Grmovac is a sub-neighborhood of Ugrinovci, which is 3 km away and to which it makes no urban connection, near the Belgrade-Zagreb highway and the village of Dobanovci in the neighboring municipality of Surčin.

Origins of Grmovac (Serbian for 'bushy place') date from 1996/7 when the Zemun's municipal leadership (ruled by the Serbian Radical Party and headed by Vojislav Šešelj) decided to sell empty lots on a barren meadow to the refugees from Croatia which were forced out after the Operation Storm in 1995.

Prices were low and many people bought the land (some 3,000 lots which still brought significant income to the municipality) not paying attention that the area was not designated for urban development and the lack of any infrastructure.

The total lack of infrastructure (including not just schools, ambulances or kindergartens, but such basic things like running water, grocery stores, pavement or electricity) prevented the settlement from any major growth.

Electricity was supposed to be introduced in December 2006 on a temporary basis for 6 months from 'humanitarian reasons' as the entire settlement is classified as an illegal one, but was postponed until February 2007.
