房屋检验师（Home inspector），简称验屋师或验房师，为具有专业工程素养及资深工程经验之房屋检验人员，提供购屋者在交屋验收阶段，标准化的专业验收流程及相关咨询服务。此举系于1976年率先由美国验屋师协会在北美推动，随后推广到世界各国。

房屋检验师主要工作为协助买卖双方于交屋阶段，针对屋况检查室内空间、厨具及卫浴设备、公共设施、建材安全、给水及排水、机电设备等。近年来因交屋而产生之纠纷甚多，房屋检验师以专业角度让购屋者了解现有的屋况，如施工品质或是否使用违法建材等。随着消费者意识的抬头，有愈来愈多的购屋者更加重视房屋的品质，进而选择专业的房屋检验师代为验屋，以避免忽略房屋的瑕疵。

A home inspection is a limited, non-invasive examination of the condition of a home, often in connection with the sale of that home. Home inspections are usually conducted by a home inspector who has the training and certifications to perform such inspections. The inspector prepares and delivers to the client a written report of findings. The client then uses the knowledge gained to make informed decisions about their pending real estate purchase. The home inspector describes the condition of the home at the time of inspection but does not guarantee future condition, efficiency, or life expectancy of systems or components.
