Because you don't graduate from a related major, you may need to study harder, but it is not impossible.
Home inspector, whose standardized name is "house inspection consultant", belongs to the third-party house quality inspector, who mainly tests the visual quality and use function of the house.
Compared with architects and builders, etc. It requires a wider range of knowledge (you should be familiar with almost all housing projects), but you are not required to be able to build a house. For example, the home inspector is a gourmet, but he can't cook. A critic, but not a writer. As a consultant, you need high consultation and communication skills. Well, you can check an article: home inspector is a gourmet, not a chef.
You are not a related major, so you definitely need training. Moreover, starting from next year, home inspector will hold relevant certificates.
The national unified training examination is undertaken by "1+N Curriculum Development Center for Housing Inspection Consultants".
I hope I can help you!
