Washington, DC Needs More Housing. So Why Is It So Hard to Build?

Washington, DC’s housing challenge sounds simple: people need homes they can afford, so the city needs to build more of them. But there is a problem hiding inside that solution. A new apartment building must earn enough money to justify the cost of creating it—and the rent required to make the numbers work may be far above what many households can pay.

That does not mean every proposed apartment building is unprofitable. It means that the question of how many homes a city needs is different from the question of which homes can actually be financed. Understanding the gap between the two is essential to understanding why new housing can be slow, expensive, or dependent on public support.

The rent problem starts long before anyone signs a lease

Developers must acquire land, design a building, obtain approvals, arrange financing and pay for construction before the property begins collecting rent. Once occupied, the building must pay for maintenance, insurance, taxes, management and reserves. Its remaining income must support financing and justify the risk of development.

A 2025 analysis by affordable housing developer True Ground illustrates the scale of these costs. Across ten of its ground-up projects in the DC region, the average total development cost was $516,263 per apartment in 2025 dollars. About $323,931 went to hard construction, $142,803 to soft costs and $49,528 to land acquisition. The sample is not a DC-wide market-rate benchmark: eight projects were in Arlington, one in Fairfax and one in DC, and all had underground parking.

What happens when the numbers do not line up?

Consider a deliberately simplified example: a 100-unit building costing $50 million, or $500,000 per apartment. Assume 5% vacancy, operating expenses equal to 38% of effective rental income, a 5.5% valuation cap rate, and a requirement that the completed property be worth at least 10% more than its development cost. Under those assumptions, average monthly rent must be approximately $4,280 per apartment to meet the model’s valuation threshold.

Now compare that figure with a real market observation. In the first quarter of 2025, DC’s reported effective monthly rent for Class A apartments was $2,880, with 11.5% vacancy. The modeled rent is about 49% higher. This is a warning signal, not proof that DC development is infeasible: one figure is a hypothetical new-building threshold, while the other describes an existing portfolio of apartments of different sizes, ages and locations. A specific project would need site-specific cost, rent and financing evidence before reaching a feasibility conclusion.

Why higher rents are not always the answer

A developer cannot simply charge whatever rent the construction budget requires. Households have income limits, and competing apartments place a ceiling on what the market will bear. If a building requires rents above that ceiling, the developer must change something: acquire less expensive land, redesign the building, reduce costs, contribute more equity, accept a lower return, secure public assistance—or decide not to proceed.

The same dilemma is sharper for income-restricted housing. If a household’s rent is capped below what the property needs to support its costs, the project needs another source of value or financing. This is why an affordable apartment can be socially necessary yet financially difficult to produce.

The overlooked cost of complexity

Construction costs are only part of the story. Multiple approvals, financing sources and review processes can add months of carrying costs and require teams of lawyers, architects, lenders and consultants. True Ground notes that its projects often combine five to ten financing sources, each with a separate review process. Even when each requirement has a legitimate purpose, the cumulative cost matters.

A useful housing policy debate therefore asks not only how much public money to invest, but which costs can be reduced without compromising safety, quality or affordability. Faster predictable approvals, appropriately designed parking rules and better coordination among lenders may affect whether a project can move forward.

What this means for DC

DC does have tools to help bridge the financing gap. Its Housing Production Trust Fund provides affordable housing financing, while federal and local tax credits can bring equity into eligible developments. In 2026, the District also introduced a rolling application process intended to better align funding decisions with when projects are ready to close. Those tools matter—but they lead to a second question: when the private market cannot pay the full cost of affordable housing, who pays the difference?

That is the subject of the next article in this series. The first conclusion is more basic: housing need does not automatically create a financeable housing project. If we want more homes, we have to understand both what they cost and what their future residents can afford.
