I've started a blog to inform renters about bad landlords and the first one posted is about 4205 7th Avenue.
The owners of this building are notorious for not returning security deposits. They will lie and deny that tenants had given a deposit even though it was required at the signing of the lease.
They've done numerous illegal construction on the building and the building itself is unsafe to live due to illegal gut work they've done in the garden level.
These owners will also enter their tenants apartments unannounced and without permission. They fight constantly and tenants will hear the shouting arguments daily from 7am until 11pm.
There is issue with lack of heat and the likelihood of the owners using their tenants electricity, essentially stealing it from their tenants.
