Ghaziabad District has been divided into four sub-divisions for the purpose of revenue and general administration namely Ghaziabad, Hapur, Modi Nagar and Garhmukteshwar. The centrally situated tehsil of Ghaziabad has three Parganas - Loni, Dasna and Jalalabad. Hapur tehsil lies in the east of the district and has three Parganas - Hapur, Babugarh and Dhaulana. Modi Nagar tehsil has only one pargana named Jalalabad and is located in the northern part. To the north-east lies tehsil Garhmukteshwar which comprises the two Parganas - Garh and Puth.
The general administration of Ghaziabad District is vested in the district officer who holds a key post and is the pivot of the district administrative machinery. He represents the State Government and is responsible for the proper execution of all the government orders. As a Collector his main function is to ensure the collection of land revenue and other government dues as well as the proper maintenance of land records. As District Magistrate his main duty is to maintain law and order with the help of the magistracy and the police. District Magistrate is assisted by five Additional District Magistrates, four Sub-Divisional Magistrates, two Additional City Magistrates and a City Magistrate in the proper functioning of the district administration. Each tehsil has a resident Tehsildar who is assisted by a number of Naib Tehsildars.
