Former President Park Geun-hye left the presidential complex of Cheong Wa Dae on Sunday, two days after the Constitutional Court upheld her impeachment.
Ending some four years' stay in the presidential mansion, Park headed back to her private residence in Samseong neighbourhood, southern Seoul, Yonhap news agency reported.
Hundreds of supporters were waiting for her arrival at home, chanting "Park Geu-hye, the President!" and "Cancel the impeachment!"
The Constitutional Court upheld on Friday Park's impeachment over a corruption scandal.
But she had stayed on in the presidential complex while keeping silent on the ruling, prompting rivals to criticise her for behaving as if she won't accept the result.
As rumours of Park's possible early return spread in the afternoon, hundreds of her supporters gathered in front of her private house, where she lived from 1990 to 2013 before moving into the presidential office.
A some 1,000-strong police force was deployed around the house to prevent possible violence.
Park's aides said the repair work of her house began immediately after the court ruling on Friday.
The residential boiler at her home was fixed and other home furnishings, such as wallpaper, were being prepared on Sunday.
A space where her security guards can stay is being created inside the residence, according to other sources.
