ADU Eligibility Quick-Check

An Accessory Dwelling Unit (ADU) is a smaller, independent living unit on the same lot as a single-family home: converted garages, detached cottages, basement or attic conversions, and attached additions all qualify. Most states have streamlined ADU permitting since 2020, but local rules still control size, height, and setback.

Is your lot zoned single-family or multi-family residential?
Does your lot have at least 1,200 sq ft of buildable space?
Is your existing home owner-occupied (in most states this is not required, but some require it for ADU permits)?
Will the ADU stay under your state's size cap (commonly 850-1,200 sq ft for detached)?
Can you provide one off-street parking space (waived in many states within 0.5 mi of transit)?

If you answered 'yes' to most of these, you likely qualify in New Jersey under recent ADU streamlining laws. The Paterson, NJ rules below cover local size, height, and setback requirements.

Full Breakdown

Under § 500-3.6.B.1, the accessory-structure rules that apply in every residential zone include one flat prohibition: no accessory building or structure can be used for human habitation. That rules out garage apartments, converted sheds, and any other backyard second unit built as an accessory structure rather than a code-defined dwelling. The prohibition sits in Article V, the portion of the 2016 Zoning and Land Development Ordinance the City Council certified as current, and nothing elsewhere in the ordinance's definitions or use tables creates an accessory-apartment or in-law-suite exception to it. A homeowner wanting a second unit would need it recognized as a genuine two-family dwelling under the district's principal-use rules, not as an accessory structure.

Violations & Fines

Living in or renting out a garage, shed, or other accessory structure violates § 500-3.6.B.1 and can trigger a zoning enforcement action and denial of a certificate of occupancy.

Frequently Asked Questions

Can I build an ADU above my garage in Paterson?

No. § 500-3.6.B.1 bars any accessory building from being used for human habitation, so garage apartments aren't allowed as accessory structures.

Is there an in-law suite exception in Paterson's zoning code?

None found in Article V; a second unit would have to qualify as a genuine two-family dwelling, not an accessory structure.
