Hashmonaim is located two kilometers east of Modi'in-Maccabim-Re'ut, midway between Jerusalem and Tel Aviv and is part of the Mateh Binyamin Regional Council.

[2] According to ARIJ, Israel confiscated land from several Palestinian villages/towns nearby in order to construct Hashmonaim: Under Israeli legal rulings, this territory was claimed as unoccupied state land by the prior sovereign entity, the Hashemite Kingdom of Jordan, and thus passed to the subsequent sovereign entity in occupation, the state of Israel.

A dedication ceremony on June 12, 1984, was attended by Prime Minister Yitzhak Shamir and the Sephardi chief rabbi Mordechai Eliyahu.

The community also has a clubhouse for young people, a separate Bnei Akiva branch, two basketball courts, a baseball field, playgrounds, a library and a fitness center.

[12] The drive from Hashmoniam to Jerusalem, Tel Aviv, Petah Tikva and Ariel, is approximately thirty minutes by car.
