Islington Council has adopted pioneering new planning measures that require new homes in the borough to be regularly occupied in a bid to stop the rise of so-called "buy-to-leave" properties.
In recent years there have been concerns that a significant amount of new homes in Islington, as in other parts of London, are sold off-plan to investors, some of whom then leave the properties empty as investments.
This practice, commonly referred to as "buy-to-leave", means the new housing is in effect "wasted supply" that does not help Islington meet its housing need or offer people a place to live.
Islington Council's executive agreed to adopt a new supplementary planning document (SPD) to prevent wasted housing supply.
The new SPD will put an obligation on the owners of new homes not to leave their properties empty for longer than three months.
If a property is lived in for less than two weeks every three months the council could take action including ultimately seeking an injunction from the High Court against the owner.
