The U.S. housing / real estate market is grappling with a record-breaking deficit of 4.7 million homes, according to a new Zillow analysis of Census data, exacerbating the nation’s affordability crisis.
Despite a robust construction surge, the supply of new homes continues to fall short of demand, leaving millions of families in precarious living situations.
Meanwhile, a separate Zillow report highlights a silver lining for landlords: embracing pet-friendly rentals can significantly boost leasing speed and tenant engagement, offering a strategic advantage in a competitive market.
The housing shortage, which grew by 159,000 homes in 2023, marks an all-time high, driven by a persistent mismatch between population growth and housing construction.
In 2023, builders added 1.4 million new homes to the U.S. housing stock, up from 1.3 million in 2022, with completions reaching 1.45 million units in 2023 and 1.63 million in 2024—the highest annual totals since 2007.
However, these efforts failed to keep pace with the formation of 1.8 million new families, many of whom are now forced to “double up” with unrelated individuals due to a lack of affordable options.
Zillow estimates that 8.1 million families were sharing homes with non-relatives in 2023, compared to just 3.4 million vacant homes available for rent or sale.
This 4.7 million-unit gap underscores the severity of the crisis, particularly in major metros like New York, Los Angeles, Boston, San Francisco, and Washington, D.C., which face the largest deficits.
The affordability crisis is hitting younger generations the hardest. Millennials, who represent 38% of those doubling up, are increasingly priced out of homeownership.
Zillow notes that a median-income household would need a $17,670 raise to afford a typical U.S. home’s mortgage payments, assuming a 20% down payment.
High mortgage rates and soaring home prices further exacerbate the challenge, with baby boomers now outpacing millennials as the largest group of homebuyers.
The root cause of this crisis traces back to nearly two decades of underbuilding, a trend that began during the Great Recession and has not been reversed despite recent construction booms.
Zillow’s senior economist, Orphe Divounguy, emphasizes that “we still don’t have enough housing in this country for people who need it,” pointing to restrictive zoning laws and building regulations as key barriers.
Areas with fewer restrictions have seen faster construction responses to demand, leading to slower price and rent growth, but broader systemic changes are needed.
Industry professionals advocate for relaxing zoning laws to allow for higher-density housing, such as accessory dwelling units (ADUs), duplexes, and triplexes, which could create millions of new homes if implemented in major markets.
On the rental front, Zillow’s analysis of over 11 million listings from 2024 reveals that pet-friendly rentals are a game-changer for landlords.
With nearly 60% of renters now owning pets—up from 46% pre-pandemic—properties that allow pets are leased eight days faster on average than those that don’t.
In high-demand markets like New York City, pet-friendly rentals lease 26 days faster, with significant time savings also seen in Tampa (16 days), Columbus (12 days), and Austin (10 days).
Cities in Texas, such as Austin (80%), Dallas (79%), and San Antonio (78%), lead the nation in pet-friendly rental listings, while Houston lags at just 38%.
Emily McDonald, a Zillow rental trends expert, notes that “allowing pets can be a strategic edge for landlords competing to fill units,” as pet-friendly listings attract more views, saves, and shares.
However, stricter pet policies in markets like Providence (43%) and San Jose (44%) limit options for pet-owning renters, nearly half of whom have passed on properties due to restrictive policies.
As the housing / property market deficit continues to strain affordability, innovative solutions like pet-friendly rentals offer immediate relief for landlords and renters alike.
However, long-term progress hinges on policy reforms to boost housing supply, particularly in high-demand urban centers.
Until then, millions of US consumers will continue navigating a market where demand far outstrips supply, pushing the goal of homeownership further out of reach.
