D.C. Mun. Regs. tit. 10-A, § 509
509.1 Along with increasing housing and affordable housing supply, preservation of housing in the District is critical. This section focuses on two aspects of housing preservation: retaining affordable housing units specifically and retaining existing housing stock generally.
509.2 The affordability of the District has been declining over the past five years, even though funding for affordable units has increased. This has been due to a combination of both the expiration of federal subsidies and rising market rents and sales prices. Between 2006 and 2017, the number of rental units affordable to households earning less than 60 percent of the MFI decreased by close to 18,300 units. Figure 5.10 also shows that the number of rental units affordable to those earning more than 60 percent increased by approximately 44,800. Over the same period, the median sales prices of homes rose almost 7.3 percent per year, while condominiums rose 2.8 percent per year. Between 2006 and 2017, the area’s MFI rose by an average compounded rate of less than 1.8 percent a year. These changes have been especially hard on the District’s lowest-income residents, particularly renters who are older adults and those on fixed incomes. These impacts are likely experienced more broadly and deeply for communities of color, given the racial differences in median family income.

509.4 An important part of housing preservation is the maintenance and modernization of existing housing stock and its components, such as heating and air conditioning systems. Almost 62 percent of the housing units in Washington, DC are in buildings that are over 55 years old, and many are over 100 years old. The rise in home prices has been accompanied by a rise in building material and labor costs, making it expensive for many owners to care for their properties. In some parts of the Washington, DC, lack of maintenance by absentee landlords may jeopardize the longevity of the housing stock and negatively affect neighborhood character.
Maintenance and energy upgrades will continue to be an issue in the future as the existing housing stock grows older and construction, utility, and maintenance costs increase.
