Report: 1 Million New Rental Housing Units to Be Ready by 2025

A Historic Construction Boom

According to a RentCafe apartment construction analysis, approximately 1.2 million rental units were added to the U.S. housing stock between 2020 and 2022, with roughly 1 million additional units projected to come online by 2025. The report highlighted a multifamily construction pace that had not been seen in decades, driven by pandemic-era demand, low interest rates during the initial buildout phase, and pent-up household formation.

Where the Units Were Going

The report identified New York, Dallas, Miami, Austin, and Phoenix among the metros leading the country in new rental deliveries. Sun Belt markets dominated the pipeline, with developers responding to population inflows and lower construction costs compared with coastal cities. New York metro stood out on the East Coast with tens of thousands of new units expected in 2023 alone.

Affordability Concerns Behind the Headlines

While the headline number suggested rental supply was catching up with demand, the same analysis flagged a mismatch in affordability. A large share of the new deliveries were classified as high-end or luxury product, leaving lower- and middle-income renters with fewer options even as overall inventory grew. This disconnect between total supply and attainable supply has been a recurring theme in housing research throughout the cycle.

How the Forecast Actually Played Out

Subsequent industry data from RentCafe and the National Apartment Association indicates that the supply wave materialized — but unevenly. Completions peaked in 2024, then moderated in 2025 as construction starts fell sharply in response to higher interest rates, tighter bank lending standards, and rising costs for labor, land, and materials. RentCafe later reported that more than 500,000 new apartments opened in 2025, a strong figure by historical standards but below the 2024 peak.

What It Means for Renters and Homeowners

For renters, the surge in new supply contributed to softening rent growth in many Sun Belt markets, with some metros seeing year-over-year rent declines. For prospective homeowners, elevated apartment supply may ease pressure on household budgets and help would-be buyers save for down payments, though affordability at the purchase end of the market has remained constrained by mortgage rates and home prices.

Looking Ahead

As the 2020–2025 supply wave finishes delivering, the pipeline of new apartment starts has contracted significantly. Analysts expect thinner deliveries in 2026 and beyond, which could put renewed upward pressure on rents once the current glut is absorbed. For policymakers focused on housing affordability, the report and its follow-ups underscore that raw unit counts tell only part of the story — the composition and location of new housing matter just as much.
