety issues permits for the construction, remodeling, and repair of buildings and structures in the City of Los Angeles. Permits are categorized into building permits, electrical permits, and mechanical permits (which include plumbing, HVAC systems, fire sprinklers, elevators, and pressure vessels). Depending on the complexity of a project, a permit may be issued the same day with Express Permit or e-Permit ("No Plan Check" category), or a permit may require that the plans be reviewed ("Plan Check" category) by a Building and Safety Plan Check personnel.洛杉矶市建筑安全局（Department of Building and Safety）负责为洛杉矶市内的建筑及构筑物的新建、改建与修缮作业核发许可。该类许可分为建筑许可、电气许可与机械许可三大类，其中机械许可涵盖管道系统、暖通空调（HVAC）系统、消防喷淋系统、电梯及压力容器。根据项目复杂程度的差异，许可核发可分为两种模式：一是通过快速许可（Express Permit）或电子许可（e-Permit，即“无需图纸审查（No Plan Check）”类别）当日完成核发；二是需由建筑安全局图纸审查专员对施工图纸进行审查（即“图纸审查（Plan Check）”类别）后方可核发许可。
