Siding Repair & Replacement in Passaic, NJ
84.6% of Passaic's housing is attached or multi-unit. Which clause covers your building is the first question, not the last.
Passaic is a former textile-mill city of roughly 69,600 people packed into 3.24 square miles at over 21,000 people per square mile, and its housing reflects that: of 21,019 units, only 15.0% are single-family detached. 84.6% is attached or multi-unit, and 56.7% of the whole stock was built in 1939 or earlier.
For siding that combination is unusual and it matters. Most of the walls here are pre-war frame construction that has been re-clad at least once, and a large share of the buildings are big enough to fall outside the state's siding exemption entirely. We establish which before we price anything.
In a city this multi-family, the exemption often does not apply
New Jersey's siding rule is generous and most homeowners have never heard it: N.J.A.C. 5:23-2.7(c)1xi makes repair or replacement of existing siding on one- and two-family dwellings ordinary maintenance — no permit, no inspection, no notice — and it does not require the building to be detached. The City publishes the NJ DCA's own ordinary-maintenance reference sheet on its Code Enforcement and Zoning page, so this is not a reading we invented.
But Passaic is only 15.0% single-family detached. A very large share of the city sits in buildings of three units or more, and those are outside that clause. What governs them is (c)1xii — like-material replacement up to 25% of total exterior wall area, and a permit past that. On a mill-city three- or four-family, a full re-side is comfortably past it.
So on a Passaic job the first thing we settle is the unit count and the scope percentage, and we file when the answer says to. The Construction office is at 330 Passaic Street.
Pre-war frame, re-clad in layers
With 56.7% of Passaic's stock built before 1940 and only about 20.1% built between 1950 and 1979, the aluminum here is mostly a retrofit over older wood rather than an original cladding — which is a different situation from the postwar suburbs a few miles north. Expect layers, and expect the substrate to be the real question.
On a pre-war frame wall the sheathing and the sill are what decide the job. We open a corner and look before quoting, because a wall that has held two layers of cladding for fifty years sometimes has rot at the bottom course that nobody can see from the street.
- Original wood clapboard and cedar shingle under later layers on the 56.7% pre-1940 stock
- Asbestos-cement shingle as an early over-clad, typical of pre-1940 mill-city housing
- Aluminum as a mid-century retrofit rather than original cladding
- Vinyl as the current outer layer on much of the re-clad stock
- Brick and stucco on masonry rowhouses, mixed-use buildings and the larger apartment stock

Two mill districts, and they are narrow
Passaic has exactly two historic districts on the New Jersey and National Registers — the Botany Worsted Mills district and the Dundee Canal Industrial district. They are industrial, they are geographically tight, and the overwhelming majority of the city's residential addresses sit outside both.
We check whether your address falls inside before quoting rather than assuming either way. For most Passaic homeowners the answer is that no historic review applies at all.
The river border drives the storm work
The City's adopted 2023 Aging-Friendly Land Use Plan states plainly that Passaic is bounded by the Passaic River along its eastern border, resulting in significant exposure to flood hazards. The Dundee section along the river filled in first and sits closest to that exposure.
Siding is often storm work here, and on a flood-mapped property a repair can pull in review that a routine re-side never touches. We raise it before the quote.
Common questions
My building has four apartments. Do I need a permit to re-side it?
Probably yes, and this is the most common permit question in Passaic because only 15.0% of the city's housing is single-family detached. The state exemption at N.J.A.C. 5:23-2.7(c)1xi covers one- and two-family dwellings only. A four-unit building falls under (c)1xii instead, which treats like-material replacement as ordinary maintenance only up to 25% of the building's total exterior wall area. A full re-side is past that, so it needs a permit through the Construction office at 330 Passaic Street. We establish the unit count and the scope percentage before ordering.
I have a two-family that shares a wall with next door. Am I exempt?
Yes. This trips people up because the roofing exemption one clause earlier is written for detached dwellings only — but the siding clause at (c)1xi says one- and two-family dwellings and drops the word entirely. The contrast is in the text of the rule itself. An attached two-family in Passaic can be re-sided as ordinary maintenance: no permit, no inspection, no notice. Polypropylene siding is the exception, and structural repair found during tear-off is its own question.
Is my house in a historic district?
Almost certainly not. Passaic has only two districts on the New Jersey and National Registers — Botany Worsted Mills and the Dundee Canal Industrial district — and both are industrial and geographically narrow. The great majority of residential addresses in the city sit outside them. We confirm your specific address before quoting rather than assuming.
Where do I reach the Passaic building department?
Passaic Construction / Code Enforcement, 330 Passaic Street — (973) 365-5521. Most like-for-like siding work needs no permit at all under N.J.A.C. 5:23-2.7(c)1xi, so for most jobs you will not need them. On a three-or-more-unit building we work out the wall-area percentage first. NJHIC #13VH13970900.
