Why are New Jersey rents so high? Rutgers researchers identify four major pressures: insufficient housing supply, incomes failing to keep pace, widening inequality and greater consolidation among landlords and developers, all contributing to the state’s affordability problem.

New Jersey renters face some of the highest housing costs in the country, but a shortage of apartments is only part of the explanation.

For a closer look at current rental affordability, see our guide to New Jersey rent costs in 2026, including the income renters need and the gap between wages and housing costs.

A Rutgers University-Newark report examining rental affordability identified several forces behind rising housing costs, including undersupply, inflation, widening income inequality and greater consolidation among landlords and developers.

1. New Jersey does not have enough housing

New Jersey's housing supply has not kept pace with demand in many communities, particularly for smaller homes and units affordable to lower-income residents.

In September 2026, a state housing council concluded that New Jersey needs about 350,000 additional homes to keep pace with growth, improve affordability and remain competitive.

Rutgers researchers also found that housing shortages are especially significant in suburban areas, where decades of limited construction of smaller starter homes have reduced lower-cost options.

2. Rents have risen faster than many incomes

The widening gap between rent and earnings is easier to understand alongside our breakdown of how much income you need to live in New Jersey in 2026.

Housing becomes less affordable when rents rise faster than earnings.

Rutgers research found that over several decades, rents nationally have increased much faster than incomes, while real wages for the lowest-paid workers declined over a long period. The resulting gap leaves households spending a larger share of earnings on housing.

That gap is visible in New Jersey in 2026. A full-time worker needs $43.89 an hour to afford a modest two-bedroom rental at fair market rent, while the average New Jersey renter earns about $24.92 an hour.

3. Affordable rentals are particularly scarce

Adding housing does not automatically guarantee that lower-income renters can afford it.

Rutgers researchers found that the most severe shortage involves homes affordable to very low-income households. They argue that the affordability problem therefore requires both additional housing and preservation or creation of lower-cost units.

4. Landlord and developer consolidation can affect rents

The Rutgers report also points to consolidation in the real-estate industry.

Its review found that large professional or corporate property owners tend to set higher rents than very small landlords, while consolidation among homebuilders can influence the cost and type of housing being produced.

Rent is only one part of the pressure facing households, and our broader guide explains why New Jersey is so expensive to live in across housing, taxes and everyday expenses.

New Jersey's rent problem is therefore broader than simple supply and demand. Building more homes could ease pressure, but affordability also depends on wages, the type of housing constructed, preservation of lower-cost rentals and how the rental market is structured.

With New Jersey now ranked as the fifth most expensive state for renters, those factors are likely to remain central to the state's housing debate.
