Common Causes of Toxic or Allergenic Mold in Rental Homes, Apartments, Offices
Causes of mold or other contaminants in rental units:
This document describes common sources of toxic or allergenic mold growth in rental apartments and homes - a simple guide for renters and landlords who need to know the common sources of mold, the risk of significant hidden mold and just how extensive a hidden mold problem may be in a rental apartment or home.
I have been made aware of a leaking roof in the 2nd floor apartments so severe that requires buckets to contain. The
water, I have been told runs down the walls into the ground floor apartments where we are a tenant in one. The apartments
are known to be old and from the road I can see large blackish streaks across the light brown roofing.

Possible causes of apartment mold, possible extent of mold
What steps the tenant has already taken to deal with suspected mold contamination
I've just bought two HEPA filters for the bedroom and living room which has seemed to make a significant difference in
the severity of the congestion. Also, I have been told that the air conditioning and heat is run on a water coil system
(the air is circulated through all of the apartments) which happens to be in our bedroom closet. when I removed the vent
to put a filter in I found mold covering the back of the metal slats in vent cover. I cleaned it with bleach.
Tenant Wants to Move out of Moldy Apartment - Lease Breaking Issues
I need to move because I cannot live with this building-related sickness. It is important to know what I'm dealing with
before I go to management, because it seems to be such a severe structural issue, they may try to do something
underhanded and cover it up.
I have a year lease and need to handle the situation in a way that will allow me get out from under this situation without our being taken advantage of and we are no expert in these matters.
Compromised autoimmune system increases health risks for tenant in moldy apartment
Also I have some sort of autoimmune condition(Lupus, MS they haven't pinned it down) we are no longer able to do what I
went to school for. Our fine motor skills are compromised (and I have slight tremor).

The critique included in that article raises compelling questions about IgG testing assays, which prompts our interest in actually screening for the presence of high levels of particles that could carry allergens - dog dander or cat dander in the case at hand.
