律师说如果房间或周围三米建了下水道就不能交换合同了,是什么意思

If the surveyor believes that the public sewer has been built over, or there is a structure within 3 meters of it, please do not allow us to exchange contracts。

请问一般什么情况会有这种问题?应该做什么调查?

你把surveyor怎么说的贴上来看看

Q:
Does the public sewer map show any public sewer within the boundary of the property?
A:
YES. The public sewer map shows a sewer within the boundary of the property. It has not always been a requirement for all public sewers to be recorded on the public sewer map. It is therefore possible for unidentified public sewers to exist within the boundary of the property.

有拓建?拓建的部分离public sewer三米之内需要自来水公司的build over agreement. 另外拓建的部分有building regulation completion certificate么。
