Horsham District Council has determined 240 affordable homes need to be built in the district every year to ease the pressure on its housing waiting list.
Cabinet member for living and working communities Ian Howard presented the new Housing Strategy for 2013-15 to the Cabinet last week.
He said that under this plan, the threshold for which developers have to provide affordable homes would be lowered from 16 to five units.
The council has also set out the mix of rented, shared ownership and retirement homes, the district needs as well as the sizes it needs.
Non-cabinet members attending the meeting welcomed the additions to planning policy, but urged that the council acts on them.
Leader of the Liberal Democrat group David Holmes (Horsham Park) said: “It’s good we know what we need and it’s also broken down into sizes. Quite clearly we have got to make sure we deliver the houses to meet the need.”
John Chidlow (Con, Southwater) said: “We need to be hard nosed with developers. Let’s be tough about this 40 per cent.”
Mr Howard (Con, Southwater) said: “We are very tough with developers and our officers work very hard to get as many affordable homes as possible as we can.”
Having been agreed by cabinet last week, the Housing Strategy 2013-15 is expected to be approved at the full council meeting on February 13.
