Harrison Mold Removal for New Buildings on Low Ground
Tell us which floor you are on and what the wall feels like, and we will say whether this is the building's problem or yours before anybody opens anything. Harrison's riverside half is genuinely low, with the PATH station measuring 5.2 feet against 29.1 feet in the older part of town to the north, and the 7,450 feet of levee and floodwall planned to protect the redevelopment area is authorized and still in design rather than built.

Who owns the wet wall in a Harrison apartment building
Harrison is not an old town with new buildings in it, it is a new town with an old edge, and that decides who is responsible for your damp. Its population grew 20.1 percent between 2010 and 2020, its median housing unit was built in 1990, 45.1 percent of units date from 2000 or later and 36.4 percent sit in buildings of fifty units or more. In that stock the wet wall is very unlikely to be yours. The New Jersey Condominium Act puts foundations, structural and bearing parts, main walls, roofs and basements among the common elements, and it also gives the association a right of access to a unit during reasonable hours to maintain or repair those elements, which is the lever to pull when a building is slow. Buildings of three or more units are separately registered with the Department of Community Affairs and inspected on a cycle by its Bureau of Housing Inspection, so an unrepaired leak has somewhere to go besides the managing agent. Where you sit matters as much as what you live in. Harrison's whole combined system relieves into one river: six outfalls, all permitted to the town, all discharging to the Passaic, with five active at Hamilton Avenue, Cleveland Avenue, Harrison Avenue, Middlesex Street and Worthington Avenue. The town has also put two catchments in writing as having sewers that cannot cope, the Angelo Cifeli Drive and Bergen Street drainage areas, so a basement flooding there in ordinary heavy rain is a known town condition you can cite rather than a mystery you have to prove.

Is this the building's wall, or yours?
Tell us the building and the floor. Settling who owns the wall decides who pays for it, and it is far cheaper to settle before anyone cuts into it.

The flood protection planned for Harrison's redevelopment area, known as the South 1st Street levee and flood system, is authorized at 7,450 linear feet with eight enclosures: 1,750 feet of levee averaging 6.5 feet high and 5,700 feet of floodwall averaging 6.2 feet high, running from the Jackson Street Bridge to the NJ Transit rail bridge. The annex records the design memorandum as complete, engineering and design still under way and a Limited Reevaluation Report being prepared to reaffirm the project's viability.
