Our landlord has been doing construction in vacated units in the bldg, on an adjacent unit (same parcel) for a duration of approx 4 months through the year. This has been noisy (saws, power tools, large machinery), has resulted in trash and debris in shared backyard area, breached security with visiting workers, propping doors, etc., privacy intrusions (has walked in to apts unannounced, workers walking along scaffolding for a month), and we have concerns about fumes, dust, other airborne pollutants in the area. Vacated units when overturned rent increased by upwards of 50%. This fall we received a rent increase notice this time in order of 13% (last fall 7%). At this point we've lost patience with giving way to construction. Might we have breach of CQE here?
