Hudson County
Mold Removal in Union City, Where Nothing Floods
Union City is not a flood town, which is good news: a damp wall here almost always has an ordinary, findable cause, and a written report is usually what gets it fixed. No paid flood insurance claim in the county file is attributed to Union City, and the town does not appear in the federal community list for Hudson County, so the water is condensation, a failed lateral or a leak next door, and with four in five households renting the real question is who has to pay.

Who is responsible for a wet wall in a Union City rental
Union City sits at about 201 feet at Summit Avenue, the highest ground in this whole service area, and nothing tidal reaches it. It is named as a combined sewer community, yet the state inventory places no outfall inside the city at all, the nearest being down at the river in Hoboken and Weehawken, so combined flow has to travel off the ridge before it can be released and a surcharge shows up indoors rather than at a visible outfall. That leaves three real candidates for water in a basement here: rain running downhill, a failed lateral, or groundwater in the Palisades rock. Add a fourth for the upper floors, because the July dew point at Newark Liberty holds between about 62 and 64 degrees all day and any surface colder than that condenses on its own. The tenure numbers decide the rest of the conversation. Of 25,725 occupied homes, 20,818 are rentals, about 81 percent and the highest share of the ten municipalities here, in dense attached buildings where 32 percent of the stock predates 1939. If the building holds three or more rental units it is registered with the state Bureau of Housing Inspection, which is the enforcement agency for housing code violations; one and two unit buildings fall outside it and the complaint goes to the municipality instead. Either way, the Department of Health is blunt that government offices have little authority to cite an owner over mold itself, and tells renters to raise unrepaired leaks with the local building code office, which can address them as structural deficiencies. So report the leak, not the mold, put the notice in writing, and send it the way the state advises, by a mail service that returns a receipt. That letter plus an independent report is what makes repair and deduct or a rent abatement stand up later.

Union City is named by the North Hudson Sewerage Authority as one of its combined sewer communities, yet the state outfall inventory places no combined sewer outfall inside Union City itself. The nearest outfalls on that permit are in Hoboken and Weehawken, down at the river.

All New Jersey buildings with three or more rental units must comply with the regulations for the Maintenance of Hotels and Multiple Dwellings and must be registered with the state Bureau of Housing Inspection, which is the enforcement agency for housing code violations in those buildings. One and two unit buildings do not fall under the Bureau's jurisdiction and, when not owner occupied, must instead register with the municipal clerk.

The Department of Health tells renters plainly that because of the lack of mold regulations, government offices have little authority to cite building owners over mold contamination, and that renters should contact their local building code office about unrepaired building leaks, which those offices can address as structural deficiencies such as leaks and plumbing faults.

Before a New Jersey tenant may use repair and deduct, constructive eviction, rent abatement or rent withholding, three things must be true: the defect must be of a vital facility, the tenant must not have caused it, and the tenant must have notified the landlord and allowed adequate time to fix it. The state advises giving that notice in writing and sending it by a mail service that produces a return receipt.
