Why do ultra-luxury skyscrapers in major cities often sit entirely empty amidst severe local housing shortages?

When an Apartment Becomes an Asset First

A luxury tower can be full of finished apartments yet have few residents because its value to an owner may come from holding and reselling it, not from collecting rent. Buyers may treat a home in a major city as a place to park wealth, diversify investments, or keep available for occasional visits. If they expect its price to rise, renting it out can seem less important than preserving control of the property.

This does not mean every dark window signals an empty, investment-owned apartment. Some units are occupied intermittently, undergoing renovation, or part of a building that has not yet filled up. But ownership and everyday use can diverge: a home can count as housing in property records without serving as someone’s regular residence.

Why the Market Can Miss Local Needs

The economics of a high-end tower differ from those of housing most local households can afford. Developers and lenders may focus on buyers able to pay luxury prices, while rents from local workers would not cover the cost of building and financing those apartments. A developer can therefore have a strong reason to pursue a smaller number of expensive sales rather than build homes at lower prices—especially where land and construction are costly.

The result is a mismatch, not a simple shortage of physical space. An empty luxury unit does not automatically become an affordable home: its price, size, location, or upkeep costs may put it far beyond what a local household can pay. Yet when scarce land and building capacity go toward housing aimed at wealthy buyers, less may be built for other parts of the market.

What Vacancy Does—and Doesn’t—Solve

Whether an empty unit could help depends on why it is unused and what would make its owner rent or sell. Taxes on vacant homes, rules for short-term or nonresident ownership, and more construction at attainable prices are different policy tools; each addresses a different part of the problem. Simply pointing to dark windows cannot show which one would work.

The striking consequence is that a city can have both costly apartments with few occupants and residents struggling to find homes. The gap is not just between the number of buildings and the number of people—it is between what is being built, who can afford it, and whether owners choose to put it to everyday use.
