The notification warns that failure to do so could lead to criminal proceedings, said the TCP department.
However, with January 26 being a government holiday and if one takes into account the weekends, applications have just over a fortnight to apply for change of zone.
The TCP department said that it has completed a survey and identified illegal development in orchard land, indicating that defaulters will not be able to slip below the radar.
Failure by owners of those plots will result in the TCP department filing an FIR and if convicted, the owners of the plots can be fined Rs 10 lakh or one month imprisonment or both.
Earlier in December, the TCP board headed by TCP minister Vijai Sardesai had announced that applicants have till January 26 to apply for change of zoning but the official notification was released only on Saturday.
“All those land owners and developers who have developed their land into non-agricultural plots in non-conforming land use zones and also purchasers of such plots are hereby advised to apply for change of zone under said Section 16B of the TCP Act latest by January 26 for appropriate decision, failing which they shall attract penal action under relevant provisions of the Act,” said chief town planner Rajesh Naik in a public notice.
