The Department publishes notified development plans for urban complexes in Haryana (including Gurugram-Manesar, Sohna, Pataudi and Farrukhnagar where notified), CLU and licence procedures, and policies. Always confirm that a plan you are reading is the final notified version, not a draft published for objections.
