90,300 Office Buildings Are Being Turned Into Apartments Right Now
Min 1
A seismic shift is happening in commercial real estate that most residential investors are completely ignoring — and it's creating a once-in-a-generation opportunity to buy cash-flowing apartments at 30-50% below replacement cost.
At the start of 2026, 90,300 apartments were under construction from office conversions nationwide, up 28% year-over-year and up 291% since 2022 according to a new RentCafe report.
That's not a gradual trend. That's an explosion. Office conversions now account for 47% of all adaptive reuse projects in the United States — up from 42% just one year ago.
The 193,900 total future adaptive reuse units include hotels at 18% and industrial properties at 16%, but office conversions are dominating the pipeline by nearly 3-to-1 over any other property type.
Here's what's driving it: roughly $213 billion in office loans — about one-third of all U.S. office loans — are maturing by the end of 2026.
Those borrowers need to either pay them off or refinance them. With office vacancy nationwide sitting at roughly 19% according to CBRE data from the end of 2025, most of these properties can't refinance at anywhere close to their existing loan balances.
That means forced sales, distressed pricing, and massive opportunities for investors who understand the conversion economics.
Doug Ressler, senior analyst at Yardi Matrix, nailed it: the looming loan maturities are forcing property owners to make hard decisions.
You can't refinance a half-empty office tower at previous valuations when office demand has permanently declined. But you can convert that same building into apartments and tap into the strongest rental demand in decades. That arbitrage is creating the buying opportunity.

The geographic concentration of conversion activity tells you exactly where distressed office inventory is creating the biggest opportunities.
New York leads with 16,358 units in the office conversion pipeline — roughly twice as many as Washington D.C.'s 8,479 units and more than three times Chicago's 4,360 units.
Los Angeles and Dallas also show strong conversion totals, but the real story is the explosive growth in secondary markets.
Philadelphia jumped to 2,697 units in the conversion pipeline, more than doubling in just one year. Denver hit 2,991 units, also more than doubling year-over-year.
St. Louis saw similar growth.
These aren't coastal tech hubs with sky-high apartment rents. These are Midwest and mid-Atlantic markets where office conversion economics work because you're buying distressed office buildings for $50-$100 per square foot and converting them into apartments worth $200-$300 per square foot.
In 12 of the top 20 metro areas, office conversions make up more than 50% of adaptive reuse projects.
In Dallas and Minneapolis, that number hits 82%. In D.C. and Chicago, it's 64%. In New York, 62%. The pipeline is heavily concentrated in regions where office vacancy is highest and where distressed sellers are most desperate to exit.
CityHouse Old Town in Alexandria opened on March 19, 2026 as Old Town's first completed office-to-residential conversion. The property at 1101 King Street is already 40% leased despite just opening.
That's the market signal — strong rental demand is absorbing converted office buildings faster than new luxury construction in many markets.

The conversion economics are what make this opportunity accessible to sophisticated investors who understand value-add plays.
Building new luxury apartments in Los Angeles costs $450-$650 per square foot according to industry data. The entitlement process alone takes 3-5 years before you break ground. Total timeline from concept to stabilized occupancy: 6-8 years.
Compare that to office conversions. You buy a distressed office building for $100-$150 per square foot. You spend $150-$250 per square foot on conversion costs — new HVAC, plumbing, electrical, unit layouts, amenities.
Your all-in cost is $250-$400 per square foot for a finished apartment building in an established urban core location. You're 30-50% below replacement cost before you lease a single unit.
Los Angeles adopted the Citywide Adaptive Reuse Ordinance effective February 1, 2026, giving green light for large-scale conversion of non-residential buildings into multifamily housing.
The city faces 23% office vacancy with roughly 50 million square feet sitting empty, while simultaneously struggling with severe housing shortage. The new ordinance eliminates most of the zoning and permitting barriers that previously made conversions uneconomical.
That policy shift is happening nationwide. Cities are desperate to solve two problems simultaneously: empty office buildings destroying downtown tax bases and severe housing shortages driving residents to suburbs.
Office conversions solve both. You eliminate blight, you add housing supply, and you do it faster and cheaper than new construction.

The structural advantage office conversions give real estate investors is timing and capital efficiency.
While new construction developers are fighting through 3-5 year entitlement battles and spending $500+ per square foot, conversion investors are buying distressed assets at massive discounts and delivering product 2-3 years faster.
That speed-to-market advantage is worth millions in opportunity cost.
CommercialEdge estimates roughly 1.9 billion square feet of office space nationwide is suitable for conversion. That's the total addressable market.
In practice, far fewer buildings meet the criteria — you need appropriate floor plates, adequate natural light, reasonable ceiling heights, and viable plumbing/HVAC infrastructure.
But even if only 10-20% of that 1.9 billion square feet converts, you're talking about 190-380 million square feet of new apartment supply delivered at below-market costs.
For investors, the opportunity is buying into conversion projects early — either as equity partners in the conversion itself or as buyers of stabilized converted properties at prices well below new construction comps.
A converted office building in downtown D.C. delivering $2.50-$3.00 per square foot monthly rents at an all-in cost basis of $300 per square foot generates returns that new construction at $550-$650 per square foot simply can't match.
The distressed office market is creating forced sellers. Office buildings bought in 2016-2019 at $400-$600 per square foot are now worth $150-$250 per square foot as office assets.
Lenders are taking losses. Owners are walking away. That distress is the opportunity — you're buying the bones of well-located buildings at liquidation prices because the previous use case collapsed.

The democratization of this opportunity is what makes it actionable for investors without institutional capital. You don't need $50 million to play in office conversions.
Syndication structures and joint ventures let accredited investors participate with $50,000-$100,000 minimum investments. Real estate crowdfunding platforms are increasingly offering office conversion deals alongside traditional multifamily development.
The converted properties themselves create long-term buy-and-hold opportunities.
Once stabilized, a converted office building in downtown Chicago delivering 7-9% cash-on-cash returns with 30-40% built-in equity from below-replacement-cost basis is exactly the kind of asset that generates wealth over 10-20 year holding periods.
You're buying apartments in prime urban locations at suburban pricing because you're exploiting the office market dislocation.
The wave of conversions will reshape urban cores.
Downtown office districts that became ghost towns during COVID are getting second lives as residential neighborhoods.
That transformation creates spillover opportunities — retail, restaurants, services, parking, storage. Early investors in these transition neighborhoods will benefit from appreciation as the residential density builds and neighborhoods stabilize.
The $213 billion in maturing office loans by year-end creates urgency.
Lenders need to resolve these positions. Borrowers need exits. That forced selling will accelerate through late 2026 as maturity dates hit.
The best conversion opportunities will get snapped up by institutional players and sophisticated operators who move quickly. The window for retail investors to participate in top-tier deals is probably 6-12 months before competition drives pricing up.
Takeaway
The office-to-apartment conversion boom isn't speculation — it's the market solving a massive supply-demand imbalance through forced adaptation.
Empty office buildings are economic dead weight. Converting them into apartments that meet intense housing demand is the rational response.
The 90,300-unit pipeline represents just the beginning of a multi-year cycle where billions of square feet of obsolete office space gets repurposed.
For investors, the opportunity is recognizing that distressed office buildings are actually discounted apartment buildings in disguise. The bones are there. The locations are proven.
The only thing missing is the capital and expertise to execute the conversion. That's where smart money is positioning right now — finding experienced operators with conversion track records and partnering with them to buy distressed office assets at 40-60 cents on the dollar.
The biggest mistake investors will make is assuming office conversions are "too complicated" or "too risky" and sitting on the sidelines.
Yes, conversions require expertise in design, permitting, construction, and urban planning. But that's why you partner with operators who have that expertise rather than trying to DIY it.
The returns justify the complexity — 15-25% IRRs on successful conversion projects versus 8-12% on traditional multifamily development.
Focus on markets with high office vacancy, supportive conversion ordinances, strong rental demand, and meaningful price discounts between office and apartment valuations.
New York, D.C., Chicago, Philadelphia, and Denver all check those boxes based on current pipeline data. Secondary markets showing explosive conversion growth are often the best opportunities because competition is lower and distressed pricing is more extreme.
The 291% increase in conversion pipeline since 2022 signals this trend is just getting started. As more projects complete successfully and demonstrate the economics work, capital will flood into the space.
Get positioned now while most investors still think office conversions are niche plays. By 2027-2028, office-to-residential will be mainstream institutional strategy and the easy money will be gone.
