Whitehawk FC have been given permission to use Withdean Stadium for two years from next season.
They will play their home games there once Brighton and Hove Albion have moved to the club’s new stadium at Falmer at the end of June.
The temporary permission was granted by Brighton and Hove City Council cabinet member for culture, recreation and tourism, Councillor David Smith.
Councillor Smith emphasised that the council wanted to Withdean to return to being an athletics stadium.
But Whitehawk FC will be able to use the ground while their own – at East Brighton Park – is upgraded now that the club is in the Ryman League Division One South.
Whitehawk still need planning permission for the improvements.
Albion will continue to use Withdean for some reserves and women’s team fixtures but the club’s youth team will remain based at Sussex University.
