Residents facing eviction from their police-owned homes are presenting a petition to the Mayor of London, pleading with him to reverse the decision.
Public service workers living at Raynesfield, Raynes Park and 30 Griffiths Road, South Wimbledon have been told they must pack their bags before the end of the year.
But with average house prices in the area reaching £617,000 this year, they will be forced to uproot familes to find affordable housing.
Evictees were joined by councillor Andrew Judge, cabinet member for environmental sustainability and regeneration, to present the petition to Tom Copley, Labour's housing spokesman on the London Assembly, outside the GLA on Wednesday evening.
Mr Copley said: "We simply don't have enough social and affordable housing in the capital.
"The mayor wears a number of hats, one of which is his MOPAC hat and one his housing delivery and affordable housing hat.
"I think it's quite contradictory to be on the one hand responsible for the delivery of affordable housing and on the other evicting people from properties."
Mr Copley said he will present the petition to the Mayor, and is expecting a response on the issue "very soon".
A Mayor's Office for Policing and Crime (MOPAC) spokesman said: "The 30 Griffiths Road property was leased to Crown Housing on a time-limited basis and tenants were informed from the outset that it was not a long term arrangement.
"We understand that Crown Housing is working with each tenant to establish whether they have alternative accommodation that they could offer.
"MOPAC is responsible for policing and keeping the capital safe is its key priority.
"As part of MOPAC’s estate strategy we are releasing buildings which are not used for core policing and using the receipts to fund investment in frontline policing in London."
