(Representational image: DC) Hyderabad: Despite revoking around 30 per cent of applications under TS-bPASS (TS Building Permission Approval and Self-Certification System), urban local bodies, including the GHMC and the HMDA are not refunding the requisite amounts. Further, there is also delay in processing applications, often extending to more than three months beyond the stipulated time. The state government passed the TS-bPASS Act 2020 to simplify building permissions under three categories. Under it, instant registrations are granted for individual residential buildings of plot sizes up to 75 sq. yards and building height up to 7 metres. Instant approvals are available for individual residential buildings of plot size above 75 sq. yards and up to 600 sq. yards and building height up to 10 metres. There will be single-window building permissions for all residential buildings above 500 sq. metres or height above 10 metres as well as all non-residential buildings.
