Gang members will be evicted under new rules being pushed through by Hackney Homes.
The revised tenancy agreement was drawn up in response to the August riots last year.
John Calderon, former chairman of the Federation of Hackney Tenants and Residents Associations, has called it “draconian”.
The terms make gang activity a breach of the tenancy conditions.
A gang is defined in the document as a group that consists of at least three people and uses a name, emblem or colour that enables its members to be identified by others as a group, or is associated with a particular area.
But Mr Calderon said the document has not been publicised enough and many residents are not aware of its existence.
He claimed that not all tenants received a copy of the proposed agreement, which has not been revised since 2004.
Only nine per cent of tenants returned a consultation survey to Hackney Homes.
“It represents the largest shift in tenants’ relationship with the council ever but is written in legalistic language, making it difficult to understand,” said Mr Calderon.
He said it is wrong that more efforts were not made to make sure each tenant was aware of its significance.
There are also new rules about what breeds of dog tenants can keep. Pitbulls and American Staffordshire Terriers are now banned.
But there is no borough-wide elected tenants and residents organisation through which Hackney Homes can negotiate the rules with tenants.
Deputy Mayor Karen Alcock said it was was not in the interests of Hackney Homes to create fear. She said the consultation process had been extended by a month because she recognised the need to liaise with residents on important decisions.
