It has its seat at the Grand Hôtel d'Ajaccio et Continental, in the Corsican capital of Ajaccio.

On 2 March 1982, a law was passed that gave Corsica the status of territorial collectivity (collectivité territoriale), abolishing the Corsican Regional Council which had existed before.

Unlike the regional councils, the Corsican Assembly has executive powers over the island.

There are 63 members of the Assembly, elected for a six-year term via a closed party list and two rounds of voting.

The list that wins in the first or second round automatically obtains three seats as a "premium to the majority".
