New residential developments built outside of the town centre will be required to provide a minimum 50% affordable housing.
From 1 April, council policy will state that half of all the bedrooms where there are 10 or more homes are in affordable housing units.
The minimum level is currently 30% but the local plan policy allows this to be reviewed each year in response to market changes.
Developments within the town centre that offer less than 50% affordable housing will have to justify this by undertaking a viability assessment.
The policy will apply to all future planning applications until the next review in April 2016.
“We are passionate about increasing the amount of affordable homes in Croydon.
“Like other London boroughs, we are in the midst of an ongoing housing crisis which is denying families a decent home to live in.
“We want to make it easier for Croydon residents to rent or buy a home which is why we have a flexible housing policy that can respond quickly to changing market conditions.”
Councillor Alison Butler, deputy leader and cabinet member for homes and regeneration
The new affordable housing quota is to be agreed as part of the Croydon Monitoring Report.
