Union City does not appear in the federal flood insurance program community status book for Hudson County, which lists Bayonne, East Newark, Guttenberg, Harrison, Hoboken, Jersey City, Kearny, North Bergen, Secaucus, Weehawken and West New York. No paid flood insurance claim in the county file is attributed to a Union City community number.

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.

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.

What a Union City report has to prove, and to whom
In this city the report is the product, because the person who finds the mold is rarely the person who can fix it. Union City fits 66,463 residents onto 1.287 square miles, about 51,600 people per square mile, and 20,818 of its 25,725 occupied homes are rentals, the highest renter share of the ten towns we cover. Walls, risers and stacks are shared, so the finding that actually moves things is not that the wall is wet but which side of it the water is on, when it started, and who was told.
What a Union City tenant should have in hand before pushing
Sequence the paperwork or the remedy will not hold. Before repair and deduct or a rent abatement is available in New Jersey, three things must be true: the defect is in a vital facility, you did not cause it, and the landlord was notified and given adequate time to act. The state advises putting that notice in writing and sending it by a mail service that returns a receipt, so send it before you spend anything and attach the report to it. Count the units too, because three or more rental units means the building is registered with the state Bureau of Housing Inspection and that is where the complaint goes, while one and two unit buildings sit with the municipality instead.
Which side of the party wall the water is on
In attached buildings at this density the source is often the next unit or the stack. The report has to say so to be worth anything.
How many rental units are in the building
Three or more and the state Bureau of Housing Inspection is the enforcement route. One or two and it is the municipality.
Whether the notice has been sent properly
Written, dated, and sent by a service that returns a receipt. Without it the remedies do not open.
Need the wall on paper, with a date on it?
Send what you can see and when you first raised it. We will say what an independent report should record.
What happens after a Union City report lands
What Union City tenants ask before paying for an inspection
My landlord says it is condensation and my fault. Can a report settle that?
It can put the argument on paper, which is what the remedies run on. An independent assessment records the moisture readings, the area, the dates and the likely source, and it comes from a company with nothing to gain from the repair. Add the written notice you sent and the date it went, and you have the two things every New Jersey remedy asks for first.
Nobody has ever flooded here. Does that make a damp wall less serious?
It makes the cause easier to find, not less serious. Union City does not appear in the federal flood insurance community list for Hudson County and no paid claim in the county file is attributed to it, so a wet wall here is a building defect: a failed lateral, a leak in another unit, rain running downhill, or condensation. Each of those has an owner, and naming the right one is the point of the visit.
Send the floor, the wall and the date
We will tell you whether this is worth a visit and who in the building it should be addressed to.
