Frequently Asked Questions
Is the Ironbound neighborhood in a flood zone after Hurricane Ida?
Portions of the Ironbound neighborhood experienced severe flooding from the Passaic River during Hurricane Ida in 2021 — one of the worst flood events in Newark's history. FEMA has been updating flood maps post-Ida. Properties near the Passaic River in the Ironbound should check the most current FEMA Flood Insurance Rate Map at msc.fema.gov. The Passaic River Flood Reduction Project by the Army Corps of Engineers provides additional flood barriers, but the project's effectiveness and scope continue to evolve.
Can I build an ADU on my Newark property?
Yes — Newark allows accessory dwelling units on residential lots. Detached ADUs up to 700 sqft are allowed in rear or side yards. No owner-occupancy requirement. Near NJ Transit stations, parking requirements may be waived. Newark's affordable housing policy supports ADU construction and permit fees are generally lower than neighboring Jersey City.
What are Newark's rules for operating a business from home?
Newark allows home occupations that are secondary to residential use. No separate permit required. You cannot have employees who don't live in your home, customer visits, commercial vehicles parked on premises, or exterior signage. New Jersey's cottage food law allows Newark residents to sell home-prepared foods directly to consumers up to $50,000 per year — a relatively permissive limit. NJ Department of Health registration is required for cottage food operations.
What transit options are available for Newark residents?
Newark has exceptional transit access.

NJ Housing and Mortgage Finance Agency (HMFA) programs provide low-interest loans for homeowners. Federal Historic Tax Credits apply to properties in National Register Historic Districts. Newark participates in NJ's Urban Enterprise Zone which provides some business tax benefits. Contact NJHMFA and Newark DHCA for current program availability and income requirements.
What is the noise impact from Newark Airport on residential properties?
Newark Liberty International Airport creates aircraft noise that affects properties primarily under major flight paths. The FAR Part 150 Noise Compatibility Program identifies noise-impacted areas around the airport. Properties in 65+ DNL (Day-Night Level) noise zones face the most significant impact. The Port Authority of NY/NJ offers voluntary soundproofing assistance for properties within certain noise contours. Check the airport's current noise contour maps at panynj.gov or contact the FAA for Part 150 study information.
