Pre-rental housing quality inspection using certain technical means and methods, through the existing housing quality (rather than the quality of the project under construction), especially the structural quality of the inspection and determination, the implementation of dynamic monitoring, in order to play a safeguard the safety of people's lives and property, and to promote the full and rational use of existing housing resources to ensure the stability of the community, and therefore has a huge social and economic benefits. Pre-rental housing quality inspection by qualified testing units to test the quality of housing, assessment, and the process of issuing reports.

First, the scope of application of quality inspection:

Housing quality inspection work includes the internal structure of the house inspection and façade settlement and tilt detection, of course, the causes of housing quality problems are diversified, such as housing design, housing construction, housing construction process, such as the performance of materials and other factors. Has been built to use the house for some reason and not be able to handle the house a complete set of completion and acceptance procedures, or housing, although the original information is complete, due to certain factors on the part of the owners of both housing is not accepted by the competent authorities that are sold to the outside world that is to be delivered to the use of the house.

This kind of housing without housing acceptance of completion of the housing has been delivered for use, but later for the proof of ownership of housing that is the real estate license or need to be strictly in accordance with the requirements of the relevant units of the entire housing structure for housing safety testing and appraisal, the submission of housing structural safety inspection report, proving that the use of housing without structural safety hazards, through the issuance of the real estate license.
