Brighton could become the first city in England to ban second homes.
New rules, which would ban any new-build properties from becoming second homes of holiday lets, are set to be drafted after a vote by councillors.
The proposals would apply to hotspots in Brighton & Hove that the city council says have been affected in particular by the housing crisis.
If the Green-led council goes ahead with the move, it would become by far the biggest settlement to impose such a ban.
The policy of applying covenants to new build homes requiring them to remain primary residences was pioneered by the fishing town of St Ives, Cornwall in 2016 which followed a referendum.
