The rules, in plain language
What Passaic allows as of February 2026
The city amended its zoning ordinance (§ 317-16.G, Ord. 2510-26) to allow one accessory dwelling unit in 1- and 2-family homes, in every zone of the city. These are the conditions.
- 01
1- or 2-family home
3-family or larger homes don't qualify.
- 02
One unit per lot
One accessory unit, not two.
- 03
Where it can go
Attic, basement, ground floor below the main unit, or above a garage. A separate backyard cottage is not covered.
- 04
Size
At least 300 sq ft; at most half the home's living area; up to 3 bedrooms.
- 05
Basement, not cellar
If more than half of the basement is below grade, the city calls it a cellar and it doesn't qualify. We measure it on the visit.
- 06
Parking
Existing on-site parking cannot be removed.
- 07
Exterior
Same materials and colors as the main house.
- 08
Approval
It's a conditional use: the Planning Board approves it with architect-stamped plans, a site plan and a public hearing. We prepare and present everything.
- 09
20-year affordability
The unit is deed-restricted as affordable housing for 20 years: the tenant must be under an income limit and rent is capped. The numbers are alongside.
How it works
From "does it qualify?" to the keys, with one team.
- 01
Free eligibility check
Give us the address and three details. Within 48 hours: qualifies, likely, or no.
- 02
Home visit
45 minutes. We measure the space, check exits, ceiling height and parking, and give you a cost range.
- 03
Design
Plans for your unit by a NJ-licensed architect, built to the ordinance.
- 04
Planning Board
We prepare the site plan, application and neighbor notices, and present your case at the hearing.
- 05
Permits
Building, electrical and plumbing permits, plus the deed restriction. We file it all.
- 06
Build and certificate
Construction by a NJ-registered contractor, inspections, and the certificate of occupancy in your hand.
Who this is for
Three Passaic families. Three reasons.
The family that outgrew the house
Adult kids, aging parents, a relative moving in. A second unit with its own door, kitchen and bath, without selling or moving.
The basement that's already occupied
If someone already lives in your basement without a permit, every inspection is a risk. Making it legal protects your family, your insurance and your home.
The two-family owner
You know how permits work. We give you the real numbers, affordability rule included, before you sign anything.
What it costs
A clear range before you sign anything.
A basement or garage conversion with kitchen and bath in New Jersey runs $75,000 to $150,000 depending on the structure, utilities and finishes. After the visit you get a range for your home; after design, a fixed price that includes plans, permits and the build.
Frequently asked
Can I rent the unit to anyone I want?+
To anyone whose income is under the limit at a rent within the cap. A relative who qualifies by income can be the tenant.
Can I build a separate cottage in the backyard?+
Passaic's ordinance doesn't cover it. It allows attic, basement, ground floor, or above a garage.
People already live in my basement. Will I get in trouble for asking?+
No. The check is private, between you and us. We tell you what it would take to make it legal, and you decide.
How long does the whole thing take?+
Design and Planning Board approval typically take 3 to 5 months depending on the city's calendar; construction, 2 to 4 months depending on the project. We give you dates after the visit.
Do you guarantee the city approves?+
No one can: the Planning Board decides case by case. What we guarantee is that your application arrives complete, architect-stamped and matched to every point of the ordinance. Construction doesn't start without approval.
Do you work outside Passaic?+
Yes, but this check and these rules are only for the City of Passaic. Every New Jersey town has its own ordinance.
